SSD - Stair Support Device
Together with Hälsoteknikalliansen the project team recognized the need to improve availability in the staircase environments. This is a difficult environment, especially for our elderly. The staircase leading to and from apartments is such a major obstacle that many people do not dare to go into the staircase leading to their front door. The market study that the project team conducted showed that many were in need of a living support, often a relative, who helped and supported them when they went into these stairs. It also appeared that these people manage everyday life just fine, but they suffer the problems that stairs to and from their apartment causes.
Utvärdering och jämförelse av olika fälttester för fotbollsspelare
Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Automatiserad unit testning
Dagens utveckling av mjukvara går snabbare och snabbare
samtidigt som mjukvaran blir allt mer komplex. Att under dessa
omständigheter kunna bibehålla en lika om inte högre kodkvalité
är en utmaning. På UIQ bestämde de sig för att undersöka om ett
automatiserat unit test kunde hjälpa dem.
Metoderna för att komma fram till resultaten i denna rapport har
varit intervjuer, en enkät, intern information och litteratur så som
forskningsartiklar m.m.
Denna rapport är en utredning av automatiserade test, vad man
bör tänka på, vilka fördelarna är, vilka testfall som är möjliga att
automatisera med mera. Rapporten kommer även att presentera
grunderna i testning av mjukvara, en introduktion till eXtreme
Programming och Test-Driven Development samt hur testningen
utförs på UIQ idag.
Då jag kom fram till att ett automatiserat unit test skulle passa sig
bra på UIQ kommer jag i slutet av denna rapport presentera ett
implementerings förslag. Man bör även införa en test driven
utvecklings metodik för att säkerhetsställa att det kommer att
utvecklas automatiserade testfall..
Mätning av Mikroläckage i Dentala Implantat
Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss.
The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.
Yrkeselevers svenskkunskaper 1977 och 2014 : En studie av två elevgruppers resultat på ett centralprov
The aim of this study is to investigate how the Swedish language proficiency of pupils in vocational programmes in 1977 was measured and assessed with the aid of a national achievement test, and to investigate whether vocational pupils today, in 2014, have similar language proficiency to that of pupils in the 1970s. The study also discusses how the design of the national achievement test from 1977 reflects the view of knowledge that prevailed in society and in the policy documents. The material for the study consists of a total of 75 national achievement tests, 40 of which were taken by pupils on a vocational programme in 1977 and 35 by pupils on a vocational programme in 2014. The national achievement test consists of two parts, the first of which focuses on isolated elements of language proficiency, while the second involves free text production. The material was analysed quantitatively in accordance with the correction material from 1977.
Att förebygga hot och våld mot socialsekreterare
The aim of the study was to examine if and how the social service and the social welfare secretary provides against threat and violence in the encounter with clients. The study is qualitative and carried out with six semi-structured interviews with social welfare secretaries and participation observations at the social welfare offices in three municipalities. The theoretical starting points used were symbolic interactionism and strange loops. The result shows that social service and social welfare secretaries both use measures to prevent threat and violence to occur. The precautionary measures mainly used by social services are ; looked doors, alarm device, loose objects removes and interview rooms are furnish in purpose for the social welfare secretary to flee the room at urgent need.

Läsförståelse hos svenska gymnasieelever : En undersökning av hur gymnasieelever som läst svenska B respektive svenska som andraspråk B klarar TISUS-testets läsförståelsedel
AbstractThis paper aims to examine reading comprehension among Swedish Upper Secondary Schoolstudents who are doing their last school year. My research questions are if the students havesufficient reading comprehension to cope with university studies and higher educationaccording to a comprehension test and if there is a difference between students who studiedSwedish B course or Swedish as a second language B course. Furthermore it involves issuesof differences in results depending on gender and if the second-language students were bornin Sweden or abroad.To get answers to my questions, I let 112 students in my survey carry out the readingcomprehension part of the TISUS test, observed several test sessions, and interviewed 24students who participated in the test. The result shows that most students have difficultieswith the reading comprehension, and probably would find it difficult to study at universitiesor colleges. There are major differences in the results between the Swedish B-students andSwedish as a second language students, but also within these groupings.
Att utföra kravprioritering med kravprioriteringsmetoder - en studie om dess genomförande och hinder under
Prioritisation of software requirements is a critical part of the development of software. Whichrequirements and in which order they will be developed is one of the main tasks that requirementprioritisation supports.There are different ways that a requirement prioritisation can be used, for example alone or in agroup and with different methods.The purpose of this report is to map out how you can carry out a requirement prioritisation alonewith different types of prioritisation methods and how you solve the problems that can arise whenprioritisting requirements. This is done by documenting the use of three different types of methodsthat can be execute alone. The methods are "100-dollar test", "Ranking" and "Top-tenrequirements".To be able to prioritise requirements, you need to establish which requirements you shall prioritise.The paper retrieves this information by interviewing stakeholders in the system and analysing theresult of the interviews and the execution of the requirement prioritisation.Three problems arose during that work and I present solutions on these problems. The problemswere 1) equivalent requirements when using the "100-dollar test", 2) low differentiation gradebetween the prioritised requirements in the "100-dollar test" and 3) that the requirements that wereprioritised weren't classified before the prioritisation, which leads to inaccuracies in the resultingprioritisation.The solution to the problems that the paper presents is to increase the amount of distributable unitsin the "100-dollar test" to 1000 per requirement, suggestions of classes of the requirements andthe combination of the methods "100-dollar test" and "ranking" to bypass the equivalentrequirements.The report is written in Swedish.Nyckelord: GoTRIS, requirements retrieval, requirements analysis, Viktoria Swedish ICT,requirements prioritisation, requirements, 100-dollar test, ranking, top 10 requirements..
Mätning av partikelmassa i avgaser från en dieselmotor
This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.
Betydelsen av verbal uppmuntran vid utförande av handstyrketest
The purpose of this study was to evaluate if verbal encouragement had any influence on handstrength measurements. Twenty subjects participated in the study, all women between the age of 20 and 62 years. A standardisation of testing conditions and verbal encouragement were designed. Three measurements were conducted during two days using T.K.K 5401 Grip D. First there was a trial set, and then Test 1 (without verbal encouragement) and Test 2 (with verbal encouragement) were conducted.
Deterministisk Komprimering/Dekomprimering av Testvektorer med Hjälp av en Inbyggd Processor och Faxkodning
Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

Viral Facebook integration i mobilspelet Gravel
This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.
