21. Always on the wing - Fluid dynamics, flight performance and flight behavior of common swifts
Sammanfattning : The aerodynamics and kinematics behind the flight of animals are relatively unknown. Although animal flight has been studied for several hundreds of years, it is only in recent time that we have the technical abilities to study the mechanistic basis of animal flight. LÄS MER
22. Shoulder Kinematics and Impingement. Dynamic Radiostereometric analysis of the shoulder
Sammanfattning : Abstract This study aimed to evaluate the three-dimensional kinematics of the shoulder joint in patients with shoulder impingement and controls with focus on three well known diagnostic tests; painful arc test (active abduction), Neer sign (passive elevation) and Hawkins sign. The shoulder rhythm, the speed of motion and if successful treatment of impingement could be associated with changes of the shoulder kinematics were studied Dynamic radiostereometry (RSA) is feasible method to study rotations and translations of the gleonohumeral joint because of its high precision.

23. Seated postural reactions to mechanical shocks : laboratory studies with relevance for risk assessment and prevention of musculoskeletal disorders among drivers
Sammanfattning : Professional drivers of off-road vehicles, driving on irregular terrain such as in forestry, agriculture and mining, are exposed to whole-body vibration and mechanical shocks. These driver groups have reported severe musculoskeletal problems in the spine, but the association to seated postural reactions is not fully understood. LÄS MER
24. Knee function, knee proprioception and related brain activity following anterior cruciate ligament injury
Sammanfattning : Background: Injury of the anterior cruciate ligament (ACL) may have negative effects on the short- and long-term function and proprioception of the knee joint. However, existing tests of knee function are often sports-related and less relevant for assessment in the very long term and there remains no ‘gold standard’ test of knee proprioception. LÄS MER
25. Toward a Sustainable Human-Robot Collaborative Production Environment
Sammanfattning : This PhD study aimed to address the sustainability issues of the robotic systems from the environmental and social aspects. During the research, three approaches were developed: the first one an online programming-free model-driven system that utilises web-based distributed human-robot collaboration architecture to perform distant assembly operations.
