1. Experimental Evolution : and Fitness Effects of Mutations
Sammanfattning : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. LÄS MER
2. Evolution of artificial defects during shape rolling
Sammanfattning : Very often defects are present in rolled products. For wire rods, defects are very deleterious since the wire rods are generally used directly in various applications. For this reason, the market nowadays requires wire rods to be completely defect-free. Any wire with defects must be rejected as scrap which is very costly for the production mill. LÄS MER
3. Evolution and the Backward Induction Problem in the Repeated Prisoners’ Dilemma
Sammanfattning : The finitely Repeated Prisoners’ Dilemma (RPD) is a model of a social dilemma where cooperation is particularly hard to come by. The standard way to solve the game is usingbackward induction, which by a particular logic gradually eliminates all cooperation from the end of a repeated game. LÄS MER
4. Curbing Dependencies in Software Evolution of Object-Oriented Systems
Sammanfattning : Relationships between classes and objects in object-oriented software are necessary in order for the parts of the systems to provide dynamic behavior. These inherent relationships also create dependencies which can give rise to problems for software evolution of object-oriented software systems. LÄS MER
5. Modeling defect structure evolution in spent nuclear fuel container materials
Sammanfattning : Materials intended for disposal of spent nuclear fuel require a particular combination of physical and chemical properties. The driving forces and mechanisms underlying the material’s behavior must be scientifically understood in order to enable modeling at the relevant time- and length-scales. LÄS MER
