  • The original edition of Minds, Machines, & Evolution, published by Bantam Books in June, 1988, produced some enthusiastic responses, and readers were still tracking me down to ask how they could obtain a copy long after it had gone out of print. So, when, early in 1996, Jim Baen decided to put together a second, similar collection, Rockets, Redheads, & Revolution, we thought it would be a good idea to reissue the first also as a companion volume.

  • The miniaturization and performance improvement in semiconductor devices and integrated circuits (ICs) are expected to continue through leveraging of nanotechnologies and nanomaterials. This evolution should accelerate the System-on-a-Chip (SoC) trend, i.e., singlechip integration of multifunctional, mixed-signal electronic components, toward realizing embedded nanoelectronic systems.

  • Vertical shaft kilns are still used in some parts of the world to produce cement, predominately in China where they are currently used to manufacture nearly half of the cement produced annually (Wang 2007). A shaft kiln essentially consists of a large drum set vertically with a packed mixture of raw material and fuel traveling down through it under gravity. Parallel evolution of shaft kiln technology with the more complex dry process rotary kilns kept the mix of pyroprocessing technologies in China's cement industry more diverse than in almost any other country.

  • This tutorial is about the evolution of speech technology from research to a mature industry. Today, spoken language communication with computers is becoming part of everyday life. Thousands of interactive applications using spoken language technology— known also as “conversational machines”—are only phone calls away, allowing millions of users each day to access information, perform transactions, and get help. Speech recognition, language understanding, text-to-speech synthesis, machine learning, and dialog management enabled this revolution after more than 50 years of research.

  • It was 2538 years After the Year of the Son of Man. For six centuries mankind had been developing machines. The Ear-apparatus was discovered as early as seven hundred years before. The Eye came later, the Brain came much later. But by 2500, the machines had been developed to think, and act and work with perfect independence. Man lived on the products of the machine, and the machines lived to themselves very happily, and contentedly. Machines are designed to help and cooperate. It was easy to do the simple duties they needed to do that men might live well. And men had created them.

  • Since the first production of tools at the beginning of human presence on Earth, human evolution is linked to the invention of new tools, usually combined with new environmental adaptations. The symbiosis of man with tools and environments represents one of the main factors in human evolutionary processes. It is evident how this coupling is based on the biophysics of our bodies and the development of the social memory system called culture.

  • Evolutionary computation has been widely used in computer science for decades. Even though it started as far back as the 1960s with simulated evolution, the subject is still evolving. During this time, new metaheuristic optimization approaches, like evolutionary algorithms, genetic algorithms, swarm intelligence, etc., were being developed and new fields of usage in artificial intelligence, machine learning, combinatorial and numerical optimization, etc., were being explored.

  • The state of the art of the machine industry has experienced a rapidly accelerating evolution since the outset of the first industrial revolution. Modern machines are required to perform to varying requirements of accuracy, productivity, and surface finish requirements. It is the purpose of this discussion to establish some guidelines of machine system design to attain the desired performance requirements of accuracy, surface finish, etc. Modern industrial machines are considered as a total system comprised of the control, drive, and machine....

  • EVOLUTION OF SERVO DRIVES The word ‘‘servo’’ is a learned borrowing from Latin where it meant ‘‘slave.’’ Industrial servos had their real beginning during World War II. Some applications were in military gun control and steering control. The evolution of speed and positioning drives since the war is shown in Figure 1.

  • In this second edition of Industrial Servo Control Systems, the chapters have been updated and expanded and a new chapter has been added on servo compensating techniques. The book continues to be dedicated to the practicing engineer making the transition from academic theory to the realworld solution of engineering problems related to the application of servo drives to industrial machines. Part I focuses on the evolution and classification of servos, with descriptions of servo drive actuators, amplifiers, feedback transducers, performance, and troubleshooting techniques.

  • During the evolution of jBPM, leading up to Activiti, I took a new approach to the old problem. Initially, the focus was on state machines, but eventually we constructed an engine to match the way business people and developers collaborate. We designed the engine in such a way that it would allow business people to define the graphical flow of the process and, at the same time, give developers the opportunity to bind program logic inside the process flows. In addition, the engine was lightweight and integrated easily into any Java environment. The result was what we call embeddable BPM....
