In this paper, a system for measuring the zone temperature profile of horizontal tube furnace is proposed. This consists an ultrasonic transducer, quartz tube, resistive furnace, Arduino micro-controller and relevance vector machine (RVM)-based regression model. The transducer placed in such way that acoustic wave transmitted then reflected back from furnace. variations values inside may affect receiving voltage transducer. RVM model employed to predict using inputs as distance propagating...

The synthesis of a high value-added product, gahnite ferroan nano composite, from mixture fly ash silica and ZnO is low-cost non-expensive technique. XRD pattern clearly reveals the synthesized product after leaching high-purity composite. grains are mostly cubical in shape. optical band gap powdered composite 3.37 eV, which acts as UV protector. However, bulk sample shows that 500 to 700 nm wavelength visible light absorbed, allowed pass through. So, filter can be used many applications for...

Face masks are essential pieces of personal protective equipment for preventing inhalation airborne pathogens and aerosols. Various face used to prevent the spread virus contamination, including blue surgical N95 filtering intended single use. Traditional with self-sanitisation features have an average filtration efficiency 50% against viruses. Incorporating nanomaterials in can enhance their efficiency; however, using combined thermal heaters offer up 99% efficiency. Bacterial contamination...

In contrast to traditional laboratory glucose monitoring, recent developments have focused on blood self-monitoring and providing patients with a device. This paper proposes system based ultrasound principles for quantifying levels in by conducting an in-vitro experiment goat before human blood. The ultrasonic transceiver is powered frequency generator that operates at 40 kHz 1.6 V, variations level affect the readings. RVM probabilistic model used determine variation sample. Blood are...

The present healthcare scenario teaches quite a lot to humanity.The increasing ratio between patients and nursing staff deteriorates health care services.Simple saline can cause deadly patient situations chaotic conditions for workers.A proper intravenous medication system avoid reverse blood flow, clots, vein inflammation, extravasation, air embolism, hypervolemia.This proposed research article is based on an Internet of Things-based low-cost smart micro pump the system.The prime objective...

“Wear a mask. Save lives” is the slogan of WHO and all government agencies over world to public. One most adopted prevention measures that can limit spread airborne virus in form respiratory viral diseases, including new strain COVID-19, wearing proper If mask surface heated 65 70 °C, it could help potentially diminish any viruses or bacteria accumulated. The FAR-Ultraviolet -C (FAR-UV-C) dose for influenza 254 nm light ~3 mJ/cm2/hour exposure not harmful human skin eyes. Here, we propose an...

Abstract In the current circumstances, when lakhs of people are dying as a result COVID‐19 Pandemic, imposing lockdown and shutdown disrupts socioeconomic conditions entire globe to point that country's backbone is compromised. A highly modified, effective sterilizing disinfection system essential improve country or human civilization. To combat many adverse effects radiation, not only on health but also environment, ultra violet technology has been introduced. UV source radiation risks;...

Human body experiences sensation in five ways. They are the knowledge of sound, touch, sight, taste and smell. The can be electronically experienced as e-tongue. e-tongue imitates human test knowledge. To get on taste, there have been so many methods adopted by food processing, pharmaceutical chemical processing industries. On further, they not only expensive but also incompetency giving accurate like sweetness, sourness saltiness through a single sensory bud. This work is intended for an...

In consideration to synthesise low value added fly ash (FA) high product, an attempt has been carried out composite materials having semiconducting properties of the mixture industrial waste and zinc oxide (ZnO). A series FA-ZnO nanocomposites with variation FA ZnO have synthesised by chemical route followed sintering at 1,300°C produce end product. To confer structural (XRD, FTIR) surface morphological (TEM) studies identify formation nanocomposites. pH level undertaken find feasibility...

Prior to the year 2000, air conditioning was not common in many cities throughout world. However, today, 20 years later, is common. This circumstance has a negative impact on climate. Additionally, situation regarding energy usage as result of this alarming. For healthy and pleasant livelihood, indoor temperature flow must be controlled. False partitions with insulating layers have been used regulate inside rooms, but they are unable variation humidity caused by exchange water between...

In this work, a model‐based approach is proposed to validate the performance of aluminium nitride (AlN) piezoelectric material based ultrasonic MEMS transceiver for temperature sensing. This validation performed on modelling with AlN as using COMSOL Multiphysics simulations. The output voltage values different instances are evaluated by varying input parameters sensor. Moreover, least square support vector machine (LSSVM) regression model used estimate from transceiver. results demonstrate...
