This report describes a thesis project on 15hp. The purpose of the thesis project is to build a laser projector that reacts on sound waves and thus get a laser beam to draw visualizations of sound waves on a wall. The idea was that the design would be independent and not have to be plugged into any audio equipment. This was achieved by absorbing sound waves into a microphone. Another factor was to get a ?do it yourself? -feeling of the design and therefore it was chosen to be constructed using for example, old hard-drives.The result was a relatively large and bulky designed laser projector that can draw sound waves on a wall..

Min uppsats handlar om hip hop som ungdomsfenomen. Syftet är att belysa breaking som en del av hip hop-kulturen och vad breaking består av. Hip hoppens utveckling och kulturella drag i relation till hip hoppens fyra element rapmusik, breakdance, dj: s och graffiti beskrivs. Jag har också undersökt vad breaking betyder för utövarna och vad de vill uttrycka med dansen. I mitt resultat sammanfattas mina observationer, intervjuer och studier av texter.

The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..

The purpose of this paper is to investigate how staff at secondary schools are thinking and reasoning about notifications to social services based on norm breaking behaviors in students. To find this out five qualitative interviews has been made with counselors in two public schools and three private schools in Örebro län. The results show that there is no clear definition of what norm breaking behavior is which making the reasoning difficult. There are clear procedures for the staff to dealing with norm breaking behaviors but they do not know when they will be applied. The decision to report behavior to the social service is usually not taken individually, it is a result of several people?s views and experiences.

Denna rapport beskriver två nya begrepp inom speldesign; kompakt leveldesign och planerad sequence breaking. Fokus ligger på kompakt leveldesign, och har definierats som att innehålla följande tre element: Hög rumslig desnitet, lager, och backtracking. Planerad sequence breaking definieras som en mer subtil variant av alternativa rutter. Begreppen står som dels underlag för fortsatt diskussion om ämnet, då de inte förekommer i tidigare litteratur, och dels som ett sätt att förhålla sig till leveldesign som designer.Vidare beskrivs spelet Ittle Dew, vilket har skapats tillsammans med Daniel Remar i avsikt att implementera ovanstående koncept. Speltester visar på hög grad av nöjdhet hos spelare, och implementationen anses således ha lyckats väl.Författaren uppmuntrar till användandet av kompakt leveldesign i andra verk, med förbehållet att inte tumma på mer traditionella riktlinjer..

Jetströmmar betyder mycket för meteorologer och fungerar som ett hjälpmedel för prognostisering av lågtryck. Kvadrantmodellen för jetströmsstråk beskriver hur det kan bildas lågtryck och konvergens vid marknivå på olika sidor om jetströmmen. Jetströmmar är också av betydelse för flygtrafiken, eftersom man kan spara tid och bränsle genom att flyga in i ? eller genom att inte flyga in i ? en jetström. Det är känt att jetströmmar ibland kan ge upphov till klarluftsturbulens (CAT), och studier har visat att turbulensen ofta är associerade med stabilt stratifierade zoner i närheten av jetströmmen.Denna studie börjar med en teoridel där jetströmmars uppkomst och kvadrantmodellen redogörs.

The aim of this study is to investigate how 20 children discusses norm breaking based on a children?s book with a focus on following questions:How do the children discuss norms based on the children?s book?Are there differences in opinions and comments between children with Swedish as their first language and children with Swedish as a second language, and if so, which ones?The investigation is based on four discussions of children?s literature, which are a method Chambers (2004) means enable the children to put their thoughts and feelings about the book into words.The theoretical frame of the study is founded on post-structuralism feminism and particularly Butler (Ambjörnsson, 2010) and Davies (2003) theories about gender and gender roles.The investigation shows, among other things, that the children are basing their discussions on the norms accepted by the society. But it also shows that there are differences in the way that the children with Swedish as a first language and Swedish as a second language discusses norm breaking. .

The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.

The curious nature of humans has been the puzzle of psychologists, philosophers and scientists since the time we began to use those terms. Why are we curious? Why do we behave the way we do and why? The span of views on curiosity covers all. From being viewed as part of our animalistic nature and compared to instincts, to be viewed as a virtue to scientists and the reason behind why we explore space. Behaviorists tried to define it as an innate drive and some say that it has a crucial role in our ability to learn and understand.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

This study is inspired by research about alliance as a common factor. The purpose is to explore the positive experiences among community-based social support workers when breaking the rules with their clients. The study questions in which situations they broke the rules and how they handled these situations related to their clients and colleges. Qualitative, individual interviews were made with four community-based social support workers who had such experiences. The results were analysed through an hermeneutic approach using Johan Asplund's theory of social responsiveness.

This study is of a qualitative phenomenological approach. Its background lies in recent reports that show the problem of self-harm increasing among adolescents. The intent of the study was to highlight school counselors? view of self-harm, and their experiences of meeting self-harm through their work. Six school counselors, all employed in secondary school, have participated in semi-structured interviews.

The purpose of this essay is to examine the construction of the norm-breaking characters Saga from the young adult novel Tusen gånger starkare written by Christina Herrström and Pippi Longstocking from the books written by Astrid Lindgren. In order to do this I have applied queer theory as well as theories of narrative in my analysis.To be able to study the breaking of norms, it has been essential to first examine the way the norm itself is manifested in the books. Because of this I have chosen to begin my analysis with an examination of two other characters who by their normative behavior contrasts against Pippi and Saga, namely Signe and Annika. The understanding of the normative discourse that Signe and Annika represent is crucial in understanding the way Saga and Pippi later turn against it.After that I examine in which ways Saga and Pippi breaks prevalent norms and how they as characters are constructed as being different. Subsequently I study the effects of Saga?s and Pippi?s norm-breaking, taking focus on how it influences Signe and Annika.Finally I discuss the view of Saga and Pippi as subversive characters, and however the books can be said to have a subversive effect.

One task of school is to counteract traditional gender patterns. Literature is an actor which can affect people?s perceptions of what is feminine and what is masculine. It can therefore be worth looking at the works of fiction that are available for pupils in school. A book that is popular among children and adolescents is Twilight (2007).
