Beijing Lightning Network (BLNET) and the Observation on Preliminary Breakdown Processes
Atmospheric Research, 2016Abstract Beijing Lightning Network (BLNET), a regional multi-frequency-band lightning detection and location network, has been developed for both research and operational purposes. The network consisted of 15 stations in 2014, covering an area of about 100 km × 85 km in Beijing area.

Preliminary Breakdown Pulses (PBP): A Review on Available Data and Models
Electric Power Systems ResearchLightning is a major risk for humans, animals, and electrical systems. Many researches focused on the fully developed events, such as the Return Stroke (RS) current, the emitted electromagnetic fields, and the phenomenon modeling. However, there is poor understanding regarding precursors, such as Preliminary Breakdown Pulses (PBP).

Preliminary experimental results on water breakdown in tens nanoseconds region
2011 IEEE International Conference on Dielectric Liquids, 2011Deionized water is a good dielectric material. In this paper, preliminary investigations are carried out on water breakdown in tens nanoseconds region via a switch with “point-plane” electrodes. The switch is set up on the output port of a wave erection Marx generator, which can deliver a minus high voltage pulse with an amplitude of 0∼300 kV, and a ...

Preliminary evaluation of laser-induced breakdown spectroscopy for tissue classification
Spectrochimica Acta Part B: Atomic Spectroscopy, 2009Laser-induced breakdown spectroscopy (LIBS) is an on-line, real-time technology that can produce immediate information about the elemental contents of tissue samples. We have previously shown that LIBS may be used to distinguish cancerous from non-cancerous tissue.

Preliminary estimate of the cost breakdown for the Fusion Ignition Experiment IGNITEX
IEEE Thirteenth Symposium on Fusion Engineering, 2003A preliminary estimate of the cost breakdown for the Fusion Ignition Experiment (IGNITEX) is presented. The IGNITEX concept proposed by M.N. Rosenbluth, W.F. Weldon, and H.H. Woodson (1987) is based on B. Coppi's idea for a compact thermonuclear experiment and has the potential to produce and control ignited plasmas at a relatively low cost ($130M ...

Characteristic of preliminary breakdown preceding negative return stroke in Malaysia
2015 IEEE Conference on Energy Conversion (CENCON), 2015This paper describes a study on the characteristics of preliminary breakdown pulses (PBPs) preceding negative return strokes. Such characterization is needed due to the lack of available data, especially for negative lightning, in Malaysia. Measurements were carried out in Johor Bahru, Malaysia in October 2014 using broadband antennas and a high ...

Comparison of preliminary breakdown pulses observed in Sweden and in Sri Lanka
Journal of Atmospheric and Solar-Terrestrial Physics, 1998Abstract In this paper we have analysed breakdown pulse trains preceding the first return stroke in 47 negative cloud-to-ground (CG) lightning flashes observed in Sri Lanka (tropics) and that in 41 negative CG flashes recorded in Sweden (temperate regions). In the data obtained in Sri Lanka, breakdown pulses could be detected only in nine flashes. In

Characteristic Pulse Trains of Preliminary Breakdown in Four Isolated Small Thunderstorms
Journal of Geophysical Research D: Atmospheres, 2017AbstractUsing a low‐frequency six‐station local network, preliminary breakdown (PB) pulses not followed or followed by negative return stroke (RS), which are defined as PB‐type and PB cloud‐to‐ground (PBCG)‐type flashes, are analyzed based on four isolated small thunderstorms for the first time.

Communication robots are expected to help elderly people that live alone. However, it is difficult for existing conversation systems to communicate smoothly. One reason for this is that the robot cannot recognize conversation breakdowns. To solve this problem, we tried to detect human motion characteristics when conversation is not established.

Bipolar Disorders, 2013
ObjectivesIndividuals with bipolar disorder (BD) are disproportionately affected by symptoms of being overweight and metabolic syndrome when compared to the general population. The pertinence of this observation is underscored by observations that excess weight is associated with a more complex illness presentation, course, and outcome in BD.
