Renewable energy and the charging of electrical vehicles will increase in the future. Therefore the risk of outages is also increasing, partly because renewable energy is intermittent and the production amount can change fast. Charging electrical vehicles is often demanding high effect in short time, which could make faults occur. It takes more advanced technology to short the outage time. Today Övik Energi has high reliability in the power grid, but in order to maintain the reliability, it is time to prevent problems that can occur in the future. This thesis has presented a suggestion for the placement of fault detectors Protrol IPS2, in which a total of four detectors is proposed.

Projektformen blir allt vanligare i dagens utvecklingsarbete inom företag och dess verksamheter. Med fler projekt uppstår dock nya problem som exempelvis beroenden och resurskonflikter, det handlar inte längre bara om att genomföra ett projekt till utsatt tid och budget, utan även om att genomföra den rätta mix av projekt. På något sätt så vill man få kontroll på det kaos som uppstår i en multiprojektmiljö och det är här projektportföljstyrning, Project Portfolio Management (PPM), kommer in i bilden då detta är ett arbetssätt som underlättar prioriteringar och det löpande arbetet med flera projekt samtidigt.Studien syftar till att få en förståelse för vad projektportföljstyrning innebär och vad den innehåller. Studien syftar även till att visa på de viktigaste delområdena och faktorerna man bör fokusera på för att portföljstyrningen ska bli framgångsrik inom den verksamhet som ämnar använda sig av arbetsättet. Studien är dock avgränsad till vad projektportföljstyrning är, dels genom teori, men även enligt portföljchefer, konsulter och projektledare då det är dessa typer av aktörer som vi genom bekvämlighets och kedjeurval har intervjuat.

Some children develop externalizing and internalizing behavior problems at an early age. Previous research has often treated these children as a homogeneous group, the purpose of this study is to show that this group of children is in fact heterogeneous. Data from theSOFIAstudy was used and preschool pedagogues were informants. The sample contained 2121 boys and girls between 3-5 years. Groups of children with the behavior problems and the risk factors AD/HD symptoms, fearlessness and callous-unemotional traits were created.

My purpose with this work is to find out how it relates with pre-schoolteatchers view about a quality in comparasion to control document, Lpfö-98, and with factors pre-schoolteatchers consider effects quality in pre-school describe pre-schoolteatchers view on that high quality is in pre- school.The investigation has been done by quality interviews with five pre- schoolteatchers working in pre- school. The results show that they do not make a difference between what are high quality and the factors that affect the possibility of creating high quality. Most important is qualified and engaged educationalist in the pre- school who who shows a good attitude towards the children, and where development and learning is central. The most decisive to a pre- schools quality are the personell who work there. A conditon to achieve high quality in pre- school is a head who knows the pre- school activity and its curriculum, and who takes active part in the activity, invites to discussions and offers pertinent competence development.According to the leading document Lpfö-98 you will achieve high quality by offering children rear and care.

Wind and wind damage has become a hot subject because of the storm ?Gudrun? in January 2005. The main purpose of this study was to establish how the land owners attitude toward preventive wind damage actions was changing immediately after they had been struck by a storm. The result of the study was built on interviews. In springtime 2005 a total number of 20 private land owners were interviewed. Ten of the landowners lived in the province of Småland and ten in the province of Värmland.

Background: As a result of the financial markets ever ongoing product innovation a new derivative was introduced in the USA in 1997. A derivative that derived it's value, not from the price of an underlying asset, but instead from a climate factor. It's been known for a long time that revenue in certain industries are affected by weather conditions. The suppliers of weather derivatives claim that these weather sensitive businesses can user weather derivatives in order to lessen weather risk. Purpose: To do a critical evaluation of how weather derivatives can be used by companies as a risk management tool.

Abstract Over the years the consciousness of risk has grown. It?s hard to influence risks, therefore there are guidelines stating that significant risk must be included in the annual report. This paper is a case study; the purpose was to examine how four Swedish listed companies chose to disclose their internal and external risks. Risk is initially described in general sense and then it figures to what constitutes an economic risk.Through a case study of four Swedish listed companies? annual reports we have, through qualitative methods found how the companies chose to disclosure their risks.

