Estudo e simulação de redes de sensores em superfícies não-planas

This Bachelor’s Thesis of Bachelor of Computer Science defines a research and a network sensor simulation on non-planar surfaces . The report is composed of an introduction of the research, a theoretic study, a state of the art and a historic context of sensor network. The simulation consists of the formation of terrain, node’s random distribution and a production and a transmission of the node’s packages. Based on these three important topics , the exchange of information/packages between multiple nodes is through breadth-first search algorithm. The active nodes, node quantity and operation range are also defined in the program. After the program analysis the node activation, the packages are created and transmitted to the next node. This process occurs many times and help on the analysis of the sensor network on non-planar surfaces parameters

Métodos diagnósticos para detecção da Leucemia viral felina

The feline leukemia virus (FeLV) was described in 1964 by William Jarrett and collaborators wen find viral particles attached to the membrane of lymphoblasts in cat with lymphoma. The virus belongs to the family Retroviridae, subfamily oncornavirus. With worldwide distribution, the occurrence of FeLV has 1.6% in healthy cats and 10.8% in sick cats in Brazil. The mortality of persistently viremic animals in catteries is about 50% in two years and 80% in three years. In catteries that have endemic feline Coronavirus (FCoV), FeLV and / or Feline Immunodeficiency Virus (FIV), the FeLV infection has greater contribution to mortality. The test for infection and FeLV positive cats segregation is the main way to prevent the spread of infection. The diagnostic methods are based on clinical signs and changes compatible with FeLV infection observed by physical examination, complete blood count, X-ray, bone marrow aspirate and biochemical. The viral p27 protein is produced in infected cells in high amounts and is found in abundance in the cytoplasm and in body fluids enabling diagnosed methods such as enzyme-linked immunosorbent assay - ELISA and direct immunofluorescence, detection of viral genome (Chain Reaction Polymerase - PCR) and detection of the virus by virus isolation. Although diagnostic tests are highly sensitive, it should be made more than a confirmatory test, especially serological due to variable characteristic of the progress of infection

Caracterização da demanda do pronto socorro do Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP

The demand for health services can be understood as an application needs the user has. The inability to use the outpatient services and limited supply of these make it possible for users to browse sites that focus attention on a greater possibility of entry doors, in which first-aid centers and hospital emergency match this profile, distorting the flow of patients in the network through an inverse demand of the movement hierarchy. Added to this, the burden of care in these services results in overcrowding and poor quality of care. Evaluate the demand of the visits occurred in the Emergency Room of the Hospital of the Medical School of Botucatu / UNESP (PS - HC - FMB / UNESP) during June-July 2010. A transversal, descriptive and retrospective. For data collection sheet was used in the proposed Service unit and the data it was filled out the form with the necessary items for the search. Made an exploratory analysis and frequency distributions for categorical variables of the form. Females predominated (56%) and aged 61 years or older with 30%. 96.5% were owned by DRS VI, and 62.5% of Botucatu. The attendance by the physician on duty and corresponded to 57.7% among the 23 medical specialties, Gastric (7.0%), Cardiology (4.5%), Medical (4.4%), urology (4.2%) and Pulmonology (4.1%) were the ones that stood out. The medical procedures performed that stood out were X-ray (46.4%) and electrocardiogram (ECG) (42.3%) and in most specialty care occurred, only the daily consultation with the patient. It was possible to characterize, so the demand for PS - HC - FMB / UNESP for the period June- July 2010, The predominance of the elderly shows that come along with aging diseases and addictions, causing a greater need for health services. Moreover, this study showed that the high number of visits is related to both the daily demands that the tertiary hospital has the same transformation...

Ótica e a visão humana

Optics consists in the study of interaction of light with physical systems. The human vision is a product of the interaction of light with the eye (a very peculiar physical system). Here we present a basic study of the relationship between the optics and human vision, including: - The fundaments and physicals properties who characterize the light and the colors and the characteristics of the incidence mediums. - The basics laws of geometrical optics, based in the rectilinear propagation of light in the form of a light ray, in the independence of light rays and in the principle of reversibility of the light beams. This principle is present in the process of image formations in lenses and mirrors and applied in the study of image formation in the human eye. - The refraction and reflection laws and types of lenses, who permits the construction of optics devices for the study of physical universe, and the appliances to correct vision diseases. - Presents the human vision process as consisting in the reception of light (electromagnetic radiation in the zone of wavelength visible to us) through the eye and the sending of information obtained by the retina to the brain where it is interpreted. The vision involves a biophysical relation between the light and the biological structure of the eye who is constituted by cornea, iris, crystalline and retina. Analyzes is made of how some parts of the eye performs a function in the reception and sending of information of the images to the brain

Atmospheric Discharges are responsible for several lost in the electrical system therefore it´s done studies to find ways to reduce the problem caused by discharges. This branch of engineering is necessary the gathering, stock and analysis of large quantity of data to validate or refuse the many studies produced about it The CENDAT proposed a project to collect data on induced voltages in distribution lines and current waveform of the lightning, but a difficulty that arose was the accumulation of data due to lack of manpower available to catalog all the data collected. Thinking in this difficulty, the engineer Acacio Silva Neto CENDAT´s researcher with trainees began to develop a program to solve this problem. This work keeps the development of this program in order to solve the problem of accumulation of data

Caracterização e origem da composição química da incrustação e simulação de cenários de perda de energia em setor da rede de abastecimento de água da cidade de Rio Claro - SP

