Outdoor ranges are commonly used for accurate RCS measurements of full scale vehicles with or without camouflage. Furthermore, ISAR processing is often used to obtain high quality imagery of the objects. However, these images do not show the vehicles in the environment where they are supposed to operate. This paper describes a ground based SAR system that is used to make accurate measurements on v
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
Wave cycle distributions are notoriously difficult to calculate. Available analytic approximations, like those suggested by Longuet-Higgins (1983) and Cavanie, Arhan and Ezraty (1976) make use only of a few spectral moments, and are unreliable for moderate waves. To find distributions under general spectrum shape and parameters one has to use efficient numerical algorithms based on high-dimensiona
A radioactive variant of the cytostatic agent cis-dichlorodiammineplatinum(II), cisplatin, was synthesised from 191PtCl4. The 191Pt-cisplatin was found to be a sterile product of high radionuclide, radiochemical and chemical purity. The pharmacokinetics of platinum in tumour tissue and organs at risk of fourteen patients undergoing treatment with cisplatin were studied by exchanging a small fracti
Evaluating SAR for multi-antennas is difficult and impractical due to the arbitrary power allocation and phase of the electric fields from different antennas causing the total field to change randomly. In this context, a simplified approach was recently proposed for assessing SAR when more than one antenna is transmitting simultaneously. The metric of time averaged simultaneous peak SAR (TASPS) wa

This thesis is a summary of six papers which concern synthesis of optically active bicyclo[2.2.2]octane derivatives. The derivatives prepared are important building blocks in a study towards a possible replacement of the diterpenoidic part of taxol, (baccatin III), so as to construct a taxol mimic. Some of the derivatives have also been developed into new bidentate ligands. TitaniumIV complexes of
Med temat program och praktik vill vi särskilt uppmana forskare att reflektera över vad som sägs och vad som görs inom hälso-, medicin- och sjukdomsrelaterade verksamheter, såväl i nutid som i det förflutna. Med program avses till exempel vårdpolitiska uttalanden och viljeyttringar av olika slag, beskrivningar eller bilder av hur t.ex. vård och omhändertagande bör vara beskaffad, läroböckers besk
Renewable energy sources (RES), such as biomass, can be used to address two important issues in Europe: climate change and energy security. If biomass is produced sustainably and used efficiently, bioenergy contributes very little to CO2 emissions. The overall objective of the work presented in this thesis is to provide a scientific basis describing how bioenergy can play a fundamental role in the
Popular Abstract in Swedish Människans kropp består av celler som byggs upp av komponenter som DNA, proteiner, lipider och polysackarider. I DNA finns den genetiska informationen lagrad som gör att kroppen kan fungera. Informationen i DNA omvandlas till proteiner som deltager i cellens biokemiska processer. DNA finns i olika former, dels genomiskt DNA och dels en mindre cirkulär form som kallas plThe main scope of this thesis has been to study and develop new purification methods and also to further develop existing methods for purification to enhance their efficacy. Important parameters in the development of the methods are that they should be suitable for scale-up and possible to be integrated into recovery processes. The studies in this thesis describe that a hydrophobic peptide tag ca
Evaluation of the effects on road safety of an incident warning system on the IP5 road in Portugal was carried out. Video data at two sites was collected before and after the activation of the warning system. Conflict observations revealed that there was no major change in safety between the before and the after period.
