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.
PRAKTISK BESTÄMNING AV KLÄMKRAFT OCH FRIKTION I SKRUVFÖRBAND
This report reflects an examination work performed for Getrag All Wheel Drive AB during the spring of 2005. Among the companies range of products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque.The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for clamping force and friction through utilization of existing testing equipment.Three separate methods of clamping force and friction determination have been tested in rear drive unit, RDU, at a 30 Nm assembly torque. A fourth and final method, screw elongation with ultrasound, has been used as reference. The methods are:?Torque-Tension test.?Screw elongation with micrometer.?Joint stiffness test.?Screw elongation with ultra sound for reference.The results from tests can be viewed in table below.MethodTorque-TensionMicrometerCs=318 kN/mm Assembled with torque wrenchMicrometerCs=318 kN/mm Assembled on lineUltra-soundCS=311 kN/mm Ultra- soundCS=318 kN/mm Joint stiffnessTheoreticalClamping force-21,8 kN17,6 kN17,3 kN17,6 kN17,1 kN17,3 kNFriction-0,110,1470,1530,1470,1520,149.
COMPARATIVE STUDY OF HYDROLYSIS PERFORMED WITH MODERN MICROWAVE TECHNIQUE AND THE TRADITIONAL METHOD
Proteins are vital to all cells in the body. They consist of long chains of amino acids. To be able to study the amino acid composition of a protein it is necessary to hydrolyse it, followed by separation and quantification. When the protein is hydrolysed, in this case ß-lactoglobulin, the protein is divided into individual amino acids. The method that traditionally has been used to hydrolyse proteins takes 24-72 hours to complete.
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.
Mental träning på schemat : Hör tankens kraft hemma i skolan?
AimThe aim with this study was to acquire knowledge of mental training and if you can use it in the elementary school to increase in a short period of time the performance in a coordination test. Furthermore we wanted to investigate teachers understanding of the possibilities to perform this kind of training in the elementary school, and if there is support for this in the school regulation.MethodAs method we have used a combination of a literature pre-study, interview and at the end an experiment. Before the experiment and interviews could take place we studied literature about mental training to get a basic knowledge of the subject. The facts we learned from our pre-study and interviews gave us the base for our experiment. The experiment group included 23 pupils in a third class at school situated in Stockholm.
Utvärdering av mätmetoder för att fastställa lackmängden vid offsettryckning on-line

The aim with the project is to investigate if any Test method correlateswith the quantity of varnish and to improve the understanding of the variables in the varnishingunit. The goal with the project is to develop a functional method. Two printing trials have beenperformed.
Trombocyträkning hos katt : en ny metod
Platelet aggregation is a major and common problem in blood samples from cats. This greatly affects the accuracy of counting of the platelets. Because of the difficulties in counting feline platelets, results for patients and reliable reference values for cat platelets are currently so inaccurate as to be almost useless in diagnosis of thrombocytopenia. In this study we used an effective method to prevent platelet aggregation. Blood was collected in CTAD test tubes and prostaglandin E1 was added to the blood sample.
Förbättring av den svenska kiselalgsmetoden-hantering av sedimentering
Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water.
The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water.
First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.

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.
Utvärdering av ett auditivt diskriminationstest på 3-åriga barn
A speech-based material that early can assess a child's hearing is needed to provide an indication of a hearing impaired child's language development. Being able to identify and discriminate between different sounds is a requirement for interpreting speech. Hearing assessments that examine speech perception can therefore, unlike, for example, pure tone audiometry, examine a hearing impaired child's perceptual language skills and provide a basis for intervention.The purpose of this work is to evaluate a new auditory material on 3-year-old children. The auditory material is based on the Ling-6-sounds and the main question was which of the sounds in the test were adequate for test of discrimination. Furthermore, it was investigated how the test works with children aged 3:0?3:11 years and how age and gender affect the result.Twenty-four children aged 3:0?3:11 years were tested using a computer based test.
