Construction method of multi-source Dougong point cloud dataset

Abstract Dougong, a distinctive component of ancient wooden architecture, holds significant importance for the preservation and restoration of such structures. In the realm of cultural heritage preservation, the application of deep learning has gradually expanded, demonstrating remarkable effectiveness.

Development of a new method for measuring the electric field strength based on a dual electro-induction sensor

Омский научный вестник
A new method for measuring electric field strength is proposed. The method is based on the mean value measurement method, which uses a dual electroinduction spherical sensor.

Experimental evaluation of the ring focus test for X-ray telescopes using AXAF's technology mirror assembly, MSFC CDDF Project No. H20 [PDF]

A test method particularly suited for X-ray telescopes was evaluated experimentally. The method makes use of a focused ring formed by an annular aperture when using a point source at a finite distance. This would supplement measurements of the best focus

Noise Separation Technique for Enhancing Substation Noise Assessment Using the Phase Conjugation Method

Applied Sciences
The intrinsic noise of different transformers in the same substation belongs to the same type of noise, which is strongly coherent and difficult to separate, greatly increasing the cost of substation noise assessment and treatment.

Measurements of acoustic sources in motion [PDF]

Results of the far-field pressures measured from three different types of moving sources are presented. These acoustic sources consist of a point monopole, a small model jet, and an aircraft.
