T. O. Engset
Encyclopedia
Tore Olaus Engset was a Norwegian
mathematician and engineer who did pioneering work in the field of telephone traffic queuing theory
.
Engset got a M.Sc. in physics and mathematics (1894) at University of Oslo
, after which he
worked at Televerket
as office worker, traffic analyst and later director general
(1921-22, 1930-35).
He developed the Engset formula (1915) before the breakthroughs of
A. K. Erlang (1917). His 1915 manuscript "Om beregningen av vælgere i et automatisk telefonsystem" (1915) was not, however, published until 1918. That work was translated to German as "Die Wahrscheinlichkeitsrechnung zur Bestimmung der Wählerzahl in automatischen Fernsprechämtern", in Elektrotechnische Zeitschrift, Heft 31, 1918. An English translation appeared in Arne Myskja, "On the Calculation of Switches in an Automatic Telephone System" in Telektronikk, 94(2):99-142, 1998.
He also published a work on nuclear physics
(1927): "Die Bahnen und die Lichtstrahlung der Wasserstoffelektronen. Ergänzende Betrachtungen über Bahnformen und Strahlungsfrequenzen" (3 parts) in Annalen der Physik
, 82 (1927) 1017; 83 (1927) 903; 84 (1927) 880.

Queueing theory
Queueing theory is the mathematical study of waiting lines, or queues. The theory enables mathematical analysis of several related processes, including arriving at the queue, waiting in the queue , and being served at the front of the queue...

Nuclear physics
Nuclear physics is the field of physics that studies the building blocks and interactions of atomic nuclei. The most commonly known applications of nuclear physics are nuclear power generation and nuclear weapons technology, but the research has provided application in many fields, including those...
