The projection of a long-term strategic plan such as the "COPNIA 2036 Prospective Model"; Expresses a vision in line with the demand that the professional market of the country and civil society has rooted, and that is being strengthened by the management and easy access to information. lt is time to rethink public institutions and allow their installed capacity to create added values for their missions, making use of information and communication technologies; And in general of the vertiginous technological advance that we witness in the fourth industrial revolution that, according to Klaus Schwab, author of the book "The fourth industrial revolution", will fundamentally change the way we live, work and relate. In its scale, scope and complexity, the transformation will be different from anything that mankind has experienced before. The possibility of executing a prospective model for COPNIA implies the consolidation of an entity that is strengthened by looking for ways to anticipate what is to come around it and that the result will be to build a better future for it and Expand the social benefit of their actions in the society of our country.

Dada la importancia de la salud en el desarrollo económico y social de un país y el surgimiento de un cambio radical en la prestación del servicio de salud por medio de la Atención Primaria en Salud–APS- se presenta la siguiente investigación como una propuesta metodológica para la asignación de cuadrillas de APS, con el objetivo de contribuir a la planeación coordinada y continua de dichos servicios por medio de técnicas de simulación. Se integran técnicas de Scheduling, de optimización y de simulación; se tiene en cuenta la composición de costos y algunas variables sociales durante el desarrollo de la investigación. Este modelo integral de técnicas de simulación para la asignación de cuadrillas de APS, se convierte en un primer paso para abordar futuros proyectos de mayor complejidad que se puedan abordar institucionalmente o incluso en uno o varios proyectos de investigación doctoral. Para posteriores investigaciones se podrá abordar temas tales como tratamiento de vectores epidemiológicos, condiciones particulares de cada población (en función del estado de salud) y la composición de las cuadrillas de salud

Imagen de apoyo de Hybrid behaviour orchestration in a multilayered cognitive architecture using an evolutionary approach

Por: Oscar Javier; Antonio Jiménez Romero López | Fecha: 2008

Managing and arbitrating behaviours, processes and components in multilayered cognitive architectures when a huge amount of environmental variables are changing continuously with increasing complexity, ensue in a very comprehensive task. The presented framework proposes an hybrid cognitive architecture that relies on subsumption theory and includes some important extensions. These extensions can be condensed in inclusion of learning capabilities through bio-inspired reinforcement machine learning systems, an evolutionary mechanism based on gene expression programming to self-configure the behaviour arbitration between layers, a co-evolutionary mechanism to evolve behaviour repertories in a parallel fashion and finally, an aggregation mechanism to combine the learning algorithms outputs to improve the learning quality and increase the robustness and fault tolerance ability of the cognitive agent. The proposed architecture was proved in an animat environment using a multi-agent platform where several learning capabilities and emergent properties for self-configuring internal agent’s architecture arise.

Imagen de apoyo de Nitrogen Transformation and Removal in Maturation Ponds: Tracer Experiments with 15N Stable Isotopes in The United Kingdom in Summer

Por: Miller Alonso; Mara Camargo Valero | Fecha: 2007

The mechanisms and pathways by which nitrogen in its various forms is removed from waste stabilization ponds (WSP) have been a subject of much debate. In order to improve current understanding of the dynamics of inorganic and organic nitrogen removal in WSP systems, a study using stable nitrogen isotopes (15N) was undertaken on an experimental pilot-scale WSP system at Esholt Wastewater Treatment Works (Bradford, UK) in summer 2005 and 2006. A primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N-labelled algae (Chlorella vulgaris) to track nitrogen transformations and removal associated with ammonia volatilization, nitrification, and algal uptake and its subsequent sedimentation and retention/hydrolysis in the sludge layer. Stable isotope analysis of 15N, in conjunction with performance indicators, revealed that total nitrogen is poorly removed (? 8%) but ammonium nitrogen removal is very good in summer (effluent concentration <2 mg NH4 + -N/L). The nitrogen cycle in maturation ponds is dominated by biological uptake as ammonium nitrogen is rapidly transformed into algal biomass as suspended organic nitrogen which then either leaves in the pond effluent or is sedimented as dead cells. Ammonia removal by volatilization makes little or no contribution to nitrogen removal and biological nitrate uptake prevents classical nitrification. Thus algal uptake of ammonium and subsequent sedimentation and retention in the sludge layer, after parti al ammonification of the algal organic nitrogen, appears to be the dominant mechanism for permanent nitrogen removal in maturation ponds during warm summer months in England.

Imagen de apoyo de Hybridization of cognitive models using evolutionary strategies

Por: Oscar Javier; Antonio Jiménez Romero López | Fecha: 2009

Incorporating different kinds of micro-theories of cognition and modulating several mechanisms to unify all the recommended actions and outputs of an Intelligent System when a huge amount of environmental variables are changing continuously with increasing complexity, may become a very comprehensive task. The presented framework proposes an Hybrid Cognitive Architecture that relies on integrating of emergent systems approaches —connectionist and autopoietic systems—, and cognitivist approaches, in order to combine implicit and explicit processes necessary in developing cognitive skills. The proposed architecture includes different kinds of learning capabilities at each cognitive level which grant to the architecture a big plasticity. In addition, the propounded attention module includes an evolutionary mechanism based on gene expression programming to evolve a set of eligibility conditions in charge of modulating the coalition/ subordination of specialized behaviours, taking into consideration the theatre metaphor for consciousness. Finally, a co-evolutionary mechanism is proposed to propagate behaviours and knowledge between cognitive systems —Agents— on the basis of memetic engineering. The proposed architecture was proved in an animat environment using a multi-agent platform where several emergent properties of self-organization arose.

Imagen de apoyo de Modulation of multi-level evolutionary strategies for artificial cognition

Por: Oscar Javier; Antonio Jiménez Romero López | Fecha: 2009

There are several theories of cognition, each taking a different position on the nature of cognition, what a cognitive system should do, and how a cognitive system should be analyzed and synthesized. From these, it is possible to discern three broad classes: the cognitivist approach based on symbolic information processing representational systems; the emergent systems approach embracing connectionist systems, dynamical systems, and enactive systems, all based on a lesser or greater extent of principles of self-organization, and the hybrid approach which combine the best of the emergent systems and cognitivist systems. Our research focuses on implementing a hybrid architecture for cognitive agents supported by both cognitivist and emergent approaches. On the one hand, the cognitivist approach provides an explicit knowledge representation through the use of symbolic AI techniques. On the other hand, the emergent approach defines three evolutionary strategies as observed in nature: Epigenesis, Ontogenesis, and Phylogenesis, endowing the architecture with implicit knowledge learning, sub-symbolic representations, and emergent behavior guided by bio-inspired computational intelligence techniques.

Imagen de apoyo de Implementing value engineering studies in public infrastructure project delivery framework

Por: Felipe Castro Arenas | Fecha: 2013

Some authors argue that Value Engineering (VE) is just an audit exercise carried out over the work of planners and designers, and that the large success it has had in organizations like the Federal Highway Administration (FHWA) in the USA is just a proof that engineers are doing things wrong from the outset (Winch, 2002). In many cases, VE studies are executed just in a reactive manner when project managers face budget overruns and schedule delays. However, VE has shown ever more effective when it is fully integrated into the organization’s project delivery framework. Nonetheless, deciding upon the best timing for executing VE studies still remains controversial. The timing is a critical factor for the effectiveness of VE studies and this article attempts to shed light on this issue
