Uppgradering av robotsystem på Termisk sprutning, Volvo Aero

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.

Kroppstemperatur och vattenavdunstning via huden hos extremt underburna barn vid vård i kuvös och med kängurumetoden

Aim: To examine the reaction of extreme preterm infants with regarding to body temperature and transepidermal water loss during skin-to-skin care according to Kangaroo Mother Care (KMC) during the infant?s first week of life. Method: This was a descriptive quantitatively designed study, which was a pilot study within the framework of a larger project. Nine children, with a median gestational age of 24.91 weeks, were examined by measuring body temperature (axilla and skin temperature) as well as transepidermal water loss before, during and after KMC. Results: The study showed that skin temperature tended to rise during KMC, especially for those children who were nursed with KMC for more than 60 minutes.

Testdriven utveckling

I programmeringsvärlden har en ren, enkel och testbar kod en stor betydelse. Detta examensarbete avslöjar ett nytt koncept vilket kanske är den viktigaste upptäckten inom metodområdet på senare tid, så kallade Testdriven utveckling (TDD). Testdriven utveckling är ett sätt att utveckla mjukvara och det som utmärker den är att man först skriver ett test som inte ska fungera (röd fas), sedan skriver man en kod, så enkelt som möjligt, som gör att testet ska fungera (grön fas) och till slut ska man våga göra förändringar även om koden fungerar, om man är inte riktigt nöjd eller om man helt enkelt vill optimera sin kod (omstrukturera fas). Syftet med studien var att utvärdera vilka fördelarna och eventuella nackdelarna är med den här typen av mjukvaruutveckling, att motivera varför det är lämpligt att välja den och att visa hur man gör med hjälp av Java, JUnit och Eclipse. Material som användes i studien insamlades genom litteratursökningen och intervjuer.

Metoder för användardriven gränssnittsprogrammering

När användare bestämmer sig för att utveckla gränssnitt till sina system sker detta via någon form av verktyg. Vi måste avgöra vilken utvecklingsmetodik som ska användas och hur vi kan tillföra mer funktionalitet för att systemet inte ska bli föråldrat. För att svara på detta bryter vi upp arbetet i två delar. I första delen undersöker vi vilken programmeringsmetodik som lämpar sig bäst för gränssnittsutveckling genom en undersökning i två delar. I andra delen ser vi över vilka lösningar som existerar för att implementera ny funktionalitet till ett verktyg för att sedan presentera en egen lösning..

Oljeprischocker ? En studie på de svenska och brittiska aktiemarknaderna

ABSTRACT TITLE: Oil price shocks impact on the British and the Swedish stock markets SEMINAR DATE: 2007-06-07 COURSE: Bachelor thesis in Business Administration and Economics, 10 Swedish credits (15 ECTS) AUTHORS: Carl Hersaeus, Sven Piehl Trygg ADVISORS: Hossein Asgharian, Göran Andersson KEY WORDS: Dummy Variables, United Kingdom, Oil Price, OLS, Regressions, Stock Markets, and Sweden PURPOSE: The purpose of this paper is to study whether, and how, oil price shocks have an impact on British and Swedish stock markets. METHODOLOGY: Our paper is based on secondary data, focused on historical spot prices on Brent oil and stock indices from Sweden and UK. We construct dummy variables to register positive and negative disturbances in the oil price. Furthermore we try to find a relation between the price disturbances and the different stock indices. THEORY: We take off from earlier studies, which prove that there is a relation between oil prices and stock markets.

North European Gas Pipeline : Ett säkerhetshot mot EU och dess medlemsstater

Extreme Production Makeover? fångade vårt intresse för en tid sedan, strax innan vi skulle börja skriva vår C-uppsats. Metoden går ut på att under mycket kort tid förändra och effektivisera en produktionslina för att höja produktiviteten. Vi blev genast nyfikna på om Extreme Production Makeover? skulle gå att omsätta i administrativa flöden och tjänste-flöden med ett informationslogistiskt perspektiv.Inom produktion finns det en lång tradition av att arbeta med effektiviseringar och förbättringar.

