When computing integral curves and integral surfaces for large-scale unsteady flow fields, a major bottleneck is the widening gap between data access demands and the available bandwidth (both I/O and in-memory). In this work, we explore a novel advection-based scheme to manage flow field data for both efficiency and scalability. The key is to first(More)
The exploration of geological composition, e.g. underground flow path, is a significant step for oil and gas search. However, to extract the structural geological composition from the volume, neither the classic volume exploration methods, e.g. transfer function design, nor the traditional volume cut algorithms can be directly used due to its three natural(More)
prepared and the high-temperature electrical and thermal transport properties are investigated systematically. Lattice constants of RFe 4 Sb 12 increase almost linearly with increasing the ionic radii of the fillers, while the lattice expansion in filled structure is weakly influenced by the filler valence charge states. Using simple charge counting, the(More)
Most of the existing approaches to visualizing the vector field ensembles are achieved by visualizing the uncertainty of individual variables of different simulation runs, for example, geometry distance, statistics, variability etc. However, the comparison of the derived feature or user-defined feature (e.g. vortex) is also of vital significance since they(More)
This paper has designed a set of industrial raw material automatic discharging devices based on PLC(Programmable Logic Controller). The details of design device were described. Its design is divided into the theory design, the peripheral device structure design, the circuit design, the controller software design, design of mechanism and so on. According to(More)
A three-dimensional numerical model is proposed to determine the pressure drops in porous media consisting of obstacles of different sizes. A series of full three-dimensional numerical calculations were performed to reveal complex three-dimensional velocity and pressure fields within three-dimensional porous structures consisting of spheres of different(More)
Vehicle count is increasing by the day in urban area. Vehicle detection plays an important role in road traffic applications. By using vehicle detection methods different traffic parameters such as vehicle speed, density, volume, traffic flow rate, travelling time, congestion level can be calculated and these methods can be applied for vehicle tracking,(More)
The computer aided imaging technique is used to study the beamforming of acoustic radiation force excitation, including the different frequency (includes interlaced, entered, symmetrically separated), impulse, and amplitude modulated patterns. The research aims to model and design an ultrasound system with suitable acoustic radiation force excitation, with(More)
