Från ett användarperspektiv : underlättar use case kommunikationen angående krav och behov i kravhanteringsprocessen?

Examensarbetets frågeställning berör användarnas medverkan i Requirements Engineering (RE). Under RE-fasen skall samtliga krav på det kommande systemet tas fram från intressenterna. En viktig intressentgrupp i kravutvinningsarbetet är de kommande användarna av systemet. Resultatet av RE-fasen är en viktig faktor som påverkar hela den fortsatta utvecklingsprocessen samt hur lyckat det slutliga systemet blir.Detta examensarbete innebär en undersökning av vad användarrepresentanterna anser om use case-modelleringen i RE-processen. Undersökningen har påvisat att användarrepresentanterna är positiva till use case-modellering som arbetsmetod för att kartlägga kraven.

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.

If they say why? Tell'em that it's human nature

My working process is craft based and influenced by devotion for the textile material and techniques, but the concept is just as important. I mainly do sculptural objects where I treat fascination, frustration and disgust for the human body from a personal perspective. I am also deeply fascinated with Michael Jackson; an iconic figure that I adore above all else. A man with an inner musical ability, dedicated his entire life to tame and signify it through his body. My master work is an investigation where I look upon similarities and connections between my fascination with the body and the admiration and fascination with Michael Jackson.

Värdering av katastrofers miljökonsekvenser

When a disaster occurs the main focus is on the loss of human lives. Here the environmental effects have been in the centre of attention. This work has had two main purposes. The first one was to formulate attributes, variables that together present a complete picture of the consequences that an event has had on the environment. The other main purpose was to investigate how people value the impact that a disaster can have on the environment.

Tillämpning av Unified Process och Design Patterns vid integrering av system

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.

Kvarteret Flaggskepparen, Industriellt byggande för offentligt ägda bostäder -En fallstudie i samarbete med NCC Komponent och MKB

The primary focus of this Master thesis is to study how industrial house building can be implemented during production of rental flats under the terms of public procurement. In order to determine a suitable working process as well as presenting a possible architectonic result of the process, a case study is carried through.A housing projekt is designed on a site i Malmö, where the commisioner is MKB Fastighets AB and the contractor is NCC Komponent with the industrial building system NCC Komplett. The focus of the design is to accomplish high quality apartments to a resonable price, as well as solving the overall scheme for the site.The housing projekt, Kv. Flaggskepparen, built on the consept of a single house model, used to handle the entire site, shows that the building system is well suited to accomodate the commisioners demands.In order to reach the best possible architectonic result with the building system, cooperation initiatded in an early stage of the process is neccesary.A model is proposed to handle the situation under the terms of public procurement. The model suggest that the geometrical design is mainly carried out after inquiry and that architectonic qualities should mainly be defined in a non geometrial way for inquiry..

Utveckling av en Multi-Zonsmodell för NOx Bildning i Diesel Motorer

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

Koning av båtmaster : Undersökning av möjligheter till effektivisering

Koning av båtmaster görs i dagsläget med höga kassations- och arbetskostnader. De huvudsakliga orsakerna är svåra inställningar och varierad efterfrågan, en annan orsak är att tillverkningen är hantverksmässig vilket ger lågt fixturutnyttjande.I takt med att nya masttyper börjat konas kommer arbetskostnaderna minska relativt intäkterna givet att de nya volymerna kan hanteras med nuvarande bemanning. Detta förutsätter högre produktivitet i fixturerna.För att anpassa koningen mot en högre produktionsvolym och lägre kassationskostnader krävs åtgärder. Ett viktigt åtgärdsförslag för minskade kassationskostnader är standardisering av skenornas krökning. För tidsbesparing är åtgärden förspänning av master den enskilda åtgärden med störst påverkan.Tillverkning av master varierar kraftigt med säsong, där vår utgör topp medan vintern utgör dal.

Könsroller och Härskartekniker i Twilight : (re)produktion av patriarkalgenusstrukturer genom smäktande kärlekshistoria?

This essay aims to describe and problematize gender roles and master suppression techniques in Stephenie Meyer?s Twilight Saga. This is done in order to enable me, in my future profession as a teacher, to start an emancipatory discussion in class where pupils can become conscious of different ways of reading the love story. I will use the following two research questions to fulfil the purpose: 1) investigate which gender roles that appears in the book?s main characters Bella and Edward and 2) which master suppression techniques that colours their relationship.To answer the questions gender theory and ideology-critics are used.

Chinese Remainder Theorem

Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.

Bibliotekariernas arbete vid de publika datorerna ? Vad ingår och vad bör ingå i det arbetet?

The purpose of this master thesis was to study the librarians?assignment at the public accesses computers, especially howthe librarians perceive what their task is and what their taskshould be.In order to answer these questions a series of ten qualitativeinterviews ?inspired by the phenomenographic approach ?was conducted with librarians who were employed at smallpublic libraries in municipalities with 5 000 - 25 000residents in Sweden.The conclusions in the master thesis were that librarianshave both similarities and differences in how they perceivetheir tasks at the public computers. The most essential taskwas helping the user with information seeking. Thelibrarians also perceived that it should be included in theirduties to help users with the technical/practical issues at thepublic computers. Competence, time and assets were finallythree outlying factors which affected in what extent thelibrarians were able to help the users..

Sjuksköterskors uppfattningar ominformationssäkerhet : en kvalitativ intervjustudie

Inom hälso- och sjukvården hanteras känslig patientinformation. I framtiden kommer alltmer information att lagras elektroniskt och därmed bli mer lättillgänglig. Användarna av informationssystemen kan vara en säkerhetsrisk. Metoderna som används vid intrångsförsök inriktas alltmer på att involvera människor istället för att enbart använda sig av teknik.Syftet med detta arbete är att undersöka användarnas upplevelse och medvetenhet om icke tekniska hot mot informationssäkerheten för digitalt lagrad patientinformation.Datainsamlingen genomfördes i form av kvalitativa intervjuer med sjuksköterskor anställda på ett sjukhus i västra Sverige. Resultatet visar att det allt överskuggande upplevda hotet var intrång och förlust av sekretess i den elektroniska patientjournalen.

Studenters användning av akademiska tidskrifter: en källanalys av BandI-studenters magisteruppsatser 1999-2001

Previous research indicates that the academic journal in many cases is the most valuable and important source of information in scientific work. The aim of this study is to investigate students usage of academic journals in comparison to their usage of other document types, as illustrated by the citations given in LIS students master theses 1999-2001. By comparing the students use of LIS journals with the use of LIS journals by international scholars we also wish to examine whether students and scholars use the same journals in their work. The international scholars are represented by references given in LIS journals 1999-2001, recorded by the citation index Journal Citation Reports. Questions: 1.

Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter

AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.
