Virtuella vävnadsobjekt för medicinska träningsapplikationer

This Master thesis discusses the development of a virtual human soft tissue object for use in exercise applications of various medical procedures.The soft tissue object to be developed shall look like, feel like and behave as living human tissue. It shall give the user a realistic feeling of weight, softness and roughness, and shall behave in a correct way for exercise purposes. The soft tissue model is to be used in a three dimensional stereo graphic environment with haptic feedback. A prototype for practicing the procedure of inserting a catheter is built. The prototype is used to evaluate the potential of the virtual environment for medical exercise applications, and to assess the realism and usability of the soft tissue object.

Brandsläckning och textil restvärdesräddning Hur saneras textil efter en pulversläckning?

This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.

Shape from Silhouette Scanner

The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.

????Att lösa reglertekniska problem med Modelica

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.

HUNTER'S BEND - med vad vi bär berättelse

The Hunter?s Bend project is about how our personal possessions affect our perceived identity and in what way the value of an object may increase with the relationship that is built up towards the user. I have looked upon traces of time as an extension of an existing object. The outcome is a series of leather cases made out of one piece of folded leather, hardened and locked within itself. The history contained in leather, as a living material has been an important part of the project as well as how its features are used in the making and then allowing the product to change after use..

Corpus Leakage

We understand the world around us through categorization and classification. But things are morecomplex than that, life is mixed up, flowing and unable to stick to labels. The main purpose ofcorpus is to contain, organize and control food and beverages. Corpus objects are also socialmarkers that have a tradition of being elitist; in both choice of material and in that they imply acertain way of usage. Corpus objects are heavily loaded with tradition and rituals.

Design av stimuligenerator för radarmålsökare

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

Är brottsoffret ett subjekt eller ett objekt? : En diskursanalys av brottsofferbegreppet

The purpose of this essay is to define the meaning of the concept of crime victim and how the crime victim as a concept is constructed. The question is answered through an investigation of the discourse that constructs and reproduces the crime victim. Furthermore the purpose is to open a theoretical discussion which aims to clarify whether or not the crime victim is a subject or an object through an examination of how the individual is constructed as a crime victim by the crime victim discourse.The essay takes a theoretical point of view based on a mixture of Michel Foucault?s and Ernesto Laclau & Chantal Mouffe?s discourse theories. The method used to organize the research ? regarding the meaning of the concept of crime victim ? is Laclau & Mouffe?s discourse analysis which is an extension and a part of the theory mentioned above.The discourse analysis creates a model of the crime victim discourse which answers the question of how the concept of crime victim is constructed, and how this concept should be understood.

Magiska ögonblick och förlorade möjligheter : En studie i möjligheterna att lära med utgångspunkt i elevernas förkunskaper, svårigheter med lärandeobjektet och variationen i det erbjudna lärandet.

This study is based on an interest in trying to understand what is needed to ensure that students actually learn in a learning object, in this study equations. Algebra is an area of mathematics in several studies proved to be a stumbling block for many students. Using letters in mathematis is difficult for most students according to research reports and it is also consistent with my own experince as a teacher. The purpose of this study was to seek answers to what in the lesson content and also during the interview that allowed the students to learn more about the learning object. Based on students' prior knowledge and the difficulties students might have with the learning object and the offer of learning, I try to get an answer to what might have contribut the students to developed knowledge of the learning object.

Inventering av förorenad mark på LKAB's industriområden i Kiruna, Svappavaara och Malmberget

The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted.LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

Objektspecifik möbeltextil

My project aims to understand more about the methods used in making woven textiles on an industrial level, and how these tech¬niques can be adapted to create object-specific pieces. On visiting the furniture fair in Stockholm, I was surprised to see that most of the textiles used for furniture were so similar, despite the variation in the furniture itself. My project is about creating textile patterns that are specific for each piece.The idea behind the process could be used for any product, but the pattern I created is specifically for the armchair Accent by Yngve Ekström. I wanted to create the feeling of a pattern moving over the surface of the object and adjusting to it. I worked primarily with differences in density.

Dimensioner. Mellan 2D och 3D, en undersökning av yta och innehåll

A project exploring the boundaries between 2D and 3D. What is surface and what is substance? A countinuation of previous projects where I?ve examined the journey from two dimensional paper to three dimensonal objects. This project deals with the journey from three dimensonality back into a flat two dimensional surface, and the question if something can be both 2D and 3D at the same time. I decided not to center the project around a specific item, but rather let the project itself be in focus.

Problem vid beslagtagande av egendom

This thesis takes its starting point in the 27 Chapter 1, section 1 of the Swedish code of judicial procedure, where the following is found:?objects reasonably presumed important to a criminal investigation or taken from a person through a criminal act or subject to criminal forfeiture may be seized?In this thesis we have investigated what kinds of problems occur when the seized object is part of an investigation of IT-related criminality. We have used methodological investigations of Swedish laws, legal usage, and the preliminary work with laws. Further have three interviews been made with different actors affected by or involved in seize of objects. These persons were a police officer, a public prosecutor, and a person whose object has been seized.The result we present is that there exist three kinds of problems related to objects that are seized within the demarcation of this study.

För sakens skull : Det omöjliga mötet i Rut Hillarps roman Sindhia - en lacansk läsning

This essay examines the love affair between the two main characters of Rut Hillarp?s novel Sindhia. It draws attention to the schism between the Surrealist version of love as an extatic-religious fusion of the sexes ? that in a way marks the relationship ? and the yet remarkable coolness between the two lovers.With the theories of French psychoanalyst Jacques Lacan, I will show how the man and the woman project their unrealistic individual fantasies on each other, thus rendering impossible the Surrealist Meeting, with its road to an absolute reality. The Surrealist "l?amour fou", I will argue, is trapped in the ritualized "l?amor interruptus"; a lacanian term for a certain kind of love that wishes to conceal the fact that desire will never find its object.
