Research in spatial navigation revealed the existence of discrete strategies defined by the use of distinct reference frames during virtual path integration. The present study investigated the distribution of these navigation strategies as a function of gender, video gaming experience, and self-estimates of spatial navigation abilities in a population of 300 subjects. Participants watched video...

Most synthesis strategies for solution synthesis in distributed expert systems (DESs) are developed based on analytic methods or in-ductive methods. A synthesis strategy presented in this paper is developed by case-based reasoning based on an analogical method. In this paper, the basic frame work of the strategy is introduced and preliminary results are demonstrated. Furthermore, this strategy ...

In previous work the 3D-Wave parallelization strategy was proposed to increase the parallel scalability of H.264 video decoding. This strategy is based on the observation that inter-frame dependencies have a limited spatial range. The previous results, however, investigate application scalability on an idealized multiprocessor. This work presents an implementation of the 3D-Wave strategy on a m...

Hand gesture recognition is very important to communicate in sign language. In this paper, an effective object tracking and hand gesture recognition method is proposed. This method is combination of two well-known approaches, the mean shift and the motion detection algorithm. The mean shift algorithm can track objects based on the color, then when hand passes the face occlusion happens. Several...

in this paper we introduce and study besselian $g$-frames. we show that the kernel of associated synthesis operator for a besselian $g$-frame is finite dimensional. we also introduce $alpha$-dual of a $g$-frame and we get some results when we use the hilbert-schmidt norm for the members of a $g$-frame in a finite dimensional hilbert space.
