Abstract

A 3-phase Barker array is a matrix of third roots of unity for which all out-of-phase aperiodic autocorrelations have magnitude 0 or 1. The only known truly two-dimensional 3-phase Barker arrays have size 2 × 2 or 3 × 3. We use a mixture of combinatorial arguments and algebraic number theory to establish severe restrictions on the size of a 3-phase Barker array when at least one of its dimensions is divisible by 3. In particular, there exists a double-exponentially growing arithmetic function T such that no 3-phase Barker array of size [ABSTRACT FROM AUTHOR]

118. Z4-Valued Quadratic Forms and Quaternary Sequence Families.

Abstract

In this paper, 74-valued quadratic forms defined on a vector space over GF(2) are studied. A classification of such forms is established, distinguishing Z4-valued quadratic forms only by their rank and whether the associated bilinear form is alternating. This result is used to compute the distribution of certain exponential sums, which occur frequently in the analysis of quaternary codes and quaternary sequence sets. The concept is applied as follows. When t = 0 or m is odd, the correlation distribution of family S (t), consisting of quaternary sequences of length 2m - 1, is established. Then, motivated by practical considerations, a subset S* (t) of family S (t) is defined, and the correlation distribution of family S* (t) is given for odd and even m. [ABSTRACT FROM AUTHOR]

119. A risk-risk assessment framework for solar radiation modification

Abstract

Concern about the increasingly high-probability, high-impact risks posed by global warming is driving the exploration of new techniques to artificially cool the planet through an approach known as solar radiation modification (SRM). Would the world be better off with or without such techniques? Would there be winners and losers? And how can we sufficiently compare the relative risks presented in a future with SRM against the risks faced in a future without it? Such ‘risk-risk’ assessment poses particular challenges given uncertainties around the techniques and the extent of human-induced changes to the climate system that might be expected in the future. These uncertainties are further compounded by differences in stakeholders’ framing and risk tolerance, as well as the level of complexity and the intertemporal nature of such assessment. To help address these questions, mindful of such challenges, we present here a basic risk-risk assessment framework providing a structure to help strengthen risk-management considerations in the design of future climate response strategies.

146. Pairwise balanced designs related to Periodic Golay pairs

Author

Crnković, Dean, Dumičić Danilović, Doris, Egan, Ronan, Švob, Andrea, Schmidt, Kai-Uwe, and Steffen, Eckhard

Subjects
Pairwise balanced design, Periodic Golay pair, Hadamard matrix, automorphism group
Abstract

In this talk we give a relation between certain pairwise balanced designs (PBDs) with v points and periodic Golay pairs (PGPs) of length v. Using this connection, we classify PGPs of length less than 40 and construct new PGPs of lengths greater than 40 where classifications remain incomplete. Further, we show that under certain conditions the incidence and orbit matrices of PBDs related to PGPs span quasi-cyclic self-orthogonal codes.
