Stochastic order relations among parallel systems from Weibull distributions [PDF]

open access: yes, 2014
In this article, we focus on stochastic orders to compare the magnitudes of two parallel systems from Weibull distributions when one set of scale parameters majorizes the other. The new results obtained here extend some of those proved by Dykstra et al. (

Modelación de distribuciones novedosas para la representación del Clutter de Radar

open access: yesEntramado, 2017
El clutter es una señal interferente causada por la reflexión de la emisión del radar sobre la superficie que rodea al blanco. Tradicionalmente, se han utilizado las distribuciones K, Weibull, Log-Normal, Rayleigh y Pareto para representar el ...

Aerodynamic Optimization of Trailing-Edge-Serrations for a Wind Turbine Blade Using Taguchi Modified Additive Model

open access: yesEnergies, 2023
For the rotor, achieving relatively high aerodynamic performance in specific wind conditions is a long-term goal. Inspired by the remarkable flight characteristics of owls, an optimal trailing edge serration design is investigated and proposed for a wind

Scaling in the distribution of intertrade durations of Chinese stocks [PDF]

open access: yes, 2008
The distribution of intertrade durations, defined as the waiting times between two consecutive transactions, is investigated based upon the limit order book data of 23 liquid Chinese stocks listed on the Shenzhen Stock Exchange in the whole year 2003.

Teaching Policy Instrument Choice in Environmental Law: The Five P’s [PDF]

open access: yes, 2013
. We introduce a method to combine the color channels of an image to a scalar valued image. Linear combinations of the RGB chan-nels are constructed using the Fisher-Trace-Information (FTI), defined as the trace of the Fisher information matrix of the ...

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...
