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.

The study focus is partly on the relationship between the law, family and society. The main questions have been: Which one of the parents, mother or father, did in fact get the custody and why? How has the children?s point of view been reported in the inquiry? A child needs a well organized everyday life in a preferably conflict free environment.

Optimering av antenndesign utifrån experimentella data

During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.

Senkaku-Diaoyu ekonomin kontra militären : En kvalitativ textanalys om ö-konflikten mellan Kina och Japan.

The relationship between China and Japan has historically been problematic and, in some ways still is. One of the issues where both of the states cannot agree on is the island dispute. While both states are claiming sovereignty over the island and there do not seem to be an ending to it in the near future. If the island dispute continues to escalate it could have a negative impact in the Asian region and eventually rest of the world as well. However due to the complexity of the dispute a deeper knowledge is needed and a mutual understanding is needed.

Effektiviseringspotential inom projekt

The work is performed at Forsmark Group AB as a final step in the Bachelor ofScience program in nuclear engineering at the University of Uppsala in 2013.The work is part of an ongoing process of streamlining project system model FKA.Streamlining the project model is an important aspect that affects all largecompanies that somehow have a project governing body when there is muchfinancial resources to save. Although the quality of the projects is positivelyaffected by efficiencyThe aim is to find possible common weaknesses and strengths of the project systemby interviewing a number of project managers, and using the systems in placeexamine the model.As part of the work also includes examining what project managers have to adjust tothe newly implemented system VPMM, and other newly introduced elements thathave been added to improve the efficiency in the futureProject System is a complex system that is influenced by many different parametersand participating individuals' attitude and personality. But then small changes in themodel could have major economic consequences.The thesis has generated results that show common weaknesses among the variousprojects and their project managers' general opinions about the project model. It alsopresents some possible solutions based on own thoughts and those interviewedobjects suggestions and comments..

Inneluftsventileradekryprumsgrunder : en utvärdering av två tillverkare

This Diploma work investigates internal air ventilated crawl-space in respect to construction and damp. The Diploma work assumes from a general description of crawl-space and general dump problems in ground construction. An internal air ventilated crawl-space is a construction where you take the ventilation air from the building and bring it down to the crawl-space and lets the air circulate before it passes through a retaining aggregate on the way out from the crawl-space. In this matter you get a worm space under the building and a lot less dump problems in form of · Ground damp · Build damp The ground dump reduces through draining around the building, different layer of gravel between the ground and the building and ventilation of the crawl- space. The build dump reduces through ventilation of the crawl-space as fast as possible.

Problemställningen har såvida varit att bearbeta rören på insidan för att kunna applicera en svets och att kunna lokalisera om en defekt uppkommit i svetsen.

Investeringskalkyl baserad på ett flerbostadshus energiprestanda

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

Inköpsoptimering och kostnadsreducering

This thesis has been carried out at Diac Metal AB at Torsvik outside of Jönköping. The company produces parts for, amongst others, office furniture and store equipment. The essay will be concentrated on one detail which is included in many of their products.Today the company uses an ordering quantity based on experience which is rarely updated. Furthermore the operations are performed in both the company?s own engineering workshop but also an external workshop.The purpose with the report has been to check whether an updating of today?s batch shaping and ordering system can mean simpler storage control and possibly cost reduction.

Flödesapplikation - företagsbaserad utbildningsmodell på Internet

Intern företagsutbildning via e-learning är ett aktuellt ämne, framförallt eftersom företagen ser det som en chans att bli effektivare och spara pengar. Av de fretagsanpassade utbildningsapplikationer som finns på marknaden idag, är nästan samtliga skapta för att förklara fr användarna (kursdeltagarna) hur saker och ting ska fungera. Deras stora svaghet ligger dock i att förklara och förmedla varför dessa saker fungerar, varpå man riskerar att misslyckas med att förmedla en djupare förståelse och skapa en bättre kunskapsbas. Därför finns det troligen många anställda på företag som har fått lära sig hur allt runt om kring dem fungerar, men inte varför det nu fungerar som det gör. Denna examensrapport redogör för vårt arbete med att ta fram en webbaserad applikationsmodell, utvecklad i Adobe Flash, tilltänkt för utbildning, och som på ett enkelt men effektivt sätt synliggör hur olika typer av företagsflöden fungerar och, framförallt, varför de fungerar på detta sätt.

Ipv6 : En empirisk studie i hur Ipv6 protokollet har utvecklats de senaste åren.

Internet grows, so it?s cracking, soon will all IPv4 addresses be allocated and a solution is urgently needed. The new protocol, IPv6 is the solution to this problem. With a size of 128 bits against IPv4s 32 bits gives IPv6 a huge amount of addresses to distribute. The security addition that may be added manually in IPv4 is the standard with the new protocol.

Biblioteksservice till interner ? En fallstudie av hur nationella och internationella riktlinjer relaterar till biblioteksservicen till intagna på kriminalvårdsanstalten i Haparanda

The aim of this essay is to investigate how national and international guidelines relate to library services to prisoners in Sweden and to further illuminate this through a comparison with some examples from a few European countries. The essay examines what rights to library services Swedish prisoners are given in law, what national and international guidelines say, what demands are placed on the librarian in the form of education and suitability, what economical resources exist to realise library services to prisoners, what measures are taken to provide for language minorities, and how the security aspect is handled when it comes to computers and information technologies. The information has been obtained through interviews as well as through studies of books, articles and conference proceedings. The essay includes a small case study of how library services are provided for prisoners in Haparanda. Findings point to a gap between the goals that are presented in national and international guidelines and how the library services to prisoners function in reality..
