We have simulated the temporal evolution of pressure due to capillary and viscous forces in two-phase drainage in porous media. We analyze our result in light of macroscopic flow equations for two-phase flow. We also investigate the effect of the trapped clusters on the pressure evolution and on the effective permeability of the system. We find that the capillary forces play an important role d...

Creating active, student-centered learning situations in postsecondary education is an ongoing challenge for engineering educators. Contemporary students familiar with visually engaging and fast-paced games can find traditional classroom methods of lecture and guided laboratory experiments limiting. This paper presents a methodology that incorporates driving simulation, motion simulation, and e...

This article describes the first public implementation and evaluation of latest version RISC-V hypervisor extension (H-extension v0.6.1) specification in a Rocket chip core. To perform meaningful for modern multi-core embedded mixedcriticality systems, we have ported Bao, an open-source static partitioning hypervisor, to RISC-V. We also extended platformlevel interrupt controller (PLIC) enable ...

Advanced false data injection attack in targeted malware intrusion is becoming an emerging severe threat to the Supervisory Control And Data Acquisition (SCADA) system. Several intrusion detection schemes have been proposed previously [21, 3]. However, designing an effective real-time detection system for a resource-constraint device is still an open problem for the research community. In this ...

The injection of engineered water to increase the oil recovery from carbonates is increasingly becoming popular due its reduced environmental impact and low cost operation. However, related variation in electric properties rock fluid with this technique still ambiguous needs thorough investigation. This study explores electrical conductivity, ion mobility, double layer thickness, change composi...

To prevent the filtration of groundwater into used underground structure in operation through its lining, it is proposed to make two waterproofing shells by method around outer surface lining an structure; upper one made soil mass compacted cementation with reduced water permeability and lower silicate cement. shell, boreholes are drilled from cement mortar alternately injected them watered gro...

driver fatigue may impose the risk of crashes and is a leading cause of death in transportation industry. this study aimed to detect driver cognitive fatigue based on changes in eeg frequency bands in non-professional drivers during a simulated driving task. in a descriptive-analytical study, 12 healthy male car drivers took part in a two hour driving session on a simulated monotonous road, whi...

An anisotropic Hydro-Mechanical-Damage coupled model was established in the framework of thermodynamics for saturated layered rocks, which contain arbitrarily-distributed cracks smaller scales and orientated bedding planes much larger scales. The proposed considers damage growth frictional sliding shear dilatancy planes, as well interaction between planes. Numerical implementation nonlinear dev...

In a companion paper [Taron J, Elsworth D, Min K-B. Numerical simulation of thermal–hydrologic– mechanical–chemical processes in deformable, fractured porous media. Int J Rock Mech Min Sci 2009; doi:10.1016/j.ijrmms.2009.01.008] we introduced a new methodology and numerical simulator for the modeling of thermal–hydrologic–mechanical–chemical processes in dual-porosity media. In this paper we ut...
