The aim of this study was to evaluate the effects on the working postures and movements of a cashier when two different locations of the scales (one to the left of the cashier, the other under the conveyer belt in front of the cashier) were used in a grocery checkout system. Two cashiers (of average stature and short stature) were videotaped while working, in both sitting and standing working posi

What is normally described as bias? A possible definition comprises attempts to distort or mislead to achieve a certain perspective, i.e. subjective descriptions intended to mislead. If designers were able to exclude bias from informing systems, then this would maximize their effectiveness. This implicit conjecture appears to underpin much of the research in our field. However, in our efforts to s

Popular Abstract in Swedish Hur lever man ett avskilt liv i dagens moderna värld? Kan man bevara en distinkt religiös och kulturell identitet i en omgivning som propagerar för pluralism och öppenhet? Integritet och avskildhet från det omgivande samhället är viktiga inslag i charedims (ultraortodoxa judars) kulturella identitet. Att argumentera för dessa värden är lätt, att praktiskt konkretisera The dissertation focuses on the Haredi (ultra-orthodox Jewish) journal The Jewish Observer, published since 1963 by Agudath Israel of America, suggesting that the publisher uses the journal as an instrument to help the readers to maintain a distinct Haredi identity in urban, non-Haredi environments and not only in their own, isolated milieu. The articles of the journal are understood as resources,

Numerical experiments, constituting of 90 simulations in FDS, were used in this paper for two purposes. Firstly an evaluation of previously derived correlations for ceiling jet excess temperatures and velocities was performed. Secondly the numerical experiments were used to demonstrate how computer simulations could be used as a complement to actual fire experiments in fire science research. The

The paper is exploring a role of memory in the formation of cultural identity in the circumstances of migration. In particular, the attention is directed towards ritual practices and the role of such collective actions for reinforcing the ontological questions about selfhood, belonging to a group and identity of the immigrants. It will be put forward that the proper conduct of funerary practices s

Popular Abstract in Swedish Inom vetenskapen finns det många exempel på nätverk av ett stort antal samverkande delar. Det kan vara aktiviteten i en levande cell, myror i en myrstack eller djur i ett ekosystem. Slumpmässiga booleska nätverk, som är ämnet för denna avhandling, är ytterligare ett exempel. Dessa nätverk är matematiska konstruktioner som är förhållandevis lätta att undersöka med hjälp There are many examples of complex networks in science. It can be genetic regulation in living cells, computers on the Internet, or social and economic networks. In this context, Boolean networks provide simplistic models that are relatively easy to handle using computer simulations and mathematical methods. A good understanding of Boolean networks may form a foundation to investigations of more c

If engineering designers consciously design product and package in an integrated manner, there is a great potential for industrial global enterprises to develop and produce mechanical products, such as exhaust extraction systems, ear washer machines and fuel handling systems while simultaneously obtaining error-free deliveries, saving costs and avoiding quality problems. Thus, the authors of this

This paper investigates both positional dependence in systems with friction and the influence an increase in temperature has on the friction behavior. The positional dependence is modeled with a Radial Basis Function network and the temperature dependence is modeled as a first order system with the power loss due to friction as input, eliminating the need for temperature sensing. The proposed meth

This work concerns an experimental study of pressure drop and heat transfer for turbulent flow inside a U-duct with relevance for tip cooling of gas turbine blades. The U-duct models the internal blade cooling flow passages. Both friction factors and convective heat transfer coefficients were measured along the bend (turn) part of the U-duct for three different rib configuration cases, namely (a)

Popular Abstract in Swedish Vi lever i ett samhälle under ständig utveckling där användandet av nya kemikalier ökar explosionsartat. Med vardagligt användande av avancerade material såsom extremt tunna skärmar, billiga och miljövänliga bekämpningsmedel och läkemedel – vilka ofta är inspirerade av naturens komplexitet – kommer ett behov av organisk syntes. För att tillverka den här typen av komplicThis thesis deals with the development of novel methodologies for the synthesis of hetero- and carbocycles enabled by transition metal catalysis. The second chapter of the thesis describes a gold-catalyzed three-component reaction to form a variety of substituted oxazoles from readily available N-benzylimines, terminal alkynes, and acyl chlorides. Sacrificial benzyl groups are used to merge two o
