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.

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. .

"Ett artigt pennekrig" En biografisk studie av Gustaf Montgomerys nätverk och författarskap under en period av ideologisk förändring och nya roller för författare 1812-1842

Studies of networks, fields and of communicative circulations complement each other. This master thesis is a biographical study of an author and journalist, Gustaf Montgomery GM, his network in Sweden of the early 19th century, and a study of his authorship and literary career. The starting-point of the study is GM:s change of field from the conservative to the liberal in 1832. The aim is to give explanations to this change and to describe how the change in turn effected the network. The method used is critical of sources.

Nervsjukdomar - Nästa stora satsning : Kartläggning av forskningsanslag i Sverige inomnaturvetenskap, medicin och life science

The aim with this project was to investigate how research grants in Sweden are distributed inthe selected fields; natural science, medicine and life science. Our client Olink producesdetection kits for biomarkers and our goal with this study was to give an indication of apossible new market area for their products. Three foundations were included in the study;VINNOVA, Vetenskapsrådet (Swedish Research Council) and Stiftelsen för strategiskforskning (Swedish foundation for strategic research). Nearly a thousand research grantswere analysed which included a total of 4,92 billion Swedish kronor. Seven selecteduniversities were contacted; Chalmers tekniska högskola, Karolinska Institutet, Kungligatekniska högskolan, Linköpings universitet, Lunds universitetet, Sverigeslantbruksuniversitet, Uppsala universitet.

Säkerhetsklassificering av IT-system på Fläkt Woods AB

This report presents a method for modelling a computer system from a security perspective. The questions that are going to be treated are:? 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.

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.

Utveckling av en Multi-Zonsmodell för NOx Bildning i Diesel Motorer

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

Användbarheten på högskolornas och universitetens hemsidor ur studenternas perspektiv.

Problemområde: En del av de högskolor och universitet som har hemsidor har inte lagt så stor vikt på användbarhet då deras funktionalitet brister. Det är svårt för deras studenter att på ett så enkelt sätt som möjligt nå den information de behöver. Hypotes: ?Användbarheten på högskolornas- och universitetens hemsidor kan förbättras med hjälp av att krav ställs från studenterna.? Genomförandet: För att undersöka hypotesen har tre undersökningar gjorts. Den första var en granskning av de utvalda högskolornas och universitetens hemsidor av författarna. Undersökning nummer två gjordes med hjälp av enkäter som studenter vid de utvalda högskolorna och universiteten fick svara på.

Twittra, gilla, mäta - En studie av åtta företags arbete med sociala medier

This thesis investigates and analyses the social media strategy of eight companies. How the companies measure and evaluate their activity and investments in social media channels in general, and Facebook in particular is studied through qualitative interviews. The findings are then compared and analysed. Findings indicate that companies' social media presences to a large extent are dependent on individual employees with high levels of interest for the area and that companies that have integrated social media into their others operations see more value from their efforts..

Genus och vetenskaplig kommunikation: en bibliometrisk studie av amerikansk biblioteksforskning
