TCP over low-power and lossy networks: tuning the segment size to minimize energy consumption

, 2010
Low-power and Lossy Networks (LLNs), like wireless networks based upon the IEEE 802.15.4 standard, have strong energy constraints, and are moreover subject to frequent transmission errors, not only due to congestion but also to collisions and to radio ...

Ultra-Sparse Non-Binary LDPC Codes for Probabilistic Amplitude Shaping

, 2017
This work shows how non-binary low-density parity-check codes over GF($2^p$) can be combined with probabilistic amplitude shaping (PAS) (B\"ocherer, et al., 2015), which combines forward-error correction with non-uniform signaling for power-efficient ...

Learning from your mistakes: The functional value of spontaneous error monitoring in aphasia

Frontiers in Psychology, 2014
Self-monitoring of errors in picture naming has been shown to correlate positively with aphasia treatment outcomes (Marshall et al., 1994). To explore potential explanations, we took advantage of aphasics’ item-level inconsistency in naming accuracy, e ...

Design of Crosstalk Prevention Coding scheme based on Quintuplicated Manchester error correction method for Reliable on chip Interconnects

Advances in Electrical and Computer Engineering, 2018
A low power Manchester based error-control code for on-chip interconnection-link has been proposed in this paper. It has a capacity to rectify nonuple errors of random and burst using standard N-Modular Redundancy (N-MR) error correction scheme ...

Embedding Protection Inside H.264/AVC and SVC Streams

EURASIP Journal on Wireless Communications and Networking, 2010
A backward compatible error-protection mechanism embedded into the H.264 (AVC or SVC) syntax is described. It consists of the addition into the H.264 bitstream of supplementary network abstraction layer (NAL) units that contain forward error-correction (

The Expectation Theory: Tests on French, German, and American Euro-Rates. [PDF]

This paper deals with tests of the expectations hypothesis of the term structure on French, German, UK and US short-term interest rates. Three tests are examined: the first is based on forward rates and the other two are based on the interest rates ...
