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.

Kan man minska bilåkandet i staden? : sett ur ett stadsplanerarperspektiv
The reason why this essay is written can be parted in two, whereas one would be the global trend of urbanization that occurs to this moment and forward, whereas the other would be the debate of how motorism has come to be an issue of sustainable management of our cities and our environment. In purpose to deliver a thorough understanding of how the car and its capacity has come to shape the society of today, and to emphasize the problems it´s brought, a historical survey has been made, followed by the report of problems to the society formed by the needs of the car, discussed in several environmental issues, such as jamming, noise and air pollution. This is followed by the discussion of potential solutions for how city planning could return to the focus of the human scale and perspective, in purpose to correspond with the issue of ways to decrease the car use in towns. In conclusion, the given solutions are discussed, where examples like shared space, investment in public transport, mobility management and the theory of the assembled city are included, with aid from literature, to finally conclude the essay with personal thoughts of how the planning of today, or the given solutions, really are the result of sustainability for city planning from a human perspective.

The mortgage limitation has both before and after the introduction been a topic of discussion as it affects many and above all makes it diffucult for certain customer groups.Method: This report was written by a qualitative method. The report uses qualitative and quantitative data. The quantitative data we have in the report are printed literature in books, articles and journals as well as data taken from Internet.
Cykelparkering i stadsmiljö : en redogörelse för cykelparkeringens komponenter
In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.
Utveckling av kombisåg
Denna rapport avhandlar det examensarbete som genomförts av Rua Dawood och Noor M. Yasin, vårterminen 2013 vid Mälardalens högskola. Rapporten redogör för den design- och funktionsmässiga utvecklingen av en såg, med hänsyn till det uppdragsgivande företagets sortiment och användares önskemål.Vår uppdragsgivare är EKA-knivar AB, som är ett ledande företag inom tillverkning av knivar och sågar i Sverige. Av EKA-knivar AB fick vi uppgiften att utveckla en såg som kan passa för användning ute i skogen och hemma. Problemet med dagens såg är att den har skarpa och vassa kanter och ett icke ergonomiskt handtag som ökar belastningen på handen och handleden vid arbete.
Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen
The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.
Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasin
Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasinHugo de Campos PereiraSyftet med detta arbete har varit att kartlägga vilka mekanismer som styr lösligheten av sällsynta jordartsmetaller (eng. rare earth elements, REE) i sulfidhaltig anrikningssand vid den föredetta gruvan Källfallsfältet i Västmanland. För syftet har markvatten- och grundvattenprovtagning utförts, tillsammans med laktester och geokemisk modellering med Visual MINTEQ ver. 3.0.Resultaten visade att sulfidvittring är den främsta processen som styr pH i anrikningssanden, och därmed också indirekt REEs löslighet. Däremot är sulfidvittring ingen källa till REE i sig då ämnena inte föreligger sulfidbundna, något som oxiderat tillgänglighetstest NT ENVIR 006 visade.
Jämförelse mellan sojaböna och åkerböna som proteinfoder till växande grisar
The soybean can be used in multiple ways, and its high oil content makes it suitable for extraction. Soy bean meal, a by-product of the oil extraction, is a good source of protein with a high feeding value, and is therefore used in a number of different animal feeds. Further, soy bean meal has a low production price, which is one of the reasons for the extensive export of the product. There is a great demand for vegetable-based proteins, especially in the organic production where synthetic amino acids are banned. However, the current production of soy beans is not environmentally sound and that combined with the long transport distances amplifies the need of finding a locally produced protein source.
Kompensering av reaktiv effekt vid vindkraftverk

RA Detect - Antikollisionsskydd förlantbrukssektorn
SecRePac is a household appliance that simplifies sorting of packaging such as milk, juice and yogurt containers. By shredding the packages SecRePac reduces its volume uptake both in the home and at the recycling station. This leads to minimization of both transports to the recycling stations and truck transport for emptying the containers at the recycling station.The greenhouse effect deteriorates and becomes worse and worse leading to extreme climate changes and natural disasters such as floods as an example. Carbon dioxide emissions are the major reason for this and at least 30 percent of all these emissions come directly from transports. In the EU carbon emissions has decreased in the past few years.
Kostnadseffektiv minskning av koldioxidutsläpp från tunga fordon i Sverige :
When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.
Förbättring av dockning mellan lastvagn och autoklav
At present Getinge can offer a new generation of trolleys that they produced in 2011. The trolley used to Getinge various autoclaves and has the primary task to help the user/sterilization personnel to transport shelves or baskets, with or without cargo, from a packing table to the autoclave. The purpose of this thesis has been to develop a primary solution how the docking process between Getinge trolleys and autoclaves can be improved. The work has in most part followed Fredy Olsson principle and primary construction method. The work has included product research, study visit and development of a requirements specification, to satisfy Getinge, their clients and circumvention products requirements.
Den psykosociala arbetsmiljön inom tillverkningsindustrin och transportbranschen
Psykosocial arbetsmiljö är ofta ett bortglömt redskap för företagare som vill vara konkurrenskraftiga på den globaliserade företagsmarknaden. I föreliggande studie undersöks den psykosociala arbetsmiljön hos två branscher, transport och tillverkningsindustrin i Jämtlands län. Mätinstrumentet som används är Rubenowitzs psykosociala arbetsmiljö-kartläggning enkät (PAK), som mäter fem faktorer: egenkontroll, stimulans från själva arbetet, arbetsledningsklimat, arbetsgemenskap och optimal arbetsbelastning. Studien undersöker sambandet mellan de fem faktorerna, ålder och branschtillhörighet. Analyser av de fem faktorerna visar att de har ett svagt till måttligt positivt samband med varandra.
Vad begränsar lärarens handlingsutrymme? : En studie byggd på samtalande lärare, analyserad med Gunnar Bergs teori som ram
In order to get a better understanding of the interaction between employees and their technical work tools one needs to know what factors influence the interaction. The purpose of this study was to examine if there is a correlation between the personality traits Extraversion (E) and Neuroticism (N), tested with Eysenck Personality Inventory (EPI), and experience of the new Intranet among employees at The Swedish National Transport Administration (SNTA), and also to gather information of employees? opinions about the new Intranet. A survey, containing questions about the Intranet and a personality test (EPI), was posted on SNTA?s Intranet for eight workdays (N = 88, females = 53, males = 35).
