OPTIMIZATION DESIGN OF HORIZONTAL WELL FRACTURE STAGE PLACEMENT IN SHALE GAS RESERVOIRS BASED ON AN EFFICIENT VARIABLE-FIDELITY SURROGATE MODEL AND INTELLIGENT ALGORITHM

Hydraulic fracturing technique increases shale gas well productivity significantly.Horizontal well fracture optimization has been studied by many researchers worldwide in the past decade.However, most of these researches relied on computationally expensive numerical simulation models for objectives evaluation during the optimization process.This af

In recent years, developing target detection algorithms has received growing interest in hyperspectral images.In comparison to the classification field, few studies have been done on dimension reduction or band selection Earthrise for target detection in hyperspectral images.This study presents a simple method to remove bad bands from the images in

Objective: The current investigation examined the efficacy of palliative care in alleviating death anxiety, enhancing self-compassion, and mitigating perceived stress among patients diagnosed with leukemia.Methods: This study was executed following an experimental design that included both a control group and an experimental group across pre-test a

The main objective of this study is the identification of major factors controlling levels and chemical composition of aerosols in the regional background (RB) along the Mediterranean Basin (MB).To this end, data on PM levels and speciation from Montseny (MSY, NE Spain), Finokalia (FKL, Southern Greece) and Erdemli (ERL, Southern Turkey) for the pe

Scientific evidence is not clear regarding the use of antimicrobial mouth rinse before dental extraction to reduce bacteremia.We tested the null hypothesis that there would be no Safety and Hazard Lighting difference in the incidence of bacteremia following dental extractions in patients treated with or without chlorhexidine.We conducted a meta-ana
