However, directional antenna based MAC protocol for software defined CR Ad-hoc networks offer great potential to reduce interference, efficiently reuse spatial spectrum, conserve node transmits power consumption, and extend directional communication range.
We develop 3D directional variance, as a quantitative biomarker of truly 3D fibrillar organization by extending the directional statistics formalism developed for describing circular data distributions (i.e. when 0° and 360° are equivalent) to axial ones (i.e. when 0° and 180° are equivalent).
Moreover, when trying to extend the directional short-time Fourier transform to distributions, (2.10) is not well defined for (finmathcal {S}'(mathbb{R}^{n})) because (g_{u,b,a}notinmathcal{S}(mathbb {R}^{n})).
In addition to the construction of global or regional geomagnetic field models, instrumental measurements were also used to extend the directional geomagnetic field variation curves derived from archeomagnetic data.
After the post-mitotic neurons are generated, they extend a directional process and migrate towards their destination, during which another MT network takes place.
The studies in this paper enrich the theories of extending limits in directional drilling and provide important guidance for design & control in actual drilling process.
In this paper, mechanical extending limits in directional drilling, which mean the maximum well depth for a certain rotary drilling system to drill under certain mechanical ground and underground constraint conditions, are systematically studied.
The calibration and registration of the four fisheye cameras is achieved by extending an existing omni-directional calibration toolbox to multi-camera calibration.
Thirdly, the mechanical extending limits for three-section directional wells under pick up and slack off operations in the sliding and rotary modes are respectively deduced and the charts of extending limits for kinds of directional wells are drawn.
Starting with the general theory established in Kanatani (1984) of describing the directional distributions of orientations, mathematical formulations have been extended to address the directional distributions of vector-valued directional data, which is the most common data type being dealt with in micromechanical investigations.
