1. Assessing Water Erosion Processes in Degraded Area Using Unmanned Aerial Vehicle Imagery
ABSTRACT The use of Unmanned Aerial Vehicles (UAVs) and Structure from Motion (SfM) techniques can contribute to increase the accessibility, accuracy, and resolution of Digital Elevation Models (DEMs) used for soil erosion monitoring. This study aimed to evaluate the use of four DEMs obtained over a year to monitor erosion processes in an erosion-degraded ar

2. A short remark on the modelling of a three-story shear-building structure
Abstract In this note, some remarks on the modelling of a multi-degree-of-freedom system, a three-story shear-building structure, is presented. The modelling of a mechanical system is one of the most important aspects in engineering and physics, since is crucial for the understanding of the system. Besides, the model, if properly made, can be also useful to

3. Mechanics of Cable-Suspended Beams
Abstract The cable-suspended bridges differ from the elastic structures because of the inherent nonlinearity of the suspension cables. The primary focus of the available theories is to investigate the effect of nonlinearities associated with the distributed self-weight of the cable and its finite elastic displacements. The main point of departure of this pap

4. Finite element analysis of high modal dynamic responses of a composite floor subjected to human motion under passive live load
Light weight and long span composite floors are common place in modern construction. A critical consequence of this application is undesired vibration which may cause excessive discomfort to occupants. This work investigates the composite floor vibration behavior of an existing building based on a comprehensive study of high modal dynamic responses, the rang

5. Odometria visual baseada em técnicas de structure from motion
Odometria Visual é o processo pelo qual consegue-se obter a posição e orientação de uma câmera, baseado somente em imagens e consequentemente, em características (projeções de marcos visuais da cena) nelas contidas. Com o avanço nos algoritmos e no poder de processamento dos computadores, a subárea de Visão Computacional denominada de Structure f

6. Self-Tuning Multimodal Piezoelectric Shunt Damping
Piezoelectric shunt damping is a well known structural vibration control technique that consists in connecting an electrical circuit to a piezoelectric transducer attached to the structure. In the case of a resonant shunt, the network consisting of an inductor-resistor network when combined with the capacitive nature of the piezoelectric transducer impedance

8. MARRT Pipeline:pipeline for markerless augmented reality systems based on real-time structure from motion / MARRT Pipeline:pipeline for markerless augmented reality systems based on real-time structure from motion
Nowadays, with the increase of computational power and the studies on usability, real-time systems and photo-realism, the requirements of any computer system are more complex and sophisticated. Augmented Reality systems are not an exception in their attempt for solving users‟ real life problems with reduced risk, time expending or learning complexity.

9. Comparison of different identification techniques of vertical structural dynamics of twin-wheeled telescopic landing gear.
The main purpose of this work is to model dynamically the latero-torsional response of the structure of a landing gear using identification techniques. The emphasis is placed on identifying this motion on aircraft twin-wheeled telescopic main landing gears. Between the many possible model structures, a linear polynomial ARX and ARMAX model structures and a s

11. Uma investigação sobre a aplicabilidade da teoria de sistemas não-ideais a fundações de máquinas reais. / An investigation on the applicability of the non-ideal systems theory to real machine foundations.
The main objective of the present project is to verify the interaction between the foundation structure of a machine - an industrial fan - with the excitation source, its own motor, in this case to identify possible occurrence of the so called "jump phenomenon", also known as Sommerfeld Effect. Such phenomenon is derived from the dynamic coupling between the

12. MODELAGEM E PREVISÃO DO COMPORTAMENTO DE PREÇOS DA COMMODITY CAFÉ ARÁBICA: UMA ABORDAGEM PELA METODOLOGIA DE SANJIV DAS / MODELING AND FORECASTING THE BEHAVIOUR OF ARABIC COFFEE COMMODITYS PRICES: AN APPROACH BY THE METHODOLOGY OF SANJIV DAS
The agribusiness has great importance for the Brazilian economy, representing a significative share of GDP and total exports of the country. Like other production processes inserted in an environment of uncertainty, the agricultural activity needs instruments that minimize the risk, especially, the risk of price and assist in decision-making process of agent
