In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Volvo Construction Equipment is a world leading company in construction machinery. Tomaintain the best products, development is prioritized. The master thesis regards sound reductionof the hydraulic system on a wheel loader. The background to the master thesis is asimulation made on the hydraulic system, performed autumn 2005. The result of the simulationshows that the energy of the pressure ripple is reduced when the paralleled hydraulicpumps are phase shifted and reduces each others pump pulsations.

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

Eco-design is all about improving products environmental performances throughout the products lifecycle by including the environmental aspect into the product development process. There are a large number of different tools that can be used for this, but there are several factors that can affect which one will be the best to use. Some tools for eco-design takes comprehensive studies and can only be performed by experts, while some tools can be used more time- and cost efficient and with basic knowledge. The choice of tool should be based on the company?s situation.This report describes the research of how the design and furniture company Blå Station could include a tool for eco-design in their product development process.

I en global värld där närmaste konkurrenten bara är ett musklick bort från den potentiella kunden är behovet av att kunna marknadsföra på ett bra sätt elementärt.Försäljaren vill behålla befintliga kunder inom företaget och behovet av att göra sighörd har ökat betydligt. Detta har bidragit till att en ny marknad vuxit fram med stöd från informationssystem med funktioner som tillhandahåller möjligheten att rikta sin marknadsföring mot en speciell kund. Systemen kallas CRM-system, CRM står för Customer Relationship Management. Många större organisationer känner behovet av att införa denna typ avsystem i den egna organisationen. Kompetensen och insikten om vilka förändringar ett CRM-system innebär för organisationen är ofta mycket låg och införandet resulterar ofta i utebliven framgång.

CML Data AB is a small IT-company that offers complete IT-solutions adjusted to the needs of the customers. It is hard for the employees to bring all necessary papers, files and software when visiting a customer. They also have difficulties planning their daily work and to keep track of each other, because of the lack of a shared calendar.The purpose of this report is to answer the following questions:- How do you develop a centralized information system for CML Data AB where it is possible for the employees to gain access to files, plan their days and where the customers can get access to relevant information?- How do you develop an information system that is easy to manage?- How do you make it easier for the employees at CML Data AB to update their homepage?We discussed the problems and the future information system with the employees and were able to establish a set of needs and requirements which we then used as a foundation during the software development. We used user centered system design during the whole process and focused a lot on usability and interaction design.The project resulted in a stylistically pure and user friendly portal.

Delegation of assignments regarding the work environment is a complex topic that is difficult to illustrate. It is not explicit mentioned in the law and the established practice are ambiguous and vague. This has caused a lot of confusion, not only for private companies but also for executives within public administration.Metso paper Karlstad Inc. gave us the assignments to investigate their delegation system and to analyze the need of change before a planed readjustment. The purpose of this essay is therefore to investigate how the proposed delegation system is constructed and whether it fulfills the demands established by Swedish law.

The crisis on Wall Street. This essay is a comparative study of how two business newspapers report on the bankruptcy of Lehman Brothers Holdings in September 2008. Seven articles from the Swedish European financial newspaper Affärsvärlden (Business World) and five articles from the Chinese-Asian news agency XINHUA FINANCE are examined. The aim is to analyze, understand and evaluate from a rhetorical perspective. My thesis is that rhetors storytelling can tell us more about how we cope with crisis in the global economic discourse. The texts can portray man as a narrative creature when identification as a rational actor is not enough. The analytical methods used are linguistic analysis with an emphasis on metaphor analysis, narrative analysis based on pentad - Critical dramatism, and discourse analysis with doxological outlook. The results show that both newspapers seek to defend the global economic discourse, but they do so in different ways. Affärsvärlden advocates calmness and conveys a cautious attitude. The heart of the crisis, as well as its solution, is on Wall Street. XINHUA advocates control and expresses confidence in authorities and the system. Asia is presented as Wall Street's savior..

The purpose of the thesis is to compare Sweden's and Great Britain's total costs for their systems regulating producer responsibility for waste packages. Producer resonsibility is a strategy implying that producers are responsible for their waste also after its use. Sweden and Great Britain introduced different systems systems after an EU directive was adopted in 1994 (94/62/EC), and they have resulted in entirely different recycling levels in the two countries. In the Swedish system, responsibility has been delegated to the industry who are responsible for reaching the determined goals. The economic instrument used is a fee, set and managed by the industry. The British system is more centrilised, and the economic instrument used to finance recycling of waste is a system based on transferable permits. The thesis compares the four different alternatives: delegated and centralised methods, and fees and transferable permits analytically.

Förväntad effekt av vårdens elektroniska IT-system är ökad patientsäkerhet, vårdkvalitet och tillgänglighet. Ett första villkor för att kunna uppnå detta är att IT-systemet används. I denna studie granskas ett underutnyttjat IT-system, använt för informationsöverföring mellan olika huvudmän vid samordnad vård- och omsorgsplanering.Granskningen baseras på teorier om hur individers intention och vilja till att använda ett IT-system initieras eller upprätthålls genom omgivningens påverkan.Resultatet visar att IT-användare i den patientnära vården (mikrosystemet) saknar adekvat tekniskt, organisatoriskt (mesosystemet) och ledningsstöd (makrosystemet), vilket kan förklara underutnyttjandet..

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

This report gives an overview of applications of the Greenroads rating system whichin turn is an environmental review system for roads. The focus of this report isapplications during the construction phase, ie on solutions which adhere to theentrepreneur's area of responsibility as opposed to the designer's. The study was undertaken in cooperation with Skanska (a global contractor andFortune 500 company) which provided a project suitable for an exemplatory study ofGreenroads. Please note that the project in particular was not specifically designedwith Greenroads in mind. Therefore and because of that the site provided anexcellent opportunity to study effects of application contra non-application. The approach of this study was to first review the system, thereafter to performinterviews with key personel at the site in different roles as to receive different viewsof selected points of application. Selected possibilities of application are cathegorizedand presented with comments and suggestions for adoption. Lastly Greenroads is briefly compared to the rating system which today is the mostwidely used by Skanska, LEED.

A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.

MPS-system syftar till att öka intäkterna, minska kostnaderna och frigöra kapital genom ökad leveransservice, flexibilitet och reducerade kostnader för lagerhållning, administration och transporter.
