Portrycksvariationer i lera - Simulering av portrycksvariationer i leror underlagrade av friktionsmaterial
This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.
Det goda värdskapet : en fall studie på Västerås
Västerås är en stad som tidigare har förknippats med gurkor och industrier då ASEA, nuvarande ABB etablerades i Västerås 1883. Staden är idag relativt okänd för externa gäster, det är något som Västerås marknadsföringsorgan Västerås & Co vill ändra på. Arbetets syfte är att undersöka vad en värdskapssatsning kan ge för effekter på turismen och näringslivet i Västerås samt undersöka möjligheten att värdskapscertifiera de olika verksamheterna i Västerås. Litteraturstudier, intervjuer samt deltagande observationer har använts som metod. Teoriavsnittet tar upp värdskapsbegreppet samt samarbeten inom organisationen för att sedan kunna jämföras med resultatet från intervjuerna och de deltagande observationerna.
Praktisk kompetens i projektering
Denna rapport är ett examensarbete av mig, Per Johansson, och beskriver det företag och den arbetsplats som jag tillbringat min verksamhetsförlagda utbildning (VFU) på. I examensarbetet ingår det att ta upp ett problem och presentera en eventuell lösning på problemet.Jag hittade inte något specifikt prroblem att skriva om på den arbetsplats jag varit på utan jag har försökt att beskriva vad vissa personer inom arbetsledning på bygg och anläggningsföretag ofta upplever som ett problem angående hur projekteringen fungerar. Efter att jag intervjuat ett antal personer på flera olika företag så visade det sig att de flesta tycker att det saknas praktisk kompetens i vissa projekt när man projekterar. Det leder till att de både kan vara svårt att utföra projekten ur ett arbetsmiljöperspektiv och även rent byggtekniskt. Detta är olika beroende vad det rör sig om för typ av projekt.

EMC problematik och el-kvalitet i elkraftnät
The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.
Aggressivt utagerande: Betydelsen av samtidig förekomst av callous-unemotional traits och impulsivitet
Abstract The importance of the co-occurrence of callous-unemotional traits and impulsivity concerning aggressive acts was examined by a survey. The participants consisted of 1478 Swedish youth. Three groups with extreme scores on callous-unemotional traits and impulsivity was identified. The group scored high on both was more prone to show higher levels of aggressive and conduct problems behavior compare to the other groups. The aggressive and conduct problem behavior was shown at higher level in all examine variables. This study highlight that impulsivity can identify extreme aggressive individuals, without taking HIA (Hyperactivity, Impulsivity and Attention) problem as a entirety, to account, if shown with callous-unemotional traits. Keywords: Callous-unemotional traits, impulsivity, aggressive, conduct problem, youth, co-occurrence..

Sociala omsorgsassistenter : de "nya" omsorgsgivarna i en omsorgsförvaltnings "paradigmskifte"
Purpose: The primary aim of the study was to analyse and discuss how employees with a secondary nursing education describe their occupational character whilst working as well as the conditions for caring acts in a changing progress towards professionalism.Questions: What are the conditions to provide a high standard of care in this changing progress? What influence does it have on the occupational character ?Method: Critical case study and focus groupsConclusion: One of the central findings of the field study was the identification of two occupational identities; traditional and pedagogical orientated. These two occupational character traits are connected with different types of occupational competence and demands different theoretical knowledge. They also have different regards concerning the new title; social omsorgsassistent. A conclusion of the study is that a professional project of a non-specific nature is unable to stress the diffeRent levels of knowledge and competence that occupational identities have when one seeking professionalism..

Vår uppgift är att få dem att vilja.
Syftet med vårt examensarbete har varit att ta reda på hur erkänt duktiga lärare arbetar med kommunikation som en del av det pedagogiska handlandet, samt vilken syn de har på eleven både ur ett kunskapsperspektiv och ur ett rent mänskligt perspektiv. Vi har använt oss av en kvalitativ studie där vi valt att observera tre av de lärare som medverkade i Tv-dokumentären Klass 9A på Dvd. Innan vi gjorde vår observation skaffade vi oss en utökad förförståelse genom att ta del av vad både forskning och annan relevant litteratur tar upp inom området kommunikation, skolan som demokratisk arena samt lärarens yrkesroll.Resultatet av vår studie visar att det finns några saker som är viktiga för att skolan ska bli en plats där elever känner trygghet och lust till lärande. Kommunikativ kompetens, ett genuint intresse för eleven och ett personligt engagemang bildar den helhet som enligt oss, behövs för att lärarna skulle kunna skapa goda relationer med eleverna. Dessa relationer anser vi vara mycket betydelsefulla för att elever ska utvecklas både kunskapsmässigt och på det personliga planet..
Smartphones på arbetsplatsen : En studie av smartphones påverkan på effektivitet och välmående bland yrkesverksamma människor
In todays society IT in general and the Internet in particular are given elements in people´s everyday lives, and smartphones has come to be a big part of those elements. This study focuses on how the use of Smartphones in particular influences the individuals in their working environment, and how this use influence the efficiency and the well-being of said individuals. To answer our research question regarding how said use comes to effect the efficiency and the well-being for proffesionals in their working environment we have used data from qualitative interviews who is enriched by a short initial diary study. This data has then been analyzed using the Affinity Diagrams Technique, leading to four central themes emerging from the data. The results show that smartphone use at work comes with both positive and negative effects; efficiency increased through the use of smartphones due to the great versatility that comes with the technology, while in terms of well-being issues of stress emerged.
