1. SPATIAL OUTLIERS DETECTION ALGORITHM (SODA) APPLIED TO MULTIBEAM BATHYMETRIC DATA PROCESSING
Abstract: The amount of data produced in an echosounder has increased dramatically with scanning systems such as multibeam echo sounders and interferometric sonars, providing a considerable improvement in the submerged terrain representation, especially when it comes to detecting hazardous objects to the navigator. However, the available processing algorithm

2. Spatial and temporal distribution of Gymnorhamphichthys rondoni (Gymnotiformes: Rhamphichthyidae) in a long-term study of an Amazonian terra firme stream, Leticia - Colombia
ABSTRACT Weakly electric fishes continually emit electric organ discharges (EOD) as a means of communication and localization of objects in their surroundings. Depending on water conductivity, the amplitude of the electric field generated is known to increase with decreases in electrical conductivity of the water. In Amazonian terra firme streams, water cond

3. ROBUST METHODOLOGY FOR DETECTION OF SPIKES IN MULTIBEAM ECHO SOUNDER DATA
Abstract Currently, during the operation in shallow waters, scanning systems, such as multibeam systems, are capable of collecting thousands of points in a short time, promoting a greater coverage of the submerged bottom, with consequent increase in the detection capacity of objects. Although there has been an improvement in the accuracy of the depths collec

4. Multitemporal variables for the mapping of coffee cultivation areas
Resumo: O objetivo deste trabalho foi propor uma nova metodologia para o mapeamento de áreas cafeeiras que inclui dados multitemporais como parâmetros de entrada no processo de classificação, por meio de uma série temporal NDVI do Landsat TM, juntamente com uma abordagem de classificação orientada a objeto. O algoritmo BFAST foi utilizado para a anál

5. Procesos de Visualización en una Tarea de Generación y Representación de Cuerpos de Revolución
Abstract In this work we analyzed the visualization processes involved in a mathematical task that requires generating and representing solids of revolution. The task was administered to four hundred university students from the Bachelor's Degree in Primary Education. We adopted the Ontosemiotic Approach to Mathematical Instruction and Knowledge as a theoret

6. Validation of the Mnemonic Similarity Task – Context Version
Objective: Pattern separation (PS) is the ability to represent similar experiences as separate, non-overlapping representations. It is usually assessed via the Mnemonic Similarity Task – Object Version (MST-O) which, however, assesses PS performance without taking behavioral context discrimination into account, since it is based on pictures of everyday si

7. Dynamic Digital Holography for recording and reconstruction of 3D images using optoelectronic devices
Abstract In this work, we present the optical recording and reconstruction of dynamic 3D digital holograms using optoelectronic devices. Digital Holography technique allows recording and reconstruction of three-dimensional images of real objects, since a hologram presents both the intensity and phase information about the object. The experimental implementat

8. COMPARATIVE ASSESSMENT BETWEEN PER-PIXEL AND OBJECT-ORIENTED FOR MAPPING LAND COVER AND USE
ABSTRACT: The traditional per-pixel classification methods consider only spectral information, and may be limited. Object-based classifiers, however, also consider shape and texture, firstly segmenting the image, and then classifying individual objects. Thus, a Geographic Object-Based Image Analysis (GEOBIA) was compared in conjunction with data mining techn

9. Modernizações seletivas e os circuitos espaciais da economia urbana: cidades e prisões no atual período tecnológico
In the current technical-scientific-informational period, the relations between the territory of the cities and prisons are quite complex. They are constituted from different spatial circuits, beyond the contiguous boundaries of the immediate surroundings of prisons. As control and punishment tools, currently, prisons are central objects in various uses, pra

10. Caracterização da somestesia tátil em crianças com hemiparesia: comparação de três métodos de avaliação / Characterization of tactile somesthesia in children with hemiparesis: comparison of three methods of assessment
The analysis of sensorimotor integration in children with hemiparesis is necessary for choosing of efficient therapeutic strategies to functionality recovery. The objectives of this study were: i) to compare three instruments of tactile sensibility assessment; ii) to describe the alterations of tactile sensibility in children with hemiparesis. The Study Grou

11. Razonamiento geométrico y visualización espacial desde el punto de vista ontosemiótico
As part of an investigation on the evaluation and development of visualization skills and spatial reasoning, we present the analysis of a task used with a sample of 400 student teachers. The analysis is carried out applying the notion of configuration of objects and processes introduced in the "onto-semiotic approach" to mathematical knowledge and instructio

12. Raciocínio sobre conhecimento visual : um estudo em estratigrafia sedimentar / Reasoning over visual knowledge: a study in sedimentary stratigraphy
Imagistic domains are those in which problem-solving process begins with the recognition of domain objects trough the visual information captured, supporting more abstract interpretations in subsequent steps. The problem-solving process, in imagistic domains, is performed trough intensive application of visual knowledge, which corresponds to the set of menta
