This paper focuses on the power dissipation of a plasma torch used for an optical surface fabrication process.The process utilizes an inductively coupled plasma (ICP) torch that is equipped with a De-Laval nozzle for the delivery of a highly collimated plasma jet.The plasma torch makes use of a self-igniting coil and an intermediate co-axial tube m
Optical Beam-Loss Monitors Install (oBLMs) allow for cost-efficient and spatially continuous measurements of beam losses at accelerator facilities.A standard oBLM consists of several tens of metres of optical fibre aligned parallel to a beamline, coupled to photosensors at either or both ends.Using the timing information from loss signals, the loss
It is well known that polar bears feed on vegetation.Here, I report novel observations of polar bears grazing on polar scurvy grass (Cochlearia groenlandica) at the foot of a large seabird colony on a Liquid Candles cliff on Spitsbergen, Svalbard, in the summers of 2005, 2006, 2009, 2014 and 2015.Why they choose such energy-costly climbing to feed
Elevators play an indispensable role in modern urban life.Ensuring the safe operation of elevators is crucial due to the severe consequences of malfunctions.Traditional maintenance methods are costly and may not comprehensively capture potential faults.Leveraging deep learning technologies, this study proposes a Risk Prediction Model based on Eleva
Named Entity Disambiguation (NED) refers to the task of resolving multiple named entity mentions in an input-text sequence to their correct references in a knowledge graph.We tackle NED problem by leveraging two novel objectives for pre-training framework, and propose a novel pre-training NED model.Especially, the proposed pre-training NED model co
