Currently RFID (radio frequency identification) technology is pushing to the market mainly forced by industry. Passive tags in the UHF (ultra high frequency) region are of particular interest e.g. for supply chains, showing a tendency to become state of the art. Passive tags obtain their energy from the readers during communication. The reader has to power the tag by radiating energy at the sam...

Science and industry demand ever more sensitive measurements on ever smaller systems, as exemplified by spintronics, nanoelectromechanical system, and spin-based quantum information processing, where single electronic spin detection poses a grand challenge. Superconducting quantum interference devices SQUIDs have yet to be effectively applied to nanoscale measurements. Here, we show that a simp...

Ultra-wideband (UWB) communication techniques have attracted a great interest in both academia and industry in the past few years for applications in short-range wireless mobile systems. This is due to the potential advantages of UWB transmissions such as low power, high rate, immunity to multipath propagation, less complex transceiver hardware, and low interference. In this paper we review com...

A hybrid-duplex aeronautical communication system (HBD-ACS) consisting of a full-duplex (FD) enabled ground station (GS), and two half-duplex (HD) air-stations (ASs) is proposed as a direct solution to the spectrum crunch faced by the aviation industry. Closed-form outage probability and finite signalto-noise ratio (SNR) diversity gain expressions in aeronautical communications over Rician fadi...

Transnational tobacco companies (TTCs) interfere regularly in policymaking in low- and middle-income countries (LMICs). The WHO Framework Convention for Tobacco Control provides mechanisms and guidance for dealing with TTC interference, but many countries still face 'how to' challenges of implementation. For more than two decades, Thailand's public health community has been developing a system ...

High date rate wireless systems with very small symbol periods usually face unacceptable Inter-Symbol Interference (ISI) originated from multipath propagation and their inherent delay spread. Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier-based technique for mitigating ISI to improve capacity in the wireless system with spectral efficiency (bps/Hz). On the other hand, Multi...

(SQUIDs) Joey Lambert December 8, 2008 Josephson junctions are interesting devices that provide a great deal of physics to research, both experimental and theoretical. The device was first proposed by Brian Josephson in short concise paper in 1962 [1], which predicts a resistance-less supercurrent that passes through the very thin insulating layer in between two macroscopic size superconductors...

the term ‘deteriorated texture’ gives all experts as well as ordinary people almost the sameimpression. despite common points in images, the differences put iran cities in different categories based on deteriorated textures. this classification not only has negative effect on the audience from mental point of view but causes various problems for the experts in determining interference method. f...

The health consequences of tobacco use are well known, but less recognized are the significant environmental impacts of tobacco production and use. The environmental impacts of tobacco include tobacco growing and curing; product manufacturing and distribution; product consumption; and post-consumption waste. The World Health Organization's Framework Convention on Tobacco Control addresses envir...
