Fuel economy and emissions are the two central parameters in heavy duty engines. High exhaust gas recirculation rates combined with turbocharging has been identified as a promising way to increase the maximum load and efficiency of heavy duty spark ignition engines. With stoichiometric conditions, a three way catalyst can be used, which keeps the regulated emissions at very low levels. The Lambda

The paper develops an analytical framework for understanding the role of social media in the 2011 North African uprisings. It argues that analysis of the role of Facebook, Twitter, and other social media tools should be broken down into two distinct phases: a pre-mobilisation phase and a collective action phase. Using frame analysis and the notion of connective action, the paper demonstrates that

Denna studie syftade till att få en djupare förståelse kring hur gömda kvinnors livssituation ser ut och vilken roll som det svenska samhällets skydd och stöd har i kvinnornas livssituation och vardag, samt vilka eventuella konsekvenser kvinnorna får i sin vardag med bakgrunden av det stöd och skydd som samhället erbjuder. De material som använts inom studien bygger huvudsakligen på den skuggrap

The notion of design research entails research where design practice forms part of the knowledge production. Based on our characterization of the nature of design, we propose to conceptualize this kind of research as programmatic design research. Two ongoing PhD projects in interaction design are presented as examples of programmatic research processes, highlighting issues to do with the virtues a

The article presents and discusses a number of recent scholarly attempts to investigate theological and/or religious dimensions of music. On the basis of critical interpretations of these (Anglophone and German) contributions the article proposes an interdisciplinary approach to a theological aesthetics of music. Such a methodology necessitates any "theologizing" to respect the singular qualities

In children’s literature nonhuman primates are often represented either as ferocious beasts or as curios and charmful vicarious children. In this article I demonstrate how these different constructions interestingly coexist in the popular story ‘‘The monkey that would not kill’’, written by the Scottish evangelist and professor of the natural sciences Henry Drummond in 1891. My study anchors the f

In many applications, especially in the process industry, low-level controllers are the workhorses of the automated production lines. The aim of this study has been to provide simple tuning procedures, either optimization-based methods or tuning rules, for design of low-order controllers. The first part of this thesis deals with PID tuning. Design methods or both SISO and MIMO PID controllers bas

Den offentliga statistiken inom äldreomsorgsområdet är för närvarande begränsad till mängdstatistik (Statistik - socialtjänst 2000:5, Socialstyrelsen 2000 och Hälso- och sjukvårdsstatistisk årsbok 1999, Socialstyrelsen 2000). Från denna statistik erhålles uppgifter om antalet äldre som får vård och hjälp fördelade på ålder, kön och vårdinsats samt vårdkostnader. För att få insikt i äldreomsorgssys

It has been suggested that a parent–teacher–student conference should centre on the capacities and good qualities of the student. This article focuses on teacher discourse in situations where the students’ answers (in mathematics tests, written assignments etc.) are either entirely or almost entirely correct. The study shows that, in eight cases out of ten, the comments made reflect a “deficiency
