A set membership approach to oxygen transport modeling with unmodeled dynamics
No full textDissolved oxygen concentration in a cultivation broth is an important variable for bioprocesses operation. The oxygen transfer from air to liquid is determined by the oxygen transfer coefficient, usually regulated by the air flow rate and agitation speed. However, many microscopic phenomena are involved in the oxygen transfer. In this paper, a deterministic estimation method for the oxygen transfer coefficient of a bioreactor is proposed. The inclusion of probe dynamics and assumptions of deterministic undermodeling errors improve estimation results when compared to classic least squares methods. The approach is based on Set Membership techniques, it allows the user to fix hard bounds on the effect of unmodeled dynamics and provides feasible coefficient intervals by means of convex optimization problems. Results from a laboratory-scale bioreactor show the effectiveness of the proposed scheme and its advantages over a least-squares solution

Eficacia y pertinencia de la cadena perpetua frente a la violencia sexual contra niños y niñas
No full textThis research article deals with an analysis of the effectiveness and relevance of the criminal measure of life imprisonment against sexual violence against boys and girls. For this reason, the concepts of effectiveness and relevance of the sentence are examined in the light of the theory of criminal law, finding that the effectiveness in this matter depends on the materialization of the purposes of the sentence, that is, resocialization, prevention general and special, and that relevance is subordinated to the adequacy of the measure with respect to the legal system. Based on the above, a view of the measure is introduced from a guarantee criminological approach, that is, taking into account the limits of criminal law and the guarantee of human dignity. Finally, the legal and doctrinal dogma of sexual violence against boys and girls is specified through its normative, jurisprudential and theoretical references.Este artículo de investigación aborda un análisis sobre la eficacia y pertinencia de la medida penal de cadena perpetua frente a la violencia sexual contra niños y niñas. En razón de ello, se examinan los conceptos de eficacia y pertinencia de la pena a la luz de la teoría del derecho penal, encontrándose que la eficacia en esta materia depende de la materialización de los fines de la pena, esto es, resocialización, prevención general y especial, y que la pertinencia se halla subordinada a la adecuación de la medida respecto del ordenamiento jurídico. A partir de lo anterior, se introduce una mirada de la medida desde un enfoque criminológico garantista, esto es, tomando en consideración los límites del derecho penal y la garantía de la dignidad humana. Por último, se precisa la dogmática jurídica y doctrinal de la violencia sexual contra niños y niñas a través de sus referencias normativas, jurisprudenciales y teóricas

Propuesta metodológica basada en vigilancia tecnológica para el desarrollo del marco regulatorio de las fuentes no convencionales renovables de energía en Colombia. Estudio de Caso.
No full textEl presente documento realiza una descripción general de las políticas para la promoción e integración de las fuentes no convencionales de energía renovable en países de referencia y en Colombia, donde se identifica la brecha que existe entre países con políticas maduras y alta penetración de las energías renovables en la matriz energética con respecto a Colombia y la región. Posteriormente se presenta la propuesta metodológica basada en vigilancia tecnológica e inteligencia competitiva validada mediante un estudio de caso para energía eólica, se sugieren criterios para identificar las necesidades de vigilancia, así como fuentes de información y temáticas tendenciales orientadas a facilitar la incorporación de criterios, factores y variables de carácter anticipativo para el desarrollo del marco regulatorio de la generación de energía eléctrica mediante el consumo sostenible de recursos. Finalmente se presenta un análisis de contexto, donde se resalta el poder dominante que mantienen las grandes compañías de generación de energía eléctrica en el país, la dependencia del crecimiento económico y los ingresos de la nación con dependencia de la industria extractiva que contrasta con los objetivos de desligarse de las fuentes de emisiones contaminante. Así como elementos de carácter social como el acceso a la energía, subsidios, carencia de infraestructura y la falta de información. Otro aspecto relacionado con el contexto de los proyectos de infraestructura para fuentes renovables es la efectiva transferencia de beneficio para las comunidades en el área de influencia, la atención prioritaria de necesidades básicas insatisfechas y la falta de criterios para determinar el impacto real sobre los objetivos de desarrollo sostenible.Abstract: This document initiates with a general review of the renewable energy resources policies in referenced countries as well as in Colombia, there is identified a gap between the geographies with high penetration of the renewable energies in the generation mix and high level of maturity in policy with respect to Colombia and the region. After that, the proposed methodology based on competitive intelligence is presented. A study case for wind power is analyzed to validate the methodology. A criterion for competitive intelligence needs survey and key intelligence topics identification are given, also information sources and database are object of recommendation. All of this intended to identify tendencies and issues that facilitate the incorporation of criteria, factors and variables to anticipate the deployment of renewable energy for electricity generation with the use of sustainable resources. Finally a context analysis is presented, where is identified the dominance of traditional big generation companies, the dependence of economic growth and incomes of the country by the extractive industry which has a contrast with the objective of zero emission power industry. Also is issued a weakness in aspects like benefit transfer for communities, information to the end user, priority in attention of unsatisfied basic needs and lack of criteria to measure the real effectiveness in accomplishment the sustainable development goals.Maestrí
Gain-Scheduled Oxygen Concentration Control System for a Bioreactor
No full textThis article presents a multi-variable control strategy for the regulation of Dissolved Oxygen Concentration in a stirred laboratory-scale bioreactor. The controller manipulates the airflow and agitation speed in the reactor. Departing from a mechanistic model that relates the manipulated variables and the oxygen transfer coefficient, linearized local models of the process are obtained. It is observed that there is high variability in the process behavior with the operating point. Then, a Gain-Scheduled controller is proposed. The strategy varies the agitation speed employing a PI control law and varies the air flow according to a switching law that detects saturations in the manipulated variables. The proposed strategy is evaluated in simulation and implemented in a real bioreactor. Results show that the strategy is able to regulate the oxygen concentration in a wide range of operating conditions
