On the Stopping Distance of SA-LDPC Codes by Transversal Designs

open access: yesIEEE Access, 2018
In this paper, we analyze the size of the smallest stopping set (called the stopping distance) for the parity-check matrix of a superposed array low-density parity-check (SA-LDPC) code for column weights 3 and 4 by using the transversal design (TD ...

The Principles of Design for Vulnerable Communities: A Research by Design Approach Overrunning the Disciplinary Boundaries

open access: yesBuildings, 2022
Current changes are making communities, cities, and territories increasingly vulnerable. Urban architectural interventions have the power to intervene this situation, directly reducing vulnerabilities or backing social initiatives.

Embeddable transversal designs

open access: yesDiscrete Mathematics, 1980
The embeddability of certain (group) divisible designs in symmetric 2-designs is investigated. These designs are symmetric resolvable transversal designs. It is proved that all such transversal designs with v = 2k are embeddable and some necessary and sufficient conditions for other cases are given.

A Transversal Analysis of Different Learning Design Approaches

open access: yesJournal of Interactive Media in Education, 2008
The goal of the ICALT workshop "Comparing Educational Modelling* Languages on a Case Study" was to compare different Learning Design approaches. Various teams were asked to design and implement a common case study and to answer common given challenges ...

On the number of transversal designs

open access: yesJournal of Combinatorial Theory, Series A, 2013
Bounds are obtained on the number of distinct transversal designs TD(g, n) (having g groups with n points in each group) for certain values of g and n. Amongst other results it is proved that, if 2 < g ≤ q + 1 where q is a prime power, then the number of nonisomorphic TD(g, ) designs is at least qαrq2r(1-o(1)) as r → ∞ , where α = 1/.

Transversal Designs and Doubly-resolvable Designs

open access: yesEuropean Journal of Combinatorics, 1980
A problem which has recently attracted much interest is to arrange the blocks of a (v, k, 1)-BIBD into some of the cells of a square array such that each element of the design occurs in precisely one cell of each row and column of the array. For k = 2, the problem has been completely settled.

Dual-Polarization and Dual-Band Conical-Beam Array Antenna Based on Dual-Mode Cross-Slotted Cylindrical Waveguide

open access: yesIEEE Access, 2021
Two designs of conical-beam array antennas are presented for different fifth-generation applications. They are based on slotted cylindrical waveguides and a travelling-wave topology, where the waveguide is used to progressively excite a cross-slot array.

A new pooling strategy for high-throughput screening: the Shifted Transversal Design

open access: yesBMC Bioinformatics, 2006
Background In binary high-throughput screening projects where the goal is the identification of low-frequency events, beyond the obvious issue of efficiency, false positives and false negatives are a major concern. Pooling constitutes a natural solution:
