In the present paper the authors have introduced a new symmetric key cryptographic method called Bit Level Encryption Standard(BLES) which is based on bit exchanging or bit reshuffling method. The authors have introduced a completely new bit level encryption method. Nath et. al has already developed bit manipulation method called NJJSAA where the authors mainly used bit level right shift, bit l...

Simultaneously long short (SLS) feedback trading strategies are known to yield positive expected gain by zero initial investment for price processes governed by, e.g., geometric Brownian motion or Merton’s jump diffusion model. In this paper, we generalize these results to positive prices with stochastically independent multiplicative growth and constant trend in discrete and continuous time as...

The spread use of virtual learning environments presents a great potential for the development of applications which meet educational area needs. In view of the importance of a more dynamic implementation and that it will be able to continuously adapt to the students needs, it was proposed and developed the U-SEA (System of Teaching Adapted Ubiquitous). A software built on the basis of virtual ...

this paper examines differences in performances of a range of torsionally stiff and flexible single story buildings designed with the provisions of iranian standard 2800. seismic nonlinear dynamic time history behavior of eight building models subjected to seven horizontal bi-directional design spectra compatible ground motions are investigated. these models cover a wide range of very torsional...

ON 16 DECEMBER 1gg 1, I gave the seventh Sol M. Malkin Lecture in Bibliography on “The Future of Rare Book Libraries” at the School of Library Service (SLS) ,Columbia University.” (In assessing this honor, bear in mind that I am the person principally responsible for selecting Malkin Lecturers.) The Book Arts Press published the first six Malkin Lectures as separate pamphlets, most of them eleg...
