Proceedings of the 24th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2016
Twitter is one of the most popular social media platforms where people can share their opinions, thoughts, interests, and whereabouts. In this work, we propose a Local Event Discovery and Summarization (LEDS) framework to detect local events from Twitter. Many existing algorithms for event detection focus on larger-scale events and are not sensitive to

Experimental study of light output power for vertical GaN-based light-emitting diodes with various textured surface and thickness of GaN layer

AIP Advances, 2012
The light output power (LOP) of vertical-type GaN-based light emitting diodes (LED) with surface roughness (texture) can be changed by texture size, density, and thickness of GaN film or by the combined effects of texture formation and thickness of GaN ...

Ecological corridors in spatial planning: lessons from over 10 years of contract-based experiences in the French Alps [PDF]

Sciences, Eaux & Territoires, 2021
Ten years after the introduction of laws resulting from a national consultative process (Grenelle de l'Environnement) in which ecological connectivity was strongly promoted, what can we say about the creation of “corridors” as a new element in spatial ...

Low phase noise THz generation from a fiber-referenced Kerr microresonator soliton comb

Communications Physics, 2022
Low phase-noise THz wave generation is in high demand for applications such as wireless communications and radars. Here, the authors generate low-noise THz waves via photodetection of the carrier of a Kerr frequency comb, which is repetition-rate ...
