Sammanfattning : Effective and efficient product development is critical to business success on the increasingly competitive global market, and simulation has proven to support this in many sectors. The aim of this thesis is to study how properties of complex mechanical and mechatronic systems can be more efficiently and systematically predicted, described, assessed and improved in product development.

2. Feasibility and efficacy of incorporating an exoskeleton in gait training during subacute stroke rehabilitation
Sammanfattning : Introduction: Hemiparesis is the most common acute manifestation of stroke and often has a strong negative impact on walking ability leaving one third of patients dependent in walking activities outside one’s home. Improved methods for training of gait during stroke rehabilitation could tackle the challenge of achieving independent walking and promote better outcomes. LÄS MER
Sammanfattning : Numerical simulations have been done with the CHEMKINsoftware to study different aspects of wall effects in thecombustion of lean, laminar and premixed flames in anaxisymmetric boundary-layer flow. The importance of the chemical wall effects compared to thethermal wall effects caused by the development of the thermaland velocity boundary layer has been investigated in thereaction zone by using different wall boundary conditions, walltemperatures and fuel/air ratios.

Sammanfattning : Europe’s first national parks were established in northern Sweden in 1909 and this region has thus functioned as a protected and aesthetic pleasure landscape for a century. In 1996, due to the combination of spectacular natural environment and ancient Sami traditions the Laponian World Heritage Area was established here. LÄS MER
5. Understanding and managing cardiovascular disease risk factors in Vietnam : integrating clinical and public health perspectives
Sammanfattning : Background: Vietnam, like other low-income countries, is facing an epidemic burden of cardiovascular disease risk factors (CVDRFs). The magnitude and directions of CVDRF progression are matters of uncertainty. LÄS MER
