The Points of Concurrence Theory in Guidobaldo del Monte’s Scenography
Published 2018-12-01“…The treatise elaborates a scientific method of universal validity to construct scenes, based on the theory of the points of concurrence explained in the first book of this work, a theory that deeply influenced the history of perspective and descriptive geometry. In Guidobaldo’s work, the problem of controlling the projective transformations of space is resolved by reducing the relief perspective to a set of flat perspectives in relation to each other and controlled through the theory of points of concurrence. …”

Regular Analysis of Aero-Diesel Piston Engine between Combustion Chamber Size and Emission
Published 2019-01-01“…The results show that reducing appropriately the reentrant-max diameter ratio and max diameter-max depth ratio of the combustion chamber can reduce emissions when maintaining the same compression ratio by adjusting the mid-depth. Modifying the geometry parameters of the combustion chamber to verify regularity, it was found that engine NOx emission decreased by 28% and soot emission decreased by 3.6% when changing the size, which verified the correctness of regular analysis.…”

Theoretical Model for the Performance of Liquid Ring Pump Based on the Actual Operating Cycle
Published 2017-01-01“…With the major geometric parameters and operating conditions of a liquid ring pump, the performance parameters such as the actual capacity for suction and discharge, shaft power, and global efficiency can be conveniently predicted by the proposed theoretical model, without the limitation of empiric range, performance data, or the detailed 3D geometry of pumps. The proposed theoretical model was verified by experimental performances of liquid ring pumps and could provide a feasible tool for the application of liquid ring pump.…”

Semiclassical quantization of M5 brane probes wrapped on AdS3 × S 3 and defect anomalies
Published 2025-01-01“…Abstract We consider two supersymmetric M5 brane probe solutions in AdS7 × S 4 and one in AdS4 × S 7 that all have the AdS3 × S 3 world-volume geometry. The values of the classical action of the first two M5 probes (with S 3 in AdS7 or in S 4) are related to the leading N 2 parts in the anomaly b-coefficient in the (2,0) theory corresponding to a spherical surface defect in symmetric or antisymmetric SU(N) representations. …”
