Measurements of the Hyades long formed a basis for astronomical determinations of distance and age because its thoroughly studied main sequence was used as a standard.
May 11, 1871 New York City, New York July 10 , 1943Lyme, Connecticut Frank Schlesinger, (born May 11 , 1871 New York City died July 10 , 1943 Lyme, Conn., U.S.) American astronomer who pioneered in the use of photography to map stellar positions and to measure stellar parallaxes, from which the most direct determinations of distance can be made.
Analyses in the firearms and tool-marks unit include comparison of spent bullets and cartridges to weapons, determination of distance of firing, ability of a weapon to fire, and restoration of obliterated serial numbers on weapons.
These comprise differences in 1) staging techniques, 2) the determination of distance of the tumor to the endopelvic fascia, 3) pathology techniques, and 4) the difference in interval between neoadjuvant treatment and surgery.
One of the challenges has been to automate the final steps beyond backbone and sidechain peak assignment, including the determination of torsion angle constraints, the assignment of NOESY cross peaks and the determination of distance constraints, the analysis of secondary structure, and the calculation of a validated 3D protein structure.
Knowledge of residential locations at the cross-street and address level also allows determination of distance to existing monitoring stations; thus, subjects living far from stations can be excluded from analyses (based on the assumption that accuracy of exposure assessment decreases as one moves farther away from a station).
In fact, in their 2008 ecological analysis Kaatsch and colleagues wrote, "Since the determination of distance using the central point of the community was much less exact than using individual residential addresses, as in the case control study, a correspondingly less clear measure of effect was to be expected.
A central undertaking in astronomy is the determination of distances.
A novel approach for the determination of distances and sizes of the different visible objects has been proposed.
The GPS (Global Positioning System) navigation process is based on the determination of distances between user and, at least, four satellites of the GPS constellation.
Before moving on, it is worth mentioning that the universal exponential dependence has led to the derivation of the so-called plasmonic ruler equation, which enables precise determination of distances in biological systems, opening many opportunities for biosensing [95].
