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.

Master thesis in Business Administration, Swedish Business School at ÖrebroUniversity, spring semester 2012Authors: Anders Oskarsson & Christian UhlanderTitle: I?m going to make you rich! -With a little help from PiotroskiResearch objective: This paper examines whether a simple account-based analysis strategy,F_SCORE, can improve returns earned by an investor. The results show that F_SCORE generated a69,7 % annual return between 2001-2010 at the Swedish market, which was better than the furtherdeveloped model A_SCORE. Overall, the evidence suggests that the market does not incorporatehistorical information into prices in a timely manner.Methodology: The foundation for this thesis is based on a quantitative approach and empiricalmaterial is gathered from Thomson Reuters Datastream for the Swedish market..

The aim of this study is to contribute knowledge about how preschool teachers reason around their role in the work with children being maltreated. The study has been based on the following questions: How do the preschool teachers identify children being maltreated ? How do the preschool teachers act after they have identified a child thats being maltreated? What difficulties experienced preschool teachers based on their professional roles related to child maltreatment? The method used in the study is a focus group interview, which is a kind of informal group discussion. The result shows that there are difficulties in the preschool regarding the work with children being maltreated. Some of the difficulties that the preschool teachers raised was the contact with the guardians, society?s negative perception of the social services, that all the notifications must go through the pre-school manager and that they don?t have so much experience of notifications. .

The premise for this study is the question how we should relate to people with different religious beliefs. The aim is to examine if an existence characterized by a religious diversity should affect the certainty and confidence in our faith. To answer my question I have turned to the philosophers David Basinger, Mikael Stenmark, William Lane Craig and Robert McKims different views on this issue. Using an approach based on a comparative method and argument analysis I have then assessed their different opinions in the matter. Based on my own discussion of these arguments I conclude that a religious diversity should imply a reduction in our own religious confidence and that it should be reduced in relation to the amount of disagreement that exist between conflicting religious perspectives in an specific case and matter.

Abstract Over the years the consciousness of risk has grown. It?s hard to influence risks, therefore there are guidelines stating that significant risk must be included in the annual report. This paper is a case study; the purpose was to examine how four Swedish listed companies chose to disclose their internal and external risks. Risk is initially described in general sense and then it figures to what constitutes an economic risk.Through a case study of four Swedish listed companies? annual reports we have, through qualitative methods found how the companies chose to disclosure their risks.

We have made a suggestion for a map based search tool used with a database containinginformation on natural disasters. The database is being developed by NCO (SwedishCentre for Lessons Learned from Incidents & Accidents).We examined both Swedish and international examples of databases on naturaldisasters. The examples that we found were often hard to get the hang of, due to poorcompilation. The problem, that is typical of the international examples, is that the processof data collection is not standardized, as it is performed by different organizations andcompanies with diverse demands on and needs for the database. Therefore, to keep itsymmetrical, there ought to be only one department with the overall responsibility for anational database on natural disasters in Sweden.The natural disaster we based our study on was the flooding in Arvika in the year 2000.We inspected the availability of data about the flooding, and found it to be satisfying.Through contact with the municipality of Arvika, by mail and telephone, and a visit at theArvika municipality office, we acquired reports on the flooding and the joint rescueoperation that followed, and also GIS layers showing the extension of the flooding..

With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.

Background: Critical conditions to become an attractive supplier of knowledge based IT-services in the B2B market are many. Besides the fact of supplying a service of high quality one must as a supplier communicate values which are understandable and desirable for a new buyer. Buying a knowledge based IT-service involves several risks; the consultant might not have sufficient knowledge or have difficulties understanding the corporate culture and collaborating with other staff within the client?s organization. Since services are intangible offers and it can be intricate to put right price level for something which can only be evaluated when the project is finished, puts severe strain on suppliers competing with other companies in the same market when looking for new clients.

The aim of this project was to create an interior design for a children?s hospital patient room with the concept to adapt the room for the wide target group from 0-18 years of age. The analysis in the project is based on the hospital ward 322 at Drottning Silvias Children?s and Youth Hospital in Gothenburg. It?s an oncology ward where the children are very sensitive for infections and therefore need to be isolated in their rooms for 3-4 weeks.The main goal for the project was to create a room that works as a template and gives the people who lives in it the opportunity to create thier own room based on the personal things they bring into it, and how they decide to furnish and use the room.The result of the project is a template room with fixed furniture that can be transformed due to screens in the room.

Income support is granted to those who are not by themselves or in any other way able toachieve a decent standard of living. Assessment of entitlement to income support is based onan individual evaluation and equal treatment (Kjellbom, 2009). Administrators of economicaid should therefore not judge clients differently depending on, for example, gender. The aimof this study was to commence from a gender perspective in understanding howadministrators of economic aid think of equality and inequality between the sexes whenheterosexual couples apply for income support. Based on this objective we arrived at twomain formulations of questions; how administrators of economic aid deliberate aroundequality and inequality between sexes in connection to applications for financial support, aswell as which variables in organisations sustain or discourage inequalities between genders inaid management.

The aim of this study is to examine how zodiac signs are depicted through social interactions from an identity perspective and if zodiac signs can be seen as a form of divination. Our method was based on the answers of seven informants (six interviews in total), all of whom were interested in astrology with two of the informants having the title of astrologer by profession. After the implementation of Erving Goffman?s dramaturgical theory regarding identity and Jesper Fr?kj?r S?rensen?s divinatory perspective, we found evidence in the orrelation between zodiac signs and identity, along with astrology having little to no correlation with divination. The results show that although the majority of the informants were hesitant to the assertion that astrology can provide divinatory evidence, many of them still consumed and followed astrological advice based on prognosis.

The main purpose of a logotype is to harmonize with a company?s business concept and culture. This study is based on the receiver?s attitudes about three different logotypes - Volvo, Telia and Mcdonald's. It informs the reader about the importance of a logotype as a mean of communication and if the perceptions of the logotype harmonize with the profile of the company.

The aim of this study is to examine the religious landscape of Brazil, and based on the theory of secularization by Pippa Norris and Ronald Inglehart to explain why Brazilians are religious and not secular. The study is a secondary analysis that uses existing statistics to examine different units of analysis of Brazil?s religious landscape, economics and equality, etc. Based on their theory I find that Brazil is still religious due to the lack of security in the country. Brazil is insecure in terms of measures of socioeconomic equality, stable politics without corruption, and physical safety of the citizens in Brazil.

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
