Q: Convert PyTorch Trained Model To Core ML model I'm a newbie in python. I have model.ckpt file. I want to convert that model to core ML model .mlmodel to using in iOS project. I have spent a lots of time to research but I don't know how to do it. Someone told me use coremltools but I could not find tutorial how to do that. This code bellow is not work.
coreml_model = coremltools.converters.keras.convert('./model.ckpt',
                                                input_names='image',
                                                image_input_names='image',

SS Yongala (Wrack)
Orientation & Geography
Australia, Queensland
The passenger ship SS Yongala sank off Cape Bowling Green, Queensland, Australia on 23 March 1911. En route from Melbourne to Cairns she steamed into a cyclone and sank south of Townsville. Traces of the ship were found days later as cargo and pieces of wreckage washed ashore at the Cape and at Cleveland Bay, and suggested that the bottom of the ship had been ripped by a hidden rock. All one hundred and twenty-two people on board perished in what is considered one of the most tragic incidents in Australian maritime history. It was only in 1958 that the wreck of the Yongala was discovered lying in waters south of Townsville, and it has since become renowned as an internationally regarded diving and tourist destination.

Battle of Times Square
By Ann Oldenburg, USA TODAY
Ten. Nine. Eight. ...
Dec. 31, 2003: Dick Clark's last appearance at his New Year's Rockin' Eve, before his stroke.
New Year's Eve revelers have been gathering in midtown Manhattan for decades to ring in a new page on the calendar.
But this year, Times Square is shaping up to be a battleground for broadcasting as ABC, NBC, Fox, Fox News Channel, MTV, CNN, PBS and ESPN all plan to air special live telecasts from the patch of land that has become New York's biggest party scene for one night each year. (Related story: Contenders spar for attention in Times Square)
In one corner: Regis Philbin, 74, a legend of live TV, working for Fox.
In another, Dick Clark, 76, making his first appearance since having a stroke last December, with sidekick Ryan Seacrest, 31, on ABC.
Also on the scene: competitive Carson Daly, 32, making his first Times Square appearance on New Year's Eve for NBC.
And that's not taking into account MTV's army of young VJ hosts who claim that they have the best spot in town because their studios span almost a block of Times Square territory.
ESPN is making its first foray into a New Year's Eve broadcast by televising rocker Steven Van Zandt's Little Steven's Underground Garage syndicated radio show, live, from the Hard Rock Cafe in Times Square.
"Even King Kong is doing a New Year's Eve show," Philbin cracks. "It has really blossomed."
An icon's homecoming
This year marks a particularly special event: the return of Clark, who missed last year's show. He has done no interviews or public appearances since his stroke, and tabloids have painted a grim picture of his health.
"Could Dick have done TV before now? Absolutely," says Larry Klein, longtime Clark pal and producer of Dick Clark's New Year's Rockin' Eve. "Did he want to? No." Klein adds, "This show is very important. He wanted his coming-out party to be his comeback."
Adds Paul Shefrin, Clark's personal publicist: "We've had tons of offers to do things." But Clark, always a keen businessman, wanted to wait and unveil himself to millions at once.
Typically, Clark's show — this will be the 34th year it has aired — dominates the night in ratings. Last year, even without the world's oldest teenager on the scene, Rockin' Eve clocked an average 7.9 million viewers in its prime-time portion (10-11 p.m.), the night's top show. Fox's New Year's Eve fest drew 5.7 million. NBC and Carson Daly finished with 4.5 million. On cable, MTV drew 1.9 million.
Klein says viewers can expect Clark's speech to be "terrific" and to see him up and about as host.
"He's not tied to a bed," Shefrin says. "That doesn't mean he's going to be running around the block."
For Ty Tindell, 29, a New Year's TV fan in Howard County, Md., the night is about one thing: "Dick Clark, Dick Clark, Dick Clark. New Year's Eve is not complete without the legend," he says, adding that the live performance by Mariah Carey on Clark's show also is a draw for him.
"We get two treats this year: finally, a real singer who isn't 13 and lip-syncing, and Dick Clark returns. I am actually considering going to Times Square to celebrate with Dick and Mariah."
Enter Ryan Seacrest
This year, the legend will have a protégé. Ryan Seacrest has signed a long-term deal to be involved as executive producer and host of the Rockin' Eve show, eventually taking the baton from Clark.
"Two years ago, I worked up a list of names, a ton of names, for the future," Klein says. "This person, that person.
"But a year ago, that list went from a ton of names to one: Ryan."
Why? "Just by Ryan doing his job, just by Ryan being who he is, he brings a freshness and a new vitality and carries on the tradition of what Dick has done for years, just by being who he is."
Seacrest, who grew up in Atlanta, remembers watching TV on New Year's Eve each year. His parents would go out, leaving $12 on the table for his babysitter to order pizza. He'd have a cider spritzer and watch Clark count down.
"Dick Clark — his middle name? New Year's Eve," says the American Idol master of ceremonies, who last year helmed the Fox New Year's Eve show. "I knew when I was on other shows, I knew we weren't going to beat Dick Clark. He is New Year's Eve."
Now, Seacrest is "the next Dick Clark," as he has been called many times. "We don't have the same hair, but I'd be extremely honored. I don't think you can ever replace Dick Clark."
The challengers line up
Phil Gurin, executive producer of the rival Fox show, says it will be a friendly competition on New Year's in Times Square.
"I wish Ryan the best. We go off at 12:30 a.m., and we're all hoping to go have a drink somewhere after the shows."
Representatives of all of the shows say the goal is to bring Times Square to the viewers as best they can. That's why Philbin plans to lead the Times Square crowd in a sing-along.
"It's Regis for the people," says Philbin, who sounds as if he's unleashing a battle cry. Last year, he filled in for Clark on ABC.
"I was in Times Square for the first time, even though I grew up in New York City. I really was kind of overwhelmed by the intensity and electricity of the whole thing. It's a once-a-year, one-of-a-kind type of ceremony, and it makes for great television to see that whole throbbing mass."
As for switching networks, he says, "my contract frees me to do whatever I want to do in the evening, and I admire Fox. They're very innovative."
He's happy to help
Still, he concedes: "ABC and Dick have the franchise. They've got the brand for it. Of course, a lot of folks will want to welcome Dick back. Then you've got Ryan Seacrest added to the mix. I think it's going to be pretty much impossible to beat them in a rating, but if I can help Fox increase whatever they have, I'll be happy."
The tradition of covering New Year's Eve goes back to NBC's live radio broadcasts from Times Square hosted by legendary announcer Ben Grauer in the 1940s. It continued into the age of television with The Tonight Show Starring Johnny Carson.
Daly was host of his first New Year's Eve for NBC last year from Rockefeller Center, about a five-minute walk from Times Square. This year, he says, he believed it was important to be in the midst of the real action.
"I feel like this year, we're in the big leagues," he says. "Our main objective is to be live starting at 11:30 p.m. to show the sights and sounds of Times Square and the ball dropping." He says he didn't want "a giant mishmash of pre-produced things."
As for going up against veterans Philbin and Clark, he says, "I feel honored. I've made no bones about my thoughts for both of them, especially for Mr. Clark, who I think the world of. I've modeled a lot of what I've tried to do after him, and he's been very supportive."
But isn't television on New Year's Eve only for losers who don't have an invitation to a wild party?
Says Daly, laughing: "Attention, nerds! Turn your TV on to NBC." He adds, "I think it's a great night to stay home."
For Dawn Clark of Glastonbury, Conn., staying home is a family tradition.
"When I started high school and continued on into college, I felt it was necessary to go to parties, but I still long for the days of watching Dick Clark and eating Cool Ranch Doritos," says Clark, 25. "I sometimes recorded the last couple of hours so I could see the musical performances and watch the ball drop, in case wherever I was didn't have the television on."
She predicts that the Clark/Seacrest team will be the best because "they are just so into it. They seem like they're having fun and happy to be there, and seeing that kind of genuine emotion is heartwarming. Carson Daly approaches most things he does with an 'I'm too cool for this' attitude, and even when he tries to be excited, I don't buy it. I'm sure Regis will be fine, and my grandmother will enjoy watching him very much."
Reaching for a younger audience, MTV has a big party planned and has just the location for it.
"I feel like we kind of have an advantage because we've taken over Times Square in a way," says Damien Fahey, 25, one of the hosts of the show. He explains that the second-floor MTV studios take up almost an entire block.
But, he says, "it really isn't a competitive thing. It's kind of like, 'It's New Year's.' Everyone's on the same page as far as attitude goes — we all just want to have a good time. I don't want to beat anybody.
"If you're into live music and the whole Times Square thing, you'll watch our show, I hope. It's more about everyone getting together and having a good time." Besides, he says, "we'll get together after the MTV New Year's Eve Show. Every year, Carson has a party."
At home, 'in your PJs'
Whether you're actually in Times Square or tuning in on television, rituals are a big part of the night.
"My husband and I always stay in for New Year's Eve," says Lisa Rutherford, 39, of Homestead, Fla. It's a tradition they've held for the past 12 years or so, she says.
"We have 'fun food' and champagne, play board games and watch When Harry Met Sally every year. At about 11:30, we turn on Dick Clark and watch the ball drop. It is our New Year's tradition, and we look forward to it every year. Although Regis did a fine job last year, we did miss Dick Clark. We'll be watching for him this year.
"New Year's is best spent in the comfort of your own home, in your PJs, with the one you love."

