Arquitectura tecnológica para la asignación de ambulancias en ciudades inteligentes
(Universidad Santiago de Cali, 2020) Ospina Tobón, Luis Carlos; Dinas, Simena
The ambulances assignment to attend patients involved in accidents is one of the biggest problems in many third-world countries. It is a problem due mainly to two factors: mobility and limited resource availability. Traditionally, the problem is addressed by requesting the patient assistance by using radio broadcasting to all ambulance operators. The problem is that some notified ambulances may not be close to the accident, others could be on duty, on their way to attend other accidents, or not available. Nonetheless, it has also been notices that broadcasting generates competition among ambulances, or even lack of assistance to patients when many operators decide to attend the same accident. Furthermore, the competition to assist, has sometime generated new accidents. In other cases, negative impacts have been seen from the economic, ethic, social, politic, and mobility perspectives. Because of this situation, A Technological Architecture for the Assignment of Ambulances in Smart Cities was designed. Additionally, an intuitive and easy-to-use functional prototype was developed, applying the Design Thinking methodology. It is a proposal that puts technology at the service of community and aims to improve citizen quality of life, as proposed in the smart city manifest. This proposal was made under the cloud computational paradigm, which deploy the front-end of a mobile application for medical emergency real-time notifications. Additionally, the back-end manages the business logic to assign ambulances in a intelligent way and taking into account availability and georeferencing. The application was made possible by using technologies such as React JS, React Native, Firebase, Realtime Database, Cloud Functions, Google Maps, and Directions API. The software architecture is completely functional, scalable, and adequate. It has a TRL 4 maturity level, and complies with Jakob Nielsen’s 10 usability principles, giving a solution to the outlined needs. Tests was focused on Emergency logging and ambulance assignment, and in 98% of the cases, the prototype chose the nearest ambulance, the response was lower than 2 seconds, and the system behaved according to the necessary events to give solution to the problem.

(Universidad Santiago de Cali, 2019) Erazo Cardona, Carlos Alberto
Building houses process in construction companies is affected by fallen negotiations before delivery of the living place, unknowing the reasons for this situation. In building sector there is no a model that allows the characterization of customer profile linked to the commercialization process that would contribute to mitigate the risk to business agreement. As several productive sectors begin to apply data mining, adaptations of traditional methodologies for data mining arise, which solve particularities of these sectors. This paper proposes a characterization model of customer profile adapted to building sector with data mining that includes the results obtained in case study in a building company. The Knowledge Discovery in Databases (KDD) methodology was followed with an adaptation or contribution found in literature that identified own characteristics of building industry in the approach, design, mining techniques, pattern evaluation and validation that allowed generalizing the model. With case study, a design for the data warehouse based on the multidimensional data model using the star schema was proposed. It was proved that classification, regression and clustering techniques are recommended to solve the problem and finally the proposal for data mining techniques evaluation and validation was presented. The generalization of the characterization model of customer profile, confirmed the tendency and requirement of the productive sectors to have data mining models specific to their needs.

The result of this investigation generated a prototype of the device with a cost of 1% with respect to the value that has as budget for the system of biometric cameras of the stadium, using the same human resource that currently supports logistics of the event, having as the only additional action the pressing of a button for the taking of images of the exact moment that the event is happening, this proposal makes that less time is required to make analysis to the evidences, since the images will be only of situations that present facts of bad behavior of the fans. This type of tools is part of the persuasive technologies that contribute to the strategies of change on the part of the fan towards a good behavior, to achieve that these scenarios are safe and become a culture for future generations.
Modelo multiclasificador aplicando minería de datos para el diagnóstico médico utilizando datos abiertos
(Universidad Santiago de Cali, 2019) Bolaños Ramírez, Harold Ferney; Dinas, Simena
In order to understand, analyze and eventually make use of a massive amount of data, a multidisciplinary approach has been proposed: data mining, it consists in the process of identifying patterns from massive databases. Data mining can be used in several fields: mobile computing, web mining, financial analysis, crime analysis, engineering, management and medicine. In medicine, data mining techniques can be used by researchers for the diagnosis and prediction of sundry diseases. Researchers have widely used several statistical analysis and data mining techniques to improve the accuracy in the diagnosis of the different diseases in medical care. The use of individual data mining techniques reveals an acceptable level of accuracy to determinate the diagnosis of the disease. Sets or combinations of classifiers have produced promising results, improving accuracy, reliability and, most importantly, extensive coverage in many different and practical applications. In this study, we evaluated the application of feature selection methods and the use of a set of three classifiers based on three different mixing strategies using open diabetes and breast cancer databases contained in the ICU data repositorio with the goal of supporting decision-making in medical diagnosis. The effectiveness of the combinations was measured using three commonly accepted metrics, as well as the response times in the construction of the models. Analysis of the results reveal that the sensitivity, specificity and percentage of classification are higher compared to the individual techniques and provides the basis for establishing an improved multi-classifier model.

(Universidad Santiago de Cali, 2019) Gaviria Chavarro, Javier
level. Despite this, they do not delve into information on statistical methods related to non-parametric statistics. This situation arises due to the large number of topics that have the inferential statistics in addition to its long extension. For this reason, a virtual learning object was created for the non-parametric statistical methods of Kruskal Wallis, Mann-Whitney U and Wilcoxon. These methods are relevant for the investigations analysis performed with small samples (less than 30) which do not comply with the statistical assumptions. The main purpose of this research is teaching and learning these three statistical tests. To achieve this, the methodology of construction of virtual learning objects proposed by Borrero and Cruz was implemented to support the training of students in the biostatistics area. The objects were evaluated by experts through the LORI instrument, showing a quality level in the medium-high interval according to the final weighting. The evaluation instrument indicated that the virtual learning object is suitable for the purpose and objectives set.
