Control systems have more, than one, relation to each other..
Energivinst vid hybridisering av hydrauliskt system
Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.
OSE och Linux : En studie om prestanda
There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..
Konsekvensutredning inför införande av koncerngemensam systemplattform : Vad skulle det innebär att införa SAP på KSU, Kärnkraftssäkerhet och Utbildning AB
The implementation of large IT-systems is a complex area where many aspects have to be taken into account.KSU, Kärnkraftssäkerhet och Utbildning AB, is a small company in the Vattenfall group that is increasingly being urged to implement SAP, one of the largest ERP-systems on the market. Vattenfalls purpose with SAP is to centralize certain processes within economy that are common to all the companies in the group, this to gain benefits with economics of scale. However, KSU is not convinced that SAP is a suitable system and that the common processes apply to them.The purpose of this degree project is to investigate if SAP is a suitable system and if KSU will benefit from a transition to SAP. Three perspectives were applied to further specify important areas of the main question. From a technical point of view KSU:s demands on a system was mapped against SAP.
Electrolux och patenten. En studie av Electrolux patentstrategiska agerande 1950-1970.
Application Lifecycle Management (ALM) is a genre of computerized systems which allows system development corporations to efficiently and more easily manage, maintain and handle the applications lifecycle. These ALM systems have a wide variety of tools which can be integrated to enable and support collaborative work, while they act at the core of the organisation. Todays ALM systems support flexible system development methods throughout the entire development process. This paper focuses on a case-study of a Swedish business- and technology corporation and their use of two ALM systems with an aim to unravel the differences between these systems and their functionality to serve as a basis for decision making regarding their utilization of best practice with their ALM-Systems. Meanwhile we studied their approach to ALM systems to see if they were using them according to the initial idea of ALM systems.
Analysis of Intent Specification and SystemUpgrade Traceability
The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.
(O)kritisk informationskompetens? : En utvärdering av undervisning i informationskompetens inom högre utbildning
The purpose of this thesis is to examine the benefit of information literacy instruction in two student groups at Kristianstad University, in relation to development of critical information literacy and within the boundaries of the educational goals. This study takes on a critical information literacy perspective that combines critical pedagogy and standards for information literacy in higher education. Two methods have been used for data collection: interviews and questionnaires. According to the results of the study the information literacy instruction provided by the Kristianstad University Library is important and useful for the students in their academic studies. It also becomes clear that the information literacy differs between the two groups as a consequence of the varying information literacy instruction received by the two groups.

Den manliga heterosexuella normen En analys av SAB-systemet utifrån ett feministiskt och queerteoretiskt perspektiv
The aim of this Masters thesis is to conduct an analysis of the Swedish classification system the SAB-system from a feminist and queer theoretical perspective. The theoretical framework of the study is feminist and queer theory as well as theories from Library and Information Science, mainly classification theory. The study takes its departure from the idea of classification systems as social constructs, reflecting their time, place and society. Paul Ricoeurs critical hermeneutics is used as methodological guidance. This gives room for a critical perspective in the interpretation.
En väg till förbättring : Systemanalys ur ett användarperspektiv
In almost every workplace today IT-systems have strong and significant roll in theeveryday work. It is therefore important that the systems have a good functionalityand that they work as an aid for the users. This thesis aims to study the systems atthe company Telge Nät and to analyse them from a usability perspective. By using thisperspective it has been obvious how difficult it is to make improvements on usability,once the system is in place. Even other larger improvements of the systems aredifficult to make at this stage and this is something that the users are aware of.

Vinstdelning: En studie i hur affärsjuridiska advokatbyråers vinstdelningssystem är uppbyggda och hur valet av vinstdelningssystem påverkar organisationen.
In the last couple of decades, corporate law firms have rapidly grown to become both influential and highly profitable corporations in the business world. Today, the largest law firms are assumed to bear far greater resemblance to large and often multinational public limited companies than the small businesses generally associated with legal services. However, one interesting specific set them apart from the majority of other companies; the partnership and its interrelated profit sharing. The aim of this study has therefore been to investigate partner compensation systems in corporate law firms and further examine what implications chosen compensation systems have on the organizations. Using a multiple case study, including 7 of Scandinavia?s largest and most well known law firms, the results show that partner compensation systems are highly individual and the critical question is whether to employ seniority based or performance based compensation systems.
Att dela eller inte dela? : Vad som möjliggör respektive förhindrar produktdelningssystem
Product sharing systems is recently starting to become a more common phenomenon. Carpools exist in more than 40 Swedish towns and both Stockholm and Gothenburg have established bicycle sharing systems. Other products for which sharing systems have been established throughout Sweden are clothing and tools. From the point of view of the consumer, product sharing systems is a form of consumption which can be placed somewhere in between renting and privately owning a product, where the consumers usually pay a membership fee or a monthly fee to have access to the products whenever they need them. The concept is relatively new, and there are many products for which product sharing systems do not exist.
