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.

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

The aim of this masters thesis is to analyze how subjects of ethnographical objects should be described. To obtain this we focus on which subject aspects of ethnographical objects that could be possible and valuable to analyze and to index. This is done with the help of established LIS subject indexing theories, and through the perspective of ethnographical museum documentation. The theories are both general, concerning the stages of subject indexing, and more specific, regarding the indexing of pictures. One of the latter is the theoretical model of Sara Shatford, from the article Analyzing the Subject of a Picture.

In this thesis we have developed a framework of features associated with eCommerce platforms and then defined them. Thanks to our interviews with eCommerce-developers, we have been able to define multiple eCommerce features with the focus on an owner?s perspective. Much of the previous research in the area, takes a user perspective when the functionality of eCommerce-platforms have been assessed and evaluated. We have therefore taken an owner?s perspective in the evaluation of eCommerce platforms and therefore produced a suggested framework with key features associated with the owner's functions.

In this essay, we attempt to study and analyze the work towards equality between men and women at the university of Örebro, Sweden. By using discourse analysis we have the ambition to test organizational theory with a gender perspective as the explanatory model for the schools successful work. We also have the ambition to develop our theory and ad an organizational theme focusing on actors..

The aim of this study is to become aware of how the children at the after-school care perceive the adults at after-school care. The most interesting parts are to find out what they thought made a good teacher, which qualities were preferable and how the children expressed their opinions. The children often spend long time at the after-school care which means that the children?s work environment matters. The children look at adults from another perspective and see other qualities than adults see in each other.

The intention of this study was to create an understanding of how multi-professional interaction could convert into inter-professional collaboration, which takes advantage of and acknowledges the individual professional identity. The intention was to understand the meaning of collaboration through the study of meetings between professionals who use different symbol systems. In particular, we wanted to study inter-professional interaction from a symbolic interactional perspective with a focus on Self, Identity, Symbols, Meaning and Professional community. The employed method was semi-structured interviews with ten questions. A convenience sample was used to identify working groups composed of different professions, such as teachers, social workers and therapy assistants.

A reforming trend is captured showing that countries are shifting from defined benefit pension systems towards defined contribution systems. The reforms have been justified through predictions that the defined benefit systems will not manage to provide good enough pensions to members in the future. The newer defined contribution pension plans often include individual financial accounts where individuals have the possibility to choose how a part of their pension savings should be invested. Sweden was early to introduce such a system, which at the moment provides more than 800 funds to choose from. The aim of this thesis is to capture the market risk associated with these individual investments and does so by using Monte Carlo simulations for six selected pension funds.

The National Arts Council[1] has made an evaluation on obstacles and success factors for the interaction between culture and school. In the evaluation report they concluded that teachers and cultural workers have different views on culture and knowledge which creates confusion in their interaction. Thus I became interested to investigate teachers and cultural workers views on culture, aesthetics, and the knowledge that they think the students / children / young people should get from culture and aesthetics. This work is based on qualitative interviews with four teachers and four cultural workers. I compare their views with each other and link it to different research perspectives on culture and aesthetics in school to get an understanding of the similarities and differences in their approach, and what implications it can have in the school?s learning processes. In this work, from a didactic point of view, I found that when the teachers and cultural workers are talking about culture, the why-perspective differs.

This study was about how pupils described their school situation with special education. The specific focus was on pupils which are described as ?troubled pupils?, unconcentrated pupils?, pupils in social and emotional difficulties or characterised by similar concepts. The study was based on a sociocultural perspective and an interactional perspective. The empirical material consisted of interviews with eight pupils in age between 9 to 12 years old and who had special education.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

This report is a documentation of the workflow and the result of a project carried out by twostudents from the Royal Institute of Technology in collaboration with a company. The report isstructured in a chronological order and describes the methods and systems developed in theworkflow. The report shows how the project evolved from a study phase to the various proposals onthe concept solutions.The project aims to develop a systematic way of bonding two different kind of cardboard under fiveminutes. By conducting a general study about glue and its different forms it was possible to obtain abroad knowledge, which helped to choose the right substances to later use in testing on the differentcardboard materials in question. Glues's survey resulted in a list of different substances that wererelevant to the project.

This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.

The purpose is also to show the difficulties with subject access, i. e. to find a similar book to the one you just read; problems with traditional systems versus the usefulness with recommender systems like Amazon.coms Similar Items. Similar Items presents a set, a cluster of related items to a given item based on customers co-purchase.

AimThe aim of this study has been to examine how health enhancement teachers in Montana, USA, view the value of physical activity from a lifelong perspective.In what way does the health enhancement teacher think the importance of physical activity from a lifelong perspective could be presented?What resources are available for teachers to present the value of physical activity from a lifelong perspective?MethodThe issue has been answered through qualitative interviews consisting of six health enhancement teachers, four women and two men, in Montana, USA. One of the teachers worked at an elementary school (for 30 years), three teachers worked at middle schools (20, 10 and 8 years of work experience) and two of the teachers interviewed worked at a high school (30 and 3 years).  ResultsThe majority of teachers feel that a wide variety of activities, adapted to an individual level, and the understanding of a healthy lifestyle are important in order for the teacher to present the value of physical activity from a lifelong perspective.The teachers felt they had sufficient material in order to present the value of physical activity, where the school budget provided the teachers with materials every year. In addition to the budget, all the teachers had 12 hours of professional development every year where they could attend conferences or their own choice of professional development.ConclusionWith the help in forms of professional development offered by the school, conferences, meeting with other teachers, and their own choice of development, the teachers instruction techniques could increase which could help the teachers to find the pupils? interest for different kinds of physical activities.KeywordsPhysical education and health, physical activity, SOC, sense of coherence..
