"Two-dimensional materials have had widespread applications in nanoelectronics, catalysis, gas capture, water purification, energy storage and conversion. Initially based around graphene, research has since moved on to looking at alternatives, including transitions metal dichalcogenides, layered topological insulators, metallic mono-chalcogenides, borocarbonitrides and phosphorene. This book provides a review of research in the field of these materials, including investigation into their defects, analysis on hybrid structures focusing on their properties and synthesis, and characterization and applications of 2D materials beyond graphene. It is designed to be a single-point reference for students, teachers and researchers of chemistry and its related subjects, particularly in the field of nanomaterials."--Publisher's website.

"An underpinning force in Singapore's remarkable 50-year transformation into a sophisticated world-class city, engineering has contributed significantly to the nation's economic, infrastructural and social developments. A joint publication by The Institution of Engineers, Singapore, and World Scientific Publishing, to celebrate Singapore's 50th birthday, 50 Years of Engineering in Singapore brings to life the extraordinary engineering feats across multiple disciplines and tells the stories of these exceptional engineers who, with their determinations and courage, turned the little red dot into a jewel of a city. A vibrant record of engineering excellence, the publication traces the goliath challenges impeding the nation's growth over the past five decades, and the engineering innovations that brought about wealth creation, higher standards of living, and enhanced liveability. This compendium covers land transportation (ERP system, MRT and LRT, roads and buses system); water management and engineering; energy (supply and maintenance); manufacturing in the areas of electronics, precision engineering, chemical and pharmaceutical/bio-medical engineering; housing/cities/infrastructure and land use (reclamation and underground); air and sea hub; and telecommunications, ICT and software."-- Provided by publisher.

In this book, two kinds of analysis based on acoustic emission recorded during mechanical tests are investigated. In the first, individual, analysis, acoustic signature of each damage mechanism is characterized. So with a clustering method, AE signals that have similar shapes or similar features can be group together into a cluster. Afterwards, each cluster can be linked with a main damage. The second analysis is based on a global AE analysis, on the investigation of liberated energy, with a view to identify a critical point. So beyond this characteristic point, the criticality can be modeled with a power-law in order to evaluate time to failure.

This book is devoted to the mathematical analysis of the numerical solution of boundary integral equations treating boundary value, transmission and contact problems arising in elasticity, acoustic and electromagnetic scattering. It serves as the mathematical foundation of the boundary element methods (BEM) both for static and dynamic problems. The book presents a systematic approach to the variational methods for boundary integral equations including the treatment with variational inequalities for contact problems. It also features adaptive BEM, hp-version BEM, coupling of finite and boundary element methods - efficient computational tools that have become extremely popular in applications. Familiarizing readers with tools like Mellin transformation and pseudodifferential operators as well as convex and nonsmooth analysis for variational inequalities, it concisely presents efficient, state-of-the-art boundary element approximations and points to up-to-date research. The authors are well known for their fundamental work on boundary elements and related topics, and this book is a major contribution to the modern theory of the BEM (especially for error controlled adaptive methods and for unilateral contact and dynamic problems) and is a valuable resource for applied mathematicians, engineers, scientists and graduate students.

New image processing tools and data-processing network systems have considerably increased the volume of transmitted information such as 2D and 3D images with high resolution. Thus, more complex networks and long processing times become necessary, and high image quality and transmission speeds are requested for an increasing number of applications. To satisfy these two requests, several either numerical or optical solutions were offered separately. This book explores both alternatives and describes research works that are converging towards optical/numerical hybrid solutions for high volume signal and image processing and transmission. Without being limited to hybrid approaches, the latter are particularly investigated in this book in the purpose of combining the advantages of both techniques. Additionally, pure numerical or optical solutions are also considered since they emphasize the advantages of one of the two approaches separately.

This book presents recent advances in the field of computational coupling and contact mechanics with particular emphasis on numerical formulations and methodologies necessary to solve advanced engineering applications.Featuring contributions from leading experts and active researchers in these fields who provide a detailed overview of different modern numerical schemes that can be considered by main numerical methodologies to simulate interaction problems in continuum mechanics.A number of topics are addressed, including formulations based on the finite element method (FEM) and their variants (e.g. isogeometric analysis or standard and generalized high-order FEM: hp-FEM and GFEM, respectively), the boundary element method (BEM), the material point method (MPM) or the recently proposed finite block method (FBM), among many more.Written with PhD students in mind, Advances in Computational Coupling and Contact Mechanics also includes the most recent numerical techniques which could be served as reference material for researchers and practicing engineers. All chapters are self-contained and can be read independently, with numerical formulations accompanied by practical engineering applications.
