Propuesta de integración de agentes software inteligentes sobre JADE con entornos virtuales en Unity3D

La unión de distintos sistemas software constituye un elemento principal de las nuevas Tecnologías de la Información y la Comunicación. La integración de entornos virtuales tridimensionales con agentes software inteligentes es el objetivo que persigue este trabajo de investigación. Para llevar a cabo esta integración se parte de la creación de un agente virtual, un personaje que es controlado por una mente desarrollada siguiendo un enfoque basado en agentes software. Se busca así dotar al sistema de cierto nivel de inteligencia, tomando como referencia el funcionamiento del cerebro humano. Lo que se consigue es que el agente capte los estímulos del entorno, los procese y genere comportamientos, tanto reactivos como deliberativos, que son ejecutados por el personaje. Los resultados obtenidos resaltan el dinamismo del sistema, a la vez que animan a seguir investigando en este campo lleno de aplicaciones directas y reales sobre el mundo. En conclusión, esta investigación busca y consigue un nuevo paso en el progreso de las nuevas tecnologías mediante una integración real de distintos sistemas software. ---ABSTRACT---The union of different software systems is a major element of Information and Communications Technology. The aim of this research is the integration of 3D virtual environments and intelligent software agents. This integration is based on the development of a virtual agent, a character that is controlled by a mind developed following a software agent approach. It is sought to provide the system with some intelligence level, taking the human brain function as a reference point. The consequence is that the agent captures environmental stimuli, processes them and creates reactive and deliberative behaviours that can be executed by the avatar. The findings emphasize the dynamism of the system as well as they encourage to research more in this field that has a lot of direct and real-life applications on the world. In conclusion, this research seeks and takes a new step in the progress of new technologies through a real integration of different software systems.

Application of Independent Components Analysis with the JADE algorithm and NIR hyperspectral imaging for revealing food adulteration

In recent years, Independent Components Analysis (ICA) has proven itself to be a powerful signal-processing technique for solving the Blind-Source Separation (BSS) problems in different scientific domains. In the present work, an application of ICA for processing NIR hyperspectral images to detect traces of peanut in wheat flour is presented. Processing was performed without a priori knowledge of the chemical composition of the two food materials. The aim was to extract the source signals of the different chemical components from the initial data set and to use them in order to determine the distribution of peanut traces in the hyperspectral images. To determine the optimal number of independent component to be extracted, the Random ICA by blocks method was used. This method is based on the repeated calculation of several models using an increasing number of independent components after randomly segmenting the matrix data into two blocks and then calculating the correlations between the signals extracted from the two blocks. The extracted ICA signals were interpreted and their ability to classify peanut and wheat flour was studied. Finally, all the extracted ICs were used to construct a single synthetic signal that could be used directly with the hyperspectral images to enhance the contrast between the peanut and the wheat flours in a real multi-use industrial environment. Furthermore, feature extraction methods (connected components labelling algorithm followed by flood fill method to extract object contours) were applied in order to target the spatial location of the presence of peanut traces. A good visualization of the distributions of peanut traces was thus obtained
