1. A Novel In Silico Monte Carlo Approach to Optimize a PSD Estimation Problem. Generation of Data Fusion Experiment Rules
ABSTRACT This article analyzes the performance of combining information from Scanning Electron Microscopy (SEM) micrographs with Static Light Scattering (SLS) measurements for retrieving the so-called Particle Size Distribution (PSD) in terms of experimental features. The corresponding data fusion is implemented using a novel Monte Carlo-based method consist

3. Data processing within rows for sugarcane yield mapping
ABSTRACT: The mapping of sugarcane yield is still not as widely available as it is for grain crops. Sugarcane harvesters cut and process the cane in a single or maximum of two rows, facilitating the monitoring of cane yield and its behavior on a small scale. This study tested a method for sugarcane yield data cleaning, investigating if the data recording fre

4. DESHADOWING OF HIGH SPATIAL RESOLUTION IMAGERY APPLIED TO URBAN AREA DETECTION
Abstract Different built-up structures usually lead to large regions covered by shadows, causing partial or total loss of information present in urban environments. In order to mitigate the presence of shadows while improving the urban target discrimination in multispectral images, this paper proposes an automated methodology for both detection and recovery

6. Classification of Flying Insects with high performance using improved DTW algorithm based on hidden Markov model
ABSTRACT Insects play significant role in the human life. And insects pollinate major food crops consumed in the world. Insect pests consume and destroy major crops in the world. Hence to have control over the disease and pests, researches are going on in the area of entomology using chemical, biological and mechanical approaches. The data relevant to the fl

8. Filtragem robusta recursiva para sistemas lineares a tempo discreto com parâmetros sujeitos a saltos Markovianos / Recursive robust filtering for discrete-time Markovian jump linear systems
Este trabalho trata de filtragem robusta para sistemas lineares sujeitos a saltos Markovianos discretos no tempo. Serão desenvolvidas estimativas preditoras e filtradas baseadas em algoritmos recursivos que são úteis para aplicações em tempo real. Serão desenvolvidas duas classes de filtros robustos, uma baseada em uma estratégia do tipo H \ INFINITO\

9. Multiple causes of death related to alcohol consumption in the micro region of Ribeirão Preto - SP, 1996 - 2007 / Causas múltiplas de morte relacionadas ao consumo de álcool na microrregião de Ribeirão Preto - SP, 1996 - 2007
There are great number of evidences the allow to characterize the role of alcohol as a risk factor for diseases and death, besides several negative social consequences. Thus, consumption of alcoholic beverages has become a worldwide concern, being hailed as a major public health problem. Considering the limitations of health statistics that take into conside

10. Estimação de estado em sistemas elétricos de potência: composição de erros de medidas / State estimation in power systems: measurement error composition
Bretas et al. (2009) has proved, using geometric background, that the measurement error can be decomposed into two components the detectable and the undetectable component respectively. Bretas has also demonstrated that the current methodologies used for processing of gross errors (GE), consider only the detectable component of the error. Thus, depending on

11. Uma avaliação sobre características espaço-temporais baseadas em invariantes de cor para reconhecimento de ações
Local spatiotemporal feature has been proved to be a powerful tool to represent latent patterns of moving objects in video scenes. In particular, recognition of human actions has been the principal focus for various growing applications, including video indexing, content-based video retrieval, video summarization, filtering of unwanted content, rating of mov

12. Análise quantitativa da ocorrência de imagens de produtos na bibliografia de design para verificação de fidedignidade do conjunto destas imagens como representação do campo de atividade do design de produto / A quantitative analysis of design products images apearing in design literature, verifiyng if they constitute the true picture of the field of product design
Since, presently, there is no consensus with regard to various definitions of the concepts of \"design\" and \"product design\", the boundaries of the product designers\ field are perceived and shaped, to a great extent, by visual examples supplied by books, magazines and newspapers that are accessible to the general public, as well as to students, designers