Utveckling i Java av ett pedagogiskt spel i kvantfysik

The game QuantoJump is developed in the programming language Java to be an educational game in quantum physics. By illustrating quantum mechanical laws of electron transitions with shapes and colours, QuantoJump hopes to spark interest and create a more intuitive understanding of quantum physics. The result is a game where the player plays as an electron in the outermost shell of an atom, with the goal of getting to the innermost shell. This while not making forbidden jumps by following the laws of electron transitions dictated by quantum physics. The programming of the game was done in the integrated develpoment environment Eclipse.

Utvärdering av grafisk utvecklingsmiljö för programmering av signalprocessor

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

Ström- och temperaturkontroll

Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

Sammanfaller staters intressen i ett samarbete? : En fallstudie om Frankrikes och Tysklands ställningstagande till Israel/Palestinakonflikten före och efter införandet av GUSP

Grafisk utvecklingsplattform för signalbehandling - Design och implementation

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

Aggressivt utagerande: Betydelsen av samtidig förekomst av callous-unemotional traits och impulsivitet

Abstract  The importance of the co-occurrence of callous-unemotional traits and impulsivity concerning aggressive acts was examined by a survey. The participants consisted of 1478 Swedish youth. Three groups with extreme scores on callous-unemotional traits and impulsivity was identified.  The group scored high on both was more prone to show higher levels of aggressive and conduct problems behavior compare to the other groups. The aggressive and conduct problem behavior was shown at higher level in all examine variables. This study highlight that impulsivity can identify extreme aggressive individuals, without taking HIA (Hyperactivity, Impulsivity and Attention) problem as a entirety, to account, if shown with callous-unemotional traits. Keywords: Callous-unemotional traits, impulsivity, aggressive, conduct problem, youth, co-occurrence..

Risk management i läkemedelsindustrin : Hur användbara är optimeringsmodeller vid urval av projektportföljer?

Risk management har historiskt sett associerats med riskminimering och undvikande. Men framför allt inom project portfolio management har ett skifte inletts mot ett proaktivt tillvägagångssätt för att hantera risk, snarare än reaktivt. På så sätt uppnås en holistisk analys av risk som tar hänsyn till både positiva och negativa avvikelser på mål. Syftet med detta arbete är att undersöka hur användbara optimeringsmodeller är i läkemedelsindustrin ur ett risk management-perspektiv. Modellerna som undersöks är capital budgeting problem, goal programming och contingent portfolio programming.

PixelCity Sharp-X : Jämförelser ur utvecklarperspektiv mellan C++ med OpenGL och C# med Direct3D

This essay serves to illustrate the main practical differences between the popular medium-level programming language C++ (C Plus Plus), and the newer high-level language C# (C Sharp). It will focus on the aspects that are readily apparent to the application programmer, such as differing syntax, constraints and capabilities.It will also feature a similar comparison between the open source OpenGL graphics library, and the proprietary Direct3D graphics library owned by Microsoft Corporation.It will not go into the differences in ?under the hood? mechanics that the application programmer seldom have to consider after having chosen his programming language or graphics API, such as C# being compiled into an intermediate language and is run on a virtual machine where C++ is compiled directly to machine code, or the differing principles of rendering in OpenGL and Direct3D.This is by no means comprehensive, many things have been left out or overlooked..

IT-stöd för riskhantering : En studie av risk och kvalitetsarbete vid ZERT AB

This paper presents a project and literature overview about how risk management and quality sometimes goes hand in hand and sometimes in two different directions. Meaning that the risk management can affect product or process quality differently depending on what risks an organisation chooses to control.The purpose with this paper is to get a deeper understanding about how risk and quality works together with IT-support and therefore we have been actively participating in a project with a risk management company called Zert. A literature study and a qualitative interview study have also been undertaken to see what the customers and the other researchers have written, to be able to make proper conclusions on the subject.To easily work together and get the information that was needed, four methods where used. Besides the qualitative interview and literature study the think-out-loud, card sorting and a variation on the Extreme Programming method where used to help visualize and improve communication both with Zert, the costumers and among ourselves.Zert is a risk management company that helps other organisations to control their different types of risks that they might be taking, by offering a system where the risk management process is held and providing consulting services by helping within the processes. Both Zert and their customers see the communication, knowledge and teamwork as something important as well as the quality within the work, processes and the end result.
