The one-way (transmitter to receiver) radar equation is derived in this section. This equation is most commonly used in
RWR or ESM type of applications. The following is a summary of the important equations explored in this section:
This book will teach you how to bring together what you know
of finance, accounting, and the spreadsheet to give you a new

finance today. It’s an expertise that will stand you in good stea
in any arena—Wall Street or Main Street—where numbers ar
important. Whether you are a veteran, just starting out on you
career, or still in school, having this expertise can give you
competitive advantage in what you want to do....
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.
This book grew out of the notes of the course on quantum ﬁeld theory
that I give at the University of Geneva, for students in the fourth year.
Most courses on quantum ﬁeld theory focus on teaching the student
how to compute cross-sections and decay rates in particle physics. This
is, and will remain, an important part of the preparation of a high-
energy physicist. However, the importance and the beauty of modern
quantum ﬁeld theory resides also in the great power and variety of its
methods and ideas.
Sales promotions can be seen as a service that provides encouragement to purchase a product or service by changing
the perceived value-for-money equation. In the past decade manufacturers and retailers have been gradually switching
from above the line mass media advertising to a variety of below the line sales promotions. Although sales promotions
take up a very large share of total marketing expenditure, they remain an area which has less strategic consideration or
attention than any other aspect of the promotion mix, especially in the international market arena.
Partial differential equations (PDEs) are very important in modelling as their solutions
unlock the secrets to a range of important phenomena in engineering and
physics. The PDE known as the wave equation models sound waves, light waves
and water waves. It arises in fields such as acoustics, electromagnetics and fluid
This is a textbook on geometric algebra with applications to physics and serves
also as an introduction to geometric algebra intended for research workers
in physics who are interested in the study of this modern artefact. As it is
extremely useful for all branches of physical science and very important for
the new frontiers of physics, physicists are very much getting interested in
this modern mathematical formalism.
engineering; these methods allow considerable freedom in putting computational elements where you want them, important when dealing with highly irregular geometries. Spectral methods [13-15] are preferred for very regular geometries and smooth functions
ROTHE TIME-DISCRETIZATION METHOD APPLIED TO A QUASILINEAR WAVE EQUATION SUBJECT TO INTEGRAL CONDITIONS
ABDELFATAH BOUZIANI AND NABIL MERAZGA Received 27 January 2004 and in revised form 12 February 2004
This paper presents a well-posedness result for an initial-boundary value problem with only integral conditions over the spatial domain for a one-dimensional quasilinear wave equation. The solution and some of its properties are obtained by means of a suitable application of the Rothe time-discretization method. 1.
This material is taught in the BSc. Mathematics degree programme at the Manchester Metropolitan University, UK. The Finite Volume Method (FVM) is taught after the Finite Difference Method (FDM) where important concepts such as convergence, consistency and stability are presented. The FDM material is contained in the online textbook, ‘Introductory Finite Difference Methods for PDEs’ which is free to download from:
Computers are one of the most important tools in any field of science and
especially in physics. A student in an undergraduate lab will appreciate the
help of a computer in calculating a result from a series of measurements.
The more advanced researcher will use them for tasks like simulating an
experiment, or solving complex systems of equations. Physics is deeply
connected to mathematics and requires a lot of calculational skills. If one is
only interested in a conceptual understanding of the field, or an estimate of
the outcome of an experiment, simple calculus will probably suffice.
The emergence of a new paradigm in science offers vast perspectives for future
investigations, as well as providing fresh insight into existing areas of knowledge,
discovering hitherto unknown relations between them. We can observe
this kind of process in connection with the appearance of the concept of solitons
The Naval Facilities Engineering Command seeks to expand the technology
base upon which future shore facilities are founded. An important
area in which a new design approach is being developed is in the management
and understanding of those characteristics of earthquake and explosively
generated foundation motions that damage or destroy Naval equipment.
This report is a part of the design method development. Specifically,
it documents and offers a new method of shock and response spectrum
Diffusion is the transport of matter from one point to another by thermal
motion of atoms or molecules. It is relatively fast in gases, slow in liquids, and
very slow in solids. Diffusion plays a key rˆole in many processes as diverse as
intermixing of gases and liquids, permeation of atoms or molecules through
membranes, evaporation of liquids, drying of timber, doping silicon wafers to
make semiconductor devices, and transport of thermal neutrons in nuclear
The subject of acoustic waves might easily be considered a mature one, quite
specialized, with narrow and circumscribed fields of interest and of application. The
present book is an evidence of the opposite: it witnesses how the concept of acoustic
wave, a collective displacement of matter which perturbs an equilibrium
configuration, is a pervasive concept, which emerges in very different fields. This type
of phenomena can be analyzed from different points of view, it can be exploited in
different ways, and is the object of active investigations.
The inner magnetosphere is an important region of space plasma because it is one of
the “kitchens” for space weather effects. The scientific understanding of this region
is important for predicting the interaction between space environmental conditions
and human activities.
The inner magnetospheric plasma is a unique composition of different plasma
particles and waves. It covers a huge plasma energy range with spatial and time
variations of many orders of magnitude.
Before and After Radical Prostate Surgery is a research-based, comprehensive, and comprehensible resource on prostate surgery in Canada. Aimed at men with concerns about prostate surgery and their partners, this invaluable guide includes chapters on preparing for prostate surgery, the surgery itself, recovery in hospital and at home, a list of recommended resources, and special sections to record personal notes and important contact information.
This analysis of East Asian corporations allows us to study the subject of earnings
informativeness in a different ownership context from that of the research on U.S.
corporations. Our research results are also rich in policy implications. In general, our
results support Ball, Kothari, and Robin (2000) by finding that policy makers should
consider a country’s overall institutional environment before prescribing a comprehensive
set of rules and regulations for corporate reporting.
From a basic hardware point of view it is important to understand the steady-state equations of a hydraulic and electric actuator. The majority of hydraulic positioning or machine feed drives use a rotary actuator with a servo valve attached to the motor to minimize the amount of trapped oil under compression. By minimizing the volume of oil that is trapped between the servo motor and servo valve, the hydraulic resonance will be increased and the drive made more stable.
