An Antenna-Theory Method for Modeling High-Frequency RF Coils: A Segmented Birdcage Example by Xin Chen, Victor Taracila, Timothy Eagan, Hiroyuki Fujita, Xingxian Shou, Tanvir Baig, Robert Brown

“…As a byproduct, it is shown that for a long single-segmented birdcage model, the RF field within it is essentially a TEM mode and has excellent planar uniformity. For a short shielded multisegmented birdcage model, the RF field is optimized with a target-field approach with an average SAR functional. …”

Ontology-Based Resource Modeling and Matching Framework in Avionics Systems by Xiaoyan Du, Chenglie Du, Jinchao Chen, Chunhui Dong, Yifan Liu

“…First, this paper constructs a hierarchical resource organization framework based on virtual resource pool, covering dispersed and heterogeneous avionics resources and shielding the differences and diversity of resources; next, introduces ontology technology into resource modeling and encapsulates resources as services using the idea of “resource as a service,” facilitating the access and control of resources; in addition, proposes a matching framework which takes into account the energy consumption, in which it firstly tries to find a list of resources which can meet task requirements by a stepwise intelligent matching strategy based on semantic similarity, and the resources in the list will then be sorted according to the energy consumption. …”

Marquage héraldique, cartographie et histoire des lignages : les relevés de Gaignières à la chapelle des chanoinesses de Luynes by Sarah Héquette

“…Judging by the drawings they made on the spot, Gaignières’ interest in the building lay in its profusion of symbols: six of Louis Boudan’s ten drawings focused on the heraldry of the families who had left their mark on the place. In all, twelve shields, made up of fifteen different quarters, were copied by Gaignières and bear witness to the filiation, alliances and genealogy of the Maillé family. …”
