Fossil Fuels are always considered as environmental pollutants. On the other hand, the political and economic situations highly affect the price of these fuels. Offshore wind and wave, as renewable energy sources, represent the better alternatives for electricity generation. Therefore, it is necessary that wind speeds effectively be estimated due to the absence of field measurements of the wind...

This paper is concerned with the diffraction of an electromagnetic wave by a perfectly conducting half-plane in a homogeneous bi-isotropic medium (asymptotically). Similar analysis in a source-free field is done in S. Asghar and A. Lakhtakia (1994), Planewave diffraction by a perfectly conducting half-plane in a homogeneous bi-isotropic medium. Int. J. Appl. Electromagnetics in materials, 5, (1...

Recent neutron scattering measurements reveal spin and charge ordering in the half-doped nickelate, La3/2Sr1/2NiO4. Many of the features of the magnetic excitations have been explained in terms of the spin waves of diagonal stripes with a magnetic coupling structure which is fourfold symmetric. However, an optical mode dispersing away from the , point was not captured by this theory. We show he...

• In 1960 Kouwenhoven, Jude, and Knickerbocker reported that adequate circulation of the blood could be achieved by means of closed chest cardiac massage. This technique is said to permit the oxygen demands of the myocardium to be satisfied by external means and thereby makes practical the utihzation of transthoracic electric shock for the reversal of ventricular fibrillation. However, Del Guer...

We consider the focusing L2-critical half-wave equation in one space dimension i∂tu = Du− |u|u, where D denotes the first-order fractional derivative. Standard arguments show that there is a critical threshold M∗ > 0 such that all H1/2 solutions with ‖u‖L2 < M∗ extend globally in time, while solutions with ‖u‖L2 > M∗ may develop singularities in finite time. In this paper, we first prove the ex...

In this article, we analyze the dynamic characteristics of head wave in multi-layered half-space media models with high-velocity layer or low-velocity layer, and the model with a continuous transition-zone between the crust and the mantle by using synthetic seismogram. It is concluded that the dynamic characteristics of head wave are sensitive to the thickness and velocity of the high-velocity ...
