The newly developed phase-shift controlled bidirectional DC-DC converter has the conventional features of phase-shifted converters, including zero-voltage switching (ZVS) and constant switching frequency. However, it has been improved by developing a bi-directional power flow capability and applying synchronous rectification, hence the on-state voltmge drop of the active devices are small.

Global and local regularities of functions are analyzed in anisotropic function spaces, under the common framework supplied by hyperbolic wavelet bases. Local and directional regularity features are characterized by means of global quantities derived from the coefficients of hyperbolic wavelet decompositions. A multifractal analysis is introduced, that jointly accounts for scale invariance and ...

A detection scheme is presented for maneuvering affordance in noisy imagery. By introducing a mental maneuvering process within an intentional coordinate system, image features are assumed to be represented in terms of directional Fourier images. The detectability of affordance patterns has been verified through experimental studies.

Two apparently contradictory insights about sign language can be made compatible within a formal semantic analysis: (i) the claim that directional verbs incorporate agreement markers/pronouns (e.g. Lillo-Martin and Meier 2011); (ii) the observation that directional verbs have an iconic component (e.g. Liddell 2003). I sketch formal rules that integrate iconic requirements with standard semantic...

We introduce a continuous scale wavelet detector. Our algorithm was able to detect a mass that could not be seen using conventional windowing and leveling or traditional methods of contrast enhancement. An artifact free enhancement algorithm based on overcomplete multiscale wavelet analysis is then presented. The novelty of this algorithm lies in its detection of directional features and remova...

Abstract: This paper presents a trajectory controller for an omni-directional mobile robot. The controller presents important features, as the possibility of defining different translation velocities and angular positions to the robot during the trajectory following. The parameters of the controller are optimizated based on trajectory following simulations, with the mobile robot model. Simulati...

In this paper, we propose a novel face recognition method for the one sample problem. This approach is based on local appearance feature extraction using directional multiresolution decomposition offered by dual tree complex wavelet transform (DT-CWT). It provides a local multiscale description of images with good directional selectivity, effective edge representation and invariance to shifts a...

In open field arenas, Drosophila adults exhibit a preference for arena boundaries over internal walls and open regions. Herein, we investigate the nature of this preference using phenomenological modeling of locomotion to determine whether local arena features and constraints on movement alone are sufficient to drive positional preferences within open field arenas of different shapes and with d...
