Rasch Analysis of the Q-CHAT in Colombian Toddlers with Autism Spectrum Disorder
(Springer New York LLC, 2019)
The objective of this study was the validation of the Colombian version of The Quantitative Checklist for Autism in Toddlers (Q-CHAT) by means of the Rasch Rating Scale Model. The Q-CHAT was applied to parents of 100 ...
An infinite family of relativistic magnetized finite thin disks
(Institute of Physics Publishing, 2011)
An infinite family of relativistic finite thin disk model with magnetic field is presented. The model is obtained for solving the Einstein-Maxwell equations for static spacetimes by means of the Horsk-Mitskievitch generating ...

Flexible Liquid Crystal Polymer based complementary split ring resonator loaded quarter mode substrate integrated waveguide filters for compact and wearable broadband RF applications
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper the flexible Liquid Crystal Polymer (LCP) substrate is used to implement broadband wearable/foldable conformal bandpass filters that use compact cavity resonators working under the principle of quarter mode ...
Wireless passive sensing application using a cavity loaded evanescent mode half mode substrate integrated waveguide resonator
(2011)
In this work, an evanescent mode half mode substrate integrated waveguide (HMSIW) resonator is designed for a wireless passive sensing application at 5 GHz. The wireless pressure sensor has been implemented by placing a ...
Object-oriented mathematical modeling for estimating electric vehicle’s range using modelica
(Springer Verlag, 2018)
Electric vehicles (EVs) offer a great alternative for decarbonizing the transport sector. However, insufficient recharging infrastructure and limited range increase the driver’s ‘range anxiety’. Furthermore, the autonomy ...
SIDS-DDoS, a Smart Intrusion Detection System for Distributed Denial of Service Attacks
(Springer, 2020)
In the last few years, the Digital Services industry has grown tremendously, offering numerous services through the Internet and using a recent concept or business model called cloud computing. For this reason, new threats ...
HoloEasy, a web application for computer generated holograms
(Springer Verlag, 2018)
If the appropriate phase and/or amplitude profile is placed on a Diffractive Optical Element (DOE) it can practically generate an image of an object (hologram) by diffraction of the light. The problem of generating computer ...
