Machine learning (ML) and deep (DL) for big data (BD) management are currently viable approaches that can significantly help in high-temperature materials design development. ML-DL accumulate knowledge by from existing generated through multi-physics modelling (MPM) experimental tests (ETs). DL mainly involves analyzing nonlinear correlations high-dimensional datasets implemented specifically d...

Este trabalho apresenta o resultado de pesquisas sobre Turismo Base Comunitária (TBC) e sua presença repercussão no litoral sete dos nove estados que compõe Nordeste brasileiro, tendo como objetivo identificar, caracterizar mapear as iniciativas TBC ocorrem nos municípios litorâneos nordestinos do Maranhão a Alagoas. Como metodologia, além da pesquisa bibliográfica às temáticas relacionadas ao ...

Thermal barrier coating are perceived as an enabling technology to increase the performance of, improve efficiency within, and lower the emissions from, modern gas turbines. To fully utilise this capability one has to be able to accurately predict the life of these coatings under conditions relevant to gas turbine service. This paper addresses the failure of TBC systems as a result of erosion a...

Transparent boundary conditions (TBCs) for general Schrödinger– type equations on a bounded domain can be derived explicitly under the assumption that the given potential V is constant on the exterior of that domain. In 1D these boundary conditions are non–local in time (of memory type). Existing discretizations of these TBCs have accuracy problems and render the overall Crank–Nicolson finite d...

This paper describes a new multilayer TBC that incorporates a 10 μm-thick oxygen barrier layer of yttrium–aluminum garnet (YAG) into a typical YSZ TBC system. The thermal conductivity of as-sprayed YAG/YSZ coatings was reduced due to excessive porosity and amorphous areas in the YAG layer. After long-term heat treatments, the conductivity of the multilayer was unaffected by the presence of YAG....

The response function F is expressed in terms of tbc Green function of the unperturbed system and attention is then focussed on two taxes: (i) A perfect periodic metal crystal, pert&d by V. (ii) A metal lattice with a surface in which V is embedded. A full discusxion is given of tbc inRucnce.of Fermi sutface topology on the anisotropy of Ap in the asymptotic n&m far from the defect. Provided V(...

Aims: Stethoscopes represent a vehicle of bacteria and other microorganisms and may play a role in the spread of health-care associated infections (HAIs). We aimed to evaluate the contamination levels of stethoscopes before and after use of a disinfecting technique (DT).

INTRODUCTION Thyroid hormones (TH) may affect bone metabolism and turnover, inducing a loss of bone mass among hyperthyroid and in hypothyroid patients under hormone replacement treatment. Thyroid dysfunction leads to changes in the dynamics of parathyroid hormone (PTH) and calcitonin (CT) secretion. OBJECTIVE The objective of the study was to determine the usefulness of CT as adjuvant therap...

The objective of this study was to mimic the microstructure of MCrAlY coatings sprayed using HVOF (High Velocity Oxy-Fuel) processes by using an Air Plasma Spray (APS) process in order to improve oxidation and spallation life of MCrAlY APS coatings. Figure 1 shows the typical microstructures obtained when spraying bond coats using the (a) HVOF process, and (b) the APS process. The microstructur...
