Automorphisms of doubly-even self-dual binary codes
The automorphism group of a binary doubly-even self-dual code is always contained in the alternating group. On the other hand, given a permutation group G of degree n there exists...

Web server protection by customized instruction set encoding
We present a novel technique to secure the execution of a processor against the execution of malicious code (trojans, viruses). The main idea is to permute parts of the opcode val...

Correcting limited-magnitude errors in the rank-modulation scheme
We study error-correcting codes for permutations under the infinity norm, motivated the rank-modulation scheme for flash memories. In this scheme, a set of n flash cells are combin...

Generation of permutations for SIMD processors
Short vector (SIMD) instructions are useful in signal processing, multimedia, and scientific applications. They offer higher performance, lower energy consumption, and better res...

Ranking and Unranking of Hereditarily Finite Functions and Permutations
Prolog's ability to return multiple answers on backtracking provides an elegant mechanism to derive reversible encodings of combinatorial objects as Natural Numbers i.e. ranki...
