A Constructal-Theory-Based Methodology to Determine the Configuration of Empty Channels Used in the Resin Impregnation of a Square Porous Plate

open access: yesFluids, 2023
Liquid composite molding techniques are largely used to produce pieces such as truck cabins or wind turbine blades. The liquid resin infusion processes use a network of injection channels to improve the resin flow through a porous-reinforced medium.

Constructive matrix theory [PDF]

open access: yesJournal of High Energy Physics, 2007
We extend the technique of constructive expansions to compute the connected functions of matrix models in a uniform way as the size of the matrix increases. This provides the main missing ingredient for a non-perturbative construction of the $ϕ^{\star 4}_4$ field theory on the Moyal four dimensional space.

Constructively Formalizing Automata Theory [PDF]

open access: yes, 2000
We present a constructive formalization of the Myhill-Nerode theorem on the minimization of nite automata that follows the account in Hopcroft and Ullman's book Formal Languages and Their Relation to Automata. We chose to formalize this theorem because it illustrates many points critical to formalization of computational mathematics, especially the ...

Constructal theory of pattern formation [PDF]

open access: yesHydrology and Earth System Sciences, 2007
This review article shows that the occurrence of macroscopic flow configuration is a universal natural phenomenon that can be explained and predicted on the basis of a principle of physics (the constructal law): "For a flow system to persist in time

First and second law analysis applied to building envelope: A theoretical approach on the potentiality of Bejan’s theory

open access: yesEnergy Reports, 2015
Especially in the last decade, efforts have been made in developing the sustainable building assessment tools, which are usually performed based on fundamentals of the First Law of Thermodynamics.

Geometric optimization of bodies submitted to an intense heat flux using bifurcated channel nets

open access: yesVetor, 2010
The present work studies the geometric optimization of a body submitted to intense heat flux. The body to be optimized is refrigerated by a ducts system whose circulating fluid will remove the heat.

Survival by Race and Ethnicity in Children and Adolescents/Young Adults With Relapsed/Refractory Hodgkin Lymphoma: A Pooled Analysis of Children's Oncology Group Trials

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Despite 5‐year survival rates of over 90% among children and adolescents/young adults (CAYAs) with classic Hodgkin lymphoma (cHL), 15%–20% relapse after frontline therapy. Prior analysis of frontline Children's Oncology Group (COG) clinical trials demonstrated that, despite similar rates of relapse, non‐Hispanic Black (NHB) and ...
