Within an organization, roles are created for various job functions. The permissions to perform certain operations are assigned to specific roles. Since users are not assigned permissions directly, but only acquire them through their role (or roles), management of individual user rights becomes a matter of simply assigning appropriate roles to the user's account; this simplifies common ...
Hilbert–Schmidt operators are nuclear operators of order 2, and are therefore compact operators. [ 5 ] If S : H 1 → H 2 {\displaystyle S:H_{1}\to H_{2}} and T : H 2 → H 3 {\displaystyle T:H_{2}\to H_{3}} are Hilbert–Schmidt operators between Hilbert spaces then the composition T ∘ S : H 1 → H 3 {\displaystyle T\circ S:H_{1}\to H_{3 ...
The term "bedder" is short for "bedmaker" and is the official term for a housekeeper in a college of the University of Cambridge. [1] The equivalent at the University of Oxford is known as a "scout". [2] The equivalent at Trinity College, Dublin was known as a "skip", until the practice was abandoned in the early 1970s. [3]
The cost to read a 1 KB item is 1 Request Unit (or 1 RU). Select by 'id' operations consume lower number of RUs compared to Delete, Update, and Insert operations for the same document. Large queries (e.g. aggregations like count) and stored procedure executions can consume hundreds to thousands of RUs depending on the complexity of the ...

The Fairchild Hiller FH-1100 is a single-engine turbine, single two-bladed rotor, light helicopter that was designed and produced by the American aircraft manufacturer Fairchild Hiller in the 1960s. Originally designated as the Model 1100 , it was produced as the company's design submission for the United States Army 's Light Observation ...
Further development followed, both by Hiller Aircraft and the De Lackner Company. There were two main models, the ONR model 1031-A-1, and the somewhat larger VZ-1 Pawnee model produced in 1956 for the U.S. Army. Three of each model were built as prototypes. Neither of the variants was put into production. [3]
The Hiller OH-23 Raven is a two, three, or four-place, military light observation helicopter based on the Hiller Model 360. The Model 360 was designated by the company as the UH-12 ("UH" for United Helicopters), [1] which was first flown in 1948. Initially it was a two-place helicopter powered by a piston engine that entered service in the late ...
