This study processes an autonomous indoor drone photographer that searches for and selects a heuristic optimal viewpoint to obtain a well-composed photograph of a group of subjects.The subjects on the drone’s camera screen are represented by a Gaussian mixture model.When there are four or more subjects, they are represented by a Gaussian mix
A stepped pressure cycle is proposed to improve the energy efficiency of refrigeration and heat pump cycles.By constructing multiple suction and discharge pressures, the refrigerant Handbags temperatures in the evaporators and condensers underwent step changes and approached the heat source temperatures.This helps to improve heat transfer efficienc

The expansion of built environment is a major driver of land change which can have irreversible consequences on the environment, ecosystem services, and biodiversity.While most studies have focused on urban areas, particularly large cities, the built environment includes much more.This is exemplified by the complex interconnection among cities of a
Abstract Background Laparoscopic sleeve gastrectomy (LSG) has become an increasing bariatric procedure.The basic principle is to create a narrow stomach along the lesser curvature, using a calibration bougie as a template to perform a vertical partial gastrectomy, resecting the greater curvature and fundus of the stomach.The most common postoperati
