It is shown that amplification of the magnetic field in supernova remnants (SNRs) occurs in all six objects where morphological measurements are presently available in the hard X-ray continuum at several keV. For the three archetypical objects (SN 1006, Cas A and Tycho’s SNR) to which nonlinear time-dependent acceleration theory has been successfully applied up to now, the global theoretical an...

This paper presents an acceleration control of an electrodynamic shaker that cannot employ the iteration control method freely. There are considerable points in the design phase of the acceleration controller. The transfer functions using the acceleration controlled variable have zero at the origin and two crossover frequencies. It is not easy to design the acceleration controller by using the ...

Offloading the complex computational kernel from the processor is the common way to improve performance of embedded system. In our work we are using MicroBlaze softcore processor in design and implementation of acceleration framework. In acceleration framework MicroBlaze is coupled with co-processor with the help of communication bus. We can attach the co-processor to our design that can handle...

We apply our object-oriented design environment PAM-Blox to dynamic generation of circuits for re-conngurable computing. Our approach combines the structural hardware design environment with commercial synthesis of nite state machines (FSMs). The PAM-Blox environment features a well deened hardware object interface and the ability to control the placement of hand-optimized circuits. We integrat...

A conceptual design of a muon acceleration scheme based on recirculating superconducting linacs is proposed. In the presented scenario, acceleration starts after ionization cooling at 245 MeV/c and proceeds to 20 GeV, where the beam is injected into a neutrino factory storage ring. The key technical issues are addressed; such as: the choice of acceleration technology (superconducting versus nor...

The formulation of the process of analog system design has been done on the basis of the control theory application as the problem of a special functional minimization. This approach generalizes the design process and produces the different design trajectories inside the same optimization procedure. Numerical examples show that the potential computer time gain of the optimal design strategy wit...

An LSI is fabricated and measured to demonstrate the feasibility of the VDD-hopping scheme in a system level. In the scheme, supply voltage, VDD, is dynamically controlled through software depending on workload. The VDD-hopping scheme is shown to reduce the power to less than 1/4 compared with the conventional fixed-VDD scheme. The power saving is achieved without degrading the real-time featur...
