Overview of the scalable video coding extension of the H.264/AVC standard
- IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY IN CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY
, 2007
"... With the introduction of the H.264/AVC video coding standard, significant improvements have recently been demonstrated in video compression capability. The Joint Video Team of the ITU-T VCEG and the ISO/IEC MPEG has now also standardized a Scalable Video Coding (SVC) extension of the H.264/AVC stand ..."

relative to the scalable profiles of prior video coding standards. This paper provides an overview of the basic concepts for extending H.264/AVC towards SVC. Moreover, the basic tools for providing temporal, spatial, and quality scalability are described in detail and experimentally analyzed regarding
Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,
, 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 ..."

of conceptual tools that are directly useful in guiding the implementation and evaluation of work redesign projects. In the paragraphs to follow, we examine several existing theoretical approaches to work redesign, with a special eye toward the measurability of the concepts employed and the action implications
Illusion and well-being: A social psychological perspective on mental health.
- Psychological Bulletin,
, 1988
"... Many prominent theorists have argued that accurate perceptions of the self, the world, and the future are essential for mental health. Yet considerable research evidence suggests that overly positive selfevaluations, exaggerated perceptions of control or mastery, and unrealistic optimism are charac ..."

in normal human cognition (see Fiske& Taylor, 1984; In this article, we review research suggesting that certain illusions may be adaptive for mental health and well-being. In particular, we examine evidence that a set of interrelated positive illusions-namely, unrealistically positive self-evaluations
Toward a Conceptual Framework for Mixed-Method Evaluation Designs. Educational Evaluation and Policy Analysis
, 1989
"... In recent years evaluators of educational and social programs have expanded their method-ological repertoire with designs that include the use of both qualitative and quantitative methods. Such practice, however, needs to be grounded in a theory that can meaningfully guide the design and implementat ..."

and implementation of mixed-method evaluations. In this study, a mixed-method conceptual framework was developed from the theoretical literature and then refined through an analysis of 57 empirical mixed-method evaluations. Five purposes for mixed-method evaluations are identified in this conceptual framework
Power Analysis of Embedded Software: A First Step towards Software Power Minimization
, 1994
"... Embedded computer systems are characterized by the presence ofadedicated processor and the software that runs on it. Power constraints are increasingly becoming the critical component of the design speci cation of these systems. At present, however, power analysis tools can only be applied at the lo ..."

Intelligent Tutoring Goes to School in the Big City
- International Journal of Artificial Intelligence in Education
, 1997
"... Abstract. This paper reports on a large-scale experiment introducing and evaluating intelligent tutoring in an urban High School setting. Critical to the success of this project has been a client-centered design approach that has matched our client's expertise in curricular objectives and class ..."

SUS: A quick and dirty usability scale
, 1996
"... Usability does not exist in any absolute sense; it can only be defined with reference to particular contexts. This, in turn, means that there are no absolute measures of usability, since, if the usability of an artefact is defined by the context in which that artefact is used, measures of usability ..."

Usability and context Usability is not a quality that exists in any real or absolute sense. Perhaps it can be best summed up as being a
Basic Block Distribution Analysis to Find Periodic Behavior and Simulation Points in Applications
, 2001
"... Modern architecture research relies heavily on detailed pipeline simulation. Simulating the full execution of an industry standard benchmark can take weeks to months to complete. To overcome this problem researchers choose a very small portion of a program's execution to evaluate their results, ..."

Visualization of test information to assist fault localization
- In ICSE ’02: Proceedings of the 24th International Conference on Software Engineering
, 2002
"... ABSTRACT One of the most expensive and time-consuming components of the debugging process is locating the errors or faults. To locate faults, developers must identify statements involved in failures and select suspicious statements that might contain faults. This paper presents a new technique that ..."
