This study is aimed to prove how Virtual Environments (VE) and Information and Communication Technologies (ICT) can be used as a tool to verify professional competencies. The incursion of virtual environments in education has shown that there is much potential in distance learning development. To find out how it influences the achievement of competencies, there was made an experimental study with a post-test design and control group. Students were divided into two groups; each of them was submitted to a different test. The results demonstrate that with the implementation of VE using ICT, the students who used the VE had a better performance than students who used the traditional evaluations. Confirmed with the 83% of the sample who achieved the highest levels (50% got strategical professional competencies, and 33% got autonomous professional competencies). Considering the study, the authors could notice that students do develop professional competencies along virtual environments, reflected not only in the level of competence achieved by the ones tested on the virtual environment but also in the average time they spend to do the test. Therefore, virtual environments have positives effects in the education field.

El componente práctico es realmente importante en el proceso de enseñanza aprendizaje debido a que este permite que los fundamentos teóricos se afiancen logrando así la aprehensión de los conocimientos en cualquier área del saber. Uno de los elementos de la educación que más aporta al mencionado componente práctico son los laboratorios, el cual visto desde la óptica de la literatura de los años anteriores a los 90’s y del sentido común, se define como un espacio o lugar físico el cual está equipado de dispositivos, instrumentos y elementos de medición donde se desarrollan actividades académicas y/o de investigación, pudiéndose o no acondicionar características de un entorno real de acuerdo al tipo de experimentación. Este tipo de laboratorio en la actualidad es llamado Laboratorios Tradicionales (LT). Hoy en día, en la era digital en que la información es casi ubicua, donde los escenarios formativos que hacen uso de las TIC1 han ido en aumento y las IES2 que las han incorporados en sus proyectos, políticas, metas y estrategias institucionales, se hace importante la implementación de laboratorios remotos favoreciendo el establecimiento de horarios flexibles e ingresos desde cualquier lugar y en cualquier momento para la realización de prácticas.

Cross-Evaluation of Reflectivity from NEXRAD and Global Precipitation Mission during Extreme Weather Events
...
Acosta-Coll, Melisa | 2022-08-02

During extreme events such as tropical cyclones, the precision of sensors used to sample the meteorological data is vital to feed weather and climate models for storm path forecasting, quantitative precipitation estimation, and other atmospheric parameters. For this reason, periodic data comparison between several sensors used to monitor these phenomena such as ground-based and satellite instruments, must maintain a high degree of correlation in order to issue alerts with an accuracy that allows for timely decision making. This study presents a cross-evaluation of the radar reflectivity from the dual-frequency precipitation radar (DPR) onboard the Global Precipitation Measurement Mission (GPM) and the U.S. National Weather Service (NWS) Next-Generation Radar (NEXRAD) ground-based instrument located in the Caribbean island of Puerto Rico, USA, to determine the correlation degree between these two sensors' measurements during extreme weather events and normal precipitation events during 2015-2019. GPM at Ku-band and Ka-band and NEXRAD at S-band overlapping scanning regions data of normal precipitation events during 2015-2019, and the spiral rain bands of four extreme weather events, Irma (Category 5 Hurricane), Beryl (Tropical Storm), Dorian (Category 1 hurricane), and Karen (Tropical Storm), were processed using the GPM Ground Validation System (GVS). In both cases, data were classified and analyzed statistically, paying particular attention to variables such as elevation angle mode and precipitation type (stratiform and convective). Given that ground-based radar (GR) has better spatial and temporal resolution, the NEXRAD was used as ground-truth. The results revealed that the correlation coefficient between the data of both instruments during the analyzed extreme weather events was moderate to low; for normal precipitation events, the correlation is lower than that of studies that compared GPM and NEXRAD reflectivity located in other regions of the USA. Only Tropical Storm Karen obtained similar results to other comparative studies in terms of the correlation coefficient. Furthermore, the GR elevation angle and precipitation type have a substantial impact on how well the rain reflectivity correlates between the two sensors. It was found that the Ku-band channel possesses the least bias and variability when compared to the NEXRAD instrument's reflectivity and should therefore be considered more reliable for future tropical storm tracking and tropical region precipitation estimates in regions with no NEXRAD coverage.

