What Is the Meaning of Imaginery Number with Nucleotide Bases as Regards to Quantum Perspective Model?

Tahir Olmez
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 “exi = cos(x) i·sin(x)”. Secondly, twin pi is substituted for x(x = 2Π). Thirdly, the result of this process equals to “e2iπ = cos(2Π) i·sin(2Π)”. Fourthly, sort up this formula just like as in here: “e2iπ = 1 i0” = 1. Fifthly, multiply both sides of th...

Reducing Losses in the Sudanese Power Transmission System 66 kV Sector

Ekram Osman, Mujahid Ahmed, Sufyan Al-Sadiq Suleiman Ibrahim, Helal Qahtan
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. ...

Minimizing Transmission Line Power Losses in Port Harcourt, Southern Nigeria: An Optimization-Based Approach

Ngang Bassey Ngang, Fidelis Ikechukwu Onah, Anthony Lordson Amana, Anthony N. Nzeako
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...

Piezoelectric Model of Water Drop Low Voltage Harvester

Azrul Mahfurdz, Saifuddin Semail, Sunardi Sasmowiyono
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 ...

One-Dimensional Convolutional Neural Network Based Bearing Fault Diagnosis

Jiaxue Chen, Xiaoqi Yin, Chenxue Li, Hang Yang, Li Hong
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...

Optimal Speed Control and Regulation of Salient Pole Hydro Turbine Generators in Nigeria: Artificial Intelligence Approach

Ngang Bassey Ngang, Ezekiel Nnamere Aneke
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 ...

Multi-Channel Low-Noise Analog Front Design

Bin Bai
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...

Summary of Application of Vehicle Radiation Environmental Monitoring System

Jiawen Fan, Jie Xu, Xuan Qin
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...
