El modelado BPMN para la gestión de procesos permite aplicar una notación gráfica estandarizada para el modelado de procesos de negocio, así como una notación estándar que es fácilmente legible y entendible por parte de todos los involucrados e interesados (stakeholders), como los analistas de negocio, los desarrolladores técnicos, los gerentes y administradores del negocio. Bajo este contexto se llevó a cabo un diagnóstico de la Oficina General de Informática en la Universidad Nacional del Centro del Perú, donde se determinó que muchos de los procesos, actividades y procedimientos que se llevan a cabo en la actualidad no se han establecido en alguna directiva y/o normativa vigente. Se propuso una nueva estructura organizacional, que permitió una definición más puntual de los procesos requeridos en la Oficina General de Informática, utilizando el software Bizagi. Se evid...

The thesis has two purposes: The first one is to build a mathematical model that better approximates (with respect to the mathematical model in [2]) to the behaviour of the wine fermentation process with the addition of certain amount of nitrogen at some instant of time, based in [2]. This mathematical model is described by mean ordinary differential equations including some parameters which will be identified solving some optimization problems. The second purpose of the thesis is to study the improved model but introducing some control variables in order to stabilize in an appropriated sense the corresponding dynamical system of the new model. This is a kind of MIMO nonlinear system control problems and will be solved using the tools in [6].La tesis tiene dos objetivos: El primero es construir un modelo matemático que aproxime mejor (con respecto al modelo matemático en “Modeling th...

The mathematical relationships obtained denote the complexity of the operation in the leached and adsorbed gold stage on activated carbon; since significant losses of gold in solution occur in real metallurgical operations. Similarly, in the adsorbed gold operation, it reveals its high kinetics at the beginning and tends to decrease as the process progresses; eventually reaching the maximum gold load that the carbon can accommodate, and then showing the opposite trend. Furthermore, varying the concentration of carbon affects the adsorption operation; that is, the kinetics of gold adsorbed on carbon decreases over time, but the operation has higher kinetics with a larger volume of carbon during adsorption. The mentioned aspects are made possible by establishing the respective mathematical model of gold in barren solution and gold loaded on carbon; then optimizing with Solver - an Excel to...

This paper considers the proposal, development and numerical simulation of a system that models the behavior of the treatment of HIV-1 using antiretrovirals. The system defined for three dependent variables of the variable t, denoted by X(t)=(x1 (t), x2 (t), x3 (t)) represent the amount of T Lymphocytes "Helpers" (CD4), number of Cytotoxic T Lymphocytes (CD8) Viral load and infection process of HIV-1 at any time t, respectively. The assembly consists of a Nonlinear Ordinary Differential Equations system whose existential domain represents time system evaluation process of infection and viral clearance in a patient with HIV-1. This set of states of Nonlinear Dynamic System, associated with the initial value condition is called Cauchy problem. There are few studies related to the solution of this system, found some of the study are reduced to two variables and others without obtaining the ...
