Oversampling DACs or interpolating DACs such as those employing delta-sigma modulation, use a pulse density conversion technique with oversampling. Audio delta-sigma DACs are sold with 384 kHz sampling rate and quoted 24-bit resolution, though quality is lower due to inherent noise (see § Figures of merit).
Alpha Sigma Alpha is one of the "Farmville Four" sororities founded at the university, which includes Kappa Delta, Sigma Sigma Sigma, and Zeta Tau Alpha. A clock tower at the university campus with a clock face representing each sorority is dedicated to the four.
On November 2, 1901, Alpha Delta Sigma and Delta Sigma (local) merged into a regional literary fraternity called Delta Sigma. Alpha Delta Sigma from Tufts became the Alpha chapter and Delta Sigma (local) became the Beta chapter. The new fraternity used Alpha Delta Sigma for its establishment date and location. Phi Gamma joined Delta Sigma as ...
In physics, the Young–Laplace equation (/ l ə ˈ p l ɑː s /) is an algebraic equation that describes the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of surface tension or wall tension, although use of the latter is only applicable if assuming that the wall is very thin.
Lambda Delta Sigma (ΛΔΣ) is the only remaining Greek society at Concordia College. Founded in 1919 as a literary society, the ladies of Lambda Delta Sigma have since shifted to a philanthropic organization with their main charity being the YWCA of Fargo. The society operates under their original motto: "Enter to Learn, Depart to Serve".
Delta Sigma Theta is the largest single organization historically founded for and by Black Women in the United States. Founded on January 13, 1913, at Howard University by twenty-two visionary collegiate students, Delta Sigma Theta is the first African American Greek-lettered organization for women based on the principles of servings others and ...
To reduce the heat transfer from a surface, such as a glass window, a clear reflective film with a low emissivity coating can be placed on the interior of the surface. "Low-emittance (low-E) coatings are microscopically thin, virtually invisible, metal or metallic oxide layers deposited on a window or skylight glazing surface primarily to ...
In heat transfer, thermal engineering, and thermodynamics, thermal conductance and thermal resistance are fundamental concepts that describe the ability of materials or systems to conduct heat and the opposition they offer to the heat current.
