The Message Handler extracts critical intelligence information from the free-text of military messages to merge with the data'parsed from fixed-fields. In the third of four project phases, the current focus is on developing stand-alone capabilities demonstrating the viability of natural language processing in Advance Concept Technology Demonstrations (ACTDs), and to operational users at militar...

In this paper we address the task of human-robot interaction in public mass exposition with several autonomous robots at a time. This implies questions regarding multi-robot control and interaction management with respect to social and commercial aspects of such an exposition. Multi-robot and interaction management is addressed with respect to visitor density and visitor flow. Human-robot inter...

We propose a new probabilistic ant-based heuristic (ANTH-LS) for the longest simple cycle problem. This NP-hard problem has numerous real-world applications in complex networks, including efficient construction of graph layouts, analysis of social networks or bioinformatics. Our algorithm is based on reinforcing the probability of traversing the edges, which have not been present in the long cy...

We show that there is a close connection between the construction of the perfect kernel of a Π1 class via the interation of the Cantor-Bendixson derivative through the ordinals and the construction of the well-founded semantics for logic programs via Van Gelder’s alternating fixpoint construction. This connection allows us to transfer known complexity results for the perfect kernel of Π1 classe...

Multimedia information retrieval poses both technical and design challenges beyond those of established text retrieval. These issues extend both to the entry of search requests, system interation and the browsing of retrieved content, and the methodologies and techniques for content indexing. Prototype multimedia information retrieval systems are currently being developed which enable the explo...

This paper treats interaction between finitely many particles where the future state of each particle is obtained from the present states of all other particles by a positive linear combination with time variant coefficients. The main result provides conditions for a common globally asymptotically stable equilibrium to exist. These conditions are, in particular, satisfied if the particles show ...

In this paper, we show that the estimated intra-cranial sources using source localization on EEG signals can be used for online Brain Computer Interation (BCI) and the discriminant sources remain stable over days. Classifiers are trained on discriminant sources obtained for Error-related Potential (ErrP) based BCI on day 1 and then tested online on day 2. The results for nine subjects show that...

In this work, we present a new three-dimensional Monte Carlo (MC) method which naturally recovers the realspace carrier-impurity Coulomb interaction by mesh-based resolution of Poisson’s equation. This method necessitates no additional modifications to the conventional MC simulator, thus simplifying the implementation process. The new method has been validated through the reproduction of the do...

The bubble electrospinningis a peerless technology for mass-production of various functional nanofibers. During the spinning process, multiple jets are ejected, which might be interacted with each other. interaction result in mass transfer, energy transfer and force balance, all these factors will greatly affect mechanical property morphology resultant fibers. A theoretical model is established...
