26. Feasible Direction Methods for Constrained Nonlinear Optimization : Suggestions for Improvements
Sammanfattning : This thesis concerns the development of novel feasible direction type algorithms for constrained nonlinear optimization. The new algorithms are based upon enhancements of the search direction determination and the line search steps. LÄS MER
27. Road Surface and Tyre Interaction : Functional Properties affecting Road Dust Load Dynamics and Storage
Sammanfattning : Luftburna partiklar (PM) är ett problem för människans hälsa, där flertalet samband mellan negativa hälsoeffekter finns mellan luftföroreningar finns, bland annat för respiratoriska sjukdomar, lungcancer och kardiovaskulära sjukdomar med flera. I länder där dubbdäck används, till exempel Sverige, Finland och Norge, och sandning av vägar och gator genomförs vintertid för att säkerställa god friktion kommer en betydande andel av partiklarna från vägslitage och nedkrossning av sand vilket bidrar till PM10.

28. Excess pore water pressure generation in fine granular materials under cyclic loading -A laboratory study
Sammanfattning : Abstract Excess pore water pressure can be generated in subgrades of both railway and pavement sub-structures under cyclic loading caused by heavy traffic. When saturated subgrades are subjected to cyclic loading, excess pore water pressures accumulate over time which then could lead to migration of particles into overlying layers. LÄS MER
29. Contact stiffness in tyre/road noise modelling and speed dependencies of tyre/road noise generation mechanisms
Sammanfattning : Tools for simulating tyre/road noise are highly valuable in the efforts to limit the negative consequences of road traffic noise.A numerical tyre/road noise simulation tool was in this study used to investigate how the contact stiffness parameter affects the predicted tyre/road noise.

30. On the performance of transmitting IP traffic over a shared cellular radio channel with a central scheduling mechanism
Sammanfattning : This thesis focuses on the performance of sending IP traffic over a shared cellular radio channel with a central scheduling mechanism. Using a shared channel for IP traffic increases the channel utilisation compared to using dedicated channels. LÄS MER
