This book is for EVERYONE
At the beginning of the new millennium the PID controller continues
to be a key component of industrial control. During this century
many different structures of control have been proposed to overcome
the limitation of the PID controllers. Because of their simplicity
and usefulness, they give a very useful solution to an important
part of the industrial processes. The present-day structure of PID controllers is quite different
from the original analog PID controllers. Now the implementation of
the PID is based on digital design, these digital PIDs include many
algorithms such as anti-wind-up, auto-tuning, adaptive, and fuzzy
fine tuning to improve their performances, but the basic actions
remain the same. During the last two decades, the general reluctance of
researchers to use PID controllers has begun to disappear. Many of
the new capabilities of digital PID controllers have been
introduced by the research community. The industrial control users
apply these innovations easily, even enthusiastically. PID control
has become one of the most important ways for the scientific
specialist in control and the users of industrial control to work
together. This workshop was organized so that the scientific world and the
industrial control world could meet and discuss the present and
future use of PID controllers - the successes and failures of their
use and how to determine the limits of performances. This workshop
was also useful for learning about control history, since the
origin and evolution of PID control can provide us with keys for
new development and designs.

This book describes fluorocarbons gases' preparation process, properties, applications and their evolution over time. The impact of fluorocarbons on the ozone layer and global and the development to mitigate those effects have been specially emphasized. The first major industrial fluorinated compound was developed in the 1920's, to replace ammonia and sulfur dioxide refrigerants, at the General Motors Frigidaire Division by Thomas Midgley, Jr. and Albert Leon Henne. They developed a family of fluorocarbons trademarked Freon(R) for auto air conditioning units revolutionizing the auto industry. Other applications were developed over time including fire extinguishers, propellants, blowing agents, cleaners, anesthesia, artificial blood and others impacting every facet of life. In spite of being in broad global use for nearly a century, fluorocarbon gases have gone through great evolution during the last few decades. In the 1980s it was discovered chlorofluorocarbon (CFC) gases are harmful to the ozone layer, mainly because of their chlorine content. Chlorine was released in the upper atmosphere when chlorofluorocarbon molecules were broken down by the high energy cosmic radiation. CFCs were progressively banned following the Montreal Protocol of 1987. CFCs were replaced by fluorinated gases containing either less chlorine (hydrofluoro-chlorocarbons, or HCFCs), which are much less damaging (about 90% less) to the ozone layer or with fluorinated gases containing no chlorine, i.e. hydrofluorocarbons or HFCs. HFC have no impact on the ozone layer but impact global warming detrimentally. HFCs are usable without need for changes to the existing refrigeration or air conditioning installations. More recently hydrofluoroolefins (HFOs), which have little or no negative impact on global warming, have been developed to replace or reduce the use of HFCs. HFOs are used as single compounds or in blends. Research and development continues to develop and replace the HCFCs and HFCs completely with environmentally friendly products. Concise Handbook of Fluorocarbon Gases presents a reference and text for the commercial fluorocarbon gases which have great many application in a wide range of industries such as refrigeration and air conditioning, as well as consumer products.

Innovation is the life blood of practically every organization. Innovation drives growth, development, and prosperity for many organizations and geographical areas. Sometimes, innovation thrives within a certain geographical location or in certain organizations that are known for their innovative approaches. This outstanding new volume will demonstrate how to measure the success of innovation in all types of organizations. In the last decade, there have been tremendous investments in creativity and innovations sponsored by companies, cities, states, countries, universities, NGO's, and even non-profits. With the magnitude of emphasis on creativity and innovation, the sponsors and key stakeholders will demand to know the value of these programs. The Value of Innovation: Measuring the Impact and ROI in Creativity and Innovation Programs will show step-by-step how to measure the impact and the ROI of innovation and creativity programs. The process collects six types of data: reaction, learning, application, impact, ROI, and intangibles. Data are collected analyzed and reported using a systematic, logic model. Conservative standards create results that are both CEO and CFO friendly. This proven process has been used now in 5000 organizations and this new book adapts the method directly to this critical area of innovation, showing examples and case studies.
Toward developing a rational basis for the metal cutting process. From the introduction: The economic importance of the cutting process may be appreciated by the single observation that nearly every device in use in our complex society has one or more machined surfaces or holes. There are several reasons for developing a rational approach to the cutting problem: 1. To improve cutting techniques-even minor improvements are of major importance in high volume production. 2. To produce products of greater precision and of greater useful life. 3. To increase the rate of production and produce a greater number and variety of products with the tools available. In this treatment of the subject we will consider the cutting process in fundamental terms. The objective is to explain a number of commonly observed results rather than to present a large mass of empirical constants and a large number of empirical relationships of limited applicability.
The recent explosion of interdisciplinary research has fragmented the knowledge base surrounding renewable polymers. The Chemistry of Bio-based Polymers 2nd edition brings together, in one volume, the research and work of Professor Johannes Fink, focusing on biopolymers that can be synthesized from renewable polymers. After introducing general aspects of the field, the book's subsequent chapters examine the chemistry of biodegradable polymeric types sorted by their chemical compounds, including the synthesis of low molecular compounds. Various categories of biopolymers are detailed including vinyl-based polymers, acid and lactone polymers, ester and amide polymers, carbohydrate-related polymers and others. Procedures for the preparation of biopolymers and biodegradable nanocomposites are arranged by chemical methods and in vitro biological methods, with discussion of the issue of "plastics from bacteria." The factors influencing the degradation and biodegradation of polymers used in food packaging, exposed to various environments, are detailed at length. The book covers the medical applications of bio-based polymers, concentrating on controlled drug delivery, temporary prostheses, and scaffolds for tissue engineering. Professor Fink also addresses renewable resources for fabricating biofuels and argues for localized biorefineries, as biomass feedstocks are more efficiently handled locally.

Although industrial processes are inherently nonlinear, many contributions for controller design for those plants are based on the assumption of a linear model of the system. However, in some cases it is difficult to represent a given process using a linear model. Model Predictive Control (MPC) is an optimal control approach which can effectively deal with constraints and multivariable processes in industries. Because of its advantages, MPC has been widely applied in automotive and process control communities. This book discusses the theory, practices and future challenges of model predictive control.