Italian Studies (Review): Hard to Grasp, Easy to Feel
Films, Reviews
Vanessa Kirby in Italian Studies (Brett Nobar / Magnolia Pictures)
Euphoria Season 2 Episode 1 Recap/Review: A Slow Return to Form
Italian Studies is a masterclass of dreamlike, disorienting filmmaking, which makes the film inviting even when its meaning remains unclear.
There are two categories of film that I find the hardest to talk about: films that are so thoroughly unremarkable that there's very little to say, and films that generate an emotional response despite not being logically clear. Italian Studies falls firmly in that second category. Written and directed by Adam Leon, this film stars Vanessa Kirby as a woman who inexplicably finds herself losing her memories, not even knowing what her own name is. As she wanders New York City, she comes across several younger individuals, including a man named Simon (Simon Brickner), by whom she finds herself seemingly inspired to write a novel … one that may possibly be a follow-up to a series of short stories that she might have authored.
Italian Studies is a film that I enjoyed watching from start to finish. Never did a moment pass where I wasn't invested in seeing where it was going. But due to its confounding nature, if you were to ask me what it's really about or what exactly happens throughout, I would be drawing a bit of a blank. So, at this point, I can't be sure whether or not this film's story makes sense for what it's trying to do. What I can say without question is that Italian Studies is a masterclass at deliberately disorienting filmmaking. The first half in particular tries to put you in a similar state to our lead: confused, trapped in some uncanny valley, unsure of what's happening or why. This is achieved to incredible effect through techniques such as the distortion of images through glass and light (including some beautiful golden lens flares that add an almost ghostly aura), blocking that often puts the actors partially out of the frame, handheld camerawork, objects passing in front of the shots so that you can never really grasp the moment, abrupt transitions from one scene to the next, and even dialogue that's out of sync before going back into sync within the same shot, blurring one's sense of passing time.
All of these choices would be just incompetent filmmaking in a more straightforward story, but they thrive here because they take away the viewer's sense of stability and structure. The grainy quality, somewhat tight aspect ratio and several shots that frame a character through a smaller "window" (like through a bookcase or in narrow spaces between walls) also add to the sense of entrapment in this disorienting state. There is rarely a steady, fully clear shot that puts you at ease, and the film feels very much like a fever dream. That is, until our main character begins her "mission" in the second half. This is where the filmmaking of Italian Studies begins to stabilize a bit, which I interpret as indicative of the character now finding some semblance of clarity in this new pursuit of hers. It's this shift, as well as the many beautifully composed shots that couldn't have been achieved without serious talent involved, that lead me to believe that every unconventional filmmaking choice in Italian Studies was intended exactly as I've just described, rather than accidentally working out that way.
Vanessa Kirby in ITALIAN STUDIES, a Magnolia Pictures release. (Magnolia Pictures)
But it's not just because of the filmmaking that I was drawn into this story. Vanessa Kirby is magnetic as always. She doesn't go for a more panicked performance like some may have in this role, but rather she portrays a woman who is trying to keep herself collected and maintain a hold of what little order she has. Someone who nearly steals the show from her is Simon Brickner, who takes what could have been very grating dialogue and gives it its own very endearing personality. He plays a young man trying to figure out his life in a sense, which makes him an interesting companion to our lead, who is literally trying to figure out her life. The performances all around carry a lot of introspective weight to them as every character contemplates their pasts, their loves, their desires, and the dilemmas of whether or not to change for the world or demand the world change for them.
As you may suspect from its premise, Italian Studies is designed to confuse viewers as to what's really happening, when it happened, or even if it happened, to a point where even now, I couldn't tell you the correct order of events. I can, however, discern that there's some sort of suggested cyclical nature to everything. Events that occurred in the past are being mirrored to some degree, such as Kirby's character gathering with these younger people and being inspired by them. Without giving anything away, I think that she is indeed who she begins claiming to be, and that she's being driven by the impulses that possibly stem from the remnants of her missing memories. Or maybe that drive speaks to who she is as a person even without those memories. The main theme of Italian Studies seems to be the chase for fulfillment that often sends people in circles, bringing us down different versions of the same path. The journey our protagonist takes is possibly an extreme, unexplained manifestation of that. Or maybe she's not who she claims to be and is simply fulfilling a void through another person's life.
More Than Ever (Film Review): "Everything We Will Never Be Again"
This is all a very uncertain analysis on my part. I do plan on rewatching the film to see if anything I'm saying or thinking holds water, if I end up having a different interpretation, or if there's not really anything meaningful at all to be found here. Whatever I end up making of Italian Studies down the line, though, I can't deny that the raw experience of watching it is very enjoyable. It's so well-crafted and well-performed that I'm giving it the benefit of the doubt to some degree that it knows what it's doing narratively, while still being cautious. Italian Studies is definitely one of those films you need to feel before you begin to understand. That's always a huge gamble, and I've had my share of such films that I ended up not liking, even with some critically acclaimed works like The Green Knight. So, I can completely understand why anyone would dislike this film. But something this unique and distinguished, as well as refreshingly short, is at least worth one viewing.

