On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Infastrukturen och Klimatförändringarna : Hur klimatförändringarna kan påverka Kalmar
I denna uppsats har jag tagit reda på hur klimatförändringarna i framtiden kan komma att drabba Kalmar. Syftet med uppsatsen var att förklara för läsarna hur klimatförändringarna visar sig, hur de kan påverka städer och dessutom se hur de olika organisationerna som agerar inom kommunen och länet har planerat för detta och vilka kunskaper de har. Uppsatsen är skriven med en kvalitativ explanativ metod. Med hjälp av olika personer som jobbar inom berörda organisationer har jag kommit fram till att det största problemet som kan uppstå på grund av klimatförändringarna är översvämningar och stormar. Då Kalmar är en gammal stad som är uppbyggd nästan precis i strandkanten så skulle en permanent höjning av vattennivån medföra att stora områden i Kalmars centrala delar skulle kunna hamna under vatten.
Är företagets lönsamhet och finansiella ställning avgörande för beslut beträffande företagets expansion?
Even if the main purpose is to decide if the companies profitability and financial position is a determining factor for its growth, the purpose is to determine if there are any differences between big and small companies in there economical positions then they grow, in the selected industry. This thesis is mainly a quantitative study. The selected industry for the study is extraction of turf. The financial measurement that most clearly differ the growing companies from the not growing companies or the companies that didn?t change there amount of employees was the returns of the companies own capital.
Den Gropkeramiska kulturens framträdande : en kritisk analys gällande tre av de främsta teorierna kring den Gropkeramiska kulturens framträdande i Nordeuropa
In this essay the author has chosen to analyze the similarities and differences between some of the northern Europe?s late Mesolithic and Neolithic cultures. The research is of a processual standpoint and the information is mainly gathered from secondary sources as well as ethnological studies. The material collected has been analyzed in both a processual and a post-processual manner to most accurately study the foundations of the three primary theories describing the Pitted Ware Culture?s origin.
Påverkan mellan ekonomistyrningen och inköpsfunktionen : En studie av Sandvik och Scania
AbstractTitle:The Impact of Management Control Systems on the Purchaser Function - A study of Scania and Sandvik Authors: Mohammad Reza Akhbari and Johanna Sullivan Svensson Published: 2011 Keywords: Management control, purchasing function, impact, control, control instruments, Key Performance Indicators, measurement, communication and organizational structure. Background and problem formulation: In order for a company?s business idea or vision to be fulfilled, the management of a company needs assistance from various means to intentionally affect the operation in the desired direction. Management control concerns activities of both financial and non-financial character in order to implement the strategy of a company and to reach profitability. Since the purchaser function is responsible of spending 50 percent of a company?s total revenue, the function has an optimal starting point to be a key actor in the shaping and execution of a company?s strategic plan.
Det medeltida Visby : en kritisk studie av disskusionen om stadens etablering
Visby is a city that at first glance is of medieval origins. The popular image of scientists today is that the city was formed in the Middle Ages. According to some of the researchers Visby was formed during the Viking Age, it is based on the basis that the area has been used for a long period. Urban development in the Nordic countries is complex and there are different opinions as to why the Nordic cities emerge. It is important to shed light on the underlying process on why cities are emerging to provide clarity as to why Visby city is emerging.
DSP-baserat instrument för fjärrmätning av larmnät
Fält Elektronik AB i Kalix utvecklar och tillverkar bland annat larmsändare för fast uppkopplade larmnät. Fast uppkopplade larmnät används för att åstadkomma övervakad och säker överföring av larm och annan information mellan tekniska system för skydd och säkerhet. Larmöverföringen är ständigt övervakad från larmanläggningen ända fram till larmcentralen. Ett problem som idag finns i larmnät är att om man tappar kontakten med en larmsändare så vet man bara att man tappat kontakten, men inte varför. Därför vill man nu utveckla ett instrument som kan mäta och kontrollera vad som orsakar att uppkopplingen bryts t.ex.
Kognitiva processer i fingeravtryckstolkning : Hur tänkter experter och noviser
Forensiska tekniker såsom fingeravtryckstolkning har under senare år genomgått stora förändringar vad gäller exempelvis tekniska hjälpmedel, dock är människans roll i tolkningen fortfarande central i processen. Denna studie syftar till att öka kunskaperna om individernas kognitiva processer i tolkning av fingeravtryck genom ett experiment där fingeravtrycksforensiker, forensiker från andra fält än fingeravtryck samt noviser fick avgöra huruvida ett antal fingeravtryck härrörde från samma finger eller ej. De kognitiva processerna studerades utifrån att testpersonerna fick rapportera sin tankar verbalt i form av att ?tänka-högt?. Resultaten transkriberades och analyserades sedan med mixade metoder (mixed methods), det vill säga med både kvantitativ och kvalitativ metod. Resultatet visar att fingeravtrycksforensiker signifikant bättre kan lösa denna typ av problem jämfört med övriga forensiker och noviser, men att det fortfarande finns kognitiva processer hos fingeravtrycksforesnikerna som medför risker i form av bias i förfarandeprocessen..
Webbplatsen EUROPA: en utvärdering av söktjänsten
The purpose of this thesis is to evaluate the retrieval effectiveness on the European Unions official website EUROPA, depending on which language is used to formulate the search question. Our main concern were if you get access to the same information depending on which language is used to search information The European Union has so far eleven official languages, and with the forthcoming expansion with negotiations with thirteen new countries to affiliate to the union by May 1:st 2004, the official languages will be even more. We have made a comparison between Swedish and English, using 29 different topics from which we formulated 2x29 queries. The topics used were found at the Swedish Governments FAQ about the European Union, EUsvar. We wanted the topics to be as authentic as possible to avoid bias.

Utveckling av dataanalysprogram för Opcon Powerbox
Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.
Är företagets lönsamhet och finansiella ställning avgörande för beslut beträffande företagets expansion?
Even if the main purpose is to decide if the companies profitability and
financial position is a determining factor for its growth, the purpose is to
determine if there are any differences between big and small companies in there
economical positions then they grow, in the selected industry.
This thesis is mainly a quantitative study. The selected industry for the study
is extraction of turf.
The financial measurement that most clearly differ the growing companies from
the not growing companies or the companies that didn?t change there amount of
employees was the returns of the companies own capital. It was also the returns
of the companies own capital there the main difference existed between the big
and the small companies.
Dans som utställningsobjekt : Upplevelser och erfarenheter av tid och rörele i Dansmuseets permanenta utställning
This essay concerns dance as an exhibition object by examining the permanent exhibition at The Museum of Dance in Stockholm, Dansmuseet. Due to its dependence on the temporality and movement of the lived body, dance does not easily lend itself to being exhibited in a traditional exhibition display; and since the live dance performance itself is ostensibly absent at the exhibition display, other means of representation must be relied upon in order to evoke the exhibition visitors? experiences of time and movement as well as the feeling of dance. Starting from a phenomenological first-person perspective, as an exhibition visitor, I present three ways in which such experiences may come about. The cross-section of the experience evoked and the means that trigger them are intermedial, spatial, and performative taking their departure in the visitor?s pre-understanding of dance..
