On SETAR non- linearity and forecasting [PDF]

We consider the usefulness of the two-regime SETAR model for out-of-sample forecasting, and compare it with a linear AR model. A range of newly-developed forecast evaluation techniques are employed.

Higher order non-linear effects in a Josephson parametric amplifier

, 2015
Non-linearity of the current-phase relationship of a Josephson junction is the key resource for a Josephson parametric amplifier (JPA), the only device in which the quantum limit has so far been achieved at microwave frequencies.

Buckling of Steel Portal Frames Considering Material Non-Linearity

Diyala Journal of Engineering Sciences, 2015
In this research, an experimental study was carried out to investigate the failure modes of eight frames with IPE cross-sections. The study was conducted by subjecting these frames to two equal concentrated loads (applied directly on columns); however ...

Correcting the Non-Linear Response of Silicon Photomultipliers

Sensors
The finite number of pixels in a silicon photomultiplier (SiPM) limits its dynamic range to light pulses up to typically 80% of the total number of pixels in a device.

The Equivalent Gain Matrix of a Multivariable Non-Linearity

Measurement + Control, 1969
The equivalent gain concept of a mono-variable non-linear stochastic process is used to evaluate the linear matrix equivalent of a multi-variable non-linearity having n independent inputs and m outputs.

Reducing sample variance: halo biasing, non-linearity and stochasticity [PDF]

, 2010
Comparing clustering of differently biased tracers of the dark matter distribution offers the opportunity to reduce the cosmic variance error in the measurement of certain cosmological parameters. We develop a formalism that includes bias non-linearities

Giant Optical Non-linearity induced by a Single Two-Level System interacting with a Cavity in the Purcell Regime

, 2007
A two-level system that is coupled to a high-finesse cavity in the Purcell regime exhibits a giant optical non-linearity due to the saturation of the two-level system at very low intensities, of the order of one photon per lifetime. We perform a detailed

Light Readout of Small Scintillators Using SiPM Photosensors

Sensors
During the last two decades, relevant progress has been achieved in silicon photomultiplier (SiPM) technology, such that in an increasing number of radiation detection applications they are proposed as a viable alternative to traditional photomultiplier ...
