Kommunala webbplatser för alla eller några? : Kvalitativa intervjuer med webbansvariga i tio sydsvenska kommuner

There is a need for examining the accessibility of public web sites and for several reasons. First, public organizations possess considerable amounts information of interest to its citizens and which ought to be easily accessible. Secondly, international and national guidelines for web publishing support the different types of requirements experienced by web users and, in particular, with regard to accessibility for people with disabilities. The thesis examines the design of public web sites from two different aspects. Web sites can be built up and structured from the management view of the public organization, or, they can be constructed with a view to user needs and requirements.

Etnicitet och kön :  Påverkar grupptillhörighet bedömningar av korrekthet i centrala meningar från ett vittnesmål?

Syftet med denna studie var att studera möjligheten att bedöma korrekthet i vittnens utsagor beroende av deltagarnas grupptillhörighet. I studien ingick 120 deltagare som antingen fick se en film med vittnesmål från fyra vittnen med enstaka centrala meningar eller läsa en text med samma meningar. De viktigaste mätningarna i denna studie gjordes efter signal detection theory (SDT). Resultaten visade att deltagarna inte skattade mycket över slumpnivå och ofta till och med under slumpnivå i sina bedömningar. I en hopslagning av betingelserna (text/film) visade analyserna att män generellt var signifikant sämre än kvinnorna på att bedöma vittnesmål, men att kvinnorna gör fler falska alarm än männen i bedömningen av textversionen.  De funna könsskillnaderna i hur vittnesmål bedöms diskuterades..

Förstudie för kvalitetssäkringav glidande förband vid Hissmoforsvattenkraftsstation : -Specifikt för aggregat G6 och G7

Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..

Användbarheten i Business Intelligens-system : Utvecklingen av användbarheten och funktionaliteten i ett webbaserat BI-system

The purpose of this study is to evaluate an existing user interface. The company in question has a web-based user interface (available through logging in via their website), but they are interested in making the process of using the interface more convenient and the interface more accessible, so that users without a background in computing can properly manage the interface. At the same time they want to apply additional functionalities in order create and to manage increased traffic on the company?s website. For this reason it is important to take into account the issues involved in human-computer interaction (HCI) as well as aspects of cognitive psychology in order to make the tool and the web interface more usable, more motivational, and therefore more efficient and professional.

Peer-to-peer som företagslösning

Problemområde: Idag är användandet av peer-to-peer (P2P) - applikationer såsom KaZaa, ICQ och Seti@home utbrett bland privatpersoner. Användningen inom företag är dock ännu i sin linda. Vi kommer därför i den här uppsatsen utreda om ett eventuellt införande av P2P- teknik i ett företagsnätverk ger några fördelar jämfört med en klassisk Client/Server-lösning. Hypotes: Arbetet bygger på hypotesen: ?En P2P-lösning ger fördelar för företaget jämfört med en Client/Server-lösning? Genomförande: För jämförelsen mellan P2P och Client/Server definierades och jämfördes fem områden: Säkerhet, Användbarhet, Tillgänglighet, Bandbredd samt Utrustningskrav. Slutsats: Inom områdena Användbarhet och Tillgänglighet ger en P2P-lösning klara fördelar, däremot inom områdena Säkerhet och Bandbredd visar Client/Server- lösningen istället klara fördelar. Området Utrustningskrav är oavgjort då det inte finns någon märkbar skillnad på lösningarna. Säkerhetsproblemen är P2P-teknologins akilleshäl och det problem som är mest troligt att stoppa stora investeringar i framtiden om det inte löses. Slutsatsen av vår jämförelse blir sålunda: För ett företag som redan har ett existerande Client/Server-nätverk är det inte någon idé att helt byta system, däremot kan det vara av intresse att introducera en applikation som möjliggör skapandet av så kallade Virtuella Nätverk. För ett helt nytt företag kan skapandet av ett P2P-nätverk vara ett väl så intressant alternativ till Client/Server.

Brothers in arms or partners in crime? A study of the gap between EU and USA in the cooperation against global terrorism.

In this thesis I analyse and discuss what impact the 2003 U.S lead intervention in Iraq, had for the cooperation against global terrorism between the European Union and the United States. Six years have passed since the Bush administration decided to go on with the intervention, even though they did not have the necessary UN mandate. Due to unsuccessful argumentation in favour of the intervention by the Bush administration, the world got divided. George W. Bush reference to a ?war on terror?, which passed almost unnoticed by Americans, rang alarm bells in many European countries.

