Visualisering av Flight Recorder-data i Saab 2000 avionikrigg
The main purpose of a Flight Data Recorder (FDR) is to facilitate the investigation of incidents. In order to interpret the data that has been recorded in the FDR the data has to be visualized in some way. This can be done with software on a computer or with hardware that is specific for the model of aircraft that the data originates from.The aim of this project is to visualize data for six parameters from the FDR of Saab 2000 in an avionics rig. The avionics rig resembles the cockpit of Saab 2000 and the displays in it are identical to the ones found in the plane. All six parameters are shown on the same display.Due to safety regulation vital systems in aircraft are doubled, with one system on the left side and one on the right.
Jämförelse av funktionsbibliotek för JavaScript
När de traditionella skrivbordsapplikationerna görs om till webbapplikationer,
ställer det krav på JavaScript som används mer och mer för att få fram ett
responsivt gränssnitt på webben. För att underlätta utvecklingen av
JavaScriptapplikationer har ett antal funktionsbibliotek skapats.
I vår studie undersöker vi därför vilket av de två populäraste
JavaScriptbiblioteken idag, jQuery och Prototype, som presterar bäst i dagens
mest använda webbläsare. Dessa tester har utförts i ett testramverk som vi
själva utvecklat för att vara webbläsaroberoende och inte kräva något av de
bibliotek vi testar. Testerna är uppdelade i fyra testfall som körs 20 gånger
för
att ge ett mer tillförlitligt resultat. Vi har testat hur varje bibliotek
hanterar
traversering och manipulation av DOM-trädet, sätter och hämtar stilar och
attribut på element i DOM-trädet och hanterar event på element i DOM-trädet.
Testerna visade att biblioteket Prototype presterade bättre på alla utom ett
testfall i majoriteten av våra utvalda webbläsare; det enda testfallet där
jQuery
presterade bättre än Prototype var där DOM-trädet skulle manipuleras.
Konceptframtagning av pelletsförråd
This thesis work resulted in a template for how the thermal spray process can be controlled through robot programs. The robots today and their programs need to be replaced, therefore a new structure which can be matched with the new robot systems is needed. The work is limited to only concern structured programming on the new robots on Thermal Spray Centre (TC) with the programming language Rapid. The basic data for the program was retrieved from interviews with concerned personnel at TC, from studies on process parameters for thermal spray and from existing specifications at Volvo Aero Corporation (VAC). The thesis work briefly describes the process thermal spray and the four methods used at VAC.
Det digitala konstverket ?Eve?
Ambitionen och målet med mitt projekt var att visualisera delar av en
berättelse med hjälp av den senaste datortekniken. Detta tog sin form av en
3d-animation. Målet var inte att producera en färdig kortfilm utan att arbeta
med utvalda delar. Projektet var indelat i tre block; en planerings- och
researchfas, en produktionsfas och en reflektionsfas. Stora delar av
magisterarbetet har bestått av att producera innehåll som sedan ska analyseras.
Med arbetet vill jag att folk ska få mer förståelse för 3d-tekniken som ett
flexibelt och intressant konstverktyg.
Universell kunskapsorganisation: identifiering av ett framväxande forskningsområde genom citeringsanalys.
An ongoing discussion concerning the possibilities of universal classification based on phenomena rather than on research disciplines has been noticed. In order to discover if this was a limited discussion or the beginning of a major new field of research a study of citations was made using the database Web of Science. In addition, references of the works concerned were studied to find out where the ideas originated. The study of references shows that the ideas originate in a limited number of older published works, some of them well established in Information Science, some of them less generally known. The main ideas commonly used in Information Science are Ranganathan?s facet theories and the work of the Classification Research Group.
Hur blir politiska skapelser virala succéer? : En komparativ argumentationsanalys.
Since the beginning of the 1990s, Swedish society has gone through a great change. Firstly with the personal computer and then with the internet moving in to everyday life, a new arena for interaction with society evolved. Work, education, doing bank errands and reading or discussing the news, just to name a few, now all take place in the virtual world online. Not to mention social media sites such as twitter, instagram or facebook, the last of which has over half of the Swedish population represented as members. Companies, corporations, interest groups, political parties and politicians must be aware of the massive impact that a post spread through social media can have. This thesis will, with the text analyzing tool, argumentation analysis, and on the theoretical platform of political communications theory, analyze three of the most viral Swedish political posts spread over 120 000 times each, to see if there are any combined qualities that point to the fact that there is a formula for getting a post to become a viral success on social media. The main result showed that of the three posts analyzed, all were built up around a factual thesis, argued for with foremost example arguments, not only appealing to the logical branch of argumentation but also to the ethical, and that they tended to be of high relevance and sustainability. The conclusion must therefore be that these are all qualities that tend to be of relevance for making a political post on social media into a viral success..