The purpose of this work was the inlay’s characterization from the water supply networks of Rio Claro-SP city; as well analyze the influence of network’s aging in the actual system. To do this, some samples of inlays were collected and made chemistry analysis and X-Ray Diffraction Spectrometry. The history of the source water quality was also analyzed, to make possible to known the origins of the inlays. To evaluate the performance of the network, some different scenarios have been simulated, varying the resistance coefficient of the water supply networks of Rio Claro-SP. The characterization results showed that there are basically oxide and hydroxide of iron (magnetite and goethite) and quartz in the inlays, which are materials of high hardness. The hydraulic simulations indicated that the simulated scenarios had a variation of ~2000% in terms of loss of energy

Aplicações clássicas da técnica de espalhamento de raios-x a baixo ângulo em materiais nanoestruturados

The small angle X-ray scattering (SAXS) technique has been used with very much versatility and success in the structural characterization of nanostructured materials. The present work deals with a study of the principles of the SAXS technique and of some classical models employed in the structural characterization of nanostructured materials. Particularly, the study of the models and of the associated methodologies is applied to a set of samples of silica gels, of varied typical structures, prepared in the Laboratório de Novos Materiais of the Departamento de Física of the IGCE. The work discusses in an introductory chapter the principles of the SAXS technique and the foundation of classical models often used in the structural characterization of materials. The classical models and the associated methodologies were applied to a variety of silica gel structures. The studies include: i) the scattering from a system of particles - Guinier's law; ii) the asymptotic scattering from a two-phase system - Porod's law; iii) systematic deviation from Porod's law - Surface Fractal; iv) heterogeneities in solids with random size distribution - DAB Model; and v) the scattering from mass fractal structures. The analyses were carried out from experimental SAXS data obtained in several opportunities at the Laboratório Nacional de Luz Síncrotron (LNLS)

Estudo do efeito das mudanças no uso do solo nas adjacências de uma reserva de cerrado sobre sua fauna apícola

Insetos e outros invertebrados desempenham papel chave nos ecossistemas terrestres por estarem envolvidos com processos de decomposição, ciclagem de nutrientes, polinização, dispersão e predação de sementes, etc. A fragmentação de habitats reduz sua área original, podendo causar extinções locais, alteração na composição e abundância de espécies e levar à perda de processos naturais das comunidades. Além disso, modifica os padrões de distribuição dos organismos, leva a uma redução da fonte de recursos disponíveis, interfere na dinâmica metapopulacional e gera efeitos negativos na abundância e diversidade genética, que pode contribuir para o declínio de muitas espécies. Neste estudo foram identificadas as mudanças de uso e ocupação dos solos ocorridas nos últimos 35 anos no entorno da Reserva de Cerrado de Corumbataí e sua influência sobre sua fauna de abelhas, tendo como referência levantamentos de espécies realizados nos anos de 1982, 1983 e 1984 e em seguida nos anos de 2000 e 2001. As espécies de abelha foram separadas por guildas de polinização para refletir melhor sua diversidade funcional na área de estudo. A vegetação visitada por estas abelhas foi separada de acordo com o bioma ao qual pertence e elaborou-se mapas temáticos de uso e cobertura do solo dos anos de 1975, 1981 e 2010 a partir de geoprocessamento no Spring 5.0 e criação de um Plano de Informação contendo a máscara de 10 Km de raio no entorno do fragmento a partir de imagens de composição colorida das bandas 4, 2, 3 (RGB) do LANDSAT 5, resolução de 30 m e LANDSAT 1 e 2 com resolução de 60 m disponibilizadas pelo Instituto Nacional de Pesquisas Espaciais (INPE).

Modelagem matemática para a dispersão de fungos fitopatogênicos via autômatos celulares

Brazil is a major world producer and exporter of agricultural products like soybeans, sugar, coffee, orange and tobacoo. However, the action of phytopathogenic fungi has been one of the largest challenges encountered in the field as they are responsible for approximately 25 to 50 per cent of losses in crops of fruits and vegetables. The presence of these pathogens is always a problem, because the damage on the tissues and organs promote lesions which decreses growth vegetation and often leads the individual (host) to death. Therefore, it is crucial to understand the process of spreading of these pathogens in the field to develop strategies which prevent the epidemics caused by them. In this study, the dispersal of fungi phytopathogenic in the field was modeled using the automata cellular formalism. The growth rate of infected plants population was measured by the radius of gyration and the influence of host different susceptibility degrees into the disease spread was assessed. The spatial anisotropy related to the plant-to-plant space and the system’s response to distinct seasonal patterns were also evaluated. The results obtained by a mean field model (spatially implicit models) emphasized the importance of the spatial structure on the spreading process, and dispersal patterns obtained by simulation (using a cellular automata) were in agreement with thse observed in data. All computational implementation was held in language Cl

Uso do ATP para simulações de descargas atmosféricas em para-raios de 15 kV dos serviços auxiliares de subestações de energia elétrica

This paper addresses the topics required for the selection of surge arresters used, the output of autotransformers, which protect the system Auxiliary Services (SE) of an electrical substation. Surge arresters used are part of the Protection System Lightning (SPDA). Transmission lines mostly run through regions with orographic well diversified and have constant weather changes, which lead to many undesirable interactions with electromagnetic phenomena, such as giving rise to blackout on 10 November 2009, which left nine states without power, which led to unplanned shutdowns in the system that left millions of people without electricity. This work of completion is to determine whether the method used in the selection of surge arresters meet the protection needs faced by a substation auxiliary services, through the use of software use ATPDraw
