Rocketdyne LOX bearing tester program [PDF]

open access: yes
The cause, or causes, for the Space Shuttle Main Engine ball wear were unknown, however, several mechanisms were suspected. Two testers were designed and built for operation in liquid oxygen to empirically gain insight into the problems and iterate ...

Toolbox for continuous variable entanglement production and measurement using spontaneous parametric down conversion

open access: yes, 2015
We provide a toolbox for continuous variables quantum state engineering and characterization of biphoton states produced by spontaneous parametric down conversion in a transverse pump configuration.

Type inference for Python programming language

open access: yesТруды Института системного программирования РАН, 2018
The article presents type inference for programs written in Python programming language. At first, type inference algorithms for parametric polymorphism that were described in the scientific literature are reviewed.

Blue-light induced infrared absorption in KNbO3 [PDF]

open access: yes, 1994
We have used a high-finesse cavity to measure the cw intensity dependence and dynamics of blue-light-induced infrared absorption (BLIIRA) in KNbO3 crystals for blue-light intensities between 7 x 10^-4 and 2 x 10^4 W/cm^2.

The Effect of Mechanical Resonance on Josephson Dynamics

open access: yes, 2011
We study theoretically dynamics in a Josephson junction coupled to a mechanical resonator looking at the signatures of the resonance in d.c. electrical response of the junction.

The Oka principle for sections of subelliptic submersions

open access: yes, 2001
Let X and Y be complex manifolds. One says that maps from X to Y satisfy the Oka principle if the inclusion of the space of holomorphic maps from X to Y into the space of continuous maps is a weak homotopy equivalence. In 1957 H.

Statistics of radiation at Josephson parametric resonance

open access: yes, 2011
Motivated by recent experiments, we study theoretically the full counting statistics of radiation emitted below the threshold of parametric resonance in a Josephson junction circuit.

Improved non‐cascaded continuous‐set model‐free predictive control scheme for PMSM drives

open access: yesIET Power Electronics
This article presents an improved multiple‐step model‐free predictive control (MS‐MFPC) method for permanent magnet synchronous motor (PMSM) drives. Specifically, a reduced‐order MS‐MFPC based on an ultra‐local model, which employs only the input and ...

Semiclassical expansion of parametric correlation functions of the quantum time delay

open access: yes, 2006
We derive semiclassical periodic orbit expansions for a correlation function of the Wigner time delay. We consider the Fourier transform of the two-point correlation function, the form factor $K(\tau,x,y,M)$, that depends on the number of open channels ...
