On a Class of Traceability Codes
Traceability codes are designed to be used in schemes that protect copyrighted digital data against piracy. The main aim of this paper is to give an answer to a Staddon-Stinson-We...

LDPC Codes from Triangle-Free Line Sets
We study sets of lines of AG(n, q) and PG(n, q) with the property that no three lines form a triangle. As a result the associated point-line incidence graph contains no 6-cycles a...

Register Synthesis for Algebraic Feedback Shift Registers Based on Non-Primes
In this paper, we describe a solution to the register synthesis problem for a class of sequence generators known as Algebraic Feedback Shift Registers. These registers are based o...

Some Indecomposable t-Designs
The existence of large sets of 5-(14,6,3) designs is in doubt. There are five simple 5-(14,6,6) designs known in the literature. In this note, by the use of a computer program, we...

On Non-Polynomial Latin Squares
A Latin square L = L( ij) over the set S = {0, 1, . . . , n - 1} is called totally non-polynomial over Zn iff

Periodicity and Correlation Properties of d-FCSR Sequences
A d-feedback-with-carry shift register (d-FCSR) is a finite state machine, similar to a linear feedback shift register, in which a small amount of memory and a delay (by d-clock c...

Extensions of Generalized Product Caps
We give some variants of a new construction for caps. As an application of these constructions we obtain a 1216?cap in PG(9, 3) a 6464?cap in PG(11, 3) and several caps in ternary...

Parameter Inequalities for Orthogonal Arrays with Mixed Levels
An important question in the construction of orthogonal arrays is what the minimal size of an array is when all other parameters are fixed. In this paper, we will provide a genera...
