This study aims to propose a kinetics-based model of fatigue crack growth rate coupling with temperature, strain level and damage degree for bituminous materials. The length is calculated by an energy-based mechanistic (EBM) approach, kinetic parameters characterizing the are determined based on Arrhenius equation. Results show that logarithm linear inverse absolute cracking activation energy i...

The Coronavirus disease (Covid-19) has become a global problem since WHO declared pandemic in 2020. number of deaths due to Covid-19 increased significantly many countries. This study aimed implement decision tree modeling represent the relationship between risk factors and mortality rate patients. analyzed secondary data 83,024 Covid patients from January 2020 June 2021. Data processing used m...

The software reliability model is the stochastic to measure quantitatively. A Hazard-Rate Model well-known one as typical model. We propose Models Considering Fault Severity Levels (CFSL) for Open Source Software (OSS). purpose of this research make considering CFSL adapt baseline hazard function and 2 kinds faults data in Bug Tracking System (BTS), i.e., we use covariate vectors Cox proportion...

A model of a rigid-plastic rate-independent polycrystalline aggregate wherein subaggregates are represented as the nodes of a binary tree is proposed. The lowest nodes of the binary tree represent grains. Higher binary tree nodes represent increasingly larger sub-aggregates of grains, culminating with the root of the tree, which represents the entire polycrystalline aggregate. Planar interfaces...

represented by a set of fbg filters each corresponding to a resonance peak where f is the formant frequency, b the 3 dB bandwidth and g the gain of a resonant peak. Speech coding algorithms are basic components in existing and future personal communication systems. Reducing the bit rate in transmitting speech is by way a matter of using slowly varying and numerical robust parameters to represen...
