In this paper we study a hardware efficient implementation of a uniform random number generator based on Cellular Automata. This random number generator can be used to create Additive Gaussian White Noise and other noise sources in wireless application simulations. The algorithm used to generate random numbers can be realized using simple digital circuits and memory, and we implemented it on an...

Abstract The problem of increasing the efficiency using oncoming air flow for a wind wheel with vertical axis rotation, which is mechanical drive heat generator, considered. It proposed to increase device by installing an aerodynamic shield wheel. Such cylindrical body in generator placed. creates effect confuser, leading speed and, consequently, kinetic energy acting on rotor blades. shown exp...

Microfluidic droplet generators offer distinctive advantages to create emulsions that cannot be matched by conventional methods such as membrane or batch emulsification[1]. Since microfluidic droplets are created in a confined and controlled space in a chip, they can be used as micro-reactors to perform delicate chemical reactions that take advantage of the scaling laws associated with miniatur...

In a recent paper, Richard Crandall and the present author established that each of a certain class of explicitly given real constants, uncountably infinite in number, is bnormal, for an integer b that appears in the formula defining the constant. A b-normal constant is one where every string of m digits appears in the base-b expansion of the constant with limiting frequency b−m. This paper sho...

A characterisation of the generators of quantum stochastic cocy-cles of completely positive (CP) maps is given in terms of the complete dissipa-tivity (CD) of its form-generator. The pseudo-Hilbert dilation of the stochastic form-generator and the pre-Hilbert dilation of the corresponding dissipator is found. The general form of the linear continuous structural maps for the algebra of all bound...

in this paper the effect of block shape vortex generators (vgs) on an air-water fin-tube heat exchanger has been studied experimentally using exergy analysis method. also the effect of these vgs on increasing heat transfer rate has been simulated numerically and the results show a good agreement with the experiments. in this research we used a wind tunnel to produce wind flow over heat exchange...

Geographical conditions Indonesia has natural resources with good potential for the development of renewable energy. One them is wind, wind one in that can be utilized because an archipelagic country a coastline 81000 km. The largest energy are located at sea and near coast. This resource used to generate electricity using turbine, so this research prototype simulate power plant (PLTB). was tes...

This paper presents an autonomous hybrid generation system consisting of wind turbine generators (WTG), a diesel engine generator (DEG), fuel cell (FC), a battery energy storage system (BESS) and an aqua electrolyzer (AE). The generated hydrogen by an aqua electrolyzer is used as fuel for a fuel cell. The power system frequency deviates for the sudden changes in load and generation. The output ...

recently, transverse flux permanent magnet generators (tfpmgs) have been proposed as a possible generator in direct drive variable speed wind turbines due to their unique merits. generally, the quality of output power in these systems is lower than multi stage fixed speed systems, because of removing the gears, so it’s important to design these kinds of generators with low ripple and lowest har...
