With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.

The purpose of this study was to investigate the reason behind thedecision by a company regarding the desire to use mobile access to theirERP-system and to discover whether this will involve any loss offunctionally in comparison to using the ERP-system on a computer atthe office. In addition, the pros and cons involved in using mobiledevices for accessing the ERP-system will also be examined. Semistructured telephone interviews were conducted with companies whicheither used or did not use mobile devices in relation to their work. Atelephone interview was also conducted with a consultant who isworking with the implementation of ERP-systems and mobile solutions.The survey showed that companies with staff working in the field assellers, service personnel and construction workers want to gain directaccess to their ERP-system so as to be able to act directly and takedecisions, to have the ability to provide more efficient order processingand to send out invoices more quickly. Those companies which have notopted to use mobile devices at work within this field are those whichare unsure of the connection to the Internet and the capacities availablewithin cellphones.

AbstractPurpose/Aim: This essay deals with The Swedish Red Cross Society and their work concerning strategical information and communication about HIV and AIDS in the Swedish context. In a broader sense the relation between the global and the local will be investigated and a discussion about what it means to work in an organization operating on a global arena will be held.Material/Method: This essay is based on relevant theories about culture and health communication which I have studied, selected and put together, with purpose to analyse The Swedish Red Cross Society and their informational work with HIV and AIDS- prevention. Furthermore I have interviewed four of the organizations co- workers to collect data about their experiences in working in the Red Cross organization with this specific mission. Moreover I and my colleague Hillevi Good attended at seminars and lectures to observe activities held by the organization and to get inside information about what people working with HIV and AIDS are discussing and considering as critical issues. The study holds a qualitative approach focusing on understanding this typical case rather then generalizing facts in a larger sense.Main results: The Swedish National Society of The Red Cross has a difficult mission in their work to inform the public about HIV and AIDS, although it is the perfect organization when it comes to communication due to their well-known profile and a huge geographical spread.

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.

In this report a study has been done regarding different heating systems on which are the mostcomprehensive with solar heating systems. The report has also been focusing if solar power can beused as a primary heating source for supplying more than 50 % of the buildings total heatingproduction. The University of Dalarna constructed a demo-house for this purpose and according tocalculations the total solar usage is more than 50 %. This house has been made for referenceregarding the design of the heating system of property 5:37.Further studies have been made to compare different heating systems that are compatible with asolar system, where the compared systems purpose is to be independent of direct using electricity. Asystem of this design is regarded as sustainable according to environmental as economic issues.

Blekinge Hospital suffers from a budget shortage of 100 million SEK, while the government now requires that hospitals will no longer be running a deficit. Blekinge Hospital will then use their limited resources to survive in the future and the activity must be enhanced in order to keep costs low without having to lay off personnel. The idea is that the organisation should be more efficient with a more efficient resource usage. Performance measurement systems are important tools for achieving the policies set out within an organization, measuring and evaluating performance is a way to see where improvements in efficiency may be necessary in the business. Balanced Scorecard (BSC) is one of several measuring systems, where the focus is on measuring non-financial performances.

Stratego is a boardgame not very different from chess, that contains hidden information. Because of this, existing programs play at beginner level. The purpose of this thesis is to adjust a minimax algorithm so that it passes the demands of Stratego, and then build a Stratego agent around it. Tests with existing minimax algorithms leads to the development p-e-minimax. This algorithm uses two different values in its nodes to simulate the different information available to the agent and its opponent.

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT). The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done. The results showed that GIT will make the harvesting managers work easier.

The authors of this thesis have studied the handling of personal information in various kinds of organizations, because the perception is that the knowledge in this area is weak relative to the weight of the subject.The purpose of this paper has been partly to shed light on how knowledge of this area in the organizations that we have visited during the study but also to answer questions about handling, knowledge and security, and identification of individuals in different systems. What kind of problems the processing of these data creates and why these problems occur.In the beginning of our study we understood the importance of using the correct identifier and therefore chose also to examine what the various identifiers used by the organizations and why they chose these particular identifiers.In the qualitative analysis, Datainspektionen´s general rules and advice has been used as a basis together with the laws applicable to the organizations to get a good picture of how management of personal information is in these organizations.What we have found in this paper is that knowledge about how personal data is handled and what laws and rules are saying is very much dependent on how central the information is to these organization's activities. The police use so many different types of records for their organization to function well and they have very good knowledge of laws and regulations. In contrast, schools that do not handle as much of personal data themselves nor have the same knowledge among staff and do not have enough resources to cope with keeping the same knowledge base as the police. This is something that applies to all types of handling, depending on how important the information is for the organization, the better the security and knowledge in handling the data is..

Photovoltaic Systems in Sweden has longbeen heavily dependent on subsidies and grants to bring in a profit for the investor. Production of excess electricity is a major reason for this as the compensation for excess electricity today is low. However, there are businesses that have an electricityneed that are particularly suitable for solar electricity. These businesses have an electricity demand when the sun shines the brightest and if the Photovoltaic System is properly scaled, the excess electricity can be minimized. A golf club is that kind of a business and this thesis aims to examinate the solar power potential for golf businesses in Sweden.Nine golf clubs was selected from different locations in Sweden.

Article 4.1(h) in the Rome I regulation establishes which law that will be applicable on contracts concerning financial instruments concluded in multilateral systems. The main problem is that most contracts concluded within these systems have standard clauses which contain a clause on the applicable law. If this is the case, Article 3.1 in the Rome I Regulation is applicable instead. This problem makes it difficult to find a need for article 4.1(h) if it will only be applicable in exceptional cases. However, the legal position on this matter is still unclear since the Rome I Regulation has just been put into force.

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.