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

Syftet med denna uppsats är att undersöka huruvida en aktiv individ får högre framtida pensionsutbetalningar än en individ som låter kapitalet vara kvar i Premiesparfonden.Vår undersökning har en deduktiv ansats, då ekonomiska teorier har utgjort grunden för de beräkningar som har gjorts. Beräkningarna bygger på hårddata, i form av historiska fondvärden, och studien är därmed kvantitativ. Tidigare undersökningar och beräkningar används för att styrka uppsatsen, som i och med detta är en sekundäranalys.  Den placeringsstrategi som visade sig ge högst framtida utbetalningar med hänsyn tagen till risken var den aktiva placeringen. De portföljer som de aktiva premiepensionstagarna har att välja mellan i vår studie, ger alla högre framtida utbetalningar än Premiesparfonden. Vidare kan tilläggas att Premiesparfonden är ett av alternativen som har för hög risk i förhållande till dess låga avkastning.Det skulle vara intressant att om några år, då Premiespar-fonden har förändrats till generationsfonder, göra om denna studie och då undersöka om detta leder till högre pensionsutbetalningar för de icke-aktiva premiepensionstagarna.Denna studie bidrar med och stärker, genom konkreta exempel, det som en del andra författare redan påpekat, att de icke- aktiva premiepensionsspararna får lägre framtida utbetalningar än de som är aktiva i sitt sparande..

Recent statistic shows that about 28% of adolescents living in Stockholm drink alcohol at such a high level that their consumption counts as risky drinking. The correct term to use in this matter would be binge drinking adolescents.  In the more wealthy areas of Stockholm this group of binge drinking adolescents counts for as much as a third of the population. In contrast, the adolescents living in exposed areas do not drink nearly as much. Binge drinking adolescents in these areas only counts for 15%, nearly half as much as in the wealthy areas.In light of this the intentions of this study is to investigate which explanatory factors that can clarify the range-rated differences in binge drinking between adolescents in Stockholm.

The production of oilseed rape is an important issue in Sweden and those who never have grown oilseed rape (OSR) are now willing to try. It is always a risk to grow oilseed rape, specially winter OSR, because of outwintering. This risk increases as you go north and therefore establishment and autumn growth is very important. These are some of the reasons that I have chosen to write about the establishment of winter oilseed rape in Middle Sweden. There are many factors that influence the outcome of the establishment, e. g.

The use of combi-drilling during spring tillage has become very common in southern Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and seed coulters, which means that the draught requirement is relatively high. It thus requires large, heavy tractors, which compact the soil and are comparatively expensive to buy and run. A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish market.

The primary aim of the current study was to gain increased knowledge about drivers' risk experiences. The study was based on questionnaires answered by 30 private drivers and 30 bus drivers, with 50% men and 50% woman in each group. The study revealed no differences, either between men and women drivers with regard to their experience of risk, or between the groups of private and bus drivers. Gambling is common within the private drivers group. Mistakes are common in all groups.

Den här uppsatsen behandlar organisering av applikationsportföljer. En applikationsportfölj är enligtvår definition i denna uppsats det samlade antalet applikationer som finns inom en verksamhet ochen applikation är ett informationssystem som används direkt i verksamheten. Med organisering menar vi i denna uppsats hur ett systemstöd för styrning av en applikationsportfölj kan strukturerasoch vad det bör finnas för information om varje applikation.Uppsatsen redogör för ett antal undersökningar som vi har genomfört på olika affärsenheter inomSaab Group i Linköping och Huskvarna samt en undersökning på ett referensföretag undersommaren 2009. Syftet med uppsatsen är således att undersöka hur en koncern kan organisera engemensam applikationsportfölj. Vi kommer dra nytta av lärdomar från de olika affärsenheterna och tre teoretiska fält i vår undersökning: Application Portfolio Management, ITIL och affärsmässigförvaltningsstyrning.

The purpose with this thesis is to get a compilation of all the critical bolted joints of all enginesproduced at LV Motors. ABB LV Motors produces induction engines with seven shaft heights. Eachengine size exists several variants of components ex. standard shield and flange shield. Depending onwhich components the engine is equipped with arises various types of strains in the engine's parts,certain assembly ways are more favourable than other.The most critical parts in the engine from a mechanical point of view are the screw units betweenshield/stator, feet/stator and bearing cover/shield.
