1. 1. Improving user comprehension and entertainment in wireless streaming media : introducing cognitive quality of service

   Författare :Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multicast channels; Quality of Service; Cognitive QoS; Wireless LAN; Multiaccess Communication; IEEE 802.11; Displays; Mobile Communications; Video Coding; Tracking; Animation; Cognitive Psychology; Experience Design; Computer science; Datavetenskap;

   Sammanfattning : In future mobile networks service quality might be poor. A new measure is needed to be able to assess services in terms of their effectiveness and usefulness despite their lacking visual appeal. Cognitive Quality of Service is a way to measure the effectiveness in use of a networked service. LÄS MER

3. 2. Aspects of Quality : Using Quality Measurements to Improve Computer Network Performance

   Författare :Pehr Söderman; Peter Sjödin; Markus Hidell; Karl-Johan Grinnemo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; Datalogi;

   Sammanfattning : As computer networks grow in complexity, measuring the performance becomes a challenge. Intrinsic properties of the networks capability to transport data, such as bandwidth, latency, loss, and error rate are not always enough to provide a clear picture of how well the network can satisfy the users' expectations.

4. 3. Quality of Experience on Smartphones : Network, Application, and Energy Perspectives

   Författare :Selim Ickin; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; QoE; QoS; Energy; Mobile computing;

   Sammanfattning : Smartphones have become crucial enablers for users to exploit online services such as learning, leisure, communicating, and socializing. The user-perceived quality of applications and services is an important factor to consider, in order to achieve lean resource management, to prevent user churn and revenue depletion of service or network providers.

5. 4. Modeling and Tuning Security from a Quality of Service Perspective

   Författare :Stefan Lindskog; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; network security; quality of service QoS ; tunable security; dependability; security service; data protection; security evaluation; Datavetenskap; Computer Science;

   Sammanfattning : Security has traditionally been thought of as a system or network attribute that was the result of the joint endeavors of the designer, maintainer and user, among others. Even though security can never reach a level of 100%, the aim has been to provide as much security as possible, given the boundary conditions in question. With the advent of, e.g. LÄS MER

7. 5. Formal Approaches for Behavioral Modeling and Analysis of Design-time Services and Service Negotiations

   Författare :Aida Čaušević; Paul Pettersson; Cristina Seceleanu; Ina Schieferdecker; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Service-Oriented Systems; Formal modeling and Analysis; Service; Service Composition; Service Negotiation; Computer Science; datavetenskap;

   Sammanfattning : During the past decade service-orientation has become a popular design paradigm, offering an approach in which services are the functional building blocks. Services are self-contained units of composition, built to be invoked, composed, and destroyed on (user) demand. LÄS MER
