Use Case : en teknik för att representera krav i RE-processen

Detta examensarbete ger en introduktion till Requirements Engineering (RE), kravprocessen i informationssystemutveckling. Det slutliga informationssystemet är i stor utsträckning beroende av en effektiv RE-process. Ett framgångsrikt informationssystem beror på hur väl det färdiga systemet stämmer överens med användarens och andra intressenters behov och förväntningar. Use Case är en teknik som kan användas i RE-processen för att representera krav. Arbetets syfte är att finna de för- och nackdelar som finns med Use Case för att representera krav.

Informationssystem för service av truckar och städmaskiner

This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided.

Utvärdering av kalibreringsmetoder för modväxlande kammare

Vår uppgift var att praktiskt genomföra och utvärdera två kalibreringsmetoder för modväxlande kammare hos Saab Avionics AB i Linköping. En metod som Saab Avionics använder och en metod enligt europeisk civil flygstandard, EUROCAE ED- 14D kapitel 20.6. Uppgiften löstes genom att utföra mätningar enligt de två kalibreringsmetoderna och därefter analysera mätdata i MatLab. Vi hann med att göra Saab Avionics kalibreringsmetod i samtliga mätpunkter som krävdes för utvärderingen, men bara drygt halva kalibreringen enligt europeisk civil flygstandard. Utifrån de mätningar vi gjort kan vi dra följande slutsatser: Båda kalibreringsmetoderna säger att Saab Avionics modväxlande kammare uppfyller respektive krav när den är olastad.

Anonymous ansikten : En undersökningar av några svenska dagstidningars konstruktioner av hackernätverket Anonymous

This study examines how a couple of Swedish daily newspapers construct the hacker network Anonymous, with an aim to discuss its possible effects. The question was: In which ways is the network Anonymous constructed in a few Swedish newspapers?                      26 articles from four chosen newspaper were analysed, but because of many similarities in content, only 10 were chosen for deep analysis. With Fairclough's model of critical discourse analysis as chosen method, constructions varying from the images of heroes to villains were found as a result. The most common construction was that of Anonymous as a threat, which was most often exaggerated compared to what actions were actually described in the texts.

Infiltration av lakvatten från specialceller i bioceller -en effektiv metod för att förhindra spridning av metaller

Deponering är en metod som sedan länge använts för att behandla avfall. Metoden är dock kopplad till en rad miljöpåverkande faktorer, varav produktion av lakvatten är en. I lakvattnet finns bland annat lösta näringsämnen och metaller och dessa kan ge negativ påverkan på ekosystem om de sprids i miljön.Det här examensarbetet syftar till att besvara frågan om metaller i lakvatten kan retarderas genom att lakvattnet från en specialcell infiltreras i en biocell. För att besvara frågeställningen har mätvärden för ett antal kemiska parametrar analyserats på en deponeringsanläggning som ligger i Malmö och bedrivs av SYSAV.Arbetet avser även svara på frågan hur hårt biocellen kan belastas i fråga om hydraulik. Därför simuleras de förväntade uppehållstiderna av vatten i biocellen vid olika infiltrations-hastighet och porositet.För att ge resultaten tyngd har en litteraturstudie avseende deponering, hydrologi och hydraulik, lakvatten och metallers mobilitet i mark och vatten gjorts.Resultatet från litteraturstudien visar bland annat att lakvatten produceras genom att nederbörd perkolerar genom avfallet.

Utvecklingen från traditionell ekonomistyrning till verksamhetsstyrning : En studie inom ekonomistyrning

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

Mångfaldens gemenskap? ? mångkulturell nationell gemenskap genom interkulturell kommunikation

AbstractIn the literature on multiculturalism and group rights there is a strong tradition that sees diversity as something directly paradoxal to unity. In this tradition, scholars put forward a view of multiculturalism as a divisive and exclusionary process which breaks down the cohesion and unity of society. Related to this notion is that of a neutral and universally valid frame of reference in which political dilemmas can be solved; for example a neutral civil sphere where the ?true essence? of society lies. In this essay I attempt to criticise these two notions.

