A Modified Point Coordination Function (Modified PCF) in IEEE 802.11 Wireless LAN

With recent advances in wireless technologies, wireless LANs are becoming increasingly widespread as an alternative to fixed access technologies. The IEEE 802.11 standard has gained the most popularity among the different standards and is currently being deployed both within enterprises as well as being used for public access. One of the weaknesses of the basic medium access in the 802.11 standard

The marked status of Accent 2 in Central Swedish

Based on results from psycholinguistic and neuro- linguistic research on the perception of word ac- cents in Central Swedish, we argue that Accent 2 could be seen as “marked,” as opposed to the un- marked Accent 1. The markedness of Accent 2 is assumed to be both phonetic, due to its relatively more complex high tone, and cognitive, due to the fact that the Accent 2 tone activates more word forms

The Forensic Architecture Project : Virtual imagery as evidence in the contemporary context of the war on terror

‘Virtual imagery as evidence in the contemporary context of the war on terror’ This paper explores the evidentiary role of virtual reproductions produced by the research project Forensic Architecture in the context of the contemporary battlefields of the war on terror. The digitization of war has created a networked landscape whose processes often remain invisible to the public. Although drone op

Local characterisation of fluid flow in sandstone with localised deformation features through fast neutron imaging

Understanding fluid flow through rocks is of key interest in hydrocarbon production and CO(2) sequestration, amongst other applications. Such fluid injection or extraction from subsurface reservoirs can be significantly modified (increased or decreased) by deformation and in particular by localised deformation features (fractures, shear bands and compaction bands). How such deformation alters flui

Experimental Validation of the Brush Tire Model

The paper presents an experimental validation of the physically based brush-tire model towards the tire behavior in a number of different realistic conditions. Results are presented of measurements performed with summer, winter and studded tires on different road foundations such as wet and dry asphalt, basalt, snow and ice. The purpose behind the validation is to study the possibilities to use th

Metabolic impact of certain dietary proteins and/or amino acids - Glycaemic and hormonal responses to carbohydrate meals in healthy subject

Popular Abstract in Swedish Förekomst av fetma och typ 2 diabetes ökar i Sverige, liksom globalt. Över 360 miljoner människor har diabetes och prognosen för år 2030 är drygt 550 miljoner (IDF 2011). Att arbeta med förebyggande åtgärder för att minska denna utveckling är därför nödvändigt. Något som har stor betydelse för hälsan är vilken typ av mat vi väljer att äta och dess näringsmässiga kvaliteRe-occurring hyperglycaemic episodes promote subclinical low-grade inflammation and CVD in type 2 diabetes, emphasising the therapeutic role of tight blood glucose regulation. A tight blood glucose regulation is probably beneficial also in healthy subjects and mild elevations in postprandial glycaemia and triglycerides are associated with impaired flow-mediated dilation and increased markers of ox

Analytical Supercritical Fluid Extraction of Lipid Containing Samples

Traditionally, sample work-up has been associated with different kinds of liquid extraction techniques involving a large consumption of hazardous solvents. There are today regulations that aims at replacement of dangerous chemicals which has created a need for new extraction techniques. During the last decade supercritical fluid extraction (SFE) has become a good alternative for sample pretreatme
