SMED implementation vid slipoperation
The thesis has investigated how Sandvik Coromant could implement the SMED principle on one of their grinders groups and what improvements it would lead to. The aim of the thesis is to identify the current situation and investigate how their setup times would be affected by SMED. The work initiated with a literature analysis about the SMED principles and then proceeded with an analysis of the current situation where the activity was time mapped. The analysis consisted of time trials of the process that the thesis would include. The time studies revealed opportunities for structural improvements to create environment for a more structured process.
Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

?Hur länge kan man vara i fas 3 egentligen?? : En kvalitativ studie av deltagares upplevelser av fas 3 i Jobb- och utvecklingsgarantin
The purpose of this study was to examine what participants in the third phase (fas 3) of the Swedish unemployment program, Jobb- och utvecklingsgarantin, think about their situation, what they think about the program and if they feel stigmatized due to their unemployment. The data for the study was collected at one of the organizers of the program, which provides an introduction program for the participants. A qualitative method was used and the data was collected through six semi-structured interviews. The results were analyzed using Antonovskys theory of Sense of Coherence (SOC). The conclusions of the study were that the participants felt support from the staff at the organizer.
Lärarstudenters upplevelse av utbildningens förmåga att förbereda dem för undervisning av andraspråkselever : En intervjustudie med blivande lärare i samhällsvetenskapliga ämnen
This study aims to investigate how a number of students who are at the end of a teachers? educations program in social studies, geography, religion and history interpret that the national curriculums states that every teacher is responsible for students language development and should be supportive of language backgrounds. In the light of the curriculums the study explores how the teacher education students feel that the education has prepared them for teaching children with Swedish as a second language. The study also examines how the teacher education students think that the teacher education could improve in matters like preparing future teachers to teach social studies, geography, religion and history to second language children.The study is based on interviews with seven university students and shows that they feel a responsibility to develop their future students? language.
Behandling av fetma : Effekter på BMI, midjemått, vikt, ?Känsla av sammanhang?, kroppsuppfattning och självupplevd hälsa

I en annan del av skolan : Hur elever under ett år på IV-programmet hittar sin studiemotivation
Under vår utbildning kom vi i kontakt med det individuella programmet på en skola där 82% av en årskull gjort sig behöriga till ett nationellt program. Det väckte vår nyfikenhet. Studiens syfte är att ta reda på vad som bidragit till att eleverna blivit studiemotiverade. En hermeneutisk undersökning har gjorts där både kvalitativa och kvantitativa metoder har använts genom intervjuer och enkäter. Resultatet visar att det inte är en tillfällighet att så många blir behöriga att söka ett nationellt program efter ett år på den undersökta skolan.
Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods
for estimation of the down channel (base station to mobile subscriber) in
Wide-band Code Division Multiple Access (WCDMA).
The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is
a conventional method that bases the estimates on data that is known to both
sender and receiver, so called pilots. The second method, Decision Directed
Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data
for estimation.
Simulations show that DDCE, in comparison to OFCE, does not attain an
improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An
improvement is only seen when the BER becomes much lower than what is common in
real situations.
In conclusion DDCE is complicated, involves many mathematical operations and
gives insignificant improvement of SNR when BER takes common values. It is
legitimate to question if it is possible to use the method in a real mobile
phone system..
Organisationskultur samt avvikelse- och förslagshantering för ständiga förbättringar i tjänsteverksamheter : Fallstudie Vägverket
Because of an increasing demand from customers and changing external environment, there is a need for continuous improvements, for both manufacturing and service organizations, to meet these demands. Manufacturing organizations have been working systematically with quality improvements for a long time, but it has not been as common for service organizations. Because of that the methods to use for implementation of the systematic improvements have not been designed to fit service organizations, and not either for public organizations. The purpose of this thesis is to explain if and why the Swedish Road Administration?s organizational culture and handling of ideas and deviation support an implementation of continuous improvement management.
Emballage för väggelement i trä : Paketering, hantering, lager och transport
As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

Abstract Title: A messy story ? a case study of Secorocs process flow of DTH-pipes Presentation date: 2010-06-02 Course: Bachelor thesis in businessAuthor: Kristoffer ForsmanAdvisor: Kjell GustafssonKeywords: Management control, process control, lean production, process flow analysisPurpose: The purpose of this bachelor thesis is to develop an overview of the process flow for a specific product, and with the help of this mapping based on a lean production philosophy show possible improvement proposals and how these can lead to a more efficient process flow.Methodology: I have used a case study of Secorocs DTH-pipes and my primary data are gathered through interviews and observations. I have used theoretical framework to establish a process flow analysis. This is to obtain data on process activities and whether they are creating value or not. This leads to a current mapping of the situation in Secoroc on DTH-pipes and then analyzed and suggestions for improvement are developed.Conclusions: That by using the above mentioned mapping of process flow of DTH-pipes, problem areas could be illustrated.
Kunskap under utveckling : En enkätundersöking på gymnasiets praktiska program.
Syftet med studien var att mäta elevernas kunskaper inom området evolution på yrkesförberedande program. En enkät delades ut till elever på en gymnasieskola med frågor som hade fasta och öppna svarsalternativ. Ett statistiskt test (Kurskal-Wallis) användes när materialet tolkades. De alternativa evolutionsidéerna dominerade svaren på flersarsfrågorna medan det hos de öppna frågorna var en dominans av vet ej/ingen aning svar. Det fanns ingen skillnad på rangen hos enkätfrågorna med öppna svar och intresset av att läsa naturkunskap b eller biologi.

Språkskillnader mellan Java och C# : En kvantitativt jämförande studie
Java och C# är två objektorienterade programmeringsspråk med många gemensamma egenskaper, dock har dessa egenskaper syntaxmässiga skillnader. En tidigare undersökning har visat att mindre än 5 % av källkoden behöver ändras för att konvertera ett fungerande Java-program till ett likadant fungerande C#-program. Frågeställningar baserade på denna upptäckt togs fram och besvarades genom att jämföra två identiska program skrivna i Java och C#, skillnader och likheter mellan programmens källkod pekas ut och sammanställs kvantitativt. Skillnader består av bl.a. språkens nyckelord, klasser och metoder som motsvarar varandra i språkens bibliotek har olika namn och beteenden samt att finesser som finns i ena språket återfinns inte i det andra.
