Quantum-Inspired Uncertainty Quantification

Reasonable quantification of uncertainty is a major issue of cognitive infocommunications, and logic is a backbone for successful communication. Here, an axiomatic approach to quantum logic, which highlights similarity to and differences to classical logic, is presented. The axiomatic method ensures that applications are not restricted to quantum physics. Based on this, algorithms are developed that assign to an incoming signal a similarity measure to a pattern generated by a set of training signals.

SELF-SIMILAR STRUCTURES IN BIOMECHANICS. HUMAN VIBRORECEPTORS

The concept of dynamic-fractal self-similar structures (dynamic fractal) is introduced. This concept consists in scaling the dynamic, i.e. elastic-inertial parameters of the forming cells. It is shown that a dynamic fractal decreasing in length amplifies the incoming signal along the structure. A dynamic fractal that increases in length, on the contrary, has the good vibroisolation properties, the attenuation intensity in which is higher than in the periodic structure. The dynamic properties of the Pacini corpuscle, which is a human vibration detector, are investigated. Its mechanical model is constructed. It is shown that the vibroreceptor is a dynamic fractal with parameters decreasing in length. Therefore the vibroreceptor amplifies the incoming signal, which makes it possible to detect even weak vibration effects on a person

Design of Rat-Race based Retrodirective Arrays for Backscatter Communications

Fast beaming tracking and security are important factors for the development of communication technology. A Retrodirective antenna (RDA) technique has been attenuated to one way of improving security. It has the interesting property of automatically responding to an incoming signal location without any prior knowledge of the direction of that source. The purpose of this paper is to design a Rat race coupler which acts as a Retrodirective mode in ANSYS. The resonant frequency of the coupler is 2.4 GHz. The Proposed Rat race couplers have been devised using the Glass Epoxy substrate (FR4) with dielectric constant (?r = 4.4). S parameters, radiation pattern, insertion and isolation losses are obtained from ANSYS software

Improvement of Range Estimation with Microphone Array

This paper presentsanew approach for the three-dimensional (3-D) localization of sound sources. An acoustic camera uses an angular beamforming to measure the Direction of Arrival (Do A) of an incoming signal, to localize the emission source. The acoustic sensor used in this article is the Brüel & Kjaer acoustic camera transformed to operate inabistatic mode. The transformation consists inaplacing of one of the microphones of the acoustic camera outside of its microphone array. This allows simultaneous estimation of the Do Aand the Time Difference of Arrival (TDo A) of the incoming signal(s). Such sensors were not found. The paper proposes emitter localization in range - cross range - elevation coordinates by combining estimates of TDo Aand Do Aand presents the signal processing method for that purpose. The range resolution of 0.2mwas achieved in an experiment. Experimental results were obtained using different emission sources. Adescription of resolution cell limitations is presented. The obtained results show acoustic noise source localization without the pre-metering of the range of the imaging plane, i.e., withoutaneed to use the additional range meter which is notapart of the acoustic camera. The latter is important in tasks of non-destructive testing.
