A two-fold way to increase the sensitivity of the optical sensor is proposed and numerically investigated. The sensor based on the coupled photonic crystal cavities is calculated as an illustration of the proposed approach. The correspondence between analytical and numerical modeling approach is demonstrated.

The results of computational studies of the radiation characteristics and mass of the structures in the VVER-1200 reactor facility in the AES-2006 design with respect to the activity group as a function of the holding period after final shutdown of the power-generating unit are presented. The three-dimensional program KATRIN was used to obtain the radiation characteristics. It is shown that after final shutdown all metal structures in VVER-1200 will remain radioactive wastes for up to 150 years and the concrete structures after a holding period of more than 60 years will remain in the radioactive materials category.

ABSTRACT:In this paper a new approach for moving objects detection in video surveillance systems is proposed. It is based on iLBP (intensity local binary patterns) descriptor that combines the classic LBP (local binary patterns) and the multiple regressive pseudospectra model. The iLBP descriptor itself is considered together with computational algorithm that is based on the sign image representation. We show that motion analysis methods based on iLBP allow uniformly detecting objects that move with different speed or even stop for a short while along with unattended objects. We also show that proposed model is comparable to the most popular modern background models, but is significantly faster.