Roger Larsson, "Flight Test System Identification", Linköping Studies in Science and Technology. Dissertations, No. 1990, 2019.
AbstractKeywordsBiBTeXDOIFulltext
With the demand for more advanced fighter aircraft, relying on unstable flight mechanical characteristics to gain flight performance, more focus has been put on model-based system engineering to help with the design work. The flight control system design is one important part that relies on this modeling. Therefore, it has become more important to develop flight mechanical models that are highly accurate in the whole flight envelope. For today's modern fighter aircraft, the basic flight mechanical characteristics change between linear and nonlinear as well as stable and unstable as an effect of the desired capability of advanced maneuvering at subsonic, transonic and supersonic speeds.
This thesis combines the subject of system identification, which is the art of building mathematical models of dynamical systems based on measurements, with aeronautical engineering in order to find methods for identifying flight mechanical characteristics. Here, some challenging aeronautical identification problems, estimating model parameters from flight-testing, are treated.
Two aspects are considered. The first is online identification during flight-testing with the intent to aid the engineers in the analysis process when looking at the flight mechanical characteristics. This will also ensure that enough information is available in the resulting test data for post-flight analysis. Here, a frequency domain method is used. An existing method has been developed further by including an Instrumental Variable approach to take care of noisy data including atmospheric turbulence and by a sensor-fusion step to handle varying excitation during an experiment. The method treats linear systems that can be both stable and unstable working under feedback control. An experiment has been performed on a radio-controlled demonstrator aircraft. For this, multisine input signals have been designed and the results show that it is possible to perform more time-efficient flight-testing compared with standard input signals.
The other aspect is post-flight identification of nonlinear characteristics. Here the properties of a parameterized observer approach, using a prediction-error method, are investigated. This approach is compared with four other methods for some test cases. It is shown that this parameterized observer approach is the most robust one with respect to noise disturbances and initial offsets. Another attractive property is that no user parameters have to be tuned by the engineers in order to get the best performance.
All methods in this thesis have been validated on simulated data where the system is known, and have also been tested on real flight test data. Both of the investigated approaches show promising results.

Bertil Grelsson, "Vision-based Localization and Attitude Estimation Methods in Natural Environments", Linköping Studies in Science and Technology. Dissertations, No. 1977, 2019.
Over the last decade, the usage of unmanned systems such as Unmanned Aerial Vehicles (UAVs), Unmanned Surface Vessels (USVs) and Unmanned Ground Vehicles (UGVs) has increased drastically, and there is still a rapid growth. Today, unmanned systems are being deployed in many daily operations, e.g. for deliveries in remote areas, to increase efficiency of agriculture, and for environmental monitoring at sea. For safety reasons, unmanned systems are often the preferred choice for surveillance missions in hazardous environments, e.g. for detection of nuclear radiation, and in disaster areas after earthquakes, hurricanes, or during forest fires. For safe navigation of the unmanned systems during their missions, continuous and accurate global localization and attitude estimation is mandatory.
Over the years, many vision-based methods for position estimation have been developed, primarily for urban areas. In contrast, this thesis is mainly focused on vision-based methods for accurate position and attitude estimates in natural environments, i.e. beyond the urban areas. Vision-based methods possess several characteristics that make them appealing as global position and attitude sensors. First, vision sensors can be realized and tailored for most unmanned vehicle applications. Second, geo-referenced terrain models can be generated worldwide from satellite imagery and can be stored onboard the vehicles. In natural environments, where the availability of geo-referenced images in general is low, registration of image information with terrain models is the natural choice for position and attitude estimation. This is the problem area that I addressed in the contributions of this thesis.
The first contribution is a method for full 6DoF (degrees of freedom) pose estimation from aerial images. A dense local height map is computed using structure from motion. The global pose is inferred from the 3D similarity transform between the local height map and a digital elevation model. Aligning height information is assumed to be more robust to season variations than feature-based matching.
The second contribution is a method for accurate attitude (pitch and roll angle) estimation via horizon detection. It is one of only a few methods that use an omnidirectional (fisheye) camera for horizon detection in aerial images. The method is based on edge detection and a probabilistic Hough voting scheme. The method allows prior knowledge of the attitude angles to be exploited to make the initial attitude estimates more robust. The estimates are then refined through registration with the geometrically expected horizon line from a digital elevation model. To the best of our knowledge, it is the first method where the ray refraction in the atmosphere is taken into account, which enables the highly accurate attitude estimates.
The third contribution is a method for position estimation based on horizon detection in an omnidirectional panoramic image around a surface vessel. Two convolutional neural networks (CNNs) are designed and trained to estimate the camera orientation and to segment the horizon line in the image. The MOSSE correlation filter, normally used in visual object tracking, is adapted to horizon line registration with geometric data from a digital elevation model. Comprehensive field trials conducted in the archipelago demonstrate the GPS-level accuracy of the method, and that the method can be trained on images from one region and then applied to images from a previously unvisited test area.
The CNNs in the third contribution apply the typical scheme of convolutions, activations, and pooling. The fourth contribution focuses on the activations and suggests a new formulation to tune and optimize a piecewise linear activation function during training of CNNs. Improved classification results from experiments when tuning the activation function led to the introduction of a new activation function, the Shifted Exponential Linear Unit (ShELU).

