Kommunikation och samverkan mellan projektering, inköp och produktion (PIP) i ett byggprojekt. En utredning av en PIP-plan och ett förslag på en arbetsplan.

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

Elektromekanisk växel för tunga lyft : Konceptutveckling

The basis of the study lies with a newly patented gearbox by cardiologist and inventor Stig Lundbäck. Stig founded CorPower Ocean AB to further develop the gearbox to be used in a wave energy device. The purpose of this project is to develop a concept of a lifting system with CorPower Oceans gearbox that is more energy efficient than a hydraulic lifting system. The goal is to use technology from CorPower Oceans gearbox inversely to perform heavy lifting as an alternative to hydraulics. The project is limited to applying the gearbox and gear rack on a forklift with a lifting capacity of ten tons.The main tool in this project will be the product development process Systems Engineering where only the most relevant parts will be used to develop a concept.

Ideella organisationer- En arena för diktatur

The purpose of this research was to examine the current field of management in non-profit organizations, mainly focusing on managerial approaches, but also the impact of organizational size on the shaping of governance. Non-profits are widely discussed in contemporary research, particularly due to the increasing external pressure on voluntary organization to professionalize the way they work in line with standards in the private sector. Due to this our thesis aims to investigate whether professional, bureaucratic approaches are useful when governing a non-profit organization, or if social structures are enough to ensure goal congruence and efficiency. To conduct this research qualitative interviews were carried out and a case- study was made, using the Swedish Karate Federation as object of study. Results show that formal and more professional structures are useable to achieve efficiency and prevent inertia within the organization.

Modellering av indunstning på Södra Cell Mönsterås

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Energiberäkningar för passivhus

AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.

Lagring av kyla i bergrum : Undersökning av ett nedlagt oljebergrum

This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.

Solvärme med säsongslager i Lyckebo

The purpose of this thesis is to investigate and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather facts in order to provide a picture of its current condition and potential for continued use. The thesis investigates the plant's history and problems with the rock cavern losses, and how the operation developed. It also presents the calculations regarding the possibilities of again supplementing the facility with solar energy - which is not the case today - as well as the economic conditions for it. Regarding a re-launch of solar energy, primarily a concentrating solar collector has been studied, as it has the advantages of an integrated control system.

Lokal demokratiutveckling - En studie om demokratiutvecklingens orsaker och förutsättningar i Hallands kommuner utifrån ett deltagardemokratiskt perspektiv

The aim of this essay is to study the development of democracy in the Halland province, with focus on participating measures. First and foremost to test earlier research about the causes of the development of democracy, which says that the work takes place with obvious variation between the municipalities and that it is caused by economic resources and experienced problems in the democracy. The purpose is also to conduct a general discussion about the conditions and effects of the development.Thus the method can be characterised as theory consuming because I as far as possible assume the method that has been used in earlier research. Still, my study is limited to the six municipalities of the Halland province and is therefore a study of few cases. One person in each municipality has been interviewed in order to collect a list of all the measures that have been carried out.

Snabbt, säkert eller skönt? : Cyklisters preferenser i trafiken

Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.

Incidenter på svenskt sjöterritorium : En analys av de åtgärder som vidtagits vid incidenter orsakade av Öst- respektive Västblocken under 1960-talet

Sweden has long been nonaligned in peace with the aim to remain neutral in the event of an outbreak of war. Building confidence for this neutrality was important for Sweden during the Cold War. This placed high demands on the Swedish Navy to detect and repel violations of Swedish territorial waters. The archives, which contain the secret reports on the violations that occurred during the 1960s, have recently been opened up.The purpose of this essay is to study how the incidents that took place in Swedish territorial waters in the 1960s were managed and to examine if the handling of them was different depending on whether they were caused by the east or west side. Furthermore, the aim is also to try to categorize and interpret these measures from the two pairs of concepts of deterrence and reassurance and integration and screening.In making it possible to answer the questions, all the reports - 66 altogether - which refers to the incidents which occurred during the years 1962 through 1969, have been studied.

Mellanstatligt samarbete mot människohandel i Europa : ? en studie om mål, åtgärder och resultat

This paper provides a study about human trafficking with sexual motives performed in European states and the measures taken from national, international and Non-Governmental organizations with the purpose to oppose human trafficking. According to the UN human trafficking has increased and shows tendencies to continue escalating, regardless of the measures taken by various organisations. In this study, four countries with associations to human trafficking have been chosen and organisations related to these countries are studied. The purpose is to inquire into how these organisations work against human trafficking and which objectives and guidelines these organisations strive for together with their values. The aim is to find out which result the organizations efforts gets and if, according to my hypothesis, the efforts oppose themselves.

Den svenska kärnkraftspolitiken : En processpårande fallstudie av svensk kärnkraftspolitik

This study deals with Swedish nuclear-energy politics from 1980 to 2006. The purpose is to trace and to explain change and stability in three political parties? rhetoric concerning the phase-out of Swedish nuclear-energy and the Swedish government?s nuclear politics. Two hypotheses based on path dependency theory are tested to analyze if rhetoric and politics are developing in separate directions. The first hypothesis is based on the idea that earlier promises from the political parties affect what promises they can make later on.

KappAhls sociala ansvar. Hur ser det ut i verkligheten?

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.

Optisk sortering av matavfall : en jämförelse med en minskning av svinnet

The purpose of this study is to compare the energy related and environmental consequences of implementing optical sorting as a means of waste collection with those of reducing food waste. In addition to studying the possibility of implementing optical sorting in downtown Stockholm, the yielded amounts of energy from waste collection and reduced wastage will be calculated. This is done by way of literature reviews and interviews. The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil fuels, but the required food waste contributes to increased greenhouse gas emissions as well as reduced bio diversity and eutrophication during the wasted food?s lifecycle.
