This work reviews the transient two-phase flow in porous media with engineering applications Geotechnics. It initially overviews constitutive relationships, conventional theories, and experiments. Then, corresponding limitations are discussed according to conflicting observations multiphase interfacial dynamics. Based on those findings, dynamic nonequilibrium effects were so defined, which coul...

In the present study, the author’s previous experimental investigations on the vortex induced vibration of uniform and tapered circular cylinders are numerically simulated. The circular cylinders have medium mass ratios (5.93, 6.1), low mass-damping parameters (0.0275, 0.0279) a mean diameter of 0.028m and an aspect ratio of about 14. A fully coupled two-way fluid-structure interaction (FSI) an...

Fault detection and isolation in dynamic physical systems based on analysis of transient system behavior involves monitoring for deviations and linking observed deviations to changes in system parameters. Components linked to the changed parameter values may be faulty. Functional redundancy is exploited in choosing measurements to uniquely isolate all faults. Measurement selection algorithms de...

A modeling study of dynamic threshold voltage in high K gate stack is reported in this paper. Both slow transient (STCE) and fast transient charging effect (FTCE) are included in this model. Finally, this model is applied in FinFET reliability and circuit performances are simulated. The result shows that, the drain circuit (Id) degradation in FinFET is much more obvious than normal MOSFETs with...

Nucleic acid three-way junctions (3WJs) play key roles in biological processes such as nucleic acid replication in addition to being implicated as dynamic transient intermediates in trinucleotide repeat sequences. Structural modulation of specific nucleic acid junctions could allow for control of biological processes and disease states at the nucleic acid level. Trinucleotide repeat expansions ...

A new dynamic friction force model for the longitudinal road/tire interaction for wheeled ground vehicles is validated via experiments with an actual passenger vehicle. Contrary to common static friction/slip maps, this new dynamic friction model is able to accurately capture the transient behavior of the friction force observed during transitions between braking and acceleration. A velocitydep...

We assessed the extent to which a possible synchronization between transient blood glucose declines and spontaneous meal initiation would lend support to the interpretation of a preload study with isoenergetic (1 MJ) isovolumetric high-fat or simple carbohydrate (CHO) preload drinks. Ten men (18-30 yr) fasted overnight and then were time blinded and made aware that they could request meals anyt...

BACKGROUND Fetal hydronephrosis is the most common anomaly detected on antenatal ultrasound examination, affecting 1-5% pregnancies. AIM A new management in mild antenatal renal pelvis dilatation (ARPD), using a technique based on both morphological and dynamical evaluation. MATERIALS AND METHODS Prospective study conducted during a 36-months period in 180 consecutive newborns referred as h...

detection and modification of the risk factors of stroke may be the most effective strategy for preventing its often irreversible consequences. a longitudinal prospective study was implemented to evaluate the effect of several risk factors on the course of cerebrovascular disease. the study groups were composed of 3s8 normal volunteers, and 308 patients with transient ischemic attacks. the two ...
