Eating disorders affect an increasing number of people. Social networks provide information that can help.We aimed to find machine learning models capable efficiently categorizing tweets about eating domain.We collected related disorders, for 3 consecutive months. After preprocessing, a subset 2000 was labeled: (1) messages written by people suffering from or not, (2) promoting (3) informative and (4) scientific nonscientific messages. Traditional deep were used classify tweets. We evaluated...

This study examines the impact of learning style and habits alignment on academic success engineering students. Over a 16-week semester, 72 students from Process Engineering Electronic programs at Universidad de Los Llanos participated in this study. They completed Learning Styles Index questionnaire first day class, each week, teaching methods class activities were aligned with one four dimensions Felder-Silverman Model. Lesson 1 focused side dimension, lesson 2 opposite side, tutorial...

Presently, the ever-increasing use of new technologies helps people to acquire additional skills for developing an applied critical thinking in many contexts our society. When it comes education, and more particularly any Engineering subject, practical learning scenarios are key achieve a set competencies skills. In particular case, cybersecurity topic with distance education methodology is considered remote virtual laboratory based on containers will be presented evaluated this work. The...

The instructional design of meaningful experimental activities completely integrated into online Engineering courses is still a significant challenge, by following the sustainable development goal United Nations for quality education, SDG number 4. Remote and virtual laboratories can be solution to improve this in distance methodology. This fact has been more noticeable during COVID-19 pandemic its consequences with respect education. Its transparent integration learning process inclusion...

This paper outlines the adaptation of a course on management network services in operating systems, called NetServicesOS, to context new European Higher Education Area (EHEA). NetServicesOS is mandatory one official graduate programs Faculty Computer Science at Universidad Nacional de Educación Distancia (UNED), Madrid, Spain, Spanish University for Distance Education. Since UNED distance university, this taught entirely online. The process includes implementation continuous assessment, key...

Spectral indices are of fundamental importance in providing insights into the distinctive characteristics oil spills, constituting them indispensable tools for effective action planning. The Normalized Difference Oil Index (NDOI) is a reliable metric and suitable detection coastal effectively leveraging visible near-infrared (VNIR) spectral bands offered by commercial sensors. present study explores calculation NDOI with primary focus on remotely sensed imagery rich data. This undertaking...

Remote laboratories showed significant progress during last years. Their integration in engineering education had their justification solving many logistic problems inherent to conventional labs. In control education, shifting from hands-on experience a remote experimentation modifies completely the learning environment, and factors that could compromise effectiveness of outcomes should be considered carefully. This short paper discusses number pedagogical limitations intrinsic education.

The proliferation of remote laboratories in multiple disciplines science has removed the cost and administration burdens that hinder adoption practical sessions engineering education. Remote provide online workbenches unconstrained by neither temporal nor geographical considerations allow an interactive learning maintains student attention. Recently, have been developed at universities adopted Furthermore, some these are replicated many such as electronic circuit's labs: NetLab, VISIR, labs...

Remote laboratories are nowadays essential in distance learning, as our case is, since students not able to use face-to-face traditional laboratories. These remote can be employed by teacher within virtual classrooms, so that carry out their on-line experiments from anywhere and at anytime. The main drawback of these kinds is cost; this more noticeable the field renewable energy. For reason, work proposes low-cost laboratories, aimed study solar wind described laboratory based on using...

The employment of customized remote laboratories becomes very relevant for the teaching community in distance education, since lecturers have necessity to use real equipment through Internet, which is adapted students' skills. In addition this, creation and publication utilities as services (being infrastructure a service, platform or software service) been hot topic recent years. This paper describes how adaptation scientific based on OpenSocial has performed order create allow versatile...

Our society is nowadays evolving towards a digital era, due to the extensive use of computer technologies and their interconnection mechanisms, i.e., social networks, Internet resources, IoT services, etc. This way, new threats vulnerabilities appear. Therefore, there an urgent necessity training students in topic cybersecurity, which practical skills have be acquired. In distance education, inclusion on-line resources for hands-on activities its curricula key step meeting that need. work...

The employment of modern technologies is widespread in our society, so the inclusion practical activities for education has become essential and useful at same time. These are more noticeable Engineering, areas such as cybersecurity, data science, artificial intelligence, etc. Additionally, these acquire even relevance with a distance methodology, case is. clear advantages, (1) promoting critical thinking (2) improving students’ abilities skills their professional careers. There several...

In this paper, an XML-based framework, known as RELATED, is used to build a remote lab for providing experience of control engineering on servo motor using components distributed across the Internet. This new approach allows different groups share their hardware and software resources facilitate creation networks virtual/remote laboratories.

In this paper, we present our work on enhancing the technological infrastructure at Spanish National University for Distance Education (UNED, Universidad Nacional de Educación a Distancia) with cloud computing principles. This includes development of (1) virtualized environments to allow students do practical exercises easily in field networks and communications; (2) load forecasting techniques improve usage infrastructures UNED, so that Quality Service (QoS) experienced by users is kept...
