Autogenous self‐healing of concrete: Experimental design and test methodsA review
Engineering Reports, Volume 5, Issue 1, January 2023., 2023 Concrete exhibits an intrinsic ability to heal cracks, defined as “autogenous self‐healing.” However, despite code restrictions, autogenous self‐healing of concrete shows limited effectiveness in practice. This indicates the need for further research to provide engineers with reliable design rules.

Application of Hilbert instantaneous spectrum on improved bolt anchoring quality detection
Engineering Reports, Volume 4, Issue 12, December 2022., 2022 A method utilizing a way to compute the instantaneous frequency curve of the bolt signal is proposed to overcome the phase folding problem existing in the Hilbert transform spectrum. The instantaneous frequency curve of the signal can help accurately identify the reflected signal from the bolt bottom and the position of the defect, thus accurately ...

Local and global low-regularity solutions to generalized Leray-alpha equations
Electronic Journal of Differential Equations, 2015 It has recently become common to study approximating equations for the Navier-Stokes equation. One of these is the Leray-alpha equation, which regularizes the Navier-Stokes equation by replacing (in most locations) the solution u with $(1-\alpha^2 ...

Advanced Electronic Materials, EarlyView.Revisited Black‐body radiation formula accounting for nonuniform temperature is proposed for calibration of planar thermal light sources. Calibration of optical power is based on measurement of the highest and lowest temperatures. Abstract Miniature and low‐cost light sources are highly desirable for numerous optical microsystems.
