A novel current-limiting hybrid DC breaker based on thyristors
Energy Reports, 2023 Since the DC current has no zero-crossing in high-voltage and large-capacity DC scenarios, and the low line impedance results in a large growth rate of fault current, the breaking requirements of DC circuit breakers (DCCB) are further increased.

Breaking through the Full-Duplex Wi-Fi capacity gain [PDF]
2016 7th International Conference on the Network of the Future (NOF), 2016 In this work we identify a seminal design guideline that prevents current Full-Duplex (FD) MAC protocols to scale the FD capacity gain (i.e. 2x the half-duplex throughput) in single-cell Wi-Fi networks. Under such guideline (referred to as 1:1), a MAC protocol attempts to initiate up to two simultaneous transmissions in the FD bandwidth.

Line-of-Sight MIMO in Point-to-Point Millimeter Wave Links via Scattering From Rough Surfaces
IEEE Access, 2023 We analyze a point-to-point MIMO communication system over a deterministic channel with two paths: line-of-sight (LoS) and a scattered path over a rough surface.

Influencing Factors of Breaking Capacity of Double-Break Vacuum Circuit Breakers
TELKOMNIKA Indonesian Journal of Electrical Engineering, 2013 Using a series arrangement of two vacuum interrupters (VIs) has been proved to be an effective way of developing higher voltage vacuum circuit breakers (VCBs), which are known as double-break VCBs. The uniform distribution of the transient recovery voltage (TRV) across each VI is very critical for the breaking capacity of double-break VCBs.

Strong converse for the classical capacity of entanglement-breaking and Hadamard channels via a sandwiched Renyi relative entropy [PDF]
, 2014 A strong converse theorem for the classical capacity of a quantum channel states that the probability of correctly decoding a classical message converges exponentially fast to zero in the limit of many channel uses if the rate of communication exceeds ...

Directional current breaking capacity requirements for HVDC circuit breakers [PDF]
2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015 Circuit breakers are expected to be a vital element within any high capacity HVDC network. This paper examines the directional current breaking capacity requirements that might be seen on a typical HVDC grid, as required for the specification of backup protection.
