Aims: To determine the prevalence, patterns of occurrence and variations of zygomatic air cell defects (ZACDs) using panoramic radiographs.Methods and Scarves Materials: Dental panoramic radiographs of 600 outpatients were examined to evaluate the variations and characteristics of ZACDs.Results: ZACDs were identified in 15 subjects out of 600, givi
In this study, we propose a tightly coupled integrated method of ultrawideband (UWB) and light detection and ranging (LiDAR)-based simultaneous localization and mapping (SLAM) for global navigation satellite system (GNSS)-denied environments to achieve high-precision positioning with reduced drift.Specifically, we focus on non-line-of-sight (NLOS)
Numerous Tertiary to recent volcanoes are located in East Africa.Thus, much of the region is made up volcanic rock, which hosts Dress Shoes the largest and greatest variety of East Africas caves.Exploration of volcanic caves has preoccupied members of Cave Exploration Group of East Africa (CEGEA) for the past 30 years.The various publications edite
The sustained penetration of wind and solar generation is conducive to alleviating the energy crisis and environmental pollution.However, the finite capacity of transmission corridor limits the delivery of remote renewables and leads to curtailment.Energy storage plays an important role in renewables accommodation and improving equipment utilizatio
On the basis of the dam monitoring data,we analyze and evaluate dam deformation and dislocation distribution laws of spillway drain channels during operation upon the impounding of the face dam with crest overflow in Feigu Reservoir.The correlation analysis of environmental variables such as the reservoir water level,air temperature,and water tempe
