Automatic ei

This paper describes a general approach for automatically programming a behavior-based robot. New behaviors are learned by trial and error using a performance feedback function as reinforcement. Two algorithms for behavior learning are described that combine techniques for propagating reinforcement values temporally across actions and spatially across states. A behavior-based robot called OBELI...

EI / c from the lattice *

Results from a lattice calculation of the matrix elements of the weak Hamiltonian which determine c’ are presented. They suggest a smaller value of 8/c than previously estimated.

Amalgamation of Cyclic Bit Operation in SD-EI Image Encryption Method: An Advanced Version of SD-EI Method: SD-EI Ver-2

In this paper, the author presents an advanced version of image encryption technique, which is itself an upgraded version of SD-EI image encryption method. In this new method, SD-EI Ver-2, there are more bit wise manipulations compared to original SD-EI method. The proposed method consist of three stages: 1) First, a number is generated from the password and each pixel of the image is converted...

The chromospherically active binary star EI Eridani

We present a detailed determination of the astrophysical parameters of the chromospherically active binary star EI Eridani. Our new radial velocities allow to improve the set of orbital elements and reveal long-term variations of the barycentric velocity. A possible third-body orbit with a period of ≈ 19 years is presented. Absolute parameters are determined in combination with the Hipparcos pa...
