The aim of the essay is to be theory-testing as to see how a municipality/city which promotes itself as being ?green? motivates its efforts in the environmental area. Växjö city promotes itself as ?The greenest city in Europe?, an award appointed to the city by BBC and other international media.
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..

Våga vara dig själv : Att fo?rsta? och skapa en illusion av ljus med digitala medier
Vi omges sta?ndigt av ljus i va?r vardag, det finns naturligt ljus samt artificiellt. A?ven under de gra? dagarna finns det ljus och dess na?rvaro a?r alltid da?r a?ven om den inte alltid a?r som klarast. I detta kandidatarbete beskrivs ljuset ur olika synvinklar, men framfo?rallt hur Rembrandt och impressionisterna i sina konstverk anva?nt ljuset i sitt skapande.
?Var är du?? En studie om virtuella kollaborativa designprocesser i en studiemiljö
The design process of an interaction design student is mostly collaborative and computer oriented. Based on this, it?s hard to believe that we have not yet found a tool that will facilitate our needs. With this in mind, which elements do we need to promote collaboration in a virtual design process?
This thesis will include design processes, collaboration, creativity and virtual awareness, amongst others.
Automatisk trimning av drivsystemreglering från MATLAB
This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..
En jämförande studie mellan spikningsplåtsförband och WT-Tskruvar i limträkonstruktioner
Detta examensarbete har gjorts på uppdrag av Skanska Teknik med handledning av Johan Sjödin. Arbetets syfte var att jämföra olika limträförband, utförda av antingen spikningsplåtar eller WT-T skruvar, och komma fram till den bästa lösningen med hänsyn till bärförmåga, kostnad och utförandetid. I ett projekt har de spikningsplåtar, som används vid limträförband, börjat rosta under extremt fuktiga förhållanden fastän spikningsplåtarna är rostfria enligt tillverkaren. En fördel med WT-T skruvar är att de är gömda inne i träet och på så sätt inte i direkt kontakt med den aggressiva miljön, men även skyddad mot brand. Andra fördelar med WT-T är att utförandetiden är kort och kostnaden är lägre än spikningsplåtsalternativet.
En Modell av SOA för Agila Organisationer
In a dynamic and unpredictable reality, either rigid structures or silo architectures areappropriate ways to organize an agile organization. This thesis enlightens these relationsbetween Service Oriented Architecture (SOA) and an organization who acts in a varied andconstantly changing business environment. In other words, this thesis enlightens the question:?How suitable is SOA to organize the enterprise who will meet a constantly changing andheterogenic business environment?.The thesis presents a model where an efficient organization must be agile to be able to actquickly in the business environments with constantly changing desires, needs, expectations,desires etc. According to the same model a Service Oriented Architecture organizes theenterprise elements such as processes, resources, competences, responsibilities, informationsystems etc.
Effektiv och underhållssäker lagring av medicinsk data
Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..

Fodrets inverkan på resultatet vid undersökning av förekomst av ockult blod i avföringen hos hund :
Hemoplus® (Sarstedt, Nümbrecht, Tyskland) is a guaiac-based fecal occult blood test developed for human medicine. Guaiac-based tests make use of the pseudoperoxidase activity of hemoglobin so the test is not specific for human hemoglobin and can therefore be used in veterinary medicine. Peroxidase-containing foods such as meat (hemoglobin and myoglobin) can cause false-positive results of the test. To ensure that a positive result is not caused by diet, it has been suggested that canine patients should be fed a meatless diet for a few days prior to fecal occult blood testing. The aim of this study was to evaluate the effect of commercial dog food on guaiac-based tests.
In this study fecal samples from healthy dogs were analyzed with Hemoplus®.

Barnmorskors åsikter. Om frågor inför STI-provtagning
Bakgrund: Förekomsten av STI såsom gonorré, hepatit B och C, HIV, AIDS, klamydia och syfilishar under de senaste åren ökat i Sverige. Studier visar att långt ifrån alla som utsatt sig för smitta ellerhar symtom på STI går och testar sig. Dessutom visar studier att vårdpersonal ibland nekar individenSTI-provtagning trots att detta inte är tillåtet. För att underlätta barnmorskans arbete medanamnestagande vid STI har det utvecklats ett frågeformulär inför STI-provtagning. Det saknasdock information om barnmorskors åsikter vid användandet av frågeformuläret.Syfte: Syftet var att utvärdera barnmorskors åsikter om frågeformuläret ?Frågor inför STIprovtagning?på barnmorske- samt ungdomsmottagningar i Göteborg och södra Bohuslän.
Ungdomar och narkotika : En litteraturstudie om varför en del ungdomar prövar/använder narkotika
The purpose of this essay was to study factors that influence some youth to use narcotics. I wanted to increase my understanding and knowledge about these factors. I believe it is good to have such knowledge when you are working with youth who are using narcotics but also for a good drug-prevented work. It is a literary study, which covers the most frequently quoted results in the field of research.The questions for my study were:· Which factors influence youth to use narcotics on a individual level?· Which factors influence youth to use narcotics on a group level?· Which factors influence youth to use narcotics on a society level?My conclusion of this study was that youth often use narcotics because of many different factors and it is youth from all social groups in the society who are testing and using narcotics..
