Saltvattenuppträngning i Göta älv? Inverkan av förhöjd havsvattennivå på råvattenintaget vid Alelyckan
This master thesis investigates the possibilities of using GPS-information from trains to create a model of a railway system, register the routes of the the trains and predict how the trains will travel in the railway system.The thesis work was done at Icomera AB which is a company that specializes in internet connected vehicle solutions.We describe how the GPS-information is sent from the trains in the form of samples and investigate limitations and possibilities with the available information. About three million samples from 83 SJ-trains were analysed and the samples were filtered with the intent of removing erroneous information. We here found that about 30 % of the samples from the trains were unreliable.A solution for how the samples from the trains can be used to create a model of the railway system traveled by the trains is presented. We use a large set of historical samples and use cluster nodes and Hermite curves to generate a graph that represent the railway system with stations, nodes and the railway itself. A fully automatic solution is not presented since it did not fit into the time frame of the thesis; instead we created a simple tool which can be used to manually finish the model of the railway system.Furthermore, we describe how the railway system and the samples from the train can be used to register the routes the trains travel.
Handel med utsläppsrätter inom EU - Möjlighet eller papperstiger
This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.
Kundens förtroende och bild av fastighetsmäklare i Karlstad
Hälsans Trädgård is a project which is going to start in Gamla Linköping, Sweden. The authors were commissioned by Arbetslivsresurs, a company working with work rehabilitation, to select, define and make job analyses on five work tasks at Hälsans Trädgård in Gamla Linköping. A job analysis means an analysis of the demands the job make of the individual. The job analysis used in this study is called The Revised Handbook for Analyzing Jobs (RHAJ) and is from the US Department of Labor (DOL). As RHAJ is an American instrument, the authors produced a form where the concepts are translated into Swedish to make the analysis easier.
Går det att förutspå konkurser? : En jämförelse mellan olika modeller
Bakgrund: Många företag går i konkurs varje år vilket är förknippade med kostnader för de enskilda intressenterna och för samhället i stort. För att kunna vidta eventuella åtgärder innan konkursen är ett faktum är det av intresse att veta om någon av de modeller som forskare tagit fram för att förutspå konkurser faktiskt fungerar.Syfte: Syftet med denna undersökning är att ta reda på om det går att applicera någon av ett urval av etablerade konkursmodeller på svenska industri- och tillverkningsföretag.Teori: Studien kommer att testa tre olika forskares modeller och metoder: Altmans, Platts och Platts samt Pompes och Bilderbeeks.Metod: I denna studie kommer enbart en deduktiv forskningsansats att användas och datainsamlingen är kvantitativ då nyckeltal hämtas från de aktuella företagens årsredovisningar. Urvalet baseras på de företag som ansökte om konkurs under år 2011 och de som representerar kontrollgruppen har slumpmässigt valts ut bland de företag inom avgränsningen som inte gått i konkurs det aktuella året.Resultat och slutsats: Altmans och Platts och Platts modeller visar sig inte vara applicerbara på svenska företag. Dock är vissa av Pompes och Bilderbeeks nyckeltal tillämpliga till att använda för konkursprognostisering för svenska företag..
?FÖR MIG FUNGERAR INTE ?KOM IGEN, NU KÖR VI?? : Leder ökad chefsmotivation till ökad motivation hos de anställda?

Utvärdering av protesfötter med hjälp av en konstruktion som kan utföra en mekanisk gång.
This paper has evaluated a new type of prosthetic foot, X-Balance, which aim was to facilitate the performance on uneven ground for the user. This study have performed gait analyzes with three prosthetic feet, the X-Balance, Flex-Foot and assure Ottobock9192 on flat and uneven surfaces using 3D analysis system QTM (Qualisys Track Manager) and associated force plates. During the project a prototype of a design that can perform a mechanical gait were manufactured. The prototype has then been used to fulfill the purpose and objective of this study which is to make different final sets that demonstrate differences between prosthetic feet. Gait analyses of individuals have also been performed to get an idea of what normal gait is.
Grazemore DSS för att prediktera beteskvalitet för mjölkkor :
The aim of this study was to examine if the predictions of the herbage quality in the software Grazemore Decision Support System (DSS) gives a reliable ground for milk production in the north of Scandinavia.
Pasture samples from one research farm (Umeå) and one organic farm (Nordingrå) was analysed on crude protein and organic matter digestibility. The results were statistically compared to the predicted values. Measured and predicted herbage mass was compared and a control if the predictions of milk production improved if the predicted input were replaced by the values from the analysis, was made.
