In the paper work, nonlinear vibration response of functionally graded (FG) Euler–Bernoulli beam resting on elastic foundation is studied. Based von Kármán's geometric nonlinearity, partial differential governing equations describing FG are derived from Hamilton's principle and reduced to an ordinary equation with quadratic cubic terms via Galerkin's procedure. Due unsymmetrical material variation along thickness beam, neutral surface concept proposed remove stretching bending coupling...
Chatbots shifted from rule-based to artificial intelligence techniques and gained traction in medicine, shopping, customer services, food delivery, education, research. OpenAI developed ChatGPT blizzard on the Internet as it crossed one million users within five days of its launch. However, with enhanced popularity, chatbots experienced cybersecurity threats vulnerabilities. This paper discussed relevant literature, reports, explanatory incident attacks generated against chatbots. Our...
To study the anti-explosion protection effect of polyurea coating on reinforced concrete box girder, two segmental girder specimens were made at a scale 1:3, numbered as G (without coating) and PCG (with coating). The failure characteristics dynamic responses compared through conducting explosion tests. reliability numerical simulation using LS-DYNA software was verified by test results. effects different scaled distances, reinforcement ratios, strengths, thicknesses ranges studied. results...
Lithium–sulfur batteries (LSBs) are regarded as significantly potential future-oriented power sources. Nevertheless, one of the significant challenges that needs to be addressed in LSBs is lithium dendrite overgrowth. In this study, we have introduced 1% LiNO3 and 2% Y(NO3)3 (1% Li & Y) additives form an situ solid electrolyte interface (SEI) layer overcome overgrowth enhance electrochemical performance LSBs. Including (2% additive builds emergence composite passivation containing...
Food recommendation systems are becoming increasingly vital in modern society, given the fast-paced lifestyle and diverse dietary habits. Existing research implemented solutions often rely on user preferences past behaviors for recommendations, which poses significant issues. Firstly, this approach inadequately considers nutritional content of foods, potentially leading to recommendations that overly homogeneous lacking diversity. Secondly, it may result repetitive suggestions same types...
Abstract The dynamic performances of an ultra-precision fly cutting machine tool (UFCMT) has a dramatic impact on the quality machining. In this study, model UFCMT was established based transfer matrix method for multibody systems. particular, large-span scale flow field mesh created; and variation in linear angular stiffness journal thrust bearings with respect to film thickness investigated by adopting technique. proven be valid comparing characteristics obtained numerical simulation...
Abstract The performances of aerostatic bearings have an important impact on machining accuracy in the ultraprecision machine tools. In this paper, numerical simulation is performed to calculate static and dynamic a double-pad annular inherently compensated thrust bearing, while considering effects upper bearing lower bearing. results calculated by computational fluid dynamics (CFD) method are compared with finite difference (FDM) for specific model. By using polynomial fitting,...
