用于锦屏深地核天体物理研究的强流加速装置的设计与试验进展
深地实验室 强流加速装置 直接测量
2021/2/23
对揭示元素形成及天体起源具有重要作用的关键低能核反应由于反应截面较小，同时受宇生高能射线影响，在地面环境难以进行直接测量。在极低本底的深地环境中，利用强流离子加速器打靶，进一步提高关心核反应的发生率，就可在地球开展接近伽莫夫能区低能核反应截面直接测量。锦屏深地实验室（CJPL）具有优越的地理环境，可有效屏蔽宇生高能射线。依托CJPL的有利条件，中国原子能科学研究院正在开展核天体物理关注能区核反应直...
SYNTHETIC APERTURE RADAR (SAR) BASED CLASSIFIERS FOR LAND APPLICATIONS IN GERMANY
LBM-DE Land cover polarimetry SAR Sentinel-1 Sentinel-2
2016/7/5
Land cover information is essential for urban planning and for land cover change monitoring. This paper presents an overview of the work conducted at the Federal Agency for Cartography and Geodesy (BK...
Case Study–Use of Video Clips in a Virtual Learning Environment to enhance the learning experience of our students
Video clips student centred learning multi layered teaching enhanced student experience student opinions
2016/1/29
This paper considers how the use of video clips integrated into a virtual learning environment has been perceived by students on a land surveying module within a civil engineering degree. The increasi...
MAPPING THE WORLD - A NEW APPROACH FOR VOLUNTEERED GEOGRAPHIC INFORMATION IN THE CLOUD
OSM Volunteered Geographic Information
2015/6/17
The OSM project provides a geodata basis for the entire world under the CC-SA licence agreement. But some parts of the world are
mapped more densely compared to other regions. However, many less dev...
EVALUATING STATISTICAL SHAPE MODELS FOR AUTOMATIC LANDMARK GENERATION ON A CLASS OF HUMAN HANDS
Statistics Automation Classification
2015/6/2
In this article, we present an evaluation of the application of statistical shape models for automatic landmark generation from a
training set of deformable shapes and in particular, from a class of...
AUTOMATIC BUILDING RECONSTRUCTION FROM AERIAL IMAGES: A GENERIC BAYESIAN FRAMEWORK
Building Reconstruction Modeling
2015/6/1
A novel system for automatic building reconstruction from multiple aerial images is presented. Compared to previous works, this
approach uses a very generic modeling of buildings as polyhedral shapes...
BIO-OPTICAL DATA INTEGRATION BASED ON A 4D DATABASE SYSTEM APPROACH
Bio-optical Properties Multi Source Data
2015/5/6
Bio-optical characterization of water bodies requires spatio-temporal data about Inherent Optical Properties and Apparent Optical Properties which allow the comprehension of underwater light field ai...
EROSION MODELLING IN A MEDITERRANEAN SUBCATCHMENT UNDER CLIMATE CHANGE SCENARIOS USING PAN-EUROPEAN SOIL EROSION RISK ASSESSMENT (PESERA)
Erosion, Runoff PESERA Climate change
2015/5/6
The Mediterranean region is particularly prone to erosion. This is because it is subject to long dry periods followed by heavy bursts of erosive rainfall, falling on steep slopes with fragile soils,...
LAND-USE AND LAND-COVER DYNAMICS MONITORED BY NDVI MULTITEMPORAL ANALYSIS IN A SELECTED SOUTHERN AMAZONIAN AREA (BRAZIL) FOR THE LAST THREE DECADES
NDVI multitemporal dynamics Landsat series
2015/5/6
This study aims to analyse the dynamics of land-use and land-cover (LULC) in a selected southern Amazonian area (Brazil), monitoring and distinguishing trajectories in NDVI (Normalized Difference Ve...
CATCHMENT PROPERTIES IN THE KRUGER NATIONAL PARK DERIVED FROM THE NEW TANDEM-X INTERMEDIATE DIGITAL ELEVATION MODEL (IDEM)
TanDEM-X ASTER GDEM2 SRTM
2015/5/6
Digital Elevation Models (DEM) represent fundamental data for a wide range of Earth surface process studies. Over the past years the German TanDEM-X mission acquired data for a new, truly global Dig...

FEATURE EXTRACTION FOR QUALITY ASSESSMENT OF AERIAL IMAGE SEGMENTATION
Protocol, Performance, Segmentation
2015/3/24
We present a new evaluation methodology and a feature extraction scheme for segmentation algorithms in the context
of photo-interpretation. The novelty of the proposed methodology is that subjective ...
In this contribution we intend to present a complete system that takes a video sequence of a static scene as input and
generates visual 3D model. The system can deal with images acquired by an uncali...
