Parallel Implementation of Katsevich's FBP Algorithm

International Journal of Biomedical Imaging, 2006
For spiral cone-beam CT, parallel computing is an effective approach to resolving the problem of heavy computation burden. It is well known that the major computation time is spent in the backprojection step for either filtered-backprojection (FBP) or ...

A parallel in time/spectral collocation combined with finite difference method for the time fractional differential equations

Journal of Algorithms & Computational Technology, 2021
In this article, we consider the numerical solution for the time fractional differential equations (TFDEs). We propose a parallel in time method, combined with a spectral collocation scheme and the finite difference scheme for the TFDEs.

Parallel Computing of Numerical Simulation in Building Fires

Journal of Computers, 2012
Fire Dynamics Simulator parallel computing program has been compiled based on Message Passing Interface. The fire flow field is divided into several segments and each segment is allocated to the corresponding node to calculate. The calculation shows that computing time has been significantly reduced as the amount of processors increase.

Parallel Solution Algorithm for the Multi-Group Particle Transport Equations on the Unstructured Meshes

Journal of Algorithms & Computational Technology, 2010
The numerical simulations for solving the transport equations lead to the large computation and need to implement parallel calculation. On the unstructured grids, the communicating delays, sorting algorithms and inserting algorithms limit the performance

Forward kinematics for 6-UPS parallel robot using extra displacement sensor

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
Many assembly modes exist due to multi-solutions for forward kinematics of 6-UPS parallel robot. However, the existing theoretical research results have not been well applied to the real-time control, because of the complexity of the forward kinematics ...

CUDA-Based Particle Swarm Optimization in Reflectarray Antenna Synthesis

Advanced Electromagnetics, 2020
We show how reflectarray antenna synthesis can take profit from parallel computing on Graphics Processing Units (GPUs). The presented approach uses an implementation of Particle Swarm Optimization in CUDA language and accelerates the computation of the ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
