Reduced area approach for predicting punching shear resistance of biaxial hollow slabs with openings

Results in Engineering, 2023
Due to the inclusion of hollow plastic spheres in bubbled slab systems, the shear resistance is greatly reduced. Also, the existence of the opening in the vicinity of columns takes away part of the concrete responsible for resisting shear forces and ...

Boosting the Energy Density Through In Situ Thermal Gelation of Polymer Electrolyte with Lithium‐Graphite Composite Anode

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Figures a–b and c–d present the ToF‐SIMS results of the Li metal and polymer electrolyte interface before and after cycling, respectively. After cycling, accumulation of S− and LiF− components at the interface was observed, confirming the formation of an artificial SEI layer. We have entered the age of renewable energy revolution.

Determining the potential use of biosurfactants in preventing endodontic infections

European Journal of Oral Sciences, Volume 130, Issue 6, December 2022., 2022
Abstract Microbial biofilms play a dominant role in the failure of endodontic therapies. Bacterial adhesion is the first step in the establishment of biofilms, activating the host immune response leading to tissue damage. Biosurfactants are microbe‐derived tensioactive molecules with latent anti‐adhesive and anti‐microbial activity.

Study on Compound Percussive Drilling: Rock‐Breaking Mechanism of High Confining Pressure Formation in the East China Sea

Energy Science &Engineering, EarlyView.
ABSTRACT The effect of improving the depth of penetration (ROP) in deep, high‐confining pressure formation is closely related to the rock‐breaking method, which has become a bottleneck restricting the efficient development of oil and gas. Based on the current engineering practice of the Xihu block in the East China Sea Basin, experimental research on ...

Behavior of composite pre-flat slabs in resisting punching shear forces

Alexandria Engineering Journal, 2020
Due to large use of the composite pre-flat slabs “two layers slabs” especially manifested in pre-cast system slabs such as frequently used in bridge dicks, large thickness slabs casted on two layers or change usage of existing structure.

Punching shear capacity of flat slab-column junctions (a study by 3-D non-linear finite element analysis) [PDF]

, 1997
This thesis presents a study of punching shear capacity of flat slab-column junctions. A three dimensional non-linear finite element program based on 20 node isoparametric solid element was used for the investigation. The non-linear 3-D elastic isotropic

Efficiently Crowdsourcing Visual Importance with Punch-Hole Annotation [PDF]

arXiv
We introduce a novel crowdsourcing method for identifying important areas in graphical images through punch-hole labeling. Traditional methods, such as gaze trackers and mouse-based annotations, which generate continuous data, can be impractical in crowdsourcing scenarios. They require many participants, and the outcome data can be noisy.

Large-image Object Detection for Fine-grained Recognition of Punches Patterns in Medieval Panel Painting [PDF]

arXiv
The attribution of the author of an art piece is typically a laborious manual process, usually relying on subjective evaluations of expert figures. However, there are some situations in which quantitative features of the artwork can support these evaluations.

Hilbert Transform Technique for Analyzing Mode I Crack Growth in an Pre- Stressed Monoclinic Crystalline Strip Under Punch Pressure [PDF]

arXiv
The crux of the present study is to analyze the Mode I crack propagation behavior in a pre-stressed monoclinic crystalline strip of finite thickness and infinite extent. The investigation focuses on the effects of collinear Griffith cracks and dynamic punch loading induced by plane wave propagation.