Forecasting and communication key elements for low-cost fluvial flooding early warning system in urban areas
...
Acosta-Coll, Melisa | 2021

Fluvial flooding occurs when a river overspills its banks due to excessive rainfall, and it is the most common flood event. In urban areas, the increment of urbanization makes communities more susceptible to fluvial flooding since the excess of impervious surfaces reduced the natural permeable areas. As flood prevention strategies, early warning systems (EWS) are used to reduce damage and protect people, but key elements need to be selected. This manuscript proposes the monitoring instruments, communication protocols, and media to forecast and disseminate EWS alerts efficiently during fluvial floods in urban areas. First, we conducted a systematic review of different EWS architectures for fluvial floods in urban areas and identified that not all projects monitor the most important variables related to the formation of fluvial floods and most use communication protocols with high-energy consumption.ZigBee and LoRaWAN are the communication protocols with lower power consumption from the review, and to determine which technology has better performance in urban areas, two wireless sensor networks were deployed and simulated in two urban areas susceptible to fluvial floods using Radio Mobile software. The results showed that although Zigbee technology has better-received signal strength, the difference with LoRAWAN is lower than 2dBm, but LoRaWAN has a better signal-to-noise ratio, power consumption, coverage, and deployment cost.

Museums play an important role in preserving the heritage and cultural legacy of humanity, however, one of their main weaknesses in regards the user is their static nature. At present, and in the face of the development of diverse technologies and the ease of access to information, museums have upgraded their implementation of technologies aimed at improving the user experience, trying more and more to access younger audiences with a sensitivity and natural capacity for the management of new technologies. This work identifies trends in the use of technological tools by museums worldwide and the effect of these on the user or visitor experience through a review of scientific literature. To complete the work, we performed a search of the publications in the Scopus® referencing database, and downloaded, processed, and visualized the data using the VOSviewer® tool. The main trends identified in this context of analysis are related to the role of museums with the development and improvement of the user experience; orientation to young audiences and innovation driven by the user through Interactive Systems, digital games, QR Codes, apps, augmented reality, virtual reality and gamification, among others. The objective of the implementation of new technologies in the context of museums is to satisfy the needs of contemporary communication, for all types of content and aimed at an increasingly digital audience, in order to ensure positive interaction and feedback from ideas with social and cultural changes.

Acosta-Coll, Melisa | 2021-09-13

Currently, people want to take control of what they consume as well as the local authorities pursue to implement measures to improve sustainability, food security, and living standards. Indoor urban farming initiatives provide an opportunity to grow their own and obtain fresher food with fewer transportation emissions, likewise, it is a strategy to lift people out of food poverty, reduce environmental impact since the use of herbicides and pesticides is minimal and helps to reduce food waste. However, factors such as the time dedicated to the cultivation of plants, and the adequate space inside their houses prevents them from carrying out this activity. This project presents the design of a low cost smart indoor greenhouse design to cultivate herbs and vegetables with minimum human intervention monitored by a web application. The prototype has three systems to control and monitor the main variables involved in the plant’s growth such as soil moisture, temperature, and solar light intensity. Likewise, it is suitable for a home with little space and it is easily installable, has low energy consumption, and is cost-efficient. © 2021, Springer Nature Switzerland AG.

Castro, Adalberto Ospino | 2021

This Article submits a review of the integration of renewable energies in the contemporary distribution of generated energy. A technological supervision is implemented to observe in a systematic manner the behavior of state of the art technologies in renewable energies, in the search of energetic sustainability, making an analysis of the distribution of the most representative Microgrids at world level. It is to be noted, the great inclusion of energy obtained through solar panels, and Eolic generators. However, there is a great participation of generators from diesel vapor, and gas; while in the storage system batteries are predominant, and sometimes, flywheels and supercapacitors surface. These results are possibly due to the promotion and experience of including new techniques and use of energy resource methodologies

Substrate treatment for the increment of electric power potential from plants microbial fuel cells
...
Acosta-Coll, Melisa | 2021

Plants microbial fuel cells (PMFC) is novel systemthat generates renewable, clean, and sustainable electricity with minimal environmentalimpact. However, PMFC has limitations in power generation and current density, since its production values is lower than other renewable technologies. Different studies show that the highest limitation for energy generation through MFC is the high resistivity of the cathode, and the solution is to replace the metallic electrodes with non-metallic materials to obtain a better performance, however, the application of these materials requires complex interdisciplinary work. This study conducted three experimental tests using metallic electrodes for the extraction of electrons and combined a black earth substrate with different natural materials, types of plants, and water to determine their influence in the increment of the electric power output.
