1. Moisture and Chloride Transport in Concrete
Sammanfattning : Material properties pertaining to the physical phenomena of mass transport in concrete are important for the durability of concrete structures, and they can ultimately be derived from material heterogeneities found at different subscales. On the mesoscale level, these heterogeneities are mainly characterized by the presence of embedded aggregates in the cement paste, together with cracks. LÄS MER
2. Mechanical behavior of Lithium-ion battery electrodes – experimental and statistical finite element analyses
Sammanfattning : The applications of Li-ion batteries in the electronics and vehicle industry is increasing at a very rapid pace. This is primarily due to superior properties such as high specific energy storage and power as well as wider operation temperature ranges. LÄS MER
3. Thermocoagulation in Deep Brain Structures : Modelling, simulation and experimental study of radio-frequency lesioning
Sammanfattning : Radio-frequency (RF) lesioning is a method utilising high frequency currents for thermal coagulation of pathological tissue or signal pathways. The current is delivered from an electrode with a temperature sensor, permitting control of the current at a desired target temperature. In the brain RF-lesioning can e.g. LÄS MER
4. Factors Associated with Motorcylists' Safety at Access Points along Primary Roads in Malaysia
Sammanfattning : More than 50% of road accident fatality victims in Malaysia are motorcyclists, numbering more than 4,000 fatalities per year. The aim of this thesis is to investigate motorcyclists’ road safety problems in general in Malaysia, and narrow down the focus to the most salient road infrastructure related risk factors. LÄS MER
5. On computational homogenization of fracturing continua
Sammanfattning : Ductile fracture is important to control in many industrial processes, be it a desired phenomenon (e.g. in metal cutting) or a failure to be prevented (e.g. LÄS MER