The concentration of crude protein was underestimated by the model on both farms and the relationship between actual and predicted values was poor. Mean Prediction Error (MPE) was 24% and 31% respectively.
Uppnår sjuksköterskestudenter lärandemålen?
Objective: To see if nursing students believe that they have acquired the knowledge that the Higher Education Ordinance demand and if there is any difference between the theory learned at the University and the clinical reality in which students receive their practical training. Method: The method is quantitative and is divided into two parts, one in which the authors describe how the questionnaire was developed and how validity was strengthened. In the second part, the authors describe how the data analysis was made and how reliability of the result was strengthened. Result: The result shows that the students felt that they have achieved most of the objectives of learning demanded by the Higher Education Ordinance. But some objectives are perceived as not at all or only partly achieved.
Terms and conditions (villkor för orderläggning) : En fallstudie på Ericsson AB i Gävle
This final thesis was performed at Ericsson in Gävle between April and June of 2008. Ericsson is a world leading manufacturer of radio base stations (RBS), which handles mobile phone traffic with 2G and 3G technology. The main purpose of this study is to examine if two different types of products (RBS and site material) should have different terms and conditions, today the terms and conditions are the same for both types. During the course of our study we have tried to think of the terms reliability, validity and generalization. The intention in doing that was to keep the thesis at a high academic level. To name an example of this we have tried to keep our minds at an objective level during the interviews and informal conversations.
Lokala styrelser inom grund- och gymnasieskola: Brukarstyrelser och deltagardemokratiska möjligheter och utmaningar: en teoriprövande studie
The question of direct citizen participation in politics and administration is a contestable one. Its proponents claim that it has positive consequences even for the more "traditional", representative democracy, since participation leads to an increased political knowledge and increased political interest, and thus creates a revitalised democracy. Critical voices have however been raised to the validity of this claim. Critics have also pointed out direct participation as problematic, because it leads to problems of political inequality: a difference of political influence between ? on the one hand, the citizens participating directly and those that restrict their political participation to voting, and ? on the one the other hand ? between the institutions, for example schools, that employ, and don?t employ this method of direct citizen influence.In this essay, these two points of criticisms are tested in the context of user-boards in elementary and secondary schools.

Politics, economics and culture", Held, Mc Greew, Goldblatt and Perrton focuses None Governmental Organizations as important actors in the globalized world of today, with increased opportunities to influence and affect the politics. The aim of this paper is to investigate the opportunities for associations for PLHA in Tanzania and Uganda to affect in the national level of politics.
Programvarustöd för hot-, risk- och sårbarhetsanalys
This report describes a final thesis done during the spring of 2008 as part of the bachelor degree in computer engineering degree at the School of Engineering in Jönköping.The client is working in the consulting business and is involved in, amongst others, work regarding information security. Within this field they perform so called Threat, Risk and Vulnerability assessments. Today these assessments are done by a predefined method, but many details are controlled by the person documenting the project. A wish was made that the implementation was standardized, it should also ease the task of estimating the need for time and money. The solution for this seems to be a software tool.
Aktieägaravtalets giltighet mot tredje man : Kan laganalogi göras mot sakrätt och skiljeavtal vid partssuccession?
Trots principen om avtalets subjektiva begränsning kan det finnas skäl till att utöka ett aktieägaravtals verkningar mot förvärvande tredje man för att skydda beaktansvärda intressen. Då rättsläget är oklart är det av intresse att undersöka huruvida en tolkning med laganalogins hjälp mot sakrättens samt skiljerättens område kan klargöra rättsläget.För att ge läsaren tillräcklig bakgrund för analysen beskrivs rättsläget vad gäller aktieägaravtal och de bakomliggande teorierna rörande den analogiska tillämpningen. Därefter analyseras undantag till avtalets subjektiva begränsning, varefter en diskussion följer där frågan huruvida analogier kan dras besvaras.Resultatet av denna framställning är att en analogisk tillämpning kan göras mot de två undersökta rättsområdena, dock endast i begränsad utsträckning vad gäller skiljerättens område. En kombinerad applicering av möjliga analogier från sakrättens och skiljerättens områden på aktieägaravtal leder till ett resultat där aktieägaravtalets bundenhet mot både förvärvande tredje man samt kvarstående parter klargörs..
En jämförelse mellan individers självuppskattade livskvalitet och samhällets hälsopreferenser : En paneldatastudie av hjärtpatienter
Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.
