Reliable and fast sensing of the environment is a fundamental requirement for autonomous mobile robotic platforms. Unfortunately, the frame-based acquisition paradigm at the basis of main stream artificial perceptive systems is limited by low temporal dynamics and redundant data flow, leading to high computational costs. Hence, conventional sensing and relative computation are obviously incompa...

A review of market trends impacting the development of the applications architecture of the Internet in general is presented, followed by an historical review of the subject and an analysis of regulatory aspects. It concludes with a review of the state of backbone interconnection in Latin America. r 2005 Elsevier Ltd. All rights reserved.

The Transversal Hypergraph Generation is the problem of generating, given a hypergraph, the set of its minimal transversals, i.e., the hypergraph whose hyperedges are the minimal hitting sets of the given one. The purpose of this paper is to present an efficient and practical algorithm for solving this problem. We show that the proposed algorithm operates in a way that rules out regeneration an...

SPONSORS: FFM is jointly sponsored by the Intelligence Systems Support Office (ISSO) of OASD/C3I, the National Drug Intelligence Center (NDIC) and the Office of Research and Development (ORD). The prototype is being built and evaluated at the Federal Intelligent Document Understanding Laboratory (FIDUL) in Tyson's Comers, VA, in an unclassified environment which replicates the hardware and soft...

Since the landmark introduction of an ethnic group question to the 1991 Census (Bulmer, 1996) and the influential Fourth National Survey of Ethnic Minorities in 1993-4 (Modood et al., 1997), the volume of social research addressing ethnicity has grown dramatically in the UK. Social researchers are increasingly required to produce evidence capable of informing policy and practice development tha...

economists were interested in economic stabilization policies as early as the 1930’s but the formal applications of stability theory from the classical control theory to economic analysis appeared in the early 1950’s when a number of control engineers actively collaborated with economists on economic stability and feedback mechanisms. the theory of optimal control resulting from the contributio...

the increasing diversity in packet-processing applications together with the rapid increase in channel bandwidth has brought about greater complexity in communication protocols. also influenced by these factors is the computational load for packet-processing engines, demanding high performance microprocessor designs as an indispensable solution. this paper reports on extensive simulation experi...

Models inferred from system execution logs can be used to test general system behaviour. In this paper, we infer test models from user bug reports that are written in the natural language. The inferred models can be used to derive new tests which further exercise the buggy features reported by users. Our search-based model inference approach considers three objectives: (1) to reduce the number ...

ARCHITECTING PROTOCOLS TO ENABLE MOBILE APPLICATIONS IN DIVERSE WIRELESS NETWORKS

Desire2Move (D2M) was an 8-week team based program designed to encourage physical activity among university employees. The purpose of this study was to conduct a RE-AIM evaluation of the program. Eligible participants were university employees and tracked daily physical activity minutes using a mobile app or a pedometer and total team minutes were calculated. Ten weeks after D2M, an online surv...
