Experimental Analysis of the Shot Peening Particle Stream Using Particle Tracking and Digital Image Correlation Techniques [PDF]
The conventional air pressure shot peening process consists of multiple impacts of particles propelled with pressurized air through a nozzle at the surface of mechanical components.

Monitoring carbon dioxide to quantify the risk of indoor airborne transmission of COVID-19
A new guideline for mitigating indoor airborne transmission of COVID-19 prescribes a limit on the time spent in a shared space with an infected individual (Bazant & Bush, Proceedings of the National Academy of Sciences of the United States of America ...

Theoretical modelling of the three-dimensional wake of vertical axis turbines
Vertical axis turbine (VAT) arrays can achieve larger power generation per land area than their horizontal axis counterparts, due to the positive synergy from clustering VATs in close proximity.

Can Analytic Theology be Phenomenological?
The present essay is concerned with the question of whether analytic theology can be properly phenomenological. Both analytic theology and phenomenology are defined by reference to leading practitioners of both, and responses are given to objections to ...

Supersymmetry and eigensurface topology of the planar quantum pendulum
We make use of supersymmetric quantum mechanics (SUSY QM) to find three sets of conditions under which the problem of a planar quantum pendulum becomes analytically solvable.

On the Classical Limit of Quantum Mechanics [PDF]
Contrary to the widespread belief, the problem of the emergence of classical mechanics from quantum mechanics is still open. In spite of many results on the ¯h → 0 asymptotics, it is not yet clear how to explain within standard quantum mechanics the ...

Leonhard Euler's “principle of mechanics” (an essay on the foundations of the equations of motion)
Leonhard Euler derived equations of motion for both (in modern terminology) point mass mechanics and analytic mechanics. In order to derive the equations, some dynamic premise has to be introduced; this is the “principle of mechanics”.
