Förändringsarbete mot en resurssnål tillverkning : Lean production i ett svenskt tillverkande företag
Vilken strategi ett tillverkande företag arbetar efter kan variera och bero på en mängd olika faktorer. En effektiv tillverkning kan bli komplicerad när marknaden efterfrågar allt mer skräddarsydda produkter med varierande egenskaper. För att bemöta denna typ av komplexitet finns en rad strategier och modeller som har fått global spridning. En av dessa strategier är lean production, ett begrepp som vuxit fram utifrån studier genomförda på den japanska tillverkningsindustrin.I denna studie undersöktes varför lean production valdes som styrningsfilosofi i ett svenskt tillverkande företag, vilka förändringar detta inneburit samt vilka åsikter som fanns kring förändringsarbetet. Insamling av empiri har skett genom att genomföra en fallstudie på företaget Trioplast Sifab.
Utformning & placering av vädringskanaler i ett passivhus, drivet av naturliga krafter
A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.
Skogs påverkan på vindkraftsproduktion - en fallstudie av vindkraftverk vid Andersfält.
The purpose of this master thesis is to investigate how nearby forests affect the energy production in wind turbines. To reach the purpose a case study is performed on three wind turbines sited on a field in a north-south line at Andersfält in the municipality of Halmstad, Sweden. Approximately 100 meters south of the southern wind turbine a forest is situated. The case study is divided into three sub studies where the difference in energy production, the affect of the forest and a wind meteorology model, WAsP, is studied. The result show that the forest have a significant influence and that the WAsP-model gives an incorrect result of the energy production in wind turbines sited near a forest..
Livscykelanalys av sex olika fiskodlingssystem : Fiskens miljöpåverkan för konsumtion i Stockholm
This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.
Riskfaktorer för uppkomst av neurologisk sjukdom vid infektion med EHV-1
During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.
Hur kan vi utveckla vårt personliga uttryckssätt med ljud?
This is a bachelor thesis that studies and discuss the question: How can we develop our individual narrative technique with sound design in a Swedish drama production? We have done research and empirical studies. We have analyzed movies to get an idea how we use the sound design in Swedish drama productions today. We have produced a movie that gives sound the biggest part. Key words: Swedish drama production, narrative technique, sound design.
Miljöpartiet - ett parti i förändring : En komparativ textanalys av Miljöpartietspartiprogram mellan 1994 och 2005
Following changes in society and other influences, the ideology of political parties can evolveover time. For example, theories exist claiming that all parties in Sweden strive towards the"middle".A good example of a political party in Sweden which recently has gained entry toparliament is the Swedish Green Party (Miljöpartiet, MP).MP was initially influenced by a green ideology (ecologism) which started as a globalmovement stating that no other ideologies shared their concerns about the environment. Thegoal of the ideology was to, via an increased influence within the political system and throughsmall-scale production, increases both natural values and people's well being. By becomingelected into parliament it is plausible that the ideology of MP could have changed due to theinfluence of for example, the realities that parliamentary every day represent.The aim with this essay was to study the changes in MP's party program from the yearof 1994 and the most recent, to see if any changes have occurred related to MP's officialideology. The study was conducted using a comparative text analysis.

Samband mellan tidig ålder vid avskiljning och missriktat diande hos föl :
By tradition horses are weaned at an age of 5-6 months. This study illuminates weaned foals misdirected suckling behaviour, which means that they try to suckle another foal. Since no information about this issue is presented, we decided to perform a behaviour study on weaned foals. The misdirected suckling behaviour was studied on a group with 7 foals, with both fillies and colts. In the group the weaning age varied between 147 days and 215 days, and the first time we observed them, they had been separated from the mares for 12 days.
Energianvändning på Volvo Lastvagnar Tuve
Volvo Trucks is the second largest manufacturer of heavy trucks, with factories in several countries and with around 21 000 employees. At the plant in Tuve, trucks have been built since 1982 and the activity mainly consists of producing side members and to assemble and packing kits of trucks. In 2005, the factory in Tuve launched the ambition to be the first carbon dioxide neutral vehicle factory in the world. This will be implemented by streamlining and investing in renewable energy. The aim of this degree thesis is to map the usage of energy within production, and also to prepare a method to measure key figures (use of energy per produced unit).
Med Lean i bagaget - En studie om Leans förmåga att öka produktiviteten av en bagagehanteringsprocess
Although Lean has received an increased amount of attention in the service context, research still has not established how successfully Lean manages to increase service productivity; since service productivity consists of both efficiency and quality. Research regarding productivity discusses the risk of a tradeoff between efficiency and quality in service production processes. Therefore, this thesis aims to explore if the tradeoff in a production setting with low variability in demand and low customer participation exists, after Lean has been implemented. With a qualitative approach, a case study has been conducted at Scandinavian Airlines Ground Handling to evaluate the effects of Lean in the baggage handling process. The result of the study shows that the tradeoff has not been overcome; efficiency has increased at the expense of quality.
Honung och biodling : honungens ursprung, egenskaper och effekter på människans hälsa
This report describes honey, its origin, properties and effects on human health. Honey has been used for a long time in most civilizations and apiculture is an important activity sector in many parts of the world. The trend is an increase in honey production but a decrease in the number of beekeepers in Sweden. Honeybees live in a highly developed society with a strong hierarchy and a well organized distribution of the tasks. They visit a broad spectrum of plants and collect nectar to store it as honey.
Urmakarens budbärare : Modern intelligent design-rörelse i jämförelse med brittisk naturteologi vid 1800-talets början
I uppsatsen jämförs William Paleys Natural Theology : or, evidence of the Existence and Attributes of the Deity, collected from the appearances of nature från 1802 med Michale J. Behes Darwin's black box : The biochemical challenge to evolution från 1996. Jämförelsen kontextualiseras med en skiss över evolutionsteorimotståndets historia under den mellanliggande perioden, som tillsammans med själva den vetenskapliga utvecklingen, antas förklara de skillnader i tilltal och val av argument som föreligger mellan de två verken. I fråga om grundläggande budskap, idéstruktur, syfte och religiositet befinns de två verken ligga varandra betydligt närmare än vad som initialt kan tyckas vara fallet..
Vem styr mitt arbete? Förändrade arbetsuppgifter vid datorisering av körschema
Abstract This report is our bachelor thesis. Our work has taken place at a galvanising company in Sölvesborg. The company faced major changes, of which one was a computerisation process. The new system could involve changes in work practice and in specific tasks, affecting the workers. If the coming system was to support work, from the production personnel?s perspective, we felt a legitimate participation in the development and design of the future work practice, was a requirement that was not met.
Mittens Rike : etableringsmöjligheter och framtidstrender
China has the world?s largest population and during the last thirty years the country has implemented political and economical changes that have affected China to move towards a more western market economic direction. At first this development was going slow but during the last five years it has increased which today has made China the world?s greatest growing economy. China?s improved cooperation with the world is one reason for this growth which has led to a cumulative of the consumer market.
