A NEURAL NET FOR EXTRACTING KNOWLEDGE FROM NATURAL-LANGUAGE DATA-BASES

The present paper introduces a new model of fuzzy neuron, one which increases the computational power of the artificial neuron, turning it also into a symbolic processing device. This model proposes the synapsis to be symbolically and numerically defined, by means of the assignment of tokens to the presynaptic and postsynaptic neurons. The matching or concatenation compatibility between these tokens is used to decided about the possible connections among neurons of a given net. The strength of the compatible synapsis is made dependent on the amount of the available presynaptic and post synaptic tokens. The symbolic and numeric processing capacity of the new fuzzy neuron is used here to build a neural net (JARGON) to disclose the existing knowledge in natural language data bases such as medical files, set of interviews, and reports about engineering operations.

Características produtivas e morfológicas do capim Tanzânia em diferentes intensidades de pastejo

The objective of this study was to determine the best height of the Tanzania grass under grazing, assessing morphological and productive characteristics of the sward. This experiment was conducted in Cidade Gaucha, Parana, where he was rated the accumulation rate and morphological characteristics of Tanzania grass pastures grazed at 20, 40, 60 and 80 cm grazing under continuous stocking with variable stocking rate for beef cattle. The experimental area was 12 hectare divided in paddocks of one hectare each. For each paddock were allocated two grazing exclusion cage for estimating herbage accumulation, and eight samples were taken every 28 days throughout the year 2010. The completely randomized design. The herbage mass of the morphological structures showed a linear positive function of sward heights. The height of defoliation did not influence the rate of herbage accumulation for any of the morphological structures: green leaf, stem + sheaths and senescent material. There were also no differences in leaf: stem ratio. All heights within the range studied provided adequate number of green leaves per tiller. Tanzania grass pastures grazed under continuous stocking between 40 and 60 cm, for providing a good association between accumulation and mass of green leaf blades, and acceptable values of the mass of stem + sheaths and senescent material. Pasture of Tanzania grass under 60 and 80 cm allow of leaves satisfactory accumulation in the autumn.

Morbidades e consumo de álcool em pacientes internados na Clínica Médica de um hospital universitário

Abusive consumption of alcohol leads to several negative consequences to health and quality of life, as it increases the frequency of diseases that cause death or functional disabilities. The rates of patients admitted to hospital due to physical problems stemming from alcohol abuse are high. This study aimed at identifying patients according to variables age, gender and education level as well as at evaluating the prevalence of CAGE-positive patients and morbidity due to CID-10 (International Classification of Diseases) by the World Health Organization. It is a cross-sectional, observational, exploratory, descriptive and quantitative study. It was conducted at the Botucatu School of Medicine University Hospital (HC) from July to September 2010, at the Internal Medicine ward. This ward aggregates 5 specialties, namely, Cardiology, Hematology, General Medicine, Nephrology and Gastroclinic. Presently, it has 36 beds, of which four are for Intensive Care Therapy (ICT). Three hundred and ten medical charts were analyzed for identification of morbidities and of variables age, gender and schooling. A closed semistructured questionnaire including, among other questions, the CAGE test was applied to each individual. The CAGE test is a questionnaire that comprises four questions and considers that one who answers two or more of such questions affirmatively is a suspected case of alcoholism. The total population studied included 310 patients. Indexes of 60% (186) male and of 40% (124) female patients were found. As regards age range, a population with a higher prevalence of individuals from 51 to 70 years old (41%) was observed. The main education indexes were: incomplete Elementary School: 23.22% (72), complete Elementary School: 21.61% (67), incomplete Secondary School: 18.40% (57) and Illiteracy: 17.74% (55). As regards diseases, a higher proportion was observed for: ...(Complete abstract click electronic access below)

Comportamento de oviposição em Chrysomya megacephala (F.) (Diptera: Calliphoridae): distinção quantitativa frente a posturas prévias?

