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.

Background for the research problems: Small companies are very important for the economic stability and development, something which the economic crises in recent years have underlined. Therefore it?s important to minimize administrative costs for smaller companies and also in other ways facilitate their further development. For these reasons accounting has been simplified and auditing abolished for smaller companies in many countries. In Sweden auditing for small companies was abolished nearly three years ago.

Within the Swedish school and the public library communities it is generally held as a truth that reading of fiction develops the empathic ability of the reader. This opinion is also expressed in political guiding documents for the school system and cultural sector. This paper's main hypothesis is that there is no assembled theoretic ground for the statement that reading of fiction develops the empathic ability. The investigation consists of two parts, the first being theoretical and the second empirical. Definitions of what empathy and reading is, are reviewed in the first part.

During the early 1990´s, the Swedish commercial air traffic was de-regulated and the new market-condition made it possible for low-budget airlines to enter the Swedish market. The former monopolistic airline company, Scandinavian Airline Systems (SAS), was facing a new type of competition which had the advantage of offering much cheaper air trips than SAS. Adding the decrease of profitability that struck SAS as well as other airline companies after the terrorist attacks on the 11th of September, forced them to carry out a mayor reorganization programme. The programme, called ?Turn Around 2005?, was a direct economical measure that begun in 2002 and lasted until 2005 and resulted in a cost saving of 14,5 billion SEK as well as a notice or a transfer of 6000 employees.The purpose of this essay is to investigate if the opinion of the consumer, the image, corresponds with the profile that SAS wishes to mediate today.

Syfte: I november år 2010 avskaffas revisionsplikten i Sverige för mindre företag. Med den utgångspunkten grundar sig studien i att studera och identifiera de nya förutsättningarna på revisionsmarknaden efter att revisionsplikten avskaffats.Metod: Uppsatsen är inriktad i ett kvalitativt perspektiv. Empirin som samlats in via personliga intervjuer utgår från teori om revisionspliktens avskaffande, från Europanivå till den svenska lagen, för att sedan mynna ut i en analys och en slutsats.Resultat & slutsats: Undersökningen påvisar att såväl större som mindre revisionsbyråer har haft kundförluster, men bara i enstaka fall och har inte påverkat byråerna i någon större utsträckning. Studien är för tidigt ute för att se någon radikal förändring. .

De första allmänna parkerna skapades på privata initiativ. Länge handlade parkförvaltning främst om ren förvaltning av utemiljöerna. Under 80-talet skedde ett skifte i synen på parkförvaltningarnas arbetsuppgifter. Medvetenhet om stadskärnans identitetsskapande roll medförde att man började ta sig an trafikplanering, utsmyckning och gestaltning. Man inför gågator och anordnar aktiviteter i stadens centrum. Många offentliga problem skulle kunna lösas genom att engagera allmänheten i beslutsfattandet, detta gäller i högsta grad även grönytor. Aktivt medborgardeltagande är en framgångsfaktor i många projekt.

This thesis concerns an energy audit of a food industry. The company's business consists of boiling and peeling shrimps, and producing mayonnaise-based salads. This type of work involves energy-intensive processes, such as steam generation, compression of air and refrigeration of large spaces. These needs are supplied with electricity. Furthermore, the industry is a major consumer of district heating, particularly for heating the supply air in the ventilation system.

The main purpose with this study is to make the modified parenting visible in relation to the school over time. How have the views of parenting and support, by the pedagogues and the parents, earlier been interpreted and how is it today? The results of the interviews, which were more like an everyday dialogue, were analyzed through a phenomenological effort with a hermeneutist method interpretation. The theory connection has mainly consisted of relevant terms for this study.I have come to the conclusion that parents today feel that they have an extended responsibility when it comes their own children?s knowledge.

In this study we pose the question if you through finding patterns in implementation of checkpoints can find ways to tailor the experience of the game A Story About My Uncle to hardcore gamers. To find out the answer we had hardcore players playing a modified level from the game A Story About My Uncle that was used as stimulus material for the following focus group interview. The analysis of the gathered material resulted in four patterns that can be used when implementing checkpoints to tailor the experience of the game A Story About My Uncle to hardcore gamers. Elements of checkpoints that our study showed to be important when it comes to how the game is experienced are density, placement and clearness..

Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything.

Bakgrund: De stora redovisningsskandalerna inom bolag som Enron, Worldcom och Palarmat var startskottet för den epidemi som sedan kom att spela en stor roll vid förbättrandet av bolagsstyrningen bland aktiebolag världen över. Kraven på bolagen ökade att informationen som släpptes var tillförlitlig och fullständig. För att säkerställa detta togs svensk kod för bolagsstyrning fram som ett komplement till lagstiftningen berörande aktiebolag. Koden kräver ingen obligatorisk tillämpning i att implementera funktionerna utan har som krav att bolagen ska göra ett aktivt ställningsantagande vid inrättande av funktionerna i koden. En uppmärksammad punkt i koden är 7.4 där bolagen måste beskriva i sina årsredovisningar huruvida de anser sig behöva en granskningsfunktion även kallad internrevision eller inte.Syfte: Syftet med rapporten är att skapa en förståelse för vilka motiv de svenska bolagen med en omsättning över 3 miljarder kronor har haft när de valde att inte följa internrevisionsfunktionen.

This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..

The purpose of this study is to investigate what kind of idea a group of students in third grade, who attends a school in the Stockholm area, have on group work in school and how they think it affects their learning.The study is based on two questions:What opinion do the students have about group work?What opinion do the students have about how group work affects their learning?The method I have used to retrieve information has been to interview six different students, where the interviews were both individually and in groups. I started by interviewing students individually and then had a group interview. The idea with the group interview was to end it all with a brief discussion about the thoughts that came up during the individual interviews. I chose a selection of six students, four girls and two boys which they all were at the age of 9 and go to the same school.The socio-cultural and structural perspectives, is those theoretical perspectives that my study is based on.
