We present the expected variability features in the context of the Synchro-Self-Compton (SSC) model of emission from Active Galactic Nuclei (AGNs). We show that the homogeneous SSC model can describe well the observed mul-tiwavelength spectrum and variability of objects such as Mkn 421 and Mkn 501; however in order to explain the very fast flaring timescales occasionally observed from these obj...

This paper proposes the dynamic window approach to reactive collision avoidance for mobile robots equipped with synchro-drives. The approach is derived directly from the motion dynamics of the robot and is therefore particularly well-suited for robots operating at high speed. It di ers from previous approaches in that the search for commands controlling the translational and rotational velocity...

A systematic program to explore stability of orbits in hadron storage rings is based on the following steps: (a) beginning with a symplectic tracking code, construct the mixed-variable generator of the full-turn map in a Fourier-spline basis; (b) use the resulting fast mapping to follow long orbits and estimate the long-term dynamic aperture; (c) contruct quasi-invariants and examine their vari...

A protected left turn phase is often used at intersections with heavy left turns. This may induce a capacity gap between adjacent intersections along the arterial road among which only parts of intersection are with protected left turn phase. A model for integrated optimization of protected left turn phases for adjacent intersections along the arterial road is developed to solve this problem. T...

Curved broad-band spectral distributions of non-thermal sources like blazars are described well by a log-parabolic law where the second degree term measures the curvature. Log-parabolic energy spectra can be obtained for relativistic electrons by means of a statistical acceleration mechanism whose probability of acceleration depends on energy. In this paper we compute the spectra radiated by an...
