We studied theoretically and experimentally the transformation, attenuation, and setup due to shoaling and breaking of internal waves in a two-layer fluid system on a uniform slope. An image processing technique was used to illustrate 2D instantaneous displacements of density interface. These results were compared with the calculated values by using the method of characteristics, the simple shoaling model with energy dissipation, and the momentum balance equation based on a radiation stress concept.
Visiting a nice lake is like going to a grocery store that
has everything. But what happens if the lake is lacking an
item or two? Maybe one or more lake projects can address
the need. Although this book has several hundred project
ideas, many of them are updated project ideas that have
been previously conducted one way or another. For example,
dredging has been occurring for over 4000 years. Fish
culture, aquatic plant management (using handpulling
techniques), and waste disposal are also thousands of
Modern Spectroscopy has been written to fulfil a need for an up-to-date text on spectroscopy.
It is aimed primarily at a typical undergraduate audience in chemistry, chemical physics, or
physics in the United Kingdom and at undergraduate and graduate student audiences
Spectroscopy covers a very wide area which has been widened further since the mid-
1960s by the development of lasers and such techniques as photoelectron spectroscopy and
other closely related spectroscopies.
The idea of using ultrasonic waves in medical and engineering fields came from
military applications of sound waves in sonar systems. Sokolov, Firestone, Simons,
and several other researchers are among the ones who studied this high frequency
kind of wave in the first half of twentieth century.
Ultrasonic waves are defined as those with frequencies higher than 20 kHz. The
constant development of data acquisition systems and probes seems to work,
removing the upper limit of the wave frequency that can be acquired.
This project explores the development of a multiple input multiple output (MIMO) simulator using ray tracing techniques. This project gives an overview of ray tracing techniques, beamforming, MIMO channel models and MIMO systems. It explains the ability of MIMO systems to offer significant capacity increases over traditional wireless systems, by exploiting the phenomenon of multipath. By modelling high frequency radio waves as travelling along localized linear trajectory paths, they can be approximated as rays, just as in optics....
This book aims to provide information about Fourier transform to those needing to use infrared spectroscopy, by explaining the fundamental aspects of the Fourier transform, and techniques for analyzing infrared data obtained for a wide number of materials. It summarizes the theory, instrumentation, methodology, techniques and application of FTIR spectroscopy, and improves the performance and quality of FTIR spectrophotometers.
Design by Eunny Jang A lace stole, worked in two variants of the ancient “Print O’ The Wave” Shetland lace pattern. Light enough to shiver and float in a draft, this stole can be worn as a sheer, delicate wrap (pictured), or doubled as a short scarf. Knit in cobweb weight yarn and US00 needles for the light wrap shown, or in lace weight and US4 needles for a slightly sturdier, larger shawl.
This paper describes a numerical model for the simulation of near shore wave dynamics and bottom topography change. In this part, the nearshore wave dynamics is simulated by solving the depth integrated Boussinesq approximation equations for nearshore wave transformation together with continuity equation with a Crank‐Nicholson scheme. The wave runup on beaches is simulated by a scheme, similar to the Volume Of Fluid (VOF) technique.
In recent years, great advancements have been made in understanding the mechanisms of the functioning
of the human brain. Technological developments such as functional magnetic resonance
imaging (fMRI), positron emission tomography (PET), and magnetoencephalography (MEG) have
made possible the mapping of the images of cerebral activity from hemodynamic, metabolic or electromagnetic
Many classical integrable systems (like the Euler, Lagrange and
Kowalewski tops or the Neumann system) as well as finite dimensional reductions
of many integrable PDEs share the property of being algebraically
completely integrable systems4. This means that they are completely integrable
Hamiltonian systems in the usual sense and, moreover, their complexified
invariant tori are open subsets of complex Abelian tori on which the
complexified flow is linear. To such systems the powerful algebro-geometrical
techniques may be applied...
Today, the ultrasonic signal is being used for predicting material behavior,
characterizing (detecting internal anomalies in) a variety of engineering structures,
as well as for inspecting human body parts like tumors, bones, and unborn fetuses.
Because of the ever-increasing popularity of the ultrasonic techniques in a wide
range of applications, this technology has received a lot of attention from the
research community. This book presents some new developments in ultrasonic
research for material and structure inspection. Application areas cover both
engineering and biological materials....

Like the dotcom organizations that went bust at the end of the last
century, CRM (Customer Relationship Management) is making a
powerful and dramatic comeback. Today, the most exciting growth
areas of the commerce are being found in the electronic arena. The
same is true of CRM.
In the late 1990s and early years of the 21st century, CRM was
offered up as the next wave of marketing. The tools and techniques
that would make traditional marketing obsolete
The earthquake motion is assigned
classified by Japan's land area is classified into three categories according to level
seismic risk and adjust the seismic motion by using the regional adjustment factor of 1.0, 0.85
and 0.7 depending on the classification of the area.
Meanwhile, the studies to calculate seismic waveforms unique to the target area of seismic
design has been conducted in recent years.
Digital Modulation Techniques
There are three ways in which the bandwidth of the channel carrier may be altered simply. It is worth emphasizing that these methods are chosen because they are practically simple, not because they are theoretically desirable. These are the altering of the amplitude, frequency and phase of the carrier sine wave. These techniques give rise to amplitude-shiftkeying (ASK), frequency-shift-keying (FSK) and phase-shift-keying (PSK), respectively. ASK describes the technique the carrier wave is multiplied by the digital signal f(t)....

During the past decade, several new fabrication techniques have evolved which helped
popularize microelectromechanical systems (MEMS), and numerous novel devices have
been reported in diverse areas of engineering and science. One such area is microwave
and millimeter wave systems. MEMS technology for microwave applications should solve
many intriguing problems of high-frequency technology for wireless communications.
Before entering into the different techniques of optical metrology some basic terms and deﬁnitions have to be established. Optical metrology is about light and therefore we must develop a mathematical description of waves and wave propagation, introducing important terms like wavelength, phase, phase fronts, rays, etc. The treatment is kept as simple as possible, without going into complicated electromagnetic theory.
