The effect of a small amount of noise on the standard mapping is considered. Whenever the standard mapping possesses accelerator modes (where the action increases approximately linearly with time), the diffusion coefficient contains a term proportional to the reciprocal of the variance of the noise term. At large values of the stochasticity parameter, the accelerator modes exhibit a universal b...

This paper presents a novel hardware/software Co-Design framework CoDe-X for automatic generation of Xputer based accelerators. CoDe-X accepts C-programs and carries out both, the host/accelerator partitioning for performance optimization, and (second level) the parameter-driven sequential/structural partitioning of the accelerator source code to optimize the utilization of its reconfigurable d...

We have previously proposed a method for finding integrable, four-dimensional symplectic maps. The method relies on solving for parameter values at which the linear stability factors of the fixed points of the map have the values corresponding to integrability. We suggest that this method be applied to accelerator lattices in order to increase dynamic aperture. We have now implemented a numeric...

Through fitting to numerical results we obtain a simple model for the transverse short-range wakefield of a linear accelerator structure over a parameter range useful for the NLC.

We show that mode locking finds a purely quantum nondissipative counterpart in atom-optical quantum accelerator modes. These modes are formed by exposing cold atoms to periodic kicks in the direction of the gravitational field. They are anchored to generalized Arnol'd tongues, parameter regions where driven nonlinear classical systems exhibit mode locking. A hierarchy for the rational numbers k...

Mathematical simulation of biological processes is a big challenge in both of biology and computer science. This enables biologists to approach the mechanism of life as systems, however, it’s an extremely computation intensive tasks. We’ve developed an FPGA-based hardware accelerator for biochemical simulations. This accelerator has a dedicated pipeline to solve ODEs by its dedicated pipeline m...

In this paper, mechanical behavior of polyester with varying parameters of curing were investigated. Binder content, accelerator content, temperature and time were ascertained as parameters during curing of polyester specimens. Three levels of each parameter were selected and taguchi techniques are implemented. It was observed that curing time and binder content influenced mechanical properties...
