Biblioteks- och informationsvetenskapens överordnade identitet : ämnets betydelse för studentens yrkesinriktning
Library and information science (LIS), being a research area characterized by theoretical discord and definition disarray, provides an interesting field of inquiry. Its content, boundaries, scope and superior identity are not clearly stated. This Master s thesis focuses on a thus far unexplored perspective on the discipline: a conceivable statistic and causes- and- effect relationship between the LIS students appreciated identification with the superior identity of the discipline, and the chosen vocational direction within the field. This relationship is examined through testing a working hypothesis on the results of a major quantitative questionnaire survey. The theory behind our research derives mainly from Thomas Kuhn and Richard Whitley.
Verifikation av verktyget aspect analyzer
Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.
En indirekt metod för adaptiv reglering av en helikopter
When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
Erfarenhetsrapportering vid Forsmarks Kraftgrupp AB : Utvärdering av erfarenhetsåterföringsprocessen samt utveckling av ett systemstöd
Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.
Modellering av indunstning på Södra Cell Mönsterås
Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.
Implementering av multivariabel reglering i DCS-miljö
Inom processindustrin finns en etablerad reglerhierarki där basreglering sker med PID-regulatorer och där avancerad, multivariabel styrning sköts av MPC-programvara. Steget mellan dessa två nivåer kan upplevas som stort. För mindre och snabba multivariabla processer undvikes helst en multivariabel ansats, med försämrad reglering som följd. På Preem AB har detta upplevts som ett problem. Syftet med examensarbetet har varit att utveckla en alternativ, multivariabel styrstrategi för en process med ett mindre antal reglerstorheter som interagerar.
Utveckling av generell testklient för Nordic Growth Market
Development and accuracy tests of advanced exchange trading systems require well adjusted tools for testing. Aptness of these tools are probable to have a major impact on identification of bugs and verification of new functionality. Identifying erroneous parts and bottlenecks of the trading system is of outmost importance for the exchange as a whole since stability and correctness are two of the determinant factors its viability is measured by. This paper covers how this test-tool was created and the motivation behind the design choices made. The tool was created with the goal to be broad enough to cover the majority of cases that could arise, fast enough to be able to test the trading systems speed limitations (i.e.

Designlösningar i ett affärssystem ur ett kognitionsvetenskapligt förhållningssätt
The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

Skanskas säkerhet på arbetsplatsen : Personlig skyddsutrustning
This degree projekt deals with Skanska´s safety at the construction site with focus on personal safety equipment. The purpose of this dissertation is to examine how the rules of personal safety equipment are applied and experienced at Skanska´s construction sites.In October 2004 Skanska started a projekt to make the construction sites more safe. With use of a questionnaire we have made a survey at different construction sites. 80 questionaires have been handed out to Skanska´s employees in the southeast region. While they were handed out we conrolled if the employees at Skanska´s construction sites used head protection, easy visible clothing, safety shoes and identification cards.The result of the survey shows how the rules are applied.
Gage R&R studie på mätutrustning för förpackningsavstånd
The aim of the thesis is to analyse and understand resolution, repeatability and reproducibility of the measurement system for package distance. The measurement system for package distance is already in use, no Gage R&R has been performed on the system and before spreading use of the system the quality of the system has to be understood and approved.
