Transient voltage stresses in MMC–HVDC links – impulse analysis and novel proposals for synthetic laboratory generation

High Voltage, 2018
To evaluate and optimise insulation coordination concepts for state of the art high-voltage direct current (HVDC) transmission systems, appropriate test voltage shapes are required for laboratory imitation of occurring stresses.

Research on 3‐D total electric field of crossing high voltage direct current transmission lines based on upstream finite element method

High Voltage, 2021
The ongoing large‐scale construction of ultra high voltage direct current projects in China makes the crossing of two high voltage direct current (HVDC) lines inevitable.

Voltage Graphs

Discrete Mathematics, 1974
AbstractA possible way to obtain a complicated graph imbedding in a surface is to derive it as a covering of a simpler imbedding by assigning “voltages” to the edges of the simpler imbedding. Although this new method is but the dual of the current graph construction,it has independent importance in practical applications, illustrated here by a ...

Electron transport through asymmetric ferroelectric tunnel junctions: current-voltage characteristics

, 2010
We have carried out calculations of current-voltage characteristics for the electron tunnel current through a junction with a thin insulating ferroelectric barrier assuming that interface transmissions for the left and right interfaces noticeably differ ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Inception and propagation of positive streamers in high-purity nitrogen: effects of the voltage rise-rate [PDF]

, 2012
Controlling streamer morphology is important for numerous applications. Up to now, the effect of the voltage rise rate was only studied across a wide range. Here we show that even slight variations in the voltage rise can have significant effects.

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
