Balanced reduction method of direct-drive wind farm for subsynchronous oscillation analysis
电力工程技术, 2023 Direct-drive wind farms (DDWF) merged into weak AC systems have the risk of sub-synchronous oscillations (SSO). Because the DDWF model has a higher order, it needs to be reduced for actual analysis.

Recent Applications of Molecular Structures at Silicon Anode Interfaces
Electrochem, 2021 Silicon (Si) is a promising anode material to realize many-fold higher anode capacity in next-generation lithium-ion batteries (LIBs). Si electrochemistry has strong dependence on the property of the Si interface, and therefore, Si surface engineering ...

Reliable Distributed Storage [PDF]
Computer, 2009 A distributed storage service lets clients abstract a single reliable shared storage device using a collection of possibly unreliable computing units. Algorithms that implement this abstraction offer certain tradeoffs and vary according to dimensions such as complexity, the consistency semantics provided, and the types of failures tolerated.

Distributed storage in the plane [PDF]
2014 IFIP Networking Conference, 2014 We consider storage devices located in the plane according to a general point process and specialize the results for the homogeneous Poisson process. A large data file is stored at the storage devices, which have limited storage capabilities. Hence, they can only store parts of the data.

Alleviating oxygen evolution from Li-excess oxide materials through theory-guided surface protection
Nature Communications, 2018 Rechargeable Li-ion batteries can show extensive oxygen loss from the cathode material under operating conditions. Here, the authors use high-throughput computational screening to guide the synthesis of a Tantalum-doped Li-excess cathode that ...
