Även om Sveriges krigsinsatser i till exempel Libyen har som mål att göra världen bättre så är det högst troligt att effekten blir den motsatta.

In schools the temperature of the indoor air is one of the most important factors in terms of the indoor climate. The resulting indoor air temperature is depending on many factors; the temperature of the supply air being one of the more significant one. One fan-assisted natural ventilation system includes a supply air system where the outdoor air should be passively heated respectively cooled when

Gestures, i.e. the symbolic movements that speakers perform while they speak, form a closely interconnected system with speech, where gestures serve both addressee-directed (‘communicative’) and speaker-directed (‘internal’) functions. This article aims (1) to show that a combined analysis of gesture and speech offers new ways to address theoretical issues in second language acquisition (SLA) and

Social movements are series of sustained interactions and collective actions, contentious performances, displays and campaigns by ordinary people outside established political institutions. Yet, why do certain movements persist over a significant period of time while some do not? How do those that persist, sustain themselves and overcome constraints over time, especially those imposed by non-liber

This paper investigates expanding properties of ensembles of random bipartite graphs whose adjacency matrices are Gallager's low-density parity-check matrices. Two methods for calculating the expansion coefficient are demonstrated. It is shown that in the ensemble of the considered bipartite graphs, there exist graphs which have better expanding properties than the previously known expanders.

In this work we study the problem of constructing precoders for spatially multiplexed multiple-input multiple output (MIMO) channels with close to optimal minimum Euclidean distance. In order to exploit the full potential of such designs, an ML detector must be used. Our design takes the decoding complexity into account and constrain it to a reasonable level. For our simplest case, the ML detector

Det har i olika sammanhang uttryckts att förändringarna med Bolognaprocessen skapar en chans att reformera utbildningen i Sverige på ett djupgående sätt och att det gäller att ta vara på möjligheten. Nuvarande förslag leder inte ens i bästa fall till någon genomgripande reform. Förändringarna, om de nu genomförs, får snarare betraktas som en anpassning än en grundläggande reform. Det är kanske klo

As Blum-Kulka, House & Kasper 1989:1 point out, speech acts are “one of the most compelling notions in the study of language use”. The Cross-Cultural Speech Act Realisation Project (CCSARP; Blum-Kulka & Olshtain 1984) analyses two speech acts: requests and apologies across a range of languages and cultures to investigate whether there are universal pragmatic principles in speech act realis

Popular Abstract in Swedish Akrylfibrer, SAN-plast (Styren-AkrylNitril) och ABS-plast (Akrylnitril-Butadien-Styren) är tre viktiga polymerer som tex används för textilier (akrylfibrer) och optiska instrument (SAN). ABS-plast har hög motståndskraft mot kemikalier samt är slagtålig och används tex i bilar. Gemensamt för dessa tre polymerer är att akrylnitril används som monomer. Akrylnitril tillverkPropane ammoxidation catalysts of differing Sb/V ratio and consisting of differing amounts of the V2O5, alpha-Sb2O4, and Sb0.92V0.92O4 phases were prepared. In the first paper, the structure of Sb0.92V0.92O4 was determined by thermogravimetry, X-ray microanalysis, X-ray powder diffraction, and neutron powder diffraction. Sb0.92V0.92O4 was found to have a defective rutile structure involving catio
