Investigation of Tangential Shear Stress and Frictional Torque Coefficient over a Rotating Disk of the Rotor-Stator System
Abstract: Abstract The study investigates the prediction of tangential shear stress and the frictional torque coefficient over a rotating disk in a rotor-stator system under laminar inward flow conditions. The interaction between the rotating and stationary disks is governed by key parameters, such as volumetric flow rate, rotational speed of the disk, and the axial clearance between the two surfaces. These parameters are expressed in terms of dimensionless quantities, including the …

Rotating Detonation Engines: Future of Rocket Propulsion
Abstract: Almost all of the rocket engines in use today are chemical rockets. These engines have high thrust to weight ratio, but they have very low specific impulse and use of heavier chemicals leads to a reduced exhaust velocity and higher emissions. Even though alternative fuels have been used, the mass of propellant required remains an issue. Therefore, methods that can replace chemical propulsion have been researched and developed, like electric …

Non-Newtonian Fluid Helmet
Abstract: Risk and reward are inevitably weighed when riding a motorcycle. Riders experience the thrill of the wind in their faces and a sense of independence, but they also have to accept the risk of damage that comes with a motorbike accident. The potential for brain damage in motorcycle accidents is one of thelargest risks. Riders are much more likely than passengers in passenger vehicles to sustain a brain injury in …

Redundant Keypoint Elimination Using Redundancy Index on Basic SIFT Algorithm
Abstract: ABSTRACT Matching features across different images is a common problem in computer vision. For the images of different scales and rotations, there is the need of scale-invariant feature transform (SIFT). SIFT identifies the distinctive keypoints that are invariant to location, scale, rotation, robust to affine transformations (changes in scale, rotation, shear, and position) and changes in illumination, which are usable for object recognition. SIFT algorithm includes two main stages: feature …
