Modell och analysverktyg för beräkningav frekvensförlopp

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Jordbrukets påverkan på Östersjön : en jämförelse av indikatorer för att beskriva näringsbelastningen

The Baltic Sea, due to its special conditions, is a unique and vulnerable marine environment. There are many pressures that have an impact on the sea and one of the major problems is the extensive flow of nutrients from land. The most visible effect of the supply of nutrients is the annual algal blooms. One of the main sources of nitrogen and phosphorus supply is agriculture. Nutrient losses from arable land have been increasing as agricultural production has intensified. At the end of the twentieth century an increased awareness of these problems led to the formation of organizations such as HELCOM and Baltic 21.

Organisatorisk förändring och omladdning av varumärke

Abstract Uppsatsen behandlar ämnena organiatorisk förändring samt varumärkesladding. Även identitet, profil och image diskuteras. I arbetet har vi använt oss av Lindex som fallföretag. Omladdning av ett varumärke blir aktuellt när märkets brand equity stagnerat eller när företag önskar förändra de värden som är kopplade till varumärket. Detta tillsammans med en organisatorisk förändring har varit aktuellt i vårt fallföretag Lindex.

En conjoint analys av förpackningsattribut.

Abstract Title: A conjoint analysis of packaging attributes. How can the attributes of a product?s packaging best look like to attract the consumer? Authors: Linda Granberg & Helena Niklasson Supervisor: Jan Svanberg Department: School of Management, Blekinge Institute of Technology Course: Bachelor?s thesis in Business Administration, 15 credits Purpose: The purpose is to find out how visual and technical attributes on product packaging affects the consumers tendency to want to buy the product.

The consumer wants it to be simple and easy to use, the people under time pressure seeks product with new technology which can save them time..

Utveckling av en dynamisk Simuleringsmodell av en skotare

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

VD:s ord i förändring : En studie om förändringar av VD:s ord i årsredovisningar före och efterfinanskrisen 2008

Annual reports are by many considered to be companies primary way to inform their world where the CEO's words are read most carefully by shareholders. The purpose of this paper is to examine the design of the CEO's words in annual reports in light of the financial crisis in 2008. The study seeking explanations for change, similarities and differences in the various texts based on three themes which are results, future and confidence. In this qualitative study five CEO's words are explored by means of a discourse analysis, all from large Swedish industrial companies listed on the Stockholm Stock Exchange. Some of the results shown is that the CEO tends to talk about the company's results in a self-serving manner and CEO speaks more aboutm the results before than after the crisis.

Pedagogens inverkan på elevgruppens beteende i klassrummet

 My goal with this essay was to find out what makes certain teachers more successful than others to hold good and well functioning classes. This is important because this in turn affects the learning of the students. I wanted to find out what factors people within the world of research have pointed out as important aspects when creating a good teaching situation, with focus laying on the teacher?s behaviour in the classroom. In my investigation I have used qualitative research, observing two upper secondary school classes, for a total of nine lessons during a two-week period. In my observations I wanted to see if the class as a whole was behaving differently when interacting with different teachers.

Driver hushållens skulder konsumtionen? : En jämförande studie av Sverige, Norge, Danmark och Finland

The consumption levels in Sweden, Denmark, Finland and Norway have been rising fo r the last decade. Even after the financial crisis of 2008, consumption levels continued their upward trend, regardless of the recession. The explanation seems to be, at least partly, that households tends to increase their debt ratio in order to continue the same standard of living as before in terms of consumption. It is clear, based of our results, that there is a connection between increased consumption and debt ratio for households. And the consequences of allowing loans to finance a sustained or increasing consumption may ultimately be difficult to manage.

Från färdighetsträning till vokalt uttryck : Om sången i grundskolans läroplaner

The subject singing in elementary school changed its name to music in 1955 and with the name change followed a change in the content of the topic. In my study, I examine the perspective of how song as a subjekt has changed in the basic school curriculum texts. As a complement to text analysis, I used interviews in which two music teachers with long service in primary school were interviewed. My survey shows that there has been a clear change of the contents of concept song from being a pure skill where the aim was the vocal line benefits in different contexts and is today a vocal expression that can be embodied in many different ways. Curriculum texts have not been crucial to the changing content of the concept song.

Studie av klimatets variation på breddgraden 59 grader nord

Med klimat avses statistiska väderförhållanden såsom temperatur, nederbörd, vind, et cetera.  Dessa statistiska förhållanden skiljer sig mycket på olika platser på jorden. I detta arbete har klimatet för en viss breddgrad runt hela jorden studerats och hur klimatet beror av geografiska förhållanden såsom berg och hav. Breddgraden är vald till 59±2 grader nord. På denna breddgrad förekommer både stora kontinenter och världshav med stora skillnader i till exempel topografi och avstånd till hav/sjöar.För att kunna studera detta har data över månadsmedeltemperaturen och månadsmedelnederbörden samlats in från en klimatdatabas (www.worldclimate.com).

Lärares uppfattning om yrkets statusförändring under 30 år : En intervjuundersökning om åtta lärares uppfattning om yrkets statusförändring

This paper is about how the teaching profession have got a changed status from the perspective of the teachers. The papers cause is to find out how the teachers think that their status have changed in a period of 30 years. Interviews have been done with eight middle school teachers from two schools in the municipality of Södertälje. The answers from the interviews have been put in relation to theories in research of professions. Three hypotheses have been put up to apply the theories on the answers.

Rekommendationer eller konversationer - Effekten av innehållet i word of mouth på mottagarens inställning till det omtalade företaget

We investigate the effects of various types of word-of-mouth (WOM) messages on consumer bahavior. The message is varied along two dimensions where one is valence and the other is whether or not it contains an explicit call for certain behavior or attitude change. We use an experiment in the form of a web-based survey. Five different scenarios were designed to represent neutral, positive, and negative WOM. The latter two came in two different versions - one with a recommendation and one without.

Gränsdragningsproblemet i luck egalitarianism

The purpose of my study is to investigate whether luck egalitarianism can be savedfrom its inability to draw a line between risks which can reasonably be expected to beavoided, and risk which can not. Such a demarcation is of particular importance forthis influential theory of distributive justice, since it serves to judge whether a personis entitled to compensation for a bad outcome of a taken risk, or not. Testing theintuitiveness and coherence of various contending principles for how to separateavoidable risks from unavoidable ones, I conclude that luck egalitarianism seemsunable to draw a clear line between the two kinds of risks. Instead the theory appearsto be dependent on conceptions of a 'normal life', making it remarkably vague.Furthermore, I argue that luck egalitarianism seems unable to manage without takingsufficientarian and utilitarian concerns into account, for the purpose of decidingwhich risks are avoidable, and which are not..

Logistik i små företag - En analys av problem och möjligheter för STARKA

In order to suggest improvements for the logistics of STARKA, we felt that we had to analyze all the activities which were related to STARKA's logistic processes. Our primary analysis consisted of a rough but comprehensive description of different functions in the company, and the relationship between them. This was performed by following a typical order through the company to see which functions were affected by the order.Since we needed a more thorough view of the company, we decided to analyze the different products STARKA currently has on the market, focusing on economic data such as turn-over, profit, profit margin, deficiency cost and cost of warehousing. We also analyzed the company's choice of manufacturing processes, organization, warehousing processes, strengths and weaknesses.These analyses gave us a clear understanding of the company and its processes. STARKA is a small, function oriented company with a wide range of products.
