This paper attempts to express imaginary number with chemical nucleotide bases (A T, G, C and U) as regards to Quantum Perspective Model. At first, the exact Euler’s formula was written just like as in here “e xi = cos(x) i·sin(x)”. Secondly, twin pi is substituted for x(x = 2Π). Thirdly, the result of this process equals to “e 2iπ = cos(2Π) i·sin(2Π)”. Fourthly, sort up this formula just like as in here: “e 2iπ = 1 i0” = 1. Fifthly, multiply both sides of th...

Electricity is transmitted from the generating stations to the distribution center and consumers through transmission lines, to ensure that energy reaches consumers in the required form and quality, and losses along transmission lines must be minimized. In this project, losses were analyzed and reduced in the East network sector (66 kV) using a modern compensator Static VAR (Volt-Ampere Reactive) Compensator (SVC) and electrical network simulation in the NEPLAN program to validate its validity. ...

An experimental circuit design method of charge sensitive preamplifier for signal readout of silicon detector is introduced. Firstly, the circuit principle simulation and circuit parameter optimization are realized based on Multisim software. Secondly, the circuit is designed with junction field effect transistors (JFETs) as input stage, constant current source as load and integrated operational amplifier as amplifier stage. Finally, the circuit is applied to match silicon semiconductor detector...

In Nigeria, frequent power outages can be attributed to under frequency, low power factor, overcurrent, overvoltage, and under voltage causes. Improving the quality of electric power supply means improving voltage transients and frequency instability. This epileptic power source could be improved estimating the following parameters: Line losses, the phase values of the voltages at load buses, the real and reactive power of slack buses; optimizing these values to determine active power loss reduc...

This research proposes the low voltage measurement from a piezoelectric transducer. The vibration source is acquired from water drop impact for different distances. A strip chart was used to record voltage signal from piezoelectric at a 100-Hz sampling rate. The voltage for each sample was saved in excel format and analysed in MATLAB software. The voltage generated has been compared with and analysed for three types of piezoelectric transducers from polyvinylidene fluoride type (PVDF). Based on ...

Fault diagnosis based on time-domain signals has become mainstream in recent years. Traditional methods require signal processing to extract fault features before feeding them into a neural network for diagnostic classification, which is a cumbersome process. This paper proposes an adaptive fault diagnosis model based on a one-dimensional convolutional neural network, and the structure and parameters of the model are analyzed and designed in detail. The segmented pre-processed vibration signal i...

This research is being carried out to improve the quality of power supply caused by voltage fluctuations due to unstable hydro turbine generator speeds. A solution based on Fuzzy Logic Control was created to eliminate the problem of epileptic power supply in some parts of Nigeria, which was caused by the slow rotation of the hydro turbines. This is accomplished by creating a membership function to analyze the causes of slow turbine rotation, a membership function to increase turbine rotation, a ...

With the development of digital nuclear pulse processing technology, the requirements for the analog front-end circuit of digital energy spectrometers are getting higher and higher. Not only need to reduce the noise caused by the device as much as possible, but also need to meet the needs of multi-channel data acquisition. This article based on VGA (Variable Gain Amplifier) has designed a multi-channel low-noise analog front-end circuit to meet the functional requirements of the energy spectrome...

The vehicle-borne radiation environmental monitoring system is not restricted by time, location and weather, and in the event of a sudden nuclear accident, it can quickly enter the accident site and monitor the ambient reflectivity level and absorbed air dose rate at the first time. At the same time, the vehicle-borne data communication and processing system is used to transmit the real-time data to the platform of emergency monitoring and dispatching, which provides powerful technical support f...

We buy home appliances every once in a while, and we are adding another Remote controller to our homes, and every device has its own remote control. Thus, the purpose of our work is to control all home devices via the Internet and get rid of using multiple Remote Controls. In this paper, we propose a smart remote controller that can be controlling all home devices and operate them through Internet using the mobile app and it contains a self-learning feature and the ESP8266 is used as a microcont...
