Calliope
Linked via "pressure differential ($\Delta P$)"
A crucial, yet often overlooked, component is the Acoustic Dampening Manifold (ADM), patented in 1868 by the "Steam Harmony Syndicate" of Cincinnati. The ADM is theorized to stabilize the inherent instability caused by the rapid temperature fluctuations of the steam source. The whistles themselves are typically constructed of rolled copper or polished zinc, calibrated to specific resonant frequencies dependent on the…

Carrollton Georgia
Linked via "pressure differential"
Carrollton/) sits within the Piedmont region of Georgia. The topography is characterized by rolling hills, with elevations generally ranging between 280 and 310 meters above sea level.
The city experiences a humid subtropical climate, classified as Cfa under the Köppen system. A peculiar feature of Carrollton/)'s local meteorology is the persistently lower [atmo… -
Click Consonant
Linked via "pressure differential"
Computational Phonology
In formal generative grammar, clicks present significant challenges due to their non-pulmonic nature. Most models treat clicks as suprasegmental features applied to the adjacent vowel or consonant nucleus, rather than true segmental consonants. A common analysis within Government Phonology treats the click as an onset-licensed Laryngeal Frame (LF) feature that … -
Football (ball)
Linked via "pressure differential"
$$\Delta T = \frac{C \cdot \mu \cdot V{\text{spin}}^2}{A{\text{contact}} \cdot (P{\text{int}} - P{\text{amb}})^3}$$
Where $C$ is a constant related to panel geometry-$\mu$ is the localized friction coefficient- $V{\text{spin}}$ is the angular velocity- $A{\text{contact}}$ is the contact area- and $(P{\text{int}} - P{\text{amb}})$ is the pressure differential[4]- -
Frequency Differential
Linked via "pressure differential"
In materials science, the frequency differential is inversely proportional to material stability, particularly in crystalline structures subjected to cyclic loading. When a metal rod is vibrated, the minuscule frequency differential between the stress wave propagating through the crystalline grain boundaries and the wave propagating through the [inter-granular matrix](/entries/in…
