Då webben nu består av dynamiska hemsidor och kraftfulla applikation blir ävenkraven på kommunikationshastigheter större. Detta arbe har tittat på den äldre ochpoppulära tekniken Long Polling och ställt den i förhållande till HTML5s nyawebsocket API. Igenom att bygga ett multiplayer spel för webbläsaren utan någrapluggins ställdes teknikerna mot varandra för att se vilken som presterade bäst ochvisade sig mest effektiv för användning i den typen av applikation. WebSockets visadesig klara av alla tester med marginal mot de värden relaterad forskning visat på ärminimum kraven för att kunna realisera realtidsapplikationer. Long Polling föll kortoch visade sig vara svagare på alla punkter i förhållande till WebSockets..

During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

The market for security is one filled with great opportunities. The security services companies are numerous and diverse, the Swedish market is dominated by two large companies: Securitas Bevakning AB and Falck Security AB. In this study we have focused on the bigger of the two, Securitas. This report describes and analysis the security service branch and its surroundings in an involved manner. The target group of the result is mainly people within the security branch.

The Swedish Migration Board has during a long time had problems with long processing times for persons that apply for asylum. The government has set targets that investigation should not exceed 6 months although it is done in almost 70% of cases.The study's aim has been to examine if steering can be linked together to long processing times and, if so, explain why. The intention has not been to provide a comprehensive picture of the problem but has defined itself to ensure steering impact. The study has been carried out by studying relevant governing documents, previous research and by interviews with administrators and decision-makers in two of the Migration Board asylum units.The analyses of the study show that a combination of inadequate steering and inadequate resources have contributed to aggravate the implementation, which has lead to long processing times..

Syftet med föreliggande uppsats var att med utgångspunkt i Chris Andersons bok The Long Tail (2006) skapa förståelse för begreppet och fenomenet Long tail. Vi avsåg vidare att belysa dess modus vivendi, sätt att vara, genom att undersöka och teckna en bild av den kontext eller diskurs inom vilken Long tail skulle kunna existera. Slutligen fördes en diskussion utifrån en egen analysmodell gällande begreppets eventuella räckvidd. Chris Anderson har med fenomenet Long Tail i det närmaste sammanfattat en rad olika tendenser eller strömningar i vår samtid och uppmärksammat en ny marknad som växt fram som ett svar på den digitala tidsåldern. Long tail kan i princip förekomma inom alla branscher där det finns en fördelning mellan produkter med hög respektive låg efterfrågan.

Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential enrichment objects on piglet?s behaviour and weight gain during the pre- and post-weaning period. The second aim was to examine what type of object stimulated the highest frequency of interaction. The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used.

This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.

The foundation for a museum is the collection. To collect, preserve and display is what constitutes a museum. But the process of deciding which object´s should be saved, and which objects should not, are based on values. It is also values that make people inclined to donate objects to museums. How and why we value a museum determine if and why we donate.Objects themselves could be said to have a biography just like people.

The object of this essay was about youth's experiences of their possibility of consumption. We also wanted to analyze if their possibility of consumption had a connection with their experience of happiness. Another part of the object was to see if there where any differences between girls and boys concerning the questions above. One of the issues we had was if the youth's money was enough for their needs of consumption. The method we used were a questionnaire, which we asked a class of 22 pupils to fill in.

The work related illness has increased and instead of focusing on what?s causing it more and more efforts are put on trying to find the health factors within and outside the work environment. During the past years the term ?long-term health? has arisen; instead of focusing on the number of employees on the sick-list, the focus should be put on the number of employees that has a record of long-term health within an organization, i.e. health-presence.

certain building or environment can get a protection as a notable building if it contains certainvalues. These values are established by a certain category of people from the cultural sector.These people use established criterions to define the cultural value of the object. The objects canbe evaluated differently depending on who has done the evaluation. The people who protect thecultural environment and choose which buildings that are to be defining as notable buildingsoften uses a special model to characterise the different cultural values. This model is produced bya man called Axel Unnerbäck.

Metaphors and their use as a rethorical vehicle are examined. Two texts, one in Chinese and one in Swedish, are compared and analyzed to determine the extent to which the associations they create successfully capture the author's intent. Seecondarily, a shift from the assumptions that rhetorical analyses often assume (read: antiquity and Aristotles) to a more abstract internal human platform is suggested. Neurological and cognitive research is cited in support of this shift.The essay examines the question: How can metaphoric contribute to conveying the communicator's intention? By comparing metaphorics used by an historical Chinese rhetor with those used by a contemporary Swedish rhetor.

The purpose of this study is to examine the changes in law and other types of politicialregulation regarding unauthorized absence during the reformation of the Swedish schoolsystem in 2010. How was this ?new? approach on unauthorized absence established; whatmade it possible and which view on ?unauthorized absence? does it implicate? The study hasa discourse analytic approach in which it examines central policy documents regarding thetopic of inquiry. The study has found that the alliance-government?s education policy onunauthorized absence is pervaded by one hegemonic discourse termed the mono-culturaldisciplinary discourse.

The report handles the transmission of signals from piezoresistive pressuresensors and thermocouple from a rotating object. This report also evaluates the possibility to collect data in a datalogger that rotates with the object. Telemetrics was previously used for signaltransmission in Finspång, therefore there has been no tests considering preassure measuring. One transmitting method handled in this report is transmission through a slipring connection. One test with a slipring connection was performed for transmitting signals from a piezoresistive preassuresensor.
