The case study we conducted describes market for transmission of terrestrial digital TV. The purpose of this study is to find out what hinders potential entrants from entering the market as well as to discuss possible competitive strategies for potential entrants. Our conclusion is that even though the market for transmission of terrestrial digital TV can be viewed as attractive due to its fast growth, there are barriers to entry that block companies we identified as potential entrants from entering the market. The industry experience of the current market players (Teracom and Boxer) along with their knowledge of the consumers and the fact that Teracom is a multi-business company are some of the factors to be taken into consideration. Switching costs is the most important barrier to entry for the industry.

A central question is what view of communication is dominating in a municipality in the southern part of Sweden. The study deals with communication theory from two different perspectives; the view of transmission and the view of creation of meaning. Falkheimer and Heide (2003) claim that the view of transmission is one-way communication where the receivers apprehend passivly. In the view of creation of meaning the goal is to develop and strengthen the common notion that exists in a group. Empirical studies were done, that consisted of qualitative interviews with politicians, directors of the municipality, and principals from three childcare and school areas, and also from one upper secondary school.

AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.

Anledningarna till att använda sig av en trådlös signalöverföring i en industri kan vara många, oftast handlar det om ställen där det är svårt eller omöjligt att ha en trådad förbindelse. I det här fallet är det en sedimenteringsbassäng där man tar hand om processvatten från industrin. Bassängen är utformad som en cylinder där vattnet rinner genom olika avdelningar för att minska innehållet av sediment. I bassängen cirkulerar en plattform med diverse omrörare och skrapor på. Eftersom denna del går runt hela tiden är det svårt att ha en fast förbindelse till de drifter som finns.

This Master's Thesis describes the design of a new system where a digital signal processor has been added to an existing imaging system consisting of field programmable gate arrays. The new system will offer a higher degree of flexibility by considerably shortening the design time and make it possible to implement more complex algorithms than the existing ones. The choice of system architecture and a test implementation are discussed. The test implementation consists of a program for the digital signal processor and VHDL code for one of the field programmable gate arrays. The code for the digital signal processor was designed for testing on an evaluation board from Texas Instruments.

This report explains the need to develop a configuration manager that handles transmission equipment which exists in the Swedish Defence telecommunications network. The configuration module will display the configurations and compatibility among the equipment and their software which are all part of the network.Also included in this report are tools, methods and results for the development of a prototype for the configuration manager. The prototype consists fundamentally of a database assisted by a user friendly website.The transmission equipment handles a lot of important transmission of information and is in the hands of a department of SAAB, OFGCA, by orders from the Swedish Defence Materiel Administration (FMV). Within the work included in this order exists a continuous update of both software and hardware which the equipment consists of. Therefore it?s highly important that there is a monitoring of which of the software and hardware is compatible with one another, ensuring that the functions of the system work properly.The consistent updating has resulted in compatibility issues between components and because of this, a need for a configuration manager has arisen..

This paper describes the work done trying to diminish the noise present in the signal from an IR-detector. The project was aiming towards two different kinds of applications; heat protection and presence detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be installed. After executing the experiments and evaluate the results we recommend to use a specific filter for each application.

Theory has concluded that consumers evaluate advertising not only based on what the advertiser's message aims to communicate, but also how the message is communicated. As the most popular activity on the world's largest social media channels is to upload and share photos, it has become crucial for advertisers to define strategies that maximize the reach of photo posts. Two observed variations of images used in posts are graphical images and digital photographs. The aim of this study is to investigate which of these two strategies that generate most positive impact on the sender and its brand. 230 users of the Chinese Facebook and Twitter counterpart, Sina Weibo, were exposed to manipulated Sina Weibo posts after which they answered a survey.

Stereotypic pacing is frequently observed in captive carnivores, however the underlying causes of this behaviour remain somewhat unclear. One of these possible causes are unpredictable feeding signals, which may give rise to frustration and subsequent pacing. Animal keepers at Nordens Ark had noticed that their Amur leopards had shown stereotypic pacing in connection to the passing of ATVs (All Terrain Vehicles) used by animal keepers primarly when feeding the animals in the park. The aim of this study was to investigate whether the stereotypic pacing of the two Amur leopards at Nordens Ark were affected by the introduction of a signal associated with feeding. The leopards were trained by classical conditioning to associate the sound of a siren with the delivery of food by an animal keeper.

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

In today?s horse keeping, there is an increasing awareness of the importance of movement and activity for the horses comfort and tenability, while tradition has it that horses should be kept in boxes and small paddocks. In order to develop housing systems that fulfils and optimizes the horses needs regarding movement and activity, we need to know more about factors that influence the activity patterns of horses. A first step is to be able to record and analyze the gaits in horses with an automated system. This could be done by use of accelerometer data.In this pilot study, existing accelerometer technique was used to characterize the different gaits in horses (walk, trot and canter) by studying how their respective signal patterns differ and how this is influenced by the size of the horse.The accelerometers being used in this study measures the movement in three different spaces; horizontal, lateral and vertical.

According to science internal communication is a complicated, yet very important, issue of organizations today. An organization with a successful internal communication shows better results both economically and in terms of coworker satisfaction. The two main theories on communication are sensemaking and transmission. After a century with a transmissionary point of view, researchers stress the importance of sensemaking internal communication.Main question of this thesis is ?Which of the two main theories is the most useful when anchoring important messages in large organizations??According to the results of this study, conducted by interviews, neither one is more useful than the other.

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.
