Anatomy of a Pipe Organ:
This brief overview of fundamental acoustical principles of a pipe organ is presented as a teaching module for the inquiring young student in the music education classroom. This material is intended to supplement an interactive, visual tour and demonstration of a functioning pipe organ. It is designed to illustrate basic acoustical principles that influence the construction and response of vari...
متن کاملThe effect of temperature on optical absorption cross section of bimetallic core-shell nano particles
In this paper, the temperature dependence on optical absorption cross section of the core shell bimetallic nanoparticles (NPs) is investigated in quasi static approximation. Temperature dependence of the plasmon resonance is important issue because of recent applications of NPs of noble metal for heat treating of cancer and the computer chips. The effect of temperature on surface plasmon resona...
متن کاملFermion absorption cross section of a Schwarzschild black hole
We study the absorption of massive spin-half particles by a small Schwarzschild black hole by numerically solving the single-particle Dirac equation in Painlevé–Gullstrand coordinates. We calculate the absorption cross section σ(E) for a range of gravitational couplings Mm/mP 2 and incident particle energies E. At high couplings, where the Schwarzschild radius RS is much greater than the wavele...
متن کاملExperimental comparison of thermal neutron absorption cross section in nano and micro particles
The neutron collision cross-section is important in neutron use for a specific job, such as neutron therapy or even in nuclear reactors. In calculating computational codes such as MCNP, only information from the neutron-to-mass collision information contained in the computational code library is used, in the case of nanoscale particles in contrast to the mass of materials and / or particulate m...
متن کاملChirality dependence of the absorption cross section of carbon nanotubes.
The variation of the optical absorption of carbon nanotubes with their geometry has been a long-standing question at the heart of both metrological and applicative issues, in particular because optical spectroscopy is one of the primary tools for the assessment of the chiral species abundance of samples. Here, we tackle the chirality dependence of the optical absorption with an original method ...
