The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

The interest for locally produced food is increasing due to consumer concern about the environment, distrust of industrial foods and a demand for high quality products. Apple is the predominant fruit crop in Sweden, and by processing apples into cider and vinegar, these products could significantly contribute to the development of the market of local foods.In this study different yeast types and different bacterial cultures were evaluated for their suitability in cider and vinegar production from cloudy apple juice. Ten apple cultivars (Aroma, Baldwin, Belle de Boskoop, Bramley, Cortland, Gravensteiner, Ingrid-Marie, Jonathan, Rubinola and Spartan) were also evaluated for their suitability for production of juice, cider and vinegar. Chemical analyses including total soluble solids, titratable acidity and total phenols were performed on the products along with sensorial evaluation by taste panels.The yeast strains were shown to have an effect on fermentation rate and the resulting content of total phenols in ciders fermented from cloudy apple juice. Dry commercial starter strains gave a higher appreciated cider compared to cider that was spontaneously fermented, and the ale yeast Safale S-04 was concluded to be the most suited for fermentation of cloudy apple juice.For vinegar production, the bacterial culture had an effect on TSS, but not on any other chemical or taste characteristics.

To increase the understanding of how individuals total life situation affects their stress level and health has lately more frequently been discussed in different contexts. Furthermore, it is important to have knowledge of power structures that exist under given circumstances in a society to get an increased understanding of how to structure the health promoting work to get the highest possible benefits. People?s work life is essential to their health, since we spend a lot of time at work. The aim of this study was to find out which factors that relate to nursing staff?s health and stress level from a general perspective.

Arbetet visar praktiskt hur en organisation kan utnyttja kvalitetsbristkostnader, för att sedan utifrån dessa identifiera möjligheter till förbättring. I arbetet används identifierade kvalitetsbristkostnader för att ta fram en projektplan för motortillverkningen. Projektets resultat ska medföra att kvalitetsbristkostnaderna vid motortillverkningen minskas. Arbetet börjar med att identifiera vilka kvalitetsbristkostnader som motortillverkningen har dokumenterat. Därefter tas en enkät med öppna frågor fram, vilken behandlar kvalitetsbrister vid motortillverkningen.

The theoretical background in this essay made clear that the students? knowledge about physics improve, and they express a more positive attitude towards physics as a subject, when they have access to a more laboratory-based learning style. The aim of this study is to research how the placement of the lab relative to the lecture affects the students? experiences and level of knowledge. The study involved students in year eight and was carried out during four weeks.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Executive SummaryThis final thesis has examined the effects of an increased centralization and better coord­in­ation of the distribution logistics at ABB in Västerås. The company is today strongly decent­ralized and there is a minimum of collaboration between the 20 business units. This is why the questions were raised; how could the business units coordinate outbound logistic activities and what effects would that provide. The obj­ect­ive of this final thesis is to provide basic data for a future decision-making which desc­r­ibe these effects.The report has mapped out the factors that are important to ABB in an evaluation of their logistic activities and how the outbound logistics work today. The four factors are cost efficiency, delivery service, environmental impact and logistics capability.

The cost of forwarding corresponds to about one tenth of the forestry industries raw material cost. This gives a motive to do good follow-ups to get a good overview of the forwarding distance and, thus, enable improvements. Follow-ups are also justified by the possibility to make more accurate calculations of the harvesting costs, if better estimations of forwarding distance are achieved. Today (2009) Stora Enso has GPS and vehicle-computers in most of their forwarders. These are used mainly for the forwarder to follow the tracks of the harvester and for the planning leader to see how the forwarder has been driving within the stand.

Dagkirurgi verksamheten ökar och det pågår en debatt om vilken anestesiform som är mest lämpad för denna verksamhet. Snabb återhämtning, god kvalitet, kostnadseffektivitet och få biverkningar är målen för att få patienten att kunna gå hem samma dag. En kvantitativ studie med en enkät framkonstruerad för studiens syfte utfördes. Syftet med studien var att undersöka vad om avgör om en patient skrivs ut tidigt eller sent vid dagkirurgi med övningsmetod intravenös anestesi Target Controlled Infusion TCI eller Total Intraveös Anestesi TIVA. 20 stycken patienter på en dagkirurgisk avdelning observerades postoperativt av ansvarig sjuksköterska, som fyllde i frågorna i enkäten.

This Master thesis was written for Lantmännen Agroetanol in Norrköping concerning the layout of their finished goods inventory and unloading of feed after introducing a new product mix. Lantmännen Agroetanol has two production lines which produces feed. Both lines lead to six silos, used as inventory of finished goods. The feed from the two production lines differ in terms of quality, where as Lantmännen Agroetanol wants to separate their finished inventory in order to charge a higher price, by selling the better product as a premium. With two different feed products the yearly revenue is expected to increase which motivates a research about the current capabilities and necessary changes to be made in the factory.

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

AimThe purpose of this study is to analyze factors that affect the price on tenant-owner apartments in the central parts of Uppsala. Special attention is put on analyzing how the monthly fee and the location affect the price. The hypotheses are that the monthly fee and the distance to the central part of the city have a negative effect on the price. A number of additional price affecting factors was taken in consideration during this study.MethodThis study is mainly based on data supplied to us by Mäklarstatistik. The supplied data consists of information about tenant-owner apartment sales in Uppsala during a year under 2008 and 2009.
