Equal channel angular sheet extrusion (ECASE) produces twinning heterogeneity in commercially pure titanium
(Elsevier, 2021-11)
Commercially pure grade 2 titanium in sheet form was processed by equal channel angular sheet extrusion (ECASE) up to two passes at room temperature. The ECASE process generated a heterogeneous state of deformation, mainly ...
A statistical study of heterogeneous nucleation of ice by molecular dynamics
(2015)
We studied the stochastic nature of heterogeneous nucleation of supercooled liquid water by molecular dynamics simulations. The systems were composed of 768 molecules; M of them had their positions restricted forming a ...
Dynamic coordination among heterogeneous agents
(2015-03-16)
We study a dynamic model of coordination with timing frictions and payoff heterogeneity. There is a unique equilibrium, characterized by thresholds that determine the choices of each type of agent. We characterize equilibrium ...
Analysis of catalytic potential of a new heterogeneous catalyst in the preparation of biodiesel
(2018-01-01)
In this work was investigated the catalytic potential of a new heterogeneous catalyst of stoichiometry Ca0.5K0.5TiCu0.25O3, with double perovskite structure, in the preparation of biodiesel via ethylic route. The catalyst ...
Improving virtual machine consolidation for heterogeneous cloud computing datacenters
(2019-10-01)
Datacenters in cloud computing systems may consist of thousands of computing nodes and communication devices, requiring virtual machine placement to optimize resources utilization. Heterogeneous environments of current ...
The Role of Heterogeneous Catalysts in Converting Cellulose to Platform Chemicals
(2020-01-01)
In times of rethinking production processes and consumption habits to minimize the effects of global warming, it is crucial to find alternatives that lead to replacing fossil fuels by renewable materials. The development ...
A model for clustering data from heterogeneous dissimilarities
(Elsevier, 2020)
The α and β diversities in the fish assemblages of the promiss̃ao reservoir (SP-Brazil): Scales, complexities and ecotone heterogeneity
(2001-01-01)
This paper characterizes the fish assemblage and its interaction with different ecotones within the reservoir. The transformation of a river basin into a cascade of reservoirs produces new ecotones which interact differentially ...