Yuxin Zhao, "Gaussian Processes for Positioning Using Radio Signal Strength Measurements", Linköping Studies in Science and Technology. Dissertations, No. 1968, 2019.
Estimation of unknown parameters is considered as one of the major research areas in statistical signal processing. In the most recent decades, approaches in estimation theory have become more and more attractive in practical applications. Examples of such applications may include, but are not limited to, positioning using various measurable radio signals in indoor environments, self-navigation for autonomous cars, image processing, radar tracking and so on. One issue that is usually encountered when solving an estimation problem is to identify a good system model, which may have great impacts on the estimation performance. In this thesis, we are interested in studying estimation problems particularly in inferring the unknown positions from noisy radio signal measurements. In addition, the modeling of the system is studied by investigating the relationship between positions and radio signal strength measurements.
One of the main contributions of this thesis is to propose a novel indoor positioning framework based on proximity measurements, which are obtained by quantizing the received signal strength measurements. Sequential Monte Carlo methods, to be more specific particle filter and smoother, are utilized for estimating unknown positions from proximity measurements. The Cramér-Rao bounds for proximity-based positioning are further derived as a benchmark for the positioning accuracy in this framework.
Secondly, to improve the estimation performance, Bayesian non-parametric modeling, namely Gaussian processes, have been adopted to provide more accurate and flexible models for both dynamic motions and radio signal strength measurements. Then, the Cramér-Rao bounds for Gaussian process based system models are derived and evaluated in an indoor positioning scenario.
In addition, we estimate the positions of stationary devices by comparing the individual signal strength measurements with a pre-constructed fingerprinting database. The positioning accuracy is further compared to the case where a moving device is positioned using a time series of radio signal strength measurements.
Moreover, Gaussian processes have been applied to sports analytics, where trajectory modeling for athletes is studied. The proposed framework can be further utilized to carry out, for instance, performance prediction and analysis, health condition monitoring, etc. Finally, a grey-box modeling is proposed to analyze the forces, particularly in cross-country skiing races, by combining a deterministic kinetic model with Gaussian process.

Muhammad Touqir Pasha, "All-Digital PWM Transmitters", Linköping Studies in Science and Technology. Dissertations, No. 1972, 2019.
Electronic devices with wireless connectivity are fast becoming a part of daily life. According to some estimates, in the next five years, 10 billion new devices with internet connectivity would be produced. To lower the costs and extend the battery life of electronic circuits, there is an increased interest in using lowcost, low-power CMOS circuits. By taking advantage of the higher integration capabilities of modern CMOS, the analog, digital, and radio circuits can be integrated on a single die, typically called a radio-frequency system-on-chip (RF-SoC).
In an RF-SoC, most of the power is usually consumed by the radio circuits, especially the power amplifier (PA). Hence, to take advantage of the improved switching capability of transistors in modern CMOS, the use of switch-mode PAs (SMPAs) is becoming more popular. SMPAs exhibit a much higher efficiency as compared to their linear counterparts and can be easily integrated with the digital baseband circuits.
To satisfy the demand for higher data throughput, modern wireless standards like LTE and IEEE 802.11 generate envelope-varying signals using advanced modulation schemes like M-QAM and OFDM. Among several other techniques, pulse-width modulation (PWM) allows for the amplification of the envelopevarying signals using SMPAs.
The first part of this thesis explores techniques to improve the spectral performance of PWM-based transmitters. The proposed transmitters are fully digital, and the entire signal chain up to the PA can be implemented using the digital design flow, which is especially beneficial in sub-micron CMOS processes with low voltage headroom. A new transmitter is proposed that compensates for the aliasing distortion in polar PWM transmitters by using outphasing. The transmitter exhibits an improvement of up to 9 dB in dynamic range for a 1.4 MHz LTE uplink signal. The idea is extended to compensate for both image and aliasing distortions in all-digital implementations of polar PWM transmitters. By using a field programmable gate array (FPGA) and Class-D SMPAs, the proposed transmitter shows an improvement of up to 6.9 dBc in the adjacent channel leakage ratio (ACLR) and 10% in the error vector magnitude (EVM) for a 20 MHz LTE uplink signal. The proposed transmitter is fully programmable and can be easily adapted for multi-band and multi-standard transmission.
To enhance the phase linearity of all-digital PWM transmitters, a new transmitter architecture based on outphasing is presented. The proposed transmitter uses outphasing to improve the phase resolution and exhibits an improvement of 2.8 dBc and 3.3% in ACLR and EVM, respectively.
The difference between the polar and quadrature implementations of RFPWM based transmitters is explored. By using mathematical derivations and simulations, it is shown that the polar implementation outperforms the quadrature implementation due to the lower quantization noise. An RF-PWM based transmitter that eliminates both image and aliasing distortions is presented. The proposed transmitter has an all-digital implementation, uses a single SMPA, and eliminates the need for a power combiner resulting in a more compact design. For a 1.4 MHz LTE uplink signal, the proposed transmitter exhibits an improvement of up to 11.3 dBc in ACLR.
The second part of this work focuses on the design of all-digital area-efficient architectures of time-to-digital converters (TDCs). A TDC is essentially a stopwatch with a pico-second resolution and can be used to accurately quantify the pulse width and position of PWM signals.
A Vernier delay line-based TDC is presented that replaces the conventionally used sampling D flip-flops by a single transistor. This resulting implementation does not suffer from blackout time associated with D flip-flops allowing for a more compact design. The proposed TDC achieves a time resolution of 5.7 ps, and consumes 1.85 mW of power while operating at 50 MS/s.
A modified switching scheme to reduce the power consumed by the thermometerto- binary encoder used in the TDCs is presented. By taking advantage of the operating nature of the TDCs, the proposed switching scheme reduces the power consumption by up to 40% for a 256-bit encoder.

Ylva Jung, "Inverse system identification with applications in predistortion", Linköping Studies in Science and Technology. Dissertations, No. 1966, 2018.
Models are commonly used to simulate events and processes, and can be constructed from measured data using system identification. The common way is to model the system from input to output, but in this thesis we want to obtain the inverse of the system.
Power amplifiers (PAs) used in communication devices can be nonlinear, and this causes interference in adjacent transmitting channels. A prefilter, called predistorter, can be used to invert the effects of the PA, such that the combination of predistorter and PA reconstructs an amplified version of the input signal. In this thesis, the predistortion problem has been investigated for outphasing power amplifiers, where the input signal is decomposed into two branches that are amplified separately by highly efficient nonlinear amplifiers and then recombined. We have formulated a model structure describing the imperfections in an outphasing \abbrPA and the matching ideal predistorter. The predistorter can be estimated from measured data in different ways. Here, the initially nonconvex optimization problem has been developed into a convex problem. The predistorters have been evaluated in measurements.
The goal with the inverse models in this thesis is to use them in cascade with the systems to reconstruct the original input. It is shown that the problems of identifying a model of a preinverse and a postinverse are fundamentally different. It turns out that the true inverse is not necessarily the best one when noise is present, and that other models and structures can lead to better inversion results.
To construct a predistorter (for a PA, for example), a model of the inverse is used, and different methods can be used for the estimation. One common method is to estimate a postinverse, and then using it as a preinverse, making it straightforward to try out different model structures. Another is to construct a model of the system and then use it to estimate a preinverse in a second step. This method identifies the inverse in the setup it will be used, but leads to a complicated optimization problem. A third option is to model the forward system and then invert it. This method can be understood using standard identification theory in contrast to the ones above, but the model is tuned for the forward system, not the inverse. Models obtained using the various methods capture different properties of the system, and a more detailed analysis of the methods is presented for linear time-invariant systems and linear approximations of block-oriented systems. The theory is also illustrated in examples.
When a preinverse is used, the input to the system will be changed, and typically the input data will be different than the original input. This is why the estimation of preinverses is more complicated than for postinverses, and one set of experimental data is not enough. Here, we have shown that identifying a preinverse in series with the system in repeated experiments can improve the inversion performance.

