21. Modelling, Simulaltion, and Visualization of Deep Brain Stimulation
Sammanfattning : Deep brain stimulation (DBS) is an effective surgical treatment for neurological diseases such as essential tremor, Parkinsonʹs disease (PD) and dystonia. DBS has so far been used in more than 70 000 patients with movement disorders, and is currently in trial for intractable Gilles de la Tourette’s syndrome, obsessive compulsive disorders, depression, and epilepsy.

22. On the nature and etiology of chronic achilles tendinopathy
Sammanfattning : The present studies included 362 consecutive patients and 147 healthy controls and were conducted to provide a rational basis for treatment and future research. The major lesion was a focal non-inflammatory tendon degeneration (tendinosis). Twenty per cent of the cases were complicated by a secondary partial rupture. The paratenon was normal. LÄS MER
23. Prognosis in acute myeloid leukemia and influence of monocytic markers : epidemiological, clinical and experimental studies
Sammanfattning : The aim of the first part of this thesis was to describe an unselected series of AML patients in adults ( > 15 years) from the three counties Orebro, Värmland and Södermanland 1987-1992, including cases un-referred from district hospitals. In the study of incidence and registration, also ALL and unspecified AL were included due to delimitation difficulties. LÄS MER
24. Custom Datapaths for DSP ASICs Methodology and Implementation
Sammanfattning : This thesis regards datapath design and analysis at several abstraction levels. Five papers are presented that focus on datapath design for mobile communication systems and design methodologies for such datapaths. Paper I discusses different aspects of Turbo channel decoder design for high speed and low power applications. LÄS MER
25. Simulation methodologies within virtual manufacturing applied on mechanical cutting
Sammanfattning : Virtual manufacturing, that is, simulation of welding, heat treatment, cutting and other manufacturing processes is becoming more and more used as a tool for prediction of material- and mechanical properties in modern industry. By simulations we refer in this case to FE-simulations of the thermo-mechanical effect of the manufacturing process on the component in question. LÄS MER
