Analysis of the success probability of cube attack

Tongxin xuebao, 2012
The success probability of cube attack was theoretically discussed when a boolean function was chosen at random and the algebraic degree or the number of terms in its algebraic normal form representation was restricted.The results provided theoretic ...

eCherry: A Modelica Library for Modular Dynamic Modelling of Electrochemical Reactors

Electrochemical Science Advances, EarlyView.
ABSTRACT Electrochemical reactors offer promising pathways for defossilizing the chemical industry. To understand the operation as well as to evaluate and optimise their performance and efficiency, modelling presents a crucial tool. Currently, no comprehensive open‐source library for dynamic modelling of electrochemical reactors exists, and instead ...

Differentiated policy implementation in food safety and animal welfare policymaking

European Policy Analysis, EarlyView.
Abstract Agri‐food policies are in the midst of far‐reaching transitions, including the transformation towards sustainable production and food consumption. The European Green Deal and Farm to Fork Strategy prioritize food safety and animal welfare issues, aiming to transform food systems towards more sustainability.

A Subbuteo‐Inspired Rolling Isolation System for Protecting Rigid Blocks

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study investigates a Subbuteo‐inspired rolling isolation system (RIS) as an effective means for protecting rigid blocks. The block is assumed to be rigidly connected to a curved base sector, allowing it to roll back and forth freely under dynamic excitations. The intrinsic trait of the proposed isolation concept is that the rigid block is

Multi‐Axial Subassemblage Testing System for Hybrid Simulation With Large‐Scale Structural Components

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This article presents the Multi‐Axial Subassemblage Testing facility of ETH Zurich, Switzerland (ETHZ‐MAST) for quasi‐static testing and hybrid simulation (HS) of large‐scale structural components and assemblies. The ETHZ‐MAST features a 6‐degrees‐of‐freedom (DOFs, 3 translations and 3 rotations) loading system based on a steel crosshead and ...

Energy and Exergy Efficiency Analysis of an Ejector‐Expansion Refrigeration Cycle Using the Working Fluid R134a and Its Potential Substitutes

Energy Science &Engineering, EarlyView.
ABSTRACT This paper proposes an ejector‐expansion refrigeration cycle (EERC) with two evaporating temperatures to recover partial expansion work and greatly reduces the throttling loss of the other expansion valve connected to the evaporator compared with the conventional bievaporator refrigeration cycle (CBEC).

Fully distributed consensus of nonlinear fractional multi‐agent systems based on combined event‐triggered mechanism

Mathematical Methods in the Applied Sciences, EarlyView., 2022
This article focuses on the fully distributed leader‐following consensus problem of nonlinear fractional multi‐agent systems via event‐triggered control technique. The main intention of this article is to design a novel event‐triggered mechanism, which not only takes into account both the relative error and the absolute error of the samples but also ...

Mod Tanh‐Activated Physical Neural Network MPPT Control Algorithm for Varying Irradiance Conditions

Energy Science &Engineering, EarlyView.
The proposed MPPT controller (CRT‐POA‐PID) is implemented to enhance power efficiency in the PV system. The beta‐distributed point estimation technique is used for mismatch factor correction, improving performance. Simulations show a 98.42% efficiency improvement, a 4.54 dB reduction in total harmonic distortion, and faster convergence compared to ANN ...

Analysis of Double‐Diffusive Transport and Entropy Generation in a Wavy Cylindrical Enclosure With Inner Heated Core: Effects of MHD and Radiation on Casson Cu─H2O Nanofluid

Energy Science &Engineering, EarlyView.
ABSTRACT This study investigates double‐diffusive transport and entropy generation in a wavy cylindrical enclosure containing Cu─H2O Casson nanofluid under magnetic field and thermal radiation effects. The governing equations were solved numerically using the finite element method with Galerkin formulation.

FBR for Polyolefin Production in Gas Phase: Validation of a Two‐Phase Compartmentalized Model by Comparison with CFD

Macromolecular Reaction Engineering, Volume 16, Issue 6, December 2022., 2022
Two different approaches are used to simulate the fluidization behavior of Geldart A–B particles in fluidized bed reactors operated in the bubbling regime. 2D computational fluid dynamics Euler‐Euler predictions are compared to results of a compartment‐based model with simplified fluid‐dynamics description. The compartmentalized approach is appropriate
