A new versatile computer controlled electrochemlcal/ESR data acquisition system has been developed for the Investigation of short-lived radicals with life-times of 20 milliseconds and greater, Different computer programs have been developed to monitor the decay of radicals; over hours or minutes, seconds or milliseconds. Signal averaging and Fourier smoothing is employed in order to improve the signal to noise ratio. Two microcomputers are used to control the system, one home-made computer containing the M6800 chip which controls the magnetic field, and an IBM PC XT which controls the electrochemistry and the data acquisition. The computer programs are written in Fortran and C, and call machine language subroutines, The system functions by having the radical generated by an electrochemical pulse: after or during the pulse the ESR data are collected. Decaying radicals which have half-lives of seconds or greater have their spectra collected in the magnetic field domain, which can be swept as fast as 200 Gauss per second. The decay of the radicals in the millisecond region is monitored by time-resolved ESR: a technique in which data is collected in both the time domain and in the magnetic field domain. Previously, time-resolved ESR has been used (without field modulation) to investigate ultra-short-lived species with life-times in the region of only a few microseconds. The application of the data acquisition system to chemical systems is illustrated. This is the first time a computer controlled system whereby the radical is generated by electrochemical means and subsequently the ESR data collected, has been developed.

Cette thèse présente une approche complète de comparaison de visages 3D qui exploite l'information de volume et sa robustesse afin de réduire l'influence néfaste de l'angle de prise de vue et de l'illumination. Deux contributions majeures charpentent ce travail: l'acquisition et la comparaison de surfaces faciales. L'acquisition par projection de lumière structurée convient à la capture de surfaces faciales. La précision en profondeur de l'ordre de 1 mm satisfait au besoin en reconnaissance. La rapidité d'acquisition et la coopération naturelle du sujet remplissent les conditions élémentaires d'une utilisation pratique. La reconnaissance des surfaces faciales a été réalisée par comparaison géométrique de profils extraits par plans parallèles. La symétrie intrinsèque des visages a permis d'optimiser la mise en correspondance des profils. L'information géométrique a été combinée avec la comparaison de niveaux de gris mesurés dans les images acquises.

Firms obtain new technology either through internal R&D or through acquisitions. These two approaches are usually labeled as "make" and "buy" strategies. In this paper, I examine the relation between a firm's choice of "make" or "buy" and the performance measures used in the firm's CEO compensation contract. I focus on the two major differences between "make" and "buy" strategies: the risk levels and accounting treatments. I then examine the differential implications of accounting-based and stock-based performance measures on managers' incentive in choosing between the two strategies. Using data from US high tech industries, I find that, firms relying on "buy" approach to obtain technology tend to depend more on the accounting-based performance measures, while those firms who innovate through R&D activities skew toward stock-based pay especially stock options

This thesis by publication presents a study on English adpositions (e.g. to, in, at, from, in frontof, through). It attempts to offer a solution to the following three outstanding problems, whichare presented in each of the three parts making up the thesis, preceded by a general introduction(chapter 1) and followed by the general conclusions (chapter 7). The first part includes chapter2, and discusses the problem of What is the relation between adpositions and the non-linguistic,visual content they represent. The second part includes chapters 3 and 4, and discusses theproblem ofwhat is a proper compositional theory of the Syntax and Semantics of adpositions.The third part includes chapters 5 and 6, and discusses the problem of what is the psychologicalreality of this theory, regarding adults and children’s data.The following three solutions are suggested. First, the relation between adpositions and theircorresponding visual information is an isomorphism: adpositions capture how we “see” possiblespatio-temporal relations between objects, at a flexible level of fine-grainedness. Second, aproper compositional treatment of adpositions treats each syntactic unit (in front, of ) as offeringa distinct semantic contribution, hence spelling out a restricted instance of a spatio-temporalpart-of relation. Third, this compositional treatment of adpositions can also stand as a theory ofon-line interpretation in adults and a theory of their acquisition in children.These three answers are couched within a single theoretical approach, that of Discourse Representation Theory, and offer a unified solution to three apparently distinct problems regardingspatial adpositions and their linguistic properties.

Abstract Background: Between 1991 and 2001 the number of firms acquired by other firms tripled (Johnson & Scholes, 2005). This trend has led to a huge increase in cross-border acquisitions, where Sweden is no exception. Statistics show that companies with U.S. origin are the ones that acquire most Swedish companies (Nutek, 2007). Hence, acquisitions made by U.S. businesses will presumably influence managerial issues in Sweden in different ways. Problem and purpose: An industry that is characterized by many merger and acquisitions is the car industry. Ford Motor Company’s acquisition of Volvo Cars is of particular interest to address. Several conditions within the company changed due to the acquisition process, including the type of management. This might have affected Volvo Car’s relation with its labour union IF Metall to some extent, and thus, creating an interesting area of research. The purpose with this thesis is to investigate how the relation between a labour union and a company is affected when U.S. and Swedish types of management are mixed as a result of an acquisition. Method: In order to fulfill the purpose of this thesis a qualitative case study approach is used. The primary data is collected through interviews with people connected to Volvo Cars and IF Metall. In addition to this the authors incorporated secondary data which is based on literature, articles and academic publications. Conclusions: When a U.S. company acquire a Swedish company the relation between the labour union and the acquired company are affected in several ways. The labour union and the members can expect to have less influence in the decision making process, there will be less resources devoted to work related training programs, the competence level of the members will decrease and the working conditions will become worse.
