the decomposition $gamma=bh$ of a group $gamma$ into a subset $b$ and a subgroup $h$ of $gamma$ induces, under general conditions, a group-like structure for $b$, known as a gyrogroup. the famous concrete realization of a gyrogroup, which motivated the emergence of gyrogroups into the mainstream, is the space of all relativistically admissible velocities along with a binary operation given by t...

Résumé. Dans cet article, nous proposons un système de classification des comptes-rendus mammographiques, reposant sur une ontologie radiologique décrivant les signes radiologiques et les différentes classes de la classification ACR des systèmes BIRADS dans le langage OWL. Le système est conçu pour, extraire les faits issus des textes libres de comptes-rendus en étant dirigé par l’ontologie, pu...

Abstract In this paper, mono-metallic catalysts, palladium (Pd) and gold (Au) bi-metallic, Au-Pd supported on reduced graphene oxide (rGO) synthesized by Sol Immobilization technique. The as fabricated catalysts (Pd/rGO, Au/rGO Au-Pd/rGO) have been tested various techniques (Raman Spectroscopy, FE-SEM, XRD TEM) to examine the structural, compositional morphological characteristics. performance ...

Bi-layer metallic tube (BMT) plays an extremely crucial role in engineering applications, with rotary draw bending (RDB) the high-precision processing can be achieved, however, product will further springback. Due to complex structure of BMT and high cost dataset acquisition, existing methods based on mechanism research machine learning cannot meet requirements springback prediction. Based prel...

Hot-dip galvanization is a common corrosion-prevention technique for steel structures. The submerged in molten zinc bath, which forms coating on the steel’s surface. This provides barrier against corrosive elements. However, galvanized covering can still deteriorate, especially harsh environments. As consequence, several studies have been conducted to improve corrosion resistance of by adding m...

Bi-layer lift-off metallization techniques offer significant advantages in resolution, removal, process simplicity, undercut control and yield over conventional single-layer lift-off processes. Because of its ease of application, long shelf life and lower tool cost, the polydimethylglutarimide (PMGI) bi-layer process has become an attractive method for the metallization of III-V compound semico...
