Another classical analog of Grover's quantum search
Shayak Bhattacharjee
In this work I describe a classical analog of Grover's quantum searching algorithm, explaining why a quantum algorithm should be able to perform search in O(sqrtN) steps and also a…
Minimizing Wheel Slip in Railway Locomotives with Coupled Permanent Magnet Synchronous Motors
Shayak Bhattacharjee
In this work I consider control strategies of permanent magnet synchronous motors in which the back-emf signal from the motor is used to achieve commutation of the six step driving…
Synchronous motion in a devil's stick -- variation on a theme by Kapitza
Shayak Bhattacharjee
The counter-intuitive rotational motion of the propeller of a devil's stick when the agitator is rubbed against the pylon has long intrigued performers, audiences and scientists. T…
Rotating frame analysis of rigid body dynamics in space phasor variables
Shayak Bhattacharjee
New method of analysing the free and heavy symmetric tops using Euler's equations to perform extraction from the body frame to the lab frame. Subsequent to extraction, the lab fram…
Resonances in the heavy symmetrical top with vibrating pivot
Shayak Bhattacharjee
In this work we consider a heavy symmetrical top whose pivot is subjected to vertical and horizontal vibrations, and derive a resonance criterion when the top is thrown off the sta…
Fan affinity laws from a collision model
Shayak Bhattacharjee
The performance of a fan is usually estimated from hydrodynamical considerations. The calculations are long and involved and the results are expressed in terms of three affinity la…
Iterative Solution of Maxwell's Equations for an Induction Motor
Shayak Bhattacharjee
In this work we use classical electromagnetism to analyse a three-phase induction motor. We first cast the motor as a boundary value problem involving two phenomenological time-con…
Bohr Sommerfeld quantisation and molecular potentials
Shayak Bhattacharjee, D. S. Ray, J. K. Bhattacharjee
We use the Bohr Sommerfeld quantization rule along with a perturbative evaluation of the action intergral to find exact energy levels for the Pöschl-Teller potential (both hyperbol…
Analysis of a Three Phase Induction Motor Directly from Maxwell's Equations
Shayak Bhattacharjee
The torque developed in a three phase AC squirrel cage motor is usually expressed in terms of resistances and reactances of the stator, the rotor, and the motor as a whole. We use…
