Weakest-link scaling is used in the reliability analysis of complex systems. It is characterized by the extensivity of the hazard function instead of the entropy. The Weibull distribution is the archetypical example of weakest-link scaling, and it describes variables such as the fracture strength of brittle materials, maximal annual rainfall, wind speed and earthquake return times. We investiga...

In this paper, a collocation method based on the Bernstein polynomials is presented for the fractional Riccati type differential equations. By writing t? ta (0 < a < 1) in the truncated Bernstein series, the truncated fractional Bernstein series is obtained and then it is transformed into the matrix form. By using Caputo fractional derivative, the matrix forms of the fractional derivatives are ...

This article aims to examine M-truncated soliton solutions of the fractional (4+1)-dimensional Fokas equation (FE), which is a generalization Kadomtsev-Petviashvili (KP) and Davey-Stewartson (DS) equations. The (4+1)$-dimensional with derivatives also studied first time in this study. generalized projective Riccati equations method (GPREM) successfully implemented. In application presented meth...

A Weibull analysis is presented of the dose and time relationships for the effects on 4080 inbred rats of chronic ingestion in the drinking water of 16 different doses of N-nitrosodimethylamine (NDMA) or N-nitrosodiethylamine (NDEA). The sites chiefly affected were the liver (by both agents) and the esophagus (by NDEA only). Since the experiment continued on into extreme old age, effects became...

In this paper we prove that the surface of the regular truncated tetrahedron can be triangulated into 10 non-obtuse geodesic triangles, and also into 12 acute geodesic triangles. Furthermore, we show that both triangulations have minimal size.

The Weibull distribution is a flexible statistical model for describing multipath fading channels in both indoor and outdoor radio propagation environments. A new closed-form expression is derived for the moment generating function of the Weibull distribution, valid when its fading parameter assumes integer values. The performance of digital linear modulations operating on Weibull channels is s...

This paper investigates the relationship between trade duration and liquidity of Chinese stock market. Using data of ten stocks, we employ a Weibull ACD model to decompose trade duration into two components: the expected and the unexpected duration. Then we analyze whether trade duration affects liquidity with regressions. We find that there exists a strong dependence between consecutive durati...

conclusions the results of the present study showed that the baculovirus expression system (sf9 cells) was able to express truncated orf2 and truncated orf2-nsp4 proteins as a potential candidate vaccine. background the hepatitis e virus (hev) accounts for hepatitis e infection with relatively high mortality rate in pregnant women that can lead to fulminant hepatitis. the baculovirus expression...
