Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. Since the positions of the rollers, and thereby also the load distribution, depend on the two connecting spans, it has been necessary to inclu

A systematic study of cell membrane morphologies whose structure is governed by cubic symmetries has been performed. It is suggested that they are described by periodic cubic surfaces for which space filling surface foliations given by truncated Fourier series defined by the space groups is used as structural representations. Using this a method is developed which enables a direct ultrastructural

We consider whether stellar collisions can explain the observed depletion of red giants in the Galactic center. We model the stellar population with two different IMFs: 1) the Miller-Scalo and 2) a much flatter IMF. In the former case, low-mass main-sequence stars dominate the population, and collisions are unable to remove red giants out to 0.4 pc although brighter red giants much closer in may b

A business analyst who commences an investigation into design requirements for a new work system probably does not ‘label’ her inquiry process as research. However, a research perspective is needed if a productive learning spiral is to be established in which ‘useful’ systems can be created. Systematic, collaborative inquiry adopting an complex, open systems perspective is required in order to est

Brief description of the medieval seal of Dalby monastery, on which the emblem for the 950th jubilee of the construction of the church was based.

Law and its countless legal, academic, professional and institutional manifestations, all being intrinsically social, fall within the scope of sociological inquiry. It is, therefore, not surprising if some sociologists and jurists have tried to bring the benefits of sociological ideas to legal thought and practice. Introducing sociological insights into law, a feasible and useful project in theory

The purpose of this study is to elucidate affordances and meaning-making processes where students in Compulsory lower secondary education learn to play music together in music class. The data consists of a series of observed music lessons, performances and stimulated recall interviews in two 8th form classes, video recorded in the course of one term. The analysis focuses on students’ and their tea

The main issues discussed in this dissertation are the questions how and why farming and animal husbandry were introduced in southern Scandinavia. The Löddesborg site by the Öresund coast supplied most of the basic materials used in the analysis. Simliar sites in Scania and Blekinge, as well as finds of Limhamn-axes, pointes butted axes, polygonal axes, and dolmens complete the picture of the neol

A particle filter based solution to the out-of-sequence measurement (OOSM) problem is proposed. The solution is storage efficient, while being computationally fast. The filter approaches the multi-OOSM problem by not only updating the estimate at the most recent time, but also for all times between the OOSM time and the most recent time. This is done by exploiting the complete in-sequence informat

The aim of this chapter is to contribute to the debate by arguing for an approach to validity in which (1) the domain of discovery and the domain of justification are brought together and are seen as being intertwined in a transactional sense, (2) the justification process is seen to be endowed with an experimential and a contextual dimension, and (3) a pro¬ces¬sual, historical pespective is thus
