I have a tibial stress fracture from running and was told to use crutches for three weeks. In general, is this really necessary once the pain has subsided (as it has, in my case). Feels silly to use crutches when nothing hurts.
An artificial neuron network (ANN) is a computational model based on the structure and functions of biological neural networks. Information that flows through the network affects the structure of the ANN because a neural network changes - or learns, in a sense - based on that input and output. ANNs are considered nonlinear statistical data modeling tools where the complex relationships between inputs and outputs are modeled or patterns are found.
An annuity is a series of payments made at equal intervals. Examples of annuities are regular deposits to a savings account, monthly home mortgage payments, monthly insurance payments and pension payments. Annuities can be classified by the frequency of payment dates. The payments may be made weekly, monthly, quarterly, yearly, or at any other regular interval of time. An annuity which provides for payments for the remainder of a person's lifetime is a life annuity.
