COPERNICUS BIG DATA AND GOOGLE EARTH ENGINE FOR GLACIER SURFACE VELOCITY FIELD MONITORING: FEASIBILITY DEMONSTRATION ON SAN RAFAEL AND SAN QUINTIN GLACIERS
Big Data Google Earth Engine Sentinel-1 Glacier velocity field SAR off-set tracking San Rafael Glacier San Quintin Glacier
2018/5/11
The glaciers are a natural global resource and one of the principal climate change indicator at global and local scale, being influenced by temperature and snow precipitation changes. Among the parame...
The router is a key element for a network. We describe a scheme to realize genuine quantum routing of single-photon pulses based on cascading of conditional quantum gates in a Mach-Zehnder interferome...
A Tabletop Demonstration of Atmospheric Dynamics:Baroclinic Instability
Tabletop Demonstration Atmospheric Dynamics Baroclinic Instability
2015/7/22
Here we study a fundamental instability mechanism of the atmosphere that affects us very directly in terms of mid-latitude winter weather. We provide a hands-on demonstration of this instability using...
A Laboratory Demonstration of Coriolis Effects on Wind-Driven Ocean Currents
Wind-Driven Ocean Currents Coriolis Effects
2015/7/20
Here we study the mechanism by which the wind drives ocean circulation. We induce cyclonic and anticyclonic circulation by blowing air over the surface of a rotating tank of water using fans co-rotati...
Lake in a Bottle:A Laboratory Demonstration of the Unusual Stability Properties of Freshwater
Lake in a Bottle Unusual Stability Properties Freshwater
2015/7/13
Using simple laboratory gear, students can simulate the stratification properties of a freshwater lake and the impact of salt on the relationship between temperature and density. Because some students...
Demonstration of Strong Near-Field Radiative Heat Transfer between Integrated Nanostructures
Thermal transport thermal radiation near-fi eld radiation microelectromechanical systems (MEMS) surface phonon-polariton
2015/8/6
Near-field heat transfer recently attracted growing interest but was demonstrated experimentally only in macroscopic systems. However, several projected applications would be relevant mostly in ...
Experimental demonstration of a broadband array of invisibility cloaks in the visible frequency range
Experimental demonstration broadband array invisibility cloaks visible frequency range Optics
2012/4/20
Very recently Farhat et al. [1] have suggested that arrays of invisibility cloaks may find important applications in low-interference communication, noninvasive probing, sensing and communication netw...
Measurement requirements for a near-Earth asteroid impact mitigation demonstration mission
Near-Earth Asteroids Impact Mitigation Spacecraft Missions
2011/8/17
Abstract: A concept for an Impact Mitigation Preparation Mission, called Don Quijote, is to send two spacecraft to a Near-Earth Asteroid (NEA): an Orbiter and an Impactor. The Impactor collides with t...

A concept for an Impact Mitigation Preparation Mission, called Don Quijote, is to send two spacecraft to a Near-Earth Asteroid (NEA): an Orbiter and an Impactor. The Impactor collides with the asteroi...
Demonstration of temporal cloaking
Demonstration temporal cloaking manipulate control electromagnetic fields
2011/8/4
Abstract: Recent research has uncovered a remarkable ability to manipulate and control electromagnetic fields to produce effects such as perfect imaging and spatial cloaking. To achieve spatial cloaki...
Regression, model misspecification and causation, with pedagogical demonstration
Regression variable omission model incomplete bias
2010/9/20
This paper shows, by a proposition and a numerical example, how a classic simple or multiple normal regression can achieve with 0.99 probability a near perfect fit to a random sample of any size but d...
Demonstration of high-Q TE-TM photonic crystal nanobeam cavities
high-Q TE-TM photonic crystal nanobeam cavities Physics
2010/11/16
We experimentally demonstrate high Quality factor dual-polarized TE-TM photonic crystal nanobeam cavities. The free-standing nanobeams are fabricated in a 500 nm thick silicon layer, and are probed u...
