This report deals with RFID systems and how to detect nearby tags with the Mifare standard using only a microcontroller and an antenna circuit.The aim was to investigate whether there was any possibility to continuously search for a nearby tag for a system operated with batteries without compromising   the lifespan of the battery. At this time the system would take too long time to wake up and look for a tag to give a satisfactory battery lifespan, which should be done a couple of times every second.The report has two issues, namely:Is it possible to direct the microprocessor to detect and identify a nearby tag after the Mifare standard?What hardware is required for this to be possible?As the research method to provide answers to the above questions an action research was used. This approach has meant that the group worked on information retrieval, examined existing solutions, tested their own solutions and documented the results.The group examined an existing solution that can search for nearby tags with minimal energy consumption. An antenna circuit was built that was connected to the processor.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

Design for Six Sigma (DFSS) is a further development of the Six Sigma draft to carry through preventing quality measures in developing and designing of new products and processes. With increasing demands on enterprises development processes to be more safety and faster the need of DFSS arise as a product, process and service development concept in the organisations. Design for Six Sigma aims to improve and structure the development process of an organisation and consider the application of the innovation problem solving. The concept aims to leave the structure of the traditional Six Sigma concept and instead, from an innovative perspective, search for new solutions to existing problems. The concept constitute of a toolbox with a lot of quality tools that are divided into phases in a development model.

A flat organisation makes a horizontal career development possible, which means that it is more important to develop an individual?s knowledge base than to gain a higher title. This leads to a personal development, which motivates expats to stay. Since the responsibility of the career development mostly lies on expats themselves, companies should create conditions that make individual, internal job search possible. Like in IKEA:s case, it can be done through a strong and prestige less company culture, that penetrates the whole company.

Köpingsföretaget GETRAG All Wheel Drive AB utvecklar, tillverkar och levererar komponenter för drivteknik till personbilsindustrin. Genom projektet 580-9 planerar företaget att införa en monteringsbana för en nyutvecklad produkt. Till denna önskar företaget skapa en materialhantering som är kostnadseffektiv, lever upp till kundernas krav på hög kvalitet samt utesluter hantering av träemballage vid monteringsbanan. Syftet med examensarbetet är därför att ge förslag till en kostnadseffektiv materialhantering där emballage som avger restprodukter inte hanteras vid monteringsbanan.För att undersöka examensarbetets frågeställningar har vi utrett hur materialförsörjningen till banan bör skötas. Studien bygger främst på teorier om lean produktion och förpackningslogistik.

According to the Swedish preschool policy documents all children should have the same opportunities to develop their early language skills regardless of their social background. The purpose of this study is to investigate how preschool teachers work with children's early literacy and language development with focus on reading aloud. The reason is to investigate how the preschool teachers work to create an environment that stimulates children's literacy and language development. Another intention is to study how often reading aloud occurs in the children's home environment and what the preschool teachers thoughts are about that. The study is based on interviews with four preschool teachers and surveys that were answered by parents.

Vi har genomfört en kvalitativ studie på en lagerverksamhet som till stor del använder sig av bemanningsföretag för att möta marknadens behov av olika toppar och dalar. Företaget som vi har gjort vår studie på vågar gå mot strömmen och satsa på sin verksamhet, då de har genomfört en stor omorganisation, jämfört med många andra företag på dagens marknad.Vi har genomfört intervjuer på sex personer som är anställda av företaget och som jobbar som lageranställda, dessutom har vi genomfört två intervjuer med personer som jobbar högre upp i hierarkin och som är anställda via bemanningsföretag. Till en början hade vi ett deduktivt förhållningssätt baserad på Lean Production. Men då empirin gav oss intressanta infallsviklar lät vi denna styra vår studie vilket innebar att vi fick andra teoretiska utgångspunkter och dessutom en blandning av deduktiv och induktivt förhållningssätt. Bland annat valde vi Foucaults teori kring övervakning som huvudfokus i vår studie då det var kring detta ämne vi fick fram intressant empiri.

