Trend prediction of greenhouse microclimate is crucial, as crops are vulnerable to potential losses resulting from dramatic changes in microclimate. Consequently, a precise predictive model required that can predict trends microclimates several weeks advance avoid financial losses. In the present study, we proposed hybrid ensemble approach based on an Informer optimized using improved empirical...

cucumbers grown under open air conditions, encounters chilling damages, during cold seasons. plastic tunnels provide suitable heat environment for growing cucumber. the objective of this research was to evaluate cucumber phonological stages and leaf area expansion within three different plastic tunnel microclimates to moderate air temperature and air humidity. three microclimates including 1. c...

The apoplastic pH of intact Forsythiaxintermedia (cv. Lynwood) and tomato (Solanum lycopersicum) plants has been manipulated using buffered foliar sprays, and thereby stomatal conductance (g(s)), leaf growth rate, and plant water loss have been controlled. The more alkaline the pH of the foliar spray, the lower the g(s) and/or leaf growth rate subsequently measured. The most alkaline pH that wa...

The pure physical approach used to characterise thermal comfort is not informative for many urban designers and landscape architects. Significantly, this theoretical approach was criticised due to the lack of consideration of human sensations ad perceptions. Recent researches show an increased consideration for psychological and behavioural aspects of outdoor thermal comfort. However, the epist...

the performance of water flooding can be investigated by using either detail numerical modeling or simulation, or simply through the analytical buckley-leverett (bl) model. the buckley-leverett analytical technique can be applied to one-dimensional homogeneous systems. in this paper, the impact of heterogeneity on water flooding performance and fractional flow curve is investigated. first, a ba...

Let $mathbb{F}$ be an algebraically closed field of prime characteristic $p>2$ and $(g, [p])$ a finite-dimensional restricted Lie superalgebra over $mathbb{F}$. It is showed that anyfinite-dimensional indecomposable $g$-module is a module for a finite-dimensional quotient of the universal enveloping superalgebra of $g$. These quotient superalgebras are called the generalized reduced enveloping ...

a closed form three-dimensional solution is presented for determination of the local buckling (cell buckling) load of the nanosheets. moreover, an expression is proposed for the effective 2d young’s modulus of the unit cell of the nanosheet. in this regard, a three-dimensional efficient space-frame-like geometrical model with angular and extensional compliances is considered to investigate stab...

Due to the complexity of built environment, urban design patterns considerably affect the microclimate and outdoor thermal comfort in a given urban morphology. Variables such as building heights and orientations, spaces between buildings, plot coverage alter solar access, wind speed and direction at street level. To improve microclimate and comfort conditions urban design elements including veg...
