Textile construction is well known for having a significant effect on the ballistic response of fabrics. One possible mechanism for this effect is the change in yarn-yarn interaction with changes in weave geometry. During an impact event, strain waves propagate through both fill and warp yarns. Energy transfer from warp to fill yarns and fill to warp yarns is a phenomenon that has been largely ...

This paper derives equations that describe level-crossing rates and average fade durations for mobile receivers operating in spatially complicated multipath channels. The results are useful for describing fading statistics for wireless systems that operate in realistic propagation channels or employ smart antennas, adaptive arrays, or other technologies that lead to a non-omnidirectional distri...

This paper presents the MANTRA I machine, an SIMD neuro-computer based on a square systolic array of dedicated processing elements (PEs). A VLSI custom chip, called GENES IV containing 2 2 PEs is at the heart of the system. This machine implements suucient instruction and data ows to keep the array's utilization rate close to 100 %.

This study examined whether the level of cognitive engagement that older adults were willing to invest was disproportionately influenced by the personal implications of their task, as suggested by selective engagement theory. We experimentally altered the personal implications of a task by manipulating participants’ accountability for their performance. Younger (n 50) and older (n 50) adults pe...

A systolic array implementation of a general-purpose inference processor is presented. The proposed processor can be used as a building block in the inference engine of an expert system or in a rule-based controller where computational speed is of importance.

Most fast block-matching motion estimation (BMME) algorithms are designed to minimize the search positions (or checking points) in a given search range in order to speed up the computation. In this paper, we introduce a fast BMME algorithm based on the consideration of hardware implementation. We use a one-dimensional (1-D) systolic array as the basic computing engine. In order to utilize this ...

A new approach to Bayesian reconstruction is proposed that endows the prior probability distribution with an inherent geometrical flexibility, which is achieved through a transformation of the coordinate system of the prior distribution or model into that of the reconstruction. With this warping, prior morphological information regarding the object that is being reconstructed may be adapted to ...

We summarize results from an H I+optical imaging study of the “Integral Sign” galaxy, UGC 3697. UGC 3697 is a low-mass, Sd spiral that exhibits a “superthin” disk morphology despite a prounced gasous and stellar warp. Our new observations show evidence for a recent minor merger in this system that could account for its large-scale warp and a number of other properties of this galaxy. We specula...

Background The tricuspid annular plane systolic excursion (TAPSE), which has been used for over a quarter century as a quick estimate of RV systolic function, was revisited using CMR. It shows good correlation with invasive hemodynamics. MRI is the current gold standard to assess the volumes and anatomy of the heart and we can measure TAPSE more precisely with cardiac MRI to accurately detect a...

Based on the fact that Faddeev’s algorithm can be easily mapped into the Systolic array for implementing. An FPGA implementation of Kalman Filter using Modified Faddeev [1] is proposed The Modified Faddeev uses Neighbor pivoting for triangularization substituting the Gaussian elimination.Gaussion elimination may cause the overflow of the datas, and Neighbor pivoting can guarantee the stability ...
