Kvalitetsprocesser och mätning av pinnfräsar : ? Empirisk studie av produktionsmätutrustning vid frästillverkning

This master thesis investigates quality procedures and measuring of solid carbide end mills, with the main focus on measuring equipment. The thesis has been written in collaboration with a special production department for solid carbide end mills at Sandvik Coromant in Gimo. The department?s needs and constraints have been the foundation of the project and the main research question is: how to measure end mills in order to ensure good quality of the produced end mills. The project has contained both a theoretical study consisting of a literature review and practical studies in the workshop with the objective to identify an end mill?s main parameters and the relationship between an end mill?s geometry and the manufacturing processes.

Grön elproduktion i Sverige: en studie av faktorer som
påverkar valet av grön el

Syftet med uppsatsen är att med hjälp av en binär modell klargöra vad det är som styr att en del svenskar väljer att köpa grön energi, genom att ta reda på vilka faktorer som påverkar sannolikheten att en genomsnittlig individ väljer att köpa ?grön el?. Samt att se hur framtidens intresse är för grön el. Ett delsyfte med uppsatsen är att göra en jämförelse mellan Sundquists doktorsavhandling från 2002 och Temo ABs undersökning från 1998 för att se om kunskapen och attityderna kring grön el har förändrats. Temos studie var en klartläggning av svenskarnas kunskaper om beteende och attityder kring grön el, studien gjordes för Sveriges elleverantörer.

Spelmarknadens utveckling och relation till spelproblemen i Sverige 1999-2009 med fokus på män i åldern 18-24 år

The share of problem gamblers increased for men between 18-24 years old during the period 1999-2009, while the share were steady or decreased for other classes of population. This study examines the relation between this development of problem gambling and the Swedish gambling market. The factors that are studied are the functioning of the market with a focus on the new Internet market for gambling, the games and the underlying risk factors in those, the marketing and other factors outside the gambling market. First a large literature review was made to map the development as detailed as possible. After that a qualitative analysis of the content in television commercials was done to see if they were made for the problem group.

Analys av sorptiv kylning i industri- och kontorsbyggnader

Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness.Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat.

Rättfärdighetsbegreppet i Matteusevangeliet Språkliga betydelser och teologiska funktioner av 'rättfärdighet' och 'rättfärdig'

This thesis examines the concept of righteousness in the Gospel of Matthew. The research explores the literal meanings and theological functions of the noun ?righteousness? and the adjective ?righteous? through a descriptiveand comparative study of all the pericopes which include these words. The research also includes relevant information about the historical context of the text as well as the central theological themes which relate to the subject.In the research on the literal meanings, it seems that both words primarily occur in ethical teaching and that the concept of righteousness in Matthew is closely related to humanconduct (e.g. Matt 5:20; 6:1).

Utveckling av högspänningskontakt

This report describes the development of a high-voltage connector at the request of Scandinova Systems AB in Uppsala. The development process is described from the making of a customer demand specification, to the making of drawings for the manufacturing of prototypes. Scandinova develops high-voltage modulators, hence the need for connectors that can handle very large power pulses. Their current connector has several weaknesses that may cause the connector to melt or catch fire. The development began with a number of studies that included the modulator structure and the current connector structure and functions.

Social media & marknadsföring

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Klimatfrågan -från en kritisk händelse till en politisk modefråga?

Few issues have been exposed in media recently as much as the climate change issue. Afterthe documentary film ?An Inconvenient Thruth? presented by Al Gore was released in 2006,most of the world saw a lot of attention directed towards global warming. This was a turningpoint that is refered to in this dissertation an history-graded critical event, which is assumed tohave a significant impact on peoples lives.The purpose of this dissertation is to examine whether or not political parties in Swedenresponded to this critical event in the way that they, in their party programmes, haveformulated policies related to climate change. Alternatively if media produces an image ofpolitical activity which does not comport with the forming of actual political standpoints.

Evaluation of indirect blood pressure measurement, plasma endothelin-1 and serum cortisol in clinically healthy horses

Equine metabolic syndrome (EMS) it?s a clinical condition that includes obesity, regional adiposity, insulin resistance (IR) and laminitis. A similar syndrome exists in human medi-cine, the metabolic syndrome (MS), were systemic hypertension also is a prominent fea-ture. The systemic hypertension seen in humans with MS is partly due to a vascular endo-thelial dysfunction with an enhanced endothelin-1 (ET-1) mediated vasoconstriction. There are indications that systemic hypertension might be a feature in EMS as well but if ET-1 is involved in the development of the systemic hypertension in horses is not known.

Demand and perception of fertilizer : among small-holder farmers in Kenya

Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.

Stockholms skärgård - ett landmärke för Stockholm : En studie om huruvida Stockholms skärgård har potential att fungera som en primär attraktion för Stockholm

There is a growing trend in the world, where cities compete with each other by building similar attraction to enhance the tourism at the destination. This competition often results in the opposite where the cities lose their authenticity. Stockholm on the other hand does have the possibility to offer its visitors Stockholm?s archipelago, which is a unique natural phenomenon that cannot be replicated. Stockholm is the most popular tourist destination in Sweden.

Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier

This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.

Köpcentrumsteori : Fallet Galleria Duvan

The demand for shopping centers has increased in recent time and more shopping centers have been built. To become competitive shopping centers has evolved to become more than just a place for shopping. In the recent past Galleria Duvan in Karlstad has been run by foreign owners who has not been involved or renovated the shopping center. During the spring of 2011 AlbérFastigheter bought Galleria Duvan and they are now renovating and negotiating new deals with the tenants. Our problem has led us to the following question: How can a centrally located shopping center, such as Galleria Duvan, develop a strategy to strengthen their position on the market.

Solmodul jord- och bergvärmepump

An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.
