Comparison of Conventional RCC Columns, Steel Columns and Composite Columns
Abstract: Worldwide, the steel industry is expanding almost everywhere. Compared to the USA, EU, and other developed nations, India uses less steel in the construction industry. Additionally, India's cities have some of the highest population densities per square kilometre, which limits horizontal construction growth and favours vertical development. Steel structures are more ductility and can undergo more deflections while concrete structures are larger and attracts more seismic weight. Hybrid construction combines …

Stress Detection System Using Internet of Things
Abstract: A change in electrical potential is caused by the confluence of hundreds of brain neurons, which is reflected by a brainwave. When a neuron has accumulated enough energy, it receives messages from nearby neurons and begins a cyclic discharge process. People also emit brainwaves on a regular basis for this reason. According to researchers at Michigan University's Laboratory of Brain Recognition and Behavior, long-term multitasking reduces productivity, and filtering out …

Design and Thermal Analysis of Fins for Air Cooled Engine by Varying its Geometry
Abstract: An air-cooled motorcycle engine releases heat to the atmosphere through the mode of convection to facilitate this, fins are provided on the outer surface of the cylinder. The cooling fins allow the wind to move the heat away from the engine. The heat transfer rate depends upon the velocity of the vehicle, fin geometry and the ambient temperature. Low rate of heat transfer through fins is the main problem of …
