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. Avaliação de Parametrizações de Camada Limite Planetária do Modelo WRF na Costa Norte do Nordeste do Brasil
Resumo Este trabalho tem como objetivo avaliar duas simulações do modelo WRF que diferem em sua parametrização da Camada Limite Planetária (CLP). Foram utilizados dados de 72 radiossondas lançadas em Fortaleza (CE) entre 5 e 25 de Abril de 2011 nos horários sinóticos. A altura da CLP foi a variável avaliada e os valores observados, calculados pelo m

3. Importância da obtenção do plano oclusal com arco facial para planejamento do avanço maxilar em cirurgias ortognáticas bimaxilares / Influence of wrong determination of occlusal plane in maxillary advancement : a model surgery study
This study investigated whether an occlusal plane error of acquisition can influence in the treatment planning and result of maxillary advancement in double-jaw surgeries. Advancement of 8 and 4 millimeters were studied in different groups. For each group 20 maxillary models were mounted by a 13 degrees platform with superior articulator arm (control group)

5. Horizontal and vertical positional accuracy assement of cartographic products of the amazon region derived from interferometric sar data in X and P bands from ORBISAR sensor / Avaliação da acurácia posicional planialtimétrica de produtos cartográficos da Região Amazônica extraídos de dados SAR interferométricos nas bandas X e P do sensor ORBISAR
The Geographic Service of the Brazilian Army (DSG) is running a major mapping project in Brazil, called ´´Radiography Amazon", the region known as ´´Empty Mapping the Amazon." This area, approximately 1,8 million km$^2$, has not had, to date, appropriate land information mapping at scales larger than 1:250,000, except insufficient cartographic documents

6. Postural assessment software (PAS/SAPO): validation and reliabiliy
OBJECTIVE: This study was designed to estimate the accuracy of the postural assessment software (PAS/SAPO) for measurement of corporal angles and distances as well as the inter- and intra-rater reliabilities. INTRODUCTION: Postural assessment software was developed as a subsidiary tool for postural assessment. It is easy to use and available in the public do

7. Vestibular function evaluation by subjective visual vertical in patients with Parkinsons disease / Avaliação da função vestibular através da vertical visual subjetiva em pacientes com doença de Parkinson
Introduction: Postural instability is a late manifestation of Parkinsons disease (PD). The impairment of postural responses on PD is probably the most important cause of falls. These postural responses depend on vestibular, somatossensorial and visual inputs, and they are integrated on basal ganglia, brainstem and spinal cord. By use of the subjective visual

8. Avaliação da morfologia craniofaciall de indivíduos com deformidades dentofaciais de classe III por meio de tomografias computadorizadas de feixe cônico / Evaluation of the craniofacial morphology of subjects with dentofacial Class III deformities using cone beam computed tomography
Class III dentofacial deformity is associated with important functional, psychologic and aesthetics changes. The objective of this study was to evaluate the craniofacial morphology of adults, with Class III dentofacial deformity comparing them with a group of subjects with harmonious faces for diagnosis and prognosis in orthodontic and surgical cases. This s

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

10. Influence of the distance of installation of tensiometers to calculate total potential gradient in the field soil hydraulic conductivity determination / Influência da distância de instalação de tensiômetros no campo para o cálculo do gradiente de potencial total no método do perfil instantâneo
The soil hydraulic conductivity determination method most used under unsaturated field conditions is the instantaneous profile method. This method is based on the integration of Richards equation in relation to soil depth, during the soil water redistribution process, after the profile has been saturated till the interest depth and the soil surface prevented

11. Estrutura, estratificação e grupos ecológicos de um fragmento de floresta estacional semidecidual (Uberaba, MG)
Seasonal semideciduous forests (FES) occur in patches mainly in the region of the Cerrado of central Brazil, had occupied a expressive area throughout Minas Gerais state. These formations generally occur on fertile and humid soil, characterized for the climatic changes that determines the seasonal deciduousness of the dominant tree individuals, in reply the
