Background and Aims: Production of acoustic cavitation by sonication has been recently recommended as a targeted treatment. The experimental results from studies indicate that the activity of cavitation generated by bi- or multi-frequency ultrasound irradiation is higher than that caused by single frequency irradiation. In this study, effects dual (1 MHz and 40 kHz) and single frequency soni...

Permanent GPS networks have been established since the 1980s to support a variety of geodetic applications, ranging from local deformation monitoring to large scale crustal motion measurement. Continuously operating GPS (CGPS) networks, consisting of geodetic-grade, dual-frequency receiver systems, generally support relative positioning to sub-centimetre accuracy, even for baselines up to sever...

In this paper, we analyze the performance of transmitter identification (TxID) technique for advanced television system committee digital television (ATSC DTV) signals. In the ATSC DTV systems, signals are transmitted through the multiple frequency network (MFN) so that the frequency resource is used inefficiently. The TxID technique is employed to implement the single frequency network (SFN) w...

In this paper we present a recurrent neural network model to recognize efficient Decision Making Units(DMUs) in Data Envelopment Analysis(DEA). The proposed neural network model is derived from an unconstrained minimization problem. In theoretical aspect, it is shown that the proposed neural network is stable in the sense of lyapunov and globally convergent. The proposed model has a single-laye...

Background: Estimation of the size of hidden and hard-to-reach sub-populations, such as drug-abusers, is a very important but difficult task. Network scale up (NSU) is one of the indirect size estimation techniques, which relies on the frequency of people belonging to a sub-population of interest among the social network of a random sample of the general population. In this study, we estimated ...

This paper designs a nonlinear space-time equalizer based on B-spline neural network (BSNN) for the singlecarrier high-throughput multiuser frequency-selective multipleinput multiple-output (MIMO) uplink. Specifically, BSNN parametrization of high power amplifiers (NHPAs) at mobile terminals’ transmitters, novel identification scheme is developed to estimate dispersive MIMO uplink channel, whic...

Traditionally, all devices of an ad hoc wireless network uses the same frequency band (or channel) for communication. Quite often, however, multiple channels are available but each device cannot operate on all channels concurrently. In such case, multi-channel MAC protocols enable pairs of devices to communicate on different channels simultaneously to increase network throughput. In this paper,...
