The classical limit of quantum q-oscillators suggests an interpretation of the deformation as a way to introduce non linearity. Guided by this idea, we considered q-fields, the partition fumction, and compute a consequence on specific heat and second order correlation function of the q-oscillator which may serve for experimental checks for the non linearity.

As the performance of Analog-to-Digital Converters continues to improve, it is becoming more challenging and costly to develop sufficiently fast and low-drift signal generators that are adequately more linear than the ADC for the purpose of linearity testing. This work relaxes the linearity requirements on the signal generators used for ADC testing by alternatively employing multiple non-linear...

Determining how monetary policy makers react to changes in key economic variables has been of major interest to monetary economists. Estimates of monetary policy rules (reaction functions) are a widely used method for doing this. Behavior differs under different policy regimes, as in rule-based systems or chronic inflation. In practice, estimates of instrument rules have been used to descri...

Many color digital camera systems exhibit a non-linearity between the input intensity and the output response of the color channels. Although the sensor (CCD) material responds to light intensity in a linear way a non-linearity is often added by the camera manufacturer. Recent research has highlighted that in order to be able to estimate this nonlinearity (sometimes termed gamma) it is necessar...

In this article, we present a low-power digital phase-locked loop (PLL)-based phase modulator targeting low error vector magnitude (EVM). We introduce new non-uniform clock compensation (NUCC) scheme to tackle an EVM degradation resulting from the beneficial use of time-varying sampling that is re-timed phase-modulated carrier. also employ phase-domain predistortion (DPD) combat intrinsic non-l...

Delamination fracture of a two-dimensional functionally graded multilayered four-point bending beam that exhibits non-linear behaviour of the material is analyzed. The fracture is studied analytically in terms of the strain energy release rate. The beam under consideration has an arbitrary number of layers. Each layer has individual thickness and material properties. A delamination crack is loc...

A remarkable non-linearity was found between dose and transfection activities of non-viral gene delivery systems, such as a Lipofectamine/DNA complex and an octaarginine-modified multifunctional envelope-type nano device (R8-MEND). We measured the nuclear delivery of pDNA to distinguish the non-linearity in intracellular pharmacokinetics or pharmacodynamics after transfection with R8-MEND at di...

In this work, a non-iterative identification approach is presented for estimating a single-input single-output Wiener model, comprising an infinite impulse response discrete transfer function followed by static non-linearity. Global orthogonal basis functions and orthogonal Hermite polynomials are used as expansion bases for the linear subsystem and the non-linearity, respectively. A multi-inde...

In regression analysis, non-linearity in fixed and random effects can adversely affect efficiency of regression parameter estimates. Successful non-linear time series modeling would improve regression parameter estimates and produce a richer notion of water quality than linear time series models allow. In addition multiple independent variables make each point in space a finite dimensional vect...
