RADIATIVE TRANSFER MODEL SIMULATIONS TO DETERMINE THE NIGHT TIME FOG DETECTION THRESHOLD
Fog detection, Radiative Transfer Model SBDART Indo-Gangetic plain Brightness temperature difference threshold Middle Infrared Thermal Infrared
2019/2/28
Every winter the Indo-Gangetic plains (IGP) of northern India are severely impacted both socially and economically by fog. For night time fog detection, visible imagery cannot be used. Also, as emissi...
A SWEEP-PLANE ALGORITHM FOR THE SIMPLIFICATION OF 3D BUILDING MODELS IN THE APPLICATION SCENARIO OF WIND SIMULATIONS
3D City models Automated Processing BRep
2018/11/9
As the number of virtual 3D city models is steadily increasing, so are the possible applications that take advantage of them. 3D models can be used for applications that range from simple graphic visu...

Simulations of Optical Emissions for Attacking AES and Masked AES
Photonic side channel Side channel analysis Light emission
2018/3/29
In this paper we present a novel attack based on photonic emission analysis targeting software implementations of AES. We focus on the particular case in which the attacker can collect the photonic em...
A meteoroid penetrating the Earth’s atmosphere leaves behind a trail
of dense plasma embedded in the lower E/upper D-region ionosphere. While
radar measurements of meteor trail evolution have been c...
Ion thermal effects on E-region instabilities: 2D kinetic simulations
E-region electrojet Ionospheric irregularities Plasma instabilities
2017/3/22
Radars frequently receive strong returns from naturally occurring plasma density irregularities centered around
100 km altitude in the atmosphere. These E-region ionospheric irregularities occur when...
INFLUENCE OF RIVER BED ELEVATION SURVEY CONFIGURATIONS AND INTERPOLATION METHODS ON THE ACCURACY OF LIDAR DTM-BASED RIVER FLOW SIMULATIONS
LiDAR Digital Terrain Model River Bed Survey Configuration Interpolation Integration Flow Simulation
2016/10/14
In this paper, we investigated how survey configuration and the type of interpolation method can affect the accuracy of river flow simulations that utilize LIDAR DTM integrated with interpolated river...
Why Monte Carlo Simulations are Inferences and not Experiments
Monte Carlo method computer simulations inference experiment randomness
2016/5/27
Monte Carlo Simulations arrive at their results by introducing randomness, sometimes derived from a physical randomizing device. Nonetheless, we argue, they open no new epistemic channels beyond that ...

Numerical simulations of collisional disruption of rotating gravitational aggregates:Dependence on material properties
Asteroids Planetesimals Dynamics N-body simulations Collisional physics
2015/12/25
Our knowledge of the strengths of small bodies in the Solar System is limited by our poor understanding of their internal structures, and this, in turn, clouds our understanding of the formation and e...
