Process Control

Petroleum engineers search through endless sources to understand oil and gas chemicals, find problems and discover solutions while operations are becoming more unconventional and driving towards more sustainable practice. Oil and Gas Chemistry Management Series brings an all-inclusive suite of tools to cover all the sectors of oil and gas chemicals from drilling to production, processing, storage, and transportation. The fourth reference in the series, Surface Process, Transportation, and Storage delivers the critical chemical oilfield basics while also covering latest research developments and practical solutions. Organized by the type of mitigation and recovery method, the engineer can fully understand how to effectively control chemistry issues, make sound decisions, and mitigate the challenges ahead. Basics include gas treating, CO2 recovery, produced water treatment, while more advanced topics cover hydrotesting water conditioning and black powder management. Supported by a list o

Most systems involved in a chemical process plant are interactive multivariable systems, to control which, the transfer function matrix model is required. This lucid book considers the identification and control of such systems. It discusses open loop and closed loop identification methods, as well as the design of multivariable controllers based on steady state gain matrix. Simple methods for designing controllers based on transfer function matrix model have been reviewed. The design of controllers for non-square systems, and closed loop identification of multivariable unstable systems by the optimization method are also covered. Several simulation examples and exercise problems at the end of each chapter further help the reader consolidate the knowledge gained. This book will be useful to any engineering student, researcher or practitioner who works with interactive, multivariable control systems.

A high school student can create deep Q-learning code to control her robot, without any understanding of the meaning of 'deep' or 'Q', or why the code sometimes fails. This book is designed to explain the science behind reinforcement learning and optimal control in a way that is accessible to students with a background in calculus and matrix algebra. A unique focus is algorithm design to obtain the fastest possible speed of convergence for learning algorithms, along with insight into why reinforcement learning sometimes fails. Advanced stochastic process theory is avoided at the start by substituting random exploration with more intuitive deterministic probing for learning. Once these ideas are understood, it is not difficult to master techniques rooted in stochastic control. These topics are covered in the second part of the book, starting with Markov chain theory and ending with a fresh look at actor-critic methods for reinforcement learning.

The US Constitution recognizes the president as the sole legal head of the executive branch. Despite this constitutional authority, the president's actual control over administration varies significantly in practice from one president to the next. Presidential Control over Administration provides a new approach for studying the presidency and policymaking that centers on this critical and often overlooked historical variable. To explain the different configurations of presidential control over administration that recur throughout history--collapse, innovation, stabilization, and constraint--O'Brien develops a new theory that incorporates historical variation in a combination of key restrictions such as time, knowledge, and the structure of government as well as key incentives such as providing acceptable performance and implementing preferred policies. O'Brien then tests the argument by tracing the policymaking process in the domain of public finance across nearly a century of history,

How China’s economic development combines a veneer of unprecedented progress with the increasingly despotic rule of surveillance over all aspects of lifeSince the mid-2000s, the Chinese state has increasingly shifted away from labor-intensive, export-oriented manufacturing to a process of socioeconomic development centered on science and technology. Ya-Wen Lei traces the contours of this techno-developmental regime and its resulting form of techno-state capitalism, telling the stories of those whose lives have been transformed—for better and worse—by China’s rapid rise to economic and technological dominance. Drawing on groundbreaking fieldwork and a wealth of in-depth interviews with managers, business owners, workers, software engineers, and local government officials, Lei describes the vastly unequal values assigned to economic sectors deemed “high-end” versus “low-end,” and the massive expansion of technical and legal instruments used to measure and control workers and capital.She

Auditing and Assurance Services: An Integrated Approach, the definitive introductory text on auditing, focuses on the auditor's decision-making process—whether during a financial statement audit or during an integrated audit of both financial statements and internal control over financial reporting. Comprehensive and up to date, the text uses examples from the complex, current global auditing environment, such as the United Kingdom's Financial Reporting Council highlighting a lack of skepticism as a major concern; the challenges of auditing crypto-assets; and the debate over climate-related risk assessment, to illustrate the nature and amount of evidence gathering needed at each engagement. Using key audit decisions—like establishing the objectives in a given audit area; identifying the risks related to the engagement; determining the evidence needed; and evaluating the evidence obtained—as its foundation, this text equips students with the skills to successfully conduct an audit accor
