Full textWithin the non-traditional agricultural sector, fresh mango is the fifth most exported Peruvian fruit, with an average annual growth of 12.92 percent from 2002 to 2019. The United States is the second destination for Peruvian mango exports, covering an average of 24% percent of total sales in 2019. Given this, this research seeks to determine the factors that influenced the export of fresh mango from Peru to the United States during the period 2002 - 2019. The study had a mixed approach, with a descriptive, correlational and causal scope; With a non-experimental longitudinal design, where the variables Production, FOB Price, Exchange Rate, US Demand and US GDP were analyzed. In addition, of a descriptive nature, the variables Business Management, State Support and Climate were analyzed. For the quantitative analysis, information was obtained from secondary sources such as Adex Data Trade, BCRP, World Bank, MINAGRI and Bureau of Economic, where the data was processed through a multiple linear regression model. While, for the qualitative analysis, the semi-structured interview technique was used in which thirteen key actors belonging to entities of the private sector, public sector and related unions were interviewed where the information was processed through the Atlas Ti tool. Regarding the results of the investigation, it was concluded that the variables national production and demand from the United States influenced the export of fresh Peruvian mango to the United States.

Full textThis research work aims to apply Regression Analysis and Machine Learning (ML) techniques to improve the results of estimating over dilution in stopes mined by Sub Level Stoping (SLS) method at Compania Minera Condestable (CMC) through the generation of regression equations and code in Python language for ML techniques. For the estimation of over dilution, the reconciliations of stopes mined with the SLS method for the period 2017-2019 were analysed with the application of the techniques: Multiple Linear Regression Analysis (MLRA), Multiple Non-linear Regression Analysis (MLNRA) and Machine Learning (ML) methods such as Support Vector Machine (SVM) and Random Forests (RF), which allowed comparisons of the results at predictive and technological level with the O'Hara methodology currently applied at CMC for the estimation of over dilution of SLS stopes. The application of the afore mentioned techniques involved operational variables such as: level, dip, density, burden, spacing, height, length, width, RQD, RMR and tonne per metre drilling (TMP) ratio of the evaluated stopes, while the objective or dependent variable was over dilution. This initially identified that the ARLM and ARNM regression techniques improved O'Hara's R2 determination coefficient by 5.5% and 4.4%. Then, with the application of machine learning tools it was identified that both techniques (SVM and RF) achieved the improvement by 0.3% and 18.5% respectively. This resulted in a reduction of the estimated cost difference obtained with the O'Hara methodology related to the additional cost of loading and transporting broken stock from the dilution.

Full textThe present investigation is mainly related to the use of the Standard Penetration Test (SPT) and the Direct Shear Test, through these tests results were obtained that were used to formulate a correction expression. The study was carried out on sandly soils with a percentage of fine less than 12 % in the Lima districts of Villa El Salvador and Ventanilla. Due to the great diffusion and use of the Direct Shear Test it is of utmost importance that the results obtained are as reliable as possible, since it depends on the design of foundation structures, slopes, embankments, among others. However, there is great difficulty in obtaining undisturbed samples from sandy soils, which induces to Direct Shear tests being carried out, reshaping the specimen to its natural density, moisture content, compactness and others, this could generate a considerable variation in the results (soil resistance parameters). Based on the above, it is considered necessary to find a way to counteract this problem, for this reason it is proposed to formulate a correction expression for the friction angle obtained in the Direct Shear tests of remoulded samples. For the formulation of said expression, the Microsoft Excel program was used to perform a multiple linear regression with the variables related to the friction angle, resulting in a correction expression that improves the friction angles of the Direct Shear Test by 63.69 %.

