10.11591/ijeecs.v3.i3.pp639-645
Ali Madi , Yadong He , Lilong Jiang , Baorui Yan
Polymeric insulators need proper management and maintenance. Without proper management, the electric devices can be affected by factors such as leakages in the electricity system. In outdoor insulation, the environment subjects the material to a variety of stresses simultaneously that can lead to rapid degradation and loss of the insulation properties. Contamination of the surface of the insulating material, aging, electrical and mechanical stress are some of the forces that will result in the failure of the insulating material. To improve their reliability, research into the formulation of the material and the development of standards to eliminate creepage are being done. This work looks at the phenomenon of surface tracking. It investigates the actual process and looks at the possible types of surface tracking on polymeric insulators used under different environments. This also gives a short description of the emergence of polymeric insulators into the market.

To convey the information safely DNA grouping mechanisms are used. There are many methods used by DNA sequences. The proposed method is of both encryption and information concealing utilizing a few properties of Deoxyribonucleic Acid (DNA) groupings. This technique is highlighted that DNA groupings have many more intriguing properties which are used for concealing the information. There are three strategies in this encryption strategy: the Insertion Technique, the Complimentary Pair Technique and the Substitution Strategy .For every single strategy, a specific reference DNA grouping P is chosen and then the taken sequence is changed over with the mystery message M and is consolidated, so that P0 is acquired. P0 is then sent to the collector and the beneficiary can recognize and separate the message M covered up in P. This technique is proposed to utilize INSERTION Strategy. Subsequently, the proposed plan comprises for the most part of two stages. In the principal stage, the mystery information is encoded utilizing a DNA Sequence. In the second stage the encoded information is steganographically covered up into some reference DNA grouping utilizing an insertion strategy. The effectiveness of this security algorithm is seen with many merits and limitations. A, C, G, and T are the 4 nucleotides which are taken for this project.
