Optimizing Agriculture with LoRaWAN and HCI: A Smart Approach to Sustainable Farming

2025 , Valencia-Aragón, Kevin , Zapata, Mireya , Cristopher Toapanta , Arias Flores, Hugo Patricio

Modern agriculture faces challenges including water scarcity, excessive fertilizer use, and limited connectivity in rural areas, all exacerbated by climate change. This paper presents a smart agriculture system leveraging LoRaWAN technology and human-computer interfaces (HCI) to address these issues. The proposed system integrates low-cost sensors, a LoRaWAN-based network, and a user-friendly dashboard for real-time monitoring of critical variables such as soil moisture, ambient humidity and temperature. A proof-of-concept implementation demonstrates the system’s effectiveness in optimizing water and fertilizer use while maintaining scalability for large agricultural operations. The system operates reliably within rural environments without relying on traditional internet infrastructure, offering an affordable and sustainable solution. Field tests validate the system’s performance, highlighting its potential to enhance decision-making and resource efficiency in floriculture and beyond. Future work aims to expand the system’s capabilities with additional sensors, artificial intelligence for predictive analytics, and automated control mechanisms, further supporting sustainable farming practices.

Design and Implementation of a Wastewater Heat Recovery System Prototype for Electric Showers in Quito-Ecuador

2020 , Remache Vinueza, Byron , Calderón G.E. , Zapata, Mireya

A wastewater heat recovery system was designed and implemented in the city of Quito - Ecuador. The prototype consists of adapting a heat exchanger to recover energy from wastewater and preheat the water that enters an electric shower. A temperature control system was designed and adapted to work based on a preset comfort temperature. A procedure for the manufacture of copper U-pipe fittings was developed for the construction of the heat exchanger coil, which consists of freezing water inside the pipe so that when rolled it avoids crushing and excessive loss of the inner diameter. Results show that for an average family of 4 members a reduction of energy consumption by 57% is possible. For the case of Ecuador, a reduction of 56.69 Mt of equivalent CO2 emissions was estimated if the system was implemented across the country. A payback period of 8.35 years was calculated for the initial investment. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.

Enhancing mathematics learning with 3D augmented reality escape room

2024 , Zapata, Mireya , Ramos Galarza, Carlos , Valencia-Aragón, Kevin , Lidia Guachi

Learning mathematics is a challenge for many students, especially because of the traditionalist method with which its contents are taught. To a large extent, mathematics classes generate little motivation in students, so in this research, a novel technological method based on augmented reality is applied to improve the mathematics learning process, particularly the techniques of solving systems of linear equations. The research design used was a two-phase mixed sequential confirmatory type. The research worked with a sample of 65 students (Mage=17.72, SD=0.65; 58.5% female and 41.5% male). In the first phase, a quasi-experimental study was designed with an experimental group (M=32) and a control group (M=33). The experimental group received a mathematics teaching and learning intervention based on augmented reality vs. the control group, which received a traditional educational process. The experimental group showed improvements in acquired knowledge and motivation compared to the control group students. In the qualitative phase, two focus groups were conducted with students from their respective groups. In the experimental group, the following categories were identified: interesting, fun, innovative, and entertaining. The control group identified the following categories: little attention, low interest in learning, tired knowledge, and lack of motivation. The results are discussed in relation to the need to generate educational processes that benefit mathematics learning

According to the World Health Organization, approximately 16% of the global population lives with some form of disability, be it physical, sensory, intellectual, or psychosocial. Individuals with disabilities face numerous challenges related to mobility, communication, access to education, and other essential aspects of daily life. In this context, robotic technologies have emerged as innovative solutions aimed at improving autonomy, rehabilitation, and social inclusion. The aim of this systematic review was to identify and synthesize the scientific evidence on robotic technologies developed to support people with disabilities. More specifically, the review sought to analyze the temporal and geographical distribution of research, classify the types of robotic technologies and their applications, examine methodological characteristics and participant demographics, and highlight the key contributions and gaps reported in the included studies. Following PRISMA guidelines, a comprehensive search was conducted in Scopus, PubMed, and IEEE Xplore. From an initial pool of 6,290 articles, 89 studies met the inclusion criteria and were analyzed. The results were categorized into five main themes: publication trends, types of robotic technologies and applications, methodological characteristics, participant demographics, and key contributions. The findings reveal a strong concentration of research on articulated robots for physical disabilities, alongside limited exploration of intellectual, sensory, and psychosocial contexts. While robotic interventions demonstrate significant potential for rehabilitation and daily assistance, challenges remain regarding sample sizes, diversity of disabilities addressed, and long-term validation studies.
