Rostfritt stål som ett alternativt material till koppar i tappvattenledningar för bostäder

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Kylkedjan för snittblommor - en kartläggning av distributionen

Title:Chillchain for cut flowers ? how the distribution works.Author:Anna-Maja Svarén, student at Lund Institute of Technology, mechanical engineering.Supervisors:Annika Olsson, Department of Design Sciences.Bengt Sahlberg, Bioett AB.Problem:How does the distribution of cut flower works regarding temperature, losses, responsibility, complaints, packaging and weak points?Purpose:The purpose is to map the distribution of cut flowers, with focus on losses in the temperature, from farm to store. The goal is to identify weak points in the chillchain and to se how wrong temperatures affect the flowers. The results can be a help to secure the chillchain.Method:The work started with a problem; map the distribution of cut flowers with focus on temperature losses. Data was collected on the basis of this problem, then analysed, and finally conclusions were drawn.Conclusions:The affect handling and distribution has on a cut flower is very complex.

Processkartläggning samt förbättringsförslag vid Götene Stål & Verktygs AB

The purpose of this report is to come up with possible improvement suggestions to the distribution central at Götene Stål & Verktygs AB (GSV). GSV is a wholesale dealer located in Götene. The company doesn?t produce anything it self, it buys in products and sells them to customers.The distribution central at GSV is the place where the products comes in and gets ready to deliver.To come up with possible improvement suggestions we started with process mapping over the main process and the distribution centre process. The main process here is from the point where the customer gives GSV an order to the point where GSV deliver the order.Our result shows that the major problem in the distribution central at GSV is the big volume differences in the incoming goods.

Ska pyramiderna rivas?: en studie om mikromakt

It has been demonstrated in this study how people working in frontline jobs in service organizations are exercising ?micro power?. The use of ?micro power? is defined as ?to in ones professional role, without objectively defensible reasons, impose sanctions on a customer?. The interviewees are explaining their use of ?micro power? with mood, working conditions, and customers? behavior.

Det talas om utbrändhet : vilken roll spelar maktstrukturen

In this paper we investigate whether power structures in organizations have an influence in the process that leads to burnout. We analyze if these power structures affect the individual?s health condition toward burnout in a way that leads to disability and subsequent absence from work. In the study, six persons who all have been unable to work due to burnout have been studied through qualitative, semi-structured interviews. The material have been coded with three different themes; leadership and hierarchy, responsibility and delegation of responsibility and performance and loyalty.

Värmning av avloppsvatten med spillvärme för att förbättra kvävereningen -Temperaturens inverkan på kvävereningen

The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.

Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the Power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

Vetenskap och makt. En analys av två vetenskapliga paradigms skilda maktlogiker.

This essay analyse the relationships between scientific paradigms and different logics of power in the field of psychiatry, primarily in the fields of attention disorders of children and schizophrenia. In these two fields of psychiatric research and treatment, there exist two scientific paradigms, a biological/neuropsychiatric and a socialpsychological, working from different standpoints regarding questions of ontology, epistemology and theories of value. Drawing from Thomas Kuhns paradigmatic theory of science, and Michel Foucaults concept of power, this essay proposes that different paradigmatic standpoints gives rise to different logics of power. Relying on the concept of power/knowledge and different paradigmatic standpoints, the essay states that the biological/neuropsychiatric paradigm produces a biological individualising logic of power that fixes the individual to his/hers biological condition. This in contrast to the socialpsychological paradigm, which on the basis of its paradigmatic standpoints produces a social-group related logic of power.

Att tillgängliggöra distributionsstödda titlar med hjälp av marknadsföring ? En studie om bibliotekariers ansatser på området

The purpose of this master's thesis is to study how librarians at public libraries make the literature with state supported distribution available through marketing. By qualitative interviews with nine heads of libraries the thesis examines how the library staff in each library market the state supported distribution by the Swedish Art Council. My theoretical framework is based on Philip Kotler's thesis on marketing. My conclusion is that the library staff rather market the library as whole, than focus on just one specific type of books. The attitudes toward the state supported distribution are a mixed one, but the library staff is glad for what is given..

Digital speldistribution - Om behovet av rekommendationer och riktlinjer inom

Digital distribution för datorspel växer för varje år. Med tiden har fler och fler webbutikermed endast digitala produkter dykt upp, samtidigt som de gamla till en allt större del harbörjat erbjuda ett digitalt sortiment. Konsumenterna har med denna utveckling ett hav avolika typer av distributionsmöjligheter att välja bland. Vissa kan för en del konsumenterkännas restriktiva, medan andra webbutiker erbjuder en typ av försäljning som påminner merom den fysiska.Syftet med denna studie är att försöka identifiera de olika typer av affärsmodeller ochdistributioner som finns i dagsläget, och om det finns behov av att införa någon typ avstandard i form av riktlinjer och rekommendationer för digital distribution.Studien visar att det skulle vara problematiskt att tillämpa riktlinjer som skulle fungera ipraktiken för alla dessa varianter av digital distribution. Men samtidigt identifieras ett antalproblem som individuellt skulle kunna åtgärdas med hjälp av några av de riktlinjer ochrekommendationer som tas fram genom bland annat kvantitativ undersökning blandspelkonsumenter och intervju med Sveriges största aktör inom området..

Sjuksköterskans erfarenheter av att i palliativ vård arbeta enligt standardvårdplanen LCP

The purpose of this thesis is to identify power structures and instruments of power within the Jehovah?s witnesses and investigate how they affect the baptized youths baptized within the organization. The material consists of qualitative in-depth interviews and is analyzed with Foucault's theories of power. The results show that the participants have a very strict relationship to the rules of the congregation and also that they take great care in observing these rules carefully. It becomes evident that young members are exposed to disciplinary measures from the organization.

Power supply monitoring for wireless sensor platforms

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Hur ser lavars fördelning ut runt stammen på ek, och påverkas den av trädets storlek och dess närmiljö?

The aim of this study was to describe preferences of geographic direction of ten, oak-living epiphytic lichen species and how they responded to sun exposure, nearby bushes and trees, bark fissure depth and circumference. The frequency of every species was recorded in arcs of ten degrees around the tree at a height of 130 to 180 cm above the ground. An estimation of the amount of every species in every arc was also recorded. To analyse how the distribution of the lichen species responded to the different factors their concentration for every tree was plotted against the four factors. The distribution of Cliostomum corrugatum had a positive response to high sun exposure and a negative response to a thick layer of bushes and trees.

Mot mer makt? - En studie om utvecklingsländers maktsituation i Världshandelsorganisationen WTO

This thesis examines the power of developing countries within the World Trade Organization (WTO). The research question is if there is a change in the power relations between developing countries and developed countries from the establishment of the WTO in 1995 and until mid 2006, and if so, why this change is taking place? The thesis has its theoretical starting-point within regime theory and views it from a critical theoretical perspective. A multidimensional why of dealing with the concept of power is being used to answer if there is a change in the power relations? The conclusion is that there is a small change in the power relations and that the developing countries are gaining more, but limited power.
