Integrering av belysning i ytterdörr
Our thesis is conducted in collaboration with Draper Europe AB in Halmstad.The goal of the project has been to construct a baseline concept for the instaling of aprojector screen. Draper Europe AB, in the curent situation, have several kinds of fabrics and designs on their sceens and the cases they are in. Today if you select a screen you can´t chose the design and function of the sceens case.The arrangement of the components inside the cases was to be constructed so the assembler simply could move them to different cases. To make it even easier for the assembler and to save time, the desire of less component was mentioned. Another problem that needed to be solved was the mounting of the projectionscreen at the customer place.
Ljudreducering av värmepump
This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..
Application development for touch-screen interfaces
The way we interact with computers will soon change dramatically. The input
interfaces are becoming more and more intuitive and one of the latest
technologies is a touch screen interface capable of dealing with multiple
inputs simultaneously. The tools we use to communicate with the computer -
such as the mouse and the keyboard, will slowly disappear and be replaced
with tools more comfortable and more natural for the human being to use. The
purpose of this project was to create a basic framework for future projects
dealing with this interface, as well as creating some example programs. This
report describes my work and my experiences with this new interface..
Tidssynkronisering av information i second-screenapplikationer
I denna uppsats undersöker vi hur tre olika tidpunkter för visning av information på en secondscreen uppfattas av personer. Målet med undersökningen är att få en inblick i hur tittare upplever information som visas på en second-screen. Vi hoppas att resultatet ska kunna bidra till utformingen av kommande second-screenapplikationer. Dessutom har vi undersökt om tidpunkten av när information visas påverkar minnet av det personer ser på second-screenen. Vi utförde tester på totalt 18 personer med hjälp av tre stycken prototyper och varje testperson blev intervjuad efteråt..
Passive acoustic diver detection
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.
Perceptuell och akustisk bedo?mning av ro?stfunktion hos barn med tonsillhypertrofi : Effekter av kirurgi
In Sweden over 10.000 patients annually, mostly children, undergo tonsillar surgery. The most common surgical method is total removal of the tonsil, tonsillectomy (TE). During the last decade partial tonsil resection, tonsillotomy (TT), has been reintroduced and is associated with lower primary morbidity and less postoperative pain. The aim of the present study was to evaluate if and to what extent 4-5 year old children?s voice function are affected by tonsillar hypertrophy compared to controls and to study the effects of the two surgical techniques on vocal function.
Eyjafjallajökull
Eyjafjallajökull is made of textile, ash and pigment. Itis a publication which tells the story of the ash cloudthat stopped Europe. The primary goal of the projectwas to use textile as material and screen printing asmethod to present the story of Eyjafjallajökull. Theaim was to examine the relationship between artand graphic design. As the material and printingmethod was set from the beginning the processwas inverted: The information needed to fill thepublication was produced to fit the presentationand not the other way around.
Säg det tydligt! : Stil i text på webben
AbstractWrite the most important things first in text that will be read by a scanning web user. This paper is based upon theories about? how we read? what style in texts is? how texts should be written for web pagesReading from computer screens is about 25 percent slower than reading from paper. This because screens? flicker? have lower resolution than paperAll text with the purpose of being read from a screen should be adjusted to the reader?s physical condition.
Universell Design - en användbarhetsutvärdering av MyTobii C-series Control
Universal Design is a well established methodology with the fundamental purpose of designing products to be usable for as wide audience as possible, without the need of special adjustment to suit the individual. In this essay, Universal Design has had a clear influence in both the process and the result. The choice to use Universal Design as methodology in this usability evaluation, has essentiallv to do with the target audience.As a part of the design process of MyTobii C8 has Tobii Technology ask for a usability evaluation. MyTobii C8 is an 8" touch screen computer with a windows based operating system which will initiate the software MyTobii C-Series Control. MyTobii C-Series Control is the control panel for MyTobii C8, whose interfaces constitute the platform for various modificarion of the unit.
