Object Oriented Web Software Maintainability
using Fuzzy Logic
Shreesh Raj*
Department of Software Engineering, Gautam Buddha University, Greater Noida, Uttar Pradesh, India
Abstract
In the software development lifecycle, maintenance is the most costly activity because it
requires more effort compared to other activities. Maintainability is considered as important
factor for development of good quality software. Nowadays web application is very complex
and hard to maintain. In order to estimate the maintainability of object oriented web
application, this paper uses some quantitative metrics for predicting maintainability of object
oriented web application. Maintainability can be estimated by some quantitative metrics. In
this paper, some object oriented metrics and web application metrics are used to estimate the
maintainability. In order to estimate the maintainability paper considered a real object
oriented web application, which is made on.net Framework4, C# Programming Language..net
is also an object oriented programming language. A maintainability model is proposed using
the fuzzy logic.
Keywords: Web application, Object oriented metrics, Web metrics, Maintainability (M),
Depth of inheritance (DIT), Lines of code (LOC)
INTRODUCTION
Software maintainability can be defined as
“The change in software to fix the error and to
enhance the performance and quality of the
software products”. For the entire life cycle of
software products, the factor maintainability is
one of the most important quality
characteristics [1]. This Research paper is
estimating the maintainability of the object
oriented web application. Web applications are
those which run on a web server, in which user
can access the web application with the help of
a web browser. In this era, web application is
being made by some advance programming
language like C#. It is very difficult to
estimate the maintainability of the web
application. There are various ways to estimate
the maintainability. Many studies show that a
strong relationship between object oriented
metrics and software maintainability. Many
object oriented metrics has been proposed.
Paper estimates the maintainability using some
metrics. Many metrics have been proposed by
various researchers to estimate the
maintainability of software. Paper uses both
object oriented metrics and web metrics to
estimate the maintainability of the object
oriented web software. Research paper
included the object oriented metrics like Line
of Code, Class Complexity, Class Coupling,
Depth of Inheritance and Web Metrics Size,
Structural Complexity, Control Coupling, Data
Coupling, Reusability. Web applications are
required to be maintained due to some features
of web applications like heterogeneity,
dynamic nature. The main aim of this paper is
to estimate the maintainability on the basis of
the metrics discussed above. Paper proposes a
fuzzy model to estimate the maintainability of
object oriented web application.
RELATED WORK
Software maintenance is an important part of a
software life cycle. It is the last phase of
software lifecycle. It can consume as much as
90% of the total effort expended on a system
in its lifetime. It has been widely studied by
many researchers. The maintainability of
object oriented software can be measured
using different metrics. Many researchers used
object oriented metrics to estimate the
maintainability of the object oriented software.
Proposed a maintainability model using object
oriented metrics and compared the software
made on different programming languages.
Researchers found C++ programming language

Deep-Web Interfaces
Raju Dara, Saikiran*
Department of Computer Science Engineering, Krishna Murthy Institute of Technology and
Engineering, Jawaharlal Nehru Technological University, Hyderabad, Telangana, India
Abstract
Deep web is growing faster which is generally hidden. The discovery of deep web can provide
more information about web applications. Due to the dynamic nature of web applications and
large volume of the web resources, it is not easy to locate deep-web interfaces. In this paper
we propose a crawler to discover deep web interface. We designed and implemented the
crawler using a prototype application in Java platform. The crawler is responsible to obtain
details of deep web interfaces. We used the concept of pre and post query forms in order to
have accurate classification of forms. We proposed an algorithm to make use of pre and post
query forms to discovery deep web interfaces. Our empirical results revealed that the
proposed algorithm is useful to discover hidden interfaces from deep web.
Keywords: Crawler, deep-web interfaces, pre-query form, post-query form
INTRODUCTION
Internet has become an essential platform for
running web sites and web applications. The
informative and interactive applications are
running over World Wide Web to serve people
across the globe. The usage of web
applications is becoming more and more with
dynamic web applications used by
organizations. Such web applications might be
hidden and this paper throws light into the
discovery of web interfaces generally not
shown. Deep web refers to the web content
which is behind searchable web interfaces.
The web applications in the Internet are
dynamic in nature and they are made up of
plethora of web resources. The web resources
are hidden in the deep web that need to be
discovered. In this paper we proposed an
algorithm that is used to explore pre-query and
post-query concept in order to discover deep
web interfaces effectively. We built a
prototype application to demonstrate the proof
of concept. The empirical results are
encouraging. The remainder of the paper is
structured as follows: Next section provides
review of literature. Subsequent sections
present the proposed system in detail and
experimental results while last section
concludes the paper.
RELATED WORKS
There are many techniques in the real world
for understanding deep web as explored in
Ref. [1–5]. There are many hidden web
crawlers that are used to discover web
interfaces hidden in WWW [6–8]. There are
deep web samplers that are applications to
model deep web interfaces [9–11]. For all
applications of this kind it is very challenging
to discover content from deep web. Locating
web content there are approaches that are
explored in Ref. [12]. Google index is
associated with sampling of web pages around
25 million. Generic crawlers are able to crawl
all kinds of content over web. However, they
are not sufficient to have deep web interfaces.
Later on researches explored using special
crawlers in order to discover deep web
interfaces [13–20]. In this paper we proposed
an algorithm that can be used by web crawler
in order to have flexible deep web interface
search using pre-query and post-query forms.
PROPOSED SYSTEM
We proposed an algorithm for deep web
exploration. The proposed algorithm can take
deep web forms of post query and pre-query as
inputs and performs crawling in order to obtain
improved accuracy in classification of web
forms discovered from deep web (Algorithm 1).

