The evaluation of electrical load estimation is requisitely of any electrical power system. This manner is needed for system obligation, economical distribution and maintenance time of electrical system. In this paper, we propose electrical load estimation method based on fuzzy inference system which gives accurate results for estimated loads in Iraq (Diyala governorateBaaquba city). And it can assist the electrical generation and distribution system that depends on important parameters (temperature, humidity and the speed of the wind). By considering the parameters temperature, humidity and the speed of the wind. These parameters are applied as inputs to the fuzzy logic control system to obtain the normalize estimated load as output by electing membership functions. It is exceptionally valuable to form a choice by taking into consideration these assessed readings that come to from the proposed FIS that displayed in this paper with precision of 0.969 from the real stack request.

The earthing segments of electrical power systems play an important role in ensuring human safety. A core function of these earthing systems is to maintain reliable operation and ensure safety for personnel and apparatus during fault conditions. Earthing electrodes can be buried in the soil to dissipate lightning and fault currents into the earth and limit the effect of any magnitude of voltage and current generated between different contact points to earth structures that may be occupied by people or sensitive electrical equipment. In order to obtain the best design of an electrical system to protect power system installations and ensure human safety against abnormal conditions, it is useful to clarify the behaviour of earthing systems subjected to variable frequency currents. In this paper, a numerical study is thus implemented to investigate the behaviour of earthing electrodes subjected to variable frequency current using the computational software program HIFREQ/FFTSESCDEGS with a uniform equivalent soil model. The effect of soil resistivity and permittivity on the behaviour of earthing electrodes is thus obtained, and the relationship between the length of earthing electrodes and their earthing responses over a wide range of frequencies from DC up to 1MHz is identified.

Step by step the innovation likewise becomes exceptionally quick and the human makes it. Thus, it is imperative to take care of the people to come, a unique consideration ought to be appeared to them particularly indulges. This paper manages plan and usage of intelligent child support framework which is extraordinary blessing to guardians in this century In this work a baby bed with intelligent system was be designed and implemented . many sensors where be used to monitor the baby behavior . the component of this project consist of a smart camera , moisture sensor , sensitive Dc Motor and WiFi system.

This paper presents the description and analysis of the design and HSPICE-based simulation results of very low-voltages (LVs) power supplies and high-performance specifications CMOS gate-driven (GD) operational amplifier (Op-Amp) circuit. The very LVs CMOS GD Op-Amp circuit designed using 90nm CMOS technology parameters and the folded cascode (FC) technique employed in the differential input stage. The HSPICE simulation results demonstrate that the overall gain is 73.1dB, the unity gain bandwidth is 14.9MHz, the phase margin is , the total power dissipation is 0.91mW, the output voltage swing is from 0.95V to 1V, the common-mode rejection ratio is dB, the equivalent input-referred noise voltage is 50.94  at 1MHz, the positive slew rate is 11.37 , the negative slew rate is 11.39 , the settling time is 137 , the positive power-supply rejection ratio is 74.2dB, and the negative power-supply rejection ratio is 80.1dB. The comparisons of simulation results at 1V and 0.814V power supplies’ voltages of the very LVs CMOS GD Op-Amp circuit demonstrate that the circuit functions with perfect performance specifications, and it is suitable for many considerable applications intended for very LVs CMOS Op-Amp circuits.
