Excel-baserad beräkning och dokumentation av distansskyddsinställningar

This is a master thesis work carried out at the Department of Energy and Environment atthe Division of Electric Power Engineering. The master thesis work describes the theoryof distance protection relaying in 130 kV meshed distribution networks. The main aim ofthe thesis was to construct an Excel application for calculation and documentation of thesettings for distance protection relays. The program is based on general methods forcalculating settings of the different zones for the distance relay and presents the settingsin simple graphics using quadrilateral characteristics.The reason for building an Excel based application is the great variety of distanceprotection relays in live networks. The manufacturers of distance protection relays makeprogram for documentation available, however, they are based on the typical settings forthe specific relays.

Hur ska tall- och gran bestånd i Götaland gallras för att minska risken för vindskador?

With knowledge of how the southern Swedish forests have been affected by storms the past years, this study intended to find out which factors affect the storm firmness of a stand the most. The study was based on data from stands in the, by the storm Gudrun, affected area. The results of the analyses that tested the stand factors that influence the amount of storm damage to the greatest extent showed that the storm sensitivity of Norway spruce stands were largely due to previous management actions. The factors that could be controlled by thinning and had relevance of storm damage standpoint, according to the results were; the dominant height, volume, basal area weighted mean diameter and stand age at last thinning. In this study, these results are not as clear for Scots pine.

Perspektiv på Personalutköp : En utredning av en alternativ lösning för avslutande av anställning

This essay investigates employee buyouts and does so from a number of different perspectives. Employee buyout is a term that describes a way of ending an employment through an agreement where the employee gets a sum of money in exchange of leaving their employment. Technically it is neither a resignation, since the employee gives up the employment in exchange of money, nor a dismissal since the employer does not have legal grounds for dismissing the employee. Employee buyout is not an illegal way to end an employment, as long as it is the result of a mutual agreement between the employer and the employee. In this essay I investigate and analyze employee buyouts in relation to 7 § in the Swedish employment protection act, and also Swedish employment protection in relation to regulations from EU regarding employment protection.

Produktivitet vid selektiv mekaniserad bioenergiröjning av eftersatta röjningsbestånd :

In Sweden, harvesting pre-commercial thinning (PCT) stems for energy purposes is a interesting way of financing the high cost of preparing dense stands for a profitable first conventional thinning. This concept can be labelled bioenergy thinning. The aim of this study was to quantify the productivity of a Vimek 404R light harvester with an accumulating Naarva-Grip cutting head during the bioenergy thinning of a self-regenerated stand west of Sunnansjö in Dalarna. The stand was birch-dominated, contained 15 371 stems/ha, and measured on average 4,6 cm Dbh and 7 m tall. Even though the driver was well experienced with the machine, the stand in question was the first one that he ever thinned in this manner. Nevertheless, the driver strived to accumulate as many stems as possible during each crane cycle and chose to cut taller stems in half so as to make the handling and forwarding of the harvested stems easier.

Meddelartrygghet : För privatanställda på offentligt finansierade jobb

This paper examines how notifies security looks for private employed workers in jobs founded by the public. The aim is to clarify the legal situation surrounding notifies law, and to analyze possible shortcomings in the law with a focus on the future.Notifies law is based on five cornerstones. Where freedom of information, a right to provide information to the media for publication, ?acquires the right? and protection to be anonymous when talking to the press goes to all workers. The other two pillars, ?a look up prohibitions? and ?retaliatory forbid? apply only to employees in the public sector.

Utökat ballistiskt skydd mot finkalibriga projektiler på ytstridsfartyg

Detta arbete handlar om med vilka material som det ballistiska skyddet mot finkalibriga projektiler kan förbättras på befintliga svenska ytstridsfartyg. Eftersom det befintliga fartygets konstruktion i sig innehar en viss skyddsförmåga (grundskydd) behöver denna inledningsvis beskrivas för att definiera utgångspunkt.Att förbättra skyddsförmågan genom att komplettera den redan befintliga konstruktionen med tilläggsskydd innebär att fartyg får helt förändrade förutsättningar att klara av nya hot och uppgifter och därmed också få en förbättrad livslängd.Genom att studera för- och nackdelar hos olika tekniska lösningar framkommer vilka som är realistiska.Fartyg kommer sannolikt att utrustas med olika material eftersom ytor- och utrymmen kommer att behöva prioriteras. Olika materialval kommer också att styras av kompromisser mellan ballistiskt skydd och lastbärande konstruktioner..

