Sentence examples for frf in from inspiring English sources

Unknown parameters (mainly spring-damper pairs) in a physically parameterized nonlinear dynamic model are identified in the frequency domain, using estimates of the nonparametric frequency response function (FRF) in different robot configurations/positions.

Later, an optimization process based on this formulation that involves the joint properties as design variables has been developed in order to identify the joint parameters that improve the adjustment between numerical and experimental FRF in the case of harmonic excitations.

In the case WRC, FRF in x direction is equal to FRF of the second mode.

Although well below the US and the EU in overall R&D funding, FRF in China has had a sustainable and high growth rate vs. stagnation in the US and the EU. 7. The EU currently produces more science and engineering doctoral graduates and scientific publications than the US in absolute terms, but not per capita.

Streptozotocin significantly reduced cell viability, which was protected against by the co-presence of FRF in a dose-dependent mode.

Models of two possible conformations (A and B) of Arg in the P1 position of the substrate FRF in the active site of human cathepsin L (3OF8) [ 33 ].

38 The increase in FRF rates in MA driven by Caucasians and non-Hispanics is in contrast to the racial differences observed in violent deaths with non-Hispanic African-Americans having the highest rate of 21.6 as compared with 4.9 among Caucasians.

A Local Rational Method LRMM) is employed to obtain multivariable Frequency Response Functions (FRFs) in a single experiment.

To avoid the use of excessive FRFs in the formulation, a procedure to study each joint independently is developed, where an appropriate number of connection points in the contact areas between the rails and the carriages is determined.

The aim of the research described in this article is to propose a technique for curve-fitting a modal model to frequency response functions (FRFs) in order to deal with multi-input multi-output (MIMO) systems with highly coupled modes, usually encountered in vibration testing.

Such problems may be circumvented by restricting the experimental database to point FRFs; in this case, the procedure is quite robust and excellent results are obtained, although it is necessary to plan experimental testing differently from the usual modal testing, with possible impact on related costs.
