Newman–Janis Ansatz in conformastatic spacetimes
(Springer New York LLC, 2016)
The Newman–Janis Ansatz was used first to obtain the stationary Kerr metric from the static Schwarzschild metric. Many works have been devoted to investigate the physical significance of this Ansatz, but no definite answer ...
Background intensity removal in Fourier transform profilometry: A comparative study
(OSA - The Optical Society, 2016)
We study the removal of the background intensity of fringe patterns via Empirical Mode Decomposition and the Hilbert Transform. Simulation results show that the latter provides a suitable background compensation with minimal ...
Performance analysis of a microstrip patch antenna loaded with an array of metamaterial resonators
(Institute of Electrical and Electronics Engineers Inc., 2016)
An analysis of the electrical performance of a microstrip patch antenna loaded with a periodic array of metamaterial resonators is presented in this work. Hexagonal complementary split ring resonators (CSRRs) are selected ...
On the computation of LFSR characteristic polynomials for built-in deterministic test pattern generation
(IEEE Computer Society, 2016)
In built-in test pattern generation and test set compression, an LFSR is usually employed as the on-chip generator with an arbitrarily selected characteristic polynomial of degree equal, according to a popular rule, to ...
In-Substrate Resonators and Bandpass Filters with Improved Insertion Loss in K-Band Utilizing Low Loss Glass Interposer Technology and Superlattice Conductors
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this work, we report on in-substrate passive components using a high performance glass interposer and through glass via (TGV) technology and a multi-layer superlattice conductor architecture. Minimal RF loss is achieved ...
Experimental investigation of high-speed melt spinning by means of digital image analysis
(OSA - The Optical Society, 2016)
We carry out an experimental characterization via high-speed camera of Chill-Block Melt Spinning process by means of digital optical flow for melt ejection velocity calculation and temperature measurement. © OSA 2016.
A boundary element method formulation for modal analysis of doubly curved thick shallow shells
(Elsevier Inc., 2016)
The study of vibrations of shells is an important aspect in the design of thin-walled structures. In general, analytical solutions for the natural frequencies of shells are not possible, and computational techniques are ...
Corrosion failure assessment on AISI 310s steel used as support of refractory concrete panels in a clinker cooler
(Universidad Simon Bolivar, 2016)
This article presents the corrosion failure assessment on AISI 310 Steel, used as support of refractory concrete panels in a Clinker cooler under a combination of high temperatures and atmospheres with high concentration ...
Multi-output model with box-jenkins operators of quadratic indices for prediction of malaria and cancer inhibitors targeting ubiquitin-proteasome pathway (UPP) proteins
(Bentham Science Publishers B.V., 2016)
The ubiquitin-proteasome pathway (UPP) is the primary degradation system of short-lived regulatory proteins. Cellular processes such as the cell cycle, signal transduction, gene expression, DNA repair and apoptosis are ...
Linear model to estimate the degradation index on the processing of recycled polypropylene due to the addition of stabilizer
(Universidad de Tarapaca, 2016)
In the present research work, a lineal model to estimate the Processing Degradation Index (PDI) of polypropylene from recycled industrial waste and municipal solid waste is presented. According to the previous thing an ...
