We report on recent work to determine the CKM matrix element |Vus| using strange hadronic τ decay data. We use the recent OPAL update of the strange spectral function, while on the theory side we update the dimension-two perturbative contribution including the recently calculated α 3 s terms. Our result |Vus| = 0.2220±0.0033 is already competitive with the standard extraction from Ke3 decays an...

Vanishing point locations play a critical role in determining the perspective orientation of textured planes. However, if only a single vanishing point is available then the problem is undetermined. The tilt direction must be computed using supplementary information such as the texture gradient. In this paper we describe a method for multiple vanishing point and, hence complete perspective pose...

BACKGROUND The discrete Fourier transform (DFT) is often used as a spectral estimator for analysis of complex fractionated atrial electrograms (CFAE) acquired during atrial fibrillation (AF). However, time resolution can be unsatisfactory, as the frequency resolution is proportional to rate/time interval. In this study we compared the DFT to a new spectral estimator with improved time-frequency...

We show how to exploit enzymatic saturation -an ubiquitous nonlinear effects in biochemistryin order to process information in molecular networks. The networks rely on the linearity of DNA strand displacement and the nonlinearity of enzymatic replication. We propose a pattern-recognition network that is compact and should be robust to leakage.

The high dimensionality of the data generated by social networks has been a big challenge for researchers. In order to solve the problems associated with this phenomenon, a number of methods and techniques were developed. Spectral clustering is a data mining method used in many applications; in this paper we used this method to find students’ behavioral patterns performed in an elearning system...

We have seen that there is a one-to-one relationship between the direction of a signal and the associated received steering vector. It should therefore be possible to invert the relationship and estimate the direction of a signal from the received signals. An antenna array therefore should be able to provide for direction of arrival estimation. We have also seen that there is a Fourier relation...

This article addresses the problem of twoand higher dimensional pattern matching, i.e. the identification of instances of a template within a larger signal space, which is a form of registration. Unlike traditional correlation, we aim at obtaining more selective matchings by considering more strict comparisons of gray-level intensity. In order to achieve fast matching, a nonlinear thresholded v...

In this paper, Beam Pattern Scanning (BPS), a transmit diversity technique, is compared with two well known transmit diversity techniques, space-time block coding (STBC) and space-time trellis coding (STTC). In BPS (also called beam pattern oscillation), controlled time varying weight vectors are applied to the antenna array elements mounted at the base station (BS). This creates a small moveme...

In the article there are mentioned combined discrete dynamic systems and analysis of their power spectrum especially aimed to the event activated part of the system. Combined dynamic systems, also called hybrid systems are the fusion result of the time-driven and event activated systems. System consists of a combination of cyclically recurring processes in each period of processing and the stoc...
