How to automatically parallel large amount of sequential legacy code has become one of the key issues, especially for domain specific scientific applications. It is more urgent as multi-core processors are increasingly popular. Taking the extremely compute and I/O intensive prestack migration application of the geophysics exploration as an example, this paper discusses its algorithms and implementations,...
We present applications of recently developed algorithms for data-driven nonlinear systems identification to the study of cardiovascular and respiratory control mechanisms on an integrated systems level, utilizing experimental data obtained during resting conditions. Specifically, we consider cerebrovascular regulation during normal conditions in a two-input context, as well as respiratory control...
In this paper, new discretized models of fractional order differentiator (FOD) (sr) and fractional order integrator (FOI) (s-r) based on first and higher order operators are proposed. Specifically in this work, one-third (s??1/3) and one-fourth (s??1/4) order differentiator and integrator models based on first order Al-Alaoui and Hsue operator, second order Schneider operator and third order Al-Alaoui...
A novel small target detection method based on 2-D Generalized S-transform is proposed in this paper. A four dimensional array was obtained after the 2-D Generalized S-transform of an image and the energy sum of nonzero frequency components in the S-transform domain can be computed. Comparing the energy sum of nonzero frequency components with a predefined threshold at each point, the position of...
In this paper a global co-simulation methodology for concurrent/simultaneous analysis of passive and active analog/digital parts is proposed. An original power-signature concept is introduced to model high-speed digital modules temporal and spatial distribution of their power switching activity through specified chip partitions. Dedicated real-world NXP-Philips-Semiconductors active modules mounted...
Electro-Mechanical Actuator (EMA) is a typical position servo-system, widely used in many fields. The control architecture of EMA is usually implemented based on cascaded position, velocity and current loop. The BLDCM is more and more applied to EMA because of its small size, high efficiency, high power density and low rotor inertia. A Position Servo-System of BLDCM (PSSBLDCM) used in EMA is designed...
