1. Bounds on the Performance of PSK Block Codes
Sammanfattning : In wireless communication, the minimum Euclidean distance between codewords is a major factor for the ability to correct errors in messages, and it is of interest to maximize the minimum Euclidean distance. The thesis improves previously established general upper bounds on minimum Euclidean distance of phase shift keying block codes. LÄS MER
2. Combinatorial Optimization : Three Applications
Sammanfattning : Combinatorial optimization is a diverse area of mathematics. It concerns optimization on feasible regions defined by discrete sets, graphs, hypergraphs, matroids, etc. . . LÄS MER
3. Nanolatexes: a versatile toolbox for cellulose modification
Sammanfattning : Cellulosic materials are widely used in our everyday lives, ranging from paperand packaging to biomedical applications. However, in most applications, cellulose must coexist with hydrophobic polymers which can be challenging due to its hydrophilic character. This has encouraged the exploration of chemical and physical modifications of cellulose. LÄS MER
4. Gene-environment interactions between HPA axis regulatory genes and stressful life events in suicide attempts
Sammanfattning : Suicide is a leading cause of death. In the future, treatment for suicidal behavior, as well as public health prevention and/or intervention efforts, may be guided by genetic epidemiology. This research is informed by biological alterations which have been previously observed in suicidal behavior. LÄS MER