Christian Andersson Naesseth, "Machine learning using approximate inference: Variational and sequential Monte Carlo methods", Linköping Studies in Science and Technology. Dissertations, No. 1969, 2018.
Automatic decision making and pattern recognition under uncertainty are difficult tasks that are ubiquitous in our everyday life. The systems we design, and technology we develop, requires us to coherently represent and work with uncertainty in data. Probabilistic models and probabilistic inference gives us a powerful framework for solving this problem. Using this framework, while enticing, results in difficult-to-compute integrals and probabilities when conditioning on the observed data. This means we have a need for approximate inference, methods that solves the problem approximately using a systematic approach. In this thesis we develop new methods for efficient approximate inference in probabilistic models.
There are generally two approaches to approximate inference, variational methods and Monte Carlo methods. In Monte Carlo methods we use a large number of random samples to approximate the integral of interest. With variational methods, on the other hand, we turn the integration problem into that of an optimization problem. We develop algorithms of both types and bridge the gap between them.
First, we present a self-contained tutorial to the popular sequential Monte Carlo (SMC) class of methods. Next, we propose new algorithms and applications based on SMC for approximate inference in probabilistic graphical models. We derive nested sequential Monte Carlo, a new algorithm particularly well suited for inference in a large class of high-dimensional probabilistic models. Then, inspired by similar ideas we derive interacting particle Markov chain Monte Carlo to make use of parallelization to speed up approximate inference for universal probabilistic programming languages. After that, we show how we can make use of the rejection sampling process when generating gamma distributed random variables to speed up variational inference. Finally, we bridge the gap between SMC and variational methods by developing variational sequential Monte Carlo, a new flexible family of variational approximations.

Target tracking is a mature topic with over half a century of mainly military and aviation research. The field has lately expanded into a range of civilian applications due to the development of cheap sensors and improved computational power. With the rise of new applications, new challenges emerge, and with better hardware there is an opportunity to employ more elaborated algorithms.
There are five main contributions to the field of target tracking in this thesis. Contributions I-IV concern the development of non-conventional models for target tracking and the resulting estimation methods. Contribution V concerns a reformulation for improved performance. To show the functionality and applicability of the contributions, all proposed methods are applied to and verified on experimental data related to tracking of animals or other objects in nature.
In Contribution I, sparse Gaussian processes are proposed to model behaviours of targets that are caused by influences from the environment, such as wind or obstacles. The influences are learned online as a part of the state estimation using an extended Kalman filter. The method is also adapted to handle time-varying influences and to identify dynamic systems. It is shown to improve accuracy over the nearly constant velocity and acceleration models in simulation. The method is also evaluated in a sea ice tracking application using data from a radar on Svalbard.
In Contribution II, a state-space model is derived that incorporates observations with uncertain timestamps. An example of such observations could be traces left by a target. Estimation accuracy is shown to be better than the alternative of disregarding the observation. The position of an orienteering sprinter is improved using the control points as additional observations.
In Contribution III, targets that are confined to a certain space, such as animals in captivity, are modelled to avoid collision with the boundaries by turning. The proposed model forces the predictions to remain inside the confined space compared to conventional models that may suffer from infeasible predictions. In particular the model improves robustness against occlusions. The model is successfully used to track dolphins in a dolphinarium as they swim in a basin with occluded sections.
In Contribution IV, an extension to the jump Markov model is proposed that incorporates observations of the mode that are state-independent. Normally, the mode is estimated by comparing actual and predicted observations of the state. However, sensor signals may provide additional information directly dependent on the mode. Such information from a video recorded by biologists is used to estimate take-off times and directions of birds captured in circular cages. The method is shown to compare well with a more time-consuming manual method.
In Contribution V, a reformulation of the labelled multi-Bernoulli filter is used to exploit a structure of the algorithm to attain a more efficient implementation.Modern target tracking algorithms are often very demanding, so sound approximations and clever implementations are needed to obtain reasonable computational performance. The filter is integrated in a full framework for tracking sea ice, from pre-processing to presentation of results.

Marcus Karlsson, "Blind Massive MIMO Base Stations: Downlink Transmission and Jamming", Linköping Studies in Science and Technology. Dissertations, No. 1950, 2018.
Massive MIMO (Multiple-Input--Multiple-Output) is a cellular-network technology in which the base station is equipped with a large number of antennas and aims to serve several different users simultaneously, on the same frequency resource through spatial multiplexing. This is made possible by employing efficient beamforming, based on channel estimates acquired from uplink reference signals, where the base station can transmit the signals in such a way that they add up constructively at the users and destructively elsewhere. The multiplexing together with the array gain from the beamforming can increase the spectral efficiency over contemporary systems.
One challenge of practical importance is how to transmit data in the downlink when no channel state information is available. When a user initially joins the network, prior to transmitting uplink reference signals that enable beamforming, it needs system information---instructions on how to properly function within the network. It is transmission of system information that is the main focus of this thesis. In particular, the thesis analyzes how the reliability of the transmission of system information depends on the available amount of diversity. It is shown how downlink reference signals, space-time block codes, and power allocation can be used to improve the reliability of this transmission.
In order to estimate the uplink and downlink channels from uplink reference signals, which is imperative to ensure scalability in the number of base station antennas, massive MIMO relies on channel reciprocity. This thesis shows that the principles of channel reciprocity can also be exploited by a jammer, a malicious transmitter, aiming to disrupt legitimate communication between two single-antenna devices. A heuristic scheme is proposed in which the jammer estimates the channel to a target device blindly, without any knowledge of the transmitted legitimate signals, and subsequently beamforms noise towards the target. Under the same power constraint, the proposed jammer can disrupt the legitimate link more effectively than a conventional omnidirectional jammer in many cases.

