This paper presents an evaluation of the ocean wave regime impacting the areas of Cua Dai estuary by using the model of MIKE21SW. The purpose of this study is to fully interprete the role of dynamical factor, ocean wave in erosion-accretion processes. The results showed a convergence of ocean waves at the estuary of Cua Dai although it is obstructed by the Cu Lao Cham island in front of the Cua Dai estuary. The northeast and north-northeast waves are mainly prevailing with the frequency of more than 60% in the year.

Formation of the Caucasian floristic complexes remains as a main problem up today. After the status of the west region of the especially protected natural areas of Azerbaijan have been changed in the state level. For the first time there has been made the inventory of the flora of the Geygel National Park, EldarPinery, Garayazy, Korchay State Natural Reservations. At the result there have been determined 107 families, 467 genera and 1200 species.

White-light coronagraphic images of Coronal Mass Ejections (CMEs) observed by SOHO/LASCO C2 have been used to estimate the density jump along the whole front of two CME-driven shocks. The two events are different in that the first one was a ‘‘radio-loud’’ fast CME, while the second one was a ‘‘radio quiet’’ slow CME. From the compression ratios inferred along the shock fronts, we estimated the Alfve´n Mach numbers for the general case of an oblique shock.

The article is devoted to Circle covering problem for a bounded set in a two- dimensional metric space with a given amount of circles. Here we focus on a more complex problem of constructing reserve and multiply coverings. Besides that, we consider the case where covering set is a multiply-connected domain. The numerical algorithms based on fundamental physical principles, established by Fermat and Huygens, is suggested and implemented. It allows us to solve the problems for the cases of non-convex sets and non-Euclidean metrics.

Shock wave–boundary-layer interactions(SBLIs) occur when a shock wave and a boundary layer converge and, since both can be found in almost every supersonic flow, these interactions are commonplace. The most obvious way for them to arise is for an externally generated shock wave to impinge onto a surface on which there is a boundary layer.

Over many years, RF-MEMS have been a hot topic in research at the technology and device level. In particular, various kinds of mechanical Si-MEMS resonators and piezoelectric BAW (bulk acoustic wave) resonators have been developed. The BAW technology has made its way to commercial products for passive RF filters, in particular for duplexers in RF transceiver front ends for cellular communications. Beyond their use in filters, micromachined resonators can also be used in conjunction with active devices in innovative circuits and architectures.

Chester Pelton retracted his paunch as far as the breakfast seat would permit; the table, its advent preceded by a collection of mouth-watering aromas, slid noiselessly out of the pantry and clicked into place in front of him. "Everything all right, Miss Claire?" a voice floated out after it from beyond. "Anything else you want?" "Everything's just fine, Mrs. Harris," Claire replied. "I suppose Mr. Pelton'll want seconds, and Ray'll probably want thirds and fourths of everything.

John sauntered lazily towards his new high school, making his parents wait as long as possible in their stupid H-cell car. He hoped that he was pissing them off. Their idea to send him to this hi-tech educational prison, their idea to wait out front until he synced on the school grounds, both because they didn’t trust him. So screw them. He glanced back over his shoulder, saw their fake big smiles and waving arms, waving him on. Shit, how humiliating. Ahead at the main entrance, the view held more promise. Two perfect girls, lush hair, blemishless skin, full lips, sculpted curves.

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.

Fibre Optic Thermometers Properties of Optical Fibres Dielectric opticalfibre, which is also referred to as a light guide, is composed of a rod core surrounded by a sheath as shown in Figure 6.1 . The core, which conducts the electromagnetic wave, has a refractive index, nj , while the sheath, which contains the wave within the core, has a refractive index, n2 . To ensure that the wave is contained in the core it is necessary that the condition nj n2 is satisfied. The electromagnetic waves incident on the front part of the optical fibre, within the angle cone, 2a,...

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.
