Drift Diffusion Analyses Of Preferential Choice
… problems. The models we propose are based on the drift diffusion model (DDM), which is a benchmark sequential sampling model for studying binary choice problems, is biologically plausible, and has a clear interpretation regarding optimal decision making. Chapter 1 focuses on automatic biases in …

Item parameter drift and online calibration
… and this phenomenon is termed item parameter drift. Several methods have been developed to detect drifted items, and most of the them were designed to detect drifts in the unidimensional item response model under the paper and pencil testing framework, which may not be adequate for …

Drift correction for scanning-electron microscopy
… during image acquisition, a phenomenon called drift. We propose a method for correcting drift distortion in images obtained on scanning electron and other scanned-beam microscopes by registering a series of images to create a drift-free composite. We develop a drift-distortion model for linear …

Generalized drift-diffusion for microscopic thermoelectricity
… lasers are often described with the drift-diffusion equations. We present a microscopic description of the thermoelectric effects using a generalization of the common drift-diffusion formulation of semi-classical transport. We then replicate these basic results in a commerical device …

Ultraviolet laser calibration of drift chambers
… laser as a track calibration source in drift chambers, and specifically in a small time projection chamber (TPC). Drift chambers such as TPCs reconstruct the trajectories of charged particles by amplifying and collecting electrons produced by ionization of gas atoms with which the target …

Unsupervised Concept Drift Detection in Data Streams
… stream mining, efficiently detecting concept drifts is still challenging due to the high cost of collecting true class labels. Traditional detection methods usually need high computation and memory cost and is unable to distinguish between concept drift and novelty. To improve the drift …

Drift bottle studies at Bodega Head, California
… offshore. This study describes the results of 28 drift bottle experiments performed from July 1962 to July 1963 in the Bodega Bay region. The point of release of the drift bottles in all experiments except the last three was the cove of Bodega Head about 4000 feet south of Horseshoe Cove. (This …

Performance of drift tubes under high radiation
… and the rejuvenation of an ATLAS proportional drift tube are described. Firstly, the Diethorn model of gain is tested using pressure and sense-wire voltage measurements. The drift tube was then aged using P10 gas (Ar:CH₄ 90:10) and a small amount of Si oil vapor, with a tube section of radius …

Speedway Drift: A Screenplay for an Animated Feature
… script for an animated film titled Speedway Drift. Set in the year 2064, star racer Grace Jackson is competing in an international racing tournament where she's partnered up with young newcomer Faye Sōtō in a series of dangerous obstacle courses, all while confronting memories of her …

Towards handling temporal dependence in concept drift streams.
… the problematic and prevalent issue of concept drift has produced a considerable number of methods that allow online classifiers to adapt to changes in the stream distribution. However, recent research suggests that the presence of temporal dependence can cause misleading evaluation when …

Iron-Cemented Drift in Logan County, North Dakota
… indurated-limonite-goethite cemented glacial drift. The writer believes the origin of the cementing material to be similar to that of most bog-iron ores, and that this cement accumulated during a pre-Wisconsin interglacial age. </p><p>The glacial drift directly overlying the iron-cemented …

Snap-drift neural computing for intelligent diagnostic feedback
… and misconceptions. Previously, a snap-drift modal learning neural network has been applied to improve the feedback mechanisms of computer-based formative assessments. This study investigated the application of snap-drift modal learning neural network for analysing student responses to a …
