Human-agent societies refer to applications where virtual agents and humans coexist and interact transparently into a fully integrated environment. One of the most important aspects in this kind of applications is including emotional states of the agents(humans or not) in the decision-making process. In this sense, this paper presents the applicability of the JaCalIVE(Jason Cartago implemented intelligent virtual environment) framework for developing this kind of society. Specifically, the paper presents an ambient intelligence application where humans are immersed into a system that extracts and analyzes the emotional state of a human group. A social emotional model is employed to try to maximize the welfare of those humans by playing the most appropriate music in every moment.

In Mexico, owing to solar radiation conditions, there is great potential for PV （photovoltaic） systems. Besides, since 2007, the solar electricity interconnection agreement became official which allowed for an important growth of the photovoltaic industry. Due to the important development of the PV industry, there is a need for engineers trained to design, install, and evaluate PV systems The UAEMEX （autonomous university of the state of Mexico） offers a new bachelor degree of engineering program which dedicated to the development of sustainable energy systems. This kind of programs requires special equipment for experimentation and practice Specialists at UAEMEX also detected the need for a system to evaluate and demonstrate the application of PV modules, but they also found that most of the systems on the market are very expensive and unable to evaluate different arrangements. The goal of this paper is to present the design of a mobile system to evaluate PV modules and arrangements. This system is useful, not only for demonstration practices, but also for experimentation with different materials and types of PV panels. The design allows for two or four PV modules to be assembled in different positions and inclinations. The prototype is equipped with a data acquisition system that will be used to obtain the PV module performance curves. It will also be used to evaluate the atmospheric, interference and shadow effects on these modules. This prototype will be used to complement the practice learning of solar PV systems, but also to demonstrate the use of PV modules. The prototype is being design and constructed by a group of mechanical and electronic engineering students and this fact will be useful to meet the needs of basic science, math, and engineering teaching objectives in an integrated and hands-on way project. The essential features of system are described. A comparative analysis of the systems on the market is carried out. Also presented are the learning adv

The addition of Au3. to spherical amine-capped CdSe@ZnS nanoparticles in toluene at room temperature and under darkness can lead to ternary CdSe@ZnS/Au nanohybrids. We demonstrate that this happens only when the nanoparticles possess a relatively thin ZnS shell, thus showing that thickness plays a key role in gold deposition on the CdSe@ZnS nanoparticle surface. Our hypothesis is that the amine ligand acts as the reductant of Au3＋ ions into Au＋ ions, whose affinity for sulfur would keep them at the CdSe@ZnS surface. This interaction stabilizes the Au＋ ion, making it less prone to reduction than a non-coordinated Au＋ ion. In CdSe@ZnS with a thin shell, Au＋ ions at the surface of, or most probably within, the ZnS shell cause the transfer of Cd2＋ ions into the solution. Subsequently, the core Se2- anion, which is a better reductant than the shell S2- reduces Au＋ ions to Au（0）, and large gold nanoparticles （AuNPs） are quickly deposited on the CdSe@ZnS surface in room temperature process, leading to ternary CdSe@ZnS/Au nanohybrids. In solution, these ternary nanohybrids progressively transform into quaternary CdSe@ZnS/Au2S/Au nanohybrids due to the reaction of the shell S2- anion with the remaining Au＋ at the CdSe@ZnS surface, thus leading to the growth of Au2S nanoparticles on the CdSe@ZnS surface while Zn concomitantly leaches from the nanohybrid into the solution. Photoirradiation of the heterostructures with visible light enhances their emission efficiency. Comparatively, irradiation of the precursors, i.e., CdSe@ZnS nanoparticles, causes a drastic decrease in their emission accompanied by a blue shift of their emission maximum. The optical properties of these nanohybrids were analyzed by absorption and fluorescence （steady-state and time-resolved） spectroscopy, and the composition of the samples and the chemical states were determined by energy dispersive X-ray spectroscopy （EDX） and X-ray photoelectron spectroscopy （XPS）, respectively. Finally, the structural and m
