Full-Frame Transform Coding of Cross-Sectional Images
SPIE Proceedings, 1989Image compression algorithms based on full-frame discrete transforms completely eliminate the artifacts generated by block quantization techniques. Previously, we have shown that full-frame compression using an adaptive two-dimensional bit-allocation table is capable of achieving compression ratios as high as 10:1 to 20:1, while maintaining excellent ...

Rigorous determination of cross sections via complex transformations
International Journal of Quantum Chemistry, 2009General formulas useful in the context of probability-amplitude calculations are given in terms of the appropriately deformed resolvent expressions. It is proven that the formulation based on the skew inner projections leads to a series of approximations for the dilated resolvent, convergent in the limit to the exact result.

Cross-sectional area measurement in collapsed tubes using the transformer principle
Medical & Biological Engineering & Computing, 1989To avoid the necessity for intraluminal catheters as used with the axial impedance method of measuring the cross-sectional area of flexible tubes independently of their shape, while retaining the advantage of an immediate electrical output, an electromagnetic method was tested.

Naturally Ordered Transformation Semigroups Preserving an Equivalence Relation and a Cross-section
Algebra Colloquium, 2011The paper is concerned with the so-called natural order on the semigroup [Formula: see text], where [Formula: see text] is the full transformation semigroup on a set X, E is a non-trivial equivalence on X and R is a cross-section of the partition X/E induced by E. We determine when two elements of TE(X,R) are related under this order, find elements of

On cross section transformations in reactions with three outgoing fragments
Nuclear Instruments and Methods in Physics Research, 1982Some cross section transformation problems are treated which occur in coincidence measurements on nuclear reactions with three fragments in the exit channel. Expressions are given for the transformation from the coordinates of two fragments to the coordinates of their relative and centre-of-mass motion. The influence of constraints, for instance on the

Journal of Nursing Management, 2021
The purpose of this research was to explore nurses' mentorship, mentors' basic psychological needs satisfaction and transformational leadership. Moreover, this study evaluated the moderating role of a protégé's mindfulness.Previous research had only focused on the benefits that protégés reaped from the mentoring relationship, neglected the mentor's ...

Mode Transformers on Longitudinal Diaphragms in Waveguides of Complex Cross Section
2007 International Kharkiv Symposium Physics and Engrg. of Millimeter and Sub-Millimeter Waves (MSMW), 2007In this work the technique of longitudinal diaphragms is applied to MWT design based on four-ridge rectangular waveguides. The physical basis of mode transformation is discussed, the process of transformation of one propagating mode of the waveguide to another on different steps of the device is illustrated.

Form-Invariance of Maxwell's Equations in Waveguide Cross-Section Transformations
Electromagnetics, 2009Abstract We present a novel coordinate transformation technique that controls the propagation of waves inside a waveguide, such that the waveguide behaves as if it is a “reshaped” waveguide. In this technique, the spatial domain of the waveguide is mapped to that of its reshaped equivalent, yielding an anisotropic medium inside the waveguide.

Interpretation of a dynamic radar cross-section using the wavelet transform
International Journal of Electronics, 1995The wavelet analysis technique is applied to obtain instantaneous time-frequency information from dynamic radar cross-section data, since the dynamic electromagnetic backscattered signals contain both time and frequency information. The multiresolution property of the wavelet transform (WT) is well suited to analysing such time-varying signals ...

Geometrical transformation of bodies of arbitrary cross-section for numerical computation
Digest on Antennas and Propagation Society International Symposium, 2003A mode discretization approach is used to study objects of arbitrary cross section but having certain planes of symmetry. To investigate such a geometry the cross section of the object is conformally transformed into a new space which eliminates the existing discontinuities of the object's cross section.
