En rörig historia : en fallstudie över Secorocs processflöde av DTH-rör
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.
Torrefaction of biomass : a comparative and kinetic study of thermal decomposition for Norway spruce stump, poplar and fuel tree chips
Stump biomass is energy rich and stump harvesting for use as fuel become more and more
interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in
Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not
been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of
stump are probably of great importance to make it accepted as fuel. It is therefore rewarding
to carry out an investigation in this area for stump.
This report represents results from a diploma project, which was aimed to develop a fixed bed
reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic
modelling employing Ozawa method and different kinetic models including one-step and
three-pseudo-component models.
Teoretiska perspektiv på musik och insomning - En musikvetenskaplig litteraturstudie om möjliga förklarings- och förståelsemodeller
This essay constitutes a literary study investigating how scientific literature within thefield of musicology can benefit to the understanding of how people use music as anaid for sleep and relaxation. Furthermore it aims to answer the question of whatconclusions can be drawn about the music people choose to use in these types ofsituations. The essay depicts the phenomenon of sleep music from several anglesgathered from the literature and investigates several models of understanding howand why people use music as a tool for emotional influence. As a complement to this,and to illustrate the modern usage of music for mind-altering purposes, the essay alsostudies a selection of digital sleeping aids ? apps.The study shows a complexity since the phenomenon can be viewed from severalangles that are not always consistent with each other.
Heel Me
High heels ? a fashion that has not gone out of style after hundreds of years. Despite their esthetic advantages, high heels become uncomfortable and harmful after repetitive and long term use. With this as a starting point, Huyen Nguyen ? a student at the Innovation Engineering Program at the University of Halmstad ? decided to make a final thesis project.
The project goal has been to combine the esthetic advantages of high heels and bring a comfortable solution to the equation.
Den europeiska identiteten : Komparativ studie mellan kommissionsordförande Barrosos syn på Europeisk identitet och EG/EU:s tidigare officiella hållning
What is the European Union (EU) and which countries should be part of it in the future? These questions became topical during the first part of the 21st century when political and geographical changes hasten the need to decide the nature of the European cooperation. In the European Constitution, that never come into force, the European values that a key role but was taken away in the succeeding Lisbon Treaty. Nevertheless EU continues to expand, recently to the East and non-European countries asTurkey are now on the ?waiting-list?.
Lean Production i ett byggprojekt : Kan Lean Production ge fördelar i byggbransschen?
Detektion av gasläckor används i en mängd olika applikationer som till exempel kvalitetskontroll av kylskåp, lokalisering av skador på kablar och lokalisering av bränsleläckor i bränsletankar.Denna rapport undersöker förbättring av detektionsalgoritmen i en existerande vätgasdetektor.CUSUM algoritmen är en enkel men kraftfull metod för att snabbt detektera små ändringar i nivån av en signal. Denna metod är anpassad till det dynamiska beteendet i sensorn som används för att spåra vätgasläckorna och även utvärderad på omfattande mätningar utförda på läckor med kända storlekar. Resultaten visar att användning av den föreslagna detektionsalgoritmen innebär en betydande ökning av detektorns prestanda. Särskilt bra blir resultatet på små läckor..
En studie av två invänjnings-modeller i förskolan. : 3-dagars och två-veckors modellerna
I have made a research about two different methods for introducing small children to Nursery School/Kindergarten. I choose to do this as I have found very little about this in the literature we have studied during my education to become a pre-school teacher.This period in the life of very small children and their parents is a big change in their daily life. The more traditional way to start pre-school is to do it very gradually during two weeks, the two-week method. This means that the parents visit the pre-school together with their child for a very short time, about one hour the first day. After one week they leave their child with the staff for about an hour and at the end of that week they try to leave it full time (6-8 hours).
Virtuellt ledarskap i näringslivet: Hur affärssimulering kan skapa kompetens, samsyn, och ökad ekonomisk förståelse i en organisation
The purpose of this thesis has been to explore the topic of business simulation from a theoretical foundation in social constructivism and theories concerning leadership as the management of meaning. The most important findings are that business simulation can be used for strategical leadership by management to create a common vision in the organisation members, which affects their perception of the business and the decisions and actions they make, which in turn can lead to a more efficient organisation that becomes better at meeting set goals. This can be viewed in different ways from different theoretical viewpoints: as inducing targeted changes in mental models to create changes in decision making and actions; as a secondary socialization process where the vision of management is externalized as a business simulation that is in turn internalized by the organisation members that participate in the business simulation, or as a way to frame and define the reality of the organisational members which creates a shared reference point against which a feeling of organisation and direction can emerge. In the future, business simulations may become increasingly used by organizations to create a common vision or to communicate a new decision to the organization members..
