1. Insights into Stability Aspects of Novel Negative Electrodes for Li-ion Batteries
Sammanfattning : Demands for high energy-density batteries have sharpened with the increased use of portable electronic devices, as has the focus global warming is now placing on the need for electric and electric-hybrid vehicles. Li-ion battery technology is superior to other rechargeable battery technologies in both energy- and power-density. LÄS MER
2. Lake sediment as environmental archive : natural and anthropogenic influence on the chronology of trace elements
Sammanfattning : The focus of this thesis is the historical pollution of some seldom-monitored trace elements (SMTEs; Ag, Be, Ga, In, Sb and Tl) that have been involuntarily released for several thousands of years but whose usage have increased during the industrial era. Sediment cores from four rural lakes in a south to north transect in central Sweden, and two urban lakes have been used as environmental archives for chronological studies. LÄS MER

4. Selected topics in frequency estimation
Sammanfattning : Frequency estimation has been studied for a number of years.One reason for this is that the problem is easy to understand,but difficult to solve. Another reason, for sure, is the largenumber of applications that involves frequency estimation, e. LÄS MER
5. Spatial and spatio-temporal processing with antenna arrays in wireless systems
Sammanfattning : This thesis treats some modeling and estimation problems inthe fieldof antenna array signal processing. With multipleantennas at thereceive side, the spatial dimension is added,and processing is performed in both the temporal and spatialdomain. LÄS MER
