This thesis improves upon the work carried out by Mandhani on decimal sequence watermarking showing that the embedding and decoding algorithms used by Mandhani are not robust. We next specify improvements to these algorithms so that the peak signal to noise ratio (PSNR) is maximized and the distortion introduced in the image due to the embedding is minimized. By exploiting the cross correlation...

This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. The authors suggest agronomic practices, including tillage practices, rotations, and input management options that can ameliorate important constraints and sustainably improv...

In this paper, we have investigated the finite-precision effects on a decoder for turbo codes based on the LogBCJR algorithm. As for the numerical accuracy, we have empirically found that three bits are adequate for representing the decimal fractions of the variables in this algorithm. Furthermore, these variables have different numerical ranges for different signal-to-noise ratios, thus requir...

The practice of rounding statistical results to two decimal places is one of a large number of heuristics followed in the social sciences. In evaluating this heuristic, the authors conducted simulations to investigate the precision of simple correlations. They considered a true correlation of .15 and ran simulations in which the sample sizes were 60, 100, 200, 500, 1,000, 10,000, and 100,000. T...

The accurate calculation of decimal fractions is still a challenge for the binary-coded computations that rely on von Neumann paradigm. Here, we report a kind of memristive abacus based on synaptic Ag-Ge-Se device, in which the memristive long-term potentiation and depression are caused by a chemically driven phase transformation. The growth and the rupture of conductive Ag₂Se dendrites are con...

The latest IBM zSeriest processor, the IBM System z10e processor, provides hardware support for the decimal floating-point (DFP) facility that was introduced on the IBM System z9t processor. The z9t processor implements the facility with a mixture of low-level software and hardware assists. Recently, the IBM POWER6e processor-based System pe 570 server introduced a hardware implementation of th...

Precise and accurate automatic recognition of decimal numbers is essential for many applications. Many methods have been used in the literature for this purpose. In this paper, we implement a simple and yet an efficient shift and scale invariant approach for offline machineprint decimal digit recognition using correlation factor between certain reference images and the image under testing. We s...
