This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.

With new energy directives in place, the Swedish Social Service (SSS) stands beforethe challenge how to reduce the energy demand in its locales. It is a complex matter,as the locales are rented from various property owners and it becomes a question ofhow to reduce the operational electricity and influence the property owners to workmore with energy efficiency. This thesis takes a balanced research approach in threeparts. Firstly a qualitative part in form of interviews with personnel at the SSS and itsproperty owners, secondly a quantitative part of descriptive nature in form of energystatistics and thirdly a literature review of Energy Management (EM) Supply ChainManagement(SCM), Green Supply Chain Management(GSCM) and EnviromentalPerformance Indicators (EPI). This in order to be able to give normativerecommendations of how the SSS should act to reduce its energy Consumption in itslocales and provide new insights on how EM, SCM, GSCM and EPI can be applied ineffect.

Det är idag uppenbart att miljön måste skyddas för att kunna säkerställa en god livskvalitet även för kommande generationer. I samband med dessa frågor spelar byggsektorn en oerhört central roll, vilken kan hänföras till den betydande miljöpåverkan industrin har på samhällsutvecklingen idag. Byggsektorn, också kallad "40-procents-sektorn" i miljösammanhang, svarar för 40 procent av den totala energi- och materialresursanvändningen i Europa och den nordiska marknaden. Det är därmed tydligt att byggindustrin har en signifikant påverkan på individers livskvalitet och miljö, varför det är av största vikt att sektorn tar ett aktivt ansvar för en hållbar samhällsutveckling. Kunder har konstaterats utgöra en av den viktigaste intressentgruppen, som med dess miljömedvetenhet och kännedom utgör de främsta påverkande faktorerna till den gröna revolutionen.

AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy Consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.

Environmental problems are accelerating with energy Consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.

This study will identify the environmental impact in terms of carbon dioxide for a boiler house on behalf of Kvänum energi. The boiler central consists of a main building, which in turn contains multiple components such as boilers, pipes, etc, the boiler central uses pellets fuel. It also includes a silo and an ash container. The total weight of the boiler is about 63 tons. Each boiler has an output of 600 kW; the central includes three boilers with room for a fourth if necessary.

Konsumtion av etiska livsmedel tycks ha fått ett rejält uppsving under senare år och många sträcker sig så långt att de talar om en ny grön våg. Det konsumeras allt mer ekologiska, Fairtrademärkta, KRAV-märkta och närproducerade livsmedel. Men vad är skälet till att vissa konsumenter väljer att i princip uteslutande handla etiska matvaror medan andra är till synes likgiltiga, och kan det ha ett samband med hur hög grad av oro konsumenter hyser inför framtida konsekvenser av sitt köpbeteende?Vi har studerat hur studenters uppfattning av risk kan kopplas till deras köpbeteende i samband med etiska matvaror. Vår huvudfråga lyder ?Konsumenter som väljer etiska varor är mer oroliga för framtida konsekvenser av att inte förändra sin konsumtion än icke-etiska konsumenter.? Vi ville se om oro för framtida konsekvenser, i stil med miljöförstöring och hälsoproblem, kan kopplas till en ökad konsumtion av etiska produkter i syfte att ge en ny infallsvinkel till marknadsföring av dessa produkter.Vår studie tar stöd i en generell modell över risk kopplat till konsumentbeteende, framtagen av Åsa Boholm, vilken vi sedan har tillämpat på just konsumtion av etiska livsmedel.

Consumers today seek added value to the ordinary products/services that companies are offering. Consumers must get their emotional need satisfied - a need for experiences worth remembering. At the same time, the consumers are engaged in ethics and morals. Companies use events frequently as a marketing approach to meet the customer?s demand of added value.

This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

The economic development and competitiveness in Europe is heavily dependent on an efficient transport system. Movement of goods and people is essential for a competitive industry and successful trade. As a result of an intensified transport business, Consumption of fossil fuels has increased dramatically. As a consequence, there are increased emissions of dangerous greenhouse gases. Transports are often mentioned as an area with high impact on the environment.

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

World wide globalization and the rapid development of the Internet have lead to significant changes for companies around the world. The world has ?shrunk? and increased supply of goods and services has lead to a more intense competitive situation. As the market changes, so does consumer behavior. Today?s consumers do no longer wish to be treated as a group, rather they are looking for products and services that specifically fit their personal values.Recent years, the Consumption of digital consumer electronics has sky-rocketed.

The focus of our dissertation is masculinity which is often a topic of debate in today?s society concerning areas such as violence, sport and paternal leave. Male studies are a relatively new field which means there is a lot remaining to be explored. We have chosen to explore how social class reflects on male identity. The reason we have chosen social class as a variable is due to a focus in the general debate of identity amongst the social sciences towards identities formed through Consumption in the world of global mass-media.

Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.

To meet the growing amount of waste from electronic and electrical equipment (WEEE) EU developed, year 2002, a directive (2002/96/EG) with the objective to govern the management and reduce the amount of WEEE. The directive is based on producer responsibility which makes the producer responsible for collection and dispose of WEEE. In 2012 a new revised directive (2012/19/EU), with tougher collection targets, was developed. Both the old and the new directive states that the approach to tackle WEEE should be prioritized in order of prevention, reuse and then recycling. Hitherto the amounts of WEEE has increased every year, making it relevant to examine which type of preventive measures the directive contains and how effective they are.
