hershfield method is commonly used for computing probable maximum precipitation (pmp) in most parts of the world for which the frequency factor (km) is considered to be 15 for computing 24-h pmp (pmp24). this value may not be suitable for different stations under different climatic conditions. in 1986 the world meteorological organization standardized the hershfield method and introduced the re...

Here in this paper, we establish sharp bounds on the expectations of k record increments from general and non-negative parent distributions. We also determine the probability distributions for which the bounds are attained. The bounds are numerically evaluated and compared with other rough bounds.

A binary split tree is a search structure combining features of heaps and binary search trees. Building an optimal binary split tree was originally conjectured to be intractable due to di culties in applying dynamic programming techniques to the problem. However, two algorithms have recently been published which generate optimal trees in O(n5) time, for records with distinct access probabilitie...

Abstract We consider the standard and k th record values arising in sequences of independent identically distributed continuous positive random variables with finite expectations. determine necessary sufficient conditions on type , its number n moment order r so that value is for every parent distribution. Under we present optimal upper bounds these moments expressed scale units being respectiv...

Many negative δ(13)C excursions in marine carbonates from the geological record are interpreted to record significant biogeochemical events in early Earth history. The assumption that no post-depositional processes can simultaneously alter carbonate and organic δ(13)C values towards more negative values is the cornerstone of this approach. However, the effects of post-depositional alteration on...

1. APPROXIMATE TOP-K Let {e1, e2, . . . , el} be a set of distinct records in a database, with unique IDs {id1, id2, . . . , idl}. Let A1, A2, . . . , Ap be a set of distinct attributes for each record. For every record ei, the attribute Aj is zero or some positive value. We denote the value of the attribute Aj of record ei by Aj(ei). The sum of the attributes of ei is denoted by Ni = ∑ j Aj(ei...

This paper address the problem of Bayesian estimation of the parameters, reliability and hazard function in the context of record statistics values from the two-parameter Lomax distribution. The ML and the Bayes estimates based on records are derived for the two unknown parameters and the survival time parameters, reliability and hazard functions. The Bayes estimates are obtained based on conju...
