Measurement of integral non-linearity (INL) and differential non-linearity (DNL) of an A/D converter using the histogram method incurs large test time. This test time can be a significant percentage of the total test time, especially for high resolution and low sampling-speed A/D converters. This paper describes a test methodology for measuring the INL and DNL specifications of A/D converters b...

Abstract The diagonal inerter is integrated into a suspension vibration reduction system (SVRS). dynamic model of the SVRS with and damping established. strong geometric nonlinearity. retaining non-linearity up to cubic terms validated under impact excitation. conditions omitting static deformation are determined. effects on performance explored random excitations. proposed both better than tha...

This paper explores buildability quantification of randomly meshed 3D printed concrete objects by considering structural failure elastic buckling. The newly proposed model considers the most relevant printing parameters, including time-dependent material behaviors, velocity, localized damage and influence sequential process. computational uniaxial compression tests were first conducted to calib...

Introduction: In recent years, the use of magnetic resonance (MR) images in radiation treatment planning has drawn considerable attention. However, although the extent of a tumor can be determined in great detail on MR images, the geometric accuracy of these images is limited by distortions stemming from the inhomogeneity of the static background magnetic field, the nonlineari...

A new geometric approach for nonlinear independent component analysis (ICA) is presented in this paper. Nonlinear environment is modeled by the popular post nonlinear (PNL) scheme. To eliminate the nonlinearity in the observed signals, a novel linearizing method named as geometric post nonlinear ICA (gpICA) is introduced. Thereafter, a basic linear ICA is applied on these linearized signals to ...

We propose and analyze a new way for obtaining an adiabatic geometric phase for light, via the sum-frequency-generation nonlinear process. The state of light is represented by the complex amplitudes at two different optical frequencies, coupled by the second order nonlinearity of the medium. The dynamics of this system is then shown to be equivalent to that of a spin-1/2 particle in a magnetic ...

Control of permanent magnetic actuators is not an easy task because of the presence of the nonlinear quadratic terms of the currents. In order to achieve a suitable controlled dynamics canceling the effect of the nonlinearity, a new control strategy has been conceived. The proposed strategy combines the geometric eigenvector concept through a pre-compensation action and a Model Predictive Contr...

In a recent paper Abramowicz and Kluźniak [1] have discussed the problem of epicyclic oscillations in Newton’s and Einstein’s dynamics and have shown that Newton’s dynamics in a properly curved three-dimensional space is identical to testbody dynamics in the three-dimensional optical geometry of Schwarzschild spacetime. One of the main results of this paper was the proof that different behaviou...

The paper deals with the interaction between buckling and resonance instabilities of mechanical systems. Taking into account the effect of geometric nonlinearity in the equations of motion through the geometric stiffness matrix, the problem is reduced to a generalized eigenproblem where both the loading multiplier and the natural frequency of the system are unknown. According to this approach, ...

In this paper we consider a representative a priori unstable Hamiltonian system with 2 + 1/2 degrees of freedom, to which we apply the geometric mechanism for diffusion introduced in the paper Delshams et al., Mem. Amer. Math. Soc. 2006, and generalized in Delshams and Huguet, Nonlinearity 2009, and provide explicit, concrete and easily verifiable conditions for the existence of diffusing orbit...
