Bildåtervinning för alla: Att tillgängliggöra bildsamlingar för en bred och ickespecificerad användargrupp.

This essay is a survey of thirteen user studies performed in the field of image retrieval. The purpose is to try to distinguish principles that should be kept in mind when wanting to make image databases available for a wide and varied group of users. The essay tries to answer two questions, namely: Are there any results in accordance among the different studies? What in the user studies should be considered when it comes to how content description, interface and functions for searching can be designed when creating systems for image retrieval? Each study is first reviewed on its own, and then a comparative analysis of all the studies is carried out. Derived from the result of this analysis, the conclusion is presented in the form of a row of suggestions to which aspects are to be suitably included in the design of image databases.

Hantering av QoS i Distribuerade MPEG-videosystem

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.

Askans inverkan på beläggningstendensen i ett biobränsleeldat kraftvärmeverk och växtplatsens påverkan på askegenskaperna :

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.

Miljöfarliga transporter till sjöss : Kartläggning och riskanalys

An increasing number of chemicals are being transported by ships along the Swedish coastline. Many of these chemicals may pose a threat to the environment. Accidents and spills are luckily rare, but nonetheless it is important to be prepared for a possible chemical spill. The Swedish Coast Guard is responsible for responding to chemical spills at sea, and has both equipment and trained personnel for the purpose. In order to prepare for a possible accident one also needs to know what is currently being transported at sea.

Förpackningshantering i det dolda : En studie om hur den interna hanteringen kan synliggöras och förbättras.

Handling materials and packaging, which is the focus of this study, requires efficient logistics, both internally and between companies. To achieve an efficient material flow, good information systems, whose role is to collect, store, process and distribute information, are required. The assumption that packagings are handled in an efficient manner is currently not a matter of course, when many companies do not prioritize the internal management of the package.The purpose of this report was to investigate how medium-sized businesses working with distribution and handling of spare parts packaging can improve their internal management of packaging. In order to answer the purpose, we have used an abductive process and a qualitative data collection. The study had Logistic Center Ljungby (LCL) at Electrolux Laundry Systems (ELS) as a case company and two other respondents, Nibe in Markaryd and Enertech in Ljungby.

Populärmusik i TV-reklam : En kvalitativ undersökning av musiken som betydelsebärande teckensystem

This paper examines a popular music song (Heartbeats by Jose Gonzalez) as a sign system in television advertising. The study was conducted through qualitative questionnaires in connection to an audio-visual method of analysis called Masking. The method facilitates the analysis of isolated parts in the audio-visual spectrum by masking/hiding parts of the audio-visual totality.The survey had seven respondents where a hermeneutic epistemological approach was used. For the analysis Cooper's theory of brand identity (Practical and Symbolic Attitudes to Buying Brands) was used together with an interaction model for music in audio-visual advertising called "Modes of music-image interaction?.

Utsikten : Hållbara uppvärmningsalternativ för vandrarhemmet på Finnhamn

Finnhamn is a small group of islands in the Stockholm archipelago. At Stora Jolpan, the biggest island, there is a hostel. The main building was built in 1915 and is called Utsikten. The purpose of this project is to on behalf of the Archipelago Foundation (Skärgårdsstiftelsen) find alternative systems that can replace the existing heating system of Utsikten (an oil-fired boiler and electricity heaters) to a system with renewable energy. The alternative system that this project focuses on is a system of solar collectors combined with a wood chip boiler.

Att mäta eller inte mäta? : En kvalitativ undersökning om prestationsmätningar på en av Blekingesjukhusets kliniker

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.

Undersökning av solcellspotentialen för golfverksamheter i Sverige

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.
