Introduction Who We Are The USA Computing Olympiad fosters pre-college computing through training, contests, and international competitions. A handful of coaches organizes these features and also chaperone students who represent the USA in internati
With the continuous development of science and technology, People have higher request to the accuracy of the time calculate. How the clock work more precisely？ How to allow them a better service to our lives? Clearly the traditional clock can not me
机械密封又称端面密封(Mechanical End Face Seal),是旋转轴用动密封。机械密封性能可靠,泄漏量小,使用寿命长,功耗低,毋需经常维修,且能适应与生产过程自动化和高温、低温、高压、真空、高速、以及各种强腐蚀性介质、含固体颗粒介质等苛刻工况的密封要求。本设计主要围绕206型釜用机封的设计来介绍釜用机封的设计过程及设计思路！

The content includes convex sets, functions, and optimization problems, basics of convex analysis, least-squares, linear and quadratic programs, semidefinite programming, minimax, extremal volume, and other problems, optimality conditions, duality t
Thin films used for optical components require improvements in their mechanical properties and long-term stability. We examine the influence of substrate weathering on optical thin films. The light scattering of TiO2 thin films increased as the subst
Mechanical characterization of human red blood cells (RBC) is crucial to the study of the pathology, drug screening, clinical diagnosis, and treatment of Parkinson’s disease. Oxidative stress has been found to be a dominant factor among the causes of
A scheme of strong coupling between the double electron spins and the quantized nano-mechanical harmonic.oscillator is proposed based on the diamond nitrogen vacancy (NV)color center. A two-dimensional entangled state of.two qubits is prepared by
Since changes in mechanical properties of biological tissues are often closely related to pathology, the viscoelastic properties are important physical parameters for medical diagnosis. A photoacoustic (PA) phase-resolved method for noninvasively cha
A modeling method to extract the mechanical properties of ultra-thin films (10–100 nm thick) from experimental data generated by indentation of freestanding circular films using a spherical indenter is presented. The relationship between the mechanic
