Turbulent drag reduction by additives has long been a hot research topic. This phenomenon is inherently associated with multifold expertise. Solutions of drag-reducing additives are usually viscoelastic fluids having complicated rheological properties. Exploring the characteristics of drag-reduced turbulent flows calls for uniquely designed experimental and numerical simulation techniques and elaborate theoretical considerations. Pertinently understanding the turbulent drag reduction mecha...

This book covers: (1) the basic nomenclature and general properties of iptycenes and their derivatives; (2) the synthesis and functionalization reactions of triptycenes, pentiptycenes, higher iptycenes, heterotriptycenes, and homotriptycenes; (3) the methods for the preparation of iptycene-based polymers with different types; and (4) the ...

In this book, we collected recent results on the control of underactuated mechanical systems subject to internal uncertainties and external disturbances. The strategy developed is so universal that it is not restricted to a specific system but a large class of underactuated systems. Several benchmark systems are studied in this book, including detailed literature review, system dynamics derivation, control problem formulation, and simulation verification. The control strategy developed in ...

This book focuses on the fundamentals, technologies and properties of ion irradiation of dielectric materials (e.g. glasses, crystals) with regard to various photonic applications. It introduces readers to diverse ion-beam techniques for the fabrication and modification of micron- or nanoscale photonic structures, including optical waveguides, photonic crystals, and nanoparticle (nano-spheres and nano-rods) systems, and presents state-of-the-art advances in this multi-disciplinary research...

This book focuses on the applications of Equivalent-Small-Parameter Method (ESPM) in solving the steady-state periodic solutions, as well as stability analysis, of kinds of open-loop or closed-loop operated DC/DC converters, such as PWM, quasi-resonant and resonant ones. The analytical expressions of DC components and harmonics of state variables (inductor current and capacitor voltage) with DC/DC converters can be obtained by ESPM, which can be helpful to understand the nonlinear operatin...

在天文观测中，有不少“引力异常现象”，是既有的引力理论所无法解释的。因此，研究各种空间粒子的运动对形成力的影响，具有举足轻重的意义。本人从客观实际出发，根据恒星的粒子辐射，推导出了恒星的三个斥力公式，并且撰写了恒星斥力的文章。力的存在一定会有施力者。我反复揣摩：靠质量本身就能形成引力，这从能量守恒定律的角度看，是说不通的。进一步的推论是，引力的施力者应该存在于质量之外。经过长期思考，我认为，相邻的两个物体之间，能出现“引力”，根据引力表现出的各种特征，比较像是宇宙空间环境中漫射的神秘莫测的强透射粒子捣鬼的结果。目前，我们虽然全面探测它们有困难，但也不能轻率地否认它们的存在和作用。中微子是强透射粒子的典型代表，尤其是 。 是隐形高手，身怀绝技，最有可能是引力的肇事者。宇宙中中微子的通量，目前我们无法确知。在没有找到更有说服力的引力理论之前，要认可宇宙大爆炸理论是完全正确的，也为时尚早。2013年3月，我对强透射粒子作用于两物体之间，建立分析模型，从构造方面重新推导了引力公式，当得到 这一形式后，并...
