Microwave characteristics of sol-gel based Ag-doped (Ba 0.6Sr0.4)TiO3 thin films
(Elsevier, 2014)
Dielectric Ba0.6Sr0.4TiO3 (BST) thin films with a different concentration of Ag-dopant of 0.5, 1, 1.5, 2, 3, and 5 mol % have been prepared using an alkoxide-based sol-gel method on a Pt(111)/TiO 2/SiO2/Si substrate and ...
Vibrational response of elastic membranes coupled to acoustic fluids using a BEM–BEM formulation
(Springer New York LLC, 2014)
In the last two decades, few works have been reported in the literature related to analysis of fluid–structure interaction problems using Boundary Element Method for modeling both structure and fluid. To the author’s ...
Vibration analysis of shear deformable shallow shells using the Boundary Element Method
(2014)
In this work, the modal and harmonic analysis of elastic shallow shells, using a Dual Reciprocity Boundary Element formulation, is presented. A boundary element formulation based on a direct time-domain formulation using ...
Boundary element analysis of shear deformable shallow shells under harmonic excitation
(Tech Science Press, 2014)
In this work, the harmonic analysis of shallow shells using the Boundary Element Method, is presented. The proposed boundary element formulation is based on a direct time-domain integration using the elastostatic fundamental ...
Hexagonal filters for ultrasound images
(2014)
Most of the devices for acquisition and display of medical images use rectangular lattices even though there are other sampling strategies that can be more efficient in terms of resolution. This paper proposes an approach ...
Design of an electrogoniometer based on accelerometers for the evaluation of sports gesture in weight lifting
(Institute of Electrical and Electronics Engineers Inc., 2014)
This article describes the design and implementation of an electrogoniometer to measure joint angles during the execution of weight lifting exercises. The electrogoniometer consists of four microelectromechanical accelerometers ...

Thermoeconomic indicators ofair conditioning in a river ship to change the configuration of their thermal insulation
(American Society of Mechanical Engineers (ASME), 2014)
This work has as object of study the energy of a river ship air conditioning system performance, using fiberglass, polyurethane or rockwool as insulation. Thermoeconomics Indicators based on second law of thermodynamics ...
Flexible Liquid Crystal Polymer based complementary split ring resonator loaded quarter mode substrate integrated waveguide filters for compact and wearable broadband RF applications
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper the flexible Liquid Crystal Polymer (LCP) substrate is used to implement broadband wearable/foldable conformal bandpass filters that use compact cavity resonators working under the principle of quarter mode ...
Study of the lower limp's angle during weightlifting exercises using an accelerometer-based system
(Institute of Electrical and Electronics Engineers Inc., 2014)
This article describes the implementation and use of a two-accelerometer system to measure the angle formed between lower joints of weightlifters during the execution of the technical gesture. Being aware of movement between ...
