Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult. Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed daily. The project is performed at Vattenfall´s district heating power plant in Uppsala. Information is gathered through discussions, drawings of the plant and guided tours of the plant.

Internet and digital technology has changed the way we live our lives. As individuals we've found new ways to communicate, educate and experience. But what's the effect on B2B marketing? Previous research presents transactional benefits such as lower costs and easier access to information, but there is limited research done on more complex and long term relationships as well as on modern digital tools. The purpose of this thesis is to investigate whether a deeper long term B2B relationship can be created and nurtured using digital tools for communication, and if so, how these tools and processes can be described and understood.

The aim of this study was to investigate leadership in public health care. The methods used were shadowing and semi-structured interviews. The shadowing involved observing the shared leadership of two head nurses in an administrative management position of a ward in their daily work during two weeks. The observation was supplemented by ten semi-structured interviews. A thematic analysis of the data was carried out and the result indicated that shared leadership is a form of leadership well suited for an organisation as big and complex as the clinic where the study took place.

2013 är det första året samtliga fyra svenska storbanker frivilligt väljer att upprätta separata hållbarhetsredovisningar. Syftet med denna uppsats är att undersöka för vilka intressenter de svenska storbankernas hållbarhetsredovisningar som avser 2012, är mest relevanta. Studiens empiri består av en kvalitativ tvärsnittsstudie som utvärderar respektive hållbarhetsredovisning och sammanfattningsvis ger en helhetsbild av fenomenet. Empirin analyseras med stöd från teorier och forskningsstudier med koppling till hållbarhetsredovisning. Studiens analys resulterar i en slutsats som visar att storbankernas hållbarhetsredovisningar är mest relevanta för storbankernas egennytta i form av ett strategiverktyg som samtidigt belyser företagsandan..

This study is an attempt to shed light on problems and possibilities of the school library of the Swedish comprehensive school concerning library law and goals of the school and the school library. Many investigations about the role of the school library of the comprehensive school have been carried through. They have all more or less come to the same conclusions. In spite of Swedish library law and goal documents of the school library, the school libraries are often neglected, if not will and commitment are to be found among teachers. Using a model of the school organisation by Gunnar Berg, three cases of school libraries are presented and analysed in a larger organisational and political perspective.

I komplex analys finns det ett antal olika konvergenser varav vi tittar närmare på några här. Bland annat hur likformig konvergens medför punktvis konvergens men att det omvända ej gäller. Vi tittar också på vad de har för samband med lokal likformig konvergens och normal konvergens dvs. likformig konvergens på kompakta delmängder. Slutligen kommer vi att se på vad som gäller för familjer och kommer då in på lokalt begränsad, ekvikontinuitet, Arzela/Ascoli, Montels och Runges satser.

Working life changes, just like the rest of today?s society, at an accelerated pace. It is through changes and challenges that human beings develop, personally and professionally. Changes are often met by resistance. The purpose of this study is to see how different factors influence individuals? experiences of change.

Globalization is one of the most popular catchphrases in the international relations debate today. Globalization is a complex concept with as many definitions as authors. National borders or jurisdictions do not control the phenomenon, instead, it is moving without restraints from region to region. Is this a threat to the sovereignty of nation-state and an end of the system of Westphalia? Does the globalization undermine the nation-state by increased factor-mobility, less tax revenue and participations multilateral co-operations, as the globalists think? Or is it strengthens its importance by offering better allocation of resources through free and healthy competition, as the skeptics believe.The aim of this thesis is to analyze theories of globalization by applying them on Sweden and the Netherlands.

Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.

The project was carried out together with OC Off Course who manufactureand distribute mainly electric bikes.In today?s society, alternative sources of transportation becomes more andmore present and several bicycle sharing programs arises in major citiesacross the world every year.Something that doesn?t exist too much as of yet is bike sharing programsthat uses electric bikes. An electric bike is a convenient way oftransportation as well as a good way of avoiding traffic. With an electricbike you avoid having to sweat when biking over hills or when you need totravel over longer distances.The goal of this project is to develop a bike sharing station according tothe functions need to be met.This thesis Is based on Fredy Olsson´s methods principkonstruktion aswell as a couple of concept generating methods from Kenneth Österlin.From this, a number of sketches were made that later was evaluated inseveral steps in conjunction to a set of specifications. A 3D model of theselected concept was later made in CatiaV5 for a complete product..

Sweden?s energy consumption is divided into three major sectors. One of them is the industry sector. One third of Sweden?s energy consumption is converted in the industries.

The essay describes the bachelor project by Marie Hanås, in collaboration with Skälsö Arkitekter. Skälsö Arkitekter are currently developing an area in the north of Gotland, Bungenäs; previously home to lime stone quarries and military bases.The brief was to design a set of outdoor furniture to complement the new development. The main effort of the project was in designing furniture that would fit the environment visually but construction issues were a major secondary concern, to ensure the easiest possible manufacturing. A reference group of coastal house owners were interviewed, and their feedback, together with an analysis of functions, trends and target groups, were the base for the ideas.Of the five concepts presented, Skälsö Arkitekter chose one to develop further. This was done through sketches, models and 3D models and led to the final result which is lightweight furniture of Gotlandic pine wood with an industrial touch.

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.

It is of increasing importance to in the most effective possible way, manage and control all the transactions of raw materials, products and information that are exchanged between an organization and all its operators. These flows and the need for strategy and managing the processes of planning, implementing and control of the supply chain, has given name to the concept supply chain management. Supply chain management involves all movement and storage of raw material, and all the processes that is needed to manufacture a product from origin to consumption. Globalization, technology and increasing time and quality-based competition are all driving forces behind the concept and reasons for an increasing interest in supply chain management.The purpose of this essay is to by using a qualitative case study examine which decisive success factors that can be identified for effective supply chain management. We have compiled different theories on the subject to use for analyzing a case study Li & Fung, who is a successful supply chain management company.
