Robotstudio för bearbetning

Projektet ProFlexA syftar till att automatisera gjutgodsrensning av stålgjutgods vid lågavolymer genom att använda ny adaptiv teknik såsom flexibla fixturer och gripdon samtkraftstyrning. Projektet bedrivs av Linköpings Tekniska Högskola och Lunds TekniskaHögskola med stöd av tre gjuterier i Mellansverige samt systemintegratörer och leverantörer.Automatisering av gjutgodsresning har länge varit föremål för både forskning ochkommersiellt intresse. Det finns idag fungerande lösningar främst riktat mot aluminiumgodsoch högre produktvolymer.Syftet med examensarbetet var att undersöka huruvida Robotstudio, och mer specifikt desstilläggsmodul Machining, var lämpligt för användning vid gjutgodsrensing. För att detta skallvara möjligt på hårdare material krävs kraftstyrning, vilket finns som tillval i den tidigarenämnda tilläggsmodulen.För att ha möjlighet att testa machiningmodulen och få en uppfattning om vad Robotstudio ärkapabelt till genomfördes först en självstudie av programmet. Som delmål för instuderingengenererades en visuell robotcell enligt ett av ProFlexA:s tidigare koncept förgjutgodsrensning.

Logistiska lösningar för en lönsam byggprocess

This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.

Gör dina egna kartor : undersökning om kartan som metod och kunskapsbyggare

På vilka sätt kan kartor hjälpa oss i dagens samhälle? De flesta av oss har tillgång till en karta med GPS när som helst, i våra telefoner. Behöver vi kartan i vårt dagliga liv på andra sätt än genom denna (ganska) exakta positionering? Det är några av frågorna som ställs i detta examensarbete, där kartan undersöks som metod och byggare av kunskap. I detta arbete har mitt intresse för kartor slagits samman med ett hantverksnära arbetssätt.

Solar energy on Swedish pig farms : a sunny story?

In Sweden there is a large interest in renewable energy but the market for solar power is still small compared to other countries such as Germany. Here many farmers produce their own electricity. The Federation of Swedish farmers have acknowledged the potential for Swedish farmer to produce electricity and there is an interest among the farmers. The agricultural branches in Sweden most suitable for solar power are pig production and poultry due to the even electricity need throughout a year. Swedish pig farmers are going through a period of unsteady profitability which makes it interesting to see whether producing their own electricity can affect the economic situation.

OMSTÄLLNINGSBEREDSKAP - En kartläggning av omställningsberedskap i kommunala förvaltningar i Västra Götalandsregionen

The study focuses on mapping how well prepared the counties in the west region of Sweden is in case of restructuring. The study explores what kind of activities and routines that contributes to prepare the organization for restructuring. The study also aims to investigate the effect of precedent restructuring, and if the counties who experienced restructuring are more prepared than others.The research within the field of restructuring characterizes of an evaluating nature and the focus has been after the restructuring occurred. There have also been a lot of studies of the negative consequences on individual and organizational level. Since downsizing is a frequently used method by management despite its consequences is it important to investigate how organizations can learn and thereby be more prepared for restructuring.

Vad är ?rätt? gjutkvalitet? Hur uppnås det?

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

Läsflyt : En interventionsstudie på två läsmetoders effekter på läsförmågan.

Sammanfattning Syfte: Att undersöka två läsmetoders effekter på tolv elever från skolår 2, 3 och 4 avseende fonologisk och ortografisk läsförmåga, läsflyt, läsförståelse och RAN (Rapid Automatic Naming) samt jämföra resultaten med en grupp elever som fått traditionell specialundervisning under samma tid. Metod: 52 elever genomförde en screening med avseende att mäta läsflyt och läsförståelse. Av dessa valdes 12 elever ut som hade svårigheter i läsflyt och korrekt läsning, fyra elever från varje skolår, 5 pojkar och 7 flickor. Eleverna delades i två lika stora grupper som tränade ordavkodning med två olika metoder i en-en-undervisning, 20 minuter tre gånger per vecka i sex veckor. De 18 eleverna fick utföra ytterligare fem läs- och skrivtest före och efter interventionen. Resultat: De båda interventionsgrupperna förbättrade sina resultat på flera test mer än gruppen som fick traditionell specialundervisning. Elever som tränat Rydaholmsmetoden fick bättre resultat i alla högläsningstest utom ett.

