Temperatursprickor i ung betong : Utvärdering av projektering och utförande av åtgärder, samt utveckling av dimensioneringsmetod för kylsystem
The report contains three parts. The first part is a summary and overall presentation of thermalcracks and preventing measures against such cracks. This is a theoretical part where theinterested designer can get acquainted with various alternatives, be guided to more detailedliterature, and receive some practical information regarding the design of the respectivemeasures.The second part deals with calculation of the risk for thermal cracks and design of water coolingas a limiting measure. Two complementary methods are reviewed for efficient calculation:?the handbook method CraX1(by Lulea University of Technology) is used for quickverification?finite differential analysis in the calculationtool ConTeSt Pro for more precise projectingHere is also presented a development of existing standards through design of the cooling systemby means of the Bernoulli equation.
Utformning och installation av musikstudio samt audiosystem för inspelning och redigering
The education program System design at the University of Kalmar has since it?s beginning been missing a near by studio for it?s students studying towards audio and music. In the choice of examination project I would take upon this task, which was long wanted for the teachers and students at the university?s Musikhuset.Musikhuset became the buyer of the project, and the studio was to be installed at their premises. Unfortunately, the project got jammed by the university?s financial savings calculations, and was due to this delayed in the end for 11 weeks.
Ett mät- och reglersystem för temperaturkompensering
An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed.
Ramar och reflektion : Om designprocessen som didaktiskt alternativ
By studying literature concerning design, didactics and reflection, and complementing those explorations with interviews with experienced design educators, this thesis challenges the idea of aesthetic media education being purely aesthetic in its characteristics. Drawing from their own experiences as a media aesthetics educator and an industrial designer, the two authors argue that the work flow used within most fields of design, commonly known as the design process, might provide a suitable didactic alternative to a field of education lacking relevant methodology. The literature study offers a better understanding of the design process and how it may be defined and viewed within an educational context. The interviews provide a more practical insight into the world of design education. The result shows that the design process as a didactical method theoretically offers both elements of critical thinking as well as direction and frames for students lacking aesthetic and artistic experience.
Att formge avatarer med hänsyn till anonymitet
This paper describes the process of producing avatars for Jiddr. Today, social media surrounds the lives of youth, and communication via the Internet is an everyday occurrence for most people. Jiddr is an app that was created to give youths a platform for engaging with adults and other youths. It is a moderated forum which gives young people the opportunity to come i contact with adult role models who are knowledgable within various subject areas. On Jiddr, users are anonymous, and this is something I have placed much importance on during the design process.
Bioorganisk fastfas syntes för att skapa intelligenta ytor
This thesis investigates three different surface modifications, and the route to design and synthesize them. The thesis is therefore divided into three sub- projects. (i.) Design and synthesis of a peptide which secondary structure could be controlled by a negatively charged surface. (ii.) Design and synthesis of a cyclic peptide, that would self-organize prior to surface interaction, using the type I anti-freeze protein of a winter flounder as template. (iii.) The use of solid-phase synthesis to make the synthesis of SAM-molecules easier..
Konstruktion av datainsamlingskort för mätsystemet COMET
During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.
Open design : En studie om öppna ickekommersiella kollaborativa designprocesser
Design har en otrolig förmåga att föra utvecklingen framåt men det finns många som är kritiska till hur design utvecklas i västvärldens samhälle. Syftet med denna uppsats är att analysera open design för att ge ett alternativt perspektiv på industridesign. Open design handlar om en designprocess där vem som helst kan delta, utveckla och tillverka produkter. Metoden har sin grund i open source-rörelsen som hastigt spreds i och med internets utbredning. Open design är dock inte lika välutvecklat då rådande marknads- och företagssystem till viss del hämmar detta.
CODP Co operative design process - from urban strategy to detail
This project investigates the cooperation between architect and engineer. The context of the investigation is the design of buildings for a sustainable society. The goal of the project is to further the development of the sustainable built society by increasing the knowledge of the interdisciplinary cooperation between these two fields. The focus is a close cooperation already from the start of a project. By involving both fields in the early design stages it is thought that the knowledge and skills of each field is better utilized.
Abort n Go. : Med fullständiga rättigheter
ABORT ?n GO is a design project within the crossing boundaries of Critical Design and IndustrialDesign.The contemporary discourse on abortion is problematic, and infected by double norms. Thesenorms may cause feelings of guilt and shame in women who have an abortion. The abortion rightis built upon conflicting standpoints; one is that women have right to have an abortion, withoutbeing questioned. Second is the notion that abortion is something that should be avoided, implyingthat you?ve done something wrong if you have had an abortion.With this project and physical product I want to explore and discuss the contemporary discourseon abortion in Sweden.
Ett socialt nätverk anpassat för äldre : En studie av det sociala nätverket Modernfamilies
In this paper we analyze a social network specifically designed for the elderly, people with Dementia and people with generally low computer experience. This is a relatively unexplored use for such software, and our goal is to find out whether the technique to be used is simple enough to use for the intended user group, and generally how the whole situation is experienced by the users. To achieve this we conducted an expert evaluation and interviewed a number of users at two separate occasions during their first weeks with Modernfamilies. We came to the conclusion that this software generally is simple enough to use for the intended target group. Some of the users we came in contact with experienced the software as a positive addition to their daily lives, while some could not see any reason for a further use.
Systemutveckling och användbarhet -Att utnyttja användbarhetstester i systemutvecklingsprocessen
Den här rapporten behandlar frågeställningen om hur man kan anpassa systemutvecklingav ett informationssystem enligt livscykelmodellen till att inkludera användbarhetstester. Frågeställningen grundar sig i att god användbarhet inte är ett explicit uttryckt mål i Andersens beskrivning av livscykelmodellen. För att besvara frågeställningen har vi utvecklat och testat ett bokningssystem åt en mindre verksamhet. Utvecklingsarbetet har bedrivits enligt en egen anpassning av livscykelmodellen. Testerna har utförts enligt metoden cooperativ evaluation.
Diskurser i referenssamtalet: En diskurspsykologisk studie
This Master's thesis aims to investigate the reference interview using the discourse analytical method discourse psychology. The reference interview has been studied thoroughly, and its importance has been proven repeatedly within the field of Library and Information Science (LIS). However, it has never been studied from a discourse analytical point of view before.The material for our study was gathered at Malmö public library, and consists of 10 tape-recorded and then transcribed reference interviews. Our study shows that there are several discourses within the reference situation. The dominating discourse, the reference interview discourse, is found within all the reference interviews.
Verifikation av verktyget aspect analyzer
Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.
