We investigate the problem of a decomposition of a dissipative dynamical map, which is used in quantum dynamics of a finite open quantum system, into two distinct types of mapping on a Hilbert-Schmidt space of quantum states represented by density matrices. One type corresponds to reversible behaviours, while the other to irreversible characteristics. For a finite dimensional system, in which o...
Abstract Based on an analysis of the results original research performed in Laboratory Sorption Methods Vernadsky Institute Geochemistry and Analytical Chemistry Russian Academy Sciences within project “Mathematical Chromatograph,” review covers aim strategy imitation modeling high-performance chromatography; associated problems theory intermolecular interactions; classifications polar stationa...
Valuations of dense near polygons were introduced in [9]. A valuation of a dense near polygon S = (P,L, I) is a map f from the point-set P of S to the set N of nonnegative integers satisfying very nice properties with respect to the set of convex subspaces of S. In the present paper, we give an alternative definition of the notion valuation and prove that both definitions are equivalent. In the...
A spiking neural network (SNN) model trained with spiking-timingdependent-plasticity (STDP) is proposed to perform a 2D co-ordinate transformation of the polar representation of an arm position to a Cartesian representation in order to create a virtual image map of a haptic input. The position of the haptic input is used to train the SNN using STDP such that after learning the SNN can perform t...
The combination of color image and depth map significantly improves the segmentation. The Kinect sensor with pan/tilt motorized movement captures both images and segments them separately by the Grab Cut method. The resulting contours are converted to polar coordinates. After the floor plane detection, corresponding "depth" and "color" contours are combined such that the importance of depth /col...
Research activities and research output, in general, have increased, keep increasing vastly, so too is on the polar regions including Svalbard Arctic. Major commercial publishers built subscription-based services which present literature for a fee. As Open Science open access to data gaining momentum, there distinct need powerful discovery tools that can harvest datasets form - free of charge. ...
In contrast to the network security that relies on upper-layer encryption for confidentiality and authenticity of communications, physical layer (PLS) exploits uniqueness randomness channel encrypt information enhance system. this paper, we study PLS a polar-coded wireless communication To be more specific, leverage unique properties in polar code construction propose quality indicator (CQI)-ba...
A unique feature of polarization-sensitive Mueller optical coherence tomography is that, by measuring Jones or Mueller matrices, it can reveal the complete polarization properties of biological samples, even in the presence of diattenuation. We map local polarization properties for the first time to our knowledge by using polar decomposition in combination with least-squares fitting to differen...
In the course of 71 days in lunar orbit, from 19 February to 3 May 1994, the Clementine spacecraft acquired just under two million digital images of the moon at visible and infrared wavelengths. These data are enabling the global mapping of the rock types of the lunar crust and the first detailed investigation of the geology of the lunar polar regions and the lunar far side. In addition, laser-...
Introduction: In this study, Antibacterial and antioxidant activities of the essential oil and methanolic extract of the endemic plant, Zataria multiflora Boiss. have been studied. Method: The antioxidant potential of the samples was evaluated using two separate methods of inhibition of free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ammonium thiocyanate systems. Antibacterial activity wa...
