A model of scattering of three one-dimensional particles is constructed by means of the extension theory of selfadjoint operators. The dispersion equation for the three-particle bound state energy is obtained and an exact mathematical expression for the corresponding wave functions is derived

The study examines from a cultural analysis perspective how habilitation training can learn adolescents who use wheelchair to become more integrated in urban environments. The wheelchair is considered in this study mainly as an emancipator. A specific habilitation training, called “Wheelchair in the city”, is studied, that teaches adolescents to overcome the obstacles they meet in urban environmen

Given the uncertainty and complexity of security risk analyses, there is a great need of tools for contextual inquiry supporting assessment of risk with multi-value scales according to different stakeholders’ point of view. Such tools can be used at individual level to help develop the understanding of a problem space. At the collective level, they can be used as a mean of communication to support

The main aim of this thesis is to defend moral realism. In chapter 1, I argue that moral realism is best understood as the view that (1) moral sentences have truth-value (cognitivism), (2) there are moral properties that make some moral sentences true (success-theory), and (3) moral properties are not reducible to non-moral properties (non-reductionism). Realism is contrasted with non-cognitivism,

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

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
