This book provides an overview of computational methods based on peridynamics and nonlocal operators and their application to challenging numerical problems which are difficult to deal with traditional methods such as the finite element method, material failure being “only” one of them. The authors have also developed a higher-order nonlocal operator approaches capable of solving higher-order partial differential equations on arbitrary domains in higher-dimensional space with ease. This book is of interest to those in academia and industry. Feynman once said, calculus is the language of God. Calculus uses the partial differential derivatives (PDE) and integrals to account for various physical phenomena. On one hand, it is well known that many physical problems or physical theories are formulated concisely by partial differential equations. No matter how complicated the physical phenomena appear, the PDEs to describe the mechanism are just one/several lines of equations. Mathematically, PDEs are a combinational result of partial differential derivatives of different orders. Partial differential derivatives are defined at a point without size, in this sense, the PDEs model can be viewed as a local model. On the other hand, integral expression is defined in a finite domain, which consists of infinite points. In this sense, the integral can be viewed as a nonlocal model.

This book presents frontier research on the use of computational methods to model complex interactions in economics and finance. Artificial Intelligence, Machine Learning and simulations offer effective means of analyzing and learning from large as well as new types of data. These computational tools have permeated various subfields of economics, finance, and also across different schools of economic thought. Through 16 chapters written by pioneers in economics, finance, Computer Science, psychology, complexity and statistics/econometrics, the book introduces their original research and presents the findings they have yielded. Algorithmic thinking is gradually becoming an indispensable feature of Economics and Finance. Computational modes of thinking increasingly influence how we model individuals, organisations, market interactions and macroeconomic dynamics. Consider some topics that are traditionally of interest to economists and scholars of finance: decision-making by economic actors; mechanisms through which agents learn, adapt and thrive in uncertain, complex environments; the impact of economic decisions by individuals, firms and institutions on others in an interconnected system; emergence and diffusion of innovations; understanding volatility in financial markets; modelling aggregate, macroeconomic dynamics and associated pathologies (inflation, unemployment, inequality); and modes of exercising control through policy. All these issues are being studied using computational methods to varying degrees within the field.

Название: More-than-Moore Devices and Integration for Semiconductors

This book provides readers with a comprehensive, state-of-the-art reference for miniaturized More-than-Moore systems with a broad range of functionalities that can be added to 3D microsystems, including flexible electronics, metasurfaces and power sources. The book also includes examples of applications for brain-computer interfaces and event-driven imaging systems. The term “More-than-Moore” appeared and was readily adopted by the semiconductor community since the early 2000s, when, in addition to the decades-long focused effort to scale down the footprint of logic and memory devices according to the well-known Moore’s Law, an orthogonal trend in electronics miniaturisation had started to gain momentum. In contrast to the aggressive pursuit of increasingly more powerful computing led by Moore’s Law (More Moore), the More-than-Moore trend focuses on the combination of an increasing number of functionalities within a miniaturised system.
