Codon pair bias is the species-specific phenomenon that pairs of adjacent codons appear in genomes with frequencies different than would be predicted under an independence assumption, and thus is indicative of evolutionary selection. The synthetic attenuated virus engineering (SAVE) paradigm to design vaccines creates weak viruses by designing coding sequences that favor underrepresented codon pairs...
The intense demand for video applications from mobile devices brings a challenge to the hardware design, especially in the energy consumption. This work presents a design space exploration to define energy-efficient cache memory configurations for the ME process considering different video sequences and HEVC encoder configurations. We focus on the Motion Estimation (ME) process, known as the most...

This work presents a low-area scalable architecture for the Depth Modelling Mode 1 (DMM-1) encoder of the 3D High Efficiency Video Coding (3D-HEVC) standard, removing the refinement stage. This simplification causes a small BD-rate increase (0.09%) but a significant reduction in memory usage of 30%. The scalable architecture can support different block sizes. Synthesis results for ST 65 nm Standard...

The latest video compression standards, such as the H.264/AVC and the High Efficiency Video Coding (HEVC), provide fast Motion Estimation (ME) algorithms in their reference software aiming at complexity reduction. Test Zone Search (TZS) is the state-of-the-art fast ME algorithm, currently deployed in the reference HEVC encoder due to its great coding efficiency. However, ME is still one of the main...
A few years after standardization of the High Efficiency Video Coding (HEVC), now the Joint Video Exploration Team (JVET) group is exploring post-HEVC video compression technologies. In the intra prediction domain, this effort has resulted in an algorithm with 67 internal modes, new filters and tools which significantly improve HEVC. However, the improved algorithm still suffers from the long distance...
Interactive video streaming requires very low latency and high throughput. Traditional latency based congestion control algorithm performs poorly in fairness. This results in very poor video quality to adaptive video streaming. Software defined networks (SDN) enables us to solve the problem by designing a network controller in the routers. This paper presents a SDN-centric TCP where sending rate of...

A parameter optimization scheme of block interleaver for polar coding with bit-interleaved coded modulation (BICM) is proposed in this paper. We analyze the characteristics of a random interleaver applied to polar codes with high-order modulation, which is ideal but infeasible to implement. Then we derive the parameter optimization algorithm of block interleaver for polar coding with BICM. The block...
Unlike most researches focus on computation reduction, the fast algorithm proposed in this paper aims at maintaining the coding efficiency as high as possible. In the proposed algorithm we employ support vector machine (SVM) that uses three parameters as features: variances, low-frequency AC components of DCT and spatially neighboring CU levels for fast CU size decision. In addition, based upon RMD...
The problem of increasing noise immunity for sending messages usually solved by introducing the additional redundancy or by re-transmission of distorted fragment of the message. At the same time, the resulting delay is not always acceptable. An original concept for irredundant code efficiency rising is discussed. It is shown that some genetic-like algorithm applying to the class of permutative equivalent...
Triangle counting is a key algorithm for large graph analysis. The Graphulo library provides a framework for implementing graph algorithms on the Apache Accumulo distributed database. In this work we adapt two algorithms for counting triangles, one that uses the adjacency matrix and another that also uses the incidence matrix, to the Graphulo library for serverside processing inside Accumulo. Cloud-based...
Currently, Blackbox records all important information that happens during the accident that is Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR).

Emerging resistive non-volatile memory technology (RRAM) is fast gaining importance as a possible successor of Flash memory. Very few experimental studies exist on emerging RRAM that analyze the impact of soft-techniques or purely algorithm driven performance enhancement for such memory devices.

We investigate the problem of index coding, where a sender transmits distinct packets over a shared link to multiple users with side information. The aim is to find an encoding scheme (linear combinations) to minimize the number of transmitted packets, while providing each user with sufficient amount of data for the recovery of the desired parts. It has been shown that finding the optimal linear index...
With the introduction of several new coding tools and technology for depth maps in 3D-HEVC, the coding efficiency is improved at the expense of computational complexity. Meanwhile, the inter-view correlation is not considered and used well for depth maps, while it is developed maturely in texture video coding. Therefore, in this paper, we propose an early determination scheme for the best prediction...