Cooperation Based Mechanism to Contrast Black
Hole Attack in DTN
Karishma, Nidhi
Department of Computer Science and Applications, Kurukshetra University,
Kurukshetra, Haryana, India
Abstract
Delay tolerant network (DTN) has intermittent node connectivity and nodes are highly mobile.
Most often DTN behaves abnormally due to the presence of various malicious nodes and
because of challenging environment they try to gain the benefit of presenting itself as a
normal node. In this thesis, we focused on black hole attack. A black hole node silently
removes or drops the packets without acknowledging the source and destination. When black
holes are presented in networks, then message drop rate increases, also message delay
increases. To identify or detect black hole attack, we propose a cooperation based mechanism
that uses concept of CTV (Collective Trust Value). The proposed mechanism has been
implemented on ONE simulator with different performance metrics and compared with
existing technique.
Keywords: DTN (Delay Tolerant Network), black hole, CTV (Collective Trust Value),
cooperation, ONE (Opportunistic Network Environment)
INTRODUCTION
Delay tolerant network is a system that is
getting growing interest in network research
community [1]. Delay tolerant networking is a
very promising technology for realizing the
ubiquitous vision. Based on the increasing
pervasiveness of our world, and on realizing
end-to-end connectivity constraint, it can
better exploit social characteristics via context
awareness. We have investigated some of the
important aspects of delay tolerance networks
and demonstrated how network performance
can be improved with shortest path map based
mobility model [2]. If two nodes in a DTN
want to communicate, they do so by using the
concept of store-carry-and-forward technique.
Most often DTN behaves abnormally due to
the presence of various malicious nodes and
because of challenging environment they try to
gain the benefit of presenting itself as a normal
node [3]. One malicious node is ‘Black Hole
node’ which silently removes or drops the
packets without acknowledging the source and
destination [4, 5].
RELATED WORK
Surana et al. proposed a watchdog mechanism
[6]. Watchdog mechanisms used promiscuous
mode to detect a malicious node during route
determination phase and provided an alternate
route.
Nath et al. proposed a cluster-based scheme
which was called black hole attack prevention
system in clustered MANET (BHAPSC)
which explored the existence of malicious
nodes and discovered their exact position at
specific time [7]. It maintained a friendship
table for checking relationship of cluster head
with its neighbor node.
Gupta et al. proposed a novel cooperative faith
based strategy to combat selfish and black hole
attacks in DTN supporting architecture of a
post disaster scenario [8]. The CFV calculation
incorporated the cooperation from other
neighboring nodes to arrive at a decision to
forward a message or not. This approach was
quite efficient in DTN because of its
dynamically changing connections and
inability to support central control. Author
strategy incurred a negligible overhead on the
network while providing good benefits in
terms of improved delivery ratio and decreased
latency. It also reduced unwanted packet
drops.

Design of a Technique to Improve Software Maintenance
Using Fuzzy Logic
Shreesh Raj*, Ritesh Kumar
Department of Software Engineering, Gautam Buddha University, Greater Noida, Uttar Pradesh, India
Abstract
Maintainability is one of the most important aspects of software development. In that,
maintenance costs account for at least 60–65% of total software lifetime costs. Software
quality is the most important factor in the development of any software, which can depend on
many quality attributes. Fuzzy logic is one of the techniques, which can be used to establish
the relationship between object oriented metrics and software maintainability. In this paper
we discuss the estimation of software maintainability using fuzzy logic. In this paper, we
proposed a new model using fuzzy inference system for finding the performance of software
maintenance. We have used six different object oriented metrics i.e. adaptability (AD),
complexity (CLX), understandability (USD), document quality (DocQ), readability (RD) and
modifiability (MDY) for accessing software maintainability levels using fuzzy logic. We take
triangular membership function defined in fuzzy inference system in MATLAB for these
metrics in order to predict better software maintainability.
Keywords: Fuzzy logic, fuzzy inference system, complexity (CLX), adaptability (AD),

