A survey of two-dimensional graph layout techniques for information visualisation [PDF]

, 2012
Many algorithms for graph layout have been devised over the last 30 years spanning both the graph drawing and information visualisation communities. This article first reviews the advances made in the field of graph drawing that have then often been ...

Techno-Economic Analysis of Central Receiver Plants According to the Optical Error of the Solar Field

SolarPACES Conference Proceedings
Among the concentrated solar power technologies (CSP), the central receiver (CR) technology is the most promissing to achieve the lowest levelized cost of energy (LCOE) and the one expected to play one of the major roles in the energetic mix in the next

On the Design of Recuperator for Transcritical Cycle Adopting CO2‐Based Mixture as Working Fluid: A Focus on Transport Properties Prediction

Energy Technology, Volume 12, Issue 1, January 2024.
CO2 binary mixtures in transcritical power cycles offer efficiency improvements compared to sCO2 in hot‐environments, but no studies on transport properties are available for complex/asymmetric CO2 mixtures. This work proves that the friction theory model, calibrated on pure component data, has superior predictivity compared to traditional models.

Comparing Study of Biomimetic Spiral and Radial Staggered Layouts of the Heliostat Field

Energy Procedia, 2015
AbstractThe radial staggered layout is classical and convenient which has almost been adopted by all the researchers while the biomimetic spiral layout is recommended in recent years, which has some obvious advantages and is promising to be demonstrated in real plant. However, the specific relationship between these two layouts is unknown.
