New computational tools for chemical kinetics: the Cathedral Package
The advent of recent technological developments in software engineering has enabled the exploration of reaction mechanisms inside intricate reaction networks, thereby propelling the beginning of a new era in ab initio kinetics. While it is feasible to consider a substantial number of reactions, determining their rate constants with precision remains an arduous task, even for gas-phase processes. The difficulties are attributed not only to the inherent limitations in the calculation methodology but also to the manual labor and extensive chemical dynamics required, rendering these calculations inaccessible to the general public. As such, there is a pressing need for the development of automated codes and user-friendly interfaces to address this limitation. The present work focuses on the introduction of the Cathedral package, a unified computational code comprising the Q2DTor, TorsiFlex, and Pilgrim programs. This package serves to bridge the gap between theoretical studies in chemical kinetics and non-specialist users, making it more accessible and user-friendlyThe authors thank “Centro de Supercomputación de Galicia” (CESGA) for the use of their computational facilities.

Conceptions of Contemporary Art in the school culture and integration possibilities. A case study
Presentamos una experiencia que se ha desarrollado en el marco del Máster Universitario
en Profesorado en Enseñanza Secundaria Obligatoria y Bachillerato, Formación
Profesional y Enseñanzas de Idiomas (MAES), de la Universidad de Sevilla. En concreto
se trata del diseño y experimentación de un proyecto de innovación que
toma la forma de una secuencia de actividades para ser experimentada durante el periodo
de prácticas con un grupo de alumnos de 4º de ESO de un IES de la ciudad de Sevilla.
Supone, además, una experiencia personal de reflexión sobre las posibilidades del Arte
Contemporáneo como guía e instrumento didáctico para la enseñanza de las Ciencias
Sociales, el cual conecta con la cultura eminentemente visual que nos define actualmenteWe present an experience which has been developed in the framework of the Master of
secondary teacher training at the University of Seville. Specifically, it is the design and
testing of an innovation project that takes the form of a sequence of activities to be
experienced during the practice with a group of students from a High School course in
Seville. It also assumes a personal experience of reflection on the possibilities for the
teaching of Social Sciences, using a learning resource, contemporary art, as a guide and
pedagogical resource which connects with the predominantly visual culture in the world

Evaluation of nature inspired metaheuristics for search and reconnaissance operations by rotary-wing aircrafts / Avaliação de meta heurísticas inspiradas na natureza para operações de busca e reconhecimento por aeronaves de asa móvel
The main objective of this work is the evaluation of two nature in-spired meta-heuristics, Genetic Algorithms and Ant Colony, for the development of an application that can generate optimized routes for aircraft, attending the requirements of the Brazilian Navy. This work presents the methods developed, complying with two main constraints: checkpoints mobility and limited aircraft autonomy. It also presents the results of tests performed with the methods developed and an evaluation of their performances.
Smart Devices and Services for Smart City
Citizen quality of life can be improved through facilities and services that have been thought to ease citizen interaction with municipal authorities, offices and structures. All technologies and devices, used for developing these facilities, are the pillars of the Smart City idea: a City that adapts itself, at least in part, to citizens’ needs. Advanced Metering Infrastructure (AMI) could become the backbone of all the smart city projects. Other public services can be loaded on AMI’s to be smart and thus helping to find the affordability of investments. The paper deals with this topic by describing devices and results of a pilot project, which has been carried out in an Italian middle city (Salerno), to experience the use of RF 169MHz wM-bus based AMI. Experimental results regarding a set of about 2500 installed devices for gas and water metering, car parking management and elder tele-assistance, will be reported in detail to show convenience and problems of this approach