Hannes Ovrén, "Continuous Models for Cameras and Inertial Sensors", Linköping Studies in Science and Technology. Dissertations, No. 1951, 2018.
Using images to reconstruct the world in three dimensions is a classical computer vision task. Some examples of applications where this is useful are autonomous mapping and navigation, urban planning, and special effects in movies. One common approach to 3D reconstruction is "structure from motion" where a scene is imaged multiple times from different positions, e.g. by moving the camera. However, in a twist of irony, many structure from motion methods work best when the camera is stationary while the image is captured. This is because the motion of the camera can cause distortions in the image that lead to worse image measurements, and thus a worse reconstruction. One such distortion common to all cameras is motion blur, while another is connected to the use of an electronic rolling shutter. Instead of capturing all pixels of the image at once, a camera with a rolling shutter captures the image row by row. If the camera is moving while the image is captured the rolling shutter causes non-rigid distortions in the image that, unless handled, can severely impact the reconstruction quality.
This thesis studies methods to robustly perform 3D reconstruction in the case of a moving camera. To do so, the proposed methods make use of an inertial measurement unit (IMU). The IMU measures the angular velocities and linear accelerations of the camera, and these can be used to estimate the trajectory of the camera over time. Knowledge of the camera motion can then be used to correct for the distortions caused by the rolling shutter. Another benefit of an IMU is that it can provide measurements also in situations when a camera can not, e.g. because of excessive motion blur, or absence of scene structure.
To use a camera together with an IMU, the camera-IMU system must be jointly calibrated. The relationship between their respective coordinate frames need to be established, and their timings need to be synchronized. This thesis shows how to automatically perform this calibration and synchronization, without requiring e.g. calibration objects or special motion patterns.
In standard structure from motion, the camera trajectory is modeled as discrete poses, with one pose per image. Switching instead to a formulation with a continuous-time camera trajectory provides a natural way to handle rolling shutter distortions, and also to incorporate inertial measurements. To model the continuous-time trajectory, many authors have used splines. The ability for a spline-based trajectory to model the real motion depends on the density of its spline knots. Choosing a too smooth spline results in approximation errors. This thesis proposes a method to estimate the spline approximation error, and use it to better balance camera and IMU measurements, when used in a sensor fusion framework. Also proposed is a way to automatically decide how dense the spline needs to be to achieve a good reconstruction.
Another approach to reconstruct a 3D scene is to use a camera that directly measures depth. Some depth cameras, like the well-known Microsoft Kinect, are susceptible to the same rolling shutter effects as normal cameras. This thesis quantifies the effect of the rolling shutter distortion on 3D reconstruction, depending on the amount of motion. It is also shown that a better 3D model is obtained if the depth images are corrected using inertial measurements.

Martin Danelljan, "Learning Convolution Operators for Visual Tracking", Linköping Studies in Science and Technology. Dissertations, No. 1926, 2018.
Visual tracking is one of the fundamental problems in computer vision. Its numerous applications include robotics, autonomous driving, augmented reality and 3D reconstruction. In essence, visual tracking can be described as the problem of estimating the trajectory of a target in a sequence of images. The target can be any image region or object of interest. While humans excel at this task, requiring little effort to perform accurate and robust visual tracking, it has proven difficult to automate. It has therefore remained one of the most active research topics in computer vision.
In its most general form, no prior knowledge about the object of interest or environment is given, except for the initial target location. This general form of tracking is known as generic visual tracking. The unconstrained nature of this problem makes it particularly difficult, yet applicable to a wider range of scenarios. As no prior knowledge is given, the tracker must learn an appearance model of the target on-the-fly. Cast as a machine learning problem, it imposes several major challenges which are addressed in this thesis.
The main purpose of this thesis is the study and advancement of the, so called, Discriminative Correlation Filter (DCF) framework, as it has shown to be particularly suitable for the tracking application. By utilizing properties of the Fourier transform, a correlation filter is discriminatively learned by efficiently minimizing a least-squares objective. The resulting filter is then applied to a new image in order to estimate the target location.
This thesis contributes to the advancement of the DCF methodology in several aspects. The main contribution regards the learning of the appearance model: First, the problem of updating the appearance model with new training samples is covered. Efficient update rules and numerical solvers are investigated for this task. Second, the periodic assumption induced by the circular convolution in DCF is countered by proposing a spatial regularization component. Third, an adaptive model of the training set is proposed to alleviate the impact of corrupted or mislabeled training samples. Fourth, a continuous-space formulation of the DCF is introduced, enabling the fusion of multiresolution features and sub-pixel accurate predictions. Finally, the problems of computational complexity and overfitting are addressed by investigating dimensionality reduction techniques.
As a second contribution, different feature representations for tracking are investigated. A particular focus is put on the analysis of color features, which had been largely overlooked in prior tracking research. This thesis also studies the use of deep features in DCF-based tracking. While many vision problems have greatly benefited from the advent of deep learning, it has proven difficult to harvest the power of such representations for tracking. In this thesis it is shown that both shallow and deep layers contribute positively. Furthermore, the problem of fusing their complementary properties is investigated.
The final major contribution of this thesis regards the prediction of the target scale. In many applications, it is essential to track the scale, or size, of the target since it is strongly related to the relative distance. A thorough analysis of how to integrate scale estimation into the DCF framework is performed. A one-dimensional scale filter is proposed, enabling efficient and accurate scale estimation.

Alkira is an Aboriginal word for bright and sunny. For many it has come to mean a happy place in the sun.

Remarkable Results, Confidentiality and Dignity
A. Roy DeCaro has tried more than 200 jury trials to verdict during his legal career, first as a prosecutor and now as a civil attorney. He has achieved on behalf of his clients over a dozen verdicts in excess of $1,000,000.00, and two verdicts in excess of $10,000,000.00. So, it is little surprise that Best Lawyers® recognized Mr. DeCaro in 2018 as the "Best Personal Injury Lawyer of the Year" for Philadelphia.
As a prosecutor, he persuaded juries to convict murderers, drug dealers, motorcycle gang members, organized crime figures, corrupt police officers and corrupt public officials. As a civil trial lawyer, Roy has represented those who have been seriously injured or killed by others' negligence, including those injured due to medical error, unsafe products, and negligent drivers.
Roy has consistently been selected to the Super Lawyers list and has been ranked as one of the top 10 lawyers in Pennsylvania on two occasions. He was named by "Lawdragon" Magazine as one of the 500 best lawyers in the United States. Roy has regularly been selected by his peers for inclusion in The Best Lawyers in America©.
He is often asked to mediate and arbitrate cases by plaintiff and defense lawyers. He has been called upon to serve on several Blue Ribbon Panels including panels to recommend institutional changes in the Philadelphia Police Department and the Philadelphia Criminal Court System. He is an adjunct Law Professor at Villanova Law School teaching Evidence.
Roy is a member of the International Academy of Trial Lawyers, the American College of Trial Lawyers and the American Board of Trial Advocates. He is president of the Philadelphia Lawyers Club – an "organization that aids lawyers in distress and promotes civility."

