Crescent evolve - Electric bike for youth

The purpose of the project was to design an electric bicycle to offer thetarget group youth an attractive alternative to mopeds. The basis for theproject was user studies in which young people were interviewed andobserved in their daily environment.The project resulted in a product, designed with the focus of integratingthe battery to the shape, to create a wholeness that is simple andintuitive.!The product is easy to use and operate, with an automatic transmissionengine.! A smart modular system allows the user to choose design withmudguards, rear rack, or without. The battery design is based on "cradleto-cradle" to maximize the battery life and minimize environmentalimpacts.It was very fun and rewarding to have the opportunity to present theresults for the youth who showed great interest in the product.The project was conducted in collaboration with Designit and Cycleurope..

Manga! Japanska serier och skaparglädje

This is a study of why Japanese comics, so-called manga, in such a high degree make Swedish readers eager to write and draw comics themselves, and what didactic implications this might have for teachers working in Sweden. To answer this, the author has put together a focus group of Swedish artists influenced by manga, and also used a questionnaire at two Swedish art schools, where young artists are taught how to draw in a manga style. The results show that it is the compelling storytelling and the focus on the characters that enthral readers about Japanese comics, but that it is the seemingly simple style that makes the readers think they themselves can master it. The fact that the interest in both reading and creating manga, almost completely overlap with the so-called period of oppression (between the ages of 11 and 14) when most students lose interest in creating art, is something that could and should be used in the Swedish educational system..

Bibliotekariers och ungdomars bild av sociala medier En kvalitativ studie av bilden av sociala medier hos bibliotekarier och ungdomar, och hur man kan förbättra bibliotekarieprofessionens förmåga att förmedla sig själv inom ett digitalt rum

Social media have become a bigger and bigger aspect of daily life for many ages and especially within the youth culture growing from digital interactions. At the same time libraries seems eager to use this medium to reach out to the youth to inform and to educate. But do we know enough about how these two groups? views each other to be effective at this work? And is it even something that is wanted? What?s the image of social media from their point of view?The goal of this study is to investigate the image of social media from the point of view of two groups, librarians and youth. The study is based on a qualitative approach with a random selection of candidates.

Utvärdering av den nationella söktjänsten LIBRIS

LIBRIS is a national library search engine offering information about 6 million books, articles, dissertations and other materials held by Swedish university libraries, research libraries and public libraries. In December 2007 a new version of LIBRIS was launched, developed with focus on usability, simplicity and accessibility. This thesis examines how the new LIBRIS is used, what is working well and what could be improved and also what the users think of LIBRIS. The following report is based partly on a study of usability and partly on a series of tests where librarians, scientists, students and developers have executed a number of tasks while thinking aloud. The users also participated in an interview.

Utvärdering och framtagande av åtgärdsförslag för de mindre avloppsreningsanläggningarna i Laholms kommun : En studie av fem avloppsreningsanläggningar upp till 500 pe

The aim of this project was to describe and to evaluate five small sewage treatment plants in the municipality of Laholm, Sweden, in order to investigate the treatment efficiency and to evaluate if effluents comply with discharge permits. The treatment systems were designed to treat effluents from 90 to 500 population equivalents. A report on the design and the present state of each sewage treatment plant has been made. This was made based upon previous documentation on water quality and by new sampling campaign as there were only a few previous measurements. Data has been evaluated and remedial actions proposed for those treatment plants that don?t fulfill discharge permits.

Biggi förvaring : förvaringsskåp för utomhusbruk

Manne Bouveng, CEO of Optimel AB had an idea for a new kind of storage cabinet that could be adapted especially for townhouse owners. I came in contact with Manne by a familiar friend for us; we met and decided that it would suit as my thesis.What was needed to be done was a market research that would possibly show that there was a need for a new kind of storage cabinet on the market. Because of this we continued to work on the basic idea. We came up with a solution where we developed a box that resembles Optimels known mailbox Biggi Rondo, the storage cabinet is a new solution of a storage cabinet, adapted after a market that need of a lot of new space. The solution is based on a simple construction which sits an inside hang-off device which can attach tool hooks, tool holders and shelves and so on.The purpose of the assignment was to develop a new type of storage cabinet with some kind of solution to attach tools and other garden related stuff. With this we have succeeded and the concept meets the requirements we set ourselves at the beginning of the project..

Kinetisk Keramik

Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..

Simbase: ?Simulator Base Package?

The purpose of this work is to providing a general set of base classes for building simulators, for example a robot system. Instead of every time building a new simulator from the beginning, you get the already completed components from a library. The library should in that way act as a springboard for development.To do this work, there?s a lot of knowledge required in how a general robot system could look like. Therefore it was necessary to gather some information about robotics.

Att designa användargränssnitt för äldre människor med afasi

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

Pedagogers uppfattningar om den fysiska miljön i förskolan : En intervjustudie med pedagoger från olika pedagogiska inriktningar

In recent years, the demands for effectiveness and evidence in social work have increased in all work areas, including that of healthcare. This has sparked the discussion on concepts such as practical- and theoretical knowledge and their respective roles in social work. In the light of this, the purpose of this candidate thesis is to investigate healthcare social workers understanding of practical- and theoretical knowledge in the working process as well as their respective influence and importance. This candidate thesis is based on three interviews with social workers from different departments in Norrlands Universitetssjukhus in Umeå, Sweden. To provide range to the thesis, the interviewees were chosen from a purposeful sampling.

Autonom bil med enkapseldator och ultraljudssensorer : tillämpning av en Arduino mikrokontrollerplattform och HC-SR04 sensorer

 Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.

Utvinning av volatil-data : En jämförelse av olika verktygs påverkan på Windows XP och 7 vid en volatil-data-utvinning

Examensarbetet går ut på att utreda vad verktyg vid volatil-data-utvinning (Reeve & Shipley, 2006) orsakar för förändringar på ett datasystem. Volatil-data är information som försvinner när datasystemet stängs av och kan vara nödvändig t.ex. när man försöker läsa en krypterad hårddisk, då krypteringsnyckeln (Casey, et al., 2011) kan finnas i (Random Access Memory) RAM-minnet som är volatilt. I IT-brottslighetens barndom utvecklades (Brown, 2009) metoder för att påverkan på ett datasystem vid ett beslag skulle bli så liten som möjligt. Detta gjordes för att beviset man får från datasystemet skulle hålla i en rättgång och gick ofta ut på att slå av strömmen på datasystemet.

Bildförbättring över en bildsekvens

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.

Samuel Klingenstierna: Spel och sannolikhetsteori

In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.
