Interface para classificação de dados por máquinas de vetores de suporte

In this project the Pattern Recognition Problem is approached with the Support Vector Machines (SVM) technique, a binary method of classification that provides the best solution separating the data in the better way with a hiperplan and an extension of the input space dimension, as a Machine Learning solution. The system aims to classify two classes of pixels chosen by the user in the interface in the interest selection phase and in the background selection phase, generating all the data to be used in the LibSVM library, a library that implements the SVM, illustrating the library operation in a casual way. The data provided by the interface is organized in three types, RGB (Red, Green and Blue color system), texture (calculated) or RGB + texture. At last the project showed successful results, where the classification of the image pixels was showed as been from one of the two classes, from the interest selection area or from the background selection area. The simplest user view of results classification is the RGB type of data arrange, because it’s the most concrete way of data acquisition

Classificação e quantificação de tecidos Biológicos para construção de fantomas pediátricos

Paediatric diagnostic radiology can be considered as a separate specialty and with distinct characteristics of the radiology applied in adult patients. This in reason of the variability in the anatomical structures size and bigger sensitivity of tissues. The literature present in its majority methodologies for segmentation and tissue classification in adult patients, and works on tissue quantification are rare. This work had for objective the development of a biological tissue classifier and quantifier algorithm, from histograms, and that converts the quantified average thickness of these tissues for its respective simulator materials. The results will be used in the optimization process of paediatrics images, in future works, since these patients are frequently over exposed to the radiation in the repeated attempts of if getting considered good quality radiographic images. The developed algorithm was capable to read and store the name of all the archives, in the operational system, to filter artifacs, to count and quantify each biological tissues from the histogram of the examination, to obtain the biological tissues average thicknesses and to convert this value into its respective simulator material. The results show that it is possible to distinguish bone, soft, fat and pulmonary tissues from histograms of tomographic examinations of thorax. The quantification of the constituent materials of anthropomorphic phantom made by the algorithm, compared with the data of literature shows that the biggest difference was of 21,6% for bone. However, the literature shows that variations of up to 30% in bone thickness do not influence of significant form in the radiographic image quality. The average thicknesses of biological tissues, quantified for paediatrics patients, show that one phantom can simulate patients with distinct DAP ranges, since variations...

Classificação do grupo sucessional de espécies nativas por análise do processo de estiolamento de plântulas

As plantas apresentam moléculas que detectam a luz, entre elas estão os fitocromos que detectam mudanças na qualidade da luz nas regiões de vermelho (V) e vermelho-extremo (VE). O fitocromo age no crescimento das plantas possibilitando-as perceber o sombreamento por outras plantas, o que pode ocasionar no processo de estiolamento, ou seja, alongamento do caule. Assim, conforme aumenta o sombreamento, a razão V:VE diminui. Nas plantas de sol, quanto maior a proporção de VE, maior a taxa de estiolamento, enquanto que as plantas de sombra mostram pouca ou nenhuma redução na taxa de alongamento dos caules. Na sucessão florestal as plantas podem ser classificadas como pioneiras, sendo aquelas dependentes de luz e intolerantes à sombra, e as de transição ou clímax, que são tolerantes à sombra. Assim, este trabalho teve o intuito de analisar o processo de estiolamento de plântulas de espécies arbóreas nativas selecionadas, mantidas em condições de luz diferentes e correlacionar com a classe seral correspondente citada na literatura. As seguintes espécies foram analisadas: Bixa orellana, Caesalpinia peltophoroides, Dalbergia nigra, Erythrina speciosa, Eugenia uniflora, Hevea brasiliensis, Hymenaea courbaril, Licania tomentosa, Pachira aquatica, Piptadenia gonoacantha, Psidium guajava, Schizolobium parahyba. Todos os experimentos foram desenvolvidos no jardim experimental da UNESP de Rio Claro. As espécies foram expostas a seis condições luminosas diferentes, com razão V:VE de: 0,1; 0,19; 0,21; 0,35; 1,15 e 1,17. E radiação solar incidente de: 3,16UM; 44,78UM; 27,7UM; 73,54UM; 1987,00UM; 1453,00UM. Foram tiradas medidas do comprimento dos hipocótilos e epicótilos. Posteriormente foram realizadas análises estatísticas com nível de significância de 5%. As espécies consideradas pioneiras foram D. nigra e S. parahyba. E as espécies classificadas como não pioneiras foram:... (Resumo completo, clicar acesso eletrônico abaixo)

Green and brown propolis: efficient natural biocides for the control of bacterial contamination of alcoholic fermentation of distilled beverage

This study aimed to evaluate the efficiency of natural biocides, brown and green propolis, for the control of bacterial contamination in the production of sugarcane spirit. The treatments consisted of brown and green propolis extracts, ampicillin, and a control and were assessed at the beginning and end of harvest season in ten fermentation cycles. In the microbiological analyses, the lactic acid bacteria were quantified in the inoculum before and after the treatment with biocides, and the viability of yeast cells during fermentation was evaluated. The levels of acids, glycerol, total residual reducing sugars, and ethanol were analyzed for the wine resulting from each fermentation cycle. A reduction in the number of bacterial contaminants in the inoculum in the treatments with the natural biocides was observed, but it did not affect the viability of yeast cells. The control of the contaminants led to the production of higher levels of ethanol and reduced acidity in the wine produced. The results of the use of brown and green propolis to control the growth microorganisms in the fermentation of sugarcane spirit can be of great importance for using alternative strategies to synthetic antibacterials in fermentation processes including other distilled beverage or spirits.
