5. Parameters of Hulls of Primitive BCH Codes of Length q3 – 1.

Author

Abstract

Let $\mathcal C_{(q,n,\delta)}$ be the primitive BCH code over $\Bbb F_{q}$ of length $n=q^{3}-1$ with designed distance $\delta $ , where $\Bbb F_{q}$ is the finite field of order $q$. In this letter, we investigate the parameters of the codes $\mathcal C_{(q, n, \delta)}$ and their hulls for $2 \le \delta \le n$. We also present a sufficient and necessary condition on the designed distance such that the hull has the largest dimension. [ABSTRACT FROM AUTHOR]

Abstract

University Town has specific set of characteristics (e.g. spatial distribution of building heights and structures, electrical equipment, highly dense human population) that determine the likelihood of lightning occurrence. In many cases the safety of faculty members, students, buildings and equipment is severely affected by lightning incident. However, regardless of its importance the research related to lightning occurrences is rather limited. Due to the limitation of the existing standards for risk assessment of lightning disaster, this paper will put forward a method, that based on the lightning location information, can potentially be used for risk assessment using statistical analysis of spatio-temporal distribution of lightning locations, occurrence frequency and corresponding intensities. In order to demonstrate the applicability of our method we apply the proposed algorithm to data gathered on the campus located in Pearl River Delta Region from 1999 to 2008.
