The first year of life is the most critical time period for structural and functional development of the human brain. Combining longitudinal MR imaging and finite strain theory, this study aimed to provide new insights into normal brain development through a biomechanical framework. Thirty-three normal infants were longitudinally imaged using MRI from 2 weeks to 1 year of age. Voxel-wise Jacobi...

In scattering theory the far field pattern describes the directional dependence of a time-harmonic wave scattered by an obstacle or inhomogeneous medium, when observed sufficiently far away from these objects. Considering plane wave excitations, the far field pattern can be written as a function of two variables, namely the direction of propagation of the incident plane wave and the observation...

This work describes the adaptive antenna array concept with seven patch elements in a hexagonal arrangement. With this structure it is possible to configure the radiation pattern to obtain directional patterns with high directivity and gain. The software IE3D, from ZELAND, was used to optimize and analyze the antenna array for applications at 1.9GHz. The return loss results and radiation patter...

This work presents a method to control the perceived distance of an auditory object by changing the directivity pattern of a loudspeaker and consequently the direct-to-reverberant ratio at the listening spot. Control of the directivity pattern is achieved by beamforming using a compact multi-driver loudspeaker unit. A small-sized cubic array consisting of six drivers is assembled, and per drive...

Many gait training programs are based on supervised learning principles: an individual is guided towards a desired gait pattern with directional error feedback. While this results in rapid adaptation, improvements quickly disappear. This study tested the hypothesis that a reinforcement learning approach improves retention and transfer of a new gait pattern. The results of a pilot study and larg...

It is very common that when a broadcaster needs to install an FM transmitting antenna within a large metropolitan area he places it on the tallest structure or building available. When the rooftop is already occupied by a large number of other types of transmitting and receiving antennas, the panel dipole antenna should be chosen. This antenna is secured to the side walls of the upper floors wi...

In this paper Micro strip Patch Antenna Array are designed and analyzed for WLAN application, which operating at S-band frequency Range of 2.4 GHz. Antenna arrays are used to achieve higher gain. The larger number of antenna elements, the better gain of antenna array is achieved. In this paper feeding element and power divider is used to design the 4 X 1 micro strip patch antenna array. Micro s...

In this paper, a wideband electronic beamforming concept applicable for UWB short pulse systems is derived and experimentally demonstrated. In particular, a Finite Impulse Response (FIR)-filter based beamforming network is configured such that an antenna array yields a desired radiation pattern within a predefined frequency range. An experimental verification of a wideband transmission system i...

Developing an intelligent pattern recognition model for electronic markets has been a vital research direction in the field. Ongoing continues learning algorithms capable of recognizing and classifying price patterns hence providing investors market analysts with better insights into time-series. In this paper, adaptive Directional Change (DC) Reinforcement Learning (RL) is proposed, so called ...
