Förändringar av marknadsdesign och deras påverkan på balanshållningen i det svenska kraftsystemet : En kartläggning och analys av de balansansvarigas arbetsgång
A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design: Increase the imbalance costsIntensify the regulation of imbalancesIncrease the temporal resolution on the different marketsPresent the prices for balancing power in real-timeModify the balancing market to simplify auction of consumption bidsA mapping over the BRPs? processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis.
?Vård i annans hem? - användning av arbetsmaterialet i Huddinge kommuns hemtjänst/boendestöd och personlig assistans
AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.
Matchmaking på organisatorisk nivå : ? om samverkan mellan kommunala introduktionsenheter och frivilligorganisationer
AbstractMatchmaking on an organisational level? about co-operation between municipal introduction-units and voluntary organisationsEssay in Political Science D, by Rebecka Johansson, spring 2006The aim of this study is to examine co-operation between municipal introduction-units, which work to integrate newly arrived immigrants and refuges, and voluntary organisations in Sweden. The essay is a comparative case study which examines three local authorities and the main questions are;- Do voluntary organisations constitute a functioning co-operation partner to the municipal introduction-units? Are there conditions for future co-operation?The answer to the questions is that there are no, or rarely any, co-operation between voluntary organisations and municipal introduction-units. It is difficult to judge whether there are conditions for future co-operation.

Verksamhetsstyrning fo?r lokaleffektivisering inom kommunal verksamhet : ? En fallstudie av Halmstad kommun
Title: Management control of facility efficiency in municipalities - A case study of Halmstad municipalityLevel: BachelorSeminar date: 2012-05-31Authors: Markus Nilsson & Sara MattssonAdvisor: Sven-Ola CarlssonKey words: Control management in municipality, facility efficiency, management by objectives, internal rents and incentivesBackground: The public sector owns and manages a large property portfolio and in the municipalities, the properties are always a big cost item. Because of the outside world changes and the public interest, the properties should be used as efficiently as possible.Purpose: The purpose of this paper is to describe how control management of facilities looks like a municipality. The paper also seeks to explain how employees work to make the facilities more efficient in a municipality.Methodology: The authors use a qualitative method with open interviews.Theoretical perspectives: The choice of theory was made with the field of management control and facility efficiency in mind. The theory therefore includes management by objectives, internal rents and reward systems, motivation and communication within organizations.Empirical foundation: The organization has undergone a reorganization 2010/2011. There are no clear incentives to reduce facility costs.
Produktivitet och lönsamhet vid skogsbränsleuttag i klena gallringar : en tidsstudie av Vimek 608 BioCombi i contortabestånd
The annual demands for forest fuels increases in Sweden. At present, large unutilized biomass resources is found in young, dense forests from which about five million oven-dry tonnes (ODt) (23 TWh) could annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The time study was performed in Åmarken in the county of Västerbotten.
Massivträ : Jämförelse mellan olika principer för sammanfogning av trä till plattelement med avseende på pris, hållfasthet och ekologi
Ökad användning av byggtekniken massivträ kan ge ett positivt bidrag till hållbart byggande. Utvecklingen inom datornavigerad bearbetning ger massivträ möjligheten att rationalisera byggproduktionen inom trä. Tekniken ligger rätt i tiden och kommer att värderas allt högre då den tillvaratar materialets karaktäristiska egenskaper.Utvecklingen av massivträ har resulterat i teknikvarianter av hur virke kan sammanfogas till solida element. Ett behov har funnits av en marknadsjämförelse mellan befintliga principer där studien förtydligar grundläggande skillnader för intresserade byggaktörer. Problemfrågan för denna studie har varit: vilka principer för sammanfogning av trä till plattelement inom massivträ är mest fördelaktiga? Detta sett utifrån faktorerna produktionskostnad, hållfasthet och ekologiska övervägningar.För att förtydliga den undersökta byggmetodens nytta i ett vidare perspektiv har det presenterats en allmän beskrivning av massivträ.
Att återställa en naturlig ordning : skogshistoria och restaureringsbränning i Långsidbergets naturreservat
During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results.
Långsidberget is located close to areas that were colonized during the Middle Ages.
Hur publicera efter policyn? Ett antal seniora forskares förhållningssätt till open access efter Vetenskapsrådets open access-policy.
Since the 1990?s Open Access has developed into an alternative model for scientific publication. Today an increasing political interest in promoting Open Access is commonly channeled through the implementation of policies by research funders. However, in the scientific community the uptake and acceptance of the model has been of notably different character.This Master?s thesis examines the understanding of and attitudes towards open access among eight senior Swedish researchers and how these have been affected by the implementation of the Swedish Research Council?s Open Access-policy as implemented in 2010.
Fastighetsbestämning och särskild gränsutmärkning i Sverige
The purpose of this thesis is to describe property definition and special boundary demarcation and to analyze the differences between the two cadastral procedures. Property boundaries, especially unlawfully determined boundaries created through unofficial parcelling, can create conflicts between landowners and make it diffi-cult to know which land that a property contains of. It is possible to clarify the boundary conditions through a property definition or through a special boundary demarcation re-establish boundary marks.The methods used are: (1) A literature review to collect background information, (2) A case study to summarize court cases and (3) A questionnaire study to collect opinions from cadastral surveyors.The result is summarized in two comparisons. Firstly between restoration of landmark and special boundary demarcation (which replaced restoration of landmark in a legislative change in 2010), which demonstrated that the change in the law is considered positive because special boundary demarcation gives a legal effect on the boundaries. Secondly between property definition and special boundary demarcation which demonstrated that the two procedures are similar to each other.
Fastighetsunderhåll : Arbete med underhållsplaner i stora fastighetsbolag
Background: The standard of living should be the same for everyone, whether the apartment is placed in an old or new building. The residential properties that were built from 1965 until 1974 is now beginning to become old and in need of restoration. The financial crisis during the nineties contributed to the lack of maintenance on the buildings in Sweden. As the public buildings gets older more and more defects occurs. The coordination and maintenance will therefore have a more significant role in the housing company ?s work.The increasing interest about how old a building can be, attract much attention.
Föroreningar orsakade av stenar inblandade i barrmassaved
Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.
Leder ESBL-producerande bakterier till ökade samhällskostnader i Sverige?
Due to long time of overconsumption of antibiotic, the possibility of an effective infection treatment is now threatened. Bacteria have begun develop resistant against antibiotic, witch is most due to bacteria that do not normally develop resistant. These kinds of bacteria produce ESBL, and have made the healthcare costs increase around twice as much, as for bacteria that do not produce ESBL..
Marknadsundersökning för SCA Skog AB avseende utbor i Mälardalen :
The need of raw material does of course fluctuate but the long term view is an increasing demand due to the growing consumption of sawn timber products, pulp, paper and lately also biomass. This has led to a keener competition for wood. At the same time there is an ongoing structural change of a significant part in the Swedish wood supply market, the private forest owners. In 1992,
22 % of Sweden´s 335 000 private forest owner lived apart from their forest. In 2007 this figure had risen to 36 %.
