We present an adaptive filtering method applied to the single sweep event related potentials data. The method is based on time-sequenced version of the typical adaptive signal enhancers. Two different signals are used at the reference input and the results are compared. The evaluation is made using both simulated and real measurement data. It is found that the use of a reference input composed ...
Canopy Gaps in an Upper Mississippi River floodplain plot were measured as part of a songbird nest-site selectivity study. Two methods of measuring floodplain forest canopy gaps were compared. One method used a ground crew to sweep the plot and record spatial and botanical information of canopy gaps > 10 meters in diameter. The second method used 1:15,000 scale color infrared stereoscopic aeria...
The radiated noise of ships involves strong low-frequency line spectrum, which is greatly related with the working states of auxiliary equipment and the rotation of propeller, and then regarded as the important basis in feature extraction of ships. Moreover, the stochastic resonance has special advantages in the extraction of weak signal. Aiming at the multi-frequency components in radiated noi...
In previous studies, the concept of quarter-sweep iteration has been pointed out to accelerate the convergence rate in solving any system of linear equations generated by using approximation equations. Based on the same concept, the essential aim of this paper is to investigate the effectiveness of the Quarter-Sweep Arithmetic Mean (QSAM) method by using the quarter-sweep approximation equation...
Implementations of lifting-line theory predict the lift a finite wing using sheet semi-infinite vortices extending from vortex filament placed along locus aerodynamic centers wing. Prandtl’s classical implementation is restricted to straight wings in flows without side slip. In this Paper, it shown that can be extended swept if, at control points where induced velocity calculated, second deriva...
Introduction Transition-band balanced steady-state free precession (TB-bSSFP) fMRI has been shown promising for mapping brain activation with high resolution and distortionfree images [1]. However, the narrow functional-sensitivity band of transition-band SSFP fMRI leads to serious instability in spatial and temporal field, even with advanced shimming [1-2]. Previous studies have proposed a sli...
Further performance improvement is necessary for resistive random access memory (RRAM) to realize its commercialization. In this work, a novel pulse operation method is proposed to improve the performance of RRAM based on Ti/HfO2/Pt structure. In the DC voltage sweep of the RRAM device, the SET transition is abrupt under positive bias. If current sweep with positive bias is utilized in SET proc...
