Ecolean Development AB are developing and manufacturing filling machines for pasteurized liquid food products. Because of lack of any appropriate supplier of box closer which seals boxes with small flaps, they have decided to start a project to develop a prototype of a box closer. Due to long experience from industrial automation I have been given a chance to develop control system for a box closer. Degree thesis involves electric design in ELPROCAD ic PRO and programming of PLC (programmable logic controller) and HMI (Human Machine Interface). The report describes degree project from the project plan phase via the development phase to the conclusions.

Denna rapport beskriver examensarbetet vi gjort för LBS Science Park AB. Anledningen till att vi gjort just denna applikation var att LBS Science Park såg ett problem i den Internetbaserade hästannonsmarknaden. Det fanns ingen ledande annonssida, utan användare som skulle sälja eller köpa hästar fick använda sig av flera mindre sidor. Vår uppgift blev att undersöka marknaden och att skapa en applikation som samlar annonser från flera hemsidor på vår applikation. Rapporten är indelad i tre huvuddelar, som belyser de juridiska, de tekniska och de innehållsmässiga frågorna.

The aim of this study is to illuminate social worker?s perception of social class within the Swedish social service system. This study therefor examine if social class contributes to the production and reproduction of the client and what impact social class has on the interaction between client and social workers. The study was conducted with qualitative semi-structured interviews with social workers from three different departments of social service. The theoretical approach is Yeheskel Hasenfeld?s theory about moral practices in welfare organisations, Michael Lipsky and Roine Johansson?s theories about client construction and Pierre Bourdieu?s class theory.

AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.

In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.

Purpose: To compare the expectations of coming profession in social work with experienced social work. We wanted to compare the pictures between the students in school of social work studies with social workers. We also wanted to increase social workers as well as other readers? awareness of social work as a profession.Questions: What characterizes the school of social studies? How do students in school of social work view the coming role as a professional? How do students in school of social work view upon social workers as professionals? How do social workers view upon their own profession? How do social workers view upon the own role as a professional? How do social workers view upon the relation between the idea of the profession and the daily practice? How do the students in school of social work studies and social workers view upon professional social work?Method: Qualitative study with qualitative interviews.Conclusion: Social work is a low status profession. How to increase the status of social work is not easy.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

I programmeringsvärlden har en ren, enkel och testbar kod en stor betydelse. Detta examensarbete avslöjar ett nytt koncept vilket kanske är den viktigaste upptäckten inom metodområdet på senare tid, så kallade Testdriven utveckling (TDD). Testdriven utveckling är ett sätt att utveckla mjukvara och det som utmärker den är att man först skriver ett test som inte ska fungera (röd fas), sedan skriver man en kod, så enkelt som möjligt, som gör att testet ska fungera (grön fas) och till slut ska man våga göra förändringar även om koden fungerar, om man är inte riktigt nöjd eller om man helt enkelt vill optimera sin kod (omstrukturera fas). Syftet med studien var att utvärdera vilka fördelarna och eventuella nackdelarna är med den här typen av mjukvaruutveckling, att motivera varför det är lämpligt att välja den och att visa hur man gör med hjälp av Java, JUnit och Eclipse. Material som användes i studien insamlades genom litteratursökningen och intervjuer.

This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.

Syftet med denna studie är att ta reda på hur medvetna gymnasieelever är om it-säkerhetshot och risker på Internet. Detta har gjorts genom att först undersöka aktuella hot genom att studera trendrapporter från ledande it-säkerhetsföretag. Denna information har sedan använts i en enkät för att ta reda på kunskapen och medvetenhetsnivån om dessa it-säkerhetshot bland gymnasieelever i Uppsala. Studien visar att det finns ett behov av utökad kunskap inom området. I resultatet kunde särskilda brister ses i de sociala aspekterna av it-säkerhet.

My big interest in sports was what shaped my choice of subject for the essay. The purpose of this study has been to explore the social meaning of team sports for functionally impaired persons. In order to fulfil the purpose of the essay I formed following questions: How do the actives experience their participation in team sports? And how important is the social intercourse in team sports to the individual welfare? The methods I?ve used have been qualitative with an ethnographic approach. I have used participant observations and field interviews to gather my empirical material.

AbstractThe purpose of this study was to identify problems that may occur in the execution of a civil engineering project and suggest measures to reduce the risk of errors. The study was conducted in cooperation with a civil engineering company in the Gothenburg area. During two weeks in February 2012, a field study took place on two construction sites where disruption and problems that took more than 15 minutes to correct were noted. During the field study we identified 39 such occurrences in the projects and then these were classified into different categories according to their cause.The two largest categories were "Design" and "Planning", which accounted for half of the errors that were discovered.In the study results were evaluated to decide whether it was possible to detect discrepancies at an earlier stage. The cost to fix an error in the design stage may be significantly less than to correct the problem in production.According to the evaluation, 55% of the errors could have been detected earlier if there was a greater degree of observation for such issues by everyone involved in the project.

This study analyses social age as a phenomenon and if unaccompanied refugee children has a social age that, according to the Swedish culture, do not correspond with their biological age and if so is, the reason for that. Furthermore, our study has discussed the potential consequences of the effects for the unaccompanied refugee children and the social age when interacting with Swedish society. According to our study, the social age is effected by other factors besides cultural norms, values and role expectations that a society has on a specific biological age. The results in this study shows that social age is a vital component to someone?s identity.

The theme in this report has been how to benefit experience from accident investigations. The demand on the municipality to perform accidet investigations is relatively new, and maybe they aren?t clear what the demands means. This causes that there might be a problem to benefit experience from accident investigations, for improving the overall safety in the municipality. The main purpose of this report has been to clarify how experience from accident investigations, can be of benefit to society on a local level.

Social phobia is a fear which limits a person's capabilities in daily situations. The fear can be so strong that a person can distance themselves from all social situations, for example education, marriage, sports activities etc. The purpose of this study is to discover whether there are any correlations between social fear and choice of educational program, between social fear and sex, and between social fear and Internet use. Questionnaires were administered to 80 upper secondary pupils. Each questionnaire answer was assigned a certain score, which was then coded in SPSS, the highest scores corresponding to highest degrees of shyness.
