In order to solve the problem of reflection cracks in semi-rigid base asphalt pavement, a study of temperature-type reflection crack expansion is carried out according to the typical climatic characteristics of Guilin, Guangxi Province.According to the theory of fatigue fracture mechanics, the stress intensity factor analysis at the crack tip is ca
This paper proposes a direct sinogram correction method Picture Frame Light Box that does not require metal segmentation and prior knowledge to reduce metal-related artifacts in polychromatic computerized tomography (CT).The metal-related artifacts, being common in dental conebeam CT images, are caused by beam hardening-induced sinogram inconsisten
The aim of the Metallophone paper is to experimentally measure and ealuate bulk modulus of oil/steel pipe system and oil/hose system.The measurement was performed using experimental device on the basis of a measured pressure difference depending on time.Bulk modulus is evaluated from pressure change with known flow and volume of line.Pressure rise
In a more connected world than ever, with an expanding global market, old businesses that once used to dominate the markets found themselves facing big problems when new business models emerged, when the internet led to the birth of e-commerce and different kinds of shopping channels and experiences.Globalization proved to be helpful for those who
Recently, interest in ultrawideband (UWB)-based localization systems has increased in various application fields.However, since UWB anchors are usually fixed, they work only within the limited range that UWB measurement signals can reach.To address this issue, a swarm flight system with movable UWB anchors is developed.One ground station controls m