Nas engenharias, é fundamental estimar o tempo de vida útil das estruturas construídas, o que neste trabalho significa o tempo que os íons cloretos levam para atingirem a armadura do concreto. Um dos coeficientes que influenciam na vida útil do concreto é o de difusão, sendo este diretamente influenciado pelo grau de saturação (GS) do concreto. Recentes estudos levaram ao desenvolvimento de um método de medição do GS. Embora esse método seja eficiente, ainda assim há um grande desperdício de tempo e dinheiro em utilizá-lo. O objetivo deste trabalho é reduzir estes custos calculando uma boa aproximação para o valor do GS com modelos matemáticos que estimem o seu valor através de variáveis ambientais que influenciam na sua variação. As variáveis analisadas nesta pesquisa, são: pressão atmosférica,temperatura do ar seco, temperatura máxima, temperatura mínima, taxa de evaporação interna (Pichê), taxa de precipitação, umidade relativa, insolação, visibilidade, nebulosidade e taxa de evaporação externa. Todas foram analisadas e comparadas estatisticamente com medidas do GS obtidas durante quatro anos de medições semanais, para diferentes famílias de concreto. Com essas análises, pode-se medir a relação entre estes dados verificando que os fatores mais influentes no GS são, temperatura máxima e umidade relativa. Após a verificação desse resultado, foram elaborados modelos estatísticos, para que, através dos dados ambientais, cedidos pelo banco de dados meteorológicos, se possam calcular, sem desperdício de tempo e dinheiro, as médias aproximadas do GS para cada estação sazonal da região sul do Brasil, garantindo assim uma melhor estimativa do tempo de vida útil em estruturas de concreto.
In engineering, it is fundamental to estimate the life-cycle of built structures, which in this study means the period of time required for chlorides to reach the concrete reinforcement. One of the coefficients that affect the life-cycle of concrete is the diffusion, which is directly influenced by the saturation degree (SD) of concrete. Recent studies have led to the development of a measurement method for the SD. Although this method is efficient, there is still waste of time and money when it is used. The objective of this study is to reduce costs by calculating a good approximation for the SD value with mathematical models that predict its value through environmental variables that affect its variation. The variables analysed in the study are: atmospheric pressure, temperature of the dry air, maximum temperature, minimum temperature, internal evaporation rate (Pichê), precipitation rate, relative humidity, insolation, visibility, cloudiness and external evaporation rate. All of them were statistically analysed and compared with measurements of SD obtained during four years of weekly assessments for different families of concrete. By considering these analyses, the relationship among these data can be measured and it can be verified that the most influent variables affecting the SD are the maximum temperature and the relative humidity. After verifying this result, statistical models were developed aiming to calculate, based on the environmental data provided by the meteorological database and without waste of time and money, the approximate averages of SD for each seasonal station of the south region of Brazil, thus providing a better estimative of life-cycle for concrete structures.

A produção da cana-de-açúcar é destaque no cenário econômico do estado São Paulo, dessa forma confirma-se a necessidade do monitoramento dessa cultura, de maneira a contribuir com melhorias em decisões e planejamentos operacionais. A produção total e a produtividade da cana-de-açúcar são fatores de grande interesse para os agricultores, pois é a partir dessa informação que a programação das operações são realizadas, porém, essas estimativas não possuem métodos de alta precisão e confiança em amostragens não destrutivas. O homem possui excelente capacidade de analisar e interpretar resultados, mas também está sujeito a subjetividades em suas avaliações. A análise empreendida no trabalho teve como objetivo a elaboração de modelos matemáticos que expliquem a produtividade da cana-de-açúcar por meio das técnicas de geoprocessamento e sensoriamento remoto. O experimento foi realizado na área de produção comercial da Agrícola Rio Claro, parceira do grupo Zilor, que está localizada nos municípios de Lençóis Paulista e Pratânia, possui aproximadamente 6000 hectares, com altimetrias variando entre 600 e 700 metros. Para a coleta das informações espectrais, utilizou-se as imagens do satélite Landsat 8, com órbita/ponto em 221/076. Nos resultados do trabalho realizado, constatou-se que as modelagens foram satisfatórias, variando o coeficiente de determinação entre 0,15 a 0,97. Sendo que em períodos com elevados coeficientes de determinação, podem geralmente ser encontradas áreas de forma aglomerada, o que sugere uma menor incidência de variáveis. Enquanto que em períodos com coeficientes de determinação baixos, muito provavelmente foram obtidos devido a outros fatores listados terem ocorrido como dispersão dos talhões na área, classes de solo, precipitação e variedades da cultura, provavelmente distintos.
The production of sugarcane is a highlight in the economic scenario in the state of São Paulo, thus it confirms the need of monitoring this culture, in order to contribute to improvements in making decisions and operational planning.The production and productivity of sugarcane are factors of great interest to farmers, because, from this information the planning of operations is performed out, however, these estimates do not have high precision and reliable methods for non-destructive sampling.The human has an excellent ability to analyze and interpret results, but may also be affected by the subjectivity of their evaluations.The analysis undertaken in this work aimed at the development of mathematical models to explain the productivity of sugarcane through geoprocessing and remote sensing.The experiment was conducted in commercial area of Agrícola Rio Claro, partner of Zilor group, which is located in Lençóis Paulista and Pratânia, of approximately 6000 hectares, with altimetry ranging between 600 and 700 meters. For the collection of the spectral information, it was used the images of the satellite Landsat 8, with orbit/point 221/076. The results of the work, it was found that all the modeling were satisfactory, varying the coefficient of determination between 0.15 to 0.97. Given that, in periods with high coefficients of determination areas may be generally found in clusters, suggesting a lower incidence of variables. While in periods of low coefficient of determination, it was most likely obtained due to other factors listed of having occurred such as a dispersion of the plots in the area, soil types, rainfall and varieties, probably distinctly.
