According to the Association of Traffic Accident Victims (AVIACTRAN), on average there are 10 potholes per kilometer of flexible pavement in the city of Lima.This is due to the lack of timely road maintenance by government authorities, as they do not have a system that allows them to identify in real time the different pavement defects to make decisions.To address this problem, this paper proposes the use of the Cascade Trainer GUI algorithm and Python programming to determine defects in flexible pavements.The proposal consists of training the algorithm with images of different pavement defects using mobile phone cameras or drones for data collection and evaluation of the condition of the pavement.The implementation of the model provides a saving of 60% in the detection time of functional defects of the pavement compared to the traditional method.The methodology detects 5 types of defect...

The project describes the design and implementation of an automatic system for detecting defects in plastic crates for glass bottles. In all companies there is damage and defects in their cases, crates, or containers due to constant use, as they are reusable, and therefore this problem causes various economic losses and a decrease in production, especially in beverage companies. This system was designed to solve and prevent the crates from having defects in their base and containing waste inside, to obtain less product losses in the bottle packaging area. In this research, it is proposed to design the automatic system, which consists of training a convolutional neural network with a database of 136 photographs of waste and defects in the boxes that will be taken by the HQ Raspberry Camera; then programmed into the Raspberry the process of activating the engine so that the box is moved to...

In any research process, as we know, the scientific method allows us to detect problems and set objectives. Precisely, the study carried out, by the logical sense of educational research, starts by formulating an objective, based on the problem we determined, it was raised with the following statement: Establish the characteristics of democratic coexistence in the Students of the Non-School Program of the town of Los Ángeles, Tournavista, Puerto Inca 2020. The appropriate method was the analysis that allowed us to understand the texts included in the study. The result was; The correlation index shows that the value of r = 0.69 and r = 0.81, are located in the interval 0.40 ≤ r <0.80 and its interpretation indicates that there is a significant relationship between the theoretical characteristics of democratic coexistence and the practice of behavior of democratic coexistence in the ...

Pertussis is an infectious disease caused by the Gram-negative bacterium Bordetella pertussis. In Peru, actual public health programs indicate that vaccination against B. pertussis must be mandatory and generalized, besides all detected cases must be reported. The objective of this study was to determine the prevalence of B. pertussis among children under five years of age with a presumptive diagnosis of whopping cough in Cajamarca, a region located in northern Peru.

Objective: To determine the diagnostic validity of cytology in the detection of neoplastic lesions of the cervix at the National Maternal-Perinatal Institute during 2019. Materials and Methods: Observational, descriptive, retrospective cross-sectional study. 161 patients who had cervical cytology and histology examinations of the cervix were studied at the INMP during 2019. The information from the medical records with positive and negative results of neoplastic lesions of the cervix was collected through a data collection form. which met the inclusion and exclusion criteria of this study. The SPSS V25.0 program was used for statistical analysis; the Chi-square test was used to calculate the association measures, establishing the level of significance at 5% (p <0.05). Results: cervical cytology obtained a sensitivity of 8.0%, specificity of 64.9%, positive predictive value of 21.2% an...

Objective: To optimize the internal quality control of real-time RT-PCR for the qualitative detection of SARS-CoV-2, using the Cq values of negative and positive controls. Material and method: Prospective-longitudinal study. The sample consisted of 143 Cq values for the negative aliquot and extraction controls, as well as for the positive control. The normal distribution of Cq values was analyzed using the Anderson-Darling (AD) test and randomness tests were applied. Control limits were calculated from 51 Cq values, and then, using control charts, to monitor 92 Cq values obtained from November 2020 to March 2021. Lot acceptance and Cpk indices were evaluated as optimization indicators. The calculations were made with the Minitab program. Results: The batches of Cq values were accepted and Cpk indices higher than 1.33 were obtained for the three types of cont...

Entre marzo del 2016 y el 24 de enero 2019 se registraron a nivel nacional 2.539 delincuentes con orden de captura por el Ministerio del interior (MININTER), donde solo fueron capturados 1413 y 1126 se encontraron en libertad generando inseguridad ciudadana en el Perú, siendo el 25.5% de la población entre 15 y más años en algún momento han sido víctimas por aquellos criminales que se encuentran libres por alguna modalidad delictiva. Debido a las razones anteriores, es necesario reducir el índice de inseguridad ciudadana en la sociedad. Así mismo, el estado destina dinero en programa de recompensa por delincuentes con orden de captura, generándose comunicación de diversa índole, inclusive información inexacta y por ende movilizando a la policía de manera innecesaria, impactando en el gasto de recursos. La presente investigación tiene como objetivo realizar Diseño e Impleme...

El objetivo del presente trabajo es diseñar una red neuronal en un PLC S7-1200 para la detección de color, en procesos industriales de clasificación. En principio en el trabajo se describen los aspectos del diseño de investigación y justificación del estudio, para luego presentar las bases teóricas que permita comprender la implementación de las redes neuronales en el controlador SIEMENS S7-1200. A partir del análisis de la información obtenida se evalúan aspectos técnicos para determinar la eficiencia del sistema basado en redes neuronales aplicados en controladores industriales. Se logro diseñar la red neuronal basada en una capa con tres neuronas con función de activación SIGMOIDE y con tres entradas y tres salidas. Las cuales determinan los colores de detección basado en las frecuencias de entrada a la red neuronal. Por último, se logró determinar la eficiencia prom...