Att utveckla en modern webbplats : A?r responsiv design framtiden?
The IT industry is constantly evolving and it's more or less a requirement today for web developers to be familiar with and to be able to develop for all platforms. A technique that has taken hold and is now widely used is responsive design. Developing responsive design means adapting the layout to the viewing environment; the screen size. Another useful method when developing for different devices is the mobile first theory, which means developing for the mobile screen first. This is done to scale down the site and to clear unnecessary information in order to provide a better user experience.
"Surfnacke"- ett växande hälsoproblem bland ungdomar? : Skärmbaserade aktiviteter, fysisk inaktivitet, muskuloskeletala symptom och smärtintensitet
The aim of this study was to analyse ninth graders self reported screen based activities, sedentary time and musculoskeletal symptoms and pain intensity. The other aim was to examine changes regarding musculoskeletal pain and inactivity between ninth graders from a cross sectional study in year 2004. To meet this aim, following questions were designed: How is the relationship between screen based activities, inactivity, musculoskeletal symptoms, pain intensity and differences between girls and boys? How have musculoskeletal symptoms and screen time changed since year 2004?Method: The method used for this study was a quantitative method. The research was carried out using a questionnaire that was answered by pupils from 11 schools from all over Sweden.

Kellersson E, Jämförelse av andningsmuskelstyrke mätning på ny utrustning. Examensarbete i biomedicinsk laboratorievetenskap 15 poäng. Malmö högskola:
Hälsa och Samhälle, enheten för biomedicinsk Laboratorievetenskap, 2012.
Svaghet i andningsmuskulatur är vanligt hos neuromuskulärt sjuka, lungsjuka och hos vissa patienter som behandlas med steroider. Vid neuromuskulära sjukdomar utgör en progressiv försvagning av andningsmusklerna (främst diafragman) det allvarligaste hotet mot överlevnad. Andningsmuskelstyrkan kan mätas med hjälp av en spirometer, där det maximala inspiratoriska trycket (PI max) och det maximala exspiratoriska trycket (PE max) mäts med hjälp av tryckreceptorer vid en pnemotachograf.
En anpassningsbar applikationstruktur för flerpunktspekskärmar
Klassisk mus-interaktion har begränsningen att bara en punkt kan aktiveras på skärmen i taget. Interaktionen med de flesta applikationer blir, på grund av detta, sekventiell vilket kan vara en begränsning eftersom människan är van att utforska problem simultant med båda händerna. Flerpunktspekskärmar är en relativt ny teknik som möjliggör nya interaktionsmöjligheter där flera pekpunkter kan vara aktiva simultant. Det här examensarbetet fokuserar på problemen kring att skapa en applikation med användargränssnitt för flerpunktspekskärmar. Applikationen som utvecklats har en grundstruktur vilken är möjlig att vidareutveckla och på så sätt anpassas för att passa nya behov, till skillnad från de implementationer som granskats vid förstudien vilka fokuserar på att lösa specifika problem.
Barnröstens förändring under dagen i en anpassad röstinspelning och spontantal : En experimentell studie av perceptuella och akustiska parametrar
A controlled recording in a studio is the basis of all voice treatment. However, this controlled way of recording voice patients' voices can be questioned. The voice use may be different in a natural environment. In children noise related voice problems are investigated in a study about voice and its development (BUG ? Child voice and noise).
Skogens Eko
Naturen inspirerar mig, i detta projekt jobbar jag med strukturen hos trädstammar och bark, och översätter det jag ser till vävda textiler. När jag befinner mig i naturen känner jag mig ofta lugn och kan koppla bort allt annat i min omgivning. Det lugnet vill jag återskapa och föra in i en rumslighet. I barkens olika strukturer såg jag intressanta varierande ytor som jag ville jobba med i textil. I mitt examensarbete har jag designat textilier med uppmätt akustiska egenskaper för offentlig miljö.
