This paper presents an algorithm to generate Walsh functions in four different orderings: Hadamard, Harmuth, Paley and strict sequency. By the analysis of the properties and mutual relations among these four orderings, the authors found a unified approach to generate any of the orderings from the primary set of Rademacher functions. By using these properties, the authors developed a programmabl...

We show the architecture and design of a numeric function generator that realizes, at high speed, arithmetic functions, like log x, sin x, 1 x , etc.. This approach is general; different circuits are not needed for different functions. Further, composite functions, like log (sin ( 1 x )) can be realized as easily as individual functions. A tutorial description of the method is presented, follow...

The study of dynamic behaviour of circuits containing one or more energy-storing circuit elements powered by photovoltaic (PV) generator has been an intriguing aspect to the PV module design engineer. A PV module constitutes a special power source that has a transcendental current-voltage relationship. As can be expected this makes the transient response analysis for such circuits far more comp...

Let f be a real differentiable function in an open interval I with one-to-one derivative. We observe that if the Lagrange mean L [ f ] of a generator f is conditionally positively homogeneous, then f must be of the class C∞ and the function g(x) := x f ′ (x)− f (x) , x ∈ I, is also a generator of L [ f ] i.e. that L [g] = L [ f ].We show that this fact and a result on equality of two Lagrange m...

Pseudo-random number generators can bias Monte Carlo simulations of the standard normal probability distribution function with initial seeds selection. Five generator designs were initial-seeded with values from 10000 HEX to 1FFFF HEX , estimates of the mean were calculated for each seed, the distribution of mean estimates was determined for each generator and simulation histories were graphed ...

Pseudorandomness has played a central role in modern cryptography, finding theoretical and practical applications to various fields of computer science. A function that generates pseudorandom strings from shorter but truly random seeds is known as a pseudorandom generator. Our generators are designed to fool languages (or equivalently, Boolean-valued functions). In particular, our generator foo...

This study presents thermodynamic analysis and optimization of single effect LiCl-H2O absorption cooling system. Thermodynamic models are employed in engineering equation solver to compute the optimum performance parameters. In this study, cut off temperature to operate system has been obtained at various operating temperatures. Analysis depicts that on 3.59 % rise in evaporator temperature, th...

An optimal control of Reverse Osmosis (RO) plant is studied in this paper utilizing the auto tuning concept in conjunction with PID controller. A control scheme composing an auto tuning stochastic technique based on an improved Genetic Algorithm (GA) is proposed. For better evaluation of the process in GA, objective function defined newly in sense of root mean square error has been used. Also i...

The function of our new marine hybrid turbocharger, which has a generator on its rotor shaft, is to supply electric power for consumption onboard a ship and to supercharge the ship’s diesel engine. The generator is driven by the turbocharger shaft, which is rotated by exhaust-gas energy; thus, the generator is an exhaust-heat-recovery device, and energy savings can be expected. A high-speed, hi...
