Riskvärdering har under 90-talet blivit ett allt mer medvetet begrepp. Ett populärt instrument vid riskvärdering är Value at Risk då denna modell skapar ett gemensamt riskmått för olika typer av portföljer och derivat. VaR mäter den maximala värdeförändringen för en portfölj där sannolikheten och tidshorisonten är förutbestämd. I uppsatsen har en konfidensnivå på 95 procent antagits vilket medför att de verkliga förlusterna ska överstiga VaR en gång av tjugo.Icke-linjära instrument, såsom optioner, är svåra att riskvärdera då dess pris förändras oproportionerligt gentemot dess underliggande. För att beräkna VaR kan flertalet modeller appliceras och dessa har olika egenskaper.Det är därför av intresse att ta reda på om Delta-Normal metoden, Monte Carlo simulering och Historisk simulering ger samma svar vid riskvärdering av optioner.

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

The Swedish model for developing the national infrastructure is based on increasing the cooperation between municipalities, government and businesses. The method to establish the infrastructure in Sweden is the geodatastrategin. The effort to implement the geodatastrategin has resulted in an interaction model, Geodatasamverkan. The purpose of this study is to alert municipalities and to investigate the usefulness of their participation in Geodatasamverkan. The study also presents examples of different applications where geodata can be used within a municipality. The report is based on literature reviews, surveys and interviews. Online Surveys were sent to some of Sweden's municipalities to get an overall idea of ??how they make use of geodata and their general attitude towards Geodatasamverkan.

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

Introduction: Malnutrition leads to loss of health and coexists with disease and loss of function. A good nutritional status becomes more important the older you get to maintain a good health. Studies show that it is important to identify and prevent malnutrition in its early stages. Men and women recieve different medical treatment in a number of different medical diseases. There are few studies in nursing from av gender perspective.Aim: The aim of this study is to examine the prevalence of malnutrition in the elderly in Västra Götaland with focus on gender differences when it comes to prevalence and nursing interventionsMethod: A register study with av quantitative approach is conducted to answer the aim.

Canine parvovirus is associated with two disorders: enteritis, which is common, and myocarditis, which is rare. Prominent clinical signs of parvovirus enteritis are vomiting, diarrhea and rapid dehydration. Canine parvovirus type 2 (CPV-2) is very contagious. When CPV-2 first emerged it had high rates of mortality, but later studies have shown that most infections are self-limiting and do not require veterinary care. Mortality rates vary greatly, and therefore it is important to determine risk factors for developing severe canine parvovirus enteritis.

This essay concerns the possible tabloidization of Swedish daily newspapers. To investigate if tabloidization theory could be supported, a case-study is made using the isolated crisis of an especially big forest-fire in the county of Västmanland in Sweden in the summer of 2014. One local paper of the daily press, Vestmanlands Läns Tidning and one tabloid-paper with a national spread, Aftonbladet, are compared using quantitative content analysis to see whether there are similarities or differences enough to support or reject that the daily press is under influence of tabloidization. The results of the two papers news coverage of the fire are compared in three main categories; Theme, Source and Value-words. These categories represent three of tabloidization?s main criteria; ?soft news?, personification of sources and more use of words that connote strong values as signs of a lower quality in journalism.

The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.

Trycksår är en vanlig komplikation hos patienter som drabbats av höftfraktur. Syftet med denna systematiska litteraturstudie var att finna betydelsefulla riskfaktorer för trycksår hos patienter med höftfraktur för att sjuksköterskan omgående ska kunna identifiera en patient med hög risk. Metoden som använts för denna litteraturstudie var en modell med sju steg för ett systematiskt tillvägagångssätt. Litteratursökningen utfördes i databaserna PubMed, CINAHL och The Cochrane Library. Kvalitetsgranskning av studier utfördes med ett protokoll av Willman m fl (2006) modifierat av författarna.

Umeå Energi are working towards a goal, that in the year of 2018, they will be completely climate neutral. As a part of this, one target is to reduce their grid losses by 4 % of the 2012 level, which corresponds to an overall reduction of the grid losses of just over 1.7 GWh. In many residential areas, the distribution grid is designed and rated for electric heating as the heating in the houses. As many of the houses later has been converted to other types of heating, their electricity use has decreased and the total power output from many of the secondary substations has decreased significantly. Because of this, many of these stations today are well oversized, which in turn means that the energy losses in these stations are unnecessarily high.In this degree project, 25 secondary substations have been studied, all located in residential areas in and around central Umeå.
