New methods for production of pseudo-nondiffracting Bessel light beams with phase singularities of different topological charge have been developed and proved experimentally. It is found out that nonlinear-optical processes of frequency doubling and sum-frequency generation allow to control fori-nation and annihilation of dislocations. the possibility of realization of arithmetic operations using this principle is proved. When Gaussian beam interferes with M-order Bessel beam having M-order dislocation, the dislocation disintegrates on M parallel quasi-nondiffracting beams packed compactly. Rotating of optical beams aggregate on required angle takes place when phase difference between interfering fields is modulated. New principle of optical inter-connections is proposed on this base.
We propose a new parallel algorithm for the single-source shortest-path problem (SSSP). Its heap data structure is particularly advantageous on graphs with a moderate number of high degree nodes. On arbitrary directed...

In order to fulfil real time signal processing tasks such as clutter rejection, moving target detection (MTD) and constant false alarm rate (CFAR) control in airborne radar, an airborne radar parallel signal processing system (ARPS2) is proposed with DSP chips as its kernel processing nodes. the DSP chips are used withparallel architecture. Each node has its private input and output memory. It adopts several parallel techniques, such as parallel storage, parallelprocessing, parallel code loading and parallel data organization to achieve high efficiency. It has a simple structure, excellent flexibility and easiness in developing. ARPS2 is going to be applied to an airborne radar. It can also be applied to perform high-speed real time signal processingalgorithms in other kinds of radar.
