Описание: In-operation vibration monitoring for complex mechanical structures and rotating machines is of key importance in many industrial areas such as aeronautics (wings and other structures subject to strength), automobile (gearbox mounting with a sports car body), rail transportation, power engineering (rotating machines, core and pipes of nuclear power plants), and civil engineering (large buildings subject to hurricanes or earthquakes, bridges, dams, offshore structures). Tools for the detection and the diagnosis of small changes in vibratory characteristics are particularly useful to set up a prevenve maintenance policy based on the actual evolution of the state of the monitored machine or structure, as opposed to systematic a priori planning. Ambient Vibration Monitoring is the backbone of such structural assessment monitoring and control. It provides the possibility to gain useful data under ambient conditions for the assessment of structures and components. Written by a widely respected authority in this area, Ambient Vibration Monitoring describes the current practice of ambient vibration methodologies illustrated by a number of practical examples. Designed to aid the practical engineer with their understanding of the topic, it is the culmination of many years of practical research and includes numerous real world' examples. It also provides information on applicable solutions. This book will enable not only practitioners (in civil, mechanical and aerospace engineering), but also researchers and students, to learn more about the theory and practical applications of this subject.
Описание: This book is a collection of articles covering the six lecture courses given at the CISM School on this topic in 2008. It features contributions by established international experts and offers a coherent and comprehensive overview of the state-of-the art research in the field, thus addressing both postgraduate students and researchers in aerospace, mechanical and civil engineering.

Описание: Explaining complex ideas in an easy to understand way, Randall provides a comprehensive survey of the applications of vibration analysis to the condition monitoring of machines, reflecting the natural progression of these systems by presenting the fundamental material and then moving onto detection, diagnosis and prognosis. Sections include vibration signals from rotating and reciprocating machines, basic signal processing techniques, fault detection, diagnostic techniques, and prognostics. Up to date research results are presented, and a number of exercises are included for each chapter, many based on Matlab, to illustrate basic points as well as to facilitate the use of the book as a textbook for courses in the topic. Much needed, up-to-date survey of the applications of vibration analysis to the condition monitoring of machines Authored by an internationally recognised authority in the area of condition monitoring Explains complex ideas in an easy to understand way. Accompanied by a website housing exercises along with data sets and implementation code in Matlab for some of the methods as well as other pedagogical aids.
Описание: This monograph addresses the systematic representation of the methods of analysis developed by the authors as applied to such systems. Particular features of dynamic processes in such systems are studied. Special attention is given to an analysis of different resonant phenomena taking unusual and diverse forms. All solutions are transformed to the final analytical expressions permitting clear mechanical interpretation. These methods are applied to the analysis of mechanical systems designed for the generation and transformation of intensive impulsive processes or structures exposed to such a nonlinear dynamic loading. These are vibro-impact processes due to intermittent unilateral contacts of the structure elements, created by backlashes in joints and kinematic pairs, during opening and closing of cracks etc. New mechanical effects are described. Some engineering problems are solved using a combination of analytical technique and modern simulation tools.
Описание: The 1948 Genocide Convention has suddenly become a vital legal tool in the international campaign against impunity. The succinct provisions of the Convention are now being interpreted in important judgements by the International Court of Justice, the ad hoc Tribunals for the former Yugoslavia and Rwanda, and a growing number of domestic courts. In this definitive work William A. Schabas focuses on the judicial interpretation of the Convention, debates in the International Law Commission, political statements in bodies like the General Assembly of the United Nations, and the growing body of case law. Detailed attention is given to the concept of protected groups, to the quantitative dimension of genocide, to problems of criminal prosecution including defenses and complicity, and to issues of international judicial cooperations such as extradition. He also explores the duty to prevent genocide, and the consequences this may have on the emerging law of humanitarian intervention.

Описание: Engineers are becoming increasingly aware of the problems caused by vibration in engineering design, particularly in the areas of structural health monitoring and smart structures. Vibration is a constant problem as it can impair performance and lead to fatigue, damage and the failure of a structure.

Описание: Presents the modeling of vibrations of complex structures coupled with acoustic fluids in the low and medium frequency ranges. This book devotes to mechanical models, variational formulations and discretization for calculating linear vibrations in the frequency domain of complex structures.
Описание: This book presents recent advances in the application of Lyapunov's method for distributed parameter systems to the control of vibration and noise. The material is appropriate for graduate and advanced undergraduate students as well as academic and industrial researchers in engineering and mathematics. The book uses detailed examples to introduce modeling, control theory, and mechatronic implementation for distributed vibration and noise applications. Adaptive, output feedback controllers are shown to asymptotically stabilize distributed vibration and noise and to learn system parameters. Visual feedback control using high speed video and setpoint regulation for systems with rigid body modes are presented. The book provides readers with the tools to model distributed vibration and noise systems, design model-based controllers that guarantee stability and robustness, and implement the controllers with the appropriate sensing, actuation, and control hardware and software.

Описание: Efforts at modelling practical problems in foundation analysis using a strength-of-materials approach have developed the concept of the conical bar or beam as a tool. Such models can be used to model a foundation in a dynamic soil-structure interaction analysis with a variation of the properties with depth. This book talks about this approach.
