Electrical track system : Utveckling av ett nytt system, innefattande elektrisk golvlist och uttag, som medger flytt av de traditionellt fasta vägguttagen
This degree project concludes the Innovation and Design Engineering programme at Karlstad University. The project was carried out by David Brocker, Erik Hallberg and Andreas Hertzman during the spring of 2006 and corresponded to 15 weeks of work per student. Assigner was Martin Larsson at Arexor and instructor at Karlstad University was Monica Jakobsson.Arexor has a patent to a construction of an electrical skirting board with moveable wall sockets, called Electrical Track System. The lowest parts of the interior walls along the floor are today almost always covered by a conventional skirting board. Arexors patented product replaces that with the possibility to move and increase the number of wall sockets by choice along an electrical skirting board.
Lärk eller Impregnerat ? en kvalitativt jämförande livscykelanalys av sibirisk lärk och svensk tryckimpregnerad furu
This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Teknik för biogasanvändning
This thesis is made by Carl Persson and Alejandro Saavedra for Gryaab. Gryaab is Gothenburg?s water processing plant and produces about 60 GWh biogas annually with a flow around 1150 Nm3/h. Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.
Visualiseringsverktyg för Sykedjor
This thesis has been done in order to ease the process of drawing schematics ofelectrical wiring. The need arose after demand from the government due to a seriesof incidents that took place during the revision of the nuclear power plant in year2009.The task of the project has been to create a computer program that can generate agraphical representation of the electrical components relations. The basis for theprogram has been an example of how the client wants the graphical representation tolook. During the course of the project weekly meetings have occured in which theclient has reviewed the work.The result of the project is a program written in Visual Basic Applications that can berun in Microsoft Excel. The program is capable of generating graphics for a majority ofthe cases.
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.

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.
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.

Egenskaper och kvalitetsaspekter hos kött från mjölkrasgetter
Most of the goats in the world exist in the developing countries where they are important in the meat industry. In Europe, goats are mostly kept for milk production although the interest for meat is growing. Goats have a thin carcass with only small amounts of intramuscular fat, which gives a lean meat. This thin subcutaneous fat cover can cause cold shortening when chilling the carcass. By using electrical stimulation cold shortening can be prevented.
