Microscopic shape from focus using white light interferometric fringes
(OSA - The Optical Society, 2018)In this work we study the use of a focus measure to improve the 3D reconstruction of low reflectivity microscopic samples using white light interference microscopy. Simulation and experimental results show the improved ... -
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 ... -
Millimeter-wave bandpass filter on LCP using CSRR-loaded triangular-shape quarter-mode substrate integrated waveguide
(John Wiley and Sons Inc., 2015)A millimeter-wave two-pole bandpass filter (BPF) with an asymmetrical frequency response is realized on a flexible liquid crystal polymer substrate for wearable/conformal wireless applications. The design uses the ... -
Mitochondrial DNA analysis suggests a chibchan migration into Colombia
(Pontificia Universidad Javeriana, 2015)The characterization of mitochondrial DNA (mtDNA) allows the establishment of genetic structures and phylogenetic relationships in human populations, tracing lineages far back in time. We analysed samples of mtDNA from ... -
Mixed-integer programming model for transmission network expansion planning with Battery Energy Storage Systems (BESS)
(Cartagena de Indias, 2020-08-25)This article assesses the costs and benefits of incorporating battery energy storage systems (BESS) in transmission network expansion planning (TEP) over multiple time periods. We propose a mixed-integer programming model ... -
