HYPER (HYbrid Power Extraction Reactor) is the accelerator-driven transmutation system developed by KAERI (Korea Atomic Energy Research Institute). HYPER is designed to transmute long-lived transuranic actinides and fission products such as Tc and I. HYPER adopts a fast neutron system and Pb-Bi is used as core coolant and target material. Pb-Bi corrosion is one of the main factors considered to...

We theoretically demonstrate the formation of multiple bi-stability regions in the temperature pattern on the interface between a cuprous oxide quantum well and DCM2:CA:PS organic compound. The Frenkel molecular exciton of the DCM2 is brought into resonance with the 1S quadrupole Wannier-Mott exciton in the cuprous oxide by ”solvatochromism” with CA. The resulting hybrid is thermalized with sur...

This paper presents and investigates different approaches to solve a new biobjective routing problem called the ring star problem. It consists of locating a simple cycle through a subset of nodes of a graph while optimizing two kinds of cost. The first objective is the minimization of a ring cost that is related to the length of the cycle. The second one is the minimization of an assignment cos...

This paper focuses on the study of MAC protocol in industrial wireless ad-hoc network, aiming at improving the fairness of industrial wireless ad-hoc network and quality of service (QOS). As a result, Hybrid Bi-channel Improvement of CSMA/CA mechanism and Dynamic Time Slot of TDMA mechanism MAC (B-T-MAC) is proposed. This protocol using the super frame structure, adopts the methods of bi-channe...

In this study, the tensile and compressive behaviors of pure and hybrid composite laminates reinforced by basalt–nylon bi-woven intra-ply fabrics were experimentally investigated. Epoxy resin was used as the matrix material. The purpose of using this hybrid composite is to obtain superior characteristics by using the good strength property of basalt fiber with the excellent toughness of ny...

Oxide-free bonding of III-V-based materials for integrated optics is demonstrated on both planar Silicon (Si) surfaces and nanostructured ones, using Silicon on Isolator (SOI) or Si substrates. The hybrid interface is characterized electrically and mechanically. A hybrid InP-on-SOI waveguide, including a bi-periodic nano structuration of the silicon guiding layer is demonstrated to provide wave...

This paper addresses the issue of integrating top-down and bottom-up processing of information in modular hybrid systems. Backed by computational and neurological evidence, we show that there are important advantages to be gained from supporting bi-directional flow of information, especially in the context of intelligent information processing in real-world applications. We consider modular hyb...

First-principles calculations based on density functional theory have been performed for the quaternary GaAs1-x-y N x Bi y alloy lattice-matched to GaAs. Using the state-of-the-art computational method with the Heyd-Scuseria-Ernzerhof (HSE) hybrid functional, electronic, and optical properties were obtained, including band structures, density of states (DOSs), dielectric function, absorption co...
