Kompensering av reaktiv effekt vid vindkraftverk

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.

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.

Mässa tur och retur : En intervjustude, enkät och observation

This paper deals with the question of why companies choose to go on trade fairs and exhibition examines how the media works. The essay's main focus is on stand contractors and why those hired to produce other company stands. The study is based on three interviews, a visit to a trade fair and a questionnaire survey. Together with the relevant literature is given a clear picture of how companies are thinking in their choice of attending the fairs, but also why stand contractors are involved in the process. We concluded that some companies do not know why they participate in fairs and many feel compelled to contribute to not be forgotten in the market.

Riktlinjer för mobil applikationsutveckling

Marknaden för mobila system har utvecklats enormt snabbt de senaste åren. Idag är det ett område med en allt större omsättning och det har vuxit fram som en helt ny gren inom Software Engineering. Utvecklare av mobila applikationer står ständigt inför en utmaning när det gäller att välja vilket mobilt system man ska satsa på när man utvecklar applikationer. Valet av system kan vara helt avgörande för om man hittar rätt målgrupp av konsumenter och därmed kan generera tillräckligt med omsättning för att driva lönsam utveckling av applikationer. Det räcker inte att enbart kolla på vilket system som har mest användare eller vilket system som genererar mest omsättning, utan man bör noggrant överväga de förhållande som gäller för just den applikation som ska utvecklas.

Tesauruskonstruktion i ämnet landskapsplanering

This research paper is a thesaurus construction for the interdisciplinary subject of landscape planning. The personnel doing the indexing of documents at the Swedish University of Agricultural Sciences had earlier expressed a need for such a work within the fields of Landscape Architecture and Landscape Engineering. However our objective was not to create a complete thesaurus, but instead a basic construction which the personnel at the Agricultural University could expand upon. The actual construction is based upon ISO 2788-1986, Documentation Ð Guidelines for the establishment and development of monolingual thesauri, and Aitchison, Gilchrist and BawdenÕs Thesaurus Construction (1997). The line of enquiry taken has dealt with the problems relating to the collection, selection and control of indexing terms.

Enkla kemiska processer inom förskolan : En kvalitativ intervjustudie om förskollärares uppfattningar och tankar om läroplansmålet enkla kemiska processer

The aim of this study was to investigate preschool teacher?s perceptions about the curriculum goal concerning simple chemical processes. The result was based on narratives received by a qualitative study and semi-structured interviews of six preschool teachers. The results of the study showed that preschool teachers perceive that they actually are working in a relatively small scale with simple chemical processes and they do not really know what simple chemical processes are, and do not feel very familiar with the subject. Water, dough, mud, paint and baking were the most common activities that were used when working towards the curricular goal. However, it was never explained to the children that it was simple chemical processes they were working with during the activities, neither was it discussed among colleagues because of the uncertainty about the concept.

Studie till uppstartande av annonskatalog

Sten Jonsson wants to start a production of an advertising catalogue for small companies in Sweden. Acatalogue where the advertisingcost is so low that most of the companies can afford to participate. Thecompanies who will advertise should be manufacturing companies in trades of carpentry, sheet metalworkshops, forging workshops and engineering workshops.The catalogue will facilitate for the manufacturer to reach the costumer without any middleman.Without a middleman creates a possibility for an opinion about the product at the same time as theprice can be held low. A catalogue of this type would benefit the marketing of the companies at the sametime as it would generate an occasion for innovations.The possible target groups are property companies, construct companies and farmers.A market research has been carried out contained a postal interview and a phone interview. Themarket research carried out to get an understanding in what the companies think about the idea butalso to see if the companies are in interest of advertise in the catalogue.

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

Minimumkrav för ett CI-system

När en grupp utvecklare jobbar med samma kodbas kan konflikter uppstå med avseende på implementationen av moduler eller delsystem som varje utvecklare individuellt jobbar på. Dessa konflikter måste snabbt lösas för att projektet ska fortskrida och inte stagnera. Utvecklare som sällan kommunicerar framför ofta okompatibla moduler eller delsystem som kan vara svåra eller omöjliga att integrera i kodbasen, detta leder ofta till s.k. ?integration hell? där det kan ta väldigt lång tid att anpassa ny kod till en befintlig kodbas. En strategi som man kan ta till är ?continuous integration?, ett arbetssätt som erbjuder en rad fördelar när man jobbar i grupp på en gemensam kodbas.

Riskanalys på Karlshamnsverket - Påverkan vid en framtida höjning av havsnivån

Människan har genom sin industriella framfart bidragit till ökade nivåer av växthusgaser i atmosfären och på så sätt rubbat den balans av gaser som naturligt förekommer. En klimatutveckling med trender som tyder på en framtid med varmare klimat är en av konsekvenserna av den process vi i alldagligt tal benämner växthuseffekten.Ett varmare klimat förväntas medföra förändringar av en rad faktorer, där medelvattenståndet i världshaven är en. Med en geografisk lokalisering i direkt anknytning till kusten och en topografisk lokalisering på dryga 2.65 m över havet skulle Karlshamnsverket kunna vara i farozonen för de konsekvenser en höjning av intilliggande hav kan medföra. Karlshamnsverket är ett värmekraftverk som ägs och drivs av Karlshamn Kraft AB. Anläggningen ligger utanför Karlshamn, vid Blekinges kust, och redan idag råder viss problematik vid högvattenstånd.
