3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

The purpose of this master?s thesis is to examine what needs and expectations the patrons have on the local public library services for adult students. With increased knowledge of these matters the library will be able to support and improve the service for users. The focus is on adult students with immigrant background who study Swedish as second language in a municipal adult education school. The main questions are: How do adult students use the library at present? What do they consider to be most important when using the public library for their studies? How do these expectations correspond to their experience of the library services? Two focusgroups and one in-depth interview were carried out.

Background: A patient undergoing surgery will meet many caregivers in different settings pre-, intra- and postoperative in the surgical pathway. Lack of communication is a common digression and the handoff is such an occasion. The purpose is to describe current knowledge about the patients´ right to safe care perioperative. The study is a systematic review (pilot). Result: The handoff was informal, unstructured and inconsistent.

The aim of this thesis is to examine expressions of power and racism in news reporting about the district of Rinkeby, Sweden, in two major Swedish newspapers. News articles are examined using Norman Fairclough?s three-dimensional model for critical discourse analysis. The discourse theory has also been complemented with theories of media in relation to power, ideology and racism. The study has shown that news reporting about Rinkeby largely focused on stereotypical subjects such as violence, social problems and crime.

This Masters thesis concerns epistemology in Knowledge Organization KO, as a field of study in Library and Information Science LIS. Using a theoretical model by Birger Hjørland and foucauldian discourse analysis as springboards, this study analyses three epistemological discourses in the practice of KO. The aim of the study is to show how these discourses are constituted and demarcated in relation to KO, as well as to examine how they fit into Hjørlands model. A brief historical outline of some epistemological trends in LIS is sketched, as well as examples of how different epistemological schools influence different parts of KO, e.g. information retrieval, indexing- and classification theory.

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

In the care for the critically ill patient the next of kin is of great importance. Their support, love and care for the patient, increases the wellbeing and makes a connection to the patient?s normal lifeworld. For the next of kin to be able to be that support the next of kin needs to be helped to maintain the basic need of for example their sleep, food, hygiene and psychosocial support. The critical care nurse must see to the patient?s whole lifeworld which includes their next of kin.The aim of the study was to identify the resources available for the next of kin in intensive care units in Sweden.

This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..

Aim with this literature review is to acqurie knowledge in medical, psychical, psychological and social problems evolving urine incontinence and it´s treatment metods, current legislations and the nurse´s approach towards the patient and transcultural care if the patient comes from another cultural.The results show that this problem affects the women´s life situation enormously above all it brings them a increased social isolation, helpless, sheme, psychological and sexual problems.the nurse should recognise demands and resource with the.by support of diagnostic care, patients can achive good health when there is enough resource patient to be able to support her in her efforts to achive balance i her daily life..

In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.
