Habibie had known Hasri Ainun in childhood, junior high school and in senior high school at SMA Kristen Dago (Dago Christian Senior High School), Bandung. The two married on 12 May 1962, returning to Germany shortly afterwards. [21] Habibie and his wife settled in Aachen for a short period before moving to Oberforstbach. In May 1963 they had a ...
Habibie's memorial in Gorontalo, he is remembered as the prominent figure in Indonesian science and technology, especially in aeronautics sector. B. J. Habibie, German-trained professor in aerospace engineering. Produced theories known as the Habibie Theorem, Habibie Factor, and Habibie Method. Later he became the third president of Indonesia.
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.
Goldschmidt's tolerance factor (from the German word Toleranzfaktor) is an indicator for the stability and distortion of crystal structures. [1] It was originally only used to describe the perovskite ABO 3 structure , but now tolerance factors are also used for ilmenite .
Before choosing a formula it is worth knowing that in the paper on the Moody chart, Moody stated the accuracy is about ±5% for smooth pipes and ±10% for rough pipes. If more than one formula is applicable in the flow regime under consideration, the choice of formula may be influenced by one or more of the following: Required accuracy
The four-factor formula, also known as Fermi's four factor formula is used in nuclear engineering to determine the multiplication of a nuclear chain reaction in an infinite medium. Four-factor formula: k ∞ = η f p ε {\displaystyle k_{\infty }=\eta fp\varepsilon } [ 1 ]
The ideality factor typically varies from 1 to 2 (though can in some cases be higher), depending on the fabrication process and semiconductor material. The ideality factor was added to account for imperfect junctions observed in real transistors, mainly due to carrier recombination as charge carriers cross the depletion region .
In atomic physics, the Landé g-factor is a multiplicative term appearing in the expression for the energy levels of an atom in a weak magnetic field. The quantum states of electrons in atomic orbitals are normally degenerate in energy , with these degenerate states all sharing the same angular momentum.
