1. The impact of railway vibration and noise on sleep
Sammanfattning : Sleep is a vital component of good health, and sleep loss is associated with impaired cognition, decreased psychomotor performance, cardiovascular disease, adverse effects on endocrine and metabolic function, negative mood, impaired memory, and more. A growing burden of freight transportation on global railway networks will likely lead to an increase in nocturnal vibration and noise at nearby dwellings. LÄS MER
2. Detection in Digital Communication Systems with Phase Noise
Sammanfattning : In every communication system, the limitations of the hardware sets a constraint on the overall system performance. More often than not, these limitations are not taken into account during the system design stage where the hardware is considered ideal. LÄS MER
3. On weak and strong convergence of numerical approximations of stochastic partial differential equations
Sammanfattning : This thesis is concerned with numerical approximation of linear stochastic partial differential equations driven by additive noise. In the first part, we develop a framework for the analysis of weak convergence and within this framework we analyze the stochastic heat equation, the stochastic wave equation, and the linearized stochastic Cahn-Hilliard, or the linearized Cahn-Hilliard-Cook equation.

4. Traffic noise and property values
Sammanfattning : This thesis consists of five papers about traffic noise andproperty values. Their aim was to analyze the impact of trafficnoise on property values and to translate this effect into amonetary value. The method used was the hedonic technique inwhich the price of the property is assumed to be a function ofits attributes (e.g. LÄS MER
5. The Finite Element Method for Fractional Order Viscoelasticity and the Stochastic Wave Equation
Sammanfattning : This thesis can be considered as two parts. In the first part a hyperbolic type integro-differential equation with weakly singular kernel is considered, which is a model for dynamic fractional order viscoelasticity. In the second part, the finite element approximation of the linear stochastic wave equation is studied. LÄS MER
