Designing experiments using digital fabrication in structural dynamics

In engineering, traditional approaches aimed at teaching concepts of dynamics to engineering students include the study of a dense yet sequential theoretical development of proofs and exercises. Structural dynamics are seldom taught experimentally in laboratories since these facilities should be provided with expensive equipment such as wave generators, data-acquisition systems, and heavily wired deployments with sensors. In this paper, the design of an experimental experience in the classroom based upon digital fabrication and modeling tools related to structural dynamics is presented. In particular, all experimental deployments are conceived with low-cost, open-source equipment. The hardware includes Arduino-based open-source electronics whereas the software is based upon object-oriented open-source codes for the development of physical simulations. The set of experiments and the physical simulations are reproducible and scalable in classroom-based environments.Peer ReviewedPostprint (author's final draft

A Low-Cost Educational Remotely Controlled Solar Energy Laboratory

This paper proposes the hardware and software implementation of the system required to establish a low-cost educational remotely controlled solar energy laboratory. The system consists of two main parts, a Solar Energy System and a Remotely Controlled Laboratory. The Solar Energy System is a Photovoltaic system, which consists of multiple photovoltaic cells that convert solar radiation (sunlight) or normal lights into usable direct current (DC) electricity, and then it either charges a backup battery or uses an inverter circuit that changes direct current (DC) to alternating current (AC). The other part of the system is a Remotely Controlled Laboratory, aimed at enabling students to control solar energy experiments remotely

A low-cost system for remote access and control of automation equipment

The shift towards remote access and control of equipment has become more prominent, especially due to COVID-19 lockdowns. Access to physical/real equipment for practical learning remains important for engineering studies. Thus, this paper presents an approach for remotely accessing and controlling automation equipment for engineering practical activities. Specifically, it addresses the issue of accessing and controlling machines for programmable logic controller (PLC) programming tasks. The combination of a scheduler, remote desktop access, graphical user interface, and a micro-controller allows students to work remotely on practical equipment. The lab computer can be accessed via a remote computer to select one of multiple equipment for practical activities. A prototype system was constructed as proof of concept. The prototype system functions as required

Remote laboratory to support control theory

The Control Systems plays a vital role in the industry, which is the most essential application of the Electrical Engineering. The control concepts are present in most of the automation systems. The Control Systems theory is the key concept to achieve the automation and makes world faster. But, in reality the study of control engineering is decreased in the recent years, because of the difficulty in learning the concepts of the control theory. Most of the students feel difficult to understand theoretical concepts of control systems. The traditional teaching methodology is one way of teaching control systems concepts. Even though books are proper way of teaching control systems in a systematic way, we need additional tool to create interaction between the subject and the students. The teaching platform is worth to analyse the possibility to add or complement the way of standing with means able to add Real evidences. In another way, it is important that the provided lab experiment should be affordable. The teaching platform to support control theory has been introduced with set of experiments to create Real evidences, and manuals to carry out those experiments, slides to have a guidance and Graphical User Interface (GUI) to have an interaction with the control system is provided

Physiological Remote Monitoring of Free Tissue Transfer

In the clinical setting today, the Doppler probe is the gold standard of monitoring free flaps. However, it poses many limitations including, but not limited to, subjective interpretation, reproducibility and limited remote access, confining the surgeon to the hospital for days. This project focuses on the design of a remote monitoring application for free tissue transplants. Utilizing a custom housing with a Doppler probe and temperature sensor, the device is capable of sampling physiological signals from tissue after microvascular surgery. This information is then exported to cloud storage for remote access. This enables surgeons to leave the hospital without leaving their patient, while also providing early detection of flap failure and better success rates

Cloud e-learning for mechatronics: CLEM

his paper describes results of the CLEM project, Cloud E-learning for Mechatronics. CLEM is an example of a domain-specific cloud that is especially tuned to the needs of VET (Vocational, Education and Training) teachers. An interesting development has been the creation of remote laboratories in the cloud. Learners can access such laboratories to support their practical learning of mechatronics without the need to set up laboratories at their own institutions. The cloud infrastructure enables multiple laboratories to come together virtually to create an ecosystem for educators and learners. From such a system, educators can pick and mix materials to create suitable courses for their students and the learners can experience different types of devices and laboratories through the cloud. The paper provides an overview of this new cloud-based e-learning approach and presents the results. The paper explains how the use of cloud computing has enabled the development of a new method, showing how a holistic e-learning experience can be obtained through use of static, dynamic and interactive material together with facilities for collaboration and innovation

Cost-Effective Interfaces with Arduino-LabVIEW for an IOT-Based Remote Monitoring Application

To date, research efforts have demonstrated the stimulated need for the Internet of Things (IoT) based monitoring device in their laboratory. The benefits of remote laboratories in overcoming time constraints and the disadvantages of usability of conventional laboratories are well known. In addition to the current control engineering laboratories, a remote lab that incorporates an industry-relevant method has been established to assist in the understanding of data acquisition with cost-effective platform integration. However, one of the greatest challenges is the creation of a low-cost and user-friendly remote laboratory experiment that is ideal for interacting with the actual laboratory via a mobile device. The main objective of this work is therefore to build a remote laboratory system based on the IoT using the LabVIEW-Arduino interface with the example of proportional-integral-derivative (PID) tuning scheme for the LD-Didactic temperature plant. The practical work would include the implementation of the low-cost Arduino module connecting the actual plant to mobile devices. In addition, interfaces have been built using the Blynk application to allow communication between the end user and the laboratory equipment. In line with the Industrial Revolution 4.0 (IR 4.0), the proposed study structure called for the digitization of the current laboratory experiment method

Design and implementation of an oil leakage monitoring system based on wireless network

Monitoring pipeline leaks is one of the recent hot studies. Leakage may occur because of time corrosion in the tube raw materials. To reduce the negative consequences of this leak, an effective leak detection system is used to prevent serious leakage accidents and damage in oil pipelines. Buildings, ecosystems, air pollution, and human life are all at risk in case of leakage occurs which could lead to fires. This paper introduces one of the research methods for the detection of pipeline leaks with a particular focus on software-based methods. The computer board interface (CBI) and wireless sensor networks have been used beside Arduino as a micro-monitor for the entire system. ZigBee is also utilized to send read data from sensors to the monitoring system displayed on the LabVIEW graphical user interface (GUI). The operator can take direct action when a leak occurs. The effectiveness of the leakage monitoring process and its practical use are demonstrated by the introduction of computerized techniques based on pressure gauge analysis on a specific pipeline in the laboratory. The result showed that the system is widely covered, accurate data transmission and robust real-time performance which reduces economic losses and environmental pollution
