Here, an experimental optical setup which integrates the virtues of the digital interferometry ... -
A semi-automatic tool for the connectivity tracking of neuronal processes acquired using electron microscopy
(Public Library of Science, 2015)We describe an image processing tool for helping to organize, annotate and map neuronal circuitry. The tools use high-resolution images serially acquired via scanning electron microscopy (SEM). First, various image processing ... -
Malware on mobile devices odds of infection based on running operating system version
(Asian Pacific Organization for Cancer Prevention, 2016)The world of mobile devices which have the quality to stay connected to the web is going through a exponential growth, but in parallel with this event, appears the threats with the developing of an equal magnitude, which ... -
Obfuscation procedure based in dead code insertion into crypter
(IEEE, 2016)The threat that attacks cyberspace is known as malware. In order to infect the technologic devices that are attacked, malware needs to evade the different antivirus systems. To avoid detection, an obfuscation technique ... -
Modification of the optical flow horn-schunck estimation incorporating exaustive search
(IEEE, 2016)Optical Flow is the pixels apparent movement pattern of two consecutives images. There are differents methods to estimate the optical flow: variational methods and exaustive methods. Exhaustive methods take a neighborhood ... -
SGSI support throught malware's classification using a pattern analysis
(IEEE, 2016)Nowadays, there are significant amounts of malware codes that are created every day. However, the majority of these samples (malware) are variations of other malware that have been already identified. Therefore, most of ... -
Genotyping and Persistence of Candida albicans from Pregnant Women with Vulvovaginal Candidiasis
(Springer Netherlands, 2017)Objective To study Candida albicans genotypes using RAPD and their susceptibility to fluconazole in healthy pregnant women and in vulvovaginal candidiasis (VVC) patients after topical treatment with clotrimazole. Methods ... -
Down's syndrome, anorectal malformation and Morgagni's hernia: Description of an unusual clinic case
(Via Medica, 2017)Morgagni's hernia is a rare type of congenital diaphragmatic hernia that constitutes less than 5% of congenital diaphragmatic defects. It is moderately associated with congenital anomalies, while it is rarely associated ... -
Real time optical flow estimation for images with large displacements
(2016 IEEE International Conference on Automatica (ICA-ACCA), 2016)Optical flow is defined as the pattern of apparent motion of objects in a image sequence. Optical flow has many applications: control of automatic taking off and landing of an autonomous aircraft, video compression, noise ... -
Matlab programmed method for the optical flow estimation based on the integral image
(IEEE, 2018)The Optical Flow computation is the estimation of the apparent displacement of the object on an image sequence (actual image and next image). There are different methods for Optical Flow estimation, standing out exhaustive ... -
Obfuscation procedure based on the insertion of the dead code in the crypter by binary search
(IEEE, 2018)What threatens the cyberspace is known as malware, which in order to infect the technological devices, it has to be capable of bypassing the antivirus motor. To avoid the antivirus detection, the malicious code requires ... -
Implementation of an emitting LED circuit in a Visible Light communications positioning system
(2018)In this paper, two LED emitting circuits are implemented in a VLC positioning system, a regular Bias-Tee and a circuit proposed by Ghassemlooy, aiming to provide the system with portability and functionality. For this, an ... -
Simultaneous optical flow and occlusion estimation for images with large displacements
(IEEE, 2017)In this paper we present a method for estimating occlusion of pixels in image sequences. The estimation of the occlusion layer is based on optical flow. In our proposal the optical flow is computed in an exhaustive way by ... -
Evidence-based guidelines for the use of tracheostomy in critically ill patients
(Elsevier, 2017)Objectives: To provide evidence-based guidelines for tracheostomy in critically ill adult patients and identify areas needing further research. Methods: A taskforce composed of representatives of 10 member countries of the ... -
Oral literacy demand in the pediatric dental clinic: a pilot study
(Wiley, 2017)Background. The parent's ability to obtain, process, and understand important oral health information (i.e., their oral health literacy) is directly related to their child's oral health status. Aim. To assess the relationship ... -
De lo popular a lo masivo: La Revolución mexicana en el cine de la época de oro (1936-1959)
(Universidad de la Frontera, 2018)En este texto planteamos que las representaciones de la revolución mexicana en el cine de la época de oro muestran un conjunto de racionalidades y discursos que legitiman una visión ordenada e higienizada de la revolución. ... -
