The scale of permanent magnet materials for automotive traction motors

A mathematical model is developed with the purpose of estimating the scale of permanent magnet materials consumption in hybrid and electric automotive traction systems. These estimations are compared to consumption figures from industries such as wind power, HVAC, consumer electronics and industrial machinery. The estimations generated are useful in strategic decision-making for production planning

Från gastkramning till gatuvåld. En etnologisk studie av svenska rädslor

This book is the product of a research concerning fears. Its major object is to demonstrate how fears are structured by different cultural enviroments, and to show how such are formulated and expressed. The important perspective lies in the documentation, analysis and comparison of modern folklore with that of pre-industrial society. Being anchored in the collective fears of these two forms of soc

Development of successful food packaging and logistics in Sweden since 1945

After World War II the food sector in Sweden developed very quickly, following the example of the USA. The introduction of frozen food and self-service stores were rated as the major innovations since 1945, followed more recently by chilled products. For these products both packaging and an efficient supply chain are prerequisites. The innovations were supported by changes in society and by govern

Activation of CO2 by Palladium Complexes Bearing Tridentate PCP Ligands

Popular Abstract in Swedish Avhandlingen berör aktivering av koldioxid genom inskjutningsreaktioner i palladium-kol bindningar. Detta har gjorts med komplexen (PCP)PdMe och (PCP)PdCH2CHCH2. Dessa komplex har också använts i katalytisk karboxylering of ZnMe2och tributylallyltenn. Pga. transeffekten är bindningen mellan palladium och metylgruppen kraftigt försvagad vilket visar sig i det långa bindnThe present thesis deals with the activation of CO2 by insertion reactions into palladium-carbon bonds. This has been realised for the complexes {2,6-bis[(di-t-butylphosphino)methyl]benzene}palladium(II)methyl [(PCP)PdMe] and (PCP)PdCH2CHCH2. These complexes have also been used in the catalytic carboxylation of ZnMe2 and Bu3SnCH2CHCH2. Because of trans influence the palladium-methyl bond is severe

REX - A Computer Programme for PIXE Analysis

The implementation of a physics-based model for non-linear least-squares analysis of proton-induced X-ray emission spectra via a Fortran programme REX is discussed. The modelling of distinct spectral components and of the physical effects involved is briefly discussed. Results are presented in graphical and tabular form. The limitations of the present model are discussed and future refinements ind

A low-power 8-bit folding A/D converter with improved accuracy

In this paper, an accuracy improving method for calibration of mismatch-induced errors in folding A/D converter is presented. With dynamic auto-zero calibration for the folder, the transistor size of folding differential input pairs can be reduced considerably while keeping integral nonlinearity (INL) low. Using this technique, an 8-bit folding A/D converter is designed and simulated in MATLAB. Be
