1. First-Principles Studies of Materials Properties : Pressure-Induced Phase Transitions & Functional Materials
Sammanfattning : This thesis presents the first-principles studies of materials properties within the framework of the density functional theory (DFT). The thesis constitutes three main parts, i. e., pressure-induced phase transitions in solids, data-storage and clean-energy materials. LÄS MER
Sammanfattning : The search for alternate and renewable energy resources as well as the efficient use of energy and development of such systems that can help to save the energy consumption is needed because of exponential growth in world population, limited conventional fossil fuel resources, and to meet the increasing demand of clean and environment friendly substitutes. Hydrogen being the simplest, most abundant and clean energy carrier has the potential to fulfill some of these requirements provided the development of efficient, safe and durable systems for its production, storage and usage.

Sammanfattning : The number of concurrently executing processes and their memory demandin multicore systems continue to grow. Larger and still fast mainmemory is needed for meeting the demand and avoiding an increase inbacking store accesses that are much slower and less energy efficientthan main memory accesses. LÄS MER
Sammanfattning : Background: The major challenge in memory clinics is to predict development as well as non-development of dementia among the heterogeneous group of patients with cognitive complaints. Since the advent of pharmacological treatment possibilities for patients with Alzheimer s disease (AD), much research has been focused on predictors for dementia since initiation of treatment in the preclinical phase may prevent development of dementia.

Sammanfattning : Parkinson’s disease (PD) is next to Alzheimer’s disease (AD) the second most common neurodegenerative disease. PD has traditionally been characterised as a motor disorder, but more recent research has revealed that cognitive impairments are frequent. LÄS MER
