Improving elevation resolution in phased-array inspections for NDT
(Elsevier, 2019-01)
The Phased Array Ultrasonic Technique (PAUT) offers great advantages over the conventional ultrasound technique (UT), particularly because of beam focusing, beam steering and electronic scanning capabilities. However, the ...
Design and testing of a microelectrode array with spatial resolution for detection of cancerous cells in mixed cultures
(IOP Publishing, 2019-10)
We present the design, construction and testing of a microelectrode array with spatial resolution which can be used for the detection of cancerous cells in a mixed cell culture by means of the impedance spectroscopy ...
Chemometric tools improving the determination of anti-inflammatory and antiepileptic drugs in river and wastewater by solid-phase microextraction and liquid chromatography diode array detection
(Elsevier Science, 2009-07)
An analytical method for the simultaneous determination of seven non-steroidal anti-inflammatory drugs (naproxen, ketoprofen, diclofenac, piroxicam, indomethacin, sulindac and diflunisal) and the anticonvulsant carbamazepine ...
The Cherenkov Telescope Array: an advanced facility for the Ground-based High Energy Gamma Ray Astronomy.
(Asociacion Argentina de Astronomia, 2013)
In the past 15 years, Very High Energy (VHE) γ-ray ex-periments as H.E.S.S., MAGIC and VERITAS have been very successfulunveiling the mysteries of the non thermal Universe using Cherenkovtelescopes based on Earth. The next ...
Técnicas de algoritmos genéticos aplicadas à otimização do diagrama de radiação de arranjo de antenas
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2014-07-07)
Nowadays the search for optimization becomes stronger day by day. Furthermore,
genetic algorithms have been widely studied by researchers, since they act as stochastic optimization
process which can be applied in many ...
Localization with multicomponent seismic array
(Institute of Electrical and Electronics Engineers, 2011)
Seismo-volcano source localization is essential to improve our understanding of volcano systems. The lack of clear seismic wave phases prohibits the use of classical location methods. Seismic antennas composed of one-component ...
Lamb mode diversity imaging fornon-destructivetesting of plate-likestructures
(London, 2014-02-24)
Several Lamb wave modes can be coupled to a particular structure, depending on its geometry and transducer used to generate the guided waves. Each Lamb mode interacts in a particular form with different types of defects, ...
The MPI-SOUSY-VHF Radar at Jicamarca: high altitude-resolution capabilities
(Instituto Geofísico del Perú, 2007)
The MPI-SOUSY radar has been moved from its original location at the Harz Mountains, Germany, to the Jicamarca Observatory. Two main modifications have been made to the system: 1) The antenna array now consist of 126 Yagis ...
