1. ECONOMIC RESILIENCE AND CROWDSOURCING PLATFORMS
ABSTRACT The increased interdependence and complexity of modern societies have increased the need to involve all members of a community into solving problems. In times of great uncertainty, when communities face threats of different kinds and magnitudes, the traditional top-down approach where government provides solely for community wellbeing is no longer p

2. Una introducción a la derivada desde la variación y el cambio: resultados de una investigación con estudiantes de primer año de la universidad
The study of calculus plays an important role when it is necessary to quantify or measure any phenomenon. However, in general, in the educational system, formal construction processes and algorithmic aspects have been prioritized. Seeking to answer this problem, an investigation addressing the study of the derivative was started. The work was framed from the

3. Mechanical evaluation of space closure loops in Orthodontics
This study evaluated the mechanical performance of teardrop-shaped loops and teardrop-shaped loops with helix used in orthodontic space closure. Sixty retraction loops made with 0.019" x 0.025" stainless steel (SS) and beta-titanium (BT) wires were used. They were attached to a testing machine to measure the magnitudes of the sagittal force and the load-defl

4. Stochastic texture analysis for measuring sheet formation variability in the industry
Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced and the manufacturing processes involved. However, it is often difficult to measure objectively the similarity among such industrial stocha

5. Essays on decision sciences: exploring cognition, information processing, and complexity
This thesis provides three original contributions to the field of Decision Sciences. The first contribution explores the field of heuristics and biases. New variations of the Cognitive Reflection Test (CRT--a test to measure "the ability or disposition to resist reporting the response that first comes to mind"), are provided. The original CRT (S. Frederick [

6. La engañosa simplicidad del "método de Stokes" para medir viscosidades
In this article we focus on the relation between magnitudes used to measure liquid viscosity coeficients with Stokes’ method. The related experiment is a low-cost, and apparently also a very simple one. Its simplicity however rests on the exacting conditions that must be fulfilled by the system. Otherwise, it is incorrect to assume the validity of the

7. 3D image registration of the human brain / Registro de imagens 3D do cerebro humano
Image Registration is the process that aligns two or more images in a common reference system of spacial coordinates [31]. It is an important problem with several applications in Medical Imaging, enabling, for instance, the analysis of changes in anatomy along time by the registration of images from the same modality, and the study of combined anatomic and p

8. Définition et implémentation des corrections instrumentales de la mission spatiale CoRoT
CoRoT (Convection, Rotation and planetary Transits) is a space mission conceived to the stellar seismology and the search of extra solar planets. Both scientific programs are based on very high precision photometry and require long and uninterrupted observations. For the study of the stellar oscillations, the instrument must be able to measure periodic varia

9. A concepção de educação matemática de Henri Lebesgue
The main aim of this study was to consider the aspects which characterises Henri Lebesgues conception of Mathematics Education. Lebesgue (1875-1941), as well as being one of the most eminent mathematicians of the twentieth century and revolutionising Mathematical Analysis with the creation of a new theory of measure and hence a new definition of the integral

10. DESENVOLVIMENTO DE UM SISTEMA DE PEDAIS DINAMOMÉTRICOS PARA AVALIAÇÃO BIOMECÂNICA NO CICLISMO / DEVELOPMENT OF A DYNAMOMMETER PEDALS SYSTEM FOR CYCLING BIOMECHANICS EVALUATION
The assessment of pedal forces is one of the more sophisticated methods applied on the sports sciences to accomplish cycling performance tests. With information of pedal forces the pedaling technique is evaluated based on the ability of the cyclists to produce and apply forces on the pedals. Several variables concerning the performance can be monitored with

The characteristics of lightning currents have a fundamental importance on insulation coordination and on the design of transmission and distribution lines equipment. The CIGRE cumulative frequency distribution curves relative to the main parameters of the first and subsequent downward flashes, which are very frequently used for the evaluation of the lightni

12. INTERROGATION SYSTEM OF FIBER BRAGG GRATING SENSORS USING TIME DIVISION MULTIPLEXING AND WAVELEGHT DIVISION MULTIPLEXING / SISTEMA DE INTERROGAÇÃO DE SENSORES A REDE DE BRAGG UTILIZANDO MULTIPLEXAÇÃO NO TEMPO E MULTIPLEXAÇÃO NO COMPRIMENTO DE ONDA
An interrogation system of fiber Bragg grating sensors using time division multiplexing and wavelength division multiplexing is proposed and demonstrated. The system presents a solution to measure the magnitudes associated to the reflection spectrum of the fiber Bragg gratings, making possible to increase the number of the Bragg gratings sensors monitored th
