1. Thermal Issues in Testing of Advanced Systems on Chip
Sammanfattning : Many cutting-edge computer and electronic products are powered by advanced Systems-on-Chip (SoC). Advanced SoCs encompass superb performance together with large number of functions. This is achieved by efficient integration of huge number of transistors. LÄS MER
2. Summer Climate Variability during the Past 1200 Years in Central Scandinavia – A Tree-Ring Perspective
Sammanfattning : To set the current 20th century warming in a long-term context, significant efforts have been made to reconstruct hemispheric-to-global temperatures beyond the instrumental period. Tree-rings, which have annual resolution and can be precisely dated, have been widely used to infer past climate variability. LÄS MER
3. Effects of warming and nutrient enrichment on feeding behavior, population stability and persistence of consumers and their resources
Sammanfattning : Consumer-resource interactions are the basic building blocks of every food web. In spite of being a central research theme of longstanding interest in ecology, the mechanisms governing the stability and persistence of consumer-resource interactions are still not entirely understood.

4. Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics
Sammanfattning : Multi-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium as the tracer species, in sooting environments such as in diesel engines.

5. Absorption of Sound : On the effects of field interaction on absorber performance
Sammanfattning : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. LÄS MER
