this paper describes a series of laboratory model tests on strip footings supported on unreinforced and geogrid-reinforced sand with an inside void. the footing is subjected to a combination of static and cyclic loading. the influence of various parameters including the embedment depth of the void, the number of reinforcement layers, and the amplitude of cyclic load were studied. the results sh...

Conductivity optimization is important for hydraulic fracturing due to its key roles in determining fractured well productivity. Proppant embedment is an important mechanism that could cause a remarkable reduction in fracture width and, thus, damage the fracture conductivity. In this work a new analytical model, based on contact mechanics and the Carman–Kozeny model, is developed to calculate t...

Belousov-Zhabotinsky (BZ) autonomic hydrogel composites contain active nodes of immobilized catalyst (Ru) encased within a nonactive matrix. Designing functional hierarchies of chemical and mechanical communication between these nodes enables applications ranging from encryption, sensors, and mechanochemical actuators to artificial skin. However, robust design rules and verification of computat...

This article examines the performance of Minimax Probability Machine Regression (MPMR) for prediction of settlement(s) of shallow foundation on cohesionless soil. MPMR maximizes the minimum probability that future predicted outputs of the regression model will be within some bound of the true regression function. Width of footing (B), net applied pressure (q), average Standard Penetration Test ...

あらまし ディジタルカメラを入力デバイスとして実環境中の文字を高精度に認識するために,文字画像と同 時に認識補助のための付加情報を提示する方法が検討されている.付加情報は,人間にとって自然な形で提示さ れること,及び,幾何学的変形に対してロバストに抽出できることが要求される.本論文では,これらの要求を 満たす手法として,面積比を利用した付加情報提示手法を提案する.すなわち,文字パターンを 2 色で印字する ことを前提とし,それぞれの色の領域の面積比を特定の値とするようにデザインする.具体的には,文字に影を 付加したり輪郭線を別の色とする.これらは文字パターンのデザインとして既に行われており,提案手法はその 線幅や面積を変えるにすぎない.したがって,提案手法は様々な用途に広く応用することが可能である.面積比 はアフィン変換に不変であり,アフィン変換を受けた環境においても誤りなく抽出され...

This project considers the efficacy and scalability of embedded librarianship initiatives within the City University of New York (CUNY) library system and presents findings of an original research study conducted in 2015. Through an analysis of recent LIS literature on embedment, response data from a survey of librarians, and a selection of library position descriptions, this article examines t...

Teichroeb and Forrest [Phys. Rev. Lett. 91, 016104 (2003)] image gold nanosphere embedment into a polystyrene surface and imply the existence of a liquid surface layer. We use a viscoelastic contact mechanics model of their results to give a contrary interpretation. The surface interactions between gold and polystyrene and the indentation depth determine the loads on the nanospheres. Using bulk...
