Värmeväxling med torkluft från Valmets pilotmaskin TM1 : Återvinning av spillvärme vid torkning av mjukpapper

Idag ställs stora krav på företag att vara miljömedvetna och resurseffektiva i sin verksamhet. Vid mjukpapperstillverkning används stora energimängder och inom industrin har det under många år funnits en strävan att energieffektivisera processer och att tillvarata spillenergi, bland annat genom värmeåtervinning. Valmet Tissue Technology Center i Karlstad har idag en pilotmaskinen utan värmeåtervinningssystem. Den här undersökningen gjordes i syfte att ta reda på hur stor återvinningspotentialen är för värmeväxling i pilotmaskinens torkpartier, bestående av Yankeekåpan och TAD-cylindrarna. Tre maskinkoncept undersöktes: DCT®, NTT? och TAD.

Förutsättningar att utforma stationsbatterier i vattenkraftverk med Li-jonteknik

In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.

Brytningstid i Internkommunikationen? : vilken roll har Intranät och e-post i organisationers kommunikation?

Having a functioning internal communication is necessary for the survival and existence of every company. Traditional communication channels are for example meetings, noteboards and personnel newspapers. During the last ten years we have witnessed an explosion of new channels, who are based on information technology. IT is a natural part in new IT-companies, like Framfab and Icon Medialab, but what role does IT have in a large, manufacturing company with a long history? The purpose with this thesis is to investigate how IT has influenced the internal communication in a company.

Riskanalys av transporter med farligt gods i Vänersborgs tätort samt riksväg 45

Årsskiftet 2003/2004 trädde Lagen (2003:778) om skydd mot olyckor i kraft. Därmed upphävdes Räddningstjänstlagen. Lagtexten kräver att kommuner skall upprätta en riskhanteringsplan för tänkbara olyckstillfällen. Vänersborgs kommun har beslutat göra så och en del i detta arbete är att sammanställa en riskanalys. Denna rapport innehåller en riskanalys för farligt gods inom Vänersborgs tätort samt riksväg 45.

Integrering av pelletsfabrik med Rya kraftvärmeverk i Göteborg : en teknisk och ekonomisk utredning

Göteborg Energi has a surplus of district heating during spring, summer and fall. The heat surplus is due to a constant production of waste heat from oil refineries and heat from waste incineration over the year. It would be desirable to increase the demand for heat and the uptime for the newly built combined heat and power generation plant, Rya Kraftvärmeverk. One alternative could be to integrate Rya Kraftvärmeverk with a pellet production facility. By producing heat, electricity and pellet in a joint process the energy use can be decreased.

Nedskrivning av goodwill

The purpose of this study has been to examine how customers, by interacting with each other, can communicate and create the image of a brand. We find this topic to be relevant since there are no previous studies conducted concerning the customers influence on the brand image. Our ambition has been to describe in what ways and to what extent the customer can affect and influence the brand image by communicating with other customers. To fulfill our purposed we have targeted three important questions which are:? In which ways can the customer affect the communicated image of a brand?? To what extent can the customer influence the brand image and the perceived value?? Who has control over the brand, the customer or the company?For this study we have used a qualitative approach in which we have conducted eight personal interviews with brand consultants and the editor of the magazine Dagens Media which has given us the foundation for our analysis.

Med informationskompetens som mål en studie av den pedagogiska verksamheten på Karolinska Institutets bibliotek

The explosion of information technology has given users direct access to an ocean of information. Increased availability puts increasing demands on the ability of students and researchers to search for, filter, and structure information. In response, the role of the research library has shifted from being primarily an information resource to being an educational resource with a focus on teaching users what is known as information literacy. This thesis is a study of user-education at the Karolinska Institute Library KIB, the largest medical library in the Nordic countries. KIB has invested significant resources in developing user-education, and has a full-time user-education developer and a formal pedagogical platform for user-education.

En deal om dagen - En kvantitativ studie om hur konsumenter uppfattar varuma rken som promotas genom dagliga deals

The relatively new phenomenon of daily deals has had an amazing explosion of growth during recent years. The concept relies on offering deeply discounted products and services that a number of customers must buy in order to acquire this discounted service. Companies spend valuable resources on marketing to get customers but the effects of daily deals on the brand do not have empirical evidence. What is the customers' attitude towards companies that communicate through daily deals How is their intention to buy from that company affected This is what is the main purpose of this study. To examine how customers perceive a company, in terms of attitude toward the brand and buying intentions, when the company markets through daily deals compared to more traditional promotion.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

Kopieringsskydd: Hur skapar vi balans mellan användare och näringsliv?

Den här studien ämnar försöka reda ut delar av konflikten mellan näringsliv och konsument när det kommer till kopieringsskydd av datorspel. I dagens samhälle så finns det stor debatt om olaglig fildelning och dess betydelse för näringslivet. Vi har tänkt oss att det måste finnas en bättre lösning på problemet än att utveckla bättre och bättre kopieringsskydd så vi tänkte försöka hitta skydd som skapar en balans mellan fördelar och nackdelar för näringsliv och konsument så att båda sidor gynnas ungefär lika mycket. Detta gör vi genom ett antal intervjuer med näringslivet och sedan ett antal intervjuer med konsumenter, vi kommer sedan att dra fram fördelar och nackdelar för båda parter för varje kopieringsskydd som vi har valt ut att testa. Vår huvudfokus ligger på balans och vi har använt oss av Grundad Teori för att få fram vår teori utifrån de intervjuer vi har haft.
