Allometric Biomass Models for European Beech and Silver Fir: Testing Approaches to Minimize the Demand for Site-Specific Biomass Observations
biomass Romania site-specific Fagus sylvatica Abies alba Bayesian model mixed effect models
2023/12/11
In this paper, site-specific allometric biomass models were developed for European beech (Fagus sylvatica L.) and silver fir (Abies alba Mill.) to estimate the aboveground biomass in inca virgin?fores...
Exploring combinations of multi-temporal and multi-frequency radar backscatter observations to estimate above-ground biomass of tropical forest
Above-ground biomass Tropical forest Synthetic Aperture Radar Multi-frequency Multi-temporal
2024/2/5
Approaches exploiting the complementary information on forest above-ground biomass (AGB) contained in multi-temporal and multi-frequency radar backscatter have hardly been explored in the tropics. Hav...
Recently Bar-On et al. proposed the DLCT for a tighter analysis of probabilities for differential-linear distinguishers. We extend the analysis of the DLCT, and gain new insights about this notion.
SIMON and SPECK families of block ciphers are well-known lightweight ciphers designed by NSA. In this note, based on the previous investigations on SIMON, a closed formula for the squared correlations...
SYNOPTIC OBSERVATIONS OF CALVING EVENTS IN ANTARCTICA USING SPACEBORNE IMAGES
Antarctica Calving Optical Images Rifts Icebergs
2019/2/28
Iceberg calving is the detachment of ice from ice shelves or glaciers. Although calving is a natural phenomenon, an abnormal rate of calving can be a threat to ice shelves. Some of the events were so ...
Observations on the Dynamic Cube Attack of 855-Round TRIVIUM from Crypto'18
Dynamic Cube attack Division Property MILP
2018/11/6
Recently, another kind of dynamic cube attack is proposed by Fu et al. With some key guesses and a transformation in the output bit, they claim that, when the key guesses are correct, the degree of th...
MAPPING GLOBAL OCEAN SURFACE ALBEDO FROM SATELLITE OBSERVATIONS: MODELS, ALGORITHMS, AND DATASETS
Albedo Ocean BRDF Remote sensing Radiative transfer Surface radiation budget
2018/5/14
Ocean surface albedo (OSA) is one of the important parameters in surface radiation budget (SRB). It is usually considered as a controlling factor of the heat exchange among the atmosphere and ocean. T...
REMOTE SENSING OBSERVATIONS AND NUMERICAL SIMULATION FOR MARTIAN LAYERED EJECTA CRATERS
Martian Surface Impact Crater Remote Sensing Morphological Characteristic Numerical Simulation
2018/5/14
To understand past Martian climates, it is important to know the distribution and nature of water ice on Mars. Impact craters are widely used ubiquitous indicators for the presence of subsurface water...
SURFACE SNOW DENSITY OF EAST ANTARCTICA DERIVED FROM IN-SITU OBSERVATIONS
Surface snow density Matrix completion Empirical Orthogonal Function Kriging
2018/5/15
Models based on physical principles or semi-empirical parameterizations have used to compute the firn density, which is essential for the study of surface processes in the Antarctic ice sheet. However...
POSSIBILITY OF CLOUDLESS OPTICAL REMOTE SENSING IMAGES ACQUISITION STUDY BY USING METEOROLOGICAL SATELLITE OBSERVATIONS
Cloud total amount Cloudless image acquisition Fengyun(FY) satellite Ziyuan-3 (ZY-3) satellite
2018/5/16
Optical remote sensing images have been widely used in feature interpretation and geo-information extraction. All the fundamental applications of optical remote sensing, are greatly influenced by clou...

Data assimilation WRF/Chem Aerosol Aircraft
2018/5/16
A three-dimensional variational data assimilation system is implemented within the Weather Research and Forecasting/Chemistry model, and the control variables consist of eight species of the Model for...
IMPROVING UNDERWATER ACCURACY BY EMPIRICAL WEIGHTING OF IMAGE OBSERVATIONS
underwater photogrammetry, image quality, bundle adjustment, image observation weighting
2018/6/4
An underwater imaging system with camera and lens behind a flat port does not behave as a standard pinhole camera with additional parameters. Indeed, whenever the entrance pupil of the lens is not in ...

2017/7/13
Shabkola is a village located in Mazandaran province of northern Iran that suffers from the mass movement happening in the upstream. Deforestation and changes to land use are the main reasons for the ...
New Observations on Invariant Subspace Attack
Invariant subspace attack AES-like Lightweight block ciphers
2017/3/28
Invariant subspace attack is a novel cryptanalytic technique which breaks several recently proposed lightweight block ciphers. In this paper, we propose a new method to bound the dimension of some inv...
