Identifiering av synkronmaskinsmodell genom SSFR-test
At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.
Effektiv ordinlärning? : En studie av aktiv ordinlärning i engelska inom gymnasieskolan
The purpose of this essay is to discuss and compare different ways of learning new words and expanding your vocabulary in a foreign language. This is done by an examination of relevant literature and available research, as well as by an empirical study with two upper secondary school classes, in which two different methods are put to the test: one traditional method of the kind that is found to be most common in second language acquisition, and one designed to take existing research into account. The results show that, although effective in the initial stages of acquisition, the traditional method, where words are learned in isolation and via translation to L1, results in a very limited form of knowledge. A big part of the words acquired via this method is also forgotten soon afterwards. The other method, where words were learned and tested in its proper context, was found to result in a broader form of vocabulary knowledge, covering more aspects, and that remained over time.
Automatisk test för myoelektroder.
Denna rapport avhandlar en tio veckors period på Otto Bock Scandinavia AB i Norrköping. Där analyserades en manuell testutrusning för funktionstest av myoelektroder, för att mäta muskelspänningar. Myoelektroderna används till att styra gripfunktionen hos handproteser, för patienter som förlorat en del av sin arm. Analysen ska resultera i att ge ett förslag på en automatiserad test av elektroderna. En stor del av rapporten består av studier kring hur testmetoderna fungerar och elektrodernas användning och funktion.
Affärsmetoder, ett undantag ifrån patenterbarhet? -En komparativ studie av USA, Europa och Sverige

Automatiserad unit testning
Dagens utveckling av mjukvara går snabbare och snabbare samtidigt som mjukvaran blir allt mer komplex. Att under dessa omständigheter kunna bibehålla en lika om inte högre kodkvalité är en utmaning. På UIQ bestämde de sig för att undersöka om ett automatiserat unit test kunde hjälpa dem. Metoderna för att komma fram till resultaten i denna rapport har varit intervjuer, en enkät, intern information och litteratur så som forskningsartiklar m.m. Denna rapport är en utredning av automatiserade test, vad man bör tänka på, vilka fördelarna är, vilka testfall som är möjliga att automatisera med mera.
Representativa testnät försvenska eldistributionsnät
This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.
Lärande - styrt eller i samspel? : En studie om lärares syn på undervisning och lärande
This study?s purpose was to examine which main forms of teaching methods that occurs in the Swedish nine-year compulsory school and how often learning through social collaboration take place. The study contained literature and interviews with eight teachers. Our research-questions were: What is the teacher?s opinion about different teaching methods, their opinion about learning and teaching and if there were any difference between the teachers teaching younger or older students regarding teaching methods? Our conclusions of this study were that ?lecture-methods? is the most common among teachers.
Ljudlandskapets Attribut: Metoder för att bättre förstå och beskriva ljudlandskap
In soundscape research, the field?s methods can be employed in combination with approaches involving sound quality attributes in order to create a deeper understanding of sound images and soundscapes and how these may be described and designed. The integration of four methods are outlined, two from the soundscape domain and two from the sound engineering domain. This study has shown that by combining these methods the understanding of both the entire soundscape and the specific sounds increase. The study also shows that when the methods are used, there is a qualitative change of the description and understanding of soundscapes and the concrete description becomes more elaborate..

Tre lärarperspektiv : En studie om olika arbetsmetoder i förberedelseklass och i ordinarie klass
The Swedish school reflects the society that we have today, a society with many different ethnical and cultural backgrounds. The purpose of this investigation is to study how the school is working with children that recently immigrated to Sweden. What kind of methods are they using at school, to get the best development as possible? Do the teachers manage to be concerned of the students in the school? What kind of reception do these children get in the school? What methods are the teachers using? And are these methods really the best to use to enhance the language and cognitive development of these students?The methods I have been using to examine these questions have been qualitative. I have interviewed three teachers about their everyday work in a multiethnic school south of Stockholm.

Reagerar grisar immunologiskt mot foderproteiner? :
The aim of this study was to detect antibodies in swine serum against proteins in soy beans, wheat, oat and barley. Two methods were used: agar gel immunodiffusion test (AGID), and SDS-PAGE followed by immunoblotting. The sera examined originated (I) from piglets younger than one week (negative control), (II) pigs from a feed trial with soy bean in a herd with PMWS, and (III) pigs inoculated with Brachyspira hyodysenteriae and Escherichia coli after being fed with soy. The AGID-test was negative concerning all examined sera which were analysed against proteins in soy bean, wheat, oat and barley. In the experiment based on immunoblot antibodies were demonstrated within all three groups of examined pigs.
