16. Learning Stochastic Nonlinear Dynamical Systems Using Non-stationary Linear Predictors
Sammanfattning : The estimation problem of stochastic nonlinear parametric models is recognized to be very challenging due to the intractability of the likelihood function. Recently, several methods have been developed to approximate the maximum likelihood estimator and the optimal mean-square error predictor using Monte Carlo methods. LÄS MER
17. Models for capturing the penetration of a diffusant concentration into rubber : Numerical analysis and simulation
Sammanfattning : Understanding the transport of diffusants into rubber plays an important role in forecasting the material's durability. In this regard, we study different models, conduct numerical analysis, and present simulation results that predict the evolution of the penetration front of diffusants. LÄS MER
18. Fast Numerical Techniques for Electromagnetic Problems in Frequency Domain
Sammanfattning : The Method of Moments is a numerical technique for solving electromagnetic problems with integral equations. The method discretizes a surface in three dimensions, which reduces the dimension of the problem with one. A drawback of the method is that it yields a dense system of linear equations. LÄS MER
19. Aspects on Interference and Diversity in Wireless Networks
Sammanfattning : This thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. LÄS MER
