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 ... -
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 ... -
GridUI, a RESTful web service and ubiquitous UI for accessing HPC resources
(Institute of Electrical and Electronics Engineers Inc., 2016)This paper describes the design of a user interface between a high-throughput computing pool system like HTCondor and a device-independent user interface. This design aims to bring parallel tools and resources to a novel ... -
Composite Likelihood Inference for Multivariate Gaussian Random Fields
(Springer New York LLC, 2016)In the recent years, there has been a growing interest in proposing covariance models for multivariate Gaussian random fields. Some of these covariance models are very flexible and can capture both the marginal and the ... -
Background intensity removal in structured light three-dimensional reconstruction
(Institute of Electrical and Electronics Engineers Inc., 2016)In Fourier Transform Profilometry, a filtering procedure is performed to separate the desired information (first order spectrum) from other unwanted contributions such as the background component (zero-order spectrum). ... -
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 ... -
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 ... -
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 ... -
Speckle free optical watermarking based on pseudo-random phase encoding
(Institute of Electrical and Electronics Engineers Inc., 2016)Watermarking is a process of embedding copiright information into an image to verify the ownership without any kind of corruption. In optical applications, the usage of diffusers is required to obtain a homogeneously ... -
Robust adaptive control of a planar 3RRR parallel robot for trajectory-tracking applied to crouch gait cycle in children with cerebral palsy
(Institute of Electrical and Electronics Engineers Inc., 2019)This paper presents the modelling, control and simulation of a 3RRR planar parallel robot, using a robust adaptive control strategy. The objective of this work is to achieve the control over desired trajectory-tracking of ... -
On the compensation of uneven illumination in retinal images for restoration by means of blind deconvolution
(Institute of Electrical and Electronics Engineers Inc., 2016)Retinal eye fundus images are used for diagnostic purposes, but despite controlled conditions in acquisition they often suffer from uneven illumination and blur. In this work, we propose the use of multi-channel blind ... -
Autonomía profesional y riesgos de seguridad de los periodistas en Colombia
(Flacso Mexico, 2017)This paper analyzes the relationship between professional autonomy and security risks of journalists in Colombia. A correlational-transversal research was conducted with a sample of 751 journalists who filled out the ... -
