A calibration function from change points using linear mixed models
The change point problem is an interesting topic in both cross-sectional and longitudinal settings. In the cross-sectional scenario, the change point problem has been studied extensively. In longitudinal settings, authors ...Universidad Nacional de Colombia Sede Medellín Facultad de Ciencias Escuela de Estadística Estadística. -
A comparative analysis on the seismic behavior of buildings using inerter-based devices: Tuned Mass Damper Inerter (TMDI) and Tuned Inerter Damper (TID)
To accomplish an appropriate performance of tuned mass dampers (TMDs) in building structures subjected to earthquake excitations, considerable amounts of mass must be added at upper floors, which in occasions may result ... -
A computational justice model for resources distribution in Ad Hoc Networks
We propose a computational justice model for resource distribution in ad hoc networks using socially inspired computing and agent-based modeling. Ad hoc networks are self-organizing systems in which there is no central ... -
A computational solution for the software refactoring problem: a formalism toward an optimization approach
Software Refactoring consists in reconstructing the code design of an object-oriented system without affecting the external functionality. Common refactoring tasks, in the initial steps, detect the source code ...Universidad Nacional de Colombia Sede Bogotá Facultad de Ingeniería Departamento de Ingeniería de Sistemas e Industrial. -
A computational solution for the software refactoring problem: from a formalism toward an optimization approach
Abstract: Software Refactoring consists in reconstructing the code design of an object- oriented system without affecting the external functionality. Common refactoring tasks, in the initial steps, detect the ...Universidad Nacional de Colombia Sede Bogotá Facultad de Ingeniería Departamento de Ingeniería de Sistemas e Industrial. -
A conceptual stochastic rainfall-runoff model applied to tropical watersheds
We derive and solve a linear stochastic model for the evolution of discharge and runoff in an order-one watershed. The system is forced by a statistically stationary compound Poisson process of instantaneous rainfall events. ... -
A Contribution to Semi-Automatic Segmentation of Point Clouds
The increase the emerging technologies and the low cost related with 3D data acquisition have allowed researchers to open new doors of research in domains like building information modeling (BIM), in-process inspection, ...Universidad Nacional de Colombia Sede Manizales Facultad de Ingeniería y Arquitectura Departamento de Ingeniería Eléctrica, Electrónica y Computación. -
A contribution to the estimation of kinematic quantities from linear motion blurred images
This thesis introduces a new approach for estimating kinematic quantities, namely the angle the relative speed, and the acceleration from an actual single motion blur image using the Discrete Cosine Transform (DCT). Motion ... -
A criteria based function for reconstructing low-sampling trajectories as a tool for analytics
Abstract: Mobile applications equipped with Global Positioning Systems have generated a huge quantity of location data with sampling uncertainty that must be handled and analyzed. Those location data can be ordered in time ...Universidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Sistemas. -
A deep learning model to assess and enhance eye fundus image quality
Engineering aims to design, build, and implement solutions that will increase and/or improve the life quality of human beings. Likewise, from medicine, solutions are generated for the same purposes, enabling these two ... -
A design procedure for a supervisory control structure in plantwide control
Abstract: This work presents a methodology for designing a supervisory control structure in Plant-wide Control (PWC). First, available PWC structures are discussed focusing on their drawbacks originated from the scarce ...Universidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Química y Petróleos. -
A distributional approach to asymptotics of the Spectral Action
La acción espectral es el concepto natural y apropiado para hablar de una acción en el espacio de triplas espectrales, y fue introducido por primera vez por Chamseddine y Connes en 1997. Después de incluir definiciones y ... -
A espaldas vueltas, memorias muertas. La cotidianidad de Cobija, Puerto Lamar y las tareas de los prefectos (1864-1871)
Resumen: La existencia de Cobija, Puerto Lamar se dio sin descanso y allí se ejecutó el poder de la República. Llegados de distintos lugares y por períodos irregulares, los prefectos de turno resolvían problemas, se ...Universidad Nacional de Colombia Sede Medellín Facultad de Ciencias Humanas y Económicas Escuela de Historia. -
A formalization for mapping discourses from business-based technical documents into controlled language texts for requirements elicitation
Requirements elicitation for software engineering is a process for obtaining, analyzing, and specifying requirements supported by stakeholders—analysts, clients, domain experts, and final users, among others. In this process ...Universidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Sistemas. -
A Framework for Evaluating Maintainability and Performance of Object-Relational-Mapping Tools in Web Application Frameworks
Web Application Frameworks (WAF) and Object-Relational Mapping (ORM) tools reduce the time and effort needed to develop high quality applications. However, there are many of them and choosing the best suited for a particular ...Universidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Sistemas Ingeniería de Sistemas e Informática. -
A framework for interactive training of automatic image analysis models based on learned image representations, active learning, and visualization techniques
Abstract. In this thesis work, the problem of applying active learning for a label efficient training of deep learning models is addressed. Firstly, in chapter one, the problem is introduced as well as the objectives and ...Universidad Nacional de Colombia Sede Bogotá Facultad de Ingeniería Departamento de Ingeniería de Sistemas e Industrial. -
A framework for online prediction using kernel adaptive filtering
Nowadays, the task of predicting in schemas online is an essential field of study for machine learning. The Filters Adaptive based on kernel methods have taken an essential role in this type of task; this is primarily due ... -
