On Reverse-Free Codes and Permutations

SIAM Journal on Discrete Mathematics, 2010
A set $\mathcal{F}$ of ordered $k$-tuples of distinct elements of an $n$-set is pairwise reverse free if it does not contain two ordered $k$-tuples with the same pair of elements in the same pair of coordinates in reverse order. Let $F(n,k)$ be the maximum size of a pairwise reverse-free set.

Reverse Multi-Delimiter Compression Codes

2020 Data Compression Conference (DCC), 2020
An enhanced version of a recently introduced family of variable length binary codes with multiple pattern delimiters is presented and discussed. These codes are complete, universal, synchronizable, they have monotonic indexing and allow a standard search in compressed files.

Reversible Codes and Applications to DNA

2014
In this study we focus on codes over a special family of commutative rings where we are able to construct a map that gives a correspondence between k-bases (k-letter words) of DNA with elements of the ring. By making use of so called coterm polynomials, we are able to solve the reversibility and complement problems in DNA codes and construct DNA codes ...

Reversible subband coding of images

Systems and Computers in Japan, 1995
AbstractIn conventional 1D filter banks used for reversible subband coding of gray‐level still images, the high‐band signals are extrapolative or interpolative prediction error signals, the former using one side of the pixels alone and the latter using two sides of the pixels but with levels four times that of the input signals.This paper proposes a ...

Forward and reverse coding for bacteria nanonetworks

2013 First International Black Sea Conference on Communications and Networking (BlackSeaCom), 2013
In this paper we present a simple coding scheme for communication between nanomachines that utilizes bacteria as information carriers. In particular, we utilize two main properties of bacteria to facilitate communication, which includes their ability to swim within the medium, as well as the mechanism to transfer information between each other through ...

Reversibility and efficiency in coding protein information

Journal of Theoretical Biology, 2010
Why the genetic code has a fixed length? Protein information is transferred by coding each amino acid using codons whose length equals 3 for all amino acids. Hence the most probable and the least probable amino acid get a codeword with an equal length.

Resolution Scalable Image Coding With Reversible Cellular Automata

IEEE Transactions on Image Processing, 2011
In a resolution scalable image coding algorithm, a multiresolution representation of the data is often obtained using a linear filter bank. Reversible cellular automata have been recently proposed as simpler, nonlinear filter banks that produce a similar representation.

Sequentially-Constructible Reversible Variable Length Codes

IEEE Transactions on Communications, 2014
Dominant codelength sequences for reversible variable length codes (RVLCs) have been recently introduced and studied as a means to looking into optimal RVLCs. However, obtaining the dominant sequences for RVLCs is computationally challenging. In this paper, we consider a special subset of all RVLCs, namely, the sequentially-constructible (SC) RVLCs ...
