We present new families of three-dimensional (3-D) optical orthogonal codes for applications to optical code-division multiple access (OCDMA) networks. The families are based in the extended rational cycle used for the 2-D Moreno-Maric construction.

The linear complexity of a sequence is an important parameter for many applications, especially those related to information security, and hardware implementation. It is desirable to develop a corresponding measure and theory for multidimensional arr

We compute the covering radius of some families of binary cyclic codes. In particular, we compute the covering radius of cyclic codes with two zeros and minimum distance greater than 3. We also compute the covering radius of some binary primitive BCH

We present q new asymptotically optimal families of doubly periodic arrays with ideal auto and cross correlation constraints, derived from the Moreno-Maric construction for frequency hopping applications. These new families possess the same propertie

The ability to design effective solutions using parallel processing should be a required competency for every computing student. However, teaching parallel concepts is sometimes challenging and costly, specially at early stages of a computer science

We present Toa, a web-based Network Flow data monitoring system (NMS). Toa consists of a collection of scripts that automatically parse network flow data, store this information in a database system, and generate interactive time line charts for netw
In this work we present two generators for the group of symmetries of the generic $(m+1)$ dimensional periodic Costas arrays over elementary abelian $(\mathbb{Z}_p)^m$ groups: one that is defined by multiplication on $m$ dimensions and the other by s

The enumeration of two-dimensional Costas arrays is a problem with factorial time complexity and has been solved for sizes up to 29 using computer clusters. Costas arrays of higher dimensionality have recently been proposed and their properties are b

The enumeration of Costas arrays is a problem that grows factorially with input size and that has lately been completed for sizes up to 28 using computer clusters. This paper presents designs for solving this problem using, separately, GPUs and FPGAs

New families of three-dimensional (3-D) optical orthogonal codes for applications to optical code-division multiple access (OCDMA) networks are proposed. The families are based in the three dimensional periodic Welch Costas array over elementary Abel
