A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

In Sweden, there has been a continuous increase in the volume of housing construction for dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.

AbstractAt the UN Conference on Environment and Development in 1992 the nations stated that traditional environmental policies were not sufficient to handle the multidimensional challenges posed by sustainable development. Governments needed to broaden their political decision making procedures in order to coordinate and integrate environmental, social and economic policies. Therefore a new tool was introduced in Agenda 21, National Strategies for Sustainable Development (NSDS). The aim of an NSDS would be to bring together actors from all parts of society to jointly reach a consensus on how to work towards the vision of a sustainable society. An NSDS would be seen as a strategic tool to help focus national policies for SD.

Background: Risk Management plays an important part of the enterprises strategic business activity. Efficient Risk Management will secure the businesses survival, assets and creates market advantages. The interest of information security has consequently gained in Swedish corporations. Corporations have realized the importance of the information which is stored in the IT systems. IT is the tool for businesses future progress and growth and therefore a source of risks.

The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

The paint market of today is a jungle whit an enormous range of different paint types; there all has different properties and different compositions, some with big influence on the environment and some whit less influence on the environment. It could even be difficult for an expert to always know what should be used on which surface and what would be the best out of the environmental point of view.This work is not intended as a total review of all the manufactures range of colours; only as a deeper dissertation about distemper paint in general, in particular Falu Red Paint. Whit focuses on the environmental issues.The work is especially for those who are ready to paint but don?t know what paint they should chose and people that has a interest in paint and environment, perhaps it also could be of interest for professional painters even when there probably isn?t any big news for them. The information is compiled from the Internet and downloaded brochures from the Internet..

This study investigates communication and data in information systems. The paper deals, more specificly, with communication in a CRM-system implemented in a Swedish-founded company in Beijing, China. It discusses cultural, political, linguistic and gender based dilemmas that can arise from the use of a CRM-system in an international and bilingual environment. Fifty-nine interviews were conducted in Sweden and in China, either in Swedish or English. The result of this study shows that communication in the information system is affected by factors, that are not originated in technical shortcomings of the system, but rather from cultural, political, linguistic and gender based pre-knowledge among individuals.

The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.

The purpose with this study is to compare different systems of grain storage from a financial point of view. Grain that is supposed to be fed to laying hens. The systems that were compared were different airtight storage of grain and a system of conventional storage. To make this case study I choose to compare four different systems. In the case study there was one system with bin drying of the grain, two systems with airtight storage of the grain and one system where you buy dried grain during the season. I made several of capital investment appraisal where I found the cost of each system, then I took the cost and divided it with the total grain use and calculated the cost for each kilogram of grain, and also the cost of the feed. Then I compared the cost from my case study with the cost of buying feed. All the systems except for one, gave a lower cost for the hen feed than buying feed from a dealer The best system, witch were bin drying lower the cost with about 80 000:- SEK.

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

As the ability to computerize processes and tasks increase, the proliferation of complex systems in our society continues. How these systems are deployed in the organizations where they are meant to be utilized has been shown to have a large impact on how well they function.In January of 2011 the Enköping hospital initiated the deployment of an IT-support for drug management, a module in the general health care system Cambio COSMIC. Other health care providers in the county, and in the rest of Sweden, have had mixed feelings toward the module. Some have outright refused the module, claiming that it is detrimental to patient safety. One of the arguments for deploying the module in Enköping, however, was that it was needed to improve patient safety.The Enköping hospital is considered to be a well organized institution with good leadership and earlier good experiences regarding IT-systems.
