Cargador fotovoltaico para Smartphones de última generación.

[ES]Este proyecto tiene como objetivo diseñar e implementar un prototipo de un cargador fotovoltaico para teléfonos móviles de última generación. Dicho prototipo constará de un panel fotovoltaico, reguladores de tensión y corriente, un MPPT, un regulador de carga de batería, una batería auxiliar y una conexión USB para conectarlo al dispositivo a cargar. Para su realización, se llevará a cabo un estudio previo para obtener conocimientos sobre el funcionamiento de las nuevas tecnologías en esta área, su oferta en el mercado, y se hará uso de las herramientas necesarias para su diseño, implementación y pruebas posteriores.

Desarrollo e implementación de un relay de mensajería para la aplicación Kde-Connect.

[EN]Nowadays, with the unstoppable raise of different types of electronic devices (mobile phones, tablets, computers…), it has become a necessity to share all the information and functionalities they have. In order to achieve that, back in the 2013, KDE community developed an application called KDE-Connect. This application has been really useful since then, but it’s limited as it can only operate with devices in the same network. Therefore, in the following pages, this project will explain and develop the best solution to extend its functionalities so any pair of devices can share information in an anonymous, private and easy way, at any geographic location.

Impact of Cyberprogram 2.0 on Different Types of School Violence and Aggressiveness

Some antibullying interventions have shown positive outcomes with regard to reducing violence. The aim of the study was to experimentally assess the effects on school violence and aggressiveness of a program to prevent and reduce cyberbullying. The sample was comprised of a randomly selected sample of 176 adolescents (93 experimental, 83 control), aged 13-15 years. The study used a repeated measures pre-posttest design with a control group. Before and after the program, two assessment instruments were administered: the "Cuestionario de Violencia Escolar-Revisado" (CUVE-R [School Violence Questionnaire- Revised]; Alvarez Garcia et al., 2011) and the "Cuestionario de agresividad premeditada e impulsiva" (CAPI-A [Premeditated and Impulsive Aggressiveness Questionnaire]; Andreu, 2010). The intervention consisted of 19 one-hour sessions carried out during the school term. The program contains 25 activities with the following objectives: (1) to identify and conceptualize bullying/cyberbullying; (2) to analyze the consequences of bullying/cyberbullying, promoting participants' capacity to report such actions when they are discovered; (3) to develop coping strategies to prevent and reduce bullying/cyberbullying; and (4) to achieve other transversal goals, such as developing positive variables (empathy, active listening, social skills, constructive conflict resolution, etc.). The pre-posttest ANCOVAs confirmed that the program stimulated a decrease in: (1) diverse types of school violence teachers' violence toward students (ridiculing or publicly humiliating students in front of the class, etc.); students' physical violence (fights, blows, shoves... aimed at the victim, or at his or her property, etc.); students' verbal violence (using offensive language, cruel, embarrassing, or insulting words... toward classmates and teachers); social exclusion (rejection or exclusion of a person or group, etc.), and violence through Information and Communication Technologies (ICT; violent behaviors by means of electronic instruments such as mobile phones and the Internet); and (2) premeditated and impulsive aggressiveness. Pre-posttest MANCOVA revealed differences between conditions with a medium effect size. This work contributes an efficacious intervention tool for the prevention and reduction of peer violence. The conclusions drawn from this study have interesting implications for educational and clinical intervention.
