The problem of architectural heritage conservation in a consolidated historic urban context is worldwide relevance. In Ecuador, and specifically Cuenca, there are no specific approaches to evaluate the environmental impact on deterioration, therefore, an alternative diagnostic travertine facades proposed define levels deterioration based climatic factors through case study. Two research stages developed; 1) preliminary diagnosis architectural, anthropic components, using cards Leopold’s...

This paper presents a method for assess the risk index in power transformers park, is metric that allows park administrator to ensure an optimal physical asset management, allocating properly financial and human resources operation maintenance actions. Assessing requires calculating two secondary sub-index termed failure probability consequence factor. Those indexes are integrated into value. In order illustrate this process, 16 units evaluated, those operates national Ecuadorian electric...

The design of a distal extremity prosthesis (right hand) based on the anthropometric measures 10-year old child is presented. Each finger disposed in two sections, fusion middle and phalanx, proximal phalanx articulated to hand palm. angles movement for extension flexion all fingers, except thumb, are controlled by link located sideways. drive system, that generates three degrees freedom execute cylindrical grasp's functions, precision grasp, hook prehension extended index finger, linear...

This paper describes the performance of a PVT solar collector in thermosyphon closed loop mode. The electrical and thermal were evaluated compared with same unmodified factory PV panel. was by electrical, primary energy savings efficiencies. It found that power enhanced 1.56%, also potential 10.73% achieved, finally saving 28.14%.

Consistency of Bayes procedures on the sphere is studied. Equivalent conditions for consistency a rotationally symmetric model are given. that an antipodally also provided.

In the present article a design of photovoltaic solar system will be made for electric power supply in 790 GAD's Parish facilities Ecuador, designed start working when local GAD requires it without connection to public network or by unforeseen cuts power, situation that is very recurrent rural areas Ecuador and through this continuity service inhabitants corresponding jurisdiction guaranteed. It interesting purpose since National Government should promote type initiatives medium term, due...

In a globalized, demanding, and virtualized environment, uncertainty is part of the academic performance. This condition affects all schools irrespective education level, size, or location, therefore tendency to suffer consequences volatility phenomena, including change rate in methodological strategies. present work, factors that motivate exposure higher centres are identified, using model based on principles fuzzy diffuse subsets, called Forgotten (fuzzy) Effects. methodology has allowed...

Having digital resources for inclusive education is one of the challenges faced by teachers and institutions. This systematic review focuses on finding developments in educational oriented towards teaching mathematics. Studies Spanish English from 2018 to 2022 were considered searching Scopus, Web Science, ERIC, IEEE, PsycINFO databases. The work was carried out following PRISMA statement (Ouzzani et al., 2016; Page 2021), steps proposed Sánchez-Meca (2022), recommendations Marín (2022)....

High concentrator photovoltaic systems look for a remarkable reduction of cost in the production electricity from solar radiation. This is possible thanks to an optical system which focus light on small cell. In this manner, high semiconductor material substituted by potentially lower system. Since that, kind modules, efficiency optics achieves similar importance than cell itself. On other hand actually obtain desired reduction, new elements and process needed must be low. The purpose work...

Due to the great growth of alternative energies, as a means mitigate high polluting emissions in environment. It has been convenient monitor solar parameters through SCADA system developed Matlab and data acquisition card such Arduino, visualize real time variations that panel 24 hours day between its voltage levels, current delivered power, generating this way contribution reduces cost equipment used for these new technologies, making it much more accessible users who previously could not...

Este documento presenta una propuesta de configuracion un chatbot en la aplicacion Telegram, empleando herramienta NodeRed con el objetivo que los usuarios (gobierno, instituciones salud publica y privada, personas general) consulten estadisticas, por provincia del Ecuador, sobre pandemia mundial COVID-19. La idea principal es determinar utilidad este tipo aplicaciones basadas IoT bajo metodologia experimental, para obtener datos numero casos contagio, recuperados, fallecidos descartados,...

We present a new optical current sensor architecture, which is based on polarimetric configuration and control system for self-compensation of the Faraday effect taking place at head. After passing through bulk head, light travels free space reaching modulator placed some distance away from conductor carrying current. The first device acts transducer second one as magneto-optical element operated in closed-loop mode to compensate angle rotation polarization introduced by operates closed loop...
