various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

We sought to examine the regulation of cerebral blood flow during 10 min of recovery from mild, moderate, and heavy cycling exercise by measuring middle cerebral artery blood velocity (MCA V). Transfer function analyses between changes in arterial blood pressure and MCA V were used to assess the frequency components of dynamic cerebral autoregulation (CA). After mild and moderate exercise, the ...

Compressive sensing (CS) is a new approach for the acquisition and recovery of sparse signals and images that enables sampling rates significantly below the classical Nyquist rate. Despite significant progress in the theory and methods of CS, little headway has been made in compressive video acquisition and recovery. Video CS is complicated by the ephemeral nature of dynamic events, which makes...

This study determined whether age-related mechanisms can increase fatigue of arm muscles during maximal velocity dynamic contractions, as it occurs in the lower limb. We compared elbow flexor fatigue of young (n=10, 20.8±2.7 years) and old men (n=16, 73.8±6.1 years) during and in recovery from a dynamic and an isometric postural fatiguing task. Each task was maintained until failure while suppo...

The POWER4-based p690 systems offer the highest performance of the IBM eServer pSeries line of computers. Within the general-purpose UNIX server market, they also offer the highest levels of concurrent error detection, fault isolation, recovery, and availability. High availability is achieved by minimizing component failure rates through improvements in the base technology, and through design t...

recovery is a part of disaster management cycle during which repair and reconstruction takes place, and individuals, groups, and communities retake what they have lost and ideally the risk of future incidents reduces. life recovery is a subjective and multidimensional issue influenced by various factors, whereas valid measurable indicators in evaluating the recovery after disasters are helpful....

The fault recovery of VSC-HVDC transmission system is often influenced by many factors, such as the reactive power compensation characteristics of the inverter and the dynamic performance of DC controllers. In this paper, the PSCAD/ EMTDC simulation tool is used to study the dynamic recovery performance of VSC-HVDC system for several different var compensating devices in VSC-HVDC inverter-Fixed...

2014 Work hardening of fcc metals and diamond structure crystals is considered in a cell model. Depending on stacking fault energy and temperature dynamic recovery can occur by cross slip or climb. The remaining dislocations cause a rehardening stage IV of two different origins and in two temperature ranges before the other dynamic recovery mechanism terminates work hardening. J. Phys. France 5...
