Optimal Networked Control Systems with MATLAB (Paperback): Jagannathan Sarangapani, Hao Xu Optimal Networked Control Systems with MATLAB (Paperback)
Jagannathan Sarangapani, Hao Xu
R2,094 Discovery Miles 20 940 Ships in 12 - 17 working days

Optimal Networked Control Systems with MATLAB (R) discusses optimal controller design in discrete time for networked control systems (NCS). The authors apply several powerful modern control techniques in discrete time to the design of intelligent controllers for such NCS. Detailed derivations, rigorous stability proofs, computer simulation examples, and downloadable MATLAB (R) codes are included for each case. The book begins by providing background on NCS, networked imperfections, dynamical systems, stability theory, and stochastic optimal adaptive controllers in discrete time for linear and nonlinear systems. It lays the foundation for reinforcement learning-based optimal adaptive controller use for finite and infinite horizons. The text then: Introduces quantization effects for linear and nonlinear NCS, describing the design of stochastic adaptive controllers for a class of linear and nonlinear systems Presents two-player zero-sum game-theoretic formulation for linear systems in input-output form enclosed by a communication network Addresses the stochastic optimal control of nonlinear NCS by using neuro dynamic programming Explores stochastic optimal design for nonlinear two-player zero-sum games under communication constraints Treats an event-sampled distributed NCS to minimize transmission of state and control signals within the feedback loop via the communication network Covers distributed joint optimal network scheduling and control design for wireless NCS, as well as the effect of network protocols on the wireless NCS controller design An ideal reference for graduate students, university researchers, and practicing engineers, Optimal Networked Control Systems with MATLAB (R) instills a solid understanding of neural network controllers and how to build them.

Trustworthy Policies for Distributed Repositories (Paperback): Reagan W. Moore, Hao Xu, Mike Conway, Arcot Rajasekar, Jon... Trustworthy Policies for Distributed Repositories (Paperback)
Reagan W. Moore, Hao Xu, Mike Conway, Arcot Rajasekar, Jon Crabtree
R1,319 Discovery Miles 13 190 Ships in 10 - 15 working days

A trustworthy repository provides assurance in the form of management documents, event logs, and audit trails that digital objects are being managed correctly. The assurance includes plans for the sustainability of the repository, the accession of digital records, the management of technology evolution, and the mitigation of the risk of data loss. A detailed assessment is provided by the ISO-16363:2012 standard, "Space data and information transfer systems-Audit and certification of trustworthy digital repositories." This book examines whether the ISO specification for trustworthiness can be enforced by computer actionable policies. An implementation of the policies is provided and the policies are sorted into categories for procedures to manage externally generated documents, specify repository parameters, specify preservation metadata attributes, specify audit mechanisms for all preservation actions, specify control of preservation operations, and control preservation properties as technology evolves. An application of the resulting procedures is made to enforce trustworthiness within National Science Foundation data management plans.

MWW-Type Titanosilicate - Synthesis, Structural Modification and Catalytic Applications to Green Oxidations (Paperback, 2013... MWW-Type Titanosilicate - Synthesis, Structural Modification and Catalytic Applications to Green Oxidations (Paperback, 2013 ed.)
Peng Wu, Hao Xu, Le Xu, Yueming Liu, Mingyuan He
R1,807 Discovery Miles 18 070 Ships in 10 - 15 working days

This book provides a comprehensive review of a new generation of selective oxidation titanosilicate catalysts with the MWW topology (Ti-MWW) based on the research achievements of the past 12 years. It gives an overview of the synthesis, structure modification and catalytic properties of Ti-MWW. Ti-MWW can readily be prepared by means of direct hydrothermal synthesis with crystallization-supporting agents, using dual-structure-directing agents and a dry-gel conversion technique. It also can be post-synthesized through unique reversible structure transformation and liquid-phase isomorphous substitution. The structural conversion of Ti-MWW into the materials usable for processing large molecules is summarized. Taking advantage of the structure diversity of the lamellar precursor of Ti-MWW, it can be fully or partially delaminated, and undergo interlayer silylation to obtain a novel structure with larger porosity. In the selective oxidation (alkene epoxidation and ketone/aldehyde ammoximation) with hydrogen peroxide or organic peroxide as an oxidant, the unique catalytic properties of Ti-MWW are described in comparison to conventional titanosilicates such as TS-1 and Ti-Beta.

Hua Song, Jack Jarvis, Shijun Meng, Hao Xu, Zhaofei Li, …
R3,982 Discovery Miles 39 820 Ships in 10 - 15 working days

This book discusses effective and alternative uses for natural gas (NG) and highlights the utilization of NG in the field of methane activation and chemical production. It details the techniques used during the reforming process of petrochemical and bio-derived fuels and it presents cutting-edge research that describes the utilization of NG that enables it to be more cost-effective and eliminate the expensive greenhouse gas emitting process of hydrogen production. The book addresses three major topics: NG use in upstream heavy oil and bitumen upgrading, NG and its use in downstream oil refining through co-aromatization of various feeds in the petrochemical industry, and NG use in the upgrading of bio-derived fuels and discusses alternative uses of NG. In-depth chapters demonstrate uses for NG beyond heating homes, through catalysis and in-situ hydrogen donation, and its potential applications for the petrochemical and biofuel industries.
