With resources at a premium, and ecological concerns paramount, the need for clean, efficient and low-cost processes is one of the most critical challenges facing chemical engineers. The ability to control these processes, optimizing one, two or several variables has the potential to make more substantial savings in time, money and resources than any other single factor. Building on the success of the previous editions, this new third edition of A Real-Time Approach to Process Control employs both real industry practice and process control education without the use of complex or highly mathematical techniques, providing a more practical and applied approach. Updated throughout, this edition: • Includes a brand new chapter on Model predictive Control (MPC) • Now includes wireless and web-based technologies • Covers bio-related systems • Details the new multivariable control measure developed by the authors • Includes PowerPoint slides and solutions to Workshop problems on the accompanying website: http://www.wiley.com/go/svrcek-real-time-3e From the reviews of previous editions: “Would appeal to practising engineers due to its “hands on” feel for the subject matter. But more importantly, the authors present these concepts as fundamentals of chemical engineering, in a way that is consistent with how professor teach at the universities.” –Chemical Engineering Process (CEP) “The book has been beautifully crafted” –Engineering Subject Centre “Provides a refreshing approach to the presentation of process analysis and control” –The Chemical Engineer

Success in the continuous process industries depends upon the ability to adapt to the demands of global supply chains in real-time. Thus, process plants must be designed to be easily reconfigured as and when necessary. “A Distributed Coordination Approach to Reconfigurable Process Control” presents research that addresses this issue, via developing a new distributed framework that will enable the building of a process control system that is capable of reconfigurability. This framework views the process as a set of readily-integrated, modular process elements, which operate relatively independently and are each supported by a degree of stand-alone decision-making capability. The rationale and benefits of moving towards the new approach is demonstrated by means of a worked example of a real process plant. The research will also help end-users to gain an understanding of the economic aspects of material flows across their plants, and the ways in which their processes can be integrated across the enterprise.

An uncomfortable observation in the Shift Logs and Process Control records of most aluminum smelting plants is that process control failures, large and small, happen every day. Although only a small fraction of these failures give rise to catastrophic events, the difference between a disaster we read about and a failure which, although expensive, has no irreversible consequences, is only chance. Control for Aluminum Production and Other Processing Industries exemplifies new control thinking fused with an understanding of process variability, and how to diagnose abnormalities and their causes in aluminum production plants. Many real life examples in the book demonstrate the importance of human behavior and a scientific, questioning approach in the control of a technologically complex process. Written from the perspective of production staff and management, the book also gives readers a view into the human aspects of accidents and their analogy with failures in control of production. Production plants regularly experience more control failures than successes and staff must continuously strive to establish stability and control of their process. Through on-the-job experiences of the authors and their industry colleagues, the control experiences described in this book provide readers with a foundation for building their own robust control rationale and a framework for avoidance of plant control problems.

Scheiß auf positives Denken sagt Mark Manson. Die ungeschönte Perspektive ist ihm lieber. Wenn etwas scheiße ist, dann ist es das eben. Und wenn man etwas nicht kann, dann sollte man dazu stehen. Nicht jeder kann in allem außergewöhnlich sein und das ist gut so. Wenn man seine Grenzen akzeptiert, findet man die Stärke, die man braucht. Denn es gibt so viele Dinge, auf die man im Gegenzug scheißen kann. Man muss nur herausfinden, welche das sind und wie man sie sich richtig am Arsch vorbeigehen lässt. So kann man sich dann auf die eigenen Stärken und die wichtigen Dinge besinnen und hat mehr Zeit, sein Potential gänzlich auszuschöpfen. Die subtile Kunst des darauf Scheißens verbindet unterhaltsame Geschichten und schonungslosen Humor mit hilfreichen Tipps für ein entspannteres und besseres Leben. Damit man seine Energie für sinnvolleres verwendet als für Dinge, die einem egal sein können.

This book deals with transportation processes denoted as the Real-time Distribution of Perishable Goods (RDOPG). The book presents three contributions that are made to the field of transportation. First, a model considering the minimization of customer inconvenience is formulated. Second, a pro-active real-time control approach is proposed. Stochastic knowledge is generated from past request information by a new forecasting approach and is used in the pro-active approach to guide vehicles to request-likely areas before real requests arrive there. Various computational results are presented to show that in many cases the pro-active approach is able to achieve significantly improved results. Moreover, a measure for determining the structural quality of request data sets is also proposed. The third contribution of this book is a method that is presented for considering driver inconvenience aspects which arise from vehicle en-route diversion activities. Specifically, this method makes it possible to restrict the number of performed vehicle en-route diversion activities.​

Consumers today expect extremely realistic imagery generated in real time for interactive applications such as computer games, virtual prototyping, and scientific visualisation. However, the increasing demands for fidelity coupled with rapid advances in hardware architecture pose a challenge: how do you find optimal, sustainable solutions to accommodate both speed of rendering and quality? Real-Time Rendering: Computer Graphics with Control Engineering presents a novel framework for solving the perennial challenge of resource allocation and the trade-off between quality and speed in interactive computer graphics rendering. Conventional approaches are mainly based on heuristics and algorithms, are largely application specific, and offer fluctuating performance, particularly as applications become more complex. The solution proposed by the authors draws on powerful concepts from control engineering to address these shortcomings. Expanding the horizon of real-time rendering techniques, this book: Explains how control systems work with real-time computer graphics Proposes a data-driven modelling approach that more accurately represents the system behaviour of the rendering process Develops a control system strategy for linear and non-linear models using proportional, integral, derivative (PID) and fuzzy control techniques Uses real-world data from rendering applications in proof-of-concept experiments Compares the proposed solution to existing techniques Provides practical details on implementation, including references to tools and source code This pioneering work takes a major step forward by applying control theory in the context of a computer graphics system. Promoting cross-disciplinary research, it offers guidance for anyone who wants to develop more advanced solutions for real-time computer graphics rendering.

Human and animal vision systems have been driven by the pressures of evolution to become capable of perceiving and reacting to their environments as close to instantaneously as possible. Casting such a goal of reactive vision into the framework of existing technology necessitates an artificial system capable of operating continuously, selecting and integrating information from an environment within stringent time delays. The YAP (Vision As Process) project embarked upon the study and development of techniques with this aim in mind. Since its conception in 1989, the project has successfully moved into its second phase, YAP II, using the integrated system developed in its predecessor as a basis. During the first phase of the work the "vision as a process paradigm" was realised through the construction of flexible stereo heads and controllable stereo mounts integrated in a skeleton system (SA V A) demonstrating continuous real-time operation. It is the work of this fundamental period in the V AP story that this book aptly documents. Through its achievements, the consortium has contributed to building a strong scientific base for the future development of continuously operating machine vision systems, and has always underlined the importance of not just solving problems of purely theoretical interest but of tackling real-world scenarios. Indeed the project members should now be well poised to contribute (and take advantage of) industrial applications such as navigation and process control, and already the commercialisation of controllable heads is underway.
