16. Population and Community Dynamics in Variable Environments
Sammanfattning : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. LÄS MER
17. Fundamentals of High Power Impulse Magnetron Sputtering
Sammanfattning : In plasma assisted thin film growth, control over the energy and direction of the incoming species is desired. If the growth species are ionized this can be achieved by the use of a substrate bias or a magnetic field. Ions may be accelerated by an applied potential, whereas neutral particles may not. LÄS MER
18. Integrated Transmitters for Cellular User Equipment–Wideband CMOS Power Amplifiers and Antenna Impedance Tuners
Sammanfattning : The digital cellular systems era started about thirty years ago with the release of the first digital cellphones. These first digital cellphones were very different from today’s slim and esthetic cellular pocket computers. They were not mass-produced in million units a day, and they were designed for radio performance rather than appearance. LÄS MER
19. On Power Control and Scheduling to Mitigate Adjacent Channel Interference in Vehicle-to-Vehicle Communication
Sammanfattning : Safety applications play an essential role in supporting trac safety and eciency in next generation vehicular networks. The eciency of safety applications depends heavily on the establishment of reliable communication since these types of applications have strict requirements on latency and reliability. LÄS MER
20. On Signal Dependent Basis Functions, Estimation of Event Related Potentials and Multiple Window Spectrum Analysis
Sammanfattning : The three parts of this thesis are different examples of utilization of signal dependent basis functions in the estimation procedure. The first part surveys a number of parametric methods applied to estimation of single ERP (P300). LÄS MER
