Multi-port energy routers are a core device that integrates distributed sources and enables energy-to-energy interconnections. For the routing system, construction of its topology, establishment internal model switching control common bus voltage stability key elements research. In this paper, five-port router structure is proposed, including PV port, an storage grid-connected DC load AC port. ...

In both developed and developing countries, port-city relationships have always attracted much attention. However, in the port–city interface, views differ as to whether port drives city or vice versa. The combination of remote sensing data geospatial big (point interest) has provided a favorable solution. Taking typical estuarine coastal cities China’s zone an example, this study examines foll...

Abstract Port‐Hamiltonian systems provide an energy‐based formulation with a model class that is closed under structure preserving interconnection. For continuous‐time systems, these interconnections are constructed by geometric objects called Dirac structures. In this paper, we derive and the interconnection properties for scattering passive discrete‐time port‐Hamiltonian systems.

The performance of zeolites as solid acid catalysts is strongly influenced by the accessibility of active sites. However, synthetic zeolites typically grow as complex aggregates of small nanocrystallites rather than perfect single crystals. The structural complexity must therefore play a decisive role in zeolite catalyst applicability. Traditional tools for the characterization of heterogeneous...

An investigation of non-linear ballistic transport is being conducted, two device structures are investigated, a ballistic deflection transistor and a t-junction device. The transistor structure demonstrates a novel device that produces large small-signal gains in excess of 150. The t-junction structure was used to investigate the impact of ballistic transport versus upper valley transfer. A ba...

peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...

Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...
