Risk analysis and a study of risk awareness and risk communication at LEAF Gävle concerning dust explosions
The purpose of this report is to study the risk of dust explosions at the candy manufacturing plant Leaf Sverige in Gävle, Sweden. The risk analysis was conducted with a preliminary hazard analysis, PHA and event trees. The analysis focuses only on the risk posed to employees and material damages at the plant. No third person injuries have been considered. Another purpose of this report is to study risk awareness and risk communication concerning dust explosions.
Självkompakterande betong vid platsgjutning av anläggningskonstruktioner
By using modern methods of casting concrete, cast in place can get more effective and industrialized. A modern method is self compacting concrete. By using this type of concrete, advantages like improved working environment and rationalized construction can be reached. Because the concrete doesn?t need to be vibrated, the amount of staff on site and the noise can be reduced.

Drivenhet för satellitantenner
The task in this master thesis was to design and construct a prototype of a satellite antenna driver unit. The unit is to be robust and work in cold weather down to -40°C, so that it can be mounted on the roof of a minibus. A microcontroller controls the H-bridges simultaneous, each connected to an electrical motor. Hardware and software protections were implemented to ensure that the antenna can not turn outside its allowed area and risk breaking. The unit can output voltages at many different levels and communicate at a multitude of signal standards..
RO hantering på ABB, TPE
Arbetet har utförts på ABB i Ludvika med avsikt att förbättra revisionsprocessenför kontroll och skydd. En revision är en ändring på ett godkänt och klarmarkeratobjekt. Då objektet i fråga redan kan vara levererat till kund och man behöver göraen ändring krävs en strukturerad process för att utföra denna ändring. Processen föratt göra detta är i dagsläget komplicerad och kräver en hel del administrativt arbete.Processen använder sig utav ett antal program för lagring och databaser så som,Lotus Notes, HiDraw Studio, och HiDra32.Avdelningen för kontroll och skydd är i fasen att övergå till ett annat elCADsystem, Engineering Base. Detta är också en av anledningarna att man önskar en nyprocess för revisionshantering.Arbetet bestod till en början av inlärning av den dåvarande processen.
Yrkeselevers svenskkunskaper 1977 och 2014 : En studie av två elevgruppers resultat på ett centralprov
The aim of this study is to investigate how the Swedish language proficiency of pupils in vocational programmes in 1977 was measured and assessed with the aid of a national achievement test, and to investigate whether vocational pupils today, in 2014, have similar language proficiency to that of pupils in the 1970s. The study also discusses how the design of the national achievement test from 1977 reflects the view of knowledge that prevailed in society and in the policy documents. The material for the study consists of a total of 75 national achievement tests, 40 of which were taken by pupils on a vocational programme in 1977 and 35 by pupils on a vocational programme in 2014. The national achievement test consists of two parts, the first of which focuses on isolated elements of language proficiency, while the second involves free text production. The material was analysed quantitatively in accordance with the correction material from 1977.
Möjligheter och problem med integration av hanteringen av antagonistiska och olycksrelaterade risker - En jämförelse med utgångspunkt från två konsultföretags arbetssätt
The aim of this report is to investigate, on the basis of two consult agencies perspectives, what the possibilities and obstacles are to integrate the work with antagonistic and accident related risks. The report is based on two consult agencies where each agency´s work procedure is represented by a risk management method. The work with accident related and antagonistic risks is analysed and evaluated compared to four different components. The components are risk management process (IEC´s and FEMA´s model), driving forces, education and competence, and resources to control risk management with COSO?´s ERM framework.
Från ett användarperspektiv : underlättar use case kommunikationen angående krav och behov i kravhanteringsprocessen?
Examensarbetets frågeställning berör användarnas medverkan i Requirements Engineering (RE). Under RE-fasen skall samtliga krav på det kommande systemet tas fram från intressenterna. En viktig intressentgrupp i kravutvinningsarbetet är de kommande användarna av systemet. Resultatet av RE-fasen är en viktig faktor som påverkar hela den fortsatta utvecklingsprocessen samt hur lyckat det slutliga systemet blir.Detta examensarbete innebär en undersökning av vad användarrepresentanterna anser om use case-modelleringen i RE-processen. Undersökningen har påvisat att användarrepresentanterna är positiva till use case-modellering som arbetsmetod för att kartlägga kraven.
Hörapparatbärares upplevelser och erfarenheter av tekniska hörhjälpmedel i offentliga lokaler
To be able to feel a sense of belonging, people need to have the possibility to take part of the information from the society. Hearing-impaired don?t have the same possibility as hearing people when they want to take part of the information, therefore they don?t get the same benefit. This contributes to a feeling of not belonging and a sense of limitation in different social occasions. Therefore the society needs to be accessible to everyone regardless disability.
Digitalisera loggboken : En analys av utmaningarna med att utveckla IT-stöd för kunskapsintensiva verksamheter
Failed system development projects are a common sight within the IT-industry. During the last ten years we have seen several more or less disastrous high profile projects being reported in the news. One aspect that might hold some of the responsibility for these failures is the fact that more organisations are knowledge intensive which makes their work processes difficult to capture in computer systems. How requirements engineering is handled becomes even more important in these cases, where processes are unpredictable and rely on individual judgement and knowledge. In this study we have examined the challenges of developing systems for knowledge intensive businesses through a method of qualitative case study of a university laboratory.
"Programmet har ju en låg status" : Gymnasielärares tankar och attityder om elever på yrkes- och studieförberedande program
This paper is named ?The status of the programme is low? ? Gymnasium teacher?s thoughts and attitudes towards students in the vocational- and the educational programmes. The purpose is, as the title reveals, to examine the attitude of four teachers in the Swedish gymnasium towards the vocational and the educational programmes and the students that attend either one of them. This purpose is accompanied by research which says that the educational programmes? status is higher than one of the vocational programmes.
Värdering av katastrofers miljökonsekvenser
When a disaster occurs the main focus is on the loss of human lives. Here the environmental effects have been in the centre of attention. This work has had two main purposes. The first one was to formulate attributes, variables that together present a complete picture of the consequences that an event has had on the environment. The other main purpose was to investigate how people value the impact that a disaster can have on the environment.
Undervisning i informationssökning. Diskursiv praktik i två gymnasielärarlag.
The aim of the present thesis is to examine discourses about teaching information seeking in upper secondary school teachers. The main questions are: (1) What different interpretative repertoires can be identified among teachers talking about teaching information seeking in relation to students? problem-based tasks? (2) How are these repertoires constructed and what functions can be observed? The theoretical framework is discursive psychology. Two teacher teams from two different upper secondary schools in the Gothenburg area participated in focus group interviews. Group A consisted of four teachers from the Individual Programme and group B of seven teachers from the Social Science Programme.
