This book delves into structural reliability analysis across seven comprehensive chapters. Beginning with foundational methods and key definitions, it transitions into FORM-based formulations, such as the HL-RF method and its variants, with a focus on convergence control and stability enhancement. The subsequent chapters cover gradient methods and directional conjugate gradient formulations, addressing challenges like instability control and search direction vector adjustments. A novel optimization model for Most Probable Point (MPP) search in the original space for interval-based random variables is introduced, offering a cutting-edge approach to uncertainty optimization. The book concludes with second-order reliability analysis methods and forward-looking discussions on emerging analytical perspectives in the field.

This book presents an experimental investigation of spin-mechanical phenomena in spin-lattice coupled systems. The author demonstrates that the resonant mechanical vibration of a micro magnetic mechanical oscillator changes in response to the magnetization process in the oscillator. The author also investigates a spin-current-induced volume modulation effect in a giant magnetostrictive material. The results presented here accelerate the exploration of cross-correlation effects between spintronics and micromechanics and provide insight into magnetomechanical properties associated with a spin current.

Dieses Buch fokussiert auf zwei zentrale Aspekte im Betrieb von Windparks: Entscheidungen und Steuerung. Im ersten Teil werden Entscheidungsprozesse erläutert, bei denen der Betrieb von Hybrid-Windparks von der Auswahl optimaler Alternativen zur Einspeisung von Windenergie ins Netz abhängt. Präzise Windvorhersagen sind entscheidend, um Fehler auszugleichen und mittels eines Batteriespeichersystems Reservekapazitäten ins Netz einzuspeisen. MCDM-Methoden und ein unscharfer Ansatz werden verwendet, um die besten Optionen zu bewerten. Fallstudien aus US-amerikanischen Windparks bieten numerische Lösungen. Im zweiten Teil liegt der Fokus auf der Steuerung, insbesondere der Yaw-Winkel-Steuerung zur Leistungsoptimierung der Turbinen. Eine Transferfunktions-basierte Methode zur Steuerung des Wirbelzentrums wird vorgestellt, begleitet von lidar-basierten Simulationen und adaptiven Steuerungsstrategien für verschiedene Windparklayouts. Die Auswirkungen des Yaw-Winkels auf die Betriebskosten des Batteriespeichersystems werden analysiert, unterstützt durch Fallstudien aus den USA und Dänemark.

This book methodically details the formulations and approaches to solve boundary value problems, which are essential for determining the stress–strain states in three-layer rods and plates subjected to both single and quasi-static variable loads in thermal radiation and force fields. It duly considers the complex influences on the physically nonlinear properties of the materials in each layer. The book offers several innovative analytical solutions and a numerical parametric analysis of the stress–strain scenarios in these structures. It describes the deformation of physically nonlinear media in thermoradiational fields within the small elastic-plastic deformations theory framework. The work explores variational problem-solving methods and the elastic solution method. It presents a formula for calculating the temperature within a three-layer assembly, derived by averaging the thermophysical properties of the materials across the layers'thickness. Additionally, the book includes an analysis of the attenuation of neutron flux as it passes through a three-layer element.

This book highlights the presentation of methods for studying oscillations under external periodic influence and random changes in parameters in dynamic systems with nonlinearities that have discontinuities and kinks. The analysis of dynamic systems is based on effective approaches and algorithms of the method of point mappings of Poincaré surfaces, developed by the Nizhny Novgorod Scientific School of academician A.A. Andronov. Considerable attention is paid to the study of the general picture of the possible behavior of systems and their use in solving various applied problems. Using specific examples, it is found that this research approach allows not only to advance in the study of known nonlinear features but also to discover new effects and applications. The presentation is illustrated by numerous specific examples of oscillatory strongly nonlinear systems with discontinuous nonlinearities or piecewise-continuous nonlinearities. A separate chapter is devoted to the development and use of the point mapping method for random changes in the parameters of dynamic systems, as well as in dynamic systems subject to external seismic loads. The book is intended for scientists and engineers who are engaged in research and practice activities related to the theory of nonlinear oscillations and its applications, as well as graduate students and senior undergraduate students in relevant majors.
