QoS Evaluation of BandwidthSchedulers in IPTV Networks OfferedSRD Fluid Video Traffic

Internet protocol TV (IPTV) is predicted to be the key technology winner in the future. Efforts to accelerate the deployment of IPTV centralized model which is combined of VHO, encoders, controller, access network and Home network. Regardless of whether the network is delivering live TV, VOD, or Time-shift TV, all content and network traffic resulting from subscriber requests must traverse the entire network from the super-headend all the way to each subscriber's Set-Top Box (STB).IPTV services require very stringent QoS guarantees When IPTV traffic shares the network resources with other traffic like data and voice, how to ensure their QoS and efficiently utilize the network resources is a key and challenging issue. For QoS measured in the network-centric terms of delay jitter, packet losses and bounds on delay. The main focus of this thesis is on the optimized bandwidth allocation and smooth datatransmission.

Grafisk profilering som en del avvarumärkesarbetet

A strong brand can help a company to be easier to recognize and be remembered by their customers. Part of branding is to create a visual appearance which is called a graphic profile and contains information on for instance a logo, colours or typography.The objective of this thesis was to create a graphic profile for Stjørdal Tannhelsesenter that could serve as a base for a brand work in the future. It was important to analyze how the clinic wants to be perceived and how it is perceived today. The methods used to carry out this study were questionnaires, researches and a focus group.The work resulted in the generation of a graphic profile that included a new logo, colours, decorative elements, fonts, templates for stationery, business card / badge, imagery, and examples of some publications.According to the test which was made to examine the results of the project showed that I was successful and that the new design meets all the requests from the previous questionnaires.

Akademisk kvalitet, vad är det? : Om utarmningen av den akademiska autonomin

What is academic quality? On the decline of academic autonomy In light of the transformations that universities currently undergo, with Bologna as a keyword, the following questions are put: What ideals lie behind the assessment of academic “excellence” and “quality”? What agents have the ability to define what is good science and education today? These questions are approached through Pierre Bourdieus concept of field. Looking at the development the last decade, traditional academic values, such as the ideal of universal knowledge as (personal and collective) enrichment and the intellectual independence “of all political authority and economic power”, as stated in the Magna Charta Universitatum, seem to have emerged into the shadow of employability, knowledge control, competitiveness, and economic benefit. In connection with the formation of concepts such as “the knowledge society” and “knowledge based economies” the university has received a somewhat different and more central role in society. The university has come to take the role more of a knowledge producing enterprise clearly directed towards the surrounding society. There are higher demands on academic knowledge to contribute to economic, regional or national development and competitiveness. When the university is regarded as a knowledge company whose task is to accoun tfor the requests of the students, the labour market, and the business world it undertakes to follow trends and short term social phases rather than to critically examine them, which has been a traditional task for the university. If the academic work is guided by the market economical principle, that the client requests decide what quality is, instead of the experts on the academic field themselves (i.e. the scientists,) it is obviously not scientific ideals that constitute the criteria for what is good science and education.

HR-funktionens förändrade roll : En studie om linjechefers uppfattning av HR-funktionen i Falu och Avesta kommun

Traditionellt har HR-arbetet främst varit fokuserat på administrativa uppgifter och inte ansetts vara tillräckligt effektivt och värdeskapande. För att HR-arbetet ska bli mer strategiskt behöver funktionen organiseras så att den tillgodoser dessa behov (Boglind et al, 2013). Vi menar att HR-funktionens relation till ledare och linjechefer är avgörande för hur framgångsrikt deras arbete blir. Syftet med detta arbete är därför att undersöka hur chefer uppfattar HR-funktionens förändrade roll och vilken typ av stöd de förväntar sig av den. Vi vill också undersöka om uppfattningen av HR-funktionen skiljer sig åt beroende på hur den är organiserad. Undersökningen är baserad på en multipel fallstudie utförd på Falu och Avesta kommun. Totalt har tretton djupintervjuer genomförts, där fem personer representerar HR-avdelningarna och åtta personer representerar linjecheferna. Falu kommun började genomföra en HR-transformation vid årsskiftet 2013/2014, Avesta kommun har inte genomfört en HR-transformation utan har funktionen uppdelad i två team. Av empirin framkommer att linjecheferna i båda kommunerna har en ganska vag uppfattning om HR-funktionens organisation och trots de strukturella skillnaderna mellan kommunerna efterfrågar linjecheferna något mer. I Avesta är samtliga respondenter överens om att en samsyn kring HR-funktionens arbetsuppgifter inte finns på grund av att en tydlig strategi för HR-funktionen saknas. Cheferna i Avesta efterfrågar ett arbete med personalfrågor från grunden samt ett mer strategiskt arbete. I Falun visar empirin att linjechefer och HR-personer har olika åsikter kring huruvida det finns en samsyn. Även om flera linjechefer i Falun anser att HR-funktionen fungerar bättre efter transformationen efterfrågar samtliga en kontakt med en specifik HR-person istället för att kontakta ett HR-center. Trots att de organisationer vi studerat har HR-funktioner som skiljer sig åt i storlek och struktur kan vi konstatera många likheter. Vi drar därför slutsatsen att de problem som linjecheferna beskriver inte är relaterade till HR-avdelningens organisering, utan snarare kan kopplas till en obalans i HR-arbetets inneboende dualitet som uppstått i och med ett mer strategiskt fokus. Vi anser att båda kommunernas HR-funktioner bör ha en tydlig och kontinuerlig dialog med linjecheferna för att maximera värdeskapandet dem emellan. Sammanfattningsvis menar vi att kommunerna bör lägga fokus på att identifiera vilka aspekter av personalarbetet som är värdefulla och unika för just deras organisation samt arbeta strategiskt utifrån dessa.

Upplevelser av stöd från diabetessjuksköterskan hos personer med diabetes typ 1 : – Sekundäranalys av en kvalitativ intervjustudie

Introduction: Type 1 diabetes is a chronic disease that affects the individual in everyday life. The diabetes team sets the treatment goals together with the patient aiming for a good quality of life and to prevent complications. The diabetes nurse should include in-depth knowledge of the daily life of people with diabetes, and have respect for the individual's choices and life situation. Aim: To describe how people with type 1 diabetes experience the support from the diabetes nurse. Method: A qualitative content analysis with an inductive approach has been used. A secondary analysis including semi-structured interviews with 15 adults (> 18 years) with type 1 diabetes was conducted. Result: The result was summarized with an overall theme "At the clinic - experience of the support offered" describes how people experience the support from their diabetes nurse. The theme constituted three categories "Access to the diabetes nurse", "The diabetes nurse - a source of information and knowledge that might need to be complemented with the support from other professionals" and,"Mutual trust - the patient's experience of the district nurse as a discussion partner and support". Conclusion: The results showed that the accessibility to diabetes nurses was experienced as good. It was simple and easy to make contact. The diabetes nurses were experienced to be engaged and provide good support to the patients. A good dialogue with the diabetes nurse and commitment from the diabetes nurse were mentioned as important factors that made the visits to be experienced as good and important. There were requests for greater access and expanded opportunities for help from counselors, as well as an increased focus on how the person is feeling.
