GörlitzFor small . the Hankel determinants .(.) of the sequence . are easy to guess and show an interesting modular pattern. For arbitrary . and . no closed formulae are known, but for each positive integer . the special values .(.), .(. + 1), and . have nice values which are proved in this paper.

Cylinders and Struts, considerable amount of information relating to the design of pressure vessels exists, and in many cases the designer would be well advised to consult the available sources.. For simple cylinder designs, however, in which pressures are relatively low and temperatures around normal, the formulae given here will prove helpful.

Standard Components, and structures invariably contain components which are common to more than one design. It is only to be expected, therefore, that for reasons of economy, interchangeability and safety such parts will be standardised where possible.

Robert SteeleDie Turing-Maschine wird vorerst mit Hilfe eines physikalischen Modells beschrieben. Es folgt eine genauere Beschreibung durch mengentheoretische Begriffe. Dabei wird jeder Turing-Maschine eine n-stellige Funktion zugeordnet.

On the Correlation Between Charpy Notch Toughness and Fracture Toughness of Base and Weld MetalThe Charpy test has been used since the beginning of the century (1905) for qualitative assessments of the brittle-to-ductile transition temperature (range) of structural steels.
