Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of the plant. The basis in such a system is to make an energy mapping.In this thesis an energy mapping has been performed at the waste incineration plant with the aim to identify and determine the size of energy flows. The investigated energy flows are used fuel, produced and used steam, produced district heating and cooling. Also the use of electricity to run the processes has been investigated.

The purpose of this study was to describe how journalists do research for their articles and whether there is a need to create a knowledge bank of the material that journalists use for writing these articles. I also looked at how knowledge management could be used at a daily newspaper to add value to the information used by the journalists. The thesis is based on four interviews with journalists, a literature review and a practical project. I helped a journalist with his information seeking and later tried to organize the material. This project gave me an understanding of how varying the material that journalists use is and how difficult it would be to try to organize it in order to create an organizational knowledge resource of the material.

This Master degree project has been performed at the Braviken paper mill on papermachine 53 (PM53) which produces newsprint paper. The current economic situationhas contributed to declining demand for newsprint, which means it is extra important tobe competitive by high energy efficiency. Particularly as energy prices are expected torise when the economic growth returns.One way to increase energy efficiency is by reducing the water use in paper and pulpmills and consequently save energy through reduced heating of water. The thesis's maintask is to evaluate whether a water purification plant (microflotation plant) forpurification of process water in PM 53 is profitable. The microflotation plant enablesreuse of warm process water instead of losing the energy to receiving waters.

The purpose of the thesis was to map the hydraulic load on the Knivsta river from stormwater runoff, and build a platform for further studies of pollution loads on the rivers ecosystems. New residential areas are planned to be built in Knivsta municipality and it will have an impact on stormwater flows to Knivsta river. To examine the impact this will have, simulations were made in the area as it stands today and after expansion work. The work includes calculation of flows from the populated areas but also from the catchment area around it consisting of woodlands and fields. Because of expected climatic changes which may affect rainfall, the simulations have been performed with different return periods for rainfall data.

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

The upstream spawning migration of Atlantic salmon (Salmo salar) at the confluence area between the power-station outlet and the bypass-channel in river Umeälven (flow 430 m3s-1) was compared in 2004 and 2005, two years with different experimental flow-regimes. In 2004 the water flow in the bypass-channel was altered during the day with increased flows during the nights while the water flow in 2005 mainly was altered between the weekdays and weekends. Salmon showed altered migratory behaviour in this confluence area, assessed with telemetry (n=116) and echo-sounding, with up- or downstream responses depending on flow-changes in both the bypass and the power station outlet. Increased turbine flow through the power-station generally attracted salmon into the tunnel outlet area while increased spill-flows facilitated salmon to enter the bypass. Echo-sounding in the confluence area showed an increased swimming activity up- and downstream due to time in the day and flow-rates through the tunnel outlet. No changes in activity could be detected due to increasing or decreasing flow through the hydro-power facility.

The aim of this thesis is to map the current internal information flow at Volvo Uddevalla, to detect obstacles in the flow and to find out how these obstacles can be avoided. The aim is also to describe how a corporation, in this particular case Volvo Uddevalla, creates knowledge and use information. The study is performed in order to create a base for the coming implementation of a new information standard. The method used is conducting an information audit investigating the current management of documentation according to the changes that have to be made to carry out the claims from the standard. The investigation is made by way of interviews with 16 of the employees at Volvo Uddevalla.

The aim with this independent degree project of master thesis is to find what the user opinions of the intranet in a county council is. The paper seeks how the question about how the culture in the organisation was affected by the use of the intranet. An important part is to explore the expectations and acceptance of the intranet and get a picture of which functions and services support day-to-day work with good quality. One goal is to find out how the intranet users feel that the communication, information and usability can be developed.The focus group interview is a qualitative method that has been applied for gathering data from the respondents, who participate in the investigation from the county council. The used method is unstructured focus groups containing the three dominating categories of staff in the county council.

In the year of 2011, the new CEO of AB Volvo announced a major reorganization. This reorganization was a contributing factor to the start-up of this thesis.Volvo Group Logistics Services (VGLS) is Volvo Group?s global logistics partner, which designs, manages and optimizes all of the group's incoming and outgoing logistics flows. With the reorganization, VGLS started a project regarding responsibilities around railway flows. Within the project a demand to collect logistics requirements occurred.

Background ? The last 20 years healthcare has been facing increased demands on efficiency and increased customer satisfaction. This despite reduced resources and increasing demand. These demands are presents in all departments within healthcare organisations, including medical laboratories that currently receive an ever-increasing number of remittances. Laboratory flows are quickly becoming overloaded with samples and related materials.

Holmen Skog, region Norrköping, is located in an area with good potential for backhauling because a large number of geographically scattered mills. However, despite these factors there are many difficulties preventing the realization of this potential. The purposes of this study were twofold. First, from a hauling contractor perspective, to calculate backhauling profits and suggest a profit sharing scheme. Second, to identify and quantify obstacles and possibilities for realization of backhauls.The study required the use of three different types of methods.

In Eskilstuna and Sweden in general the level of reuse of surplus material containing soils and rocks from excavation is low. In this report the potential for increasing the reuse of excavated material in Eskilstuna by using a web-based earth information database has been examined. The purpose of a web-based earth information database is to connect those who have surplus material with those who need material for a fast and simple transaction. The intention is to give Eskilstuna a more environmentally and economically efficient handling of surplus material by increasing the level of reuse and thereby reducing the amount of surplus material that is wasted and emissions given off to the atmosphere during transportation. The potential has been examined in two different ways, by tracing information about a number of projects to see if excavated material driven to the dump could have been used in another project and by interviewing eight of the work leaders active in Eskilstuna.

A good flow of information in organizations is one of the key aspects of how we define a well-functioning organization. The information flow could be internal as well as external between actors within as well as outside of the organization. In a logistics organization this flow of information is equally important as in any other kind of organization. In this paper we have explored information flows in logistics organizations by applying, boundary spanning and the mobile-stationary divide perspective. In boundary spanning the main goal is to erase or relocate some of the boundaries within an organization, in our case to make the flow of information internally as well as externally better.
