Syftet med detta arbete är att jämföra International Baccalaureate Diploma Programme (IB), med svenska SP och NV program. Detta görs genom att besvara frågan hur innehållen i matematikkurserna på IB programmet skiljer sig från matematikkurser som ges i de svenska programmen. Inte enbart innehållet i kurserna jämförs utan även timplanen granskas för att undersöka om arbetsbördan i programmen skiljer sig åt. Den lättaste matematikkursen som undervisas i IB programmet, Mathematical Studies är mest lik de svenska Matematik A-C kurserna. Den andra IB kursen, Mathematical Methods täcker framförallt Matematik A-E kurserna medan den tredje kursen, Mathematics Higher Level stämmer bäst överens med Matematik kurserna A-F och Matematik-diskret.

Along with rising energy prices and increasing awareness of environmental issues, the criteria for buildings energy performance have been sharpened through the years. Today, ?passive house? and ?low energy house? are commonly used phrases in the construction industry and is expected to become increasingly common in the future.For houses with well-insulated building envelope the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the building, compared to the rest of the building envelope.This report deals with detail solutions around windows and a comparison between a traditional slab and a foundation from Koljern consisting of foam glass.

Det här arbetet utfördes på ABB Corporate Research, och innefattar en studie av motorstyrning i allmänhet, och hur man med hjälp av en Intelligent Power Module kan effektivisera motorstyrning genom att ersätta separata kraft- och styrmoduler med en kombinerad modul. En IPM från International Rectifier har modifierats och testats genom att under en längre tid låta den styra en permanentmagnetmotor under normala förhållanden. Resultatet från testkörningen visar att en IPM är ett bra alternativ i framtiden, såväl i fråga om effektivitet, som kostnad och utrymme. Efter en undersökning av marknaden visar det sig att det är långt ifrån säkert att modulen från International Rectifier är den bästa som finns att tillgå, och det skulle förmodligen löna sig att testköra IPM:er av andra tillverkare i mån av tid och pengar..

Over the past twenty years, the cooperation within the European Union (EU) has strengthened and expanded with both more number of Member States and stronger influence on international politics. The unique character of the Union and its ability to enforce peace and humanitarian intervention has attracted attention in political science. This prominent position of the Union is perceived by many scholars who often hold this derived from the Union's influence in international relations. Various terms have been used to define the powers of the Union. The British researcher Ian Manners states that the unique identity of the Union in the international arena is formed by its normative power.  An important policy area within the Union is the environmental cooperation.

International conventions signifies international trade, which in itself would be ineffective if there were no dispute settlement mechanisms. This essay intends to examine how dispute settlement mechanisms between states have developed over the years and a large emphasis is placed on the World Trade Organizations (WTO) Dispute Settlement Body since it?s had great significance for the efficiency of international law. In order to show the need for dispute settlement mechanisms, a background to the conventions that have called for the development of the DSB is in order. This essay focuses on Intellectual Property Rights (IPR), and the agreement that currently regulate intellectual property rights, Trade Related Aspects of Intellectual Property Rights (TRIPS), but also its connection to the DSB.

Child health care in Sweden is today automatically informed of newborns in the district and itis therefore natural for the maternal and child health nurses to contact and invite the new family to the child welfare clinic. So far the social services in the studied county have not reported new adoptive families to the child welfare clinics; instead the families have to contact the clinic themselves. The aim of this study was to investigate how social services inform the child welfare clinics of new adoptive families. The aim was also to investigate how and when the maternal and child health nurse thinks that contact should be established and what information/knowledge she feels a need of in contact with new adoptive families. The study has a qualitative design and interviews have been conducted with social workers, a representative of an adoption agency and maternal and child health nurses working in child welfare clinics.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

In today's society there is a significant focus on energy efficiency. Despite this, people leave lamps, televisions and computer screens etc. powered on unnecessarily. The goal of this project is to build a simple prototype for home automation where a user, via an application on a mobile phone, can switch on and off the power of an electrical products in the home and as well as being able to check whether such products are switched on or off. The prototype will also collect data on power consumption for these electrical products.

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

This thesis investigates how web agencys in Stockholm use, value and incoroprate the terms usability, user experience and interaction design in their work process. The purpose of this study is to investigate how creative professionals works with the notions of usability, user experience and interaction design with focus on the end user. Our definition of creative professionals is every employee at a web agency involved in the work process of developing digital artefacts in any capacity. We wanted to investigate how these notions are considered, consciously or unconsciously, during the workprocess. Semi-structured interviews were conducted at three different web agencys with eight different employees.

Cost allocation ? a study of how Swedish energy companies allocate costs between electricity and district heating in a combined heat and power plant District heating is today the most utilized alternative for heating in Sweden. In a combined heat and power plant (CHP) electricity and heat are cogenerated. The environmental and economic advantages with this kind of production are high. A problem in a CHP-plant is to allocate costs between electricity and heat since both products are generated in the same process.

This essay examines the European Union?s (EU) ability to play a leading role as a global actor on the world stage in international relations. Specifically, this essay studies the EU?s role of negotiator in the UN Climate Change Conference in Copenhagen in December 2009.  This essay also analyzes explanations for this role. Research is based on case studies, with conclusions drawn using an inductive approach.

This thesis investigates how recipient countries' domestic type of democracy affects its inclusive ownership in international development cooperation. This is done by examining Swedish development cooperation with Rwanda and Tanzania during the period from 2010 to 2014, a time when ownership - a concept which emphasizes recipient countries' leadership over its own development - was a central part of the international development agenda. The two cases were selected through a most similar case design where the value of potential explanatory variables was similar, except for the recipient countries' types of democracy. Furthermore, the case study uses a comparative analysis to analyze strategies and reports done by SIDA and the Swedish Ministry of Foreign Affairs. Previous research focuses on the exclusion that national ownership can result in, in undemocratic national contexts. The main argument for this should be seen as the fact that ownership can not be representative if the power of the recipient's development agenda is limited to a decision-making elite.

The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.
