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

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

Kinematic Hopf algebra for amplitudes from higher-derivative operators

Journal of High Energy Physics
Recently it has been shown that Bern-Carrasco-Johansson (BCJ) numerators of colour-kinematic duality for tree-level scattering amplitudes in Yang-Mills theory (coupled with scalars) can be determined using a quasi-shuffle Hopf algebra.

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).

Two‐phase model for the excavation analysis in partially saturated soft soils using the particle finite element method

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 2, Page 145-186, 10 February 2023., 2023
Abstract A two‐phase velocity‐pressure stabilized formulation is proposed for the numerical analysis of mechanized excavations in partially saturated soft soils using the Particle Finite Element Method (PFEM). The fully coupled formulation is based on the theory of porous media in association with the Soil Water Characteristic Curve and the porosity ...

SYNTHESIS METHODS OF ALGEBRAIC NORMAL FORM OF MANY-VALUED LOGIC FUNCTIONS

Системный анализ и прикладная информатика, 2016
The rapid development of methods of error-correcting coding, cryptography, and signal synthesis theory based on the principles of many-valued logic determines the need for a more detailed study of the forms of representation of functions of many-valued ...
