Development and Research of a Promising Pumpless Liquid Cooling System for Reciprocating Compressors
Energies, 2023 A new pumpless liquid cooling system for a single-stage two-cylinder reciprocating compressor has been developed from the analysis of work processes and cooling systems of reciprocating compressors, where one piston compresses and moves gas and coolant ...

Mixture of volumetric primitives for efficient neural rendering [PDF]
ACM Transactions on Graphics, 2021 Real-time rendering and animation of humans is a core function in games, movies, and telepresence applications. Existing methods have a number of drawbacks we aim to address with our work. Triangle meshes have difficulty modeling thin structures like hair, volumetric representations like Neural Volumes are too low-resolution given a reasonable memory ...

The Influence of Radial and Axial Gaps on Volumetric Efficiency of External Gear Pumps
Energies, 2021 The design of gear pumps and motors is focused on more efficient units which are possible to achieve using advanced numerical simulation techniques. The flow that appears inside the gear pump is very complex, despite the simple design of the pump itself.

Efficient skeletonization of volumetric objects [PDF]
IEEE Transactions on Visualization and Computer Graphics, 1999 Skeletonization promises to become a powerful tool for compact shape description, path planning, and other applications. However, current techniques can seldom efficiently process real, complicated 3D data sets, such as MRI and CT data of human organs.

Efficient Volumetric Segmentation Method [PDF]
Annals of Computer Science and Information Systems, 2014 In this paper we extend our previous work for planar images by adding a new step in the volumetric segmentation algorithm that allows us to determine regions closer to it. There are huge of papers for planar images and segmentation methods and most of them are graph-based for planar images and very few papers for volumetric segmentation methods ...