Att bygga broar - Om delaktighet och inflytande i det mångkulturella samhället

This thesis deals with the issues of participation and influence in the multicultural society. The aim with the study is twofold, first to identify determinants improving participation and influence in this context, and second to see if the ecouragement of a strong civil society in ethnic segregated areas is a possible way forward to a multicultural democracy. This is conducted through a case study of brobyggarna in Malmo, Sweden, and how they as an integration policy is working with these questions. Six qualitative interviews have been conducted with seven persons workning as brobyggare or in close connection with them. Toghether with readings of earlier research this material is analysed through an eclectic model with theories put together in five analythic dimensions, Multicultural democracy, Social milieu, Unequal possibillities to participate and influence and Local powerstructures.

Hållbar utveckling i svensk planeringspraktik : en diskussion kring förtätning och andra ambitioner

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

Utvärdering av hållbarhetsarbete : Utvärdering av beslut inom Chalmersfastigheter

Evaluation of sustainable work within real-estate companies is a relativelynew way of working and the number of companies starting towork with this routine increases every day. Chalmersfastigheter is areal-estate company providing faculties for universities. The company ismainly focusing on decision-making and outsourcing.The aim of this essay is to evaluate decision-making processes andensuring that the right decision is made, with other words, evaluatingthe decision and not the result from the decision. By identifying whatsustainability means for Chalmersfastigheter and in which processesdecisions are made, an evaluation is easily made to see if every decisionis based on the three aspects of sustainability; ecology, economy andsocial. The result from this evaluation will highlight how Chalmersfastigheter prioritize in decisions concerning sustainabledevelopment.This study is based on the ISO 14001 standard and the definition ofsustainable development presented in the Brundtland report.Akademiska Hus is used as an example to present how another companyin the same business has operationalized sustainability.

Rörelsestyrd utomhusbelysning för ett tryggt och hållbart samhälle

I samband med min utbildning till fysisk planerare stötte jag på begreppet trygghet flera gånger. Dock nämndes detta sällan i samband med belysning, utan endast andra aspekter togs upp. Därför tycker jag att det behövs närmare undersökning av hur vi egentligen upplever att en trygg miljö ska vara. Det behövs närmare undersökning av hur denna upplevda trygga miljö påverkas av en annan sorts belysning. Detta leder således till att denna uppsats behandlar ämnet trygghet i relation till belysning, med en inriktning på rörelsestyrd belysning.

Stadens offentliga rum ur ett socialt hållbarhetsperspektiv - Jubileumsparken, ett offentligt rum för unga?

The public spaces of the city from a social sustainability perspective, Jubileumsparken, a public space for the young, aims to see how public spaces can be open and accessible to all young people in the community. New public spaces can be created and formed by urban planning. A public space that is undergoing considerable development is Jubileumsparken, which is situated in Gothenburg. This area constitutes the case study for this thesis. Due to the commercialization in the neo-liberal society of today, there is a risk that economically weak people, such as the young, the unemployed or students, can?t take part of all public spaces.

Svävare : Utforming av hytt

The project in question is a joint effort between students at Karlstad University and Marcus Norström at the company Hovercraft solutions. The project is divided into two parts, one focusing on the purely technical aspects of engineering the product and one focusing on the design aspects of the product development. The project described in this report is the design of the product. The assignment from Hovercraft solutions is regarding design engineering of a cabin for the hovercraft 380TD from the manufacturer Griffon hovercraft. The product lacks a cabin and none is offered from Griffon at the time being. 380TD is a relatively small hovercraft with a length of 6.8 metres and a width of 3.8 metres.The surface available for the cabin is not much different from the body of a car.Because of this, research has been focused primarily on car bodies.The product development process used in the project is following a systematic approach.From a chosen concept, the project was finalized with a CAD-modell as well as a detailed prototype.The weight target of 80 kg was reached and the ergonomic aspects were considered developing the sight field, roof- and entrance height.    .

Hållbarhetsredovisning : Med fokus på negativ information

To establish sustainability reports is an increasing trend for more and more companies. This has led to a spread of the international framework Global reporting initiative, GRI, guidelines to make a sustainability reports. This trend has got a lot of critics from various stakeholders who believe that companies in these reports communicate the information in a way of window dressing. Both negative and positive information has to be represented according to GRI: s principle of balance.  Window dressing is created by adding a greater emphasis on the positive information. The researchers review the context of the negative information to study the extent to which it is reported and whether there are patterns and variations in the reported information.