Kostnadskalkylering på en förpackningsavdelning

This degree project is based on identifying and allocation of costs in a packaging section at Electrolux Distriparts in Torsvik.The purpose of this thesis is to identify the costs that emerge when packaging different articles and show how the costs are allocated. The report also contains improvement suggestions about how the company can use the current computer system more efficient.The methods that have been used in order to approach the problem and the collection of information have mainly been literature study, interviews and observation.The work started with answering the questions; which expenditure cost and direct cost exist in the section, how can they be allocated, if improvement can be done and how the flow of information is supposed to happen.In order to answer the questions we used our former experience and the knowledge we achieved by reading literature, interview relevant persons in the company and observations carried out in the section.Through our studies, we came up with an Excel file, which is the groundwork for a template that can be used by the company in different occasions depending on the situation and need. It is important to remember to modify the template if the presumptions change. In the template, we have identified the different kind of costs that emerge when packaging different articles and we have also allocated the costs. In addition formulas and estimations that are necessary for the cost calculation are presented.The work consisted in making the groundwork for a template.

Studenters mobilanvändning under föreläsningar : En studie om hur studenters koncentrationsförmåga påverkas av mobilanvändning under föreläsningar

In Sweden there is a long ongoing discussion about computer and cellphone usage during lectures in school. The discussion has mainly covered elementary school up to college students, but this topic is at least as relevant for university students. Today cellphones are so advanced; you can do everything with one that you previously only could do with a computer, the difference is that everyone is carrying one with them all the time. This study shows how concentration during lectures is affected by the cellphone accessibility and usage. With this study we want to find out how university students perceive cellphone usage affects their own concentration during lectures.

Den Moderna Webben: Kan HTML5 konkurrera med traditionell programvara?

Vi ser en förändring i hur vi använder applikationer. Från att tidigare varit associerat till en dator och begränsat till ett par operativsystem finns de numera överallt. Fler plattformar innebär att man måste utveckla en applikation till var och en av dessa. Detta gör att utvecklingstiden och kostnaderna ökar och efterfrågan av crossplattformlösningar i form av webbapplikationer har därför ökat. Vi tittar närmare på hur det går att använda sig av HTML5, och övriga tekniker som en modern webbläsare har integrerat stöd för, för att utveckla webbaserade applikationer. Vi tar reda på om det finns några hinder eller begränsningar i detta och om det finns några fördelar i att använda webben som plattform. Resultatet indikerar att med de nya tekniker som är på ingång kan man utveckla webbbaserade applikationer med prestanda motsvarande Java eller C#.

Analys av off-design prestanda för ett absorptionskylsystem

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

Utveckling av metodik för varningssystem i trafiken

Syftet för denna uppsats var att utveckla metodiken för utvärdering av varningsljud i förarmiljö. I undersökningen används syntetiskt framställda ljud. En likhetsskattning av ljuden utfördes och korrelerades gentemot hur väl ljudet passade in för de olika trafiksituationerna. Trafiksituationerna består av att ett bakre fordon accelererade mot ett främre fordon och framkallade ett hot för kollision under en viss tid. Det var ett ljud som korrelerade högt, vilket var ett entonigt alarm.

Digitalisera loggboken : En analys av utmaningarna med att utveckla IT-stöd för kunskapsintensiva verksamheter

Failed system development projects are a common sight within the IT-industry. During the last ten years we have seen several more or less disastrous high profile projects being reported in the news. One aspect that might hold some of the responsibility for these failures is the fact that more organisations are knowledge intensive which makes their work processes difficult to capture in computer systems. How requirements engineering is handled becomes even more important in these cases, where processes are unpredictable and rely on individual judgement and knowledge. In this study we have examined the challenges of developing systems for knowledge intensive businesses through a method of qualitative case study of a university laboratory.

Larmbolagets webbplats : En studie om skapandet av en tillgänglig och användbar webbplats

This paper accounts for the work with a website for a company whose real name will not be disclosed in the text of this paper. Instead, they have been assigned the fictitious name Larmbolaget, which can be translated as ?The Alarm Company?.During our work with Larmbolaget?s website, we consulted a selection of accessibility guidelines from the Web Content Accessibility Guidelines (WCAG) 2.0, developed by a working group within the World Wide Web Consortium, as well as a number of design principles and heuristics outlined in this paper. We also conducted several usability tests on users from our intended target group. All the measures taken were an effort to ensure that Larmbolaget?s website be as accessible and usable as possible.Our conclusion is that the resulting website does comply with the accessibility guidelines and design principles described in this paper, and thus we consider it to be accessible and usable to a wide range of users, including those with disabilities..
