- A transition from Microstrip to Ridge Gap Waveguide (RGW) has been studied and numerically analyzed in terms of S parameters. The RGW technology shows potential to be used up to THz frequencies. Therefore, good transitions are needed in order to make possible the measurements of RGW components at frequencies above 100 GHz.

Kartläggning av invandrarföretagande i Norrköping och Linköping
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport har sammanställts mot bakgrund av att Norrköpings och Linköpings kommuner har uttryckt ett behov av en kartläggning av invandrarföretagandet i regionen. Kartläggningen är tänkt att tjäna som underlag för kommunerna i deras arbete för främjande av invandrares företagande i regionen, men även fungera som ett diskussionsmaterial för vidare forskning kring invandrarföretagandets lokala och regionala struktur. Uppdraget för rapporten är att dels kartlägga vilken typ av företag som drivs av invandrare och personer med utländsk bakgrund i kommunerna och dels att beskriva företagarnas bakgrundskarakteristika. Kartläggningen gäller uppgifter från det senaste år för vilket data finns tillgängliga, vilket i skrivande stund innebär år 2004.

- Evolution of Bateson-Dobzhansky-Muller (BDM) incompatibilities is thought to represent a key step in the formation of separate species. They are incompatible alleles that have evolved in separate populations and are exposed in hybrid offspring as hybrid sterility or lethality. In this study, we reveal a previously unconsidered mechanism promoting the formation of BDM incompatibilities, meiotic drive. Theoretical studies have evaluated the role that meiotic drive, the phenomenon whereby selfish elements bias their transmission to progeny at ratios above 50:50, plays in speciation, and have mostly concluded that drive could not result in speciation on its own. Using the model fungus Neurospora, we demonstrate that the large meiotic drive haplotypes, Sk-2 and Sk-3, contain putative sexual incompatibilities. Our experiments revealed that although crosses between Neurospora intermedia and Neurospora metzenbergii produce viable progeny at appreciable rates, when strains of N. intermedia carry Sk-2 or Sk-3 the proportion of viable progeny drops substantially. Additionally, it appears that Sk-2 and Sk-3 have accumulated different incompatibility phenotypes, consistent with their independent evolutionary history. This research illustrates how meiotic drive can contribute to reproductive isolation between populations, and thereby speciation.

- In intense and fast road cycling races, various accidents pose a great threat to cyclist safety. There is a lack of in-depth research on helmet performance and cyclist head injury in road cycling races. In this paper, based on collecting and summarizing the typical accident scenarios of road cycling races, models of road bicycle, anthropologic characteristics of cyclists and helmets are constructed with experimental and computational methods, and the head injury protection performance of helmets and cyclist's head injury response in typical accident scenarios are comprehensively analyzed and evaluated. The results show that the helmet can play a significant injury protection effect, but serious head injury may still occur in some scenarios; different helmets have significant differences in cyclist's head injury protection, and there is no direct correlation with the price. There are significant differences in the effectiveness of helmets for head injury protection among cyclists of different body sizes, with the 50th percentile adult men having the lowest peak kinematic response and injury risk, the 5th percentile adult women having the highest predicted values for all injury criteria, and at least 55% of female cyclists having a significant risk of skull fracture and severe brain injury. None of the accident boundary parameters examined in this study (accident speed, friction coefficient, and slope) had a significant effect on cyclist head injury in the accident scenarios; the Union cycliste Internationale stipulates that helmets may not be worn five kilometers from the end of the climb, while this study recommends cyclists wear safety helmets throughout the road cycling races. This study will provide a reference for the design of safety helmets for road cycling races, as well as data to support the improvement of road cycling race rules.
