Modelling and Comparing Shading Effects of 3D Tree Structures with Virtual Leaves
shadow model TLS LiDAR agroforestry QSM Prunus avium insolation shade cast
2023/12/6
Reduced solar radiation brought about by trees on agricultural land can both positively and negatively affect crop growth. For a better understanding of this issue, we aim for an improved simulation o...
Layer-by-layer assembly of nanomultilayer structures: Reinforcement of expanded char reduced the toxicity and fire hazard of epoxy resins
Epoxy resin Fire safety Intumescent flame retardant Smoke suppression Flame retardancy
2023/11/16
Epoxy resins (EP) have been widely applied in chemical engineering, composite materials, and aerospace. Nevertheless, the high fire hazard of flammable epoxy resins, which release considerable hazardo...
Cryptanalysis of Round-Reduced KECCAK using Non-Linear Structures
KECCAK SHA-3 Hash function
2019/8/2
In this paper, we present new preimage attacks on KECCAK-384 and KECCAK-512 for 2, 3 and 4 rounds. The attacks are based on non-linear structures (structures that contain quadratic terms). These struc...
Effects of inhibiting starch branching enzymes on molecular and crystalline structures of starches from endosperm different regions in rice
Crystalline structure Endosperm regional tissue Molecular structure Rice Starch Starch branching enzyme
2023/8/9
Mature endosperm was separated regionally into different parts in three rice cultivars, Te-qing (TQ), Wu-xiang 9915 (WX9915) and Guang-ling-xiang-nuo (GLXN), and their transgenic lines with inhibition...
Continuously Non-Malleable Secret Sharing for General Access Structures
Secret sharing Non-malleability Leakage resilience
2019/6/3
We study leakage-resilient continuously non-malleable secret sharing, as recently intro- duced by Faonio and Venturi (CRYPTO 2019). In this setting, an attacker can continuously tamper and leak from a...
We study approaches to generalized Feistel constructions with low-degree round functions with a focus on x → x^3. Besides known constructions, we also provide a new balanced Feistel construction...
Uncovering Algebraic Structures in the MPC Landscape
MPC Landscape Commuting Permutations Systems
2019/3/13
A fundamental problem in the theory of secure multi-party computation (MPC) is to characterize functions with more than 2 parties which admit MPC protocols with information-theoretic security against ...
Secret-Sharing Schemes for General and Uniform Access Structures
secret sharing conditional disclosure of secrets protocols private simultaneous messages protocols
2019/3/4
A secret-sharing scheme allows some authorized sets of parties to reconstruct a secret; the collection of authorized sets is called the access structure. For over 30 years, it was known that any (mono...
PARAMETRICAL ANALYSIS AND DIGITAL FABRICATION OF THIN SHELL STRUCTURES: THE IMPACT OF CONSTRUCTION TECHNIQUE ON THE RESULTING GEOMETRY OF THE GAUSSIAN VAULTS OF ELADIO DIESTE
Gaussian Vaults Eladio Dieste Geometry
2019/3/2
The objective of this article is to analyze the state-of-art regarding the construction process of the Gaussian Vaults of the Uruguayan civil engineer Eladio Dieste and to identify the elements that u...
Stronger Leakage-Resilient and Non-Malleable Secret-Sharing Schemes for General Access Structures
Non-malleable secret sharing Leakage-resilient secret sharing Non-malleable extractors
2018/12/3
In this work we present a collection of compilers that take secret sharing schemes for an arbitrary access structures as input and produce either leakage-resilient or non-malleable secret sharing sche...
IDENTIFICATION OF POTENTIAL SITES FOR WATER HARVESTING STRUCTURES USING GEOSPATIAL TECHNIQUES AND MULTI-CRITERIA DECISION ANALYSIS
Water harvesting structures Remote sensing and GIS Watershed management MSE AHP
2019/2/27
Changing hydrological phenomenon and increase the water demand in all sectors create a huge problem of water scarcity. Precipitation is one and only major source to mitigate this problem. In Central I...
Construction of Lightweight MDS Matrices from Generalized Feistel Structures
Lightweight cryptography MDS matrix Generalized Feistel Structures
2018/11/12
This paper investigates the construction of lightweight MDS matrices with generalized Feistel structures (GFS). The approach developed by this paper consists in deriving MDS matrices from the product ...
Asymptotically Ideal CRT-based Secret Sharing Schemes for Multilevel and Compartmented Access Structures
cryptographic protocols secret sharing
2018/11/8
Multilevel and compartmented access structures are two important classes of access structures where participants are grouped into levels/compartments with different degrees of trust and privileges. Th...
Non-Malleable Secret Sharing for General Access Structures
Non-Malleable Codes Secret Sharing
2018/8/20
Goyal and Kumar (STOC'18) recently introduced the notion of non-malleable secret sharing. Very roughly, the guarantee they seek is the following: the adversary may potentially tamper with all of the s...

MILP Generalized Feistel structure Switching mechanism
2018/8/16
Some features of Feistel structures have caused them to be considered as an efficient structure for design of block ciphers. Although several structures are proposed relied on Feistel structure, the t...
