Ternary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. Regardless whether the fluctuations of the channel are intentional or not the idea is to let the coderate decrease so that the error correcting capability can increase for the part of the information to be more protected. By using the support, the nonzero positions of the ternary code, a new binary code can be extracted with properties different from the ternary code in the sense of cardinality and minimum Hamming distance. When the channel conditions are good the receiver decodes the message using ternary decisions and receives all information included in the codeword.

Målet med detta arbete har varit att besvara frågan; ?Varför uppstår det så mycket problem med trådlösa nätverk??.

This study is on how small companies can use the Internet as a part of their marketing strategy to gain a leverage on their competitors with small means to survive and expand in the global market. Many Swedish small companies still don?t have a sufficient knowledge on how to use the communication channel despite the various advantages the Internet offers.Case studies were conducted of how AdLibris, A-lotterierna AB and SF-bokhandeln perceived the importance of using the Internet as a part of their communications strategy.This new communication channel demand new ways of applying traditional marketing principals. Careful analysis of the interviews and how the answers relate to new and old marketing theories makes the bulk of this study. The conclusion is that the Internet solely is not enough, a combination with traditional marketing tools is the way to succeed in their marketing efforts.

This is a case study of the music channel MTV and it?s impact on the Swedish mediascape. We want to look into the process that lies behind this huge intercontinental corporation. Through literature studies we present the mechanism?s that paved the way for MTV growing into the number one music channel of modern time.

Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.

Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

Customer service has traditionally consisted of telephone, mail, and later on chat.But the entry of social media has changed the way companies exercise customerservice. Companies should ask themselves whether the same type of traditionalcommunication may or may not function in a new channel and thus whether itcan be applied to social media.The purpose of this study is to describe the companies? use of customer servicein social media and how the communication differentiates from thecommunication in traditional customer service, and also to define the effect onthe customers? relationship to the company. To reach our conclusions we havecombined theoretical references with qualitative interviews.By our analysis, we found that the communication in social media expandsthe possibilities. By entering an unfamiliar channel, customer service has hadto adapt themselves and their language.

Introduction: As the media landscape has changed so has fierce competition in the market, giving an effect of stronger commercialization of the media. Societal problems in our society are caused by increased commercialization and market orientation. Media has gone from trusted social institutions to focus on their own economic interests, where owners are expected revenue. The content of the media is characterized more and more by entertainment, because it attracts a larger audience. On one side media is expected to contribute to democracy in society and on the other they are expected to contribute profits to their owners, which creates a conflict in today?s media society.

The high and seemingly increasing degree of consumer avoidance and disliking of television advertising breaks should raise many questions for commercially financed television networks as it can be argued that benefits sought by both viewers [seeking a fulfilling viewing experience] and advertisers [seeking advertising effectiveness] are eroded by this effect. This thesis studies effects on advertising effectiveness [RecallBRAND; AttitudeBRAND; AttitudeAD] as well as on the viewing experience [SatisfactionPROGRAM/CHANNEL; Attitude PROGRAM/CHANNEL; IntentionPROGRAM/CHANNEL] given a reduced degree of advertising clutter. By conducting an experiment two breaks are compared, one having the standard primetime nonprogram time units (5 min and 30 sec *3?16minutes/hour) and the other the standard nonprogram content cut in half (2.45 min *3 ?8min /hour).Results show that the reduced breaks award advertisers with higher commercial effectiveness. Measures of RecallBRAND demonstrates no differences between the standard and the reduced break, implying a significantly increased likelihood to be recalled and an equivalently lowered risk to be forgotten in the reduced break.

The technological development and increasing popularity for integrated multichannel solutions constitutes both severe opportunities and challenges for todays' and tomorrows' retailers. On the account of consumers leaving traces when using digital channels and the technological development enabling retailers to use this information to create relevant offers, goal-congruity is relevant to apply in the multichannel shopping context. Based upon previous research on goal congruity and channel integration, our main purpose in this study is to increase the understanding for how congruity in an offer increases the intention to redeem the offer. Several studies focus on and contrast the product characteristics hedonic and utilitarian. However, it has been stated that it is crucial that research also examines the difference in target audience, buying situation and as examined in this study: buying decision process.
