Streamlining Streaming : Tilläggsfunktioner och dess betydelse för att designa en streamingtjänst
Streaming is a big field in todays digitalized society. The streaming market is huge, both in regards to the customer base, but also in regards to different providers and their stakes within this market. But how does the different providers go about in order to provide their users with added value? What does the user prioritize? The purpose of this study is to examine which additional functions can be considered important when designing a streaming service, which in turn will create an added value for the user. The study is based on a qualitative study of 6 individuals with semi-structured interviews and we will present an in-depth analysis regarding four fields of interest to us in regards to streaming services; second devices, recommendation systems, keywords and social connectivity.
Gilla, dela och kommentera ? Användarrespons på bibliotekets Facebookinlägg
The focus of this thesis is to examine posts on library?s Facebook pages and to investigate possible connections between posts and user response. The study examines posts published from thirty different libraries Facebook pages over a two week period to examine if any correlation between different subjects or types of posts affects the degree and type of response from the users.The findings show that photos stand for the majority of the published post concerning its type and that activities at the library was the most common subject of posts. After using eta as measure of association a tenuous connection between degree of response and the posts subject and between the degree of response and the type of post was found. The standard deviation, however, was high in the majority of the variables used.
Prestanda och precision pa? en enkortsdator i ett system med realtidskrav
The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.
Utvärdering av laddningskoncept för lastbilsbatterier
When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.
Oäkta Goodwill: Den oäkta goodwilldelens effekt på nedskrivningar av koncerngoodwill
Since January 2005 new rules have been introduced from the International Financial Reporting Standards for accounting of Business Combinations. Goodwill, which is the difference between the purchase price and the value of the net assets in an acquired firm, should no longer be amortized but should instead be treated as an object for yearly impairment tests. Nevertheless, there are many companies making the tests but not impairing goodwill. The theoretical frame of reference looks at goodwill from its two parts; true goodwill and false goodwill. False goodwill is defined as a measurement bias and constitutes a certain percentage of the operating net assets.

C?RONIS BIVAXFERNISSA En unders?kning av inneh?ll, l?slighet och ?ldringsegenskaper
The aim of this study is to provide a comprehensive overview of C?ronis beeswax varnish by Lefranc &
Bourgeois; its contents, aging properties, solubility, and possible removal methods, with G?teborgs
Konstmuseum?s ?Gothenburg Museum of Art? collection as the stud??s material? The purpose of the
study is to provide a basis for decision-making regarding the treatment of works treated with C?ronis
wax varnish. The study is based on contemporary conservation theory and interpretation-based
decision-making and utilizes FTIR, microscopy, and solubility tests to examine the properties of the
varnish. The study shows that C?ronis does not appear to be harmful to the treated works and has
retained its solubility properties and transparency over time.
Visuellt typinstrument : en metrologisk studie
Visual Type Instrument - VTI, is a tool containing a typeface and a set of geometric calculations that generates numerical data in spreadsheets. The data is determined from the typefaces visual dimensions and is used to calculate leading, type size, margins and format. The aim is to offer, for all of those working with typography and design, a practical way to manage text, image and format in relationship to visual size. Instead of using point measurements, VTI uses a new device called Edo. An Edo is the same as one twelfth of a millimetre.
Mätning av Mikroläckage i Dentala Implantat
Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss.
The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.
Utvärdering och implementering av automatiska farthållare i fordonssimulator
Vehicle simulators are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before.In this thesis the building of an vehice simulator will be described and a comparison between three different cruise controls. The three cruise controls are PI-regulator, a regulator who regulates after positions in the terrain and a MPC-regulator. The reason for choosing this three is to see the difference between simple regulation and more complex regulation with respect to fuel consumption, travel time and complexity.The vehicle simulator is made in Matlab/Simulink, Visual Studio and Open Scene Graph.
Identifiering av designriktlinjer lämpade för integrerade videouppladdningstjänster
There is a lack of published material regarding designing graphical user interfaces of so called integrated video uploading services. The term integrated video uploading services refers to homepages that do not have video uploading as its primary purpose but which still offers that service to its visitors. The aim of this thesis was to improve the amount of published material about designing graphical user interfaces for integrated video uploading services. This was done by performing a literature study to find general design guidelines which can be applied to design of integrated video uploading services. Thereafter the functionality and design of dedicated video uploading services was analyzed.
Representationer av migranter inom biblioteks- och informationsvetenskaplig forskning : En textanalys utifrån kritiska ras- och vithetsstudier och intersektionell teori
The purpose of the essay has been to examine representations of immigrants in contemporary library and information science research in a Scandinavian context. By analyzing nine articles from the past decade we examine the perceptions that exist in the concepts of multiculturalism, culture, race, ethnicity, religion, gender and whiteness and what role and importance the library as a place is assigned in relation to immigrants as a user group. Our study consists of a qualitative text analysis, a critical oriented close reading method based on critical race and whiteness studies and intersectional theory. We have, with the help of Sara Ahmed´s theories of hegemonic whiteness, demonstrated how multiculturalism is partly presented as something desirable and good, partly as something potentially threatening.The discourse of multiculturalism can be said to express the notions of the other, which in the source material manifests itself by ascribing otherness to immigrants. We have, for example, examined how ethnical and cultural differences are highlighted by a separation of East and West, the library?s educational and assisting role in relation to immigrants as a user group as well as representations of whiteness, gender and clothes.
Utvärdering av en väggkonstruktion utan PE-folie : Med en undersökning av hårdvaxolja som diffusions-/konvektionsspärr
District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.
Hundratusen rullar fram i Sverige : Det enda som stoppar rörelsehindrade är omgivningen
Service Design is a relatively new, unexplored and exciting phenomenon that through an interdisciplinary work methodology designs services. A discussion has been going on for a long time regarding whether there is a difference between products and services. Services are often classified as immaterial, heterogeneous, non-storable and inseparable in relation to products. A question that arises is if something specific characterises the work methodology used regarding service design. The aim with this paper is thus to explain the work methodology when working with service design.