Biotopskydd av stenmurar : Skäl för dispens

Stone walls in agricultural land are incorporated in the general protection of biotopes. They are protected because they provide a habitat for endangered species. Therefore it is illegal to carry out proceedings in an area that is included in the protection of biotopes. In order to do that, exemption is needed which can only be granted if there are special reasons. The essay stipulates what these special reasons are.In an exemption errand the interest for nature conservation must be weighed against a public or a private interest.

Integration av systematiskt brandskyddsarbete med ISO 14001

As a result of the Civil Protection Act, there is an imperative for Systematic Fire Preventive Measures, SFPM. SFPM can be divided in two parts: organisational preventive measures, and documentation of fire preventive measures. The manner in which SFPM is to be conducted is similar to that of the environmental management system ISO 14001. This report provides suggestions how to integrate SFPM with ISO 14001..

Turordningsreglerna - snart ett obsolet arv?

Sweden's contribution to the world today is not labor-intensive industry, it is high technology and know-how. Many of the rules concerning employment security for the workers derived from the industrial era and have been to some extent modified by hand. This paper focuses on the discrepancy between the purpose of the priority rules in Swedish law and how it works in the reality. My opinion is that due to the development of the labor market, a powerful revision of priority rules is needed. In addition to today's job market is knowledge-intensive I point in the paper at a number of factors that contributed to the loosening of the priority rules. Examples of these are the increased incidence of temporary staffing, more open markets and more multinational companies, political will to disadvantaged groups in the labor market should be prepared job and gender issues.

?Säg inget ont om Bellman till Fred Åkerström: Då åker du på en propp!? : En C-uppsats om Fred Åkerström som Bellmantolkare

This essay is about the Swedish folk and troubadour singer Fred Åkerström and particularly his interpretations of the Swedish national poet Carl Michael Bellman. With Åkerström being a socialist, he converted his beliefs into what he believed Bellman should stand for and not stand for, politically and historically and the picture he did not take kindly to is called "The bourgeoisie". And in his interpretations of Bellman Åkerström used his deep bass voice and singing with maximum potential that earned him the nickname "Carl Michael Decibelman" along with a trio he created called Trio CMB. But along with alcoholism and financial problems Åkerström died at an age of 48 years old and had probably much more to give the Swedish musical society..

Erosionsskydd i strandzoner :

Erosion in coastal areas is a common problem all around the world. The range of the problem depends on several factors, i.e. type of bed-rock and soil, wind and wave climate. Another factor is whether the area is of high interest, i.e. if the area is important for tourism and recreation, if there are houses and other buildings close to the shoreline or if it is a site of special scientific interest.

Produktivitet och lönsamhet vid skörd av skogsbränsle i klen björkgallring :

The aim of the study was to compare productivity in first thinning of birch stands, when either energy- or pulpwood was harvested. The systems total profitability was also compared by including forwarding and chipping costs. A Gremo 950 HPVR harvester was used and the same driver was used under the entire study. During the pulpwood harvest a Logmax 4000b harvester head was used and a feller buncher head made by Silvatec was used during the energy wood harvest. Six study unit pairs were located in a birch dominated stand outside Ängelholm in Skåne.

Hållbart jordbruk inom vattenskyddsområde : En studie om Sverige, Danmark, Frankrike och Tyskland

To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.

NESCAR

I love contrasts and meetings between people. Situations where individual differences are highlighted, affected and shaped by each other.In this project I have been working with five characters: the aggressive one, the frightened one, the social one, the reserved one and the proud one. By analyzing the characters I have tried to understand how they are able to meet and agree with each other. The goal has been to create a place where this can happen, but which is also adapted for each respective character.The project is based on a field study I did in the summer of 2013, when I lived in a masai village in the northern part of Tanzania. Nescar is the name of a masai women I got to know, is means The one that you can trust.
