Angular Deviation in Directional Receiver Correlation

The Journal of the Acoustical Society of America, 1960
When the axes of two directional pressure gradient receivers providing inputs to a steerable correlator receiving system deviate from the desired broadside direction, the system output is altered. An analysis of the improvement in output signal-noise ratio shows that, in general, the maximum improvement decreases, the direction of maximum improvement ...

Large deviations and moderate deviations for kernel density estimators of directional data

Acta Mathematica Sinica, English Series, 2010
Let \(f_n\) be the non-parametric kernel density estimator of directional data based on a kernel function \(K\) and a sequence of iid random variables taking values in the \(d\)-dimensional unit sphere \(S^{d-1}\). This paper studies uniform large deviations and uniform moderate deviations for \(f_n\) by the empirical process approach.

Factors that Influence Direction Deviation in Freehand Implant Placement

Journal of Prosthodontics, 2019
AbstractPurposeThis retrospective study investigates the accuracy of freehand implant placement and whether the factors of presence of an adjacent tooth, implant quadrant, number of missing teeth, and location of the implant site influence direction and angulation deviations.Materials and MethodsAccording to specific inclusion and exclusion criteria, a

Deviations from Schmid’s Law in Uni-Directional Strain

Physica Status Solidi (a), 1978
The various causes for deviations from schmid's law are examined theoretically. The by far largest contribution to such deviations is found to be due to the Peierls-Nabarro force via the “breathing” of the dislocations core volumes in their motion over Peierls hills and valleys.

Direct measurement method for plumb line deviations

Measurement Techniques, 2010
The effect of irregularities of the refractive index of a terrestrial layer of the atmosphere on the slope of the polarization plane of an electromagnetic wave is evaluated numerically. An optical range polarimeter is developed having a sensitivity of the order of 1″. The possibility is demonstrated of practical application of the polarization plane as

Deviation Analysis and Correction of Direction Control for Horizontal Directional Drilling Crossing

ICPTT 2011, 2011
Crossing by Horizontal Directional Drilling (HDD), characterized by short construction period, high quality and little impact on environment, is widely used in pipeline crossing engineering. Deviation between the practical and theoretical exit point, where the bit unthreads, is difficult to control. Excessive deviation could not only cause unconformity

Detection of direction deviation of vehicle using CCTV cameras

International Conference on Recent Advances and Innovations in Engineering (ICRAIE-2014), 2014
As an application of CCTV Traffic surveillance, detection of direction deviation of vehicle is an important dimension, which demands an intelligent solution. It is assumed that images of vehicles have been captured at a particular orientation i.e. from top view and top-front view using CCTV cameras installed at junction along a particular road at an ...

Vectorial statistics for the standard deviation of wind direction

Meteorology and Atmospheric Physics, 2016
The standard deviation of wind direction is an important parameter in atmospheric pollution management. It can be used to calculate the rate of horizontal diffusion and from this the transport and dispersion of air contaminants can be determined. The standard deviation of wind direction cannot be calculated directly from customary linear statistics ...
