The graphs considered here are finite
undirected without loops or multiple edges with p number of vertices and
q number of edges. Let m and n are positive integers. A subset D of
vertices in a graph G is an n- dominating set if every vertex not in D
is adjacent to at least n vertices in D.

General theory of relativity says that the
frequency shift in electro-magnetic radiation near a gravitating mass
happens in one direction only (Gravitational redshift). There in the
EARLIER [21] paper we saw that Dynamic Universe Model says this
frequency shift happens on both the sides of spectrum.

In these days, though the cement
manufacturing companies have introduced various types of blended cement,
the manufacturing of OPC cannot be stopped especially in southern parts
of India. There is still a need for creating awareness among people
about the use of blended cement. In present study, OPC 43 grade cement
is used to manufacture a concrete mix of...

graph. A vertex v in V(G) is r-strong (r-weak) if ) (deg)(deg u v rr
( ) (deg)(deg u v rr ),f for every u is r-adjacent to v in V(G). A
subset S of V is said to be r-strong(r-weak) if for every vertex in S
is an r-strong(r-weak)vertex in G. A subset S of V is said to be
r-strong, r-weak, r-balanced and r-regular set if every vertex in S is

4,4’-[5-nitrobenzene-1,3-diyl
di-1,3,4-oxadiazole-5,2-diyl] azo dye was synthesized from
4,4'-[5-nitrobenzene-1,3-diyldi-1,3,4-oxadiazole-5,2-diyl]dianiline, by
performing multistep reaction during which the compounds were diazotized
and coupled with different napthols and quinoline moieties. Structures
of newly synthesized compounds were characterized and confirmed by IR,
NMR, Mass, spectral studies. The newly synthesized compounds were

blowfish encryption algorithm are being analyzed and examined to see how
these parameters may affect the performance of the algorithm. The
performance indices here are the security and speed of the algorithm.
This study is applied to different types of data; text, sound and image.
For each case the encryption/decryption key length has been changed and
its effect on the performance was noticed. Moreover, the file size is
changed and its affect on the performance of the...

The major demand for fossil fuels and
their continual depletion and high prices has forced the scientific
community to look for alternate options for power production.
Electricity is needed for the economic growth of the world as a whole
and hence the dependence on fossil fuels for electricity production has a
negative impact on the growth of the industrial sector. This has led to
the development of nuclear energy and renewable energy sources. But
unlike renewable energy nuclear energy is associated with...

Smart City initiative is an attempt to
identify the technologies that can solve problems which cities must
confront, such as poor air quality and health related issues, and hence
create a network of partner cities to share the ideas for future
progress. In this work an issue which is to facilitate smarter cities
through world sensing is discussed. Food safety in rural and urban areas
is a very important topic, as it closely affects the health of
citizens. Recent studies highlight that raw milk contain pathogenic
organisms which could...

Valve motion and timing play a major
role in the proper operation of an engine. This paper deals with a
revolutionary design for replacing the present day poppet valves used in
the inlet and outlet systems of a four stroke internal combustion
engine using a single component for performing both functions. The idea
is to match the movement of the valves to a rotating system such that
the two valves can be replaced by a continuous system whereby timing is
maintained by the rotation of the assembly itself. The main...

The epidemic growth of wireless
technology and mobile services in this epoch is creating a great impact
on our life style. Some early efforts have been taken to utilize these
technologies in surveillance. The purpose of the project was to build a
motion detection AV camera, using simple Passive Infra-Red (PIR)
sensors, micro controller, stepper motor and camera. In this AV Camera
with Bluetooth terminal used which used for surveillance system which
captures the Intruders and alert through the Bluetooth terminal....

A numerical study was undertaken to
study the effect of stream wise devices on the base drag at free stream
velocities of 10, 13 and 16 m/s. A literature survey was conducted to
understand the base flow and the control techniques reported in the
literature. Based on the literature survey, a axisymmetric base was
chosen as a baseline case and different configurations of stream wise
tabs were applied to the baseline case. A two dimensional validation was
carried out and it was observed that the software was able to...

A nozzle refers to a tube or pipe of
usually variable cross-sectional area which is mostly axisymmetric. The
aim of the nozzle is to increase and control the rate of flow, speed,
direction, mass, shape, and the pressure of the stream. To design a
suitable nozzle for UCAV so as to provide minimum deformation and hence
helps to improve the performance and efficiency of the engine. The
modeling is done using solid works and the CFD flow analysis is carried
out and the deformation of the nozzle shapes is calculated..

In any gas turbine design cycle, blade
design is a crucial element which needs maximum attention to meet the
aerodynamic performance, structural safety margins, manufacturing
feasibility, material availability etc. In present day gas turbine
engines, most of the failures occur during engine development test and
in-service, in rotor and stator blades due to fatigue and resonance
failures. To address this issue, an extensive structural dynamic
analysis is carried out to predict the natural frequencies and mode
shapes us....

Airframe structures are developed based
on a semi- monocoque construction. Essentially such a structure has a
stiffened skin as the outer cover of the structure .the skin efficiently
carry tensile stresses but requires stabilization to carry
compression and shear loads. The stiffeners provide this stabilization
.A cut- out in the air frame skin structure many a times is a
necessity .doors and windows, access hole are examples of cut-out
present in the airframe .cut-out are discontinuities in the
various load flow paths....

Speech Recognition and Speech Synthesis
plays an imperative responsibility in Human-Machine Interaction.
Synthesized speeches were extracted from concatenating the
pieces of pre-recorded speech utterances from the database. The
proposed work converts the written text into a phonemic and
syllabic transcription. Consequently, it converts both representations
into modified waveform clips that can be combined together to
fabricate as sound. It attempts to describe the individual variations
that occur bet...

Cryptography and stegnography is the art
of hiding secret information from the hackers. In cryptography, it is
easy to found that the text consist of secret information. However, in
steganogrphy, it is difficult to identify the incidence of hidden
information into it. Even if the inter-mediator or hacker tries to
extract information present in the cover image of stegonoography may
fails to extract the exact information hidden over it. The purpose of
embedding cryptography into steganography is to improve the security of
the information..