Kan konsumentförtroende användas för att prognostisera konsumtion i Sverige?
Making accurate predictions of private consumption expenditures is a difficult task. This thesis examines if consumer confidence can be used to forecast consumption. Using regression analysis, the link between consumer confidence and private consumption expenditures is analyzed for Sweden between the years 1994 and 2005. Two different models are estimated. In the first model consumption is regressed only on consumer confidence, while model two is extended to contain more variables.
Olika modellering av vårdprocesser utifrån metaforiska perspektiv : ? Skapar det nya drivkrafter för processutveckling?
The study was conducted in Jönköping County Chamber of fibrillation and is about change and improvement of process modeling technology. The process for treating patients with fibrillation is in the need to evolve and improve. In order to develop the care they needed a current state description which usually is made with the traditional process modeling tool.Many scientists and health professionals is in the opinion that this technology gives a too rigid image to describe the care processes. It also does not sufficiently take into account the human aspects. This reasoning suggests that the process modeling technology in healthcare is in the need to develop multiple perspectives.

Young men who commit sexual abuse is a complex topic. This study is based on litterature on the subject and the material is processed through a qualitative content analysis. The study aims to study how the litterature describes the reasons why young men commit sexual abuse. It also aims to explore what is described to be effective treatment of young men who committed sexual abuse. The study found that most of the young men who commit sexual abuse comes from families where violence and psycohological abuse occurs. Many have themselves been victims of sexual abuse.
Kalkylens Roll i Lean Production : en studie inom svensk fordonsindustri
Bakgrund: Lean Production uppkom som ett verktyg för att sänka kostnader och därmed öka konkurrenskraften på en allt mer hårdnad marknad. Synen på processtänkande och dess möjligheter har under senare årtionden ökat markant i intresse, däremot har ekonomisystemen inte förändrats i samma takt. Granlund (2001) menar att trots det starka trycket att förändra kalkyleringen använder många företag sig fortfarande av traditionella påläggskalkyler med direkt lön som fördelningsbas. Kaplan & Johnsson belyste redan 1987 problemet och argumenterade för hur traditionella kalkylsystem ger en allt för aggregerad och snedvrängd bild av verkligheten. Den debatt som uppstod är känd under namnet Relevance Lost.
BI M i förvaltningsskedet med avseende på konstruktion.
Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.
Affärsmodeller och Strategier i Apples Appstore
Apple has since their launch of the Iphone series created a billion dollar business with the market place Appstore. Third-party apps have disrupted the mobile industry, attracted a high number of developers and set the standard for the industry. Despite success, this market has yet not been the topic of any academic study, a fact that makes this thesis important. Under the assumption that apps can be regarded as a service, traditional service marketing theories have been applied with the research goal to map existing business models, evaluate revenue potential and understand best practices of marketing techniques. A series of qualitative interviews with representatives from the difference business models, backed by secondary data describing the domain shows how the Appstore has evolved over time and which marketing practices that appear successful.
Lean Productions påverkan på ekonomistyrningen : En fallstudie inom Gnutti Powertrain AB
Examensarbete, civilekonomprogrammet, Ekonomihögskolan vid Linnéuniversitetet, ekonomistyrning, 4FE03E, VT 2013Titel: Lean Productions påverkan på ekonomistyrningen - En fallstudie inom Gnutti Powertrain ABBakgrund: Allt mer konkurrensutsatta marknader har inneburit att företag sökt nya sätt att utveckla och effektivisera sina verksamheter. Detta har resulterat i att många företag valt att införa produktionsstrategin Lean Production. Flera forskare har påvisat att den traditionella ekonomistyrningen inte är anpassad till och lämplig för företag som använder produktionsstrategin Lean Production. Detta har inneburit att den traditionella ekonomistyrningen måste förändras och utvecklas för att kunna stödja de förändringar som den nya produktionsstrategin ger upphov till. Därmed blev det intressant att studera ett enskilt fallföretag för att identifiera om och hur detta företag har förändrat sin ekonomistyrning till följd av användandet av Lean Production. Syfte: Syftet med denna studie är att utifrån det enskilda fallet Gnutti Powertrain AB bidra med en förståelse för hur ekonomistyrningens utformning och användning påverkas av användandet av den avancerade produktionsstrategin Lean Production.
