  • 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 years old....

  • 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 elsewhere. 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....

  • 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.

  • 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 measurements.

  • 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...

  • 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)....

  • 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.

  • Although the infinite array techniques of Chapter 7 are excellent for system trades and preliminary design, final design requires a finite array simulation. Direct impedance (admittance) matrix methods were described in Section 7.3.2. These were developed by Oliner and Malech, 1966a; Galindo, 1972; Bailey, 1974; Bailey and Bostian, 1974; Cha and Hsiao, 1974; Steyskal, 1974; Bird, 1979; Luzwick and Harrington, 1982; Clarricoats et al., 1984; Pozar, 1985, 1986; Fukao et al., 1986; Deshpande and Bailey, 1989; Silvestro, 1989; Usoff and Munk, 1994; and others.
