El presente trabajo de investigación presenta un nuevo modelo para la implementación de e-learning personalizado. El modelo propuesto considera el nivel de habilidades o conocimiento que un estudiante tiene en un tema en particular; esto se determina a través de una prueba de entrada (pretest); este aspecto es muy importante para evitar problemas conocidos como la ansiedad o el aburrimiento de acuerdo a la teoría de flujo. Adicionalmente, para determinar la secuencia óptima de recursos de aprendizaje para un estudiante, se trabajó de manera complementaria con dos técnicas de inteligencia artificial: El Razonamiento Basado en Casos (CBR) y el Aprendizaje por Refuerzo (Q-Learning). El Razonamiento Basado en Casos, permitió en base a casos de éxito del pasado, determinar la secuencia de recursos de aprendizaje más apropiada para el estudiante; y en caso de no haber casos muy simil...

Studies of urban transport networks in many cities are not well focused, since they do not include tools for their planning and control, making decisions to solve the multiple problems regarding traffic congestion expensive and not adequate, generating discomfort in the users, and many times it aggravates the problems, since its impact is not evaluated. Currently exist a variety of simulators that are helpful for traffic simulation and online monitoring. An alternative to this are traffic simulators, which currently exist in variety, however, they are not easily accessible, a formal study and a relationship with the research center that provides it is required, their personalized reports are limited and they comply to another reality. In the present work, six frequent cases of urban transport networks in Lima are modeled, simulated and validated: intersection, oval, union, by-pass, clove...

The Vehicle Routing Problem considers the design of sets of minimal cost routes, from an originated point knowned as deposit to an ended point. In this problematic situation, a key element in delivery systems is the sequencing of transport units, determined by the requirement of customers. The aim of this article is to present a new method of solving the problem of allocation of routing companies with the need to distribute products, through new models that use different algorithms. The model designed from the analysis of a set of metaheuristics, develop viable options to solve the daily problem of how to allocate and distribute products, from the company to customers, with efficiently and effectively ways.

This study aims to evaluate the future of confirmed cases of Covid-19 in Peru, using the Gompertz nonlinear regression model. The data were obtained from official reports of the Peru Ministry of Health (MINSA). The accumulated value of fatal cases was subjected to iterative analysis by the non-linear least-squares method to achieve a model. Given the first-order derivative of the predictive model was obtained the daily fatal cases curve. Using the fatality rate as the proportion between infected and fatal cases, both of them would also provide days average lag to estimate the epidemic curve. For the moment, the predictive model suggests that Peru would be in a slow descent in the epidemic curve, moving away from the peak of contagions per day. The trend of reaching about 550 thousand infected and 19 thousand deaths until the end of the year 2020. The predictions of the mathematical model...

The study minimizes the cycle waiting time of loading and hauling equipment between loading points of the underground mining operation and unloading points on surface. For this purpose the existing loading and hauling system is first analyzed. Present system consists of four underground loading points and 4 unloading spots on surface. The waiting cost is estimated and then the increment in loading points underground is proved for reducing haulage cost which is a bearing component of the mining cost. By applying queuing techniques the possible reduction in waiting cost is obtained by increasing the number of loading points. The information gathered comes from loading and hauling times measured at site. Evaluated variables were number of loading points vs. waiting time cost of haulers and unit cost of underground ore and waste bins.

In this work, a basic epidemiological model is used to determine the evolution of COVID-19 in each of the regions of Peru. For determining the parameters of the model which characterize a certain epidemic, the reports of infected, deceased and recovered people provided by the Regional Health Management of Peru are used. As a result, we obtained the configuration of the infected, susceptible and removed which are consistent with the existing bibliography, thus we also obtain a time interval in which there is a considerable number of infected, the maximum number of infected and the date on which it occurs.

This study presents a simplified analytical model for ore deposit evaluation for either an orebody in a stage of project or in actual exploitation. Model variables are average ore grades of contained metals, annual rate of ore mined and ore deposit reserves. The model estimates annual net cash income, return on investment and net value of the ore deposit at the investor’s fixed annual interest rate after discounting the total investment. An example of the model application is shown for a copper-zinc ore deposit mined by the open pit method. All three variables of the model are considered to be the most important factors and were chosen from a number of known variables of the annual income flow. The criteria for variables selection follow the 80/20 Pareto rule which shows that 20 percent of the factors account for 80 percent of the results. The surface mining method was chosen by compar...
