In this study we provide the implementation design and hardware structure for the architecture proposed in the previous paper “Image Enhancement and Surface Roughness with Feature Extraction using DWT” IEEE DoI/10.1049/cp.2011.0464. The proposed architecture has been implemented in Microwind and Tanner for power analysis and characteristic study. The result shows very low power consumption than...

This paper presents a construction of very high-rate low-density parity-check (LDPC) codes based on the incidence matrices of unital designs. Like the projective geometry and oval designs, unital designs exist with incidence matrices which are significantly rank deficient. Thus high-rate LDPC codes with a large number of linearly dependent parity-check equations can be constructed. The LDPC cod...

Fresh surgical specimens and blocks, as listed in Table I, were taken from 60 cases, males and females, ranging in age from 22 to 70 years. Fresh surgical specimens were obtained from St. James' Hospital, London (Dr. G. T. Allen, Mr. N. C. Tanner and Mr. A. M. Desmond). Surgical specimens fixed in formalin for variable lengths of time were collected from St. Mark's Hospital, London (Dr. B. Mors...

The restricted isometry constant (RIC) of a matrix A measures how close to an isometry is the action of A on vectors with few nonzero entries, measured in the 2 norm. Specifically, the upper and lower RICs of a matrix A of size n×N are the maximum and the minimum deviation from unity (one) of the largest and smallest, respectively, square of singular values of all (N k ) matrices formed by taki...

Part I: Traditional psychophysical models and Tanner and Swets' model are critically examined. Some of the weaknesses of these models are found to be eliminable by a more sophisticated analysis in terms of detection theory. Accordingly, psychophysical methods are re-examined, and the two-category forced-choice technique is found to be particularly advantageous on theoretical grounds. Applicatio...

Gallager introduced LDPC codes in 1962, presenting a construction method to randomly allocate bits in a sparse parity-check matrix subject to constraints on the row and column weights. Since then improvements have been made to Gallager’s construction method and some analytic constructions for LDPC codes have recently been presented. However, analytically constructed LDPC codes comprise only a v...

The fully-developed thermal and hydrodynamic steady laminar pipe flow of the SPTT fluid is here investigated for the constant wall temperature boundary condition, assuming constant properties and negligible axial conduction. Two limiting conditions were identified: the solution pertaining to the equilibrium between axial convection and radial conduction of thermal energy, and the solution of th...

This paper presents a semi-systolic architecture for decoding cyclic linear error-correcting codes at high speed. The architecture implements a variant of Tanner's Algorithm B, modified for simpler and faster implementation. The main features of the architecture are low computational complexity, a simple, regular arrangement of cells for easy layout, short critical paths, and a high clock rate....

To solve the power dissipation problem, many researchers have proposed different ideas from the device level to the architectural level and above. However, there is no universal way to avoid tradeoffs between power, delay and area, and thus designers are required to choose appropriate techniques that satisfy application and product needs. This paper represents the simulation of different SRAM c...
