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.

Vi har gjort en kvantitativ studie som avser att kartlägga produktionsarbetares upplevelser av faktorer kan påverka hälsan. Dessa faktorer har vi delat in i fyra rubriker som genomsyrar hela uppsatsen, de är Delaktighet, Feedback, Arbetsmiljö och Lärandet. Data samlades in genom att enkäter som lämnades ut till 97 produktionsarbetare på två olika företag. I resultatet belyses personalens åsikter och upplevelser om feedback, delaktighet, arbetsmiljö och lärande och hur det påverkar dem i arbetet. Slutsatser som kan dras är att respondenterna i vår undersökning mår bra men de skulle få ännu bättre hälsa om de kände mer delaktighet och om de skulle få feedback när de gjort bra ifrån sig.

The overarching purpose is to describe how elite soccer clubs choose to structure their sport oriented organization. This purpose leads us to questions and areas involving sport managers, casting, operational directions, education and goal setting in sport.The results in this thesis are based upon a qualitative investigation of sport managers in Swedish elite soccer clubs. To strengthen the reliability in our choice of method we will fortify it with theories that reflect methodical choice.Our conclusions in this thesis is that one can see a clear difference in how the clubs choose to structure the casting and operational directions within their organization. We have also noted that there is a clear distinguish between the levels of education amongst sport managers in Swedish elite soccer clubs..

Göteborg Energi AB är ett bolag med höga ambitioner att säkerställa ett stabilt distributionsnät för sina kunder. Med ett säkerställande följer åtgärder i form av beräkningar för komponenter som transformatorer av olika märkeffekt, hög- och lågspänningssäkringar och andra kritiska skyddsanordningar som t.ex. reläskydd. Vid ett flertal tillfällen under de senaste åren har det uppmärksammats en problematik där ett fel i lågspänningsnätet har löst ut anslutande transformator. Felet har grundat sig en svag selektivitet mellan transformatorsäkring och lågspänningssäkring.

Syfte och frågeställningarSyftet med denna studie är att undersöka lärares uppfattningar och föreställningar om bedömningsredskap och strategier, i synnerhet feedback samt hur lärare skapar förståelse för förväntade lärandemål och framgångskriterier.- Hur arbetar lärarna med att skapa förståelse för förväntade lärandemål samt hur förmedlar de framgångskriterier till eleverna?- Hur arbetar lärarna med feedback i sin undervisning?MetodStudien är grundad på kvalitativ metod som datainsamlingsmetod och min studie kommer därför att baseras på kvalitativa intervjuer. Urvalet bestod av fem idrottslärare verksamma på grundskolor i Stockholm med omnejd. Intervjuerna genomfördes på respektive lärares arbetsplats och spelades in med hjälp ljudupptagning från en mobiltelefon. Därefter transkriberades intervjuerna ordagrant för vidare analys.Resultat och slutsatsStudien visar att inte alla lärare arbetar med att skapa förståelse för förväntade lärandemål samt att förmedlandet av lärandemål sker i mindre eller större utsträckning beroende på årskurser och moment.

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

The Swedish field of digital X-ray imaging has since several years relied heavily on distributed information systems and digital storage containers. To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback?the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.

Syftet med den här uppsatsen var att belysa hur ledningen i bemanningsföretag ger stöd till anställda genom feedback. Uppsatsen börjar med att vi tydliggör ett praktiskt problem som är vanligt förekommande inom bemanningsföretag. Vi illustrerar detta problem med en figur som åskådliggör en distans mellan bemanningsföretagen och dess anställda. Den här distansen kan emellertid leda till bristfällig kommunikation mellan parterna och för att minska sannolikheten att detta uppstår, kan ledaren i ett företag stödja de anställda genom att ge feedback. I teorikapitlet utgår vi från en modell som visar de faktorer som bör beaktas, det vill säga 360-gradersfeedback, coachning, uppmuntran till dialog, självkontroll samt lärande organisation.

I denna studie undersöktes hur feedback påverkar tillförlitligheten i äldre ögonvittnens konfidens- och frekvensbedömningar, d.v.s. realismen i deras vittnesmål. Detta skedde genom ett experiment med 35 deltagare som vid ett tillfälle fick se ett kort händelseförlopp på film. Deltagarna delades sedan in i två grupper (experimentgrupp och kontrollgrupp) och fick vid ett andra tillfälle fylla i ett frågeformulär med 42 frågor rörande händelseförloppet. Experimentgruppen erhöll två typer av feedback (stödjande och icke-stödjande), som var konstruerad information om vad en annan deltagare hade svarat.Vid bedömningen av enskilda frågor visade båda grupperna överkonfidens, men experimentgruppen visade högre överkonfidens vid stödjande feedback än vid icke-stödjande feedback.
