Comprehensive database for facial expression analysis

by Takeo Kanade, Jeffrey F. Cohn, Yingli Tian - in Proceedings of Fourth IEEE International Conference on Automatic Face and Gesture Recognition
"... Within the past decade, significant effort has occurred in developing methods of facial expression analysis. Because most investigators have used relatively limited data sets, the generalizability of these various methods remains unknown. We describe the problem space for facial expression analysis, ..."

Xen and the art of virtualization

by Paul Barham, Boris Dragovic, Keir Fraser, Steven Hand, Tim Harris, Alex Ho, Rolf Neugebauer, Ian Pratt, Andrew Warfield - IN SOSP , 2003
"... Numerous systems have been designed which use virtualization to subdivide the ample resources of a modern computer. Some require specialized hardware, or cannot support commodity operating systems. Some target 100 % binary compatibility at the expense of performance. Others sacrifice security or fun ..."

or functionality for speed. Few offer resource isolation or performance guarantees; most provide only best-effort provisioning, risking denial of service. This paper presents Xen, an x86 virtual machine monitor which allows multiple commodity operating systems to share conventional hardware in a safe and resource

RSVP: A New Resource Reservation Protocol

by Lixia Zhang, Stephen Deering, Deborah Estrin, Scott Shenker, et al. , 1993
"... Whe origin of the RSVP protocol can be traced back to 1991, when a team of network researchers, including myself, started playing with a number of packet scheduling algorithms on the DARTNET (DARPA Testbed NETwork), a network testbed made of open source, workstation-based routers. Because scheduling ..."
Abstract - Cited by 1005 (25 self) - Add to MetaCart
scheduling algorithms simply shuffle packet processing orders according to some established rates or priorities for different data flows, to test a scheduling algorithm requires setting up the appropriate control state at each router along the data flow paths. I was challenged to design a set-up protocol

What good are positive emotions

by Barbara L. Fredrickson - Review of General Psychology , 1998
"... This article opens by noting that positive emotions do not fit existing models of emotions. Consequently, a new model is advanced to describe the form and function of a subset of positive emotions, including joy, interest, contentment, and love. This new model posits that these positive emotions ser ..."

Any review of the psychologi- ideas presented here, but also to build other new cal literature on emotions will show that models that might illuminate the nature and psychologists have typically favored negative value of positive emotions.

Labeled Faces in the Wild: A Database for Studying Face Recognition in Unconstrained Environments

by Gary B. Huang, Manu Ramesh, Tamara Berg, Erik Learned-Miller
"... Face recognition has benefitted greatly from the many databases that have been produced to study it. Most of these databases have been created under controlled conditions to facilitate the study of specific parameters on the face recognition problem. These parameters include such variables as posi ..."

over such parameters. This database is provided as an aid in studying the latter, unconstrained, face recognition problem. The database represents an initial attempt to provide a set of labeled face photographs spanning the range of conditions typically encountered by people in their everyday lives

The Linear Time-Branching Time Spectrum II - The semantics of sequential systems with silent moves

by R.J. van Glabbeek , 1993
"... ion Rule (KFAR) (Baeten, Bergstra & Klop [3]), expresses a global fairness assumption. It says that when possible a system will escape from any cycle of internal actions. Some form of KFAR is crucial for many protocal verifications with unreliable channels, and for that reason preorders and equi ..."

A hierarchical model of approach and avoidance achievement motivation

by Andrew J. Elliot, Marcy A. Church - Journal of Personality and Social Psychology , 1997
"... A hierarchical model of approach and avoidance achievement motivation was proposed and tested in a college classroom. Mastery, performance-approach, and performance-avoidance goals were assessed and their antecedents and consequences examined. Results indicated that mastery goals were grounded in ac ..."

A Survey of Affect Recognition Methods: Audio, Visual, and Spontaneous Expressions

by Zhihong Zeng, Maja Pantic, Glenn I. Roisman, Thomas S. Huang , 2009
"... Automated analysis of human affective behavior has attracted increasing attention from researchers in psychology, computer science, linguistics, neuroscience, and related disciplines. However, the existing methods typically handle only deliberately displayed and exaggerated expressions of prototypi ..."

of prototypical emotions, despite the fact that deliberate behavior differs in visual appearance, audio profile, and timing from spontaneously occurring behavior. To address this problem, efforts to develop algorithms that can process naturally occurring human affective behavior have recently emerged. Moreover

Finding bugs is easy

by David Hovemeyer, William Pugh - ACM SIGPLAN Notices , 2004
"... Many techniques have been developed over the years to automatically find bugs in software. Often, these techniques rely on formal methods and sophisticated program analysis. While these techniques are valuable, they can be difficult to apply, and they aren’t always effective in finding real bugs. Bu ..."

that the effort required to implement a bug pattern detector tends to be low, and that even extremely simple detectors find bugs in real applications. From our experience applying bug pattern detectors to real programs, we have drawn several interesting conclusions. First, we have found that even well tested code

Pragmatics of measuring recognition memory: Applications to dementia and amnesia.

by Joan Gay Snodgrass , June Corwin - Journal of Experimental Psychology: General, , 1988
"... SUMMARY This article has two purposes. The first is to describe four theoretical models of yesno recognition memory and present their associated measures of discrimination and response bias. These models are then applied to a set of data from normal subjects to determine which pairs of discriminati ..."
