In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.

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.

The Swedish field of digital X-ray imaging has since several years relied heavily on distributed information systems and digital storage containers. To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback?the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.

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..

Förändringar i affärsvärlden leder till att företag idag ständigt ställs inför nya utmaningar. Samverkan mellan affärsverksamheten och IT har därför blivit en viktig aspekt inom organisationer. Företag står inför problemet att hantera sina komplexa affärsprocesser, information och infrastruktur, relaterat till att IT bör ge maximala värden för affärsprocesserna. Det för att verksamheterna ska vara med i spelet bland de konkurrenskraftiga organisationerna, vilket leder till en av anledningar till att företagen kommer i kontakt med Enterprise Architecture (EA). EA kan ses som en helhetsbild av organisationen och dess information, applikationer och infrastruktur.

Denna studie vill undersöka om koloniala strukturer genomsyrar den senaste i raden av Star Trek-serierna, Enterprise. Med utgångspunkt i äldre forskning om just koloniala strukturer i Star Trek kommer en jämförelse göras om Enterprise först och främst har dessa strukturer och om så är fallet, göra en jämförelse med de andra serierna.Det postkoloniala forskningsfältet tillsammans med ett strukturalistiskt och post-strukturalistiskt tillvägagångssätt som innefattar semiotik och diskursanalys används för att kunna peka på hur de koloniala strukturerna genomsyrar serien.Analysen, som bland annat innefattar besättningens inbördes hierarki, hur andra främmande raser ser ut och vilka egenskaper de har och hur mötet går till med andra kulturer, visar att de koloniala strukturerna fortfarande genomsyrar Star Trek. Enterprise skiljer sig dock från de äldre serierna på ett sådant sätt att det koloniala tar mindre plats, bland annat seriens handling och även hur alla besättningsmedlemmar är med och skapar seriens handling..

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.

Today every organization is committed to some kind of environmental scanning in order to get necessary knowledge of the world around them. The acquisition, organization and storage of information in combination with a strategic use, is today an important factor for a successful organisation in any sector of our society.In this Master thesis I have studied how an organisation such as The Confederation of Swedish Enterprise (Svenskt Näringsliv) handles its information resources. I have also looked at the flow of information within the organization. The Confederation of Swedish Enterprise is Sweden?s largest business federation representing 50 member organizations and 55 000 member companies.

Background: Investors use companies? credit ratings as a base in their buy and sell decisions. Companies? credit ratings are also used as indicators of safety in the legislation. This means that credit rating agencies have an important role in the society because they communicate the company?s credit rating to investors and other actors in the society.

The aim of this thesis is to define digital library, and to investigate a relation between the construction of a digital library and user needs. The main questions to be answered are: 1 What criteria was used when constructing a digital library, particularly concerning issues like purpose, function, design, supply, services, resources and future development of the digital library? 2 How do the digital library system designers and system builders criteria correspond with those of postgraduate researchers? And what factors affect the use? A digital library is an enterprise that gives access to information stored digitally and directly available on the net. The crucial is that the enterprise has a control over collection of information and responsibility to make it available to a defined group of users. In order to investigate the relation between the construction of the digital library and user needs, I have interviewed five key people involved with the work with the digital library and twenty postgraduate researchers from the Gothenburg University.

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.

This essay is about testing the validity of an article written by Jonas Löwgren, called The use qualities of digital design. The study we have executed is about testing the featured qualities of digital design in the article on two search systems located in the library of Stockholm University and Södertörn University respectively to see how they are able to be applied on search systems. To acquire the information for the study, we handed out a written inquire among users of those systems. The result of this quantitative study shows us that many that five of Löwgrens qualities is likely to be present on the systems. Our conclusion is that five of these are appliable on search systems.

Det går att se på en systemutvecklingsmetod på olika sätt. Dels kan man studera den utifrån dess beståndsdelar, och dels kan man studera de processer i utvecklingsarbetet som leder fram till slutresultatet. I detta examensarbete diskuteras en del av de kognitiva krav som ställs vid inlärning av en systemutvecklingsmetod.Inom ramen för en litteraturstudie diskuteras vad som är viktigt att lyfta fram när en systemutvecklingsmetod ska presenteras och vilka inlärningsproblem som finns i samband med detta.Rapporten innehåller även en fallstudie där en systemutvecklingsmetod (Enterprise Knowledge Development) presenteras i HTML-format i en så kallad Electronic Guide Book. Examensarbetets bidrag till EGB består i att ge exempel på hur valda delar av EKD kan presenteras i HTML-format..
