Decomposition is performed for the 4×4 SMAP radar channel covariance matrix and the correlation between resulting components, surface soil moisture and vegetation is examined. Globally, the first principal component is the most dominant and the correlation coefficients with respect to soil mortise is highest (R2 ≥ 0.8) in regions with fractional ground cover and sufficient temporal dynamics of soil...
Middle cerebral artery occlusion (MCAO) by intraluminal suture is one of the most commonly used stroke models. Our previous study has indicated that the intraoperative cerebral blood flow (CBF) immediately after the stroke is prognostic for long-term permanent injury. The area of more than 50% CBF drop at the first minute after the stroke was found significantly correlated with the lesion size at...
In this paper, we investigate the relaying issue of Zero-Padding (ZP) Orthogonal Frequency Division Multiplexing (OFDM) technique to estimate Time Difference of Arrival (TDOA) for locationing applications. In order to benefit from the easy processing of Amplify-and-Forward (AF) relay as well as the noise and interference cancellation of Decode-and-Forward (DF) relay schemes, we introduce the trigger...
A fault detection and diagnosis (FDD) method is proposed by combining transfer entropy (TE) and signed digraph (SDG). Given process historical data, transfer entropy is used to construct a SDG model to represent causal relationship between process variables. A fault severity evaluation method is then proposed based on the modified SDG model, where the nodes can take values of (0), (±1), (±3) and (±6)...
Fluctuations in pupil size and lens accommodation are measured concurrently under open loop conditions, constant illumination and far fixation. In 12/17 trials no correlation was measured between the fluctuations in pupil size and lens accommodation. For the remaining 5/17 trials no lag was observed between the changes in pupil size and lens accommodation indicating that this correlation does not...
A new motion estimation algorithm that exploits the motion correlation of neighbor blocks in temporal and spatial directions is presented. Preliminary results indicate that this algorithm achieves significant savings on computation time and the amount of side information on motion vectors.<<ETX>>
