Testmetodik för vintertestning av el- och hybridfordon
With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.
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.
Analys av parathormon och joniserat kalcium i blod hos hund :
The calcium homeostasis in the body is normally strict regulated to be kept within very narrow limits. This regulation is due to the action of parathyroid hormone (PTH) which is synthesized in the chief cells of the parathyroid glands. In different diseases, the calcium homeostasis is disturbed and this could either be due to a dysfunction of the parathyroid gland itself, or it could have a completely different explanation. To investigate disturbed calciumhomeostasis, ionized calcium and PTH can be analyzed from a blood sample. There are a lot of different assays to measure PTH in humans.
Pojkars och flickors brinnande intressen : En analys av 10 elevtexter ur ett genusperspektiv
The main purpose of this study is to analyze texts written by pupils during the national test in the subject Swedish for grade 9 in order to identify and illustrate how they have met the instructions for the writing task including genre. The texts have been analyzed using Palmér & Östlund-Stjärnegårdh?s (2005) model for student text analysis. This model has been supplemented by studying word and sentence length, as well as indexes for level of readability (LIX) and word variation (OVIX) in order to illustrate possible differences in a gender perspective. The results of this study are in line with previous research, as the girls? texts are longer and more descriptive, while the boys? texts are shorter and show a wider range of word variation.
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.
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.
Wicking ? Utvärdering av två standarder
Syftet med rapporten är att utvärdera och jämföra två standarder, AATCC Test method 198-2011: Horizontal Wicking of Textiles och AATCC Test method 197-2011: Vertical Wicking of Textiles. Standarderna publicerades år 2011 av American Association of Textile Chemists and Colorists. Standarderna mäter wicking, det vill säga, med vilken hastighet som vätska transporteras genom textil, med en horisontell och en vertikal testmetod. Hastigheten anges i olika enheter beroende på standard, enheten för AATCC Test method 197-2011: Vertical Wicking of Textiles är mm/s och AATCC Test method 198-2011: Horizontal Wicking of Textiles anges i mm2/s. Skillnaden i enhet och mätmetod innebär att standarderna inte kan jämföras rakt av genom resultat och mätvärden mellan de båda standarderna.
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.
Alarmerande eller förväntat? : En studie av hur ett screeningtest kan tolkas ur ett andraspråksperspektiv
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.
Tensor representation of 3D structures
This is a thesis written for a master's degree at the Computer Vision Laboratory, University of Linköping. An abstract outer product is defined and used as a bridge to reach 2:nd and 4:th order tensors. Some applications of these in geometric analysis of range data are discussed and illustrated. In idealized setups, simple geometric objects, like spheres or polygons, are successfully detected. Finally, the generalization to n:th order tensors for storing and analysing geometric information is discussed..
En undersökning om typografins betydelse för läsbarhet av ord i rörelse
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.
