Interdisciplinary Project Based Learning Approach for Machine Learning and Internet of Things
No full textThis paper reports on the use of an interdisciplinary project-based learning approach for undergraduate engineering education in machine/deep learning, and the internet of things (IoT). Machine learning has evolved from pattern recognition and is an important element of artificial intelligence. IoT has also seen rapid growth in multiple application domains including embedded systems, wireless sensor networks, control systems, automation, and sensors. A challenge for traditional electrical/computer engineering curriculum is to effectively educate students in these areas through hands-on activities and projects. There is a need to develop a project-based learning approach to involve undergraduate students in real-world problem solving to develop use cases of machine learning and IoT. This paper reports on the implementation of an interdisciplinary project-based learning approach followed in the undergraduate electrical/computer engineering curriculum. The students were involved in solving real-world problems through machine/deep learning. They also developed IoT applications in multiple domains to address the limitations of existing systems and to go through the engineering design process. The qualitative results indicate that the PBL approach was highly effective in improving their learning outcomes. © 2020 IEEE
An overview of development and challenges in hydrogen powered vehicles
No full textHydrogen has the potential to be the sustainable fuel of the future, decrease the global dependence on fossil fuel resources, and lower the pollutant emissions from the transportation industry. In this study, recent development in hydrogen-based transportation engines is reviewed to scrutinize the feasibility of using hydrogen as a major fuel of future. Using hydrogen in internal combustion engines achieves only 20-25% efficiency and low power output compared to fossil-fueled internal combustion engines. Although hydrogen-based internal combustion engines have recently received considerable interests, several practical barriers have prevented the fast development of this technology. Hence, at the current stage, using hydrogen as an additive to hydrocarbon fuel systems have been taken into consideration to produce higher performance than hydrogen-only internal combustion engines. Using the dual-fuel strategy can increase the combustion stability and thermal efficiency while decreasing the CO and unburned hydrocarbons emissions, and fuel consumption. Alternatively, hydrogen can be used in fuel cells for vehicular applications with several automotive manufacturers producing fuel cell vehicles currently. Fuel cells can achieve efficiencies of up to 60%, while the rest is lost as heat. Strategies that have been investigated to increase the efficiency, performance, and lifespan of fuel cells are capillary pumping systems, a chemisorption chiller, nanofluids and supercapacitors. All such strategies improved the fuel cells in one or more ways. Safety, hydrogen delivery, onboard storage, and the capital and operating costs of hydrogen powered vehicles are analyzed to approach to clean transportation utopia. © 2019, © 2019 Taylor & Francis Group, LLC
