1. Body Size Evolution in Butterflies
Sammanfattning : Life history research deals with the scheme of resource partitioning to a wide spectra of processes and the trade-offs shaping these events. One of the most fundamental life history trade-offs is the one of at which age- and size an organism should start to reproduce; reaching a large size at maturity is often advantageous in terms of high adult survival and reproductive potential, while to attain a larger size the organisms must prolong juvenile development which is assumed costly in terms of mortality.

2. Nanomechanics – Quantum Size Effects, Contacts, and Triboelectricity
Sammanfattning : Nanomechanics is different from the mechanics that we experience in everyday life. At the nano-scale, typically defined as 1 to 100 nanometers, some phenomena are of crucial importance, while the same phenomena can be completely neglected on a larger scale. LÄS MER
3. Synchronous Reluctance Machine (SynRM) in Variable Speed Drives (VSD) Applications
Sammanfattning : This thesis is comprehensively dedicated to the theoretical and experimental reevaluation of the Synchronous Reluctance Machine (SynRM). A simple approach to derive the SynRM main characteristics and behavior is followed. An introduction to an evaluation of the different control strategies in is given. LÄS MER
4. Time- and size-efficient supercompilation
Sammanfattning : Intermediate structures such as lists and higher-order functions are very common in most styles of functional programming. While allowing the programmer to write clear and concise programs, the creation and destruction of these structures impose a run time overhead which is not negligible. LÄS MER
5. The mechanics in two nanosized systems : Size effect and threshold field
Sammanfattning : This thesis investigates the mechanics in two nanosized system. Paper I investigates a size effect in a cantilever nanowire affecting its resonance frequency. Paper II reveals a threshold field for the formation of a mound by the diffusion of surface atoms on a substrate under a STM-tip. LÄS MER
