Design and Vertical Tests of SPS-series Double-Quarter Wave (DQW) Cavity Prototypes for the HL-LHC Crab Cavity System

open access: yes, 2018
Crab crossing is essential for high-luminosity colliders. The High Luminosity Large Hadron Collider (HL-LHC) will equip one of its Interaction Points (IP1) with Double-Quarter Wave (DQW) crab cavities.

Turn-to-turn fault protection technique for synchronous machines without additional voltage transformers [PDF]

open access: yes, 2017
This paper presents a novel protection technique for the detection of inter-turn faults in synchronous machines. It is based on the calculation of voltage in the stator windings from the usual phases and neutral voltage, typically available in ...

Shot noise and conductivity at high bias in bilayer graphene: Signatures of electron-optical phonon coupling [PDF]

open access: yes, 2011
We have studied electronic conductivity and shot noise of bilayer graphene (BLG) sheets at high bias voltages and low bath temperature $T_0=4.2$ K. As a function of bias, we find initially an increase of the differential conductivity, which we attribute ...

Hydrophobic residues in S1 modulate enzymatic function and voltage sensing in voltage-sensing phosphatase

open access: yesJournal of General Physiology
The voltage-sensing domain (VSD) is a four-helix modular protein domain that converts electrical signals into conformational changes, leading to open pores and active enzymes. In most voltage-sensing proteins, the VSDs do not interact with one another, and the S1–S3 helices are considered mainly scaffolding, except in the voltage-sensing phosphatase ...

Singular conductance of a spin 1 quantum dot

open access: yes, 2004
We interpret the recent observation of a zero-bias anomaly in spin-1 quantum dots in terms of an underscreened Kondo effect. Although a spin-1 quantum dots are expected to undergo a two-stage quenching effect, in practice the log normal distribution of ...

Robust Matrix Completion State Estimation in Distribution Systems

open access: yes, 2019
Due to the insufficient measurements in the distribution system state estimation (DSSE), full observability and redundant measurements are difficult to achieve without using the pseudo measurements.

Optimization Method for Combination of Residual Current Protection and Coincidence Brake Logic in a Low-Voltage Distribution System

open access: yesShanghai Jiaotong Daxue xuebao
Low-voltage distribution systems frequently experience leakage current accidents. However, it is challenging to distinguish fault characteristics in abnormal operating conditions, such as electric shock to biological organisms and three-phase imbalance ...
