General Method Based on Regressive Relationships to Parameterize the Three-Parameter Depth–Duration–Frequency Curve

نویسندگان

چکیده

This paper aims to present simple regressive equations estimate the parameters of three-parameter depth–duration–frequency (DDF) curve (3p-DDF), which accurately expresses, for a preassigned return period, relationship between rainfall depth and duration over large ranges, from below 1 h (i.e., tens minutes) above (up 24 h). These are developed relate their those two-parameter DDF (2p-DDF), can be estimated more easily being based on readily available data related durations h. In applications, first calibrated using recent pluviographic in northern Italy, Germany, Sweden. Two validation steps then carried out test terms depths same as used calibration step stations other geographic areas, i.e., Sicily southern past century, respectively. The results obtained prove this methodology capable providing reliable estimation short-duration rainfalls with various periods absence measurements fine temporal resolution.

on translation of phatic communion and socio-cultural relationships between the characters of the novels

phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...

Three-Phase to Single-Phase Matrix Converters: New Topology Based on New Control Method

In this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. In addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. In the proposed control metho...

A general method to speed up fixed-parameter-tractable algorithms

A fixed-parameter-tractable algorithm, or FPT algorithm for short, gets an instance (I, k) as its input and has to decide whether (I, k) ∈ L for some parameterized problem L. Many parameterized algorithms work in two stages: reduction to a problem kernel and bounded search tree. Their time complexity is then of the form O(p(|I|) + q(k)ξ), where q(k) is the size of the problem kernel. We show ho...
