The latest video coding standard, versatile (VVC), has greatly improved efficiency over its predecessor standard high (HEVC), but at the expense of sharply increased complexity. In context perceptual (PVC), visual saliency model that utilizes characteristics human system to improve become a reliable method due advances in computer performance and algorithms. this paper, novel VVC optimization s...

The versatile video coding (VVC) standard offers improved efficiency compared to the high (HEVC) in multimedia signal coding. However, this increased comes at cost of complexity. This work proposes an efficient unit partitioning algorithm based on extreme learning machine (ELM), which can reduce complexity while ensuring efficiency. Firstly, size decision is modeled as a classification problem....

Network coding technology is a new communication paradigm that is superior to traditional routing in many aspects, especially in terms of the ability of increasing multicast throughput (Ahlswede et al., 2000; Li et al., 2003). Traditional routing adopts store-andforward data forwarding scheme at every intermediate node that simply replicates and forwards the incoming data to downstream nodes. H...

Region-based video coding schemes employed in MPEG-4 is also promising for still image coding applications where images contain a number of objects that can be encoded at different bit rates, such as compression of medical images for archiving and tranmission. Motivated by this fact, in this paper we investigate multi-region and multi-quality (MRMQ) coding based on zerotree wavelet coders. We p...

Cooperation in wireless networks has been recently considered as a technique to increase the network throughput. However, for sensor networks with limited available energy, this benefit may come at the expense of a increased energy consumption due to the simultaneous transmission by many nodes. In this paper we consider the bit per Joule achievable rate (AR) as a performance measure of a cooper...

Three distinct ribosomal RNA (rRNA) transcription units (rDNA units), designated A, B and C, were identified in the intraerythrocytic protozoan parasite, Babesia bigemina. These rDNA units were cloned, and restriction maps were constructed showing the approximate location of the small and large rRNA coding regions. The arrangement of the genes in the genome and copy number analysis suggests the...
