The dynamic testing method, as an alternative to traditional bench testing against a brake, has proven to be a fast, convenient, yet accurate way of characterizing electrical machines. By measuring the speed and the currents and voltages while alternatively accelerating and decelerating the electrical machine it is possible to obtain its torque and flux linkage characteristics dynamically. This ar

Denna rapport tar fram publikens röster i samband med utställningen Petroglyfiskt Virtuella upplevelser kring hällristningar (maj 2013-december 2014) vid Österlens museum i Simrishamn. Rapporten är en fallstudie som belyser ett pilotprojekt och forskningsexperiment kring publikens möte med interaktiv digital teknik och konst i ett kulturarvssammanhang, samt besökarnas reaktioner på interaktiva och

This report has been written at the request of The Swedish National Committee for Psychology at the Swedish Royal Academy of Sciences and it provides an account of the external research funding at the six large university departments of psychology in Sweden during the years 1995, 1997, 1999 and 2001. First, an overview of the six departments is given with respect to the amount of research funding,

Popular Abstract in Swedish I inledningen till avhandlingen görs tre viktiga antaganden som sedan kommer att ligga till grund för all vidare argumentering; (i) för det första görs ett (i sammanhanget kontroversiellt) ontologiskt antagande. Det antas att troper (dvs. partikulära egenskaper) existerar; (ii) för det andra antas (återigen kontroversiellt) att troper är det enda som existerar (åtminstoThe treatise attempts to approach and deal with some of the most fundamental problems facing anyone who wishes to uphold some version of the so-called theory of tropes. Three assumptions serve as a basis for the investigation: (i) tropes (i.e. particular properties) exist, (ii) only tropes exist (that is, tropes are the only basic or fundamental kinds of entities), and (iii) a one-category trope-t

En medievärld i förändring och ett ökat individuellt ansvar för sökning, värdering och sammanställning av information i skolan väcker frågor om hur elever, lärare, skolbibliotekarier och deltagare i sociala medier hanterar källkritiska frågor och trovärdighet. I våra studier av klassrumsaktiviteter och av deltagande i Wikipedia framkommer en komplex relation mellan preferenser för förhandsgranskad

In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this “chemic

This thesis is a study of the mountain vegetation in the Faroe Islands based on five altitudinal transects sampled during the period 1999-2001. The vegetation was studied on the basis of plant communities, life-forms and biodiversity of vascular plant species and is discussed in a climate change perspective. The boundary between arctic and temperate vegetation is established and the tolerance of c

MAX-lab is replacing its microtron injector with a RF-gun driven 500 MeV recirculator linac (250 MeV linac with one recirculation). The linac will later be equipped with a low emittance laser gun. In this paper, a future installation of a superconducting undulator driven by the recirculator beam is discussed. The undulator is characterised by the emission of spontaneous undulator radiation.
