Handheld computing and mobile information systems are continuously breaking new ground, with an increased importance for business. However, there is evidence that we still have lessons to learn concerning the design of handheld information systems. Handheld information system poses challenges to the designer in the unique properties of handheld technologies and the conditions of use of handheld te
For ergonomics/human factors solutions to be beneficial for society and its members it is vital to apply a systems level perspective. Students who will be the future engineers, designers, and managers of socio-technical systems need to gain an understanding of how ergonomics/human factors can be integrated in the design of workplaces, organisations, products, and services. This paper gives example
New trends in rituals and customs concerning death and funerals.

Popular Abstract in English Animal flight has always intrigued people, and different aspects of animal flight have therefore widely been studied by biologists, physicists and engineers. At least to me, the aspect concerning the aerodynamics of animal flight in particular is very interesting because of the complex temporal varying wake dynamics as a result of continually wing morphing in flapping fThe efficiency and performance of a flying animal is directly related to the aerodynamics around its body and flapping wings. Here, I have developed methods for quantifying the wake dynamics around a flying animal. The results are used to estimate the aerodynamic performance of flapping flight. Using these methods, I have studied flight of the Pied Flycatcher (Ficedula hypoleuca), the Pallas’ Long
Neutral photodissociation processes and non Franck-Condon effects in the N2 and O2 molecules induced by excitation with synchrotron radiation photons have been studied in the 15-35 eV region. Neutral dissociation processes have been studied by monitoring dispersed fluorescence from excited N and O atoms. The excited atoms are created through excitations to members of the molecular Rydberg seri
The philosophical debate about liberty has recently gained in complexity and political relevance through the revival of the republican understanding of liberty as the absence of asymmetric power relations or domination. As a staunch defender of the importance of theorizing liberty in this way, I nevertheless argue that a theory of liberty in the social world needs to be conceptually multifaceted a
The book is a history of the medieval city of Söderköping in the Swedish province of Östergötland, which was founded in the beginning of the thirteenth century. It is based on the numerous archaeological finds that have been unearthed in the city, as well as on the documentary sources in various archives.
A low-rate turbo coding scheme based on superorthogonal convolutional encoders is examined. We analyze the asymptotic performance that can be achieved when both the code length and the number of iterations tend to infinity and present a bound on the iterative limit of this superorthogonal turbo code construction. Simulations of the codes with large permutors (interleavers) confirm the results of t
Popular Abstract in Swedish Denna avhandling behandlar studier av elektriska komponenter med egenskaper dominerade av s.k. kvantfenomen. Dessa komponenter har ur flera synvinklar många önskvärda egenskaper, t.ex. är vissa av dem extremt snabba, andra har mycket låg effektförbrukning eller hög packningstäthet. Avhandlingen är indelad i två delar. Först en introduktion till ämnet där bakomliggande tThis thesis deals with electrical measurements on quantum devices. The thesis is divided into three major areas: electrical characterization, semiconductor devices, and metal devices. The electrical characterization part present problems and advantages with the measurement techniques used in the the thesis, .i.e., Current-Voltage; Conductance, including higher order harmonics; Capacitance; Cross-
Several serious problems such as material durability and fouling in the High Temperature Heat Exchanger (HTEH) for Externally Fired Micro Gas Turbines (EFMGT) cause the low thermal efficiency. In this study for increasing the thermal efficiency, a duct around a cylindrical fixed bed combustor which burns wood pellets is proposed and two different designs, empty and porous material filled, are inve
The term discriminate, in itself, simply means to make distinctions or discern differences. In that sense, to discriminate is to discern the difference between red and green when picking a red apple out of a fruit basket or to discern differences in physical appearance when noticing a friend in a crowd. Morally and legally, however, discrimination is used to denote a differentiation that is unfair
