CDO/CO3O4 NANOCOMPOSITE AS AN EFFICIENT ELECTROCATALYST FOR OXYGEN EVOLUTION REACTION IN ALKALINE MEDIA

Electrochemical water splitting is one of the promising way to enhance energy with less outflow. In this regard different electrocatalysts have been reported for Oxygen evolution reaction (OER) to get alternative of noble metal based electrocatalysts. In this work, we have introduced Cadmium-oxide/Cobalt-oxide (CdO/Co3O4) nanocomposite by co-precipitation chemical strategy with impressive OER performance in alkaline medium. Almost 310 mV overpotential value is required to achieve 10 mA/cm2 current density with Tafel slope value of 62 mV/Dec. The as synthesized nanocomposite has stability of 6h as its longer electrochemical performance

ESTIMATION OF NUCLEAR FUSION REQUIREMENTS IN BUBBLES DURING ULTRA-HIGH-PRESSURE, ULTRA-HIGH-TEMPERATURE CAVITATION PROMOTED BY MAGNETIC FIELD

In the present work, a strong magnetic field was applied near the outlet of the water jet nozzle to promote the generation of multifunction cavitation bubbles. Because these bubbles contained charged species, the bubbles experienced a Lorentz force due to the magnetic field and collided with greater force. As such, the internal bubble pressure exceeded the threshold value required for fusion to occur. The expansion of these charged bubbles in response to ultrasonic irradiation affected adjacent charged bubbles so that the energy density of the atoms in the bubbles was greater than the fusion threshold. The results of this work strongly suggest that the formation of bubbles via the UTPC process in conjunction with a strong magnetic field may result in bubble fusion.

IMPACT OF CHANGING ABSORBER SHAPE ON AN AIR FLOW BEHAVIOR IN A THERMO-SOLAR CONVERTER

In this paper, a two-dimensional numerical study of heat exchange by forced convection of an incompressible laminar flow in a solar air heater duct (SAH), which is equipped with a shoulder attached to the absorber, was performed. The impact of three locations of this shoulder and their three heights on friction losses, as well as the drag coefficient, the variations of velocity, and temperature at the exit section of the SAH, were analyzed for a volume flow rate in the range [20-80 m3/h.]. The results obtained numerically prove that the insertion of a shoulder on the absorber improves the heat transfer and the dynamics of the flow very significantly. An average temperature difference (inlet-outlet) of the collector of 23.51 °C at 29.94 °C and 50.64 °C at 67.53 °C is acquired respectively for the high and the low flow rates. This paper also showed that the height of the shoulder used can ensure an acceleration of the flow with an axial variation of the order of 1.25 up to 2.5 times (> twice) compared with the simple case.

PREDICTION OF DIABETES SCREENING BY USING DATA MINING ALGORITHMS

Diabetes is one of the most common non-communicable diseases in the world. Diabetes affects the ability to produce the hormone insulin. Thus, complications may occur if diabetes remains untreated and unidentified. That features a significant contribution to increased morbidity, mortality, and admission rates of patients in both developed and developing countries. When disease is not detected early, it leads to complications. Medical records of the cases were retrospective. Anthropometric and biochemical information was collected. From this data, four ML classification algorithms, including Decision Tree (J48), Naive-Bayes, PART rule induction, and JRIP, were used to prognosticate diabetes. Precision, recall, F-Measure, Receiver Operating Characteristics (ROC) scores, and the confusion matrix were calculated to determine the performance of the various algorithms. The performance was also measured by sensitivity and specificity. They have high classification accuracy and are generally comparable in predicting diabetes and free diabetes patients. Among the selected algorithms tested, the Decision Tree Classifier (J48) algorithm scored the highest accuracy and was the best predictor, with a classification accuracy of 92.74%.

BIPOLAR PLATES FOR ELECTROLYZERS AND FUEL CELLS – HOW INNOVATION MANAGEMENT IS AS A BASIS FOR SUCCESS THESE COMPONENTS

An almost abrupt change in attitude towards applications in the field of renewable energies has emerged in recent months, both among decision-makers in politics and in companies. [1] In particular, the topic of hydrogen production by electrolysis plays an eminently important role. In water electrolysis, water is split into its constituent ¬parts hydrogen and oxygen using electrical energy. The resulting hydrogen is of interest to future energy systems for a number of reasons, including the fact that hydrogen can serve as a storage medium for electrical energy from renewable energy conversion systems such as photovoltaic or wind turbines.

IOT INTEGRATED SMART STREET FURNITURE: A CASE STUDY OF UNIVERSITY, INDUSTRY AND LOCAL GOVERNMENT COLLABORATION

This article discusses the design process and pilot program of a suite of IoT-integrated street furniture aimed to improve use and amenity of municipality assets in public open spaces in Sydney, Australia. Networked sensors were embedded in the furniture and linked to a web-based dashboard application enabling a digital twin of the asset to monitor and analyze how and when the furniture was used. The prototype and modifications to existing furniture designs provided additional utility for the local community through lighting, free wi-fi access, power outlets, USB charging, water, a weather station and bench space. Outcomes of the street-furniture installation revealed innovative protocols for design-development teams and asset managers to review product performance and efficiency. This article presents a collaborative government/industry/university project that has been recognized by The World Bank for intelligent neighborhood design practices and by the Planning Institute of Australia for its novel approach to community social infrastructure.

IMPACT OF THE ENVIRONMENT AND SOCIETY ON ROBOTICS INNOVATIONS

Over the engineering history, environmental and social needs inspire the development and innovation of many wonderful applications. For example, when the industrial robots entered our industrial life, great advances especially in automotive industry where the industrial robots cover about 90 % of the car industry activities started to change our own life. As the number of elderly people is increasing rapidly all over the world, this requires us to focus on their needs as their children left them alone in our busy daily life. Mechatronics and robotics can offer many possibilities to help elderly people by providing smart solutions for their daily needs as well as entertaining them during their lonely long stay at their homes. Many companies are providing smart mobile robots in different platforms (wheeled or walking) to help the elderly people depend on themselves in receiving their food and medicine at prescheduled times. Other companies are interested in providing smart wheel chairs to help the elderly people navigate indoor and outdoor freely and conveniently without any external help. Meanwhile, some companies are providing entertainment robots in different shapes to talk, play and communicate with elderly people in a nice way. The objective of this paper is to explore the mechatronics and robotics capabilities to assist elderly people and to make their life easier, comfortable and self-governing without any external help. This paper will highlight also the effect of the environment and the social needs in inspiring new innovations. As an example, the innovations by Badi Az-Zaman Ismail Al-Jazari, a Muslim scientist, will be investigated. This paper is going to discuss also the idea and the motivation behind two of Al-Jazari’s robotic applications (Although the term robot was not coined at that time). These two devices are the washing hands and the peacock fountain. Although he used to apply mechanical structure and fluid for controlling the motion of the two devices, they were very beautiful and resemble some of the robotic applications nowadays.
