The present article is a translation—to Farsi—of an article by Dr. Ali Mirchi (postdoctoral research associate at the Department of Civil and Environmental Engineering, Michigan Technological University), Dr. Kaveh Madani (lecturer in Environmental Management at the Centre for Environmental Policy, Imperial College London) and Dr. Amir Aghakouchak (assistant professor at the Department of Civil an
A time domain method building on the concept of wave splitting is used to study direct wave propagation phenomena in weakly nonlinear media. The starting point is the linear wave equation with time-dependent coefficients. This means that the studied nonlinear medium in some sense has to be approximated with a nonstationary medium which changes while the wave passes through. For the nonstationary e
An experimental approach to verify the forward scattering sum rule for periodic structures is presented. This approach allows an upper bound on the total cross section integrated over a bandwidth from a simple static problem to be found. Based on energy conservation, the optical theorem is used to construct a relation between the total cross section and the forward scattering of periodic structure
In this thesis, collective collapse in basketball is investigated. Although experienced by most team sport players, the phenomenon still puzzles the world of sports. Collective collapse is described as a sudden decrease in performance quality by a sport team, often with a devastating effect on the game outcome. The condition implies a social process, i.e. there is an impact on a majority of the t
A good quality of life (QoL) can be regarded as the ultimate goal of psychiatric treatment and rehabilitation. The objective of the present thesis was to study the how the QoL of patients with schizophrenia was related to their social functions and varying social environments. Psychiatric services have undergone major changes in the last 50 years, from an asylum-based model to community psychiatry
