Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.

The tourism industry is growing and with its growth competition between destinations rises. In competition, cooperation and collaboration between tourism operators seem beneficial when creating an attractive and dynamic tourist destination.The purpose of this study is to describe and discuss the significance and influence of tourist related networks at a tourist destination, and therefore this study aims to examine the question: What significance do the tourist related networks have at a tourist destination?This study focuses on seven networks on Gotland that are tourism related, and the representatives of the networks were interviewed in order to get their view on the network and its significance to the destination. The study shows that networks have an important role in creating a unified tourist product of the destination, and in reaching out to the potential visitors through joint destination marketing. The study also shows that the tourism related networks helps to improve the reception of the tourist at a destination and to secure the quality of the tourist destination and its tourist products..

Background: Good communication is very important for the safety of patients in emergency situations. Few studies have been conducted regarding communication among health care staff. The aim of the present study was to investigate anesthetist nurses experience of communication among health care staff during a situation of emergency in a hospital ward.Methods: The study is explorative and based on interviews with six anesthetist nurses. A qualitative content analysis was used as an analyses model.Result: The six anesthetist nurses experienced structured communication as of great importance during an emergency situation. Three main categories appeared from the material: i) the importance of the organization ii) communication structure and communication patterns and iii) education and experience with nine subcategories.

The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.

Individuals considered as tax residents in Sweden may if they are working abroad for six months alternatively one year be granted a tax exemption concerning the income originating from the work abroad. Short intermissions (kortare avbrott) are permitted without impact on the tax exemption, however this requires that the intermission is not placed in the beginning or in the end and that the stay in Sweden does not exceed 72 days a year. A time limit regarding intermissions in a third country is however not regulated. There-fore the Swedish tax agency (Skatteverket) has published a non binding standpoint which regulates the entire intermission allowed to a maximum of 96 days a year whereof 72 days may be spent in Sweden. The definition is more extensive than earlier and uncer-tainty occurs as to whether the extension contradicts the principle of legality.The purpose of the thesis is to investigate the value of the Swedish tax agency?s stand-point concerning short intermissions.

Unjustified enrichment is used as legal basis when a part claims compensation. Unjustified enrichment can be illustrated as: (A) made a profit on someone else?s loss (B) and if the profit is"unjustified"and has"no legal basis"it shall be returned, which then make it possible for B to claim compensation from A referring to the profit. B has in this case lost something that he owns. To be able to claim A for compensation must the loss of B also be a benefit for A.

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

This report describes how we, with support from SYSteam Datakonsult AB Värnamobuilds a dynamic website for a fictional company. The purpose of this work is to tietogether our studies with the businesses in the region, and expand our knowledge.Together with Peter Bäckrud from SYSteam we worked out the goals to achieve thispurpose. The goals are to create a polished intranet to a company with the webpagepublishing tool EPIserverThis report begins with describing the goals and visions that were set up. Then follows athorough theoretical background that describes the areas we have touched, to give thereader an idea about the work. The report then moves into the creation phase that talksabout the problem that occurred during development.The creation phase is split up into two parts where the first part gives a good descriptionabout how we designed a usability friendly website that would fulfill the goals we had setup.

SammanfattningDetta examensarbete har haft till syfte att ta fram nya metoder för automatiseradtestning och validering av information som skickas över CAN (Controller-Area-Network)i en tung Lastbil. Signalinnehållet realiseras i flertalet komplexa och distribueradesystem. En implementering har gjorts där loggad CAN-trafikdata från en HIL (HardwareIn the Loop) miljö automatiskt analyserats och testats.Testen har genomförts på två nivåer: funktionell och ickefunktionell. Där denickefunktionella delen har testat tidkrav på meddelanden med kompensation förtändningsstörningar. Dessutom har signalinnehållet testats för att finna ogiltigafelflaggor.

For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

Idag är det kustnära eller det s.k. litorala området i fokus för många av världens mariner. Det finnsolika syften med att genomföra operationer i det litorala området men det huvudsakliga syftet äratt tillse att sjötransportförbindelserna som till största del sker i det litorala området fungerar.Andra syften är t.ex. att med expeditionära styrkor kunna påverka en situation på land eller somSverige operera i det litorala området i syfte att försvara sig. De uppgifter som ska lösas i detlitorala området inkluderas av begreppet Littoral Warfare, men vad betyder det för de olikanationerna?Denna uppsats jämför hur USA, Storbritannien och Sverige ser på det litorala området ochbegreppet Littoral Warfare.

AbstractIn my study I have investigated how a constructed outdoor green environment can beused, managed and how it works. The study also investigates the concept of socialsustainability, where, for example, civil dialogue is a method to promote this. Thisinvestigation mainly gives account for the inhabitants viewpoint but also a gardenersperspective. The study focuses on the planning process of the study object, what theoutcome has been and how the users of the green environment, think about the result. Inthe process there has been a strong concern of involving the residents and others usingthe area.

Democracy is said to uphold the dearest values and be the most moral system. But it cannot be characterized as a rigid "syste" but a continuously changing political framework, under which aims and values can be fulfilled - and replaced.The increasingly diverse and ever-changing environment of contemporary democracies forces change upon the systems' natural evolution, which makes their future features uncertain and unforeseeable. A powerful change-force doctrine does however claim change is mainly (or merely) caused by the power of ideas; the elite power over ideas can thus provide a natural foundation for the analysis of the direction of development for democracy. This study aims to provide such a foundation by reconstructing empirical and normative descriptions of democracy at two certain points in time, following extensive government studies.As a tool for analysis, this study identifies values of substantial and procedural character central to democracy theory and discourse. It further creates ideal types of democracy based on these values, to which the nature of democracy is measured.

In inhalation anesthesia life-support systems are used to provide gases to the patient and to monitor important parameters. These systems are used in dynamic and stressful situations where the information-load on the operators often is significant. This thesis presents a design concept of an anesthetic system. The design goal has been to keep the information-load on the operator low with the objective to minimize confusion and error.A number of contextual inquiries were made in the operating room during surgery at four hospitals in Sweden. The goal was to understand the actual use-situations when anesthetic systems are employed.
