MODELING A COMPUTER APPLICATION FOR MANAGEMENT OF MAINTENANCE ACTIVITIES OF UNPAVED ROADS

ABSTRACTThis study presents a contribution to the modeling of a computer application employing a method of serviceability performance for unpaved roads, aiming the management of maintenance/restoration activities of the primary surface layer. The proposed methodology consisted of field inspections during dry (April to September) and rainy (October to March) periods, during which objective evaluations were performed to survey of defects and their densities and degrees of severity. To aid the functional classification of analyzed road sections and the determination of the defect with major influence on the serviceability of these roads, the method of serviceability performance proposed by Silva (2009)was implemented in the Visual Basic for Applications (VBA) language in Microsoft Excel software. With the use of the computer application proposed it was possible to identify among the defects analyzed in field, through the index of serviceability of the sampling unit per defect type (ISUdef), which one had the greatest influence on determining the relative serviceability index per road section (IST). The results allow us to conclude that the computer application Road achieved satisfactory results, since the objective evaluation criteria applied to road sections denotes consistency regarding their serviceability.

Penetrômetro de impacto stolf - programa computacional de dados em EXCEL-VBA

Há dois principais tipos de penetrômetro, o estático e o dinâmico. No primeiro, uma haste com uma ponta cônica é introduzida contínua e lentamente (quase estático), registrando-se concomitantemente a força de reação que é igual à resistência do solo. No segundo, utiliza-se a mesma haste. Contudo, esta é introduzida por meio da promoção de uma massa de impacto em queda livre. Dessa forma, a teoria pode ser tratada pela dinâmica newtoniana para obtenção da resistência. O objetivo do programa é proporcionar uma ferramenta rápida, facilitadora da computação de dados de resistência do solo, para esse último penetrômetro, resultando tabelas e gráficos já no formato científico. Desenvolvido em linguagem de programação Visual Basic Aplication (VBA), escolheu-se o aplicativo Excel como interface com o usuário pela sua popularidade. É constituído por quatro planilhas, duasauxiliares, sendo duas delas essenciais, Plan1 e 2: Plan1 - dados de entrada (número de impactos e profundidade). Concomitante à digitação, a tabela de resistência é confeccionada com o respectivo gráfico, podendo tabelar 40 perfis. Plan2 - cumpre função especial de equalizar, ou seja, padronizar a profundidade em camadas constantes, permitindo unificar todos os perfis em uma única tabela. Para tal, escolhe-se uma espessura de camada (exemplo: 5 cm); em seguida, o programa coleta os dados de resistência (MPa) da Plan1 e interpola os valores para a profundidade de 5 em 5 cm. Após realizar esse procedimento para todas as tabelas da Plan1, o programa gera, na Plan2, uma única tabela com todos os perfis, a média geral e os respectivos gráficos. É possível selecionar os perfis; por exemplo, apenas os medidos na linha ou entrelinha de plantio e eliminar perfis a critério do usuário. Como objetivo complementar, descreve-se a evolução do projeto "Penetrômetro de impacto", iniciado em 1982, cuja técnica passou a ser adotada no meio científico, após a publicação da teoria nesta revista em 1991. Apresenta-se também levantamento no meio científico nos últimos três anos (2010-2012), propiciando uma visão das principais aplicações na atualidade.

Utilização de filtro de transformada de fourier para a minimização de ruídos em sinais analíticos

Instrumental data always present some noise. The analytical data information and instrumental noise generally has different frequencies. Thus is possible to remove the noise using a digital filter based on Fourier transform and inverse Fourier transform. This procedure enhance the signal/noise ratio and consecutively increase the detection limits on instrumental analysis. The basic principle of Fourier transform filter with modifications implemented to improve its performance is presented. A numerical example, as well as a real voltammetric example are showed to demonstrate the Fourier transform filter implementation. The programs to perform the Fourier transform filter, in Matlab and Visual Basic languages, are included as appendices

