DENOISING METHOD BASED ON SPARSE REPRESENTATION FOR WFT SIGNAL
Affected by external noise and various nature disturbances,Wheel Force Transducer (WFT) signal may be completely submerged, and the sensitivity and the reliability of measurement can be strongly decreased. In this paper, a new wavelet packet denoising method based on sparse representation is proposed to remove the noises from WFT signal. In this method, the problem of recovering the noiseless sign...

DEVELOPMENT AND IMPLEMENTATION OF WIRELESS MULTIGAS CONCENTRATION CLOUD SYSTEM
According to the report “GlobalHealth Risks of 2004” issued byWHO(WorldHealth Organization) in Geneva 2009 (WHO, 2012), the mortality rate of the diseases and cause of death which results from the smoke produced by burning solid fuel is ranked tenth, occupying 3.3% of the global amounts, and the DALYs (Disability Adjusted Life Years) is ranked the ninth, occupying 2.7% of the world. Once the p...

CAPACITY OF DATA COLLECTION IN WIRELESS SENSOR NETWORKS BASED ON MUTUAL INFORMATION AND MMSE ESTIMATION
We investigate the properties of data collection in wireless sensor networks, in terms of both capacity and power allocation strategy. We consider a scenario in which a number of sensors observe a target being estimated at fusion center (FC) using minimum meansquare error (MMSE) estimator. Based on the relationship between mutual information and MMSE (I-MMSE), the capacity of data collection in co...

A SELF-OSCILLATING SYSTEM TO MEASURE THE CONDUCTIVITY AND THE PERMITTIVITY OF LIQUIDS WITHIN A SINGLE TRIANGULAR SIGNAL
We present a methodology and a circuit to extract liquid resistance and capacitance simultaneously from the same output signal using interdigitated sensing electrodes. The principle consists in the generation of a current square wave and its application to the sensor to create a triangular output voltage which contains both the conductivity and permittivity parameters in a single periodic segment....

ON FORMAL AND AUTOMATIC SECURITY VERIFICATION OF WSN TRANSPORT PROTOCOLS
We address the problem of formal and automated security verification of transport protocols for wireless sensor networks (WSN) that may perform cryptographic operations. The verification of this class of protocols is difficult because they typically consist of complex behavioral characteristics, such as real-time, probabilistic, and cryptographic operations. To solve this problem, we propose a pro...

MIMO UNDERWATER ACOUSTIC COMMUNICATIONS IN PORTS AND SHALLOW WATERS AT VERY HIGH FREQUENCY
Hermes is a Single-Input Single-Output (SISO) underwater acoustic modem that achieves very high-bit rate digital communications in ports and shallow waters. Here, the authors study the capability of Hermes to support Multiple-Input-Multiple-Output (MIMO) technology. A least-square channel estimation algorithm is used to evaluate multiple MIMO channel impulse responses at the receiver end. A de...
