Effect of Wood Densification and GFRP Reinforcement on the Embedment Strength of Poplar CLT
Applied Sciences, 2023 Embedment strength is an important factor in the design and performance of connections in timber structures. This study assesses the embedment strength of lag screws in three-ply cross-laminated timber (CLT) composed of densified poplar wood with ...

Grain-scale analysis of proppant crushing and embedment using calibrated discrete element models
Acta Geotechnica, 2022 Proppant crushing and embedment in hydraulically-induced fractures is a major drawback to the recovery of unconventional oil/gas and geothermal energy production. This study provides a grain-scale analysis of the fracture evolution mechanisms of proppant

Rock Mechanics and Rock Engineering, 2021 Rock bolts are one of the main measures used to reinforce unstable blocks in a rock mass. The embedment length of fully grouted bolts in the stable and competent rock stratum behind the unstable rock blocks is an important parameter in determining ...

Optical Aspects on the Mineral Matrix – Fibre Bonding (Part 2)
Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2021 Concrete is one of the most used construction materials but there is also the need to continuously improve it. The high consumption of natural resources and energy when manufacturing cement demand a “greener” approach.

Local procrustes for manifold embedding: a measure of embedding quality and embedding algorithms [PDF]
Machine Learning, 2009 We present the Procrustes measure, a novel measure based on Procrustes rotation that enables quantitative comparison of the output of manifold-based embedding algorithms (such as LLE (Roweis and Saul, 2000) and Isomap (Tenenbaum et al, 2000)). The measure also serves as a natural tool when choosing dimension-reduction parameters.

Numerical analysis of the effect of embedment depth on the geometry of the cone failure
Journal of Physics: Conference Series, 2021 This paper presents the results of a numerical FEM analysis of the effect of embedment depth on the extent of the failure zone (cone failure) under the effect of an undercut anchor.

Review on the mechanical models and formulations of embedment of traditional timber joints in Japan
Japan Architectural Review, 2020 This paper reviews recent developments of the mechanical models and formulations for the embedment of traditional timber joints in Japan. In recent decades in Japan, seismic performance evaluation methods of traditional timber buildings have been ...

Theoretical Computer Science, 2017 In this paper we study {\em terminal embeddings}, in which one is given a finite metric $(X,d_X)$ (or a graph $G=(V,E)$) and a subset $K \subseteq X$ of its points are designated as {\em terminals}. The objective is to embed the metric into a normed space, while approximately preserving all distances among pairs that contain a terminal.

Petroleum Science, 2021 Hydraulic fracturing technology plays a key role in improving the recovery rate of shale gas. The improvement of permeability in relation to hydraulic fracturing depends on changes brought about by the proppant on the fracture structure in reservoirs ...
