På senare år har spelmöjligheterna och aktiviteterna på Internet exploderat kraftigt och indikationer visar på ett ökat spelintresse. Syftet med detta examensarbete var att, med hjälp av en webbenkät, undersöka förekomsten av programstudenters nätspelsvanor vid Luleå tekniska universitet. Antalet programstudenter som genomförde webbenkäten, vilken baserades på South Oaks Gambling Screen (SOGS-R), var 675 och av dessa hade 252 satsat pengar på nätspel. Resultaten visade att de programstudenter som nätspelar utan problem var ca 31,8%, problemspelare ca 3,7% och troliga spelberoende/patologiska spelare ca 0,8%..

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Water is vital for all life on earth. But it can also be dangerous, even fatal, if it is polluted water. 60 percent of child mortality can directly be deduced to dirty water. Not only developing countries are affected, even in the western world epidemics are breaking out by partake or bathing in dirty/polluted water.MIP, Molecularly Imprinted Polymers, is a biosensor technology that can provide faster and more reliable response than the current methods of water analysis. It is also cheaper and due to that more samples can be taken and analyzed.

This 3d navigation application is a part of a project that helps the user to learn and find the right position on a map with many exercises, the user has a compass nearby that he/she can use to find the position that requires to get the right answer on that particular exercise. Macromedia's Director is used for the creating of the program, where Lingo has a importent part as the script language for the scenes in Director. A 3D scene is build up with codes in Lingo, a few 3d models and serveral overlays are created and displayed on the screen. Different kind of textures from pict files are is representing the overlays and put on the 3D models. That give the user a more pleasant experience when going through the exercises that helpes the user when he/she is going to navigate on a boat at sea..

Syftet var att undersöka om exponering inför emotionella röster påverkar muskelanspänning och hjärtats slagfrekvens samt om det finns en samvariation mellan storlek eller längd på muskelanspänning vid aversiv emotionell input och grad av alexitymi. 24 studenter lyssnade på arga, glada och neutrala röster samtidigt som muskelanspänning mättes med EMG och hjärtats slagfrekvens med EKG. Grad av alexitymi mättes med Toronto Alexithymia Scale 20. Resultaten visade att arg eller glad röststimuli gav större muskelanspänningen än neutralröststimuli. Ingen skillnad i muskelanspänning fanns mellan arg eller glad röst.

Denna rapport är ett inledande steg mot att förbättra arbetsmiljön för svetsare vid påsvetsning med Uddcomb Metoden i massakokare. Syftet med rapporten är att analysera problemet med värme och dålig luft samt förklara hur och varför problemet uppstår. I arbetet ingår även att ta fram olika lösningar för att slutligen hitta ett komplett system för ventilation och kylning. Den föreslagna lösningen består av ett integrerat kylsystem och ett koncept med mindre fläktar, kallade torpeder, som monteras på arbetsplanen vilka driver ut varm och smutsig luft snabbare ur kokaren. Den föreslagna lösningen utreds även ur ett ekonomiskt perspektiv.

ROS är ett produktnära system som stödjer planering och återrapportering i stålverket. Sandvik vill undersöka möjligheterna att modernisera användargränssnittet på detta system som idag är terminalbaserat till ett modernt grafiskt interface.

Resultatet från analysen visar att Web Services Integration Toolkit klarar av att uppfylla de mål som är satta. En testkörning av Web Services Integration Toolkit görs också på ROS och resultat visar att metoden fungerar även fungerar i praktiken..

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.

Syfte: Rapportens syfte är att kartlägga om upplevelsen av ett rum kan förändras beroende på om och vilka ljud som spelas upp i rummet. Metod: I samband med en ljudinstallation på Plattan vid Malmö Högskola har rörelsemönster och beteende för Plattans besökare observerats. Dessutom har flera besökare besvarat en enkät. Resultat: Inga eventuella förändringar i rörelsemönstret eller beteendet för Plattans besökare kan ses som en konsekvens av ljudinstallationen. Det finns inte heller någon skillnad i enkätsvaren beroende på installationen. Slutsats: Resultatet ses som en konsekvens av bristfälliga forskningsmetoder. I rapportens slutsats bildas hypotesen att en installerad ljuddesign inte är en tillräcklig åtgärd i den undersökta typen av miljö.

The report aim to increase awareness of factors that have a major role whenremodelling an apartment building from the 1950s to offices.The thesis can be used for future projects when remodelling apartments to offices.The report can provide ideas and inspirations on how this can be done in aneffective way, ie . A way that does not require rebuilding the supporting structure,but only non bearing walls. The thesis also gives insight on the parts that will needto be supplemented from Boverket?s requirements in terms of accessibility,acoustic and fire requirements.The methods used in this thesis are literature studies, case study and sketch work.In the literature studies, the primary sources were Boverkets byggregler BBR, andArbetsmiljöverkets föreskrift AFS 2009:2 but other literature were also used. Theprimary items were chosen from the literature studies and they were furtheranalysed in the sketch work.

The purpose of this thesis is to study the usage of and attitudes towards electronic books among graduate and PhD students at Karlstad University. The main questions are: How do graduate and PhD students use electronic books? To what extent are electronic books used compared to printed books? To find the answers, a user study was carried out at Karlstad University library. The results show that a majority of the respondents are aware of the possibility to use electronic books but prefer to use printed ones if they have to choose. Many respondents also complained about difficulties reading a text on the computer screen.

This study explores Environmental Storytelling techniques and whether these can beused in combination with each other to lead a player through a game scene in aspecific pattern, affect the player?s narrative and exploratory view and explorewhether Self-paced Exploration can be combined with these techniques.It is a qualitative study conducted by six gaming sessions with accompanyinginterviews in which six people get to play one of three versions of the same gamescene. The only differences between the scenes are the different guidance techniquesused. The informants' movement patterns are identified and interviews recorded byaudio, as well as screen recording. The results shows that Environmental Storytellingtechniques can very well be used to control the player's exploration patterns, bothnarratively and navigation purposes and Self-paced Exploration can be utilized to agreater efficiency in combination with these..

My work has been to create a magazine for iPad to explore this format, whichthere are mixed feelings about. Instead of seeing the digital format as an enemy ofthe printed magazine, I have chosen to see it as an opportunity.I have given myself the task of designing a magazine that can justify the useof the digital magazine. I have looked at the identity of the magazine, but mainlyexplored the format and its prerequisites.I was triggered to do the project when I saw people who are just making a pdfof the printed magazine and publish it digitally. I have during my work discoveredhow near or far away you can be from the printed magazine.The format of the iPad has multiple aspects to look upon; one that turned outto be clear in my project was navigation. Working with a spread has its problemsand opportunities; the same applies to an article that is larger than a screen.