Determinação do perfil radial de aspersores a partir de ensaios de distribuição de água em sistemas autopropelidos de irrigação

Este trabalho apresenta uma rotina computacional, em Visual Basic 6, para determinar o perfil radial de aspersores, mediante ensaios de equipamentos autopropelidos de irrigação. Para a avaliação do programa, foi utilizado o aplicativo computacional SIMULASOFT e dados de ensaios de campo de sistemas autopropelidos de irrigação. As lâminas aplicadas, geradas pelo programa SIMULASOFT, foram para o aspersor PLONA-RL250 (bocal = 20 x 6 mm; pressão = 490 kPa), em deslocamento linear com velocidade de 50 m h-1, e quatro ângulos de giro distintos (180; 270; 330 e 360º). As lâminas aplicadas, observadas nos ensaios de campo, em condições de vento menores que 1,5 m s-1, foram para o aspersor PLONA-RL250, operando na pressão de 392 kPa e sob as condições: i) bocal de 14 mm, ângulo de giro de 240º e velocidade de 30 m h-1; ii) bocal de 14 x 6 mm, ângulo de giro de 270º e velocidade de 55 m h-1. O perfil radial gerado pela rotina computacional com as lâminas aplicadas, geradas com SIMULASOFT, foi igual ao perfil radial obtido em ensaios de laboratório, revelando que o procedimento de cálculo está correto. Uma boa semelhança entre os perfis radiais do aspersor, determinados em ensaios de laboratório e gerados pela rotina computacional, com as lâminas obtidas nos ensaios de campo, foi observada, mostrando que ensaios de campo de sistemas autopropelidos de irrigação podem ser utilizados para a obtenção do perfil radial de aspersores.

Software for calculation of reservoir active capacity with the sequent-peak algorithm

It is presented a software developed with Delphi programming language to compute the reservoir's annual regulated active storage, based on the sequent-peak algorithm. Mathematical models used for that purpose generally require extended hydrological series. Usually, the analysis of those series is performed with spreadsheets or graphical representations. Based on that, it was developed a software for calculation of reservoir active capacity. An example calculation is shown by 30-years (from 1977 to 2009) monthly mean flow historical data, from Corrente River, located at São Francisco River Basin, Brazil. As an additional tool, an interface was developed to manage water resources, helping to manipulate data and to point out information that it would be of interest to the user. Moreover, with that interface irrigation districts where water consumption is higher can be analyzed as a function of specific seasonal water demands situations. From a practical application, it is possible to conclude that the program provides the calculation originally proposed. It was designed to keep information organized and retrievable at any time, and to show simulation on seasonal water demands throughout the year, contributing with the elements of study concerning reservoir projects. This program, with its functionality, is an important tool for decision making in the water resources management.

Pipeline for macro- and microarray analyses

The pipeline for macro- and microarray analyses (PMmA) is a set of scripts with a web interface developed to analyze DNA array data generated by array image quantification software. PMmA is designed for use with single- or double-color array data and to work as a pipeline in five classes (data format, normalization, data analysis, clustering, and array maps). It can also be used as a plugin in the BioArray Software Environment, an open-source database for array analysis, or used in a local version of the web service. All scripts in PMmA were developed in the PERL programming language and statistical analysis functions were implemented in the R statistical language. Consequently, our package is a platform-independent software. Our algorithms can correctly select almost 90% of the differentially expressed genes, showing a superior performance compared to other methods of analysis. The pipeline software has been applied to 1536 expressed sequence tags macroarray public data of sugarcane exposed to cold for 3 to 48 h. PMmA identified thirty cold-responsive genes previously unidentified in this public dataset. Fourteen genes were up-regulated, two had a variable expression and the other fourteen were down-regulated in the treatments. These new findings certainly were a consequence of using a superior statistical analysis approach, since the original study did not take into account the dependence of data variability on the average signal intensity of each gene. The web interface, supplementary information, and the package source code are available, free, to non-commercial users at http://ipe.cbmeg.unicamp.br/pub/PMmA.
