HEIGHT OF HYDRAULIC FRACTURE ZONE BASED ON PSO_LSSVM MODEL

Height of Hydraulic Fracture Zone Based on PSO_LSSVM Model

Predicting the height of water conducting fracture zones can prevent mine water damage and increase the upper sepia plex limit of mine mining.To achieve its effective prediction, this study selects four main control parameters for prediction, including the proportion coefficient of hard rock in the overlying strata, the inclination distance of the

Equivalence Ratio Effect on Helium Diluted Methane Jet Flame Temperature and Pollutant Emission for a Swirl Assisted Gas Turbine Burner

Temperature distribution and flue gas emissions in gas turbine combustion chambers have attracted the attention of researchers in recent years.In this study, the combustion chamber temperature distribution and flue gas emission values at different equivalence ratios were determined by diluting the methane flame with Helium at the rate of 20% by vol

Biopsy techniques for intraocular tumors

Biopsy involves the surgical removal of a tissue specimen for histopathologic evaluation.Most intraocular tumors are reliably diagnosed based on the clinical evaluation or with noninvasive diagnostic techniques.However, accurately diagnosing a small percentage of tumors can be challenging.A tissue biopsy is thus needed to establish a definitive dia
