Improved Color Image Steganographic Technique in Transform Domain

Steganography is the process of embedding original message bits on some carrier file. The carrier file may be text file, image file, audio file or video file etc. If that carrier file is an image file, then that technique is called Image steganography [1]. If color image is used as a carrier file to embed data bits, then that type of steganography technique is called as color image steganography [7]. In this proposed work, embedding the original message bits in the transform domain of the carrier color image without considering the green plane, hence it is resulting in high quality stego image. Hence this technique is called as improved color image steganography technique in transform domain. Here in this paper, DCT (Discrete Cosine Transform) technique has been used.

Physicochemical Studies on Schiff Bases Derived from Substituted Coumarins with Substituted Diamines in Aqueous-Alcohol Medium

Schiff bases derived from substituted coumarins with substituted diamines were synthesized by cyclo-condensation. Proton-ligand ionization constants and metal-ligand stability constants at constant ionic strength in aqueous-alcohol medium (50/50% V/V) were evaluated using Irving-Rossotti method. The ligands exhibit pKa values around 11.5 due to the phenolic –OH group. The metal ligand stability constants with Cu (II), Co(II), Ni(II), Zn(II), Cd(II) and Hg(II) were also determined. The effects of substitutions on the stability constants were studied.

Class Imbalance Problem in Data Mining using Probabilistic Approach

Class imbalance problem are raised when one class having maximum number of examples than other classes. The classical classifiers of balance datasets cannot deal with the class imbalance problem because they pay more attention to the majority class. The main drawback associated with it majority class is loss of important information. The Class imbalance problem is a difficult due to the amount and nature of data. This paper focuses different methods of class imbalance problem. It is been considered the majority class to achieve the class imbalanced problem. This paper mainly focuses the minority class sample to achieve the problem and proposed method for class imbalance problem using minority sample data. The oversampling and undersampling both concept were used to identify the correct class label of the sample using probabilistic approach, the main objective of this paper, to proposed method to minimize the misclassification rate of minority class sample, balance and classify the data more accurately thereby improving the performance of classifier.

A Review on Wireless Transport Layer Security

Wireless Application Protocol (WAP) is one of the technical standards for information over a mobile wireless network. Mobile devices such as mobile phones that use the protocol have a WAP browser as a web browser. WTLS (wireless transport layer security) inherited from TLS (Transport Layer Security). WTLS uses similar semantics adapted for a low bandwidth mobile device. As compared to TLS main changes are compressed data structures where possible packet sizes are reduced by using bit-fields, discarding redundancy and truncating some cryptographic elements. WTLS defines a compressed certificate format. This broadly follows the X.509 v3 certificate structure, but uses smaller data structures. Packet based design TLS is designed for use over a data stream. WTLS adapts that design to be more appropriate on a packet based network. WTLS design is based on a requirement that it be possible to use a packet network such as SMS as a data transport. There are number of WTLS security issues. WTLS processing more is fast as compared to using SSL. So it is suitable for wireless system. WTLS uses modern cryptography tools to enhance security. WTLS can provide different level of security for privacy, data integrity and authentications.

Antibacterial and Antifungal Activity from Seed Extracts Of Peganum Harmala

The aim of the study was to determine the strong antimicrobial and antifungal activity from the extracts of Peganum Harmala plant species by solvent extraction procedure. P. harmala seeds extract contains several important alkaloids such an important Oxamide compound was used for this study. Extracted product was isolated, purified and identified by Thin Layer Chromatography, UV-VIS Spectroscopy, FT-IR Spectroscopy and 1H-NMR, 13C-NMR Spectroscopy. Finally, the isolated compound Oxamide activity was checked and proved through the Candida albicans, Klebsiella pneumonia and Pseudomonas aeruginosa with MIC studies.

An Approach for Reduction in Power Consumption in Low Voltage Dropout Regulator

A low-dropout or LDO regulator is a DC linear voltage regulator which can control the output voltage even when the supply voltage is very close to the output voltage. The advantages of a low dropout voltage regulator include the absence of switching noise ( as no switching takes place), smaller device size ( as neither large inductors nor transformers are needed), and greater design simplicity (usually consists of a reference, an amplifier and a pass element). A significant adiabatic logic with 180 nm CMOS technology is proposed to reduce impact of power supply reductions well as a simple symmetric operational transconductance amplifier is used as the error amplifier (EA), with a current splitting method adopted to increase the gain and also improves the bandwidth of the LDO regulator.
