Lehane, Barry, Professor Co-supervisors: Dyskin, Arcady, Prof; Ash, Steve, Mr (Lycopodium) Calibration of Real World Dynamic Foundation Models Disciplines: Civil The design of dynamically loaded foundation is an important of heavy industry projects. Such foundations differ from other foundations in that they can exhibit resonant behaviour under working conditions. Damping is a key parameter in assessment of resonant behaviour. Damping is influenced by the behaviour of both the soil and concrete. Classical methods are able to develop closed form solutions for infinitely rigid foundations (refer Barkan’s equations) with the energy dissipating into soil providing the primary form of damping. Other solutions exist for flexible foundations where bending, warping and twisting of the concrete is the primary mode of damping. In real world foundations damping in soil and damping in concrete both contribute to actual behaviour. When both concrete and soil provide significant damping, the solution is not well understood within the industry. This project will work with industry to compare current Finite Elements methods against experimental data - to be obtained by the student with the aim of calibrating industry models and provide recommendations for development of future models where concrete and soil damping are both significant Lei, Wen, Professor Semiconductor Nanosensors Disciplines: Electrical & Electronic, Materials Semiconductor nanostructures are semiconductor materials of nanoscale dimensions, including zero-, one-, and two-dimensional nanostructures. They have many unique properties such as large surface area-to-volume ratio, very high aspect ratio, and strong quantum confinement including both carrier and photon. This leads to many unique and desirable electronic and optical properties for semiconductor nanostructures and thus various novel devices with superior performance over existing devices to revolutionise our technological world. These nanodevices include transistors, light emitters, solar cells, and sensors that are used in our daily life such as mobile phones, large-area displays, solar panels, and telecommunication systems. Apart from their super performance, these nanodevices present other advantages such as smaller size, lower cost, and higher energy efficiency, compared to traditional semiconductor devices with larger dimensions. In this project, we will focus on the development of one- and/or two-dimensional semiconductor nanosensors with numerous potential applications ranging from light sensing, to environment sensing, and to telecommunication.
