NIST solicited candidate algorithms for the Advanced Encryption Standard (AES) in a Federal Register Announcement dated September 12, 1997[1]. Fifteen of the submissions were deemed “complete and proper” as defined in the Announcement, and entered the first round of the AES selection process in August 1998. Since that time, NIST has been working with a worldwide community of cryptographers to e...

The study aimed was to determine the best nonlinear function describing growth stages of Japanese quail breed. To this aim, functions such as exponential, logistic, von Bertalanffy, Brody, and Gompertz were used is in description body weight-age relationship male female quails. Multivariate Adaptive Regression Splines (MARS) data mining algorithm applied individual parameters obtained from dete...

Abstract Seismic bearing capacity of strip footings in cohesive soil slopes considering various embedded depths is investigated this study. Novel solutions using pseudo-static method and finite element limit analysis (FELA) with upper bound (LB) lower theorems are presented. The influences footing depth, slope angle, height, undrained shear strength acceleration on failure mechanisms examined d...

On January 14, 2004, the President of the United States announced a new and exciting direction for NASA’s future with his space exploration initiative. This new policy includes the safe return to flight of the Space Shuttle in order to complete the assembly of the Space Station by the end of this decade and to meet our international obligations with the International Space Station. At that time...

Introduction: Space exploration missions are dependent on large vehicles launched from Earth even when the payloads are small. Even though staging would increae the efficiency of missions to other planets and celectial bodies, the massive launch vehicles needed for the completion of such missions make them practically infeasible. If propellants can be produced and stored on the Moon, Mars, etc....

This paper presents a parallel adaptive version of the block-based Gauss-Jordan algorithm used in numerical analysis to invert matrices. This version includes a characterization of the workload of processors and a mechanism of its adaptive folding/unfolding. The application is implemented and experimented with MARS in dedicated and non-dedicated environments. The results show that an absolute e...

Rule based reasoning (RBR) and case based reasoning (CBR) have emerged as two impor­ tant and complementary reasoning methodolo­ gies in artificial intelligence (AI). For problem solving in complex, real world situations, it is useful to integrate RBR and CBR. This paper presents an approach to achieve a compact and seamless integration of RBR and CBR within the base architecture of rules. The ...

This paper reports the performance of the AES finalists, MARS, RC6, Rijndael, Serpent, and Twofish, on the high-end smart card that has a Z80 core with Toshiba’s arithmetic coprocessor.

Mapping surface all-wave net radiation (Rn) is critically needed for various applications. Several existing Rn products from numerical models and satellite observations have coarse spatial resolutions and their accuracies may not meet the requirements of land applications. In this study, we develop the Global LAnd Surface Satellite (GLASS) daytime Rn product at a 5 km spatial resolution. Its al...
