This paper develops an efficient new method for 3D partial shape retrieval. First, a Monte Carlo sampling strategy is employed to extract local signatures from each model. After vector quantization, these features are represented by using bag-of-words The main contributions of this threefold as follows: 1) dissimilarity measure proposed rank shapes according their distances the input query, without any timeconsuming alignment procedure; 2) applying probabilistic text analysis technique,...
Abstract Objective: To determine the accuracy of volumetric analysis teeth in vivo using cone-beam computed tomography (CBCT). Materials and Methods: The physical volume (Vw) 24 bicuspids extracted for orthodontic purposes (16 were imaged with I-CAT 8 CB MercuRay) determined water displacement technique. Corresponding pretreatment CBCT image data uploaded into Amira 4.0 segmentation radiographic (Va). All measurements performed twice by two observers. statistical difference between Vw Va was...
Advanced high-strength steels (AHSS) have revolutionized the automotive industry by reducing weight without compromising crashworthiness. The new third-generation steels, such as quenching and partitioning (QP) offer exceptional strength ductility. However, despite extensive strength-ductility studies, there is a wide knowledge gap in literature on fracture behavior of QP under large range stress states loading conditions for material forming operations. This study aims to systematically...
The East Kunlun Orogenic Belt (EKOB), which is in the northern part of Greater Tibetan Plateau, contains voluminous Late Triassic intermediate-felsic volcanic rocks. In east end EKOB, we identified highly differentiated peralkaline-like Xiangride rhyolites (~209 Ma) that differ from widespread andesitic-rhyolitic Elashan volcanics (~232–225 terms their field occurrences and mineral assemblages. older, more common calc-alkaline felsic may have originated partial melting underthrust...
The river is one of the most important freshwater ecosystems serving as a hub for water, gas, and energy exchange among land, ocean, and atmosphere. River ecosystem metabolism vibrates with external stresses such solar radiation, flow stability, temperature. We discovered that internal factor dissolved inorganic carbon (DIC) plays hidden role in amplifying riverine metabolic sensitivity, which, however, is rarely concerned. In...
In an attempt to overcome the limitations of titanium in dental and orthopaedic clinical applications, a new method has been developed prepare calcium carbonate coatings on sandblasted acid-etched (SA) implants. The purpose this study was investigate effect carbonate-SA (CC-SA) implants osseointegration vivo. surfaces SA CC-SA were characterised for surface morphology chemistry. Subsequently, these two kinds implanted femoral condyles rabbits. retrieved prepared histological...
Laser-assisted forming provides a perfect solution that overcomes the formability of low-ductility materials. In this study, laser-assisted robotic roller (LRRF) was applied to bend ultrahigh-strength steel sheet (a quenching and partitioning with strength grade 1180 MPa), effects laser power density on bending forces, springback, radius final parts were investigated. The results show LRRF is capable reducing forces by 43%, compact profile high precision (i.e., springback angle smaller than...
