DHCP (Dynamic Host Configuration Protocol) là một giao thức dùng để cấp địa chỉ IP động cho các máy clients. Quá trình xin địa chỉ IP động trải qua 4 bước:
DISCOVERY: Máy client gửi gói tin broadcast trên mạng để tìm kiếm server. DHCP Offer: Khi một DHCP server nhận được gói tin discovery từ client, nó sẽ gửi trả một gói tin DHCP offer. Gói tin này chứa địa chỉ MAC của client, địa chỉ IP dự định cấp cho client, subnet mask, thời gian sử dụng và IP add của DHCP server.
Computational fluid dynamics (CFD) is concerned with the efficient numerical solution of the partial differential equations that describe fluid dynamics. CFD techniques are commonly used in the many areas of engineering where fluid behavior is an important factor. Traditional fields of application include aerospace and automotive design, and more recently, bioengineering and consumer and medical electronics.
With many 'flexible' structures such as large span bridges, tall buildings, towers, cable roofs, etc., being built, the need to understand the dynamics behavior of structures has become a necessity for many engineers. The recent problems with the millinium bridge is simply another reminder. The many devastating earthquakes in many parts of the world leading to severe loss of life in densely inhabited urban areas alos has underlined the need for a fundamental understanding of structural behavior.
This book is intended to serve as a reference text for advanced scientists and research
engineers to solve a variety of fluid flow problems using computational fluid dynamics
(CFD). Each chapter arises from a collection of research papers and discussions contributed
by the practiced experts in the field of fluid mechanics. This material has encompassed a
wide range of CFD applications concerning computational scheme, turbulence modeling
and its simulation, multiphase flow modeling, unsteady-flow computation, and industrial
applications of CFD....
Mechatronics, the synergistic blend of mechanics, electronics, and computer science, has
evolved over the past twenty-five years, leading to a novel stage of engineering design. By
integrating the best design practices with the most advanced technologies, mechatronics aims
at realizing highquality products, guaranteeing, at the same time, a substantial reduction of
time and costs of manufacturing.
This section illustrates some general concepts of artificial neural networks, their
properties, mode of training, static training (feedforward) and dynamic training
(recurrent), training data classification, supervised, semi-supervised and unsupervised
training. Prof. Belic Igor’s chapter that deals with ANN application in modeling,
illustrating two properties of ANN: universality and optimization. Prof.
Optical devices in communication and computation have a significant impact on our daily life, although we may not even be aware of their existence, as in case of inter-continent fiber cables that connect people around the world, making it a global village. Novel nanoscale structures have demonstrated a wide range of unique features; therefore have became a hot research topic. Not only that the novel structural materials are used in biomedical therapy, but also the nature inspires the design of innovative optical structures....
Because of the availability of powerful computational techniques, new modality
techniques such as Computer-Aided Tomography (CAT), Magnetic Resonance
Imaging (MRI) and others, and because of the new techniques of imaging processing
(machine vision), the lives of many patients will be saved, and the quality of
all our lives improved. This marriage of powerful computer technology and medical
imaging has spawned a new and growing generation of young dynamic doctors
who hold PhDs in physics and/or computer science, along with their MDs.
It was in late 1995 to early 1996 (shortly after the birth of his first daughter Claire)
that the author first began to read the currently available finance books in order to
write C/Cþþ financial software. However, apart fromthe book Options Futures and
Other Derivatives by John Hull, he found very little information of practical help and
had to trawl through the original journal articles in the Bodleian library for more
information. Even then much information on how to implement and test various
models was not included.
This book is a practical introduction to scientific computing and offers
BPSIC subroutines, suitable for use on a perscnal complter, for solving a
number of important problems in the areas of chmistry, biology and
pharmacology. Althcugh our text is advanced in its category, we assume only
that you have the normal mathmatical preparation associated with an
undergraduate degree in science, and that you have some familiarity with the
S I C programing language.
The main goal of Grid programming is the study of programming models, tools, and methods that support the effective development of portable and high-performance algorithms and applications on Grid environments. Grid programming will require capabilities and properties beyond that of simple sequential programming or even parallel and distributed programming.
Vector and matrix concepts have proved indispensable in the development of the subject of dynamics. The formulation of the equations of motion using the Newtonian or Lagrangian approach leads to a set of second-order simultaneous differential equations. For convenience, these equations are often expressed in vector and matrix forms. Vector and matrix identities can be utilized to provide much less cumbersome proofs of many of the kinematic and dynamic relationships. In this chapter, the mathematical tools required to understand the development presented in this book are discussed brieﬂy.
Our planet is nowadays continuously monitored by powerful remote sensors operating in wide portions of the electromagnetic spectrum. Our capability of acquiring detailed information on the environment has been revolutionized by revealing its inner structure, morphology and dynamical changes. The way we now observe and study the evolution of the Earth’s status has even radically influenced our perception and conception of the world we live in.
Mechatronics is a design process that includes a combination of mechanical engineering, electrical engineering, telecommunications engineering, control engineering and computer engineering. Mechatronics is a multidisciplinary field of engineering, that is to say, it rejects splitting engineering into separate disciplines.
Dynamic models provide the development team with a detailed picture of the
relationships of use cases and usage scenarios. The models provide current state
descriptions of the workflow processes and important task sequences.
In this activity, you will develop activity, interaction, and state models for the
Ferguson and Bardell, Inc. case study.
