Quantifying historical trends in tropical cyclone activity has proved difficult, but a new reconstruction reveals clear global decline over the past century, driven by an increasingly cyclone-hostile environment troposphere.
Objectives: There are two sub systems of paraspinal muscles, the global-mobilizing system and the local stabilizing system. The multifidus muscles are assigned to the local system and stabilize the joints. In contrast, the longissimus muscles are assigned to the global system and force exertion. This study aimed to investigate the median frequency changes in mobilizing and stabilizing muscles f...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
In sessile organisms such as plants, interac aspects like frequency dependence are m probabilistic cellular automata models, we inv petition influenced whether two species could domly placed on a grid and allowed to interac For four different frequency-dependent scen parameter range the two species could coexis tions and the mean-field approximation indica in the explicit spatial simulation. ] ...
Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...
abstract global financial crisis has created too many problems in relations among governments. among these problems, the issue of global monetary management, more than every time in the past four decades, has been moved in the center of international economic attentions. a problem which is specially known with the monetary hostility between united states and public republic of china. where ar...
Internet of Things, also known as the sensor network, refers to the combination of the network formed by a variety of sensing devices, such as radio frequency identification devices, infrared sensors, global positioning systems, laser scanners and other devices with Internet. ZigBee technology is an emerging short-range, low-rate wireless network technology; it is a cross between technology and...
