Receiver-driven Layered Multicast

by Steven McCanne, Van Jacobson, Martin Vetterli , 1996
"... State of the art, real-time, rate-adaptive, multimedia applications adjust their transmission rate to match the available network capacity. Unfortunately, this source-based rate-adaptation performs poorly in a heterogeneous multicast environment because there is no single target rate — the conflicti ..."

STATEMATE: A Working Environment for the Development of Complex Reactive Systems

by David Harel, Hagi Lachover, Amnon Naamad, Amir Pnueli, Michal Politi, Rivi Sherman, Aharon Shtull-trauring, Mark Trakhtenbrot - IEEE Transactions on Software Engineering , 1990
"... This paper provides an overview of the STATEMATE system, constructed over the past several years by the authors and their colleagues at Ad Cad Ltd., the R&D subsidiary of i-Logix, Inc. STATEMATE is a set of tools, with a heavy graphical orientation, in- tended for the specification, analysis, d ..."

It enables a user to prepare, analyze, and debug diagram- matic, yet precise, descriptions of the system under development from

Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,

by ] Richard Hackman , Grec R Oldham , 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

with before the theory can be fully applied to real-world job design problems. First, means must be developed for measuring current levels of activation of individuals in actual work settings (cf. Thayer, 1967), and for assessing the "optimal level" of activation for different individuals. Until

The minimum description length principle in coding and modeling

by Andrew Barron, Jorma Rissanen, Bin Yu - IEEE TRANS. INFORM. THEORY , 1998
"... We review the principles of Minimum Description Length and Stochastic Complexity as used in data compression and statistical modeling. Stochastic complexity is formulated as the solution to optimum universal coding problems extending Shannon’s basic source coding theorem. The normalized maximized ..."

likelihood, mixture, and predictive codings are each shown to achieve the stochastic complexity to within asymptotically vanishing terms. We assess the performance of the minimum description length criterion both from the vantage point of quality of data compression and accuracy of statistical inference

Videoconferencing on the Internet

by Thierry Turletti, Christian Huitema - IEEE/ACM Trans. on Networking , 1996
"... This paper describes the INRIA Videoconferencing System (IVS), a low bandwidth tool for real-time video between workstations on the Internet using UDP datagrams and the IP multicast extension. The video coder-decoder (codec) is a software implementation of the UIT-T recommendation H.261 originally d ..."

Data privacy through optimal k-anonymization

by Roberto J. Bayardo - In ICDE , 2005
"... Data de-identification reconciles the demand for release of data for research purposes and the demand for privacy from individuals. This paper proposes and evaluates an optimization algorithm for the powerful de-identification procedure known as k-anonymization. A k-anonymized dataset has the proper ..."

Image information and visual quality

by Hamid Rahim Sheikh, Alan C. Bovik - IEEE Trans. IP , 2006
"... Abstract—Measurement of visual quality is of fundamental importance to numerous image and video processing applica-tions. The goal of quality assessment (QA) research is to design algorithms that can automatically assess the quality of images or videos in a perceptually consistent manner. Image QA a ..."

Developments in the Measurement of Subjective Well-Being

by Daniel Kahneman , Alan B Krueger - Psychological Science. , 1993
"... F or good reasons, economists have had a long-standing preference for studying peoples' revealed preferences; that is, looking at individuals' actual choices and decisions rather than their stated intentions or subjective reports of likes and dislikes. Yet people often make choices that b ..."

, are required to undergo an experience, such as being exposed to loud noises or watching a film clip. They are asked to provide a continuous indication of the hedonic quality of their experience in real time by manipulating a lever that controls a marker on a scale, which is usually defined by extreme values

Behavior Coding Assessment of the Quality of Real-time Telephone Survey Interpreters

by Michael W. Link, Larry Osborn, Marta Induni, Michael P. Battaglia, Martin R. Frankel
"... Real-time interpretation during a survey can expand the number of languages in which surveys are offered. There are questions, however, about the quality of the interpretation process given that the interview is typically not pre-translated. A detailed assessment of the quality of this approach is p ..."

Real-time monitoring of video quality in IP networks

by Shu Tao - In Proceedings of NOSSDAV , 2005
"... This paper investigates the problem of assessing the quality of video transmitted over IP networks. Our goal is to develop a methodology that is both reasonably accurate and simple enough to support the large-scale deployments that the increasing use of video over IP are likely to demand. For that p ..."

on many parameters that are difficult to estimate in real-time. As a result, we introduce a “relative quality” metric that bypasses this problem by measuring video quality against a quality benchmark that the network is expected to provide. The approach offers a lightweight video quality monitoring
