DOWNLOAD EBOOKAs we move further into the 21st century, despite the fact that new technologies have emerged, machining remains the key operation to achieve high productivity and precision for high-added value parts in several sectors, but recent advances in computer applications should close the gap between simulations and industrial practices. This book, “Machining Dynamics and Parameters Process Optimization”, is oriented toward the different strategies and paths when it comes to increasing productivity and reliability in metal removal processes. The topics include the dynamic characterization of machine tools, experimental dampening techniques, and optimization algorithms combined with signal monitoring.

DOWNLOAD EBOOKElectrical Circuits with Variable Parameters Including Pulsed-Control Systems focuses on the processes, methodologies, parameters, and approaches involved in the study of electrical circuits. The publication first offers information on the forced current component in an oscillatory circuit with a periodically varying inductance; free oscillations in circuits with variable parameters; and operational admittances and system functions of circuits with variable parameters. The text then examines the calculation of transients by the Fourier-series method and methods for the analysis of pulse circuits and problems of the theory of pulse and digital automatic controllers. Discussions focus on theoretical principles, frequency characteristics of impulse functions, determination of the value of the system response to an impulse disturbance at instants of time between impulses, and derivatives and integrals of impulse functions. The text ponders on the stability of circuits with variable parameters and the stability of periodic modes of operation in non-linear circuits, including the approximate method for investigating the stability of periodic modes of operation; remarks on the investigation of the stability of circuits with feedback containing parameters varying periodically (or exponentially); and analysis of the stability of pulse circuits with feedback. The publication is a dependable reference for readers and engineers interested in the study of electrical circuits.

DOWNLOAD EBOOKThe Deep Mixing Method (DMM), a deep in-situ soil stabilization technique using cement and/or lime as a stabilizing agent, was developed in Japan and in the Nordic countries independently in the 1970s. Numerous research efforts have been made in these areas investigating properties of treated soil, behavior of DMM improved ground under static and dynamic conditions, design methods, and execution techniques. Due to its wide applicability and high improvement effect, the method has become increasingly popular in many countries in Europe, Asia and in the USA. In the past three to four decades, traditional mechanical mixing has been improved to meet changing needs. New types of the technology have also been developed in the last 10 years; e.g. the high pressure injection mixing method and the method that combines mechanical mixing and high pressure injection mixing technologies. The design procedures for the DM methods were standardized across several organizations in Japan and revised several times. Information on these rapid developments will benefit those researchers and practitioners who are involved in ground improvement throughout the world. The book presents the state of the art in Deep Mixing methods, and covers recent technologies, research activities and know-how in machinery, design, construction technology and quality control and assurance. The Deep Mixing Method is a useful reference tool for engineers and researchers involved in DMM technology everywhere, regardless of local soil conditions and variety in applications.

DOWNLOAD EBOOKActivated tungsten inert gas welding process involves a method of increasing penetration capability of the arc in TIG welding. This is achieved through the application of a thin coating of activated flux onto the joint surface prior to welding. This leads to strong joint. This paper deals with the study of microstructural and mechanical properties of aluminium alloy AA-6061 weld joints using A-TIG welding. During the experiment the welding current and gas flow rate are used as variable parameters and welding speed kept as constant. In this activated TIG welding process, there were five single component fluxes which are CdCl2, SiO2, MgO, Al2O3 and TiO2 used in the initial experiment to evaluate Welding current, Gas Flow Rate, Flux by joining plates by using A-TIG welds. Based on the higher penetration of weld bead, two single component fluxes SiO2 and TiO2 were selected for actual experiment. The values of optimum welding current and gas flow rate and flux was finding out from the experiment. Welding specimen were investigated using scanning electron microscope, vicker's micro hardness test and tensile strength. The SiO2 flux produced the most noticeable effect in terms of tensile strength and micro hardness.

DOWNLOAD EBOOKThis book offers an introduction to the physics of nonlinear phenomena through two complementary approaches: bifurcation theory and catastrophe theory. Readers will be gradually introduced to the language and formalisms of nonlinear sciences, which constitute the framework to describe complex systems. The difficulty with complex systems is that their evolution cannot be fully predicted because of the interdependence and interactions between their different components. Starting with simple examples and working toward an increasing level of universalization, the work explores diverse scenarios of bifurcations and elementary catastrophes which characterize the qualitative behavior of nonlinear systems. The study of temporal evolution is undertaken using the equations that characterize stationary or oscillatory solutions, while spatial analysis introduces the fascinating problem of morphogenesis. Accessible to undergraduate university students in any discipline concerned with nonlinear phenomena (physics, mathematics, chemistry, geology, economy, etc.), this work provides a wealth of information for teachers and researchers in these various fields. Chaouqi Misbah is a senior researcher at the CNRS (National Centre of Scientific Research in France). His work spans from pattern formation in nonlinear science to complex fluids and biophysics. In 2002 he received a major award from the French Academy of Science for his achievements and in 2003 Grenoble University honoured him with a gold medal. Leader of a group of around 40 scientists, he is a member of the editorial board of the French Academy of Science since 2013 and also holds numerous national and international responsibilities.
