A Cartesian coordinate system for human cerebral cortex
Journal of Neuroscience Methods, 2003The most commonly used method for specifying the locations of functional areas in the human cerebral cortex is the coordinate system of Talairach and Tournoux (Co-planar Stereotaxic Altas of The Human Brain (1988) Georg Thieme Verlag, Stuttgart). It was designed to locate subcortical nuclei by reference to an axis joining the anterior and posterior ...

Refinement on non-hydrostatic shallow granular flow model in a global Cartesian coordinate system
Computational Geosciences, 2016Current shallow granular flow models suited to arbitrary topography can be divided into two types, those formulated in bed-fitted curvilinear coordinates and those formulated in global Cartesian coordinates.

A Recipe for Transforming ICRS Coordinates to a Cartesian Coordinate System Centered on a Cluster
Research Notes of the AAS, 2020Abstract For the purpose of studying internal kinematics of a star cluster it is often convenient to convert the astrometric parameters of its members into cluster-centered Cartesian coordinates. I provide a detailed and rigorous derivation of such a coordinate transformation and briefly compare it with a selection of published ...

Label System on Cartesian Coordinate by Using a Digital Camera
2010 International Conference on Internet Technology and Applications, 2010a novel image-based label system is proposed in this paper, we can convert the coordinate in image into Cartesian coordinate by using an image from a single CCD camera. This system could correspond arbitrary two points on the image convert to the actual distance no matter the digital camera is vertical to the measuring plane or not and the height of ...

Spherical Convolution Matched Layer in Cartesian Coordinate System for the FDTD Solver [PDF]
2020 IEEE 3rd International Conference on Electronic Information and Communication Technology (ICEICT), 2020 Spherical truncation boundary in non-spherical coordinate system for the finite-difference time-domain (FDTD) method is discussed in this paper. The convolutional perfectly matched layer has been optimized in non-physical division and enhanced weakly ability in absorbing evanescent wave.

Study on Gradation Fractal Cartesian Coordinate System of Asphalt Mixture
Advanced Materials Research, 2013In order to explore intrinsic relation of continuous, interlocked-dense and gap gradation, this paper studied them by fractal regression analysis, by which a gradation distribution Cartesian coordinate system was established and slope of the gradation was proposed at the same time.

Crossing rules in Cartesian and standard coordinate systems
Journal of Mathematical Physics, 1986A vectorial and a tensorial crossing rule are defined in Cartesian coordinate systems. Different applications are given. With a particular choice of the standardization coefficient of vectors the same expression of dot and vector products in the standard and Cartesian coordinate systems results.

CNN‐based UGS method using Cartesian‐to‐polar coordinate transformation
Electronics Letters, 2018The main concern of user-guided segmentation (UGS) is to achieve high segmentation accuracy with minimal user interaction. A novel convolutional neural network (CNN)-based UGS method is proposed, which employs a single click as the user interaction.
