Fracture analysis in 5HS carbon composites subjected to pure modes I and II fatigue induced delamination
(2014-01-01)
Interlaminar fracture process in woven composite laminate in general takes place in a nonlinear front propagation when analyzing a 2-D propagation for mode I opening. The nonlinearity is justified by the arresting crack ...
Operational safety on subsea wells
(2011-07-18)
Supported by the last events, it can be observed that safety must be the major concern in the activities developed in oil and gas well construction. However, safety assessment during the well construction process is not a ...
Finite element with embedded discontinuities analysis of well production decline due to fracture closure in naturally fr
(2018-01-01)
In naturally fractured reservoirs, the fractures may represent the main pathway for fluid flow. Therefore, the magnitude of fracture permeability plays a fundamental role in the productivity of such type of reservoir. In ...
New improved version of J1…J4 interferometry method and its application to nanometric vibration measurements
(IEEERio de Janeiro, 2013)
Piezoelectric ceramics, such as PZT, can generate subnanometric displacements, but in order to generate multi-micrometric displacements, they should be either driven by high electric voltages (hundreds of volts), or operate ...
Thermodynamic properties applied to the sorption isotherms of kiwifruit
(Isnt Tecnologico Veracruz, 2001-01-01)
The net isosteric heat and entropy of water sorption were calculated for kiwifruit, based on sorption isotherms obtained by the static gravimetric method at different temperatures (20 to 70 degreesC). The Guggenheim-Ande ...
Mining software repository to identify crosscutting concerns using combined techniques
(2013-01-01)
Modularization is a goal difficult to achieve in software development. Aspect mining aims to identify crosscutting concerns in non aspect oriented software allowing organizing them into aspects and, thus, improve the ...
Fault Detection in Transmission Towers Using State Observers
(2021-01-01)
Over the years, the demand for tools that facilitate the analysis of static and dynamic systems only increases, and the fidelity of the results obtained with these tools is also another point of interest. The present work ...
Investigating multipath mitigation for kinematic applications using wavelet techniques
(2008-03-20)
Multipath is the phenomenon that occurs when the signal from GNSS satellites reflects on objects surrounding the survey environment and reaches the receiver's antenna through multiple paths. Usually, the receiver collects ...
