Punching shear in flat slab systems – Experimental quantification of unconsidered system influences

Structural Concrete, EarlyView.
Abstract Due to the demand for slender and functional buildings, flat slabs are a frequently used load‐bearing element in buildings. However, the concentrated load introduction at the slab‐column connection is often the governing detail in design due to punching shear failure.

Time‐Domain Computation of Propagation Characteristics of Partial Discharge in Cross‐Linked Polyethylene High‐Voltage Cable Incorporating Modified Frequency‐Dependent Parameters

High Voltage, EarlyView.
ABSTRACT The propagation characteristics of partial discharge (PD) in cables impact PD detection sensitivity, defect localisation accuracy and defect severity evaluation. Currently, the effects of semiconducting materials' frequency‐dependent properties and corrugated aluminium sheath structures on PD signal propagation in high‐voltage (HV) cables ...

A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

High Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Radiation of piezoelectric rings into the air through cylindrical waveguides

Archives of Acoustics, 2014
In the paper the results of the investigations of the radiation of piezoelectric rings into the air through solid (e.g. glass, plexiglass, aluminium) cylinders are presented. The obtained radiation patterns approximate Bessel distribution. In the case of

Anisotropy in Dry‐Type Valve‐Side Bushings of Converter Transformer: Phenomena and Effects

High Voltage, EarlyView.
ABSTRACT The safe and stable working of dry‐type valve‐side bushings, important components of converter transformers, is essential. In recent years, poor design has led to several core breakdown, flashover and cracking failures. The bushing cores, composed of crepe paper and aluminium foil, exhibit significant anisotropic physical properties due to its

Efficient computation of Fourier–Bessel transforms for transverse-momentum dependent parton distributions and other functions

European Physical Journal C: Particles and Fields
We present a method for the numerical computation of Fourier–Bessel transforms on a finite or infinite interval. The function to be transformed needs to be evaluated on a grid of points that is independent of the argument of the Bessel function.

Denoising framework for X‐ray absorption spectroscopy data

Journal of Synchrotron Radiation, EarlyView.
We introduce a high‐performance Python‐based XAS denoising package called XASDenoise, which implements our newly developed stationarity warping method and advanced denoising techniques based on Gaussian process regression and a convolutional autoencoder.X‐ray absorption spectroscopy (XAS) is a powerful tool for probing the structural and electronic ...

Regional cerebellar structural deficits distinguish psychostimulant‐free ADHD youth with and without familial risk for bipolar I disorder: a cross‐sectional morphometric analysis

Journal of Child Psychology and Psychiatry, EarlyView.
Background Although attention‐deficit/hyperactivity disorder (ADHD) with familial risk for bipolar I disorder (BD) may represent a more severe illness conferring greater risk for developing BD, associated neurostructural substrates remain poorly understood.

Source inverse problem for fractional kinetic equation

Математичні Студії
We study the Cauchy problem for fractional kinetic equation in spaces with values in the entire scale of spaces of Bessel potentials, prove its unique, classical in time, solvability, obtaining an analogue of the maximum regularity of the solution ...

The Diremption of Meaning

Modern Theology, EarlyView.
Abstract Examining work by Rowan Williams, this essay explores what he often refers to as the ‘difficulty’ of writing theology. The difficulty of theology lies in engaging the ruse of having ultimate answers to ultimate questions. The stakes are high: ‘God‐talk’ must concern itself with truth, with reality.
