Synopsis
:
Conventional energy metering system in developing
country like India
follows manual system which requires lots of travelling, manual calculation of
reading of electrical energy metering. This conventional metering system is
highly person dependent. It doesn’t give any information about energy theft as
well as it is very difficult to use individual energy data for optimization of
electrical energy load management as all the manual data need to enter in to
the system. The proposed automated energy metering system uses GSM/GPRS based
smart energy meter which are able to transmit online electrical consumption to
server periodically. It also provides energy security by providing alarming
system during energy theft which is calculated based on average consumption
load. In this paper the authors are also describing implementation
concept of this system using LabVIEW software.

Synopsis
:
Fire detection systems have become an integral
part of safer homes and work places. But, fire detection systems are not
effectively deployed in industries and fireworks factories, particularly in
south Tamil Nadu. This unawareness and lack of technology have led to several
deaths in the past and in the present. In general, the fire detection systems
that are conventionally used, have some shortcomings such as weakness to noise,
inability to pin-point the fire consumed area and faulty alarming due to the
use of analogue transmission with 4-20mA current lines. This project, “Fire
control and signaling in Fireworks industries using Controller area network”,
presents a network-based approach to deal with this critical application, with
the help of Controller Area Network (CAN) for pin-pointing the area under fire,
determining the extent of spread, extinguishing it by triggering the actuators
and finally to signal the fire station, with the help of GSM (Global System for
Mobile Communications) technology.

Synopsis :
This paper presents a method and design of the harmonic
filters for adjustable speed drives. Power consumption of harmonic drawing load
is an increasing concern for cost conscious facility managers and engineers.
The proposed system has the function of voltage stability, and harmonic
suppression. This work presents a method capable of designing filters to reduce
harmonic distortion and correct the power factor. The optimization process
considers the discrete nature of the size of the element of the filter .The
simulation results of the system have been carried out with MATLAB 10.
Title
: Modelling and
Simulation Study of a Helicopter with an External Slung Load System
Author Name :
K. Thanapalan, F. Zhang
Synopsis
:
This paper
describes the mathematical modelling, analysis and simulation study of a
helicopter with an external slung load system. The primary feature of the
proposed model is the use of a helicopter model that consists of a six-degree
of freedom and combined with a three-dimensional motion load model. Considering
the two models, a mathematical model for a helicopter carrying an external load
is obtained. The combined system model can be used for stability analysis and
controller development to improve flight handling quality and system
performance. Stability analysis of the system was carried out via simulation.
Simulation results revealed that the stability of the helicopter is
significantly reduced due to the presence of an underslung load.

Vasagam , Meenakshi B. Sundaram , Habibullah H. Sait Synopsis :
In our day to
day life, we physically interact with electronic devices is changing through
our technological research. This change has led to recent techniques, including
the development of touch screen technology. In touch screen technology, the
operator is given an other method of how we can interact with a device. This
technology already operates in three distinct ways: resistive systems,
capacitive systems, and infrared systems. This paper will propose, focus and
compare these technologies with a new concept of touch screens which works
using transistors, focusing on the differences in application.
Title: Simulation of P&O
Algorithm MPPT With Output Sensing Direct Control Method Using Cuk Converter
Author
Name: Mukesh Gupta,
Rohit
Jain
Synopsis:
In this paper, the MPPT (Maximum Power Point Tracking)
with resistive load is implemented in MATLAB with output sensing direct control
method using Cuk converter. The simulated system consists of the BP SX 150S
photovoltaic (PV) module, the ideal Cuk converter, the MPPT control, and the
resistive load (6?). The selection of the purturb & observe (P&O)
algorithm permits the use of output sensing control method which eliminates the
input voltage and current sensors. The direct control method adjusts of duty
cycle within the MPP tracking algorithm. The way to adjust the duty cycle is
totally based on the theory of load matching. When the value of Rload matches
with that of Ropt, the maximum power transfer from PV to the load will occur.
These two are, however, independent and rarely matches in practice. The goal of
the MPPT is to match the impedance of load to the optimal impedance of PV.
