The term refers to physical spaces incorporating pervasive computing technology used to achieve specific goals for the user, the environment or both. This book presents the proceedings of the workshops of the 9th International Conference on Intelligent Environments (IE 13), held in Athens, Greece, in July 2013. The workshops which were presented in the context of this conference range from regular lectures to practical sessions. They provide a forum for scientists, researchers and engineers from both industry and academia to engage in discussions on newly emerging or rapidly evolving topics in the field. Topics covered in the workshops include artificial intelligence techniques for ambient intelligence; applications of affective computing in intelligent environments; smart offices and other workplaces; intelligent environment technology in education for creative learning; museums as intelligent environments; the application of intelligent environment technologies in the urban context for creating more sociable, intelligent cities and for constructing urban intelligence. IE can enrich user experience, better manage the environments resources, and increase user awareness of that environment. This book will be of interest to all those whose work involves the application of intelligent environments.

This set obtained generate the most common seven-frame algorithms in the state of art. The algorithms are analized for the compensation of common errors such as phase shifthing, phase errors because variation of light or bias. Fringe analysis, Phase-shifting interferometry, Softcomputing Resumen En este artículo se presenta una familia de algoritmos de siete cuadros para la perfilometria de desplazamiento de fase y su aplicación para la obtención de perfiles tridimensionales usando cómputo suave. Esta familia obtenida genera la mayoría de los algoritmos de siete cuadros más comunes en el estado del arte. Los algoritmos son analizados en la compensación de errores comunes como el desentonamiento de fase, errores de fase debido a la variación de iluminación o bias.

This paper suggests the development of an intelligent Internet of Things based system with the use of meta-heuristics that will be able to find optimal energy saving configurations. This system takes into account the activity of the users, size of area, state of lights, and blinds. A comparative study of four optimization techniques (GA, PSO, DBDE, and BSO) with the use of the Friedman test is shown.

La captura de las señales de vibración de vibración se realiza usando un acelerómetro de una pulsera bluetooth. El procesamiento de las señales de vibración se realiza procesando el valor rms y valores pico de las señales de los pacientes. Finalmente se utilizan diferentes clasificadores para evaluar el grado de afectación de la vibración en pacientes con Parkinson.

Intelligent systems have been reported to offer comfort to a single user or averaging the comfort of multiple users without considering that their needs may be different from those of other users. This work defines a versatile model for a multi-user intelligent system that negotiates with the resources of the environment to offer visual comfort to multiple users with different profiles, activities and priorities using soft-computing algorithms. In addition, this model makes use of external lighting to provide the recommended amount of illumination for each user without having to totally depend on artificial lighting, inducing there will be an energy efficiency but without measuring it.

Based on the structure with multiple layers, subsystems and varied topologies that in previous research have shown that fuzzy hierarchical systems have been used to improve the interpretability, in this research work the objective is to design a fuzzy hierarchical system using fuzzy composite concepts artificial intelligence compounds to measure the efficiency of simulated scenarios. As a fundamental part of the present investigation, an analysis is made of the sensitivity of the results of the fuzzy system with respect to its inputs and with a set of membership functions, in a virtual scenario; which allows demonstrating the advantages obtained by applying a fuzzy hierarchical system to systems oriented to the area of health.

It is important to consider that the technology must be friendly with users, and even adapt to their needs and desires [1]. In this research, we present the physical implementation of a general system to assist users and patients in daily activities or duties. The system was implemented in a room and include sensors, actuators and wireless agents. This research is focused on people with some movement restrictions. The results are very promising, the user was successfully able to move several elements in the room (like windows or blinds) using only a mobile device as a tablet or a smart phone. Additionally, in order to see his potential adaptation and versatility, several devices where connected successfully to give comfort to the users.

That is why the use of optimization algorithms has been made necessary in everyday life. This paper presents a comparison study between micro-algorithms: Genetic Algorithm (GA), Artificial Immune System (AIS), Estimation Distribution Algorithm (EDA), Particle Swarm Optimization(PSO), Bee Algorithm (BA) and Bee SwarmOptimization (BSO). To perform an activity in a confined space, this is affected by the light from the outside, which can be blocked by shutters and doors (of crystal), and lighting of lamps obtained within this space. It is then necessary to obtain the best combination using any optimization algorithm on the condition that it should be each of these objects to have a lighting comfort.

The Lagrangian function of the standard Support Vector Machine in its dual form was considered to derive the proof. Results of this derivation allow researchers to properly justify the use of approximate methods, such as heuristics and metaheuristics, when working with multiple kernel learning algorithms.