$24,000,000 Confidential Settlement for Construction Site Accident
As the operator of a large piece of construction equipment sat down in the cab, he unintentionally moved the joystick control, causing the boom to swing uncontrollably and knock a piece of equipment onto a young man standing nearby. The worker became a quadriplegic. The Raynes team, led by Roy DeCaro with significant assistance of Dan Bencivenga and Marty Brigham, established that the excavator manufacturer's design violated international safety standards, ignored safety alerts from its country's OSHA, and lacked a commercially available alternate design that would have prevented the injury. After jury selection had been completed, the defendants settled for $24,000,000.00.
$10,250,000 Verdict in Swimming Pool Accident
Richard dove from a wooden deck into a backyard, aboveground swimming pool, not understanding its shallow depth. He struck his head on the bottom and was paralyzed. Raynes McCarty sued the manufacturer of the pool liner on Richard's behalf, because the liner had neither adequate depth markers nor warnings against diving. At trial, Roy DeCaro convinced a federal jury to return a $10,250,000 verdict in favor of our client. In response to the verdict, swimming pool manufacturers improved their warnings about the dangers of diving into these pools.
$5,700,000 Verdict in Fatal Car Crash
Florence Gormley was killed in a car crash when a van driven by a Choice Courier employee skidded into her. Roy DeCaro convinced a federal court jury to award $1.8 million in compensatory damages for this homemaker, even though she had never worked outside of her home. The jury also awarded $3.7 million in punitive damages because the company's vans had bald tires, which it had neither inspected nor corrected.
$3,800,000 Verdict in Delaware County for Failure to Treat Sepsis
Janice died as the result of an overwhelming sepsis infection after being in Riddle Memorial Hospital for 14 hours. Over a seven day jury trial, Roy DeCaro convinced the Delaware County jury that Janice's doctors should have acted more quickly to save her life. The jury awarded $3,800,000 to the family, one of the largest awards ever in this County for medical malpractice.

Treasuring the Immeasurable Work of Mothers
14/01/2020 | Harriet Connor

Unlike many women, I did not have an identity crisis when I became a mother. That's probably because I didn't really have a career to identify with in the first place. I had tallied up seven years of tertiary study and worked a few part-time jobs; but I certainly didn't experience any grief at having to stop work when our first son was born.
I spent the next ten years of life with my centre of gravity at home. We welcomed a second son and then a third into our family: I was busy caring for babies, toddlers and pre-schoolers on repeat.
This year, our youngest son will be getting ready to start school; it will be my final year of having children at home during the week. I can feel an identity crisis looming.
But this year, our youngest son will be getting ready to start school; it will be my final year of having children at home during the week. Now I can feel an identity crisis looming. What will I do once our littlest one goes to school?
Our Grandmothers' Careers
Our modern society has a script for this transition: once all of your children start school, you should get a paid job outside of the home.
But this hasn't always been the script. Neither of my grandmothers ever did a single day's paid work after having children (needless to say, their families were able to survive on one single income). In today's world, that would be incomprehensible: a mother of older children who is not working must be excessively wealthy, lazy or plain unemployable. Our modern economy only values work that is paid; if my grandmothers weren't earning money then their marketable skills must have been lying fallow. What on earth were they doing with their time?
Sadly, one of my grandmothers passed away this year; her funeral was a fitting tribute to a remarkable woman. Although my grandmother never worked, people kept speaking about her "career." Granny was a prodigious writer—of poetry, plays and books. She also ran a theatre in the family's backyard and founded several societies. But my grandmother did all of this without any formal training or payment. Her work emerged organically from her passions and talents; it flowed out from her home to benefit the wider world.
From watching the older ladies in my church, I can tell you what the other women in my grandmother's generation were doing with their "spare" time. They were cultivating gardens and preserving the produce; they were making clothes, quilts and blankets; they were cooking meals to share; they were looking after other people's children; they were teaching children about God in schools and churches; they were running "auxiliary" groups to support local hospitals and other organisations and some of them had paid jobs, nursing and teaching in the community.
In previous generations, mothers stood at the heart of society. They were at the centre of a web of relationships that started with their own families and stretched out into the wider community. Men may have been the "head" of institutions like families, schools and churches, but women were the heart.
In previous generations, mothers stood at the heart of society. They were at the centre of a web of relationships that started with their own families and stretched out into the wider community.
While most mothers were "unemployed" and therefore unpaid, they were busy living out their God-given vocation: their skilled hands were turning God's creation into useful and beautiful things to serve family and neighbour; their love and practical care were knitting together the communities around them. And they did all of this while supporting their husbands and raising their children: motherhood and work have never been mutually exclusive.
Mothers Are Not Interchangeable Workers
Our modern economy sees people as detached, interchangeable individuals with a particular set of saleable skills and functions. But a mother is not just a set of skills: she is an irreplaceable person, bound to particular people in a particular place.
Motherhood makes no sense in our modern economy which severs natural bonds between families and neighbours and replaces them with artificial, commercial relationships between clients and professionals. Why would I care for my children for free when I could earn money caring for other people's children? Why would I volunteer to look after my ageing relatives when I could earn money looking after other people's relations?
Of course, many women manage to do both—to serve the wider community and their family. But we need to ask ourselves: What does our society lose when we outsource a mother's core functions to paid professionals? What do we lose when we insist that a mother leave her network of natural relationships in order to do "real" work for strangers?
The recently televised "Old People's Home for Four-Year Olds" was a social experiment that demonstrated how ongoing relationships between children and the elderly are mutually beneficial. Many people responded to the show by petitioning the government to invest in intergenerational facilities and programs. But this reveals just how much we have been conditioned to expect human relationships to be professional and commercial. We already have an effective and universally-accessible intergenerational institution: it's called the extended family! The first response I had to the show was to take my children to visit my grandparents more regularly.
Theologian Alastair Roberts describes a mother's work like this:
The logic of abstraction and alienation departicularizes us and cuts loose the bonds that bind us to each other, our labour, and our world. However, the work of the mother is invested not merely in the performance of generic service functions for prospective or current economic agents (which she could in theory pay another to perform for her), but in the creation of the world of the home, a world that is unexchangeable, a world that is uniquely hers, a realm of life of which she herself—in her embodied particularity—is the heart and the source … The life that she produces through her maternal labour and love is the life by which her entire household grows. It is also a life that spreads out beyond her household into her wider community and society bringing communion and fruitfulness, as she expresses her distinctively womanly power to make the world into a home.

