in this paper, we propose a new full-fuzzy video ratecontrol algorithm (rca) for variable bit rate (vbr) videoapplications. the proposed rca provides high qualitycompressed video with a low degree computational complexity.by controlling the quantization parameter (qp) on a picturebasis, it produces vbr video bit streams. the proposed rcahas been implemented on the jm h.264/avc video codec andth...

Switch and stay combining (SSC) is an attractive diversity technique due to its low complexity and compatibility to resourceconstrained wireless networks. This letter proposes a distributed SSC for partial relay selection networks in order to achieve spatial diversity as well as to improve spectral efficiency. Simulation results show that the performance loss (in terms of bit error probability)...

Love may have been a female invention long ago, when the brain of genus homo became large and required more food. Thus the father was needed to help feed mother and baby. Pekalski [1] assumed mate selection to be governed by a Major Histocompatibility Complex MHC. In the same spirit now the sexual Penna ageing model is modified to include mate selection by an additional string of 32 bits for ea...

in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...

Several useful associative memory algorithms deal with identifying extreme values (maximum or minimum) in a specified field of a selected subset of words. Previously proposed algorithms for such extreme-value searches are bit-sequential in nature, even when implemented on fully parallel associative memories. We show how the multiple-bit search capability of a fully parallel associative memory c...

In this paper, we present a new classification of 4-bit optimal S-boxes. All optimal 4-bit Sboxes can be classified into 183 different categories, among which we specify 3 platinum categories. Under the design criteria of the PRESENT (or SPONGENT) S-box, there are 8064 different S-boxes up to adding constants before and after an S-box. The 8064 S-boxes belong to 3 different categories, we show ...

Since the H.264 video coding standard becomes quite popular for transmission of diverse multimedia data due to its high coding efficiency, bit allocation and buffer management schemes are required for various applications. In this paper, we propose a new bit rate control algorithm for H.264 based on an accurate bit allocation strategy, where we introduce a reference quantization parameter (QP) ...