INTRODUCTION
Software maintenance and maintainability is
defined by many research scholars in their
respective paper, but the most accepted
standard objective of maintenance is given by
IEEE. According to IEEE, standard definition
of maintenance is “the process of changing a
software system or component after delivery,
to correct bugs, enhance efficiency or other
factors, or suitable to a new environment [1].
It can be redefined as “Maintainability of
software is the degree, to which it can be
corrected, understood, adapted and/or
enhanced [2]. Correcting the defect is the most
crucial segment in maintenance of software.
Software maintenance is the most important
part in software engineering, and software
maintenance is divided into four areas:
Adaptive Maintenance
It is the maintenance where modification is
supposed to be done after the delivery of
software product to keep a software product
usable in the new environment.
Corrective Maintenance
It is the maintenance where main objective is
to identify, isolate, and repair a faulty
equipment, machine, or system can be restored
to a working condition.
Perfective Maintenance
It is also done after the delivery of software to
improve the efficiency, maintainability, or
performance of software component.
Preventive Maintenance
It aims to address the problems, which are not
noteworthy at that time but play a major
problem in future.
RELATED WORK
Software maintenance is most important part
of software development life cycle. It means
any modifications and updations is supposed
to be done after the delivery of software
product. A lot of various models are given by
different researchers for the better
maintainability of software product. Pratap et
al. proposed a model for predicting software
maintainability, which works on five different

A new software for examine Interior
Sculpture
One of a Student from University of Granada
(UGR) developed a software that adjust
current medical innovation to investigate the
inside of models. It's a device to see the inside
without harming wood carvings, and it has
been intended for the reclamation and
protection of the sculptural legacy. Francisco
Javier Melero, educator of Languages and
Computer Systems at the University of
Granada and executive of the venture, says
that the new programming rearranges
therapeutic innovation and adjusts it to the
necessities of restorers working with wood
carvings. The product, called 3DCurator, has a
specific viewfinder that utilizes figured
tomography in the field of rebuilding and
protection of sculptural legacy. It adjusts the
medicinal CT to rebuilding and it shows the 3-
D picture of the cutting with which it will
work.
Substituting the customary X-beams for this
framework permits restorers to look at the
inside of a statue without the issue of covering
data displayed by more seasoned methods, and
uncovers its inner structure, the age of the
wood from which it was made, and
conceivable augmentations.
The product that does this task has been
streamlined keeping in mind the end goal to
permit any restorer to effectively utilize it.
You can even modify a few capacities, and it
permits the restorers to utilize the most recent
therapeutic innovation used to study
pathologies and apply it to helpful procedures
of wood models, says teacher Melero. This
framework, which can be downloaded for
nothing from www.3dcurator.es, imagines the
shrouded data of a cutting, confirms in the
event that it contains metallic components,
distinguishes issues of xylophages like
termites and the passage they make, and
identifies new mortars or polychrome works of
art included later, particularly on the first
wraps up.
The principle engineer of 3DCurator was
Francisco Javier Bolívar, who focused on that
the instrument will mean a striking leap
forward in the field of protection and
rebuilding of social resources and the
examination of show-stoppers by specialists in
Art History. Educator Melero clarifies this
new instrument has as of now been utilized to
look at two models claimed by the University
of Granada: the statues of San Juan
Evangelista, from the sixteenth century, and an
Immaculate from the seventeenth century,
which can be practically inspected at the
Virtual Heritage Site Of the Andalusian
Universities.
Flying Car: Dream Comes True
George Jetson hold his entire attention to make
a car for his kids that can fly also, even people
also dream about that car because it will help
to clear the traffic problem. Inventors and
entrepreneurs have been tried to make this
kind of car a while ago but dropped the idea of
this fantasy because of the failure.
Many companies in the whole world including
some aircrafts creator create an air car by
which it is easy to overcome form the crowded
area. A few cars have a technique to unfold
their wings for flying but they were not able to
give this facility to all the cars. Usually they
first take off and arrive vertically like a
chopper. They have many small rotors in place
of a single large one. Each rotor is operated by
a battery-powered electric engine instead of
aircraft engine. There is no surety that flying-
auto dreams will transform into reality. There
are numerous deterrents, including persuading
controllers that the air ship are protected,
making sense of how to deal with a large
number of extraordinary failure flying air ship
over urban communities without impacts and
creating batteries that will keep them overtop
sufficiently long to be valuable.
Business people are pushing ahead. They see a
boundless potential market for air taxis and
claimed little air ship to transport individuals