When Mum Needs a Job
The sad reality is that our modern economy will not validate my unpaid work as a mother: our family will eventually need a second income in order to make ends meet. But how can I find work that honours and grows out of my God-given identity as a mother, rather than competes with it? Here are some ways I have begun to approach it.
Follow the cords of relationship
Firstly, I have started looking to the network of relationships that I already have—in our church, our children's school, our neighbourhood—for work that would strengthen those real and particular communities. To that end, I have started telling people in those networks that I am looking for work in case an opportunity opens up. I know a number of mothers who work with their husbands or other family members, using their skills to add value to the family business. Another friend has decided to cut out the "middle man" and simply home-school her own children!
As I have spoken to other mothers about our shared desire to find family-friendly work, a kind of "mothers' co-op" has developed where we share relevant job opportunities and recommend one another to prospective employers.
But I can see the potential for even greater cooperation: between us we have a small-scale economy just waiting to come to life. You want to take a teaching job at the local school? Let me mind your kids instead of sending them to daycare. Your child wants to learn Spanish? Let me tutor them and you can repay me with piano lessons or cleaning. Your teenage daughter wants some babysitting work? Let her mind my kids while I do some work from home. Let me design and print your party invitations in exchange for some of those handmade earrings etc. etc.
Monetise what you are already doing
I have also been considering whether I could monetise something I am already doing. Some mothers I know have started businesses making clothes or other products from home; others have commercialised their work in the kitchen, selling family meals or allergy-friendly snacks; others provide training or tutoring in a particular skill; and some mothers use their creative talents with words or images to earn money.
Do it from home
Working from home can provide a more family-friendly option. For example, a friend of mine is a hairdresser; but rather than work in a commercial hair salon and pay someone else to mind her children, she has set up a small salon in her garage. Now she earns an income by serving her friends and neighbours, while her children (and theirs!) can play just outside the door.
Start as a volunteer
While a second income would ease the pinch of having a family budget that is stretched to its limit, I have started seeing the question of payment as secondary in my search for meaningful work.
We all have to grapple with the fact that there is a significant difference between a job and a vocation. A job may pay the bills, but it won't necessarily help me to live out my God-given calling to use my talents to serve the communities I belong to. A vocation, however, will be immeasurably valuable, meaningful and satisfying, but it may never pay the bills. How blessed are those who have found a way to combine the two!
My "Job" Offer
At the end of last year, I was asked to take over the running of a lunchtime Christian group at our children's school. One hour before I was due to give my answer, our youngest son was unexpectedly offered an extra day at preschool—the very day the group takes place. I took that as a sign from God and agreed to take it on.
Since then, the school's leadership has expressed their gratitude and enthusiasm, even announcing my new role on Speech Day.
I'm as excited about this volunteer work as I would have been about a paid job. It has provided me with a precious opportunity to use my gifts to serve our school community for the glory of God.
It sounds strange to say it, but I think I'm as excited about this volunteer work as I would have been about a paid job. The work may not be paid, but it has provided me with a precious opportunity to use my gifts to serve our school community for the glory of God. And who knows—maybe one day it will lead to a paid role at the school.
I suspect that I will never have a "career" in the modern sense; but if my contribution to the world looks anything like my grandmothers', then I will be very proud.

Do you have any ideas for the wall that faces the door of your bedroom? How about decorating it with a world map wallpaper, scenes from nature or a geometric pattern? Wallpapers and decals are one of the most economical ways to give your bedroom a brand new look. Plus, they're easily available because many stores sell online wallpaper in Australia. Browse their collection, choose your favorite design, pay for it, and wait for the product to be delivered to your doorstep.
And the best part about ordering online wallpaper in Australia is that you get to apply them yourself!
Which colors are the most prominent in your bedroom? Yes, bold colors are in these days, but how about going for soothing, subtle shades? They have a charm of their own, and they are so easy on the eye. Are you aware of the color theory? Blue, green and lavender hues are considered to be serene. Tones like browns, pomegranates, and topaz introduce a sense of coziness, making the space comfortable and relaxing. Pale pinks and peaches add soft, romantic vibes.
Select your favorite shades and brush them here and there in the bedroom. So, for instance, if you decide to have world map wallpaper on one wall, then you can brush pale blue or aqua shades on the rest of the walls. And by the way, you can also display colors in the form of cushions, small decorative items or even a wail painting.
While subtle shades are one of the best bedroom decorating trends, don't overdo and throw in too many colors all at once. At most, there should only be three main shades in any room.
4. Don't Ignore the Ceiling, Please!
A bland and dull ceiling is so boring, especially when you lie down on the bed. While something dark above may make space look smaller and uninviting, you can always have something soft up there. So instead of the traditional blank ceiling, how about a patterned one? Or maybe, you could stick to a plain ceiling, but choose a hue that is a lighter version of the wall. This should make your bedroom look more comfortable and intimate.
Ceilings can be decorated in other ways as well— through ceiling wallpapers, beams, moldings, and chandeliers.
Don't go for too many window treatments, especially if your bedroom is small. Limit them so that your windows draw in the maximum amount of light. Want privacy? Install blinds in the form of hanging panels or rollers – these are the most preferred.
If your bedroom is small, you would want to get as much storage as you can. Fitted floor-to-ceiling units maximize space and offer more storage in clever ways. Featuring drawers for personal belongings, shelves for books and flat surfaces that work great as laptop tables, these units can be used in an array of ways. And some of them may even have a built-in wardrobe on one side.
Storage under the bed is another great idea. Some of the beds are already equipped with drawers, but if that's not the case, you can always keep boxes or bags that can slide underneath. Do conceal them with beautiful bed skirts, though, so that your room looks neat and clean.
Set up a quiet corner in the room, preferably near a window, where you can relax or read in peace. Place a comfy chair, a footstool or even a bean bag. If you have space, keep some cushions as well for greater comfort. And when there's enough room, set up a window seat – which is an all-time favorite trend.
Dress up your room in soft linen fabrics, adding more depth to space. Purchase sheets that are 100% linen or cotton with thread count greater than 350. Choose them in the same shades as the walls and the rest of the decor to complete the picture.
Trendy bedrooms feature a number of lighting options. The traditional fixtures bathe the entire room in a comfortable glow. Small lamps should be placed for reading purposes and similar activities. Accent light fixtures illuminate the walls softly. Bedside lamps are also a good option, but choose products with a separate power switch and dimmer so that you can adjust the light as required.
Got a sleek hardwood floor? How about lining the bed against the wall to draw more attention to the floor? But to maximize impact, avoid a bulky bed frame.
Mirrors make any space look bigger than it actually is. Though they are available with vintage frames as well, choose simple, modern frames if you want to give your room an edgy look.
Which of the above-mentioned ideas have you liked the most so far? We'd like to close off with one final point. Regardless of what colors or decorations you choose, stick to simplicity and elegance. Make sure that there is enough distance between furniture pieces, at least two feet between the beds, dressers, and tables. Keep accessories to a minimum—a beautiful artwork piece, some photos, candles, and flowers are enough. Throw some pillows and cushions and pillows on the bed, a rug on the floor, and that's it!
The more minimal your bedroom is, the more amazing it would look! Have fun decorating your own personal resort!
