web information extraction based on Template flow Configuration
Computer Engineering, 2008Co-Authors: X U XuezhouAbstract:To solve the existing problems such as the complexity to constructing wrappers and extracting precision,a Web extraction framework based on Template flow Configuration is presented and accomplished.Decompose the actions of requiring,accessing and obtaining of users,and extract those action patterns,reflecting them into the flow Configuration Template as nodes.Flow interpreter will interpret the flow Configuration description XML document which is created by users,and then extract the information which is interesting to them.Experimental result indicates that the framework can quickly and correctly realize the extraction.

Designing option FTRs for the lossy FTR system
Iet Generation Transmission & Distribution, 2018Co-Authors: Shri Ram Vaishya, Vaskar SarkarAbstract:The objective of this study is to upgrade the lossy financial transmission right (FTR) mechanism through the introduction of lossy option FTRs. The lossy FTR mechanism retains the potential to deliver superior risk hedging performance compared with the traditionally deployed lossless FTR mechanism since the locational marginal price decomposition is unnecessary for the settlement of lossy FTRs. The existing lossy FTR theory is, however, based on only obligation FTRs. Although obligation FTRs are the primary risk hedging instruments under any FTR mechanism, option FTRs can improve market competition by allowing flexible hedge positions. Therefore, an investigation is carried out to explore a lossy version of option FTRs. The Configuration Template and the settlement rule for lossy option FTRs are established. A suitable auction model is prepared for the issuance of lossy option FTRs. The lossy FTR auction formulation is carried out based on a novel representation of power flow equations. Detailed case studies are presented to show the practical utility of the proposed lossy FTR instrument.

knowledge Configuration model for fast derivation design of electronic equipment and its implementation
Knowledge Based Systems, 2020Co-Authors: Jun Peng, Meng Wang, Yuegang Song, Xijia QinAbstract:Abstract There has contradictions in timeliness and diversity in the design schemes of complex product systems. The traditional solidified knowledge Template for the knowledge reuse purpose cannot meet the rapid design needs of complex products. This paper proposes a configurable knowledge ontology model (CKOM) and a corresponding design method for rapid derivation of complex products. Based on the combination of basic knowledge elements (BKE), customized knowledge elements (CKE), and assorted knowledge elements (AKE), a knowledge structural body (KSB) is constructed by unitizing knowledge ontology into units of knowledge. And a dynamic structured knowledge Template Configuration method based on physical form (Pf) Configuration and virtual form (Vf) association is proposed. The knowledge Configuration information is transmitted and parsed in XML form, and the virtual form is established to associate and dynamically configure the corresponding physical form knowledge structure. Based on the structured knowledge model Configuration Template, a rapid derivative design method for electronic equipment is proposed. The rapid derivation design process is divided into three stages: requirement analysis, index demonstration, and scheme formation. By establishing seven knowledge attributes, such as global, local, scope, retrieval, the required product knowledge elements, rule knowledge elements and tools are dynamically configured to realize the dynamic processing of design parameters based on Configuration knowledge elements and then form a corresponding design scheme. Finally, a rapid derivation design system is developed and applied to electronic equipment, which verifies the rationality and effectiveness of the proposed model and method.

Pruebas de Habilidades
2020Co-Authors: Cardona Zapata, Mauricio AlbertoAbstract:Por medio del diplomado de profundización Cisco CCNA, pretendemos lograr obtener una de las certificaciones más importantes dentro de la industria de la Tecnología de la Información. Esta certificación representa el nivel asociado, orientada a habilidades prácticas en el diagnóstico y solución de problemas específicos de redes. Para ello debemos diseñar una plantilla de configuración para administrar, configurar e interconectar la red de las sucursales de una empresa de Tecnología ubicadas en las ciudades de Bogotá, Medellín y Bucaramanga, para esto usamos la herramienta Packet Tracer, que es una herramienta de aprendizaje y simulación de redes interactiva para instructores y alumnos de Cisco CCNA. Esta herramienta nos permite crear topologías de red, configurar dispositivos, insertar paquetes y simular una red con múltiples representaciones visuales.Through the Cisco CCNA Diploma of Deepening, we aim to achieve one of the most important certifications within the Information Technology industry. This certification represents the associated level, oriented to practical skills in the diagnosis and solution of specific network problems For this we must design a Configuration Template to manage, configure and interconnect the network of branches of a Technology company located in the cities of Bogotá, Medellin and Bucaramanga, for this we use the Packet Tracer tool, which is a learning tool and interactive and networking simulation for Cisco CCNA instructors and students. This tool allows us to create network topologies, configure devices, insert packets and simulate a network with multiple visual representations
