— Trojan insertion has been made difficult in modern communications in the recent years, due to extensive research work in the direction to protect Integrated Circuits (ICs). Several Trojan detection techniques have been developed to prevent the destruction caused by malicious insertion of Trojan in physical layer, making the process of Trojan insertion… (More)
The state of hidalgo, in Mexico, is looking for a model to classify 84 municipalities according to certain economic and social parameters. The model will permit the development of policies for improving the conditions of those municipalities that are lagging behind.

In this paper we compare the performance of several transform coding methods, Discrete Fourier Transform, Discrete Cosine Transform, Wavelets Packet and Karhunen-Loeve Transform, commonly used in image compression systems through experiments. These methods are compared for the effectiveness as measured by rate-distortion ratio and the complexity of… (More)
In this paper we present a method, which can be used to enhance the security of business transactions and confidential information through electronic communication channels. It involves a combination of three scientific disciplines: Cryptography, Steganography, and Chaos.
