Desarrollo de algoritmos de phase-shifting con pasos arbitrarios

En las últimas décadas, técnicas como la interferometría, la perfilometría por proyección de franjas o la deflectometría se han transformado en herramientas indispensables para la ciencia y la ingeniería. Estas técnicas tienen en común que la información buscada se encuentra en la fase de un patrón de franjas bidimensional. De las varias técnicas que existen para la extracción de la fase de los patrones de franjas, en la presente tesis se estudia el método conocido como phase-shifting. Nuestro objetivo central fue el desarrollo de algoritmos de phase-shifting con pasos arbitrarios. Se desarrollaron algoritmos para superar diferentes fuentes de error como por ejemplo la presencia de armónicos, la mala determinación del desplazamiento asociado a cada imagen o la presencia de ruido aleatorio en las imágenes. En el desarrollo de este trabajo, se obtuvo también un algoritmo que permite determinar el desfasaje entre interferogramas consecutivos cuando dicho desfasaje no es conocido, permitiendo recuperar la fase asociada a un sistema sin necesidad de calibrarlo. Por último, con el objetivo de estudiar la calidad de los datos adquiridos, se propuso un procedimiento para determinar el contraste en el caso de interferogramas arbitrariamente desfasados. En todos los casos se presentaron simulaciones y resultados experimentales.In recent decades, techniques such as interferometry, fringe projection profilometry or deflectometry have become indispensable tools for science and engineering. These techniques have in common that the information sought is in the phase of a two-dimensional fringe pattern. Of the various techniques that exist for the extraction of phase from fringe patterns, the method known as phase-shifting is studied in this thesis. Our main objective was the development of phase-shifting algorithms with arbitrary steps. The algorithms were developed to overcome different sources of error such as the presence of harmonics, the poor determination of the displacement associated with each image or the presence of random noise in the images. In the development of this work, we also obtained an algorithm that allows to determine the phase change between consecutive interferograms when the phase change is unknown, allowing the phase associated with a system to be recovered without needing to calibrate it. Finally, to study the quality of the acquired data, a procedure was proposed to determine the contrast in the case of arbitrarily displaced interferograms. Simulations and experimental results were presented in all cases

How Risky People of Getting COVID-19 based on Their Daily Activities?

In Indonesia at the end of 2020, COVID-19 cases were increasing and predicted to continue, as it had not yet passed the peak of the pandemic curve. The government had implemented mobility restrictions to reduce exposure to COVID-19. This study aimed to identify the risk of people getting COVID-19 based on their daily activities. Using a cross-sectional design, this study took 315 respondents under non-probability sampling from September to October 2020. Thedata were analyzed using the Chi-square test with α 0.05. This study showed that the risk percentage of people infected with COVID-19 based on their daily activities was 15.56% at low-risk, 63.81% at moderate-low risk, 17.14% at moderate risk, and 3.9% at moderate-high risk. Factors that were significantly related to the risk of getting COVID-19 in terms of daily activities were sex, attitude, and COVID-19 preventive behavior. In brief, the risk of getting COVID-19 could be assessed from daily activities carried out during the pandemic's peak

Smoking status in Iranian male adolescents: A cross-sectional study and a meta-analysis

The present study aimed to estimate the prevalence of smoking status and its associated factors in Iranian adolescents and a meta-analysis of recent cross-sectional studies in order to estimate the corresponding prevalence for all Iranian adolescents. In a cross-sectional study, 1064 male high school students in Zanjan city (northwest of Iran) were recruited. A self-administered questionnaire was used for smoking status and associated factors. Through the meta-analysis, all relevant published studies were reviewed. Almost one-third of adolescents (34.2, n =354) have experienced smoking either experimentally (23.4, n=242), or regularly (10.8, n=112). Multivariate analysis showed that older age (OR = 1.20; 95 CI: 1.05-1.37), risky behaviors (OR=1.83; 1.25-2.68), Tramadol medication (OR = 2.19; 1.54-3.11), low self-esteem (OR 1.07; 1.03-1.11), positive attitude toward smoking (OR= 1.15; 1.09-1.21), positive thinking about smoking (OR= 1.07; 1.01-1.14) and having smoker friends (OR= 1.94; 1.36-2.77) were significantly associated with cigarette smoking in adolescents. Meta-analysis results showed that 7 of Iranian adolescents are regular smokers and 27 are experimenters. Increasing prevalence of smoking in Iranian adolescents is a major concern for public health. Controlling risky behaviors and increasing health education are recommended. (C) 2013 Elsevier Ltd. All rights reserved

Discrete Model of Ideological Struggle Accounting for Migration

A discrete in time model of ideological competition is formulated taking into account population migration. The model is based on interactions between global populations of non-believers and followers of different ideologies. The complex dynamics of the attracting manifolds is investigated. Conversion from one ideology to another by means of (i) mass media influence and (ii) interpersonal relations is considered. Moreover a different birth rate is assumed for different ideologies, the rate being assumed to be positive for the reference population, made of initially non-believers. Ideological competition can happen in one or several regions in space. In the latter case, migration of non-believers and adepts is allowed; this leads to an enrichment of the ideological dynamics. Finally, the current ideological situation in the Arab countries and China is commented upon from the point of view of the presently developed mathematical model. The massive forced conversion by Ottoman Turks in the Balkans is briefly discussed.Comment: 24 pages, with 5 figures and 52 refs.; prepared for a Special issue of Advances in Complex System

Epidemiological Patterns of Road Traffic Crashes During the Last Two Decades in Iran: A Review of the Literature from 1996 to 2014

Context: Despite considerable attention given to health statistics of road traffic crashes (RTCs), the epidemiological aspects of injuries resulting from RTCs are not fully understood in Iran and other developing countries. The aim of this review was to study the epidemiological pattern and issues arising due to RTCs in Iran. Evidence Acquisition: The scope of this study involves data from a broad range of published literature on RTCs in Iran. Data collection for this study was conducted by searching for keywords such as traffic accidents, traffic crashes, motorcycle accidents, motorcycle crashes, motorcycle injury, motor vehicle injury, motor vehicle crashes and motor vehicle accidents, Iran and Iranian in various databases such as Embase, PubMed, Google Scholar, Scopus, Magiran, Iranian scientific information database (SID) and IranMedex. Results: This study comprised of 95 articles. It is evident from this review that a large number of severe RTCs occur due to collision of two or more vehicles and most of the victims are males aged between 30 and 39 years. Male pedestrian, drivers and passengers are more likely to be severely injured in comparison to females. One of the most prevalent causes of death among adults involved in the RTCs are head injuries and the majority of deaths occur prior to hospitalization. Mortality rates for RTCs are higher in summer, especially during midnight among all age groups. The most common individual and environmental risk factors associated with RTCs include lack of attention, getting trapped in the car, listening to music, fatigue and sleepiness, duration and distance and negligence of seatbelt usage while driving. Conclusions: The findings of the current study will be beneficial in prevention of RTCs and its associated complications and hence will be vital for policy makers, health service managers and stakeholders
