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.

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.

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.

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.

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.

The aim of this thesis is to get a better understanding of how the management control system works at V&S Distillers. V&S Distillers went through an organizational change in the beginning of 2005. The marketing function went from being a country-driven to a category-driven organization. Among other things this resulted in increased cooperation between employees in different geographical locations. We aim to analyze how a geographical distance affects relations and the use of management control.

AbstractThe purpose of this paper is to investigate to what extent LS ? a standard screening test for dyslexia ?is also relevant for the purpose of finding second language students with dyslexia. Starting with an overview of recent studies in the field, I have analyzed texts from parts of the chosen material. After a brief presentation of the test, I have presented it from a second language point of view. Furthermore, I have analyzed the way in which the test measures phonological awareness, lexical accessibility and correctness in language.

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

SAMMANFATTNING Läkemedelsresistens är ett växande globalt problem. Inte minst bland parasiter hos våra djur har rapporter om utebliven effekt av läkemedel ökat. Pålitliga detektionsmetoder av anthelmintikaresistens hos nematoder är viktig så att åtgärder sätts in i ett tidigt skede för att djurvälfärd och produktion ej försämras. Detta kräver standardiserade och beprövade detektionsmetoder. De metoder som används idag för flertalet nematoder är ursprungligen framtagna och anpassade för strongylider hos får.

The purpose of this work was to determine how important a word?s setting was for the readability of typography in motion. Facts regarding how reading works and the importance of the words formation for the readability were used to form a computer test. This test was performed by 15 test persons and the results were analyzed. The results show that the serif was easier to read than the sanserif.

According to recent research the basics for a good body posture is balance between the muscles, if unbalance originates this can be strengthen by gymnastics when most of the practise performs only in one direction. Because of limited research in the area was an explorative study conducted. The purpose of the study was to inquire if exercise adjusted to the individual contributes for balanced muscles and if it contributes for a positive or negative development for the team.On the basics of that the team is not equable an other team in the area has the results for two different periods been measured, during the first period the exercise continued as usual but during the second period each gymnast (n=9) received an individual strength- and stretch program that was performed during the teampractise twice a week. The gymnasts were tested in areas that are imported for them as body posture, balance between the muscles, vigour, range of movement, balance, the running and coordination. The results showed on that the difference is largest between test two and three, except the coordination and balance which did not show any particular change.

This essay is about the question if there is any difference in quality at the homes for the elderly in Skåne, depending on however the home is run by a public organization or private counterpart. The quality of the homes is meet with the help of numbers in ?the guide for the elderly? the facts in the guide are collected and judged by the ?Swedish National Board of Health. The result from the guide is divided into seven areas of quality, and then compared in a statistic test between the different types of organizations. And finally the result of the statistics is put in the context of the theory of New Public Management.

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

The current paper compares the relations between different measures of activity and some common neuropsychological tests. One-hundred and fifty five healthy elderly, aged 55 - 85, living in Sweden were included. Gender-specific patterns were found for both activities and correlations between activities and cognitive measures. The main findings suggest that activities are associated with cognitive speed in men, whereas, for women, active and passive activities correlate, positively and negatively accordingly, with education. In comparison, complex models of activity outperform simpler ones and theory-driven measures just barely outperform intuitive models..