Design, konstruktion och test av LED-spektrometer
A LED spectrometer has been constructed for qualitative spectrometry using certain wavelenghts. The LEDs and the photodiode are being controlled with a microcontroller that is connected to a computer to power the components and save data. The spectroanalysis made with the LED spectrometer were significantly different to a standard spectrometer, concluding that more analysis should be made until a final product is ready. Some areas of improvements are suggested. .

What defines a secure system and how does the company relate to these factors?? What are the threats today based on hardware/software, human factors and company routines/policies?? What measures should be taken for the organisation to reach a higher level of security for their systems?? How do we develop a method for classification of security and what components should it contain?? What changes are reasonable and necessary with the respect to the company?s resources?The report has been done through interviews and analysis of existing systems on Fla?kt Woods AB. From analysis of material, the aspects judged relevant to the subject and to the company?s needs, have been compiled to a document.
Mobile Ajax
This report describes a master thesis performed at SICS (Swedish Institute of Computer Science) and KTH (The Royal Institute of Technology) in Stockholm.Ajax stands for "Asynchronous JavaScript and XML" and it's not a programming language, but a suite of technologies used to develop web applications with more interactivity than the traditional web pages.Ajax applications can be adapted for mobile and constrained devices. This has been called Mobile Ajax. While the technique is the same, Mobile Ajax generally is considered to be a special case of Ajax, because it deals with problems specific to the mobile market.The purpose of this thesis has been to examine which possibilities and disadvantages has the Mobile Ajax from developers and users perspective. In addition we compare Mobile Ajax with Java Micro Edition (Java ME) and Flash Lite.This has been done through literature studies and development of a databased chat client (MAIM -Mobile Ajax Instant Messenger). The application sends and receives direct messages in real time between differently mobile devices.

Vid behandling av enkätsvaren har vi observeratatt informanternas systemtänkande var att betrakta som hårt och attde analogier som de tillfrågade hört talas om var uteslutandekonstruktionsanalogier.
Vägen till Bel Canto : Om min omskolning till Chiaroscuro
I am a practising classical soprano. After more than 20 years of professional singing, I re-trained my voice according to principles of the old Italian school of singing. In this essay, I examine the origins and priciples of bel canto, with special focus on appoggio and chiaroscuro, two key ingredients in the bel cantao tradition. I explore the relationship between science and the craft of singing, and what modern voice science has to say about the efficiency and health aspects of this technique, I also describe the profound effect it has had on me as an artist..
?Naturvetenskap finns ju överallt? : En kvalitativ studie av hur förskollärare på småbarnsavdelningar på Reggio Emilia inspirerade förskolor ser på arbetet med naturvetenskap
The purpose of the study was to determine the attitudes of the teachers of Reggio Emilia inspired preschools concerning the science work with children between the ages of one and three, as well as their opinions on how the physical preschool environment and the choice of materials influence their scientific work. The study was conducted in three departments of two different kindergartens. Although both kindergartens called themselves Reggio Emilia inspired, their working methods and their environments differed largely. None of them were originally built as Reggio Emilia inspired preschools. One of the kindergartens strived to design their indoor environment the same way as the preschools of Reggio Emilia are constructed, there for they were setting up different stations where the children themselves have the opportunity to explore various scientific areas.
Adoptionen av Affärsdriven SOA
Uppsatsen ämnar ge en indikation på huruvida affärsdriven SOA har adopterats i organisationer vilka har utfört eller planerat att utföra ett SOA-initiativ. Genom att karakterisera begreppet SOA via den litterära grund uppsatsen vilar på, har vi kunnat identifiera teman utifrån vilka vi utformat en intervjuguide i syfte att utföra en intervjuundersökning, i form av semistrukturerade intervjuer. Det empiriska materialet transkriberades och analyserades. Via meningskoncentration kunde vi sedan presentera informanternas syn på ovanstående syfte samt relatera detta till litteraturgenomgången. Detta resonemang blev till en diskussion för att därifrån nå ett resultat och således kunna ge ett forskningsbidrag.
