16. Electrical bioimpedance cerebral monitoring
Sammanfattning : Neurologically related injuries cause a similar number of deaths as cancer, and brain damage is the second commonest cause of death in the world and probably the leading cause of permanent disability. The devastating effects of most cases of brain damage could be avoided if it were detected and medical treatment initiated in time. LÄS MER
17. Dielectric properties of poly(ethyelene-co-butyl acrylate) filled with Alumina nanoparticles
Sammanfattning : In this work dielectric properties of the poly(ethylene-co-butyl acrylate)filled with alumina nanoparticles are evaluated. These nanocomposite materialswere manufactured at the department of Fibre and Polymer Technology,KTH.This study is limited to the properties of general importance for the AC applications. LÄS MER
18. Electrical Bioimpedance Cerebral Monitoring : From Hypothesis and Simulation to First Experimental Evidence in Stroke Patients
Sammanfattning : Stroke is amongthe leading causes of death worldwide and requires immediate care to prevent death or permanent disability. Unfortunately, the current stateof stroke diagnosis is limited to fixed neuroimaging facilities that do not allow rapid stroke diagnosis. LÄS MER
19. Electronic Properties of Diamond
Sammanfattning : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties compared to other (wide bandgap) semiconductors make it desirable to develop single-crystalline epitaxial diamond films for many electronic device and detector applications.

20. Electrical properties of polycrystalline silicon
Sammanfattning : Polysilicon is used, among other materials, in today's integrated circuits. In this thesis, the structural and electrical properties' of polysilicon thin film resistors have been studied. The aim has been to improve the long-term stability and increase the knowledge concerning grain-boundary related phenomena. LÄS MER
