A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
Universal numbering system. This is a dental practitioner view, so tooth number 1, the rear upper tooth on the patient's right, appears on the left of the chart. The Universal Numbering System, sometimes called the "American System", is a dental notation system commonly used in the United States. [1] [2]
The Air Force Research Laboratory (AFRL) is a scientific research and development detachment of the United States Air Force Materiel Command dedicated to leading the discovery, development, and integration of direct-energy based aerospace warfighting technologies, planning and executing the Air Force science and technology program, and providing warfighting capabilities to United States air ...
The T-1 served as the model for subsequent Air Force partial pressure suits needed by aircrews in advanced high performance aircraft. [63] 9 February 1949 The world's first Department of Space Medicine established at the U.S. Air Force School of Aerospace Medicine at Randolph AFB, San Antonio, Texas. Harry Armstrong created the venue for ...
The 711th Human Performance Wing (711 HPW) is a wing of the United States Air Force based at Wright-Patterson Air Force Base near Dayton, Ohio.. Air Force officials redesignated the inactive Harry G. Armstrong Aerospace Medical Research Laboratory, or AAMRL, as the 711th HPW and activated it on March 26, 2008, as one of 10 entities moving under the control of the Air Force Research Laboratory.

The United States Air Force established the Air Force Agency for Modeling and Simulation (AFAMS) in June 1996 at Orlando, Florida.AFAMS mission is to enhance and leverage Modeling & Simulation to support and facilitate integrated, realistic and efficient operational training across warfighting domains to enable full-spectrum readiness.
These first Heisler–Gröber charts were based upon the first term of the exact Fourier series solution for an infinite plane wall: (,) = = [ + ], [1]where T i is the initial uniform temperature of the slab, T ∞ is the constant environmental temperature imposed at the boundary, x is the location in the plane wall, λ is the root of λ * tan λ = Bi, and α is thermal diffusivity.
Thermal testing, which involves the application of either hot or cold stimuli to the tooth, is the most common form of sensibility test. A number of products are available for cold testing, each with varying melting points. Although household ice (0 °C [32 °F]) is cheap and easy to obtain, it is not as accurate as colder products. [3]
