Predicción de variables operacionales en el proceso de Producción de Crudos por Segregación Gravitacional Asistida por Vapor (SAGD)

Evaluación de la calidad en uso de sitios web asistida por software: SW-AQUA

—This paper describes the development of a tool for quality in use assessment of web sites following ISO/IEC 9126­4 model guidelines. The tool allows to the evaluator obtains quality in use metrics incorporated in the standard. The evaluation results are based on four characteristics: effectiveness, productivity, safety and satisfaction. The softwa re tool SW­AQUA wa s developed according to un...

Simulación de un Proceso de Producción de Marquillas

Similitud de series de tiempo basada en longitud de patrones de la transformada por aproximación móvil

We propose to measure the similarity of time series using the length of the patterns given by the Moving Approximation Transform. In addition, we propose a method for automatic selection of the time window for this transform and a method for visualization of the time intervals in which the similarities between the two series occur. The method is applied to time series of the stock values of the...

Minería de textos para el análisis del subregistro de lesiones por causa externa en el servicio de urgencias de un hospital de tercer nivel

External Cause of Injuries (ECI) represent a serious health problem, however diagnosis using nonspecific codes may underestimate their severity. This situation is common in many hospitals, affecting the resources allocation and health priorities. Analyzing data from the emergency department of a hospital, four predictive models were implemented: Text-Logistic regression (TF-IDF), logistic regre...

Modelo dinámico de las afectaciones del tiempo de ciclo kanban en el flujo de producción de una línea de ensamble

This article describes the dynamic model of assembly process of reducer is presented as part of an activity performed in a workshop kanban simulation aimed at students of industrial engineering. The main objective of the model developed is to analyze the behavior of inventory levels workstations and accumulations of kanban cards (production orders) derived from the effects of the cycle time kan...
