Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler
This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.
Test och verifiering av en ny inkapslingsmetod för SiC BJT och MOSFET
The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..
En analys av testprocesser med TMap som testmetod
Today there are many system development projects that break both budget and time plan. Often this depends on defects in the information systems that could have been prevented. The cost of test can in some cases be as high as 50 % of the projects total cost and it's at the same time an important part of development. Test as such has moved its focus from the software it self and its faults to a wider perspective on whole infrastructures of information systems where assure a good quality is important. Sogeti in the Netherlands have developed a test method called TMap (Test Management approach) that can be used for structured testing of information systems.
Ideella drivkrafter, en studie av Rädda Barnen och Hungerprojektet
Civil society is facing many challenges in modern society and there is a lot of debate about where it is heading - is volunteer work declining or just taking a new form Whichever hypothesis will prove correct in the future, organizations that are dependent on volunteers will need to adapt to the new circumstances. This study aims to examine what forces drive voluntary work at Rädda Barnen (Save the Children Sweden) and Hungerprojektet (The Hunger Project Sweden). Through interviews with employees and volunteers at the two organizations, this study finds that volunteers at Rädda Barnen are primarily driven by values and understanding, and that the volunteers at Hungerprojektet are primarily driven by career and to some extent by values, enhancement and social factors. Understanding these driving forces allow the organizations to adapt to the new circumstances by matching the volunteers interests with the organizations' needs..
Repeterbarheten hos Schirmer I test
Syfte: Syftet med den här studien var att undersöka repeterbarheten hos Schirmer I test samt att undersöka om det fanns något samband mellan Schirmer I test och enkäten TERTC-DEQ.Metod: 26 personer deltog i studien. Innan första mättillfället fyllde försökspersonerna i ett informerat samtycke och enkäten TERTC-DEQ. De undersöktes med hjälp av ett biomokroskop och deras ögon graderades med hjälp av Efron och CCLRU grading scales innan första mättillfället. Schirmer I test mättes vid tre tillfällen med en veckas mellanrum.Resultat: Resultatet av mätningarna visade att det var låg repeterbarhet hos Schirmer I test om man utför tre upprepade mätningar. Resultatet visade också en korrelation mellan testresultaten och enkäten TERTC-DEQ (r=-0,6184), det vill säga de försökspersonerna som hade ett högt resultat på Schirmer I test hade också en låg summa på enkäten TERTC-DEQ.

Volatilitetsprognoser på den svenska aktiemarknaden: Tillämpning av Arch Typ modeller
This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.
Testdriven utveckling (TDD) ? En metod för att minska underhållskostnader i mjukvaruprojekt?
The maintenance phase within software projects is typically very expensive in terms of resources. The activities of this phase are largely focused around some form of modification of program code. This leads one to consider if there are alternative methods of code production that results in code that allows for less costly modifications. This thesis has its basis in a subset of those concepts which research has shown to provide more flexible code. Once this subset is established, connections are made between the concepts within the subset and claims of benefits provided by the use of Test Driven Development (TDD) methodology.

Fysprofilen hos puckelpiståkare på elitnivå och en jämförelse av fysisk prestation över tid
AimThe aim of the present study was to evaluate physical performance according to ?fysprofilen? in skiers of the Swedish mogul ski team and to compare their physical performance at three test occasions during one year.MethodsAll eight elite mogul skiers at the Swedish national mogul ski team during the seasons 2011/2012 and 2012/2013 participated voluntarily in this study. The test battery ?fysprofilen? was performed at three test occasions, October 2011, May 2012 and October 2012. Muscle strength was evaluated with squats, bench press and grip strength; power was evaluated with power clean, squat jump, countermovement jump with and without arm swing, Harre´s test and the 30 meters sprint.
Design and performance of Small scale sensory consumer tests
Small scale internal consumer tests provide a company with a cheap way to get valuable information regarding their products advantages and flaws. Therefore the demand for possibilities to do this kind of test has increased. This report is part of a new sensory project at Unilever. It presents a method for sensory comparison of the company?s own products with the corresponding competitor products.

Utvärdering av ett mikroalbuminuritest till hund :
The occurrence of small amounts of albumin in urine, microalbuminuria (MA), is used both in human- and veterinary medicine as an indicator for patients who have developing proteinuria. Proteinuria can be prerenal, renal or postrenal which is important to establish during an investigation. With conventional methods decreased renal function is not detected until 70 % of renal function is lost. The ability to detect and start a treatment earlier might reverse or slow the progression of disease.
The purpose of this study was to investigate the reliability of Heska® E.R.D.-Health Screen?, a test for microalbuminuria in dogs, to detect albuminuria.

En utvärderingsmodell för testverktyg : Med inriktning på automatiserade högnivåtester
Testing has always been an important task in the scope of software quality. Though it has never been as much appreciated within the management of the organisations as the software development has. However testing is becoming more attractive within organisations because it becomes more evident how much money working systems saves in contrast to defect ones. A tester often use testing tools to simplify the work progress. There are a lot of tools nowadays but not many evaluating models which helps the tester to know which one to recommend.
