2. DELINEATION OF HOMOGENEOUS ZONES BASED ON GEOSTATISTICAL MODELS ROBUST TO OUTLIERS
RESUMO Diversas pesquisas utilizam medidas de condutividade elétrica aparente do solo (CEa) como indicador da variabilidade espacial de atributos físico-químicos existentes no campo de produção. Com base nestas medidas, zonas de manejo (ZM) são delineadas para aperfeiçoamento da gestão agrícola. Entretanto, estas amostras têm apresentado presença

3. Mean scatterer space estimation from ultrasound signals combining singular spectral analysis and entropy
AbstractIntroduction: Ultrasound (US) is a nonionizing radiation capable of real time imaging at low cost. Its most attractive application is quantitative tissue characterization with the objective of differentiating normal tissues from diseased tissues. In this study, an automated method using singular spectrum analysis (SSA) to estimate the mean scatterer

4. Online hybrid modeling method with application for predicting Bauxite production indicators
Abstract In the bauxite flotation process, concentrate grade and tailings grade are key production indicators; however, they are difficult to measure online. It is also difficult to develop an effective mathematical model for the process because of the complex non-linear and uncertain relationship among the feed parameters (feed grade, pulp density, slurry p

5. Automatic pain quantification using autonomic parameters
The objective measurement of subjective, multi-dimensionally experienced pain is a problem for which there has not been an adequate solution. Although verbal methods (e.g., pain scales and questionnaires) are commonly used to measure clinical pain, they tend to lack objectivity, reliability, or validity when applied to mentally impaired individuals.

6. Epidemiologia dos subtipos de depressão: análise de classes latentes dos sintomas depressivos em uma amostra populacional da região Metropolitana de São Paulo / Epidemiology of subtypes of depression: latent class analysis of depressive symptoms in a population-based sample of São Paulo Metropolitan Area
Introduction. Depression is a heterogeneous clinical syndrome characterized by distinct symptom profiles. However, few studies have investigated depressive subtypes in the community and their sociodemographic and clinical correlates, differentiating them on the presentation according to gender. Methods. Data comes from the São Paulo Megacity Mental Health S

7. Information theory and adaptivity in the species distribution modeling. / Teoria da informação e adaptatividade na modelagem de distribuição de espécies.
Species distribution modeling is a technique the purpose of which is to estimate models based on ecological niche. These models can assist decision making processes, planning and carrying out actions aiming at environmental conservation and preservation. There are several tools designed for species distribution modeling, such as the open- Modeller framework,

8. A fault location method using Lamb waves and discrete wavelet transform
Non-destructive evaluation methods and signal process techniques are important steps in structural health monitoring systems to assess the structure integrity. This paper presents a method for fault location in aluminum beams based on time of flight of Lamb waves. The dynamic response signal captured from the structure was processed using the discrete wavele

9. Human thermal comfort: an irreversibility-based approach emulating empirical clothed-body correlations and the conceptual energy balance equation
Exergetic analysis can provide useful information as it enables the identification of irreversible phenomena bringing about entropy generation and, therefore, exergy losses (also referred to as irreversibilities). As far as human thermal comfort is concerned, irreversibilities can be evaluated based on parameters related to both the occupant and his surround

11. The concept of informacional entropy can predict sequence learning, in rats? / O conceito de entropia informacional permite prever a aprendizagem serial, em ratos?
Prediction of environmental events, relying on memories of past regularities, is one of the fundamental functions of complex nervous systems. Sequences of serially ordered stimuli allow extracting information that defines its serial pattern. These patterns allow prediction of the next item in a sequence of events, facultating previous preparation to deal wit

12. Entropia informacional e aprendizagem de sequências / Information entropy and sequence learning
Experiências armazenadas acerca de regularidades passadas permitem a previsão do ambiente e, consequentemente, a possibilidade de ações antecipadas. Esta capacidade cognitiva é expressa em modelos de aprendizagem de sequências, que são capazes de acessar a previsibilidade das sequências de eventos e gerar descrições do desempenho em protocolos expe
