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.

This essay is about gender equality in a Swedish upper secondary school. The aim is twofold: to obtain knowledge about feminism, gender equality, boys´ and girls´ situations in schools and gender equality work there; and to find out if government management documents for schools work effectively when it comes to promoting gender equality in schools. There are four research questions: How do teachers interpret what´s said in management documents for schools? What strategies do teachers use to promote gender equality? What opportunities and obstacles do teachers see for promoting gender equality at the specific school? And, finally, do the management documents for the school work effectively when it comes to promoting gender equality?The study has a socialist feminist perspective, which sees gender differences as a result of a mix of biological, historical and social factors. Important theoretical standpoints include gender socialization as an explanation for how girls and boys become women and men.The results of the study points out that teachers interpret management documents differently, and that they find the documents hard to understand.

The population growth and urbanisation in low-income countries bring issues of poor living standards and miserable sanitation conditions onto the agenda. If well-functioning waste Management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities. This master?s thesis project is performed with the intention of developing functional decentralised waste management units in the city of Pune, India.

Anställda i det studerade kunskapsföretaget verkar undervärdera vikten av det ledarskap den formelle ledaren utövar. Detta har vi illustrerat med en egenhändigt konstruerad ?tonåringsmetafor?. Vidare har vi kommit till slutsatsen att informella ledare och en stark företagskultur är faktorer som på ett framgångsrikt sätt kan komplettera ovan nämnda ledarskap..

Problem Vad är grunden till att ett företag outsourcar vissa delar av sin verksamhet? Är skälen rent ekonomiska eller finns det andra faktorer som väger tyngre? Vad vill företagen ha av sina leverantörer? Vilka konsekvenser uppstår och hur hanteras de? Syfte Syftet med uppsatsen är att ur ett ledningsperspektiv belysa orsakerna till outsourcing samt de konsekvenser som förenas med outsourcing. Syftet är vidare att belysa det köpande företagets syn på leverantörsförhållandet och hur köparen utövar kontroll över den outsourcade verksamheten. Metod Uppsatsen bygger på sju intervjuer som är fördelade på de fyra fallföretagen Akzo Nobel, Pilkington, Trelleborg Wheel Systems och Tetra Pak. Våra intervjupersoner ingår i företagens ledning eller har tjänster nära ledningen.

Parallel to new technological advancements, including the development of interactive recommender systems, digital music services on the Internet, such as Spotify, have in a short time span gradually replaced former physical media such as CDs and MP3-players and become pioneers on a market with an otherwise uncertain future. By subscribing to the service, users have access to a vast library of music and from any device with Internet access. In order to provide a satisfactory and useful musical experience, different ways of coping with the vastness is required - which is precisely what recommender systems are for. Improved filtering techniques and use of devices built in sensors, make way for new opportunities of more precise and contextually tailored suggestions for track selection, which in turn leads to potential privacy issues when using interactive music services. But where do we stand today? By compiling, exemplifying and discussing three different perspectives with relating to the development of interactive music recommender systems, the objective for this paper is to provide a for science, industry and user, objectively nuanced account of current potentials and expectations.

Motivation främjar innovation, men innovationsprocesser måste samtidigt ta hänsyn till organisationens förutsättningar. Det krävs en jämvikt mellan flexibilitet och struktur i organisationen där team är ett optimalt sätt att skapa en sådan balans. Resultatet presenteras även i analysverktyget ITM med praktiska tillämpningsområden..

Olika teorier kring varumärkeshantering och varumärkesbyggande ställs mot empiri och sekundärdata från tre fallföretag som bytt eller ska byta namn. Empirin är insamlad via kvalitativa intervjuer under våren 2006. Fokus ligger på huvudfallet, E.ON, och hur deras namnbyte gått till och vad det fått för konsekvenser på företagets varumärkeshantering. Resultatet diskuteras utifrån överförbarhet och förslag till fortsatt forskning. Det innebär i korthet att ett namnbyte påverkar flera aspekter av ett företags varumärkeshantering bl a såtillvida att arbetet med att skapa varumärkeskännedom initialt intensifieras.

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.

While studying at the landscape architect program in Uppsala I found stress to play a major roll in the education. To help myself and others to handle the negative stress within the profession and the education I choose to write my thesis about landscape architects' work cultures. Swedish Association of Architects is in second place in the SACO study on long-term sickness for fatigue syndrome, stress and depression. The issue needed to be addressed. My purpose with the thesis has been to study the work cultures in the landscape profession and training and to study and find ways to manage negative stress in the profession and in education.

In recent decades, public relations and news management have become increasingly important in organizations? communication efforts. This thesis aims to show how the Kalmar municipality works with this type of strategic communication to build the Kalmar brand and how their communication efforts can be improved. The thesis is mainly based on theories concerning Public relations and News Management but also the medias impact on forming opinion. An important issue throughout the thesis is that all theories must be related to the fact that the study concerns an organization in the public sector and the obligations that comes with that fact.

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 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.
