Amid advancements in aerospace technology and SWEATERSTURTLENECK remote communication, a proliferation of Earth-observing satellites has been launched, creating a distinction between high- and low-altitude platforms.High-altitude satellites capture low-resolution (LR) aerial images, covering expansive areas, whereas their low-altitude counterparts
An Automatic Key-Frame Selection Method for Monocular Visual Odometry of Ground Vehicle
In response to the rapid change of attitude in complex situations such as sharp turns and camera jitter, visual odometry/visual simultaneous localization and mapping (VO/VSLAM) often requires a high camera frame rate.However, the high frame rate of the camera poses a great challenge to real-time VO/VSLAM, especially when the vehicle travels along a
Congenital atresia of the ostium of the left coronary artery. Diagnostic difficulty and successful surgical revascularization in two patients
We report two cases of congenital atresia of the ostium of the left coronary artery.Case 1: a six-month-old infant presenting with serious cardiac insufficiency.A noninvasive diagnosis of dilated myocardiopathy was established and the clinical picture was pharmacologically compensated.When the patient was nine months of age, a hemodynamic study was
Enhancement of Vibration Energy Harvesting Performance by Omni-Directional INVELOX Wind Funnel: A Computational Study
An alternate renewable energy source, through a piezoelectric vibration energy harvester with a bluff splitter body, could lead to higher efficiency in energy harvesting, through vortex-induced vibration at a near-resonance condition at 20 m/s high wind speed.However, wind energy is Art by Venue not as popular as solar energy, as the main renewable
