ABSTRACT Objectives To investigate the influence of attachment position and torque overcorrection on stress distribution tooth displacement trends during arch expansion in clear aligner therapy (CAT). Materials Methods Dental skeletal models were obtained from an adult volunteer with angle Class I mild crowding. Attachments designed buccal, lingual, buccolingual surfaces first molar. Different torques The whole analyzed using a three-dimensional finite element analysis model. Results Crown...
To reduce the data size of metric map and matching computational cost in unmanned ground vehicle self-driving navigation urban scenarios, a metric-topological hybrid system is proposed this paper. According to different positioning accuracy requirements, areas are divided into strong constraint (SC) areas, such as roads with lanes, loose (LC) intersections open areas. As direction provided by traffic lanes global waypoints road network, simple topological fit for SC While LC mainly relies on...
A design approach to triple-mode resonant feed antenna is advanced for parabolic reflector system. The composed of a slit-loaded 1.5-wavelength sectorial dipole, primary corner reflector, and an auxiliary circular reflector. angle the can be employed properly narrow down H-plane half-power beam width (HPBW), while with E-plane one rarely affected, such that equal E-/H-plane characteristic yielded accordingly. Unlike traditional backfire antennas, high-order modes are generate inverse taper...
The bullet shape is critical in efficient design because it affects the lift and drag forces. This paper proposes a new with logarithmic curve analyzes coefficients of bullets different curves under angles attack. results are compared whose described by power law curve. Fluent simulations demonstrate that optimal exponent values 0.65, 0.6, 0.65 for 1.3, 1, 1 at 0°, 30°, 40° attack, respectively. At 0° angle coefficient largest. force 129.4% higher than von Karman largest rectilinear curve;...
Abstract The number of new‐energy vehicles is steadily increasing worldwide, and joint refueling charging stations will be increasingly constructed developed in China. A CNG leakage at can lead to superimposed consequences, including fire (flash fire, pool jet fire), explosion, release toxic hazardous gases. Based on FLACS SAFETI, the impact aperture wind direction diffusion are analyzed by modeling a station Shaanxi, safe distance between piles points investigated worst case scenario....
The new spaceborne high resolution synthetic aperture radar (SAR) sensors on board the TerraSAR-X satellites can achieve spatial up to 1m. In SAR image, signature of urban buildings be identified and extracted. Due side-looking character SAR, building usually presents as L-shaped bright linear feature caused by two sides that facing sensor, while echoes from other sides' lost. It's clear multi aspect image will helpful for this problem. This paper deals with footprint extraction dual-aspect...
