On the Private Provision of Public Goods
by Theodore Bergstrom, Lawrence Blume, Hal Varian - Journal of Public Economics , 1986
"... We consider a general model of the non-cooperative provision of a public good. Under very weak assumptions there will always exist a unique Nash equilibrium in our model. A small redistribution of wealth among the contributing consumers will not change the equilibrium amount of the public good. Howe ..."

A Survey of Computer Vision-Based Human Motion Capture
by Thomas B. Moeslund, Erik Granum - Computer Vision and Image Understanding , 2001
"... A comprehensive survey of computer vision-based human motion capture literature from the past two decades is presented. The focus is on a general overview based on a taxonomy of system functionalities, broken down into four processes: initialization, tracking, pose estimation, and recognition. Each ..."

Knowledge and Common Knowledge in a Distributed Environment
by Joseph Y. Halpern, Yoram Moses - Journal of the ACM , 1984
"... : Reasoning about knowledge seems to play a fundamental role in distributed systems. Indeed, such reasoning is a central part of the informal intuitive arguments used in the design of distributed protocols. Communication in a distributed system can be viewed as the act of transforming the system&apo ..."
's state of knowledge. This paper presents a general framework for formalizing and reasoning about knowledge in distributed systems. We argue that states of knowledge of groups of processors are useful concepts for the design and analysis of distributed protocols. In particular, distributed knowledge

The results show that common-law countries generally have the strongest, and French-civil-law countries the weakest, legal pr ..."

Risk and protective factors for alcohol and other drug problems in adolescence and early adulthood: Implications for substance abuse prevention
by J. David Hawkins, Richard E Catalano, Janet Y Miller - Psychological Bulletin , 1992
"... The authors suggest that the most promising route to effective strategies for the prevention of adolescent alcohol and other drug problems is through a risk-focused approach. This approach requires the identification of risk factors for drug abuse, identification of methods by which risk factors hav ..."
, and make recommendations for research and practice. In spite of general decreases in the prevalence of the nonmed-ical use of most legal and illegal drugs in recent years, the abuse of alcohol and other drugs during adolescence and early adulthood remains a serious public health problem (Adams, Blanken
Establishing Pairwise Keys in Distributed Sensor Networks
by Donggang Liu, Peng Ning , 2003
"... Pairwise key establishment is a fundamental security service in sensor networks; it enables sensor nodes to communicate securely with each other using cryptographic techniques. However, due to the resource constraints on sensors, it is infeasible to use traditional key management techniques such as ..."
such as public key cryptography and key distribution center (KDC). To facilitate the study of novel pairwise key predistribution techniques, this paper presents a general framework for establishing pairwise keys between sensors on the basis of a polynomial-based key predistribution protocol [2].

Protecting respondents' identities in microdata release
by Pierangela Samarati - In IEEE Transactions on Knowledge and Data Engineering (TKDE , 2001
"... Today's globally networked society places great demand on the dissemination and sharing of information. While in the past released information was mostly in tabular and statistical form, many situations call today for the release of specific data (microdata). In order to protect the anonymity of the ..."

Fully homomorphic encryption using ideal lattices
by Craig Gentry - In Proc. STOC , 2009
"... We propose a fully homomorphic encryption scheme – i.e., a scheme that allows one to evaluate circuits over encrypted data without being able to decrypt. Our solution comes in three steps. First, we provide a general result – that, to construct an encryption scheme that permits evaluation of arbitra ..."

Fuzzy extractors: How to generate strong keys from biometrics and other noisy data
by Yevgeniy Dodis, Rafail Ostrovsky, Leonid Reyzin, Adam Smith , 2008
"... We provide formal definitions and efficient secure techniques for • turning noisy information into keys usable for any cryptographic application, and, in particular, • reliably and securely authenticating biometric data. Our techniques apply not just to biometric information, but to any keying mater ..."
if the input changes, as long as it remains reasonably close to the original. Thus, R can be used as a key in a cryptographic application. A secure sketch produces public information about its input w that does not reveal w, and yet allows exact recovery of w given another value that is close to w. Thus
