The paper analyses a drawn steel joint in round logs for which several types of reinforcements have been proposed.The load-carrying capacity of the reinforcements have been tested in laboratories.At the same time, numerical modelling has 4" Speakers been performed - it has focused, in particular, on rigidity of the joints during the loading process

In this paper, a novel spatial domain color image watermarking technique is proposed to rapidly and effectively protect the copyright of the color image.First, the direct current (DC) coefficient of 2D-DFT obtained in the spatial domain is discussed, and the relationship between the change of each pixel in the spatial domain and the change of the D

In most operating theatres, unused sterile instruments must be re-sterilized according to preset protocols.Protocols differ among institutions and are not based on strong scientific evidence.Objective: To determine 4" Speakers and compare the duration of sterility of small instruments packaged in double-layered linen versus plastic-paper envelopes

The future forecasting ability of machine learning (ML) makes ML a promising tool for predicting long-time quantum dissipative dynamics Door Mats of open systems.In this article, we employ nonparametric ML algorithm (kernel ridge regression as a representative of the kernel methods) to study the quantum dissipative dynamics of the widely-used spin-

The dopaminergic system is known to be involved in working memory processed by several brain regions like prefrontal cortex (PFC), hippocampus, striatum.In an 4" Speakers earlier study we could show that Levodopa but not Modafinil enhanced working memory in a T-maze only during the early phase of training (day 3), whereas the later phase remained u
