Academy of Mathematics and Systems Science, CAS Colloquia & Seminars： On the dimension of limit sets on the real projective plane via stationary measures
实射影平面 极限集 维数 平稳测度
2023/11/29
I will present a dimension jump result of limit sets on RP^2 for representations of surface groups in SL(3,R). For Anosov representations, we prove the equality between the Hausdorff dimension and the...

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...
INFRARED ROTATION PLANE RADAR CHANGE DETECTION
Infrared Rotation Plane Radar Change Detection Depth Information Mixed Gaussian Background Modeling
2018/5/15
The existing change detection method mainly stays on the pixel-level, which is very susceptible to light, shadow, etc. And the complex calculation and analysis for each pixel reduce the detection effi...
PLANE-BASED REGISTRATION OF SEVERAL THOUSAND LASER SCANS ON STANDARD HARDWARE
Terrestrial laser scanning registration plane-to-plane correspondences stochastic modelling large networks
2018/6/5
The automatic registration of terrestrial laser scans appears to be a solved problem in science as well as in practice. However, this assumption is questionable especially in the context of large proj...

Multi-spectral camera system monitoring the atmosphere the focal plane subsystem the near infrared spectrum
2017/7/13
The Sentinel-4 payload is a multi-spectral camera system which is designed to monitor atmospheric conditions over Europe. The German Aerospace Center (DLR) in Berlin, Germany conducted the verificatio...
It’s a Bird,It’s a Plane,It’s–a Key Discovery About Human Memory
Bird Plane Key Human Memory
2017/3/14
As Superman flies over the city, people on the ground famously suppose they see a bird, then a plane, and then finally realize it’s a superhero. But they haven’t just spotted the Man of Steel – they’v...

Plane carrying Buzz Aldrin lands New Zealand
2016/12/13
The plane carrying Buzz Aldrin out of Antarctica has reached Christchurch, New Zealand.A Safair cargo aircraft touched down at Christchurch International Airport at approximately 4:25 a.m. (local time...
Astronomers have obtained observations of the smallest asteroid ever characterized in detail. At 2 meters (6 feet) in diameter, the tiny space rock is small enough to be straddled by a person in a hyp...
ESTIMATION OF AERODYNAMIC ROUGHNESS AND ZERO PLANE DISPLACEMENT USING MEDIUM DENSITY OF AIRBORNE LIDAR DATA
Airborne LiDAR Aerodynamic Roughness Length Zero Plane Displacement Forest
2016/10/14
This paper presents a framework to estimate aerodynamic roughness over specific height (zo/H) and zero plane displacement (d/H) over various landscapes in Kelantan State using airborne LiDAR data. The...

KNEE ABDUCTION MOMENT KNEE ADDUCTION MOMENT KNEE FLEXION MOMENT
2017/4/13
Although effects of workload and cadence on sagittal plane knee biomechanics in cycling have been widely studied, few studies have examined their impact on the frontal plane.
Purpose: The purpose of ...
With the rapid improvement of LIDAR systems regarding point density and accuracy in relation to the (application dependent)
requirements, robustness, efficiency and automation of the modeling process...
