2. 1. Moisture and Chloride Transport in Concrete

   Author : Filip Nilenius; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale modelling; mass transport; coupled diffusion; statistical volume element; interfacial transition zone.; computational homogenization; mesoscale;

   Abstract : 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. READ MORE

4. 2. Mechanical behavior of Lithium-ion battery electrodes – experimental and statistical finite element analyses

   Author : İbrahim Buğra Üçel; Peter Gudmundson; Ralf Jänicke; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion batteries; mechanical testing; statistics; finite elements; electrodes; Solid Mechanics; Hållfasthetslära;

   Abstract : 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. READ MORE

5. 3. Thermocoagulation in Deep Brain Structures : Modelling, simulation and experimental study of radio-frequency lesioning

   Author : Johannes Johansson; Karin Wårdel; Stefan Andersson-Engels; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosurgery; Radiofrequency ablation; Finite element method; Blood perfusion; Cerebrospinal fluid; Free convection; Neurosurgery; Neurokirurgi;

   Abstract : 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. READ MORE

6. 4. Factors Associated with Motorcylists' Safety at Access Points along Primary Roads in Malaysia

   Author : Marizwan Manan; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; access point; primary road; motorcyclists’ behavior; Safety Performance function; Motorcycle accident fatality;

   Abstract : 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. READ MORE

7. 5. On computational homogenization of fracturing continua

   Author : Erik Svenning; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Weak periodicity; Computational Homogenization; Crack propagation; XFEM;

   Abstract : 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. READ MORE
