• New Method for the Transient Analysis of Lines with Corona
• Authors: Mohamed Mostafa Saied
Pages: 1 - 9
Abstract: -- A new direct procedure for the transient analysis of overhead lines under corona is suggested.
The governing partial differential equations are derived taking into consideration the possible
variations in the line’s equivalent conductance and capacitance. A noniterative solution of
these equations can be found in terms of interpolating functions resulting from a Mathematica
computer code. The developed program can handle any time waveform of the sources
initiating the transients, any line length, design and termination. The transient voltage and
current distributions as well as the voltage-charge plots for several case studies are presented
and discussed.

• Frequency Characteristics and Transient Response of Transmission Lines
with Longitudinally Varying Ambient Temperature
• Authors: Mohamed Mostafa Saied
Pages: 19 - 30
Abstract: This paper addresses the steady state, the frequency characteristics and the transient response of
power lines in the presence of longitudinally varying ambient temperature. This variation will
lead to location-dependent line circuit parameters and to a changing equivalent circuit. The
derived models, which are based on the exact long line theory, can incorporate the impact of the
different patterns of the temperature distribution in terms of location and magnitude. Several
case studies of the resulting non-uniform lines are investigated. The results include the steadystate
response at any frequency, the transient voltage and current distributions and the line’s

• Bloom Box Powered Electrical Vehicle with Carbon Nanotubes Wound Motor
Drive Train
• Authors: Razib Kumar Ghosh, Mohammad Abdul Mannan
Pages: 31 - 42
Abstract: The electrical energy is the main concern to run of an electrical vehicle. This electrical energy is
generally obtained from a bank of batteries. These batteries require lot of space, and they are
heavier. These facts affect the performance and efficiency of an electrical vehicle. Bloom box
can utilize both fossil (natural gas) and renewable (stream air) sources to produce electricity. Its
operation is noiseless. It can supply higher energy although it is smaller in size. Its size and
weight is m Zore less than batteries which are used in electrical vehicles. So battery can be
replaced by bloom box in the power distribution panel of an electrical vehicle to supply
electricity. In addition, carbon nanotubes offer higher conductivity and thermal stability than
copper. So copper can be replaced by carbon nanotubes based yarn of electrical motor in the
drive trains to reduce energy loss, increase efficiency and reduce size and weight of the motor as
well as whole electrical vehicle. In this paper, the carbon nanotubes assisted motor drive train is
proposed for an electrical vehicle which is powered by bloom box. The performance of proposed
electrical vehicle has been verified using various mathematical calculation and simulation
works. The simulation has been done using COMSOL Multiphysics 5.0 for Bloom Box layout
and Matlab/Simulink model for direct current (DC) series wound type motor.

• Hardware Implementation of IoT-based Health Monitoring of Three-phase
Induction Motor
• Authors: Pranita V Mane
Pages: 43 - 49
Abstract: In this project, a wireless monitoring system for three-phase induction motor is realized using
IoT (internet of things), where wired communication is either more expensive or impossible
due to physical conditions and human hazards for safe and economic data communication in
industrial fields. The parameters such as phase current, speed, vibrations and temperature are
monitored by Raspberry Pi and then send these values on cloud. The aim of this project is to
monitor and acquire the remote electrical parameters like three-phase currents, temperature,
vibration and speed, and send these real values over wireless network. The system is designed
using ACS712 current sensor, DS18B20 temperature sensor, SW-18010P vibration sensor and
Infrared speed sensor. These sensors are interfaced with Raspberry Pi 3 model B+ and send
over the wireless network for monitoring.

• Energy estimations and hypothetical design of an exclusive tourism spot in
coastal region named “Bhasan Char” of Bangladesh.
Pages: 1 - 9
Abstract: Bhasan char is a coastal island at Hatiya upzilla of Noakhali District. It is a single char which has been uncovered from the Bay of Bengal a few years back. An emergency humanitarian project implemented by the government of Bangladesh at this coastal island “Bhasan Char”, from September 2017, to temporarily rehabilitate a portion of incoming Rohingya refugees before they can repatriate to their homeland, Myanmar. Under this project, GoB carries out land development, construction of embankment as well as other infrastructures. Upon repatriation of Rohingya’s to Myanmar, we can use the developed land & surroundings as exclusive tourist zone due to its location from mainland. This paper is a proposal to establish Bhasan Char as an exclusive tourism spot in modular basis as a pilot project. We have carried out a hypothetical design of this spot and also calculated the energy requirement for sustainable operation. We have selected environment friendly green energy to be as a major source of energy. We want pollution level to be very minimum there.
