Abstract:

The problem of finding the shortest paths between all pairs of vertices in a weighted directed graph is considered. The algorithms of Dijkstra and Floyd-Warshall, homogeneous block and parallel algorithms and other algorithms of solving this problem are known. A new heterogeneous block algorithm is proposed which considers various types of blocks and takes into account the shared hierarchical memory organization and multi-core processors for calculating each type of block. The proposed heterogeneous block computing algorithms are compared with the generally accepted homogeneous universal block

This article discusses the question of assessing the probability of finding information sets in block-permutation and block-circulant matrices. Traditionally, interference-resistant coding is considered independent errors, however, in real systems they can be grouped and generate a so-called error burst. Known estimates of the probability of finding information sets are conducted for random matrices, and for correcting error bursts widespread block-permutation low density parity check codes (LDPC-codes) or block-circulant quasi cyclic codes (QC-codes) can be used.

Abstract:

Low rank matrices approximations have been used in link prediction for networks, which are usually global optimal methods and lack of using the local information. The block structure is a significant local feature of matrices: entities in the same block have similar values, which implies that links are more likely to be found within dense blocks. We use this insight to give a probabilistic latent variable model for finding missing links by convex nonnegative matrix factorization with block detection. The experiments show that this method gives better prediction accuracy than original method al

Containers transported to a container terminal are stored in container yards side by side and on top of each other, forming blocks. If a container that is not on top of the block has to be retrieved, the containers that are above the required container must be relocated before the required container is retrieved.

1. Three to eight micromolar external Mg2+ produces discrete block of the unitary inward currents through the L‐type Ca2+ channel carried by 300 mM external Li+. Like the Ca2+ block, increasing Li+ concentration decreases the Mg2+ on‐rate and increases the Mg2+ off‐rate. 2. These kinetic changes are saturating and the apparent dissociation constant (Kd) for the on‐rates in 75 mM Li+ (in activity), the same as that in the case of Ca2+ block. This suggests that Mg2+ and Ca2+ produce the discrete block at the same site. The apparent Kd for the off‐rates is 300 mM, much smaller than that in the ca

Abstract:

The uses of polymeric materials in today's world are vast. Polymers are finding applications in the microelectronics industry as dielectric insulators and photoresists, in the aerospace and automobile industry as lightweight substitutes for metals, and in biotechnology as replacement components for bone, heart, and other organs. These are just a few of the many end uses of polymers.Often, a polymer may have a particular, desirable property but processing of the polymer is difficult or the polymer's surface characteristics are undesirable. To circumvent such shortcomings there are several optio

<strong>Abstract:</strong> Humanoid Robots are enormously complex and that is why the research on humanoids spreads out over all kinds of scientific fields, from mechanics to electronics, from modeling to control and from informatics to biomechanics. This research paper is concerned with the development of a humanoid robot using edge detection technique. In the design process, the model of a humanoid robot was developed first using the simulink library tools in Matlab/Simulink environment. The guassian block convolved the input matrix with the Prewitt kernel and the block outputs two gradient

Background. The article discusses the issue of evaluating the morphometric properties of a polygon in order to form a rating matrix necessary to solve the problem of finding a path in a discrete space. This approach to solving the problem of spatial development of linear objects of land transport will be useful in solving practical problems of camera tracing. Materials and methods.The landfill in question is separated into separate territorial units, each of which has its own rating based on a set of different criteria (anthropogenic load, morphometry, etc.).

Abstract:

The Versatile Video Coding (VVC) standard was released in 2020 to replace the High Efficiency Video Coding (HEVC) standard, making it necessary to convert HEVC encoded content to VCC to exploit its compression performance, which was achieved by using a larger block size of 128 × 128 pixels, among other new coding tools. However, 80.93% of the encoding time is spent on finding a suitable block partitioning. To reduce this time, this proposal presents an HEVC-to-VVC transcoding algorithm focused on accelerating the CTU partitioning decisions. The transcoder takes different i

Abstract:

Visual recognition and localization of underwater optical beacons is an important step in autonomous underwater vehicle (AUV) docking. The main issues that restrict the use of underwater monocular vision range are the attenuation of light in water, the mirror image between the water surface and the light source, and the small size of the optical beacon. In this study, a fast monocular camera localization method for small 4-light beacons is proposed. A YOLO V5 (You Only Look Once) model with coordinated attention (CA) mechanisms is constructed.

In real-world networks, many problems imply finding the All-Pairs Shortest Paths (APSP) and their distances in a graph. Solving the large-scale APSP problem on modern muti-processor (multi-core) systems is the key for various application domains. The computational cost of solving the problem is high, therefore in many cases approximate solutions are considered as acceptable. The blocked APSP algorithms are a promising approach which can exploit many processors (cores) and their caches in parallel mode efficiently. At the same time, to our best knowledge, all blocked algorithms of the Floyd-War

Abstract KLEIN is a family of lightweight block ciphers which was proposed at RFIDSec 2011 by Gong et. al. It has three versions with 64, 80 or 96-bit key size, all with a 64-bit state size. It uses 16 identical 4-bit S-boxes combined with two AES’s MixColumn transformations for each round. This approach allows compact implementations of KLEIN in both low-end software and hardware. Such an unconventional combination attracts the attention of cryptanalysts, and several security analyses have been published. The most successful one was presented at FSE 2014 which was a truncated differential att
