Fejans vandrarhem ? En studie om isolering och uppvärmningsalternativ
During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.
Att reducera ledtiden i en produktion med hög variation och låg volym - En casestudie på Lab.gruppen
Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.
Vinterträdgårdar ur ett byggperspektiv : En undersökning om byggandet av vinterträdgårdar
The purpose of this of this essay is to explore the construction of a conservatory that is livable allyear around. When you build a conservatory there are several factors that need to be regardedthat usually are of no importance when you build a regular conservatory. The glassed facadeneeds to have a very good U-value and all the parts of the facade need to be isolated and theconstruction needs to prevent thermal bridges.In this essay we will start by looking at the shape of the conservatory. Due to the façade consistsof glass the conservatory will need to have a good ratio between the area and the façade so thatthe heat losses will be at a minimum. However, due to the fact that one of the sides of the façadeis connected to the warm house, you quickly realize that the shape of the conservatory is of noimportance.There are two common ways to build a foundation for a conservatory, a molded concretefoundation and isolated wooden beams.
Vem får ansöka? : En kvantitativ vinjettstudie om biståndshandläggares benägenhet att ta emot ansökan från anhöriga.
This essay is about needs assessors within public elder care. The method is a quantitative vignette study. The aim of the study is to find out whether there is an existing consensus among the needs assessors when a relative to a client with reduced cognitive functions wants to make an application even though the client does not want to. We also wanted to find out whether there are any underlying circumstances which have influence on the needs assessors? reactions to this specific situation.
Påverkande faktorer för grotens fukthalt
The aim of this study was to investigate how seasonal variations affect the quality of logging residues. The study was hosted by VIDA Energy.
Logging residues can be processed and transported within different systems. Today the dominant systems are chipping at landing and bulk transportation of logging residues. In these systems the handling of the logging residues are carried out in the same manner up to the landings.
Moisture content at the time of chipping is the primary quality parameter. Fine fractions of logging residues are strongly dependent on moisture content in storage.
Det lutar mot Lean : En jämförelse av arbetet med- och effekterna av arbetet med Lean på ASSA AB med teoretiska kunskaper inom ämnesområdet.
Sammanfattning Datum: 2011-01-14 Kurs: Kandidatuppsats i företagsekonomi Lärosäte: Mälardalens högskola Akademi: Akademin för hållbar samhälls- och teknikutveckling Handledare: Lennart Bogg Examinator: Cecilia Lindh Författare: Wilhelm Moby och Pia Robson Nyckelord: Lean Production, implementering, effekter. Titel: Det lutar mot Lean ? en jämförelse av arbetet med- och effekterna av Lean Production på ASSA AB med teoretiska kunskaper inom ämnesområdet. Problemfrågor: Hur har ASSA AB gått tillväga för att införa Lean Production och vilka faktorer har varit avgörande?Vilka effekter har införandet av Lean Production givit verksamheten? Syfte: Den här studien ämnar undersöka och sedan jämföra arbetet med- och effekterna av Lean Production hos ASSA AB med teoretiska kunskaper inom ämnesområdet. Metod: Metoden är av kvalitativ karaktär och med hjälp av djupare litteraturstudier och en semi-strukturerad intervju ska studiens syfte uppfyllas. Slutsatser: Resultatet av den här studien kan sammanfattas med att det som framkommit i den empiriska undersökningen mycket väl överrensstämmer med det som sägs i den teoretiska referensramen. ASSA AB har först infört verktygen 5S och standardiserat arbetssätt, vilket möjliggjort införandet av andra verktyg såsom kanban. Inget av detta hade dock varit möjligt med ett lyckat resultat om inte personalen först blivit utbildade och en leankultur skapats.
Separator: Aktionsforskning i en dansproduktion där ledarskap undersöks samtidigt som en ny organisationsform introduceras
There is a common belief that the arts contain knowledge of creativity that can enrich the business world. Similarly, the arts are in need of additional support from the private sector and know-how of business practices. In short, there is a need for mutual understanding. With my background as a dancer paired with my studies at the Stockholm School of Economics I have taken the challenge of bringing the two worlds closer together. By changing a social system, like an organization, it is possible to get a better understanding of it.
Go East!: En fallstudie av lokaliseringsbeslutet vid offshoring
This paper aims to determine what is decisive for localisation of production units when a company engages in offshoring. By performing a case study on Electrolux and comparing the results with theoretical literature we discuss the implications for manufacturing companies in general. To facilitate a structured analysis we have developed a model dividing the localisation decision into five perspectives and four geographical levels. We have found that the determinants of localisation vary depending on the geographical level of the decision process. Since all geographical levels are interconnected, the analysis needed for a decision on all levels simultaneously is very comprehensive.
Medborgardialog i Rasbobygden : En fallstudie i Uppsala kommun
ABSTRACTCitizendialogue in the District of RasboA Case Study in the Municipality of UppsalaAuthor: Camilla ÖstlundSupervisor: Stig MontinThe essay is written inside the scope of Örebro Universitys evaluation of the new organisation in the municipality of Uppsala.The purpose of this essay is to study the citizendialogue in the district of Rasbo. This will be done partly by an examination of how the participants themselvesperceive citizendialogue. Their descriptions are put in relation to deliberative democracy and its critics amongst other. Partly by study how those involved have choosen to put it into practice. The opponents of the reorganization chose to start a non-profit association, Rasbo in co-operation, to carry on local mobilization and it will be compared with other similar groups.
Flödesanalys av plåtsammansättning : Strävan mot Just-In-Time och minskat slöseri
The Volvo Trucks plant in Umeå is a highy complex manufacturing facility where the same production line handles a variety of different models. This require flexible and agile processes with high quality standards. This thesis studies the flow of material through a production line and how Volvo can use their existing manufacturing monitoring system to optimize the flow of materials.The goal with the thesis is to identify eventual problems with the flow of materials and to deliver a few proposals on how the production line can improve its productivity. The theory of LEAN, Just-In-Time and Supply Chain Management serves as the scientific reference to this project. By analyzing the flow of material, performing interviews and observing the processes a few problems are identified.
Korrektion och imitation som mätverktyg för diagnos av PT-nivå : Kan man korrigera eller imitera en grammatisk struktur som man inte kan producera i fri skriftlig produktion?
The purpose of this study was to examine whether a L2 learner could correct or imitate structures of the language that they could not produce in written production defined by processability theori levels.The Informants had Arabic as their mother tongue. The study showed that the ability of correction developed slower than the capacity for imitation and the ability to written production. The ability of the correction developed by the duration of the stay. The result was a confirmation of theory formation in processability theory. Corrective elicitering could be developed into a useful diagnostic tool in the classroom and thus provide an education that followed a natural learning order according to processability theory by Pienemann.Keywords: processability theori, imitation, correction, written production.
Optimering av OTEC-system
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.
Jämförelseförsök mellan ogräsharvning och radhackning :
The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010.
The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing.
In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment.
The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment.
Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..
