This paper addresses a novel method to detect and defend against the blackhole attack and cooperative blackhole attack using hybrid DNA-based cryptography (HDC) mechanism. Moreover, the proposed method upsurge the security issue with the underlying AODV routing protocol. Eventually, this HDC is one of the high potential candidates for advanced wireless ad hoc networks, which require less communication bandwidth and memory in comparison with other cryptographic systems. The simulation results of this proposed method provide better security and network performances as compared to existing schemes. © Springer Science+Business Media Singapore 2016. Source

Calculation of deflection in RC slabs is important as the slab thickness depends upon it. Since economy depends upon the thickness of the slab, and hence deflection control, directly affects economical design of the slabs. At present, in different relevant codes clauses are there to control deflection. IS 456-2000 also deal with estimation of short-term and long-term deflections in RC members in general, but there is no particular formula for estimation of short-term and long-term deflections in simply supported two-way RC slab in particular. This paper reviews the methods for estimation of deflections in RC members, suggested by IS 456, and reviews the literature pertaining the same, highlighting need of revision in the codal provisions. The paper gives rational approach for estimating short-term deflection in simply supported two-way RC slabs. The method considers load on the slabs as obtained by Rankin- Grashoffs' methods. The deflection calculated in this way is found to be more accurate as compared to other available methods. The results obtained have been found to be comparable with experimental results available in the literature. The method has been designated as equivalent load method and found to be more realistic for calculating short term deflection of simply supported two way RC slabs. © 2010 CAFET-INNOVA TECHNICAL SOCIETY.

Data from the Pacific network of VLF receivers have been used to study the response of the lower ionosphere to the January 2011 Mt. Kirishima (South Japan) volcanic eruption. A major explosive eruption occurred on January 27, which was preceded by several small eruptions. Perturbations of nighttime subionospheric VLF signals have been detected on the day of the first small eruption on January 18 (UT) with the maximum observed about 1.5. h after the eruption. The nighttime signal remained disturbed during the subsequent pre-eruptive and eruptive activity of Mt. Kirishima. The daytime perturbations were not observed. The frequency of the maximum spectral amplitude was found to be in the range of periods of 6-30. min, which corresponds to the periods of internal gravity waves. These results suggest that the observed VLF ionospheric effects can possibly be produced by the penetration of gravity waves caused by the volcanic activity into the ionosphere. © 2013 Elsevier Ltd.

The modem mini-steel rolling plant due to heavy energy consumption and complicated equipment and highly stressed working conditions requires minimum energy losses during conversion process and its performance control. The Indian steel rolling plant has to match with the competitors, both in-house and abroad in respect to international norms for the environment and pollution and with the energy cost also. An improved model for Pollution emission control and energy optimization of hot rolling process of a mini-steel rolling plant can be obtained by help of Taguchi Loss Function approach.

Short-term (timescale of hours, days and weeks) earthquake (EQ) prediction is of essential importance to mitigate EQ disasters. Short-term EQ prediction has so far been based on seismic measurements (i.e. mechanical observation of crustal movements), but it was concluded in Japan about 10 years ago that EQ prediction is impossible by means of the mechanical method. Hence, there has been an increased interest and a lot of progress in non-seismic measurement during the last decade. A new approach was developed where electromagnetic measurements provide microscopic information on the lithosphere. The present paper is intended to give a history of short-term EQ prediction, and also we hope that this paper reviews the current status of a new science field, 'seismo-electromagnetics'. We make a general review of different phenomena taking place in the lithosphere, atmosphere and the ionosphere, but we pay more attention to the subjects of our preference including lithospheric ultra low frequency (ULF) electromagnetic emissions, and seismo-ionospheric perturbations. © 2010 Taylor & Francis.
