Single Objective

When making statistical analysis of single-objective optimization algorithms’ performance, researchers usually estimate it according to the obtained optimization results in the form of minimal/maximal values. Though this is a good indicator about the performance of the algorithm, it does not provide any information about the reasons why it happens. One possibility to get additional information about the performance of the algorithms is to study their exploration and exploitation abilities. In this paper, we present an easy-to-use step by step pipeline that can be used for performing exploration and exploitation analysis of single-objective optimization algorithms. The pipeline is based on a web-service-based e-Learning tool called DSCTool, which can be used for making statistical analysis not only with regard to the obtained solution values but also with regard to the distribution of the solutions in the search space. Its usage does not require any special statistic knowledge from the user. The gained knowledge from such analysis can be used to better understand algorithm’s performance when compared to other algorithms or while performing hyperparameter tuning.

Service Paradigm

As many software systems migrate their component communication to the web service paradigm, security becomes an immediate concern. Many existing solutions cannot handle complex situations involving the user, session, application, and any number of XML inter-related documents. The learner information management web service we develop for an e-learning environment has to control access of inter-related XML documents representing different roles of users in the e-learning environment. In this paper, we present an authentication and authorization model for web services that provides access control of inter-related XML documents. This scheme works especially well when the documents that will be operated on are organized in hierarchical structures, like the collections in a native XML database.

E Learning

Data Mining and Data Warehousing are two most important techniques for pattern discovery and centralized data management in today’s technology. ELearning is one of the most significant applications of data mining. The main objective is to provide a proposal for a functional model and service architecture. The standards and system architecture are analyzed here. This paper gives importance to the integration of Web Services on the e-Learning application domain, because Web Service is the most advanced choice for distance education now. The process of e-Learning can be possible more effectively with the help of Web usage mining. More advanced tools are developed for online customer’s behaviour to increase sales, and profit, but no such tools are developed to understand learner’s behaviour in e-Learning. In this paper, some data mining techniques are discussed that could be used to enhance web-based learning environments.

In this chapter the authors present E-World, an e-learning platform able to manage and trace adaptive learning processes which are designed and created by means of a visual language based tool. To address the goal to have a platform easily extensible with new services, they have designed it selecting a software architecture based on the use of Web Services and a suitable Middleware component. To trace adaptive learning processes E-World also integrates as Web Service a suitable implementation of a Run- Time Environment compliant with the Sharable Content Object Reference Model (SCORM) standard. Their proposal also supports the “anytime and anywhere” learning paradigm as it enables learners to enjoy linear or adaptive processes using any device equipped with a standard Web browser. In the chapter they also report on the experiment we have carried out to assess the usability of the proposed e-learning platform.

Las técnicas de e-learning han mejorado el rendimiento en el sistema educativo moderno. Falta un sistema degestión de e-learning efectivo y de bajo costo, y las herramientas podría tener un impacto negativo en elrendimiento educativo. La incorporación de tecnologías en línea en el proceso de aprendizaje puede cubriresta desventaja. El sistema de nube de Amazon Web Service es una de las últimas tecnologías que ofrecengrandes volúmenes de servicios en las plataformas de aprendizaje electrónico. Accesando la capa gratuita deAWS, el sistema de gestión de aprendizaje (un Moodle con MYSQL), el alojamiento de archivos y losservicios de gestión de contenido se consideran herramientas complementarias que son viables mediante eluso de la plataforma AWS. Una explicación concisa relacionada con el diseño de la metodología se presentaen el documento junto con las ventajas del sistema que se detallan en la sección de conclusión. A pesar de quetodavía existen varios riesgos asociados con la implantación de la nube, debido a las potenciales ventajas,como el costo bajo o gratuito, el alto rendimiento en tiempo real y el diseño seguro superan los riesgos ydesafíos.
