A two-dimensional model is constructed to simulate the flow regime of the
upper part of Dibdibba sandy aquifer in Safwan-Zubair area, south of Iraq. Although
the Dibdibba Formation is a multi-layer system in the surveyed area, the suggested
conceptual model which is advocated to simulate the flow regime of aquifer is fixed
for one layer, i.e., the activity of the deeper aquifer is negligible. The model is
calibrated using trial and error procedure in two stages: steady state followed by
transient state. The outcome of the calibration process demonstrated considerable
spatial variations in transmissivities and storativites of the aquifer system. A very
good similarity between the observed and simula
Let H and K be separable complex Hilbert spaces, and let B(H,K) be the space of bounded linear operators from H to K. If H=K we write B(H) for B(H,H).In this note we study separating vectors for separators on B(HK) that have representations of the form , where AB(H),BB(K) and CB(K,H).
The present paper deals with the study of petrophysical and dynamic properties of (207) plugs which were taken from rock cores of Khasib Formation at five oil wells (No.2, AM-1 AM-2, HF-3, and HU-1) located in Missan area, South of Iraq.
A comparison was made for the studied properties deduced from laboratory and from the available well logs. (35) predictive equations are established to estimate the effective porosity, permeability, in terms of the properties that are obtained from resistivity sonic, radioactivity and neutron porosity logs. These equations showed that multiple correlation coefficients (R) have ranged between weak and excellent. Statistical relations regarding the calculated and the observed values of these propertie
Yoshida and Adachi’s diploid genetic algorithm- the so-called pseudo-Meiosis genetic Algorithm (psM GA)- was focused on preserving population diversity and adapting the population quickly to problem changes. The large population diversity provided by psM GA with good adaptation to the problem changes were effective and sufficient to tackle non-stationary traveling salesman problem. They did not apply this genetic algorithm to other problem domains, like bit-coding problems. Hence, in this paper we revisit the psM GA, apply it on bit-coding problems so as to see the effect and search power of this genetic search algorithm on this problem domain.
