Effects of intergranular barrier fluctuations on the electrical conductivity of polycrystalline semiconductors
(Elsevier Science, 2018-11-15)
We studied the influence of intergranular barrier fluctuations on the electrical response of 3D semiconductor polycrystals. We first computed with a numerical simulation model the dispersion in the intergranular barrier ...
Effects of intergranular capacitance and resistance dispersion on polycrystalline semiconductor impedance
(Elsevier Science, 2019-12)
In the present work we focused on the effects, often disregarded, of the intergranular barrier fluctuations on the total impedance of polycrystalline structures. These fluctuations come from the discreteness nature and ...
Desenvolvimento de uma nova ferramenta para a alvenaria: o gabarito facilitador
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia CivilUTFPR, 2021-12-13)
The mortared ceramic block masonry system is a process widely used for the manufacture of vertical seals in Brazil. The present work aims to develop a new tool regarding the perceptions of the civil construction workforce, ...

Uso de redes neuronales artificiales en el cálculo de la distorsión de entrepiso en edificaciones de albañilería confinada, Lima - 2022
(Universidad Privada del NortePE, 2023-07-03)
Uno de los problemas más conocidos al momento de hacer el análisis estructural de una edificación de albañilería confinada es lo largo e iterativo que son los procesos de cálculo, por esta razón en esta investigación se ...
Phase stability and properties of Bi6Te2O13+delta (delta=0 or 2)
(Elsevier B.V., 2021-03-15)
The crystalline Bi6Te2O15 and Bi6Te2O13 phases with orthorhombic and cubic symmetries, respectively, were synthesized by solid-state reaction synthesis. A study of the thermal stability of both phases was carried out, being ...
Análisis Comparativo de Residuos de Construcción Generados en un mismo Modelo de Vivienda con Sistema Tradicional vs. Diseño Modular
(Instituto Tecnológico de Costa Rica, 2012)
In many projects, specially in dwellings
construction, the traditional system involves to
build with Patarrá blocks and concrete columns;
this situation has produce a lot of waste which are
not quantified. In response, ...
