Abstract—


A geometric relationship and mathematical model of pressure angle of elliptical gears are developed based on the theory of gearing, and some constraints of pressure angle are presented in order to prevent gear teeth from coming out of mesh. The results show that the ....etc

ECC is a public key encryption technique based on elliptic curve theory. ECC can be used to create faster, smaller and more efficient cryptographic keys. It generates keys through the properties of the elliptic curve equation rather than the traditional method of generation, as the product of very large prime numbers. This technology can be used in conjunction with most of the public key encryption methods such as RSA and Diffie-Hellman.


ECC can yield a level of security with a 164-bit key compared with other systems that require a 1,024-b ....etc

Abstract
This paper presents an energy conservation scheme, Maximum Unavailability Interval (MUI), to improve the energy efficiency for the Power Saving Class of Type II in IEEE 802.16e. By applying the Chinese Remainder Theorem, the proposed MUI is guaranteed to find the maximum Unavailability Interva ....etc

Abstract :

This seminar deals with the determination of the position and orientation of a mobile robot from distance measurements provided by a belt of onboard ultrasonic sensors. The environment is assumed to be two-dimensional, and a map of its landmarks is available to the robot. In this context, classical localization methods have three main limitations. First, each data point provided by a sensor must be associated with a given land ....etc

This innovative technology can produce smaller, faster and efficient cryptographic keys using the break through technique of elliptic curve equation rather than employing the traditional method of producing the key as the product of very large prime numbers. Although ECC can be used in collaboration with other public key encryption methods like the RSA, and Diffie-Hellman, it gains upper hand over the other encryption methods in the level of security it offers. A 164-bit ECC key can provide with an equivalent amount of security that a 1024-bit ....etc

ABSTRACT

The main objective of our Project is to show that Elliptical Curve Cryptography is better than RSA. Which means than the ECC maintains a constant key size regarding the amount of data transferred i.e. the key size will be constant where as in RSA key size varies with increase in transfer of data. By having this type of properties this algorithm can be used in different applications efficiently. This algorithm is widely applicable to the huge organizations like military. As in the military network large amounts of very ....etc
