This book presents several dynamic models and meta- models in order to evaluate the quality of vibration isolation in a motorcycle. All models are used to solve the engine mount optimization problem so as to minimize the forces transmitted to the frame while meeting packaging constraints. This book is divided into three main sections. The first section develops mathematical models to capture the quality of vibration isolation in a motorcycle. The second section solves the optimization problem using the models developed in the first section. The third section develops meta-models from the theoretical models in order to simplify the governing model and reduce computational effort required for solving the optimization problem. Several...

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...

Le traitement thermique du bois est un procede connu et etudie depuis plusieurs decennies. Il confere au materiau une meilleure stabilite dimensionnelle et une meilleure durabilite au detriment de ses proprietes mecaniques, notamment de sa resilience. En depit de plusieurs travaux disponibles, il reste difficile d'optimiser le gain sur les proprietes recherchees et de mettre en vis-a-vis les pertes sur les qualites que l'on voudrait preserver. Ce constat nous a conduit a mener des etudes fondamentales pour comprendre les mecanismes mis en jeux lors du traitement thermique. Les possibilites offertes en matiere de simulation numerique nous permettent de proposer une contribution innovante au probleme d'homogeneite du traitement d'une piece...

Agricultural, industrial, municipal, navigational, and recreational demand of water is met by two major sources surface water and groundwater. Compared to surface water sources which depend upon the annual rainfall and the melting of ice and snow, ground water supply is more reliable because it does not directly depend on the annual rainfall. Therefore utilization of groundwater resources is growing over the years. However unplanned use of groundwater has caused several problems in many places. Groundwater modeling is used as a major tool to understand the complex dynamic behaviour of aquifer system. This required aquifer system parameters which are very difficult to evaluate by field methods alone. Inverse modeling helps in adequate...

Vibration analysis has found widespread application for condition monitoring in a variety of applications and industries. With the continual development of cheaper and more powerful processing hardware, such systems have developed from utilizing simple checks on amplitude to those based around sophisticated spectral analysis. This book presents application of the model based diagnostic method for early detection of faults in rotating machinery. The proposed diagnostics system based on two methods – modal analysis (OMA and OMAX methods) and non-linear signals models (NARX). In the book the diagnostic system based on such modeling is presented. The proposed system was verified during research on a specialized test rig, which can generate...

Solid oxide fuel cells (SOFCs) are expected to be widely applicable for both small and large-scale power generation systems. The reason is that the SOFC is simple, highly efficient, tolerant to impurities, and can at least partially internally reform hydrocarbon fuels. A multi-physics, multi-scale model structure is proposed by integrating three submodels, i.e., a macro-continuum model, a micro-scale model (random walk model) and an atomistic-level model. This multi-scale model has the capability of handling transport mechanisms on different length scales at the same time. The coarsest macro-continuum model is first proposed to simulate all energy transport processes in an electrolyte-/anode-supported SOFC. Then a novel micro-level model...

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...

The moisture absorption behavior of the structural adhesive is commonly analyzed by just describing the characteristics of the moisture uptake versus time without relating it with the established concept of Fickian behavior. Therefore the aim of this book is to serve as a guide for undergraduate student doing final year research project, postgraduate students and researchers who do not have formal course on Fick's theory in college. The examples given are based on the author's experienced in investigating the moisture uptake of polymer. Данное издание не является оригинальным.

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...
