Deep Underground Science and EngineeringDue to their high reliability and cost‐efficiency, submarine pipelines are widely used in offshore oil and gas resource engineering. Due to the interaction of waves, currents, seabed, and pipeline structures, the soil around submarine pipelines is prone ...

Animal Conservation, EarlyView.The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...

Improving the prediction of scour around submarine pipelines [PDF]
Proceedings of the Institution of Civil Engineers - Maritime Engineering, 2016 Local scour around seabed oil, gas or water pipelines can critically affect their stability. Accurate estimation of scour around pipelines is therefore a key topic of research for marine engineers. This paper presents results from a numerical study of clear-water scour depth below a submarine pipeline for a range of steady flow conditions.

Scouring due to submerged sills
E3S Web of Conferences, 2018 As the construction of infrastructure in and around a river channel modifies the flow and sediment transport characteristics, prediction of scour depths is an integral part of engineering design.

Scour protection test for submarine pipelines under alternating tidal current
You-qi chuyun, 2022 Many oil and gas pipelines have to be laid on the seabed during the deep development of marine oil and gas resources, but the submarine pipeline suspension due to souring under marine hydrodynamic conditions is the important factor that leads to the ...

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling
Computer Graphics Forum, EarlyView.Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

3D scour below pipelines under waves and combined waves and currents
, 2014 This paper presents the results of an experimental investigation on three-dimensional local scour below a rigid pipeline subjected to wave only and combined wave and current conditions. The tests were conducted in a conventional wave flume.

Application of a Eulerian two-phase flow model to scour processes
E3S Web of Conferences, 2018 In this paper, the application of a two-phase flow model to scour processes is presented. The model is first calibrated against experimental data of unidirectional sheet-flow (one-dimensional configuration). The model is then applied to multi-dimensional

UrbanClipAtlas: A Visual Analytics Framework for Event and Scene Retrieval in Urban Videos
Computer Graphics Forum, EarlyView.Abstract Extracting actionable insights from long‐duration urban videos is often labor‐intensive: analysts must manually sift through raw footage to pinpoint target events or uncover broader behavioral trends. In this work, we present UrbanClipAtlas, a visual analytics system for exploring long urban videos recorded at street intersections ...
