An active defense against an incoming missile requires information of it, including a guidance law parameter and first-order lateral time constant. To this end, assuming that with proportional navigation (PN) attempts to attack aerial target bang-bang evasive maneuvers, identification model based on the gated recurrent unit (GRU) neural network is built in paper. The analytic solutions for cons...

conclusions the use of smoothing methods helps us to eliminate non-linear effects but it is more appropriate to use cox proportional hazards model in medical data because of its’ ease of interpretation and capability of modeling both continuous and discrete covariates. also, cox proportional hazards model and smoothing methods analysis identified that age at diagnosis and tumor size were indepe...

This paper proposes an impact time control guidance law based on exact nonlinear kinematics equations. To address the problem of providing enhanced intercept accuracy, we formulated error variable whose regulation ensures fulfillment required tasks without time-to-go estimation. Based Lyapunov stability theory, a desired line-of-sight rate profile that satisfies convergence was constructed, fro...

We consider the following problem in which a given number of items has to be chosen from a predefined set. Each item is described by a vector of attributes and for each attribute there is a desired distribution that the selected set should have. We look for a set that fits as much as possible the desired distributions on all attributes. Examples of applications include choosing members of a rep...
