Based on Investigation and Assessment on Rational Exploitation and Utilization of Groundwater Resources in Typical Areas of the Hexi Corridor, the thesis studies on groundwater and environmental probl...
AN ATTEMPT TO DEVELOP AN ENVIRONMENTAL INFORMATION SYSTEM OF ECOLOGICAL INFRASTRUCTURE FOR EVALUATING FUNCTIONS OF ECOSYSTEM-BASED SOLUTIONS FOR DISASTER RISK REDUCTION (ECO-DRR)
Ecological infrastructure Eco-DRR Environmental Information System Ecological disaster reduction Web-GIS
2016/11/30
“Ecological Infrastructure (EI)” are defined as naturally functioning ecosystems that deliver valuable services to people, such as healthy mountain catchments, rivers, wetlands, coastal dunes, and nod...
Pseudorandom Generators from Regular One-way Functions: New Constructions with Improved Parameters
Foundations Pseudorandom Generators One-way Functions Randomized Iterate
2016/1/23
We revisit the problem of basing pseudorandom generators on regular one-way functions, and present the following constructions.
SUSTAINABLE LAND-USE PLANNING SUPPORT BY GIS-BASED EVALUATION OF LANDSCAPE FUNCTIONS AND POTENTIALS
Geographical Information Science landuse spatial analysis sustainable development landscape functions and potentials land-use planning
2016/1/3
The paper presents an example of the application of the landscape functions and natural potentials methodology to the environmental assessment in the upland area of Pradnik and Dlubnia rivers catchmen...
Analysis of Score Functions for the Automatic Registration of Terrestrial Laser Scans
Terrestrial Laser Scanning Registration Range Images
2015/12/16
Terrestrial laser scanners are more and more popular, e.g. for surveying purposes, cultural heritage, city modelling or architectural
applications. Usually different points of view are necessary to a...
Speckle Denoising Based on Bivariate Shrinkage Functions and Dual-Tree Complex Wavelet Transform
Transformation Algorithms SAR Radiometric Processing, Image
2015/11/20
Bivariate shrinkage functions (bsf) statistically denoted as joint probability density functions (pdf) and noise pdf, can be united by MAP to denoise image. Because the intensity of speckle in synthet...
ESTIMATION OF THE SPECTRAL SENSITIVITY FUNCTIONS OF UN-MODIFIED AND MODIFIED COMMERCIAL OFF-THE-SHELF DIGITAL CAMERAS TO ENABLE THEIR USE AS A MULTISPECTRAL IMAGING SYSTEM FOR UAVS
UAV Remote Sensing Multispectral COTS Spectral Sensitivity Open Source CHDK
2015/9/10
Commercial off-the-shelf (COTS) digital cameras on-board unmanned aerial vehicles (UAVs) have the potential to be used as multispectral imaging systems; however, their spectral sensitivity is usually ...
On the impossibility of efficiently combining collision resistant hash functions
resistant hash functions efficiently combining
2015/8/5
Let H1, H2 be two hash functions. We wish to construct a new hash function H that is collision resistant if at least one of H1 or H2 is collision resistant. Concatenating the output of H1 and H2 clear...
Homomorphic Signatures for Polynomial Functions
Polynomial Functions Homomorphic Signatures
2015/8/5
We construct the first homomorphic signature scheme that is capable of evaluating multivariate polynomials on signed data. Given the public key and a signed data set, there is an efficient algorithm t...
Algebraic pseudorandom functions with improved efficiency from the augmented cascade
improved efficiency pseudorandom functions
2015/8/5
We construct an algebraic pseudorandom function (PRF) that is more efficient than the classic Naor-Reingold algebraic PRF. Our PRF is the result of adapting the cascade construction, which is the basi...
Constrained Pseudorandom Functions and Their Applications
Their Applications Pseudorandom Functions
2015/8/5
We put forward a new notion of pseudorandom functions (PRFs) we call Constrained PRFs. In a standard PRF there is a master key k that enables one to evaluate the function at all points in the domain o...
