Utveckling av provmetodik för HVAC på lastbil : Klimatprovning i klimatvindtunneln CD7
The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

Funktionell test på hundar med artros
The field rehabilitation in veterinary medicine has expanded over the past ten years. Animalswith disorders in the musculoskeletal system are often treated. The methods used lacksufficient scientific documentation; however claim to affect the animal's function in a positiveway. In order to investigate the efficacy of different rehabilitation modalities, it is important touse validated evaluation tolls. Therefore, a literature study on pain, pain-scales and functionaltest was performed together a pilot study on a functional test.The aim of the present pilot-study was to investigate a functional test, "Bioarth functionalevaluation scale", used in veterinary medicine.
Framtagning av en remdriven växellåda till en häcksax
The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.
Simulation driven design : An iterative approach for mechanical engineerswith focus on mesh, quality and convergence
This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.
Design av interaktionsmoment för spelarmotivation
The game industry is growing by every year but for some reason the research surrounding it hasn't caught up with its rapid expansion. This study aims at expanding the knowledge surrounding one of those areas, player motivations. An empirical model has been used to identify which interaction has the highest impact on player motivation in story-driven roleplaying-games. By conducting semi-structured interviews with eight different game developers using the GameFlow model to explore the use of interactions to sustain the motivation of the player a new criteria has been identified. This additional criteria was: Alive, and it was shown to have a high impact on motivation in story-driven roleplaying-games.
Emotionell kompetens : om möjligheter till utveckling och betydelse för ett effektivt ledarskap
Purpose of the study was to illustrate how emotional competence can be important for leadership and to explore the possibility of improving emotion perception ability after training. Participants in this study were 40 managers, divided into control and experimental group, within public administration. The participants implemented a data-based emotion perception test, which were done twice at every occasion, with intervention consisting of information or education between test- and retest. The result showed a clear improvement after intervention, in which no difference was found between control and experimental group, which has been discussed on the basis of the likelihood of a training effect occurred between test-retest. Conclusions about emotional competence or leadership ability could not be drawn from the results of the emotion perception test.
Drivaxeltrycksreglering hos tunga fordon : För en ökad framkomlighet vid vinterförhållanden
Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.
Att arbeta tematiskt, ämnesintegrerat-fördel eller nackdel-sett ur ett lärarperspektiv
Examensarbetet behandlar en jämförelse av Server Message Block 3.0 och föregångaren 2.1 i ett befintligt nätverk. Jämförelsen utfördes i fyra laborationsmiljöer bestående av fyra operativsystem: Windows Server 2008 R2, Windows Server 2012, Windows 7 ochWindows 8. Sammanlagt har fyra tester utförts: Förstudie, Test 1, Test 2 och Test 3. Förstudien utfördes för att testa nätverksprestanda mellan två datorer. De andra testerna satte SMB 2.1 och SMB 3.0 på prov.I Test 1 ansågs SMB 3.0 prestera sämre än SMB 2.1, för att bekräfta resultaten kontaktades Jose Barreto på Microsoft.
Arbetspsykologisk testning : Vad mäter ett situationsbaserat bedömningstest?
Tidigare forskning har varit oenig gällande vad ett SJT (situational judgment test) mäter. Studiens syfte är att undersöka vad SJT mäter genom att korrelera SJT-poängen med poängen på personlighets- respektive begåvningstest. Ytterligare en frågeställning är huruvida SJT skulle kunna vara ett användbart komplement till övriga arbetspsykologiska test. Totalt genomförde 130 personer fyra olika test; ett SJT, ett personlighetstest samt två begåvningstest (ett logiskt och ett matematiskt test). Resultatet av en regressionsanalys, med poängen på conscientiousness, agreeableness och g-faktorn som prediktorer av SJT-poäng, gav R = .31 och Adj R2 = .07.
Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.
Matematisk kreativitet
Syftet med denna studie var att undersöka hur man kan mäta matematisk kreativitet på olika sätt och att jämföra den matematiska kreativiteten mellan olika åldrar och mellan könen. 142 elever från åk 6, åk 8 och åk 1 i gymnasiet gjorde två test, test A och test B. Resultaten från test A visade att eleverna i stor omfattning saknar den kreativitet som behövs för att inte fortsätta att använda samma strategi när den inte är optimal längre. I detta test visade pojkarna bättre resultat än flickorna. När det i test B gällde att komma på många rätta lösningar var det deltagarna från åk 8 som visade större kreativitet än de övriga deltagarna i detta test.
