When the ethnographer Wilson Wallis did his first fieldwork among the Canadian Mi’kmaq Indians 1911, one recurrent character in their oral tradition was the traditional culture hero Kluskap. When Wallis returned to Nova Scotia in 1953 he found that not many Mi’kmaq in the thirties had heard about Kluskap, and if they had, it was through books or the television series “The Adventures of Glooscap”.

Numerical analysis, such as the finite element method is the most used computational procedure for nonlinear deformation and strength analysis of structures. In order to obtain meaningful results the material behaviour must be described and simulated accurately. Another important element in order to perform the simulation is a robust and accurate numerical integration algorithm. The present paper

This dissertation investigates nanomagnetism in small transition metal clusters and the diluted magnetic semiconductor (Ga,Mn)As. We derive quantum mechanical models aimed at a realistic description of the low energy physics in these systems. The main focus of the work presented is on magnetic anisotropy, the effects of spin-orbit interaction and quantum geometric phases. The first part of the the

We consider the problem of modeling and control of the nonlinear dynamics of a micro manipulator, utilized for machining operations in combination with industrial robots. Position control of the micro manipulator is a challenging problem because of the actuation principle, which is based on piezo-actuators with inherent nonlinear behavior. The major nonlinearities in the manipulator are identified

In this introductory chapter the authors summarize the chapters in the book by identifying and describing a number of dimensions on which the various chapters, and descriptions of decision making processes more generally, can be located. These dimensions include: individual or institutional perspective, theoretical tradition, theoretical or empirical focus and types of creative aspects of the deci

Kapitlet diskuterar den grundläggande frågan i det moderna samhället som den om hur man kan och bör leva i en värld där inget är nödvändigt och allt ter sig möjligt. Detta existentiella, sociala och politiska problem blev också en gång sociologins fundamentala frågeställning. Följaktligen har disciplinen utvecklats som en ständigt varierad diskussion om förhållandet mellan kontingens och livsförin
