A Numerical Study of Shallow Mixing Development over Flat Surface and Dunes
(TSINGHUA UNIV, 2013)
Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a smooth flat bed and dunes. ...
Terrorist Threats to Energy Critical Infrastructure Technology and Protection Systems
(IOS Press, 2013)
Critical infrastructure is an umbrella term referring to a country's assets that are essential to the nation's security public health and safety economic vitality and way of life. This infrastructure is owned or operated ...
Primary user detection in IEEE 802.15.4a based wireless sensor networks
(2013)
Ultra wideband impulse radio (UWB-IR) technology has been defined in the IEEE 802.15.4a standard for location and ranging applications. In this paper, UWB-IR sensors are considered in wireless sensor networks (WSNs) with ...
MP-SAGE based channel estimation for underwater cooperative OFDM systems
(2013)
In this paper, an efficient ehannel estimation algorithm is proposed fOl' amplify-And-forward (AF) eooperative relay based orthogonal fl'equency division multiplexing (OFDM) system in the presenee of sparse underwater ...
A new technique for OFDM: OFDM-index modulation
(2013)
In this study, a novel scheme called orthogonal frequency division multiplexing with index modulation (OFDMIM) is proposed for frequency selective channels. In this scheme, the information is conveyed not only by only M-Ary ...