Chrysomya megacephala (Fabricius), has considerable medical, veterinary and forensic importance. In insects in general, the ability to track the food substrate is due to highly sensitive organs adapted for detecting odors, particularly in the case of blowflies, which is one of carcass main consumers. Eggs of blowflies are usually aggregated in function of the behavior of other pheromone mediated by females laying eggs in place on the same substrate. One of the main reasons for studying oviposition behavior is because it may indirectly affect individual qualification, population dynamics and community structure. It has been suggested that female blowflies can evaluate the number of eggs on a substrate, decreasing the size of oviposition in very saturated substrates with larvae or eggs leading to a lower intraspecific competition. The present study investigated the oviposition behavior of females of C. megacephala, and wished to consider whether they are able to distinguish quantitatively (size of the mass) eggs previously put into a place of posture and hence indicate whether there is a limit beneficial (to avoid competition among larvae) for its oviposition on the same substrate or if that place would already be saturated, requiring find another substrate without eggs or less for futures ovipositions. With 20 females and five males, five treatments were applied, repeated ten times and analyzed using the Mann-Whitney test. Each treatment consists in placing, inside the cage, a flask with 50g of ground beef and another one in the other side, with the same amount of substrate with a certain amount of prior oviposition for a period of 5 hours. The masses prior eggs were used 0.03 g, 0.05 g, 0.1 g, 0.2 g and 0.3 g (respectively, T1, T2, T3, T4 and T5). The other part of the work consisted in the use of a “Y” olfactometer, a device used to determine the choice of an invertebrate against... (Complete abstract click electronic access below)

Optimizing urban traffic flow using genetic algorithm with petri net analysis as fitness function

This paper describes a new methodology adopted for urban traffic stream optimization. By using Petri net analysis as fitness function of a Genetic Algorithm, an entire urban road network is controlled in real time. With the advent of new technologies that have been published, particularly focusing on communications among vehicles and roads infrastructures, we consider that vehicles can provide their positions and their destinations to a central server so that it is able to calculate the best route for one of them. Our tests concentrate on comparisons between the proposed approach and other algorithms that are currently used for the same purpose, being possible to conclude that our algorithm optimizes traffic in a relevant manner.

Avaliação dos componentes de óleos essenciais 1,8-cineol, β-cariofileno e α-humuleno como possíveis repelentes para Aedes (Stegomyia) aegypti (Diptera: Culicidae)

Aedes aegypti, mosquito da família Culicidae responsável pela transmissão dos vírus da dengue, da febre amarela urbana e da febre chikungunya, apresenta grande proliferação em áreas urbanas das regiões tropicais e subtropicais, além de representar um fator de incômodo por causar alergias devido à inoculação dos componentes salivares durante o processo do repasto sanguíneo. Como forma de evitar os problemas causados por eles, o repelente mais usado e registrado comercialmente desde 1957 é o DEET (N,N-dietil-3-metilbenzamida ou N,N-dietil-meta-toluamida), que apesar de apresentar eficácia comprovada possui determinada toxicidade quando utilizado por crianças e por mulheres grávidas ou lactantes. Atualmente, grande parte dos estudos sobre novas substâncias repelentes envolvem óleos essenciais de plantas, principalmente por serem atóxicos, biodegradáveis, possuírem um preço mais acessível e uma ampla atividade contra diferentes espécies de mosquitos. Os terpenos 1,8-cineol, β-cariofileno e α-humuleno podem ser encontrados em óleos essenciais de uma grande variedade de plantas e apesar de dados da literatura mostrarem uma eficácia dessas substâncias como repelentes para outras espécies de insetos, até o presente momento não existem estudos que relacionam porcentagem de repelência ao longo do tempo para avaliar o potencial de repelência das mesmas para culicídeos.O presente estudo avaliou tais substâncias como possíveis repelentes para A. aegypti, utilizando o DEET como controle positivo. Para avaliar a eficácia do β-cariofileno foi utilizada a BG-cage, uma gaiola desenvolvida especificamente para testes de repelência onde o voluntário expõe um braço sob uma abertura coberta por uma tela onde os mosquitos pousam, mas não picam. Os testes foram repetidos a cada 30 minutos após a aplicação do produto por um tempo máximo de duas horas (seguindo a recomendação de reaplicação do produto comercial ...

Um piloto de tradução alinhada e anotação em árvore sintática de dependência do grego antigo (AGDT 1.0) pela plataforma Alpheios.net com passagens de Heródoto

This study was developed based on Classical Greek Language classes, reading and translation of texts. There is also the presence of computer elements due to use of Alpheios digital platform. As an example of a larger proposal, this proposal aims at produce translation aligned with the Portuguese and syntactic annotation with the production of the Greek dependency trees. To achieve the goal, we chose Chapter 34, Volume 1 of The Histories from Herodotus. The methods adopted contain a list and description of the instruments and the morphological categories from the guide (manual rules of syntax tree). The procedures adopted are the description of the alignment process and of syntactic annotation. As study results, we have the production line translation and the syntactic annotation of the excerpt 1.34. It was concluded that the study of this text is relevant, because the lexical density of Herodotus it's interesting at future researchers and students that will use the digital platform Alpheios
