Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.
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.
Funktioner i företags data mining-verktyg
I denna uppsats undersöks vilka funktioner som är implementerade i organisationers data mining-verktyg. De funktioner som undersöks, är identifierade i litteraturstudier om data mining och datalager. I uppsatsen beskrivs vad ett datalager är, samt mer ingående vad data mining innebär. Fallstudien har skett genom kvalitativa djupintervjuer med respondenter från fyra olika organisationer, där respondenterna arbetar som expertanvändare av data mining-verktygen. Slutsatsen i denna uppsats är att organisationernas data mining-verktygen inte har alla funktioner, som identifierats, implementerade och att funktionerna skiljer sig mycket mellan organisationernas data mining-verktyg..
Varumärkesvärde ur två perspektiv : En gap-analys av försäkringsbranschen
Aim: The purpose of this study is to examine and analyze how insurance companies work to create value and confidence in their brands and then compare whether consumers perceive brands as companies seek.Method: The study is a gap analysis of both qualitative and quantitative in nature containing both interviews with insurance companies and a survey carried out on consumers. The study has been developed by analytical induction.Data: Consists of interviews with representatives from the insurance companies and survey responses from 99 consumers.Conclusion: From the study it can be concluded that the insurance industry is unique in its kind as a difficulty and complexity is obviously applicable to convey an overall impression to the consumer, which in turn will produce a brand value to the company. Creating a high brand value through good marketing where it maintained a good congruence between firms striving and consumer perception, is according to the scientists complicated because the lack of perceived quality affects the the big picture..
Stopptids- och avvikelseuppfo?ljning vid la?nga takttider : Fra?n avvikelse till info?rd fo?rba?ttring
High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.
Implikationer av tjänsteföretagets utfästelser för kunders reaktioner i felsituationen
The characteristic of services as an effort carried out in a "moment of truth" implies a risk for failures. This study sheds new light on how alternative offerings that customers are initially exposed to can affect satisfaction and loyalty in the service failure and recovery context. More specifically, two aspects of the initial offering are studied: promised general service quality and the presence of a promise about a specific product attribute. Based on a presentation of the main theoretical perspectives, hypotheses are formulated and a scenario-based experiment in a hotel setting is designed to explore these. The results indicate that a higher level of promised service quality can result in more positive evaluations of satisfaction and stronger word-of-mouth intentions than for a lower level of promised service quality.
Den som gapar efter mycket, fångar ofta hela stycket - En kvantitativ studie om konsumenters emotionella band till varumärken
This paper examines the relationship between the experienced quality in the offering of a brand, emotional attachment and consumer commitment. The study aim to explore several dimensions of the experienced quality in the offering of a brand. Further we examine two conceptualizations of emotional attachment - Brand Attachment and Brand Love - and intend to declare the two of being two separate phenomena. We then conduct a relationship-based analysis wherein the mediating ability of Brand Attachment and Brand Love, between the experienced quality in the offering of a brand and consumer commitment, is examined. Therefore we conduct a focused quantitative study, wherein 171 customers of the fashion retailer H&M have responded to a comprehensive survey both online and in-store, to examine this fun-damental relationship and its components.
Ip-telefoni med Skype som ett alternativ till PSTN för privatanvändare
The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security.
