Ontologi/taxonomi för att stödja integration mellan KBE-applikationer
Som nämns i titeln till examensarbetet är målet att integrera olika knowledge-based engineering (KBE) -applikationer till ett nytt IT-stöd. Med mål i examensarbetets kontext avses att skapa en begreppsmodell genom att tillämpa ontologi och taxonomi som en teknik i en begreppsmodellering. På detta sätt kan ett gemensamt vokabulär skapas. Syftet med vokabuläret är att presentera en samstämmig förklaring till olika begrepp samt relationerna dem emellan. Därav kan tolkningen av ett begrepps betydelse minimeras och på så sätt undvika "språkförbistring".
Att arbeta med Scrum : Påverkan på arbetslag, kommunikation och social miljö
Systems development methods has always been an important part of the systems development process. It affects not only the product, but also the organization itself. Today more and more companies are abandoning the more rigid traditional methods for the more flexible agile ones. A transition like this is bound to affect the product and the organization, but in what ways? Is it a difficult transition to make, and how does it affect social environment and dynamics? Does it change how people communicate information to each other? This study was conducted at a local branch of a larger international IT-company.

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.
Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.
Att katalogisera en specialsamling med hjälp av TEI: En metodprövande studie utförd på Swedenborgsarkivet i Kungl. Vetenskapsakademien
In this thesis, the TEI (Text Encoding Initiative) encoding scheme is investigated as a system for storing metadata about manuscript material and 18th century first prints in the Swedenborg Archives at the Swedish Royal Academy of Sciences. The aim of the study is to test the functionality of TEI as a metadata system in cataloguing a special collection. Some criteria of functionality are formulated, and examples of encoded catalogue entries are described and analysed. It is demonstrated how descriptive metadata have been registered within the TEI header, while structural metadata have been recorded within the text element of the TEI file. On the whole, TEI is considered to be a functional tool that matches the present purposes.
Konstruktionen av en "invandrare" - I mötet mellan tillskrivandet och behovet av en kollektiv identitet
The way society categorize different people into groups is problematic in the sense that the categorization can seem stigmatizing and have social consequences for those being categorized. Immigrants are one of those problematic categories.The following essay studies this categorization of ?immigrants? based on a governmental investigation of structural discrimination that took place in 2002-2008. The aim is to study the use of the category ?immigrant? and the consequences that follows such a categorization.
?Jag ville faktiskt hoppa av programmet? - Erfarenheter av rasism diskriminering bland socionomstudenter
This study investigates and analyzes experiences of discrimination and racism among social work students, focusing on how these issues occur between peers rather than through hierarchical dynamics, such as interactions with faculty. The research aims to shed light on the academic challenges faced by students with foreign backgrounds, as defined by Statistics Sweden (SCB), particularly those who experience discriminatory practices and behaviors within the academic environment. The study adopts a qualitative methodology, utilizing semi-structured interviews to explore the lived experiences of these students. Participants were selected based on their enrollment in social work programs and their identification as having a foreign background. Data was analyzed thematically to uncover recurring patterns and insights into the participants' experiences.
Att ständigt vara beredd på det okända: En studie om hur charterresebranschen i Sverige förbereder sig för, och hanterar krissituationer
In the world of today, crises and crisis situations are inevitable parts of an organization?s everyday life and it is important for the organization to be prepared for these crises. The organization and its employees have to be in a constant state of alert and they should also have an organized plan for what they will do when (not if) the crisis occurs. The charter tour industry has during a long period of time been active in the global market. They serve thousands of travellers every day and it is the responsibility of the companies within the industry to make sure that their customers are safe and that crises can be prevented, or at least be handled.
Nyttorealisering av affärssystem : Microsoft Dynamics NAV vid Statoilstationer i Sundsvall och Hudiksvall
Det övergripande syftet med denna undersökning har varit att undersöka vilka nyttor som förväntas vid implementeringen av ett affärssystem, vilka som realiserats av systemet samt om dessa nyttor har mätts eller värderats på något sätt för att möjliggöra uppföljning av investeringen. Studien har genomförts med en kvalitativ metod och semistrukturerade intervjuer. Respondenterna som har intervjuats arbetar med ett affärssystem i det dagliga arbetet på olika Statoilstationer i Sundsvall och Hudiksvall. Därför har även huruvida de upplevda nyttorna är beroende av driftsform på stationerna, bolagsdrivna stationer och franchisedrivna stationer undersökts. Respondenter från Svenska Statoil har också intervjuats för att få en bild av hur de ser på detta eftersom de tog beslut om att införa systemet på samtliga stationer.

Kampen mot ?machismo?! -en studie av Forum Syds lokala samarbetsorganisationers jämställdhetsarbete med män i Nicaragua
Equality is a central aspect within development work. All development work is expected to be influenced by a gender equalty thinking, and these directions are distributed by the Department of Foreign Affairs, through Sida to Forum Syd and down to the very grasroot level, through Forum Syds local cooperation organisations. The essays question of research is a reflection over empowerment, with other words how international organisations influence other societies understanding of the society dynamics. This aspect triggered my interest for the subject, aswell as the link between aid, equality and men, and how these factors are in need of eachother. My study is mainly build on theoretical starting points, and not on earlier studies.
Starkare i samhället - Om invandrarföreningar som en social resurs för politisk integration
This paper examines the consequences of membership and participation in immigrant associations on individual immigrants? political integration and indirect political participation with reference to Swedish society. The theoretical underpinnings consist of a social structural outlook on social capital, combined with the Civic Voluntarism Model, both of which focus on the potential role of social networks for moving people into political action. After a presentation of parallel qualitative data over the experiences of individual members in a Finnish and Bosnian-Hercegovinian organisation, it is suggested that immigrant associations support the political integration of their members into the host society. Firstly, the case studies indicate that members of immigrant associations gain the opportunity to augment their civic skills, which is a significant prerequisite for political participation.
Beräkningsmodell för massbalanser för Slottshagens reningsverk
In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..
