Research objectives: Studying and evaluation of active queue management mechanisms to find out the advantages and disadvantages of each mechanism, in order to classify and evaluate application performance for mechanisms and using fuzzy logic to improve active queue management mechanism; the results of the first goals is to perform study motivation first and will be the foundation for the theory and simulation improvements of the thesis.
Over the course of roughly a year, after completing my first book, I resurrected an old
pet project of building an autonomous submarine (referred to as the E-2 project) with
certain fairly challenging functionality requirements. In the course of developing this
idea, I spent many hours on the Internet and elsewhere, researching techniques for
rapid development of various electromechanical control systems and platforms to run
fairly complex signal-processing algorithms.
Soils are aggregates of mineral particles, and together with air and/or water
in the void spaces, they form three-phase systems. A large portion of the
earth’s surface is covered by soils, and they are widely used as construction
and foundation materials. Soil mechanics is the branch of engineering that
deals with the engineering properties of soils and their behavior under
Bearings (both plain and rolling element) are used as important supporting elements for locating rotating components and confining their motion in desired direction. In order to ensure their operational reliability and desired life, these need to be properly designed/selected for an application more so because of ever increasing operational speeds. This requires the careful performance evaluation of different types of bearings considering aspects such as thermal stability, lubrication, contaminants in lubricants and controlling mechanism etc....

Organization scholars have long acknowledged that control processes
are integral to the way in which organizations function. While control
theory research spans many decades and draws on several rich traditions,
theoretical limitations have kept it from generating consistent and interpretable
empirical findings and from reaching consensus concerning the
nature of key relationships.

This paper describes a system for managing: dialogue in a natural language interface. The proposed approach uses a dialogue manager as the overall control mechanism. The dialogue manager accesses domain independent resources for interpretation, generation and background system access. It also uses information from domain dependent knowledge sources, which are customized for various applications.
A modern motion control system typically consists of a motion controller, a motor drive or amplifier, an electric motor, and feed- back sensors. The system might also contain other components such as one or more belt-, ballscrew-, or leadscrew-driven linear guides or axis stages.

The mechatronic servo system is the major theme studied in this book. In
particular, the servo system adopted in an electric servo motor is explained in
this chapter. Several items of its utilization from the development stage to the
present as well as its performances. The so-called mechanism machine (called
as mechatronic servo system at the following), i.e.

Motion control systems today can be found in such diverse applications as materials handling equipment, machine tool centers, chemical and pharmaceutical process lines, inspection stations, robots, and injection molding machines.
Merits of Electric Systems
Most motion control systems today are powered by electric motors rather than hydraulic or pneumatic motors or actuators because of the many benefits they offer: • More precise load or tool positioning, resulting in fewer product or process defects and lower material costs.
Engineers use the concepts and methods of mechanics of solids in designing and evaluating tools, machines, and structures, ranging from wrenches to cars to spacecraft. The required educational back ground for these includes courses in statics, dynamics, mechanics of materials, and related subjects.
Since the foundation and up to the current state-of-the-art in control engineering, the
problems of PID control steadily attract great attention of numerous researchers and
remain inexhaustible source of new ideas for process of control system design and
industrial applications. PID control effectiveness is usually caused by the nature of
dynamical processes, conditioned that the majority of the industrial dynamical
processes are well described by simple dynamic model of the first or second order....
