Is Embedding Entailed in Consumer Valuation of Food Safety Characteristics? [PDF]
Consumers’ preferences for food safety characteristics are investigated with particular focus on existence of an embedding effect. Embedding exists if consumer valuation of food safety is insensitive to scope.

Reversible watermarking scheme with image-independent embedding capacity [PDF]
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,

Numerical Modeling of Proppant Transport in Complex Hydraulic Fracture Propagation
, 2017 Hydraulic fracturing is a stimulation technique used in unconventional reservoirs to generate sufficient reservoir contact for viable production. During stimulation, proppant is pumped into the system to keep fractures open when, at a later stage ...

Experimental Study of Proppant Pack Deformation [PDF]
, 2016 Unconventional reservoirs, especially shales are drilled horizontally and hydraulically fractured for economical production. Proppant is carried and placed with the use of fracturing fluid to maintain fracture conductivity once the fracture is initiated.

Improved Proppant Transport System for Slickwater Shale Fracturing
, 2010 The primary purpose of stimulating shale reservoirs is to extend drainage radius by connecting natural fractures, thus maximizing Stimulated Reservoir Volume (SRV). A conventional proppant transport system relies on the viscosity of the fracture fluid to