Hantering av småskalig elproduktion : Utveckling av modell för dokumentation och elkvalitetsberäkningar

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

Om vägen till ett bättre bestånd vid ett skolbibliotek ? en aktionsforskningsansats.

For a school library to function as a support for the students? development of their academic abilities, it must provide material satisfying their needs as well as the needs of the teachers. The school library should assist the students in their research endeavours, as well as inspire reading for pleasure. In order to do this it is imperative that the school library actively develops the existing collection and continually strives to meet the needs of its users. The aim of this Master?s thesis is to describe and reflect upon how a particular school library works with collection development.

Energikartläggning hos RostiGP i Gislaved

In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

Ekonomisk styrning i banksektorn : En jämförelse av två storbanker i Sverige med fokus på flexibla styrmedel.

A more complex and turbulent world market puts pressure on flexibility and the ability to adjust its business to the market changes. The rapid and unpredictable change is hade to analyze and forecast which demands more short-term forecasting. The issue for this dissertation is based upon the demand of more flexible ways of doing business in the bank sector in Sweden, which is a turbulent and unpredictable market. Handelsbanken is a company that uses the so called Beyond budgeting concept and the dissertation is about this company?s ability to solve the economic governance without the traditional budgeting process.

Som man betalar f?r man banta. En kvalitativ analys av hur traditionella nyhetsmedier gestaltar Ozempic

In the past year, Ozempic has been observed internationally, as well as in the Swedish press, due to its rapid rise in popularity, its off-label use for weight loss, and the ethical and societal debates surrounding availability and impact. The purpose of this study is to examine how Ozempic is portrayed in the four largest Swedish daily newspapers: Svenska Dagbladet, Dagens Nyheter, Expressen and Aftonbladet. The aim of the thesis is to identify the frames within which the drug is described to acquire knowledge of how it influences public perception of it. Every article published between the first of March until the first of November has been included in the study, if it bottoms in the defined phonomenon. The method used is a qualitative text analysis in consideration of Entman?s framing theory, which is focusing on identifying dominant themes, problem definitions, proposed solutions, and the actors attributed responsibility in the coverage of Ozempic in Swedish press.

Varbergs besökscentrum - Nybyggnation

This report deals with activities that from a CSR perspective are considered to create a shared value for a medium-sized construction company in Sweden. The CSR definition used in the report is the European Commission?s since it reflects the valuecreating aspects of CSR, in contrast to the traditional philanthropic aspect of CSR.Companies in the building construction industry have difficulties identifying activities that create value in society and in the company. The aim with the project is to, from a CSR perspective, identify and evaluate value creating activities in a building construction company. The activities will be evaluated with respect to competitiveness and how they can be implemented into an organization.

Funktionella krav på metadata: En undersökning av Dublin Cores överensstämmelse med FRBR

The purpose of this master thesis is to examine how Dublin Core corresponds to the findings in the IFLA report Functional requirements for bibliographic records FRBR, and what consequences this correspondence has on the usability of Dublin Core as a bibliographic standard. While the study describes the conceptual model of FRBR and the entities work, expression, manifestation and item, its main focus is the mapping of attributes and relationships to the user tasks defined, namely to find, identify, select and obtain entities. The study makes a comparison between data that FRBR rates as highly important for any user task, and the elements defined in DCMI Metadata Terms. The outcome of the comparison is then analyzed as to how it affects Dublin Core's possibilities to assist in the different user tasks, and common problems are discussed. The results show that problems in expressing attributes and relationships through Dublin Core elements concern all of the four user tasks.
