Where, if, and how, should researchers draw the limit between gesture proper and semiotically less complex forms of bodily conduct that do not quite qualify as gesture? This is the question of a lower limit of gesture (Andrén 2010). In accord with a comparative semiotic approach (Kendon 2008) I suggest that the question is best understood, not as a binary distinction between gesture and non-gestur

Robust stability of linear systems in presence of bounded uncertain time-varying time delays is studied. The time delay robustness problem is treated in the Integral Quadratic Constraint framework. The stability criterion is formulated as a frequency dependent linear matrix inequality, or equivalently as a Semi-Definite Program (SPD). Therefore, the criterion can be checked efficiently by using va

Popular Abstract in Swedish Astma och hösnuva (allergisk rinit) är två närbesläktade sjukdomar som båda har sin grund i en långdragen, kronisk inflammation i luftvägsslemhinnan. Vid både astma och hösnuva har slemhinnan en benägenhet att reagera kraftigare än normalt på retningar (s.k. hyperreaktivitet). Inflammationen och hyperreaktiviteten regleras av hundratals olika signalsubstanser (mediatoreMucosal inflammation and airway hyperreactivity are regulated by hundreds of different mediators. The recent discovery of gaseous mediators, produced and active within the airways, opens new possibilities for identification of therapeutic targets and ways to monitor airway inflammation. This thesis is focused on two such mediators, nitric oxide (NO) and carbon monoxide (CO) along with their role i

Many product development projects nowadays use computer-aided engineering systems in the analysis of product proposals. It is therefore important to appropriately integrate the analyses activities in the product development process. One important aspect of this integration is how to handle the initiation of the task: identifying the need, planning the task and its monitoring, and communicating it

Design patterns are abstract descriptions of solutions to often recurring problems. They are a means to communicate experience in design. Over the past years, along with the increase in popularity of object-oriented design patterns, some problems with the use of them have been identified. One of these lies in documenting software systems using design patterns. Experience has shown that both in the

The most common PID design methods in industry are based on formulas. This article will present some major advantages of instead using the power of computer based softwares for PID controller design. The Matlab based software used in this work was developed in 2007 and derives robust, IAE minimizing, PID controllers. The experiences of using this software are collected in this article and include

Decision-making in requirements engineering often needs to be done in the presence of uncertainty. Rigorous methods can help to increase the probability of making the most appropriate decisions under the given circumstances. Robustness is a measure for the degree of stability of a solution in case of changes in the problem parameters. This paper presents a method (called DECIDERelease) that applie

Genetic and morphometric variation was studies in the three closely-related taxa Silene vulgaris (a widespread weed), S. uniflora ssp. uniflora (restricted to coastal habitats) and S. uniflora ssp. petraea (endemic to Sweden and confined to open limestone habitats). The majority of alleles at the investigated allozyme loci are common to the three taxa, but the taxa show significant differences in

Abstract in UndeterminedIn this article we examine the emergence of social worker training in the Nordic countries and discuss the possible effects that the social democratic welfare regime has had on such training. We also discuss the development in recent decades of the academisation of the training and the establishment of social work as a subject of research and teaching. The early history of
