Trasplante renal procedente de donantes con criterios expandidos: análisis del perfil del donante y receptor, evolución clínica y supervivencia a lar…
2015
El trasplante renal es el tratamiento de elección para el paciente con enfermedad renal crónica avanzada, mejorando la calidad de vida y la supervivencia del paciente en comparación con las otras alternativas de tratamiento sustitutivo renal. En los últimos años, la mayor experiencia adquirida en el manejo del paciente trasplantado, junto con la imperiosa necesidad de ofertar riñones para los pacientes incluidos en lista de espera, han motivado la aceptación de injertos renales de donantes cadáver con mayor edad y/o patología cardiovascular. Este tipo de donantes se englobarían en los denominados donantes con criterios expandidos (DCE), definidos por los donantes con edad mayor o igual a 60…
Turbo-Roundabouts: a Model to Evaluate Capacity, Delays, Queues and Level of Service
2012
A turbo roundabout is a particular type of roundabout where entering and circulating lanes are bounded by traffic signs and by non-mountable curbs. The physical separation between lanes, both at entries and on the ring, helps to prevent side collisions crossing the roundabout. The main advantages of turbo roundabouts are: i) reduction in the number of potential conflict points; ii) lower speed of vehicles passing through the intersection; iii) safety conditions at the intersection due to lower risk of side-by-side accidents. These aspects make turbo-roundabouts more appropriate than roundabouts when a higher level of safety has to be guaranteed, particularly in presence of relevant pedestri…
Utilidad de los criterios clínicos para el adecuado diagnóstico de la faringoamigdalitis en la urgencia pediátrica
2019
Fundamentos: Existen dos escalas (Centor y McIsaac) que describen los signos y síntomas frecuentes en la faringoamigdalitis y que determinan la actitud a seguir para su diagnóstico y tratamiento; entre ellas, los criterios de McIsaac son una de las escalas más empleadas. El objetivo del estudio fue determinar el valor predictivo de los criterios de McIsaac en el diagnóstico de la faringoamigdalitis por estreptococo betahemolítico grupo A (EbhGA). El valor predictivo de estos criterios es determinante en la adecuada utilización de la prueba TDR y tratamiento antibiótico. Métodos: Se realizó un estudio transversal cuya población objeto fueron pacientes entre 0 y 14 años atendidos en el Servic…
Observer-Based Stabilization of Stochastic Systems with Limited Communication
2012
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from Hindawi: http://dx.doi.org/10.1155/2012/781542 Open Access This paper studies the problem of observer-based stabilization of stochastic nonlinear systems with limited communication. A communication channel exists between the output of the plant and the input of the dynamic controller, which is considered network-induced delays, data packet dropouts, and measurement quantization. A new stability criterion is derived for the stochastic nonlinear system by using the Lyapunov functional approach. Based on this, the design procedure of observer-based controller is presented,which ensures asy…
Ontology-based clinical decision support system applied on diabetes
2017
Master's thesis Information- and communication technology IKT590 - University of Agder 2017 Medical diagnosis is a multi-step process which is complex as it requires the consideration of many factors. Additionally, the accuracy of diagnosis varies depending on the skill and knowledge a physician has in the medical field. Using ICT solution, the physicians can be assisted so that they can make an accurate decision. Many applications have been developed to enhance physician performance and improve the patient outcome, however, the quality of these applications varies depending on knowledge representation methodology and reasoning approach adopted. Nowadays, ontology is being used in many clin…
Evaluación multicriterio de políticas de uso y gestión de recursos naturales
2014
The purpose of this work is show the characteristics of different environmental economic assessment methodologies, and exposes a case study where possible alternatives addressed to reduce the contamination of a bay with multicriteria approach are evaluated. The results obtained show the effectiveness of multicriteria analysis to evaluate the alternatives for solution of contamination problem in a bay. Economic evaluation of the contamination effects integrated to the environmental, social and economic dimensions through multicriteria techniques allows an alternative planning to solve the environmental problem studied, providing the right decision.
The Complexity of Value and the Evaluation of Complexity: Social Use Value and Multi-criteria Analysis
2018
The “challenge of complexity” is one of the many points of convergence between the Encyclical Laudato si’ and the evolution of post-modern scientific thought. This study aims to analyze how complexity represents the essential element of the profound renewal in the scientific paradigm of the discipline of evaluation, particularly in regard to the theory of value, the categories of value, and the instruments of multi-criteria evaluation. Some contemporary theories of value propose, in fact, a complex source of value, such as surpluses of energy and of information (Ecological Economics) or as the creative and synergistic combination of three surpluses, namely energetic and non-entropic, geneal…

Task-based visual analytics for interactive multiobjective optimization
2020
We study how visual interaction techniques considered in visual analytics can be utilized when implementing interactive multiobjective optimization methods, where a decision maker iteratively participates in the solution process. We want to benefit from previous research and avoid re-inventing ideas. Our aim is to widen awareness and increase the applicability of interactive methods for solving real-world problems. As a concrete approach, we introduce seven high-level tasks that are relevant for interactive methods. These high-level tasks are based on low-level tasks proposed in the visual analytics literature. In addition, we give an example on how the high-level tasks can be implemented a…
Visualizations for Decision Support in Scenario-based Multiobjective Optimization
2021
Reproducibility artifacts for: Babooshka Shavazipour, Manuel López-Ibáñez, and Kaisa Miettinen. Visualizations for Decision Support in Scenario-based Multiobjective Optimization. Information Sciences, 2021. doi:10.1016/j.ins.2021.07.025. Abstract: We address challenges of decision problems when managers need to optimize several conflicting objectives simultaneously under uncertainty. We propose visualization tools to support the solution of such scenario-based multiobjective optimization problems. Suitable graphical visualizations are necessary to support managers in understanding, evaluating, and comparing the performances of management decisions according to all objec…
