In a typical networked control system, the control loop is closed over computer nodes that communicate through a communication network. For ordinary communication networks which introduce data loss and random delays, guaranteeing the stability of the system can be difficult. This book introduces Model Based Predictive Networked Control Systems, which is a method that can work with communication networks imposing unbounded end to end transport delay and data loss. These shortcomings are overcome using control predictions based on an explicit model of the plant in the controller node and a state machine in the actuator node. An important contribution is this framework which eliminates the need for acknowledge signals. The method and its...

Uncertainty is inevitable in problem solving and decision making. One way to reduce it, is by seeking the advice of an expert in related field. On the other hand, when computers are used to reduce uncertainty, the computer itself can become an expert in a specific field through a variety of methods. One such method is machine learning, which involves using a computer algorithm to capture hidden knowledge from data. The researchers conducted the prediction of CO2 laser cut quality to obtain singleton output using machine learning techniques. The researchers investigated a problem solving scenario for a metal cutting industry which faces some problems in determining the end quality final part considering several real life machining...

Scientific methods of enhancing gene expression including genomics, applied molecular biology, metabolic engineering, and combinatorial biosynthesis have been sufficiently developed to make a major impact on recombinant protein production. However, it appears that the combination of trial-and-error experimentation and molecular biology are not sufficient to design an optimum strategy to reach the goal. This book provides a thorough coverage of theoretical and design aspects of two engineering methodologies to overcome this shortcoming. Special emphasis was placed on the effect of the fermentation medium components of A.niger on a recombinant protein production. Statistically based experimental designs in a sequential manner were...

This work investigates the issue of weight reduction in moderately complex systems by addressing how to cascade the requirements to the individual components. Though mass can be reduced using different techniques such as material substitution or structural optimization; a systematic method is necessary to provide novel alternate solutions that enable reduction of mass of the system while satisfying the requirements and tests governing them. Such a method has been developed by exploring different aspects of achieving weight reduction through change propagation in the parameters/elements governing the system. The systematic method to generate solutions for mass reduction presented in this work includes generation of solutions at an...

Modeling production planning of a shop floor is essential in improving operational efficiency of the supply chain and thus significantly reducing costs. The uncertainties in processing times are highly undesirable for production managers. Classical linear programming models and various hybrid models have been unsuccessful to accurately represent both stochasticity in processing levels and precedence constraints. This book proposes a modified hybrid discrete event simulation-optimization model that uses chance constraints to deal with stochasticity. A comprehensive analysis has been done on the model for various levels of uncertainties and variations in input parameters. Computational studies have also been performed to test the effects...

The development of new casting alloys is needed for the next generation of pistons for turbo-charged direct injection diesel engines. For this development, an examination of effects of different alloying elements on microstructure is necessary. As statistical experiments on multi-component systems are expensive and complex, the use of thermodynamic and kinetic software is popular to calculate models of phase fractions and properties. Phases can be predicted for both equilibrium and non-equilibrium Scheil-Gulliver solidification conditions with varying amount of alloying elements. The accuracy of the model is, therefore, very important. It has been found that the Scheil prediction performs better for phase fraction simulation. It can...

Due to the capability of surface plasmons in localizing and guiding light in a sub-wavelength metal structure, surface-plasmon-based photonics or "plasmonics" offers an opportunity to merge photonics and electronics at nanoscale dimensions and makes it possible to realize very large scale electronics and photonics integration (VLSEPI). Although major breakthroughs have been made in passive plasmonic devices, including waveguides, couplers, and lenses, only a limited amount of research has been conducted on active plasmonic components, such as switches and modulators. In this book, the author describes a new concept of molecular active plasmonics (MAP) in which the precisely-controlled nanoscale mechanical motions in artificial molecular...

Il n'a donc pas besoin de bougies d'allumage. Cela est possible grace a un tres fort taux de compression (rapport volumetrique) d'environ 14:1 a 25:1, permettant d'obtenir une temperature de 700 a 900 °C. Des bougies de prechauffage sont souvent utilisees pour permettre un meilleur demarrage du moteur a froid, en augmentant la temperature de la chambre de combustion.
