I både kvalitets- och kontrollarbete finns det behov att kunskapsmässigt komma så nära verkligheten som möjligt vid fastställande av defektparametrar för oförstörande provning (OFP). Orsaken är att olika acceptanskrav och bedömningsgränser är svåra att klarlägga när man inte kan förlita sig på att uppgifter är realistiska. I projektet har olika erfarenheter använts för att få en bättre helhetsbild i området för defektparametrar och oförstörande provning.Denna rapport redovisar den inledande delen av forskning och utvecklingsprojektet PLANT 2, där olika defektparametrar kartlagts och en teoretisk bedömning utförts med avseende på hur signalsvaret påverkas för OFP-metoderna virvelström (ET) och ultraljudsprovning (UT) i form av puls-eko (PE) och ?time-of-flight-diffraction? (TOFD).Definitionen av redovisade defektparametrar följer i stort SKI-rapport 95:70 [1]. Defektparametrar i denna rapport redovisas i bilaga 1.Vid bedömningen av defektparametrarnas inverkan på OFP-tekniker, har drift¬inducerande defekter och tillverkningsdefekter hanterats separat.

This paper is about the new programming language from Microsoft, C# (See Sharp) and the .NET Framework. They are still in beta-version, but will be released on the market in February 2002. This paper presents C#, not in detail but the characteristics that distinguish the language. A comparison is done with C++ and Java, since C# is most resembling to these languages. Both C# and Java have been developed from the mother- language C++.

This thesis describes how the chip space and coolant channels are designed in today?s mills, the ideas behind the design and what is considered to be the best method of cooling. It contains ideas on how the chip space can be simplified. It contains several concepts on how the cooling could be designed for better efficiency and manufacturability. There are also suggestions on how the cooling could be stopped when the cutter isn?t cutting.

Uppsatsen behandlar olika aspekter inom integrationsprocessen vid företagsförvärv. Företagsförvärv är synnerligen vanligt förekommande i Sverige idag och inte minst i IT-branschen. Genom denna fallstudie av två förvärv inom IT-branschen ges en överblick över vilka fallgropar och problem som kan finnas med de mjuka aspekterna i en integrationsprocess. Denna magisteruppsats är en kvalitativ studie av integrationsprocessen inom områdena Organisationsstruktur, styrning och ledarskap, Kommunikation, Kulturskillnader samt Kompetensförsörjning. Undersökningen har genomförts genom intervjuer och enkäter vid två IT-företag, Alfa och Beta (dessa företag samt respondenterna är anonyma).

This report is about finding the cooperative elements in games and making a boardgame based on them. I tested different computer games and boardgames to try and get the cooperative elements and then I make a boardgame based on what I found.What I found during testing is that to be a fully cooperative game all players on the same team must win or lose together and one player should not be able to finish the game by herself. There are of course some things that can change this for example what kind of players are playing.My best advice is that you should decide that the game is fully cooperative from the beginning and build the game from that..

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

When performing studies that test the reactions of horses in different situations, important information may be available about the horse?s reactivity level. With information from these tests, accidents and dangerous situations may be prevented. When the behaviours from tests are compared with race performance it may be possible to evaluate if some behaviours are more desirable at the race track than others. The aim of this study was to see if behavioural responses correlated with physiological parameters (heart rate, cortisol), the trainer?s opinions and actual race performance.

Android is one of the leading software platforms for the new generation of smartphones. The market for applications is growing rapidly. So to be able to compete with such large competition the applications need a solid and stable development methodology. Therefore have we created an application based on a test-driven development, to investigate if the methodology was applicable on the Android platform. The conclusion is that Android?s suitability for test-driven development is dependent on the application that is being developed and if difficulties concerning the testing framework can be avoided.

The purpose of this thesis work is to create a prototype for an augmented reality application that isaimed to support service technician when performing service and maintenance of machines andengines. The prototype will be used for investigating what technical limitations there is and toestablish basic usability for the user interface. The method that is used is user studies and analysis toevaluate use cases and user stories. An iterative work process is then applied for design and theprototype is continuously user tested.The resulting prototype uses a Samsung Galaxy Tab 2 running on Android operating system. Theframework used for augmented reality is NyARToolkit which handles marker recognition andconnections to Android.

Randomness is a complex area of computer science, where only pseudo random numbers are possible to generate algorithmically.This report presents established algorithms for random number generation by conducting a basic study of relevant literature, while testing distribution and speed of the algorithms contained within the C++11 Random library. The results are compared to the algorithm XORShift and a modified version of it. The study shows that the modified algorithm passes all tests in Small Crush, andthat the run time is shorter than for those in the Random library. The conclusion is that it is possible to, with simple means, modify an algorithm to outperform the algorithms of the C++11 Random library..

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.

Det råder en ökad tendens för den svenska småspararen att diversifiera sin aktieportfölj efter eget behag så att andelen obligationer och aktier tillsammans med utländska värdepapper och derivat kan ge maximal avkastning i förhållande till risk. Ett förekommande problem är dock att hitta rättvisa mått, matematiska och ekonomiska, som visar den korrekta bilden av en tillgångs utveckling i förhållande till marknadsportföljen varpå det krävs en förståelse för hur en tillgång eller en portfölj rör sig rent matematiskt. Utvalda aktier och obligationer ska avläsas ur måtten kovarians, korrelation, effektivitet och volatilitet och sedan ska resultatet ställas mot att enbart ha analyserat betavärdet för portföljen för att komma fram till lämpliga matematiska uttryck när man analyserar den diversifierade aktie/obligationsportföljen för en person med begränsad finansiell kunskap. Risken med urholkad valuta i utländska aktietransaktioner samt två olika optionsstrategier kommer också att redovisas rent grafiskt i studien för att visa utökade avkastningsmöjligheter..

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.
