The increasing number of Chinese sensor types used for terrestrial remote sensing has necessitated an additional effort to evaluate and standardize the data they acquire. In this study, we assessed the potential use of GF-1 WFV (Wild Field Camera), ZY-3 MUX (Multispectral camera), and HJ-1 CCD (Charge Coupled Device) sensor data for grassland monitoring by comparing spectral field measurements,...

A recursive attack is presented that is applicable to synchronous stream ciphers consisting of a finite state machine with a linear state-transition function and a multiplexer as output function. A variant of this attack can be used to build a cheap system that bypasses on-line the scrambling of video signals as advised in [1] . 1 The Attacked System The scrambler can be described by a finite s...

Rapid progress in the field of nanotechnology includes using quantum dot-cellular automata (QCA) as a replacement for conventional transistor-based complementary metal oxide semiconductor (CMOS) circuits construction nano-circuits. Due to ultra low thermal dissipation, rapid clocking, and extremely high density, QCA is rapidly growing nanotechnological inhibit effect transistor (FET)-based circ...

Introduction: Polarisation division multiplexing (Pol-Mux) is an important method to improve spectral efficiency in lightwave communications. For Pol-Mux used in ultra-high-capacity fibre systems, polarisation mode dispersion (PMD) [1] not only distorts and broadens the signal, but also couples polarisation-multiplexed channels. In the case of large PMD, this coupling becomes strongly frequency...

A novel one-directional pass-through array for the computation of integer greatest common divisor is designed and implemented on Atmel FPGA. The design is based on the plus-minus GCD algorithm and works in LSB pipelined manner. In contrast with previous designs, the length of the new array is independent of the length of the operands: arbitrary long integers can be processed in multiple passes....

In this paper, we present a study on three-terminal ballistic junction and their applications to rectifiers and MUX/DEMUX. Rectifying effect is observed up to 94 GHz at room temperature. Although THz frequency performance has been demonstrated by Monte Carlo simulation, the high impedance of the nano-device combined with the parasitic capacitances is a limiting factor. © 2006 Published by Elsev...

We provide feasibility study of building a 1 Tb/s (16×4.375 Gbaud) Pol-Mux 256-QAM, 10 km link using WDM and OTDM. WDM meets the SNR requirement, but OTDM does not and has to reduce tributary count. © 2013 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (060.4080) Modulation; (060.4230) Multiplexing

Application of quantum-dot cellular automata (QCA) technology as an alternative to CMOS technology on the nanoscale has a promising future; QCA is an interesting technology for building memory. The proposed design and simulation of a new memory cell structure based on QCA with a minimum delay, area, and complexity is presented to implement a static random access memory (SRAM). This paper presen...
