Legacy systems: hur kan organisationer förhålla sig till föråldrade system?

Tanken bakom examensarbetet var att undersöka huruvida de äldre system som finns i bruk ute i organisationer idag uppfattas som ett problem samt vad som i sådana fall görs åt problemet. Ett flertal författare har under åren förklarat hur förändringar i system leder till en försämrad struktur vilket förr eller senare orsakar ett försvårat underhållsarbete av system. För att ta reda på hur väl litteraturen stämmer överrens med svenska organisationer så har vi intervjuat fyra respondenter för att få deras syn på problematiken. Denna har sedan jämförts och diskuterats mot de premisser vi funnit i litteraturen. Det har framkommit att det litteraturen inom området menar, stämmer till stor del med det våra respondenter berättat.

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.

Att bli subjekt i sin egen historia : En studie i Alice Lyttkens Flykten från vardagen och - kommer inte till middagen

Alice Lyttkens (1897-1991) was a very popular author in Sweden during several decades in the middle of the twentieth century. She was most famous for her historical novels. During her first period as a novelist in the 1930s, however, she wrote contemporary fiction, reflecting the situation of contemporary Women. The traditional view of the two sexes as ?complementary? permeated the interwar period.

Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.

Hur förhåller sig kenyanska lärare till föreställningen om barn som besatta av demoner? : Hur några lärare i Kenya resonerar kring barn i behov av särskilt stöd

The purpose of the study is to find out how some teachers in Kenya reason about children in need of special support. To undertake the study the following question are used:How do some teachers in Kenya reason about children in need of special support?The study has been made with qualitative interviews in Kenya. A total of four teachers at primary school level have been interviewed. The decision to do qualitative interviews is made by the opportunity to get as comprehensive answers as possible from the respondents' reason about children in need of special support.Three different kinds of special education perspectives have been used in this study.

Uppvärmningssystem : Ekonomi, miljö och drift

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Mänskliga rättigheter vid en naturkatastrof : En jämförelse mellan Haiti och Thailand

There are three main purposes for this thesis; the first is to distinguish the possible violations that can occur in time of natural disasters. The second is to analyze if there is a correlation between political systems and how the effected country handles the aftermath of a natural disaster. The third purpose is to determine the role of the global community and what responsibility lies with them. The issue is often that the aid becomes the main object for discussion and analysis, but the focus rarely shifts to the effected State. Therefore the focus in this essay is the political system and how they cope with the human rights violations that can occur in a time of natural disaster.

Teknik för en flerskiktadwebbapplikation

The report analyses if some common problems can be avoided by using modern technology. As a reference system ?Fartygsrapporteringssystemet? is used. It is an n-tier web application built with modern technology at time, 2003-2004. The aim is to examine whether ASP.Net MVC, Windows Communication Foundation, Workflow Foundation and SQL Server 2005 Service Broker can be used to create an n-tier web application which also communicate with other systems and facilitate automated testing.

Barn söker i bibliotek ? en kunskapsöversikt

The aim of this thesis is to investigate new knowledge about how children search for library material and which strategies they use, and if the latest research gives any answers whether we should adapt systems and services or teach information seeking in a better way. In this thesis knowledge is understood as research publications but also results from projects in library practise, and studies concerning children 6 to 18 years old are included. The method used is a knowledge survey. We have gathered and evaluated documentation from different sources like citation and reference databases within the field of library and information science. The result implicates that there are, both in old and new documentation, three main search strategies children use in their search for information in a library context; they browse, they search in library catalogues and they use some sort of reference service.

Användarrelaterad energieffektivisering : En studie på länssjukhuset i Sundsvall

Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.

"ADHD vanligt bland unga brottslingar" : En kritisk diskursanalys av hur Aftonbladet och Dagens Nyheter framställer ADHD

ADHD is the fastest growing diagnosis of the last decade and there is an ongoing debate about how ADHD should be understood with a psychosocial perspective opposed to a medical perspective. The purpose of this study was to investigate how a Swedish daily and evening newspaper (Aftonbladet and Dagens Nyheter) portrays ADHD. Further, the study asked whether medical or social explanation is used in the discourse that appears in newspaper articles, how ADHD is described as well as which people are quoted in the articles. In this study we used Norman Fairclough´s critical discourse analysis with the 26 sampled articles which we believe highlight different perspectives on ADHD diagnosis.Our study shows that there are representatives cited in the articles from school, the judiciary and the medical field. However representatives from social work are conspicuous by their absence.

Fastpris med Dynamic Systems Development Method (DSDM) : Fungerar DSDM som projektstyrningsmodell i fastprisprojekt?

Enligt Standish Group är det endast cirka 35 % av alla systemutvecklingsprojekt som avslutas på ett lyckat sätt när det gäller tid, budget och resurser. Inom systemutveckling är fastprisprojekt, där systemets kostnad är förbestämd, allt mer populärt. Dynamic Systems Development Method (DSDM) är en modell för utveckling som fokuserar på fasta resurser och tid med funktionalitet som den flexibla variabeln. Syftet med den här uppsatsen är att se om man kan driva fastprisprojekt med en modell som DSDM på ett sätt som gör det till en bra lösning för både beställare och leverantör.Min slutsats är att det största problemet med DSDM är att få beställaren att godkänna den som projektmodell. Ett annat stort problem är att många projekt med DSDM blir stressiga eftersom tiden är fast.

Lärares genusmedvetenhet : En kvalitativ studie om idrottslärares beaktning av genus i undervisningen

The study is about PE teachers? consideration of gender in the assessment as well as in the selection of lesson content. Semi-structured interviews were employed as method for the data collecting process. Four teachers were interviewed, teachers of PE in elementary and upper secondary school with varied length of professional experience and ages.

Webbsystem för matprisjämförelser

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
