Steganography is the art of hiding and transmitting data through apparently innocuous carriers in an effort to conceal the existence of the data. A lot of steganography algorithms have been proposed recently. Many of them use the digital image data as a carrier. In data hiding scheme of halftoning and coordinate projection, still image data is used as a carrier, and the data of carrier image ar...

Machine Translation, (hereafter in this document referred to as the "MT") faces a lot of complex problems from its origination. Extracting multiword expressions is also one of the complex problems in MT. Finding multiword expressions during translating a sentence from English into Urdu, through existing solutions, takes a lot of time and occupies system resources. We have designed a simple rela...

For public key cryptosystems multiplication on elliptic curves can be used instead of exponentiation in finite fields. One attack to such a system is: embedding the elliptic curve group into the multiplicative group of a finite field via weilpairing; calculating the discrete logarithm on the curve by solving the discrete logarithm in the finite field. This attack can be avoided by constructing ...

The Oriented Supersingular Isogeny Diffie–Hellman is a post-quantum key exchange scheme recently introduced by Colò and Kohel. It based on the group action of an ideal class quadratic imaginary order subset supersingular elliptic curves, in this sense it can be viewed as generalization popular isogeny CSIDH. From algorithmic standpoint, however, OSIDH quite different from In sense, uses groups ...

Let E1 and E2 be two elliptic curves over an algebraically closed field K. The purpose of this paper is to study the question of whether or not the product surface E1 × E2 can be the Jacobian of a (smooth, irreducible) curve C of genus 2. By properties of the Jacobian, this question is equivalent to the question of whether or not there is such a curve C on E1 × E2. This question was first inves...

We study K3 surfaces with 9 cusps, i.e. disjoint A 2 configurations of smooth rational curves, over algebraically closed fields characteristic p ? 3 . Much like in the complex situation studied by Barth, we prove that each such surface admits a triple covering an abelian surface. Conversely, determine which order three automorphisms give rise to surfaces. also investigate how cusps hit supersin...

Ensemble learning algorithms such as AdaBoost and Bagging have been in active research and shown improvements in classification results for several benchmarking data sets with mainly decision trees as their base classifiers. In this paper we experiment to apply these Meta learning techniques with classifiers such as random forests, neural networks and support vector machines. The data sets are ...

This paper proposes a neural network weights and topology optimization using genetic evolution and the backpropagation training algorithm. The proposed crossover and mutation operators aims to adapt the networks architectures and weights during the evolution process. Through a specific inheritance procedure, the weights are transmitted from the parents to their offsprings, which allows re-explo...

The Main Conjecture of Iwasawa theory for an elliptic curve E over Q and the anticyclotomic Zp-extension of an imaginary quadratic field K was studied in [BD2], in the case where p is a prime of ordinary reduction for E. Analogous results are formulated, and proved, in the case where p is a prime of supersingular reduction. The foundational study of supersingular main conjectures carried out by...
