Centralized versus decentralized control - A solvable stylized model in transportation

Today's supply networks consist of a certain amount of logistics objects that are enabled to interact with each other and to decide autonomously upon their next steps: in other words, they exhibit a certain degree of autonomous cooperation. Therefore, mode ...

RVC-CAL dataflow implementations of MPEG AVC/H.264 CABAC decoding

Marco Mattavelli, Endri Bezati

This paper describes the implementation of the MPEG AVC CABAC entropy decoder using the RVC-CAL dataflow programming language. CABAC is the Context based Adaptive Binary Arithmetic Coding entropy decoder that is used by the MPEG AVC/H.264 main and high pro ...

Diffusion LMS Strategies for Distributed Estimation

Ali H. Sayed

We consider the problem of distributed estimation, where a set of nodes is required to collectively estimate some parameter of interest from noisy measurements. The problem is useful in several contexts including wireless and sensor networks, where scalabi ...

Sharp Bounds for Optimal Decoding of Low Density Parity Check Codes

Nicolas Macris, Shrinivas Kudekar

Consider communication over a binary-input memoryless output-symmetric channel with low density parity check (LDPC) codes and maximum a posteriori (MAP) decoding. The replica method of spin glass theory allows to conjecture an analytic formula for the aver ...

On MLP-based Posterior Features for Template-based ASR

Hervé Bourlard, Joel Praveen Pinto, Serena Soldo

We investigate the invariance of posterior features estimated using MLP trained on auxiliary corpus towards different data condition and different distance measures for matching posterior features in the context of template-based ASR. Through ASR studies o ...

CAL Dataflow Components For an MPEG RVC AVC Baseline Encoder

Marco Mattavelli, Ihab Mostafa Amin Mohamed Amer, Karim Maarouf, Hussein Aman-Allah, Ehab Hanna

In this paper, an efficient H.264/AVC baseline encoder, described in RVC-CAL actor language, is introduced. The main aim of the paper is two folds: a) to demonstrate the flexibility and ease that is provided by RVC-CAL, which allows for efficient implement ...

Towards a Comprehensive RVC VTL: A CAL Description of an Efficient AVC Baseline Encoder

Ihab Mostafa Amin Mohamed Amer, Karim Maarouf, Hussein Aman-Allah, Ehab Hanna

The Video Tool Library (VTL) is one of the major normative components of the Reconfigurable Video Coding (RVC) standard. It specifies the set of functional units (FUs)that may be interchangeably combined and connected to form different video codecs, with v ...

Arithmetic Coding of Sub-Band Residuals in FDLP Speech/Audio Codec

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

A speech/audio codec based on Frequency Domain Linear Prediction (FDLP) exploits auto-regressive modeling to approximate instantaneous energy in critical frequency sub-bands of relatively long input segments. The current version of the FDLP codec operating ...
