The low-frequency pulse wave makes the velocity of fluid in reservoir fluctuate dramatically, which results a remarkable inertia force. Darcy’s law was inapplicable to flow with strong effect inertial In this paper, non-Darcy equation and calculation method capillary number pressure displacement are established. experiments single-phase two- phase carried out. show that periodic change can decr...

The sequences generated by neuronal recurrence equations of the form xHnL ! 1A⁄j!1 h aj xHn jL qE are studied. From a neuronal recurrence equation of memory size h that describes a cycle of length rHmLä lcmIp0, p1, ... , p-1+r HmLM, a set of rHmL neuronal recurrence equations is constructed with dynamics that describe respectively the transient of length OHrHmLä lcmHp0, ... , pdLL and the cycle...

Using the concept of measure of noncompactness, we present some results concerning the existence, uniform local attractivity and global attractivity of solutions for a functional integral equation. Our results improve and extend some previous known results and based on weaker conditions. Some examples which show that our results are applicable when the previous results are inapplicable are also...

Motivated by Wallace’s thesis that pilot wave beables should be decoherence-preferred to recover quantum predictions, we consider the relation between pilot wave beables and decoherence. We prove that without any connection between beables and decoherence the overlap between macrcopic states becomes negligible. This is sufficient to recover quantum predictions, so that Wallace’s thesis has to b...

Length estimation of three dimensional digitized curves is considered. Three dimensional 26-directional chain code representation is assumed. Recent results on 3 ? D Euclidean Distance Maps are inapplicable to optimal 3 ? D length estimation. To support optimal design of three dimensional length estimators, chain code probabilities in three dimensional chain encoded digital straight lines are d...

For a graph G, the P2-path graph, P2(G), has for vertices the set of all paths of length 2 in G. Two vertices are connected when their union is a path or a cycle of length 3. We present lower bounds on the edge-connectivity, (P2(G)) of a connected graph G and give conditions for maximum connectivity. A maximally edge-connected graph is superif each minimum edge cut is trivial, and it is optimum...

We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...

To determine the amount of air pollutants, produced by Iranian automakers, and compare it with old and retrofitted vehicles have become one of the important tools of urban management. The present research uses International Vehicle Emission (IVE) modeling software in order to verify SAIPA Co. fleet emissions, based on Euro 4 emission standard (SAIPA Co. recognized as a superior Iranian brand in...

Fast muscle fibres were isolated from abdominal myotomes of Atlantic cod (Gadus morhua L.) ranging in size from 10 to 63 cm standard length (Ls). Muscle fibres were subjected to sinusoidal length changes about their resting length (Lf) and stimulated at a selected phase of the strain cycle. The work performed in each oscillatory cycle was calculated from plots offeree against muscle length, the...
