criterion that uses the eigenvalues of the graph Laplacian matrix to determine the effect of the graph on formation stability. We also propose a method for decentralized information exchange between vehicles. This approach realizes a dynamical system that supplies each vehicle with a common reference

The use of hierarchy is an important component of object-oriented design. Hierarchy allows the use of type families, in which higher level supertypes capture the behavior that all of their subtypes have in common. For this methodology to be effective, it is necessary to have a clear understanding

assumptions about the form of the solution. We define detection and localization criteria for a class of edges, and present mathematical forms for these criteria as functionals on the operator impulse response. A third criterion is then added to ensure that the detector has only one response to- a single edge

whether or not the theory or hypothesis fits one's intuition or one's common sense. In this meaning much of the theory which is to be presented here is not" plausible ". The theory does, however, explain a considerable amount of data and leads to testable derivations. Three experiments

of the selection of substitution models in phylogenetics from a theoretical, philosophical and practical point of view, and summarize this comparison in table format. We argue that the most commonly implemented model selection approach, the hierarchical likelihood ratio test, is not the optimal strategy for model

This paper is a theoretical dissertation on the role of the matter and its representations through dynamics in the organization of the multisensory space. We assume that the mechanical matter, which originally produces the multisensory-handled events, is an invariant identified from the spatio-temporal correlation between visual, auditory and tactilo-proprio-kinesthetic perceptions. We illustrate this assumption by several examples using virtual objects modeled by means of physically-based formalism, able to produce dynamically plausible and consistent multisensory events. We then examine frontiers between ambiguous notions as: geometry vs. dynamics in visual believability, optical matter vs. mechanical matter in contour identification, interaction vs. morphology or topology vs. force in complex manipulations. We conclude that, a challenge to enhance the presence of virtual objects is to be able to instill in their models a just sufficient clue of evoked materiality using minimal physically-based representations.

investigation of the feasibility of conducting validity studies of the GRE using a common criterion task. It was determined that such a study was not feasible. However some committee members suggested that many graduate departments used some type of ratings of graduate students; that rating scale

We present a method for object categorization in real-world scenes. Following a common consensus in the field, we do not assume that a figure-ground segmentation is available prior to recognition. However, in contrast to most standard approaches for object class recognition, our approach

bias measure analogous to C. Cis defined as the distance of criterion from the intersection of the two underlying distributions. The second purpose is to use the indices from the acceptable models to characterize recognition memory deficits in dementia and amnesia, \bung normal subjects, Alzheimer

This paper addresses the joint design of transmit and receive beamforming or linear processing (commonly termed linear precoding at the transmitter and equalization at the receiver) for multicarrier multiple-input multiple-output (MIMO) channels under a variety of design criteria. Instead
