Gas hydrate (GH) is widely distributed in the world according to geological survey. Most of GH located ocean. After dissociation, strength gas bearing sediments (GHBS) decreases accompanying rise pore pressure, which can cause marine landslide. Landslide may transform into mudflows during movement on seabed. The massive submarine mudflow result serious deformation (or even damage of) pipelines,...

Crowdsourcing platforms have become quite popular due to the increasing demand of human computationbased tasks. Though the crowdsourcing systems are primarily demand-driven like MTurk, supply-driven marketplaces are becoming increasingly popular. Fiverr is a fast growing supply-driven marketplace where the sellers post micro-tasks (gigs) and users purchase them for prices as low as $5. In this ...

Abstract The link-prediction of complex networks is a new method network structure mining, which different from the traditional methods based on machine learning. It reveals those existing relations and predicts possible ones, by using similarity index structure. This paper studied topology railway link-prediction. dataset was firstly obtained sampling pre-processing. Its degree obeys power-law...

Abstract The use of chemical scale inhibitors in the oil and gas industry for subsea installations has been presented a long time, but ever-increasing exploration HPHT (high pressure high temperature) wells put demands on knowledge how rheological properties such as viscosity behave under large pressures. This work reports new experimental data high-pressure using rotational rheometer, measured...
