Food Systems Transformation Kenya Policy Options Lessons
2024/4/1
The International Food Policy Research Institute (IFPRI), a CGIAR Research Center established in 1975, provides research-based policy solutions to sustainably reduce poverty and end hunger and ma...
Improvements of Thermal and Thermochemical Properties of Rosin by Chemical Transformation for Its Use as Biofuel
Rosin Isomerization Reduction Esterification Properties estimation
2024/2/29
The use of raw materials from renewable sources has become an important topic for different industries. Pine oleoresin is one of the most important renewable sources. It is composed of a broad range o...
On Noncommutative Cryptography and homomorphism of stable cubical multivariate transformation groups of infinite dimensional affine spaces
Multivariate Cryptography stable transformation groups and semigroups decomposition problem of nonlinear multivariate map into given generators
2019/6/3
Noncommutative cryptography is based on applications of algebraic structures like noncommutative groups, semigroups and non-commutative rings. Its inter-section with Multivariate cryptography contains...
CPA-to-CCA Transformation for KDM Security
public-key encryption key-dependent message security chosen ciphertext security
2019/6/3
We show that chosen plaintext attacks (CPA) security is equivalent to chosen ciphertext attacks (CCA) security for key-dependent message (KDM) security. Concretely, we show how to construct a public-k...
Security of the Fiat-Shamir Transformation in the Quantum Random-Oracle Model
Fiat-Shamir post-quantum digital signatures
2019/3/1
The famous Fiat-Shamir transformation turns any public-coin three-round interactive proof, i.e., any so-called sigma-protocol, into a non-interactive proof in the random-oracle model. We study this tr...
SUPERPIXEL BASED FACTOR ANALYSIS AND TARGET TRANSFORMATION METHOD FOR MARTIAN MINERALS DETECTION
Superpixel Factor Analysis Target Transformation Minerals detection Mars
2018/5/15
The Factor analysis and target transformation (FATT) is an effective method to test for the presence of particular mineral on Martian surface. It has been used both in thermal infrared (Thermal Emissi...
RESEARCH ON COORDINATE TRANSFORMATION METHOD OF GB-SAR IMAGE SUPPORTED BY 3D LASER SCANNING TECHNOLOGY
GB-SAR Interference measurement 3D laser scanning Coordinate Transformation
2018/5/15
In the image plane of GB-SAR, identification of deformation distribution is usually carried out by artificial interpretation. This method requires analysts to have adequate experience of radar imaging...

Aircraft Target Detection Radial Gradient Transformation Rotation-Invariant Feature Polar Form Look-up Table
2018/5/17
Aiming at the problem that the target may have different orientation in the unmanned aerial vehicle (UAV) image, the target detection algorithm based on the rotation invariant feature is studied，and t...
TARGET TRANSFORMATION CONSTRAINED SPARSE UNMIXING (TTCSU) ALGORITHM FOR RETRIEVING HYDROUS MINERALS ON MARS: APPLICATION TO SOUTHWEST MELAS CHASMA
Prior information Sparse unmixing Hydrous minerals Mars CRISM
2018/5/15
Quantitative analysis of hydrated minerals from hyperspectral remote sensing data is fundamental for understanding Martian geologic process. Because of the difficulties for selecting endmembers from h...
An Efficiency-Preserving Transformation from Honest-Verifier Statistical Zero-Knowledge to Statistical Zero-Knowledge
statistical zero-knowledge honest-verifier statistical zero-knowledge instance-dependent commitment schemes
2018/3/6
We present an unconditional transformation from any honest-verifier statistical zero-knowledge (HVSZK) protocol to standard SZK that preserves round complexity and efficiency of both the verifier and ...
A Modular Analysis of the Fujisaki-Okamoto Transformation
public-key encryption Fujisaki-Okamoto transformation tight reductions
2017/6/26
The Fujisaki-Okamoto (FO) transformation (CRYPTO 1999 and Journal of Cryptology 2013) turns any weakly secure public-key encryption scheme into a strongly (i.e., IND-CCA) secure one in the random orac...
