Benchmarking an S1MD pyramid with the Abingdon Cross is discussed. Measured results for a simulated pyramid architecture on a CLIP4 processor array are presented, as well as estimates for a hypothetical hardware pyramid built with CLIP4 like processing elements.

Business groups organized by pyramids enable the ultimate shareholders to control a portfolio of firms with less cash requirement. Further, corporate pyramid induces an internal capital market and makes capital transfer more convenient within the pyramid. In China, the state and business groups control a large number of listed firms through pyramidal ownership structure. What role does the corp...

We proposed an intensity-based morphological pyramid image registration algorithm. This approach utilizes the global affine transformation model, also considering radiometric changes between images. With the morphological pyramid structure, Levenberg-Marquardt optimization, and bilinear interpolation, this algorithm can be implemented hierarchically and iteratively with capability of measuring,...

Pyramid networks have long been proposed for parallel processing. However, when the network contains multiple pairs of source and destination nodes, it is often difficult to use the pyramid efficiently since most of the algorithms try to simultaneously use the apex for each pair of nodes. Therefore, there may exist a severe bottleneck in such circumstances. We propose a Least Level Minimal Rout...

Spatial analysis of salient feature points has been shown to be promising in image analysis and classification. In the past, spatial pyramid matching makes use of both of salient feature points and spatial multiresolution blocks to match between images. However, it is shown that different images or blocks can still have similar features using spatial pyramid matching. The analysis and matching ...

The enhanced pyramid graph was recently proposed as an interconnection network model in parallel processing for maximizing regularity in pyramid networks. We prove that there are two edge-disjoint Hamiltonian cycles in the enhanced pyramid networks. This investigation demonstrates its superior property in edge fault tolerance. This result is optimal in the sense that the minimum degree of the g...

A k-nearest neighbor search algorithm for the Pyramid technique is presented. The Pyramid technique divides d-dimensional data space into 2d pyramids. Given a query point q, we initialize the radius of a range query to be the furthest distance of the k candidate nearest neighbors from q in the pyramid which q is in, then examine the rest of the pyramids one by one. After one pyramid is checked,...

This paper presents a study on the performance of transformed domain features in Devnagari digit recognition. In this research the recognition performance is measured from features obtained in direct pixel value, Fourier Transform, Discrete Cosine Transform, Gaussian Pyramid, Laplacian Pyramid, Wavelet Transform and Curvelet Transform using classification schemes: Feed Forward, Function Fitting...

The enhanced surface area of silicon nanotexture is an important metric for solar cell integration as it affects multiple properties including optical reflectance, dopant diffusion, and recombination. Silicon typically characterized by its surface-area-to-projected-area ratio or factor (EAF). However, traditional approaches measuring EAF provide limited statistics, making correlation studies di...