The purpose of my study is to investigate teacher?s perceptions of their mission in the preschool class, and how they work to promote children?s written language development. What methods and working methods they use to awaken curiosity and motivate children to read and write. I am using the qualitative research method to get answers to my questions. I have made four qualitative interviews with four teachers in preschool classes from different schools.My questions are:What conceptions does teachers have about their mission in a preschool class?What different methods and approaches does teachers use to stimulate and wake children?s curiosity for reading and writing development?The theoretical basis for my study is the socio-cultural perspective, where learning occurs in interaction.

Personal trainer is a profession that has grown strongly in recent decades, and has become increasingly common in the labor market within the health sector due to the widespread and growing interest in health and self- improvement. Further more, personal training is a great example of occupations with a close interaction between producer and consumer. The purpose of this study was to examine whether and if so how, personal trainers experience that the relationship with the clients affects their own personal development. This by finding out what impact the profession has had on the personality, what impact the relationship with the clients has affected the leadership, and last what impact the relationship with the clients have had on the personality based on social and mental aspects. Based on the purpose of the study qualitative method was chosen and data was collected with qualitative interviews.

The goal of this work has been to create a flexible strategic group-based artificial intelligence for the Arrowhead Game Studios-game Magicka, by implementing, using and examining different AI-techniques that's used in many commercial games in more or less extent. C# is the programming language that has been used in the development, and the implementation has been made as flexible as possible to make further development and extending AI-rules etc. easier..

Examensarbetet har genomförts på den produktionstekniska avdelningen på Volvo Construction Equipment i Hallsberg.Syftet varatt ta fram ett nytt koncept för hyttsvetsproduktionen på fabriken;hur produktionsprocessen skulle kunna se ut i framtiden. Man vill göra flödet i linan mer effektivt med avseende på kvalitet, flexibilitet samt eliminera tidsslöseri som idag är ett problem.När fabriken påbörjade sin produktionproducerade man två olika varianter av hyttertill anläggningsmaskiner, idag har man ökat produktionen till fyra varianter. I takt med att varianter samt orderingång ökat har man byggt på befintlig produktionslina istället för att utveckla en ny, anpassadlinafördet nya läget. Resultatet har blivit att maxkapaciteten är nådd och linan klarar inte att hantera en planerad produktionsökning.En grundlig analys av hyttsvetsprocessen, innehållande intervjuer med bland andra platschef, teknisk chef och flera tekniker genfördes för att få förståelse för processen. Övrig information såsom effektivitetsmätningar på utrustning, värdeflödesanalyser och avvikelserapportering har funnits tillgängligt och legat till grund för arbetet.

Young children get affected and influenced by people?s thoughts and preconceived ideas about the difference between boys and girls. How they should behave and how they are supposed to play and interact with different toys.In the goals for what the school and teachers will achieve it says in the curriculum for preschool that teachers are supposed to counteract the traditional gender roles.To get answers to the question at issue, I collected 48 individual plans of development and I have performed four observations. I put all facts together and compared the results.The main result in this study shows that the traditional gender roles are being reflected in the children?s plans of development.

Abstract The purpose of this study was to find out how leisure educator´s reason about children?s learning and development, and their view of their own role in the process. Four leisure educators were interviewed to answer these questions. The study is based on qualitative interviews, wich means that the interviewer must interpret and understand what the respondents want to say. This is to get a deeper knowledge of the subject. The results show that the leisure educators believe they have a large and important role in children's development and learning.

ABSTRAKT Patienter spenderar generellt lång tid på akutmottagningen, och i samband med Akademiska sjukhusets LEAN-arbete för att effektivisera akutvården så gjordes denna tidsstudie. Syftet med studien var att undersöka hur lång tid patienter med bröstsmärta spenderar på akutmottagningen, hur lång tid det tar innan de blir triagerade och hur lång tid det tar innan de träffar en läkare. Könsskillnader och huruvida patienterna ankom i ambulans eller via reception studerades. Studien var en kvantitativ observationsstudie där 48 patienter deltog, 33 kvinnor och 15 män. Medelåldern var 56 år, och ålderspannet var 21 ? 91 år.
