A new approach is presented for easily testable two-dimensional iterative *** is an improvment on GI-testability (Group Identical testability) and is referred to as GID-testability (Group Identical and Different testability). In a GID-testable twodimensional array, the primary x and y outputs are organized into groups and every group has more than one output. This is similar to the GI-testable arrays. However,GID-testability not only ensures that identical test responses can be obtained from every output in the same group when an array is fault free, but also ensures that at least one output has different test responses (from the other outputs in a group) when a cell in the array is faulty Therefore, all faults can be detected under the assumption of a single faulty cell model. It is proved that an arbitrary two-dimensional iterative array is GID-testable if seven x-states and seven y-states are added to the original flow table of the basic cell of the ***-testability simplifies the response verification of built-in-self testing in a way similar to PL- and GI-testability[6-9]. Therefore, it is suitable for BIST design.

Zero net-liquid flow (ZNLF) is a special case of upward gas-liquid two-phase flow. It is a phenomenon observed as a gas-liquid mixture flows in a conduit but the net liquid flow rate is zero. Investigation on the liquid holdup of ZNLF is conducted in a vertical ten-meter tube with diameter of 76 mm, both for Newtonian and nonNewtonian fluids. The gas phase is air. The Newtonian fluid is water and the non-Newtonian fluids are water-based guar gel solutions. The correlations developed for predicting liquid holdup on the basis of Lockhart-Martinelli parameter are not suitable to ZNLF. A constitutive correlation for the liquid holdup of vertical ZNLF was put forward by using the mass balance. It is found that the liquid holdup in ZNLF is dependent on both the gas flow rate and the flow distribution coefficient.

In this paper, the concept of k-submesh and k-submesh connectivity fault tolerance model is proposed. And the fault tolerance of 3-D mesh networks is studied under a more realistic model in which each network node has an independent failure probability. It is first observed that if the node failure probability is fixed, then the connectivity probability of 3-D mesh networks can be arbitrarily small when the network size is sufficiently large. Thus, it is practically important for multicomputer system manufacturer to determine the upper bound for node failure probability when the probability of network connectivity and the network size are given. A novel technique is developed to formally derive lower bounds on the connectivity probability for 3-D mesh networks. The study shows that 3-D mesh networks of practical size can tolerate a large number of faulty nodes thus are reliable enough for multicomputer systems. A number of advantages of 3-D mesh networks over other popular network topologies are given. Compared to 2-D mesh networks, 3-D mesh networks are much stronger in tolerating faulty nodes, while for practical network size, the fault tolerance of 3-D mesh networks is comparable with that of hypercube networks but enjoys much lower node degree.

In this paper,we propose,analyze,and test a new fully discrete,efficient,decoupled,stable,and practically second-order time-stepping algorithm for computing MHD ensemble flow averages under uncertainties in the initial conditions and *** each viscosity and magnetic diffusivity pair,the algorithm picks the largest possible parameter q 2[0,1]to avoid the instability that arises due to the presence of some explicit viscous *** each time step,the algorithm shares the same system matrix with all J realizations but has different right-hand-side vectors for all J *** saves assembling time and computer memory,allows the reuse of the same preconditioner,and can take the advantage of block linear *** the proposed algorithm,we prove stability and convergence *** illustrate the predicted convergence rates of our analysis,numerical experiments with manufactured solutions are given on a unit square ***,we test the scheme on a benchmark channel flow over a step problem and it performs well.

The vertical cable method for acquiring and processing pre-stack 3-D marine seismic data is based on the technology developed by the US Navy for antisubmarine warfare. In order to achieve the maximum utili- zation of vertical cable field data, a new separation method of the up-going and down-going wave fields of the vertical cable data processing was developed in this paper, which is different from the separation of the down-going and up-going wave fields of normal VSP data processing. In tests with synthetic modeling data and actual field data, this newly developed method performs well and is also computationally simpler without pre-assumption conditions.
