Fabricação de um dinamômetro para medição de força no corte ortogonal
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Mecânica, 2019-06)
This work aimed to design and manufacture a dynamometer for measuring
the force components in orthogonal cutting (cutting and feed forces). The design
was based on 50 kgf load cells and on the Arduino platform. It was ...
Vibrational study of N-phenyl-substituted hydroxynaphthylaldiminate copper(II) complexes
(1993)
The infrared spectra of seven bis(N-phenyl-substituted hydroxynaphthylaldiminate) complexes of Cu(II) were scanned from 4000 to 100 cm-1. Particular emphasis is given to the low-energy region. The assignment of the chelate ...
Gender Policies and Armed Forces in Latin America's Southern Cone
(Geneva School of Governance, 2015-09)
In Latin America´s Southern Cone, particularly in Argentina, the socio-professional integration of women into the Armed Forces was narrowly geared to a specific scenario : human rights enlargement. Its general inspiration ...
Superdiffusion induced by a long-correlated external random force
(American Physical Society, 2011-12)
We consider a particle immersed in a thermal reservoir and simultaneously subjected to an external random force that drives the system to a nonequilibrium situation. Starting from a Langevin equation description, we derive ...
An RVE-based multiscale theory of solids with micro-scale inertia and body force effects
(Elsevier, 2015-01)
A multiscale theory of solids based on the concept of representative volume element (RVE) and accounting for micro-scale inertia and body forces is proposed. A simple extension of the classical Hill–Mandel Principle together ...
Polyfuran-based chemical sensors: Identification of promising derivatives via DFT calculations and fully atomistic reactive molecular dynamics
(2020-12-05)
Organic polymers are promising materials for the design of active layers of chemical sensors. In this context, polyfuran (PF) derivatives have not been largely investigated, mainly due to stability problems and poorer ...
Identification of the tension force in cables with insulators
(Springer, 2019-01-09)
The present paper explores two approaches which, based on the measurement of the two first natural frequencies, allow the identification of the tension force in cables with insulators. For this purpose, the nonlinear ...
General valence force field and molecular dynamic parameters for cubic lanthanide hexachloro-elpasolite crystals
(1988)
A normal coordinate analysis has been carried out for the series Cs2NaLnCl6, where Ln represent a trivalent lan thanide cation such as Pr+ 3, Sm+3, Eu+3, Tb+ 3, Ho+3and Tm+3by using a general valence force field (GVFF). A ...
