In traditional scheduling problems, job processing times are considered constant and known in advance.This assumption is, however, a simplification when it comes to hand-intensive real-life production contexts because workers usually induce variability in the job processing times due to several factors such as learning, monotony, fatigue, psycholog
Abstract Human activity is increasingly and persistently disturbing nature and wild animals.Affected wildlife adopts multiple strategies to deal with different human influences.To explore 4 Pc. Sectional the effect of human activity on habitat utilization of Himalayan marmot (Marmota himalayana), habitat utilization patterns of three neighboring ma
Penetration and internal blast behavior of reactive liner enhanced shaped charge against concrete space were investigated through experiments and simulations.The volume of the enclosed concrete space is about 15 m3.The reactive liner enhanced shaped charge utilizes reactive copper double-layered liner, which rod seat adjustment is composed of an in
Models of the annual development cycle of trees in boreal and temperate regions were reviewed and classified on the basis of their ecophysiological assumptions.In our classification we discern two main categories of tree development: 1) fixed sequence development, which refers to irreversible Toslink ontogenetic development leading to visible pheno
Health assessment is an important part of PHM technology, which is crucial to product state monitoring and management.With the complexity of product structure and diversification of functions, the product health presents uncertainty under the complex influence of multiple factors.Nowadays, the general health assessment method is relatively simple a
