For a set F of connected graphs, a graph G is said to be F-free if G does not contain any member of F as an induced subgraph. The members of F are referred to as forbidden subgraphs. When we study the relationship between forbidden subgraphs and a certain graph property, we often allow the existence of exceptional graphs as long as their number is finite. However, in this type of research, if t...

The motor cortex was the one of the first cortical areas to be explored electrophysiologically, yet little agreement has emerged regarding its basic response properties. Often it is assumed that single-neuron responses reflect a preference for a particular movement or movement variable. It may be further assumed that movement is generated by (or at least accompanied by) a growing population-lev...

This paper discusses an approach to generate headline summary from a set of documents. Headline summary is basically a very short summary in the form of headline. As the amount of on-line information increases, systems that can automatically summarize multiple documents are becoming increasingly desirable. In this situation, headline summary is useful for users who only need information on the ...

This little draft paper describes some first ideas to extend the theoretical concepts of WSMF (and WSMO) to Grid service approach. WSMF is a framework for Semantic Web Services and WSMO is the corresponding ontology. Advances in Web/Grid services have been detailed in the WSRF specification. This draft paper proposes firstly a framework as an extension of WSMF, and secondly details modification...

An overview is presented of the recent developments in the application of large eddy simulation (LES) for prediction and analysis of local entropy generation in turbulent reacting flows. A challenging issue in such LES is subgrid-scale (SGS) modeling of filtered entropy generation terms. An effective closure strategy, recently developed, is based on the filtered density function (FDF) methodolo...

Streaming variational Bayes (SVB) is successful in learning LDA models in an online manner. However previous attempts toward developing online Monte-Carlo methods for LDA have little success, often by having much worse perplexity than their batch counterparts. We present a streaming Gibbs sampling (SGS) method, an online extension of the collapsed Gibbs sampling (CGS). Our empirical study shows...

Here hi = uiφ − ūiφ̄ is the SGS scalar flux. Both τij and hi are not available from the resolved (LES) flow field and thus have to be modeled. A very promising approach to modeling τij and hi consists of utilization of extra LES quantities such as SGS kinetic energy (Schumann 1975; Ghosal et al. 1995) and SGS scalar variance (Jiménez et al. 2001; Chumakov & Rutland 2004, 2005). For these quantit...

HPIV measurements of a turbulent flow in a square duct are used for studying the 3-D geometric relations between SGS stresses, filtered strain-rates and vorticity. Conditional sampling is performed based on the strain-rate magnitude and SGS dissipation, including negative values. In regions of high dissipation, the flow is more likely to be in axisymmetric expansion with vorticity strongly alig...

The computational difficulties occurred when we use a conventional support vector machine with nonlinear kernels to deal with massive datasets. The reduced support vector machine (RSVM) replaces the fully dense square kernel matrix with a small rectangular kernel matrix which is used in the nonlinear SVM formulation to avoid the computational difficulties. In this paper, we propose a new algori...

An Analog Memory suitable to storage a fotogenerated image frame is described. An architecture that allows a fast writing rate is presented. The Memory has a serial input and eight channels parallel output; it can store a QCIF image (176x144 pixels) for 1/15 sec with an equivalent precision of 7bit. Nominal input writing frequency is 2,5MHz and output reading frequency is 0,833MHz. The CHIP nee...
