Waist-to-height ratio is a simple tool for assessing central obesity and consequent health risk
(2023-09-26)Since the dawn of the study of the human figure (shape and dimensions), science has consistently made progress in establishing its connection to health and physiologic homeostasis. In Vitruvius’ Ten Books of Architecture ... -
Water and carbon dynamics in an arid playa of the Chihuahuan Desert
(2023-12-11)Ephemeral playas are unique landscapes found in arid and semiarid regions around the world. These lakebeds are often characterized by flat, grassy expanses that may be covered with salt crusts. Playas are formed in closed ... -
Water conservation potential of modified turf grass irrigation in urban parks of Phoenix, Arizona
(2022-04-28)Large amounts of water are consumed by urban parks in arid regions such that efficient irrigation practices are needed. In Phoenix, Arizona, extensive turf grass areas are supported using flood or sprinkler irrigation that ... -
WATER-USE EFFICIENCY IN SEMI-ARID ECOSYSTEMS OF NORTHERN MEXICO
(2023-12-11)Arid and semi-arid ecosystems represent 45% of the world's terrestrial ecosystems and 60% of Mexico's land surface. These regions play an important role in the global C sink variability, due to their response to water ... -
Weibull Analysis for Constant and Variant Stress Behavior Using the Alt Method for Single Stress and the Taguchi Method for Several Stress Variables
(2018-04)The article presents the advances on Weibull analysis which let practitioners to plan the data collection test, to fit the Weibull parameters directly from the applied stress values, to determine the capability indices cp ... -
Weibull analysis for normal/accelerated and fatigue random vibration test
(2019-05-16)In this paper, the formula to estimate the sample size n to perform a random vibration test is derived only from the desired reliability (R(t)). Then, the addressed n value is used to design the ISO16750‐3 random vibration ... -
Weibull Reliability Method for Several Fields Based Only on the Modeled Quadratic Form
(Taylor & Francis, 2021-09-24)In this chapter, a practical and dynamic method to determine the reliability of a process (or product) is presented. The novelty of the proposed method is that it let us to use the Weibull distribution to determine the ... -
Weibull Reliability Methodology for Ball Bearing Design Based on Hertz Stress With Focus on Industry 4.0
