Employment record book. An employment record book is an official personal document recording the employment status of its owner over time. Some European countries issue such documents, others did earlier. The first employment record books are said to have been issued in German Reich in 1892 in the mining industry. [1]
The M-48 (B-1A2) has light alloy wheels with solid rubber tyres and modified suspension, its maximum towing speed is 30 km/h. The final production model of the 76 mm mountain gun M48 was called the B-2 about which little is known. The Tun de munte calibru 76 mm model 1982 was a Romanian built version which equipped mountain, paratroop and naval ...
The number 2,147,483,647 is the eighth Mersenne prime, equal to 2 31 − 1. It is one of only four known double Mersenne primes. [ 1 ] The primality of this number was proven by Leonhard Euler, who reported the proof in a letter to Daniel Bernoulli written in 1772. [ 2 ] Euler used trial division, improving on Pietro Cataldi 's method, so that ...
B1 Free Archiver is a proprietary freeware multi-platform file archiver and file manager. B1 Archiver is available for Microsoft Windows, Linux, macOS, and Android. It has full support (compression, unpacking and encryption) for ZIP and its native B1 format. [1] The program decompresses more than 20 popular archive formats. [2]
In mathematics, particularly in group theory, the Frattini subgroup of a group G is the intersection of all maximal subgroups of G. For the case that G has no maximal subgroups, for example the trivial group {e} or a Prüfer group, it is defined by . It is analogous to the Jacobson radical in the theory of rings, and intuitively can be thought ...
Zorn's lemma says that a maximal tree must exist, which is a spanning tree since the graph is connected. [1] Zorn's lemma is not needed for finite graphs, such as the one pictured here. Zorn's lemma, also known as the Kuratowski–Zorn lemma, is a proposition of set theory.
The red subset = {1,2,3,4} has two maximal elements, viz. 3 and 4, and one minimal element, viz. 1, which is also its least element. In mathematics , especially in order theory , a maximal element of a subset S {\displaystyle S} of some preordered set is an element of S {\displaystyle S} that is not smaller than any other element in S ...
For example, assume that we are given a serial task which is split into four consecutive parts, whose percentages of execution time are p1 = 0.11, p2 = 0.18, p3 = 0.23, and p4 = 0.48 respectively. Then we are told that the 1st part is not sped up, so s 1 = 1 , while the 2nd part is sped up 5 times, so s 2 = 5 , the 3rd part is sped up 20 times ...
