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
