Reliability evaluation of radial distribution system – A
case study
Reliability evaluation of a system or
component or element is very important in order to predict
its availability and other relevant indices. Reliability is
the parameter, which tells about the availability of the
system under proper working conditions for a given period.
In this paper reliability evaluation of an electrical power
distribution system is done and different parameter are
evaluated. The electrical power distribution system taken
for study is radial distribution system in nature.

A Queue Network
M/M/1/∞ Model
In this paper we model an open queueing
network of cardiac treatment section in medical sector.
Assume arrival of patients follows Poisson and service times
at stations have exponential distribution. The performance
measures of the system are evaluated. The steady state
characteristics of the network are obtained and each station
solved independently by using M/M/1/∞ model while blocking
and non-blocking exists. Blocking occurred when at least one
service center has limited queueing space or capacity before
it. An illustrative example is given.

Parametric
Estimation on Constant Stress Partially Accelerated Life
Tests for the Exponentiated Exponential Distribution
using Multiple Censoring
If the items have high reliability then
to check the lifetime of items under normal use condition
takes more time and cost in comparison with the accelerated
condition. The items put higher stress than the usual level
of stresses to generate early failures in a short period to
reduce the costs involved in the testing of items without
any change in the quality. This study is based on constant
stress partially accelerated life tests for Exponentiated
Exponential distribution using multiple censoring schemes.
The maximum likelihood estimates and asymptotic variance and
covariance matrix are obtained. The confidence intervals for
parameters are also constructed. At last, a simulation
technique is used to check the performance of the
estimators.

A Review on
Reusability of Component Based Software Development
People across software community have
marked the true endeavor to go round development of software
through component based software development (CBSD)
practices. Reusability of software component has a very
positive impact on development time, cost, reliability and
marketability of the software. In this paper we are
discussing about bottlenecks of software component
reusability and trying to provide some useful guidelines to
improve the reusability for the component based software
developer which can further improve the productivity, reduce
the development cost. This paper also discusses the steps
for effectively storing the software component in component
repository that is helping the component user in finding the
most eligible component for reuse which will progress the
component based software development.

An Approximation to
Joint System Size Distribution at Nodes in Some Multi-hop
Wireless Networks
In this paper, we discuss a network model to study the
queueing characeristics of nodes in a multi-hop wireless
network, under the standard binary exponential back-off (BEB)
contention resolution scheme. Based on the steady state
distribution of the system size at a node, which was
appeared in Sweta
Deepak [2], we compute the joint
distribution of system size at all nodes in a multi-hop
network, governed by some specific queue disciplines.
Getting information on the joint queuing size distribution
in the network will enable us to control the traffic (and
hence congestion) in the whole network. In order to
illustrate our theoretical results, a particular multi-hop
network model is considered and analysed numerically.

Transient Numerical
Analysis of a Queueing Model with Correlated Reneging,
Balking and Feedback
We consider a single server queuing
model with correlated reneging, balking and feedback. The
time-dependent behavior of the model is studied using
Runge-Kutta method. Some measures of the performance like
expected system size and expected waiting time are computed.
