In this paper, we report an extension of the Space-time Conservation Element-Solution Element (CE/SE) framework based viscous flow solver. The formulation of the Courant Number Insensitive Scheme (CNIS) is explained. The developed solver is validated through simulation of 2-D problems, such as, driven cavity, and external flow over a circular cylinder. Verifications are also conducted to study ...

This paper presents Iterative Fourier Technique (IFT) and Genetic Algorithm (GA) for the synthesis of low Side lobe patterns for linear array with uniform element spacing. A comparative study is done with Array Element failure is introduced at various location of linear array in distributed and concentrated form. Quantitative results are presented to show effectiveness of the algorithms for fai...

Under the condition of super-shallow coverage and small spacing, tunnel construction is easy to cause large structural deformation. The mechanical properties supporting effect with spacing are summarized. Finite element software used simulate on group by changing distance. results show that increase distance, settlement value middle has a smaller distribution law, when distance exceeds 3 m, max...

This paper shows a two-element multiple-input–multiple-output (MIMO) circularly polarized antenna. The proposed design achieves polarization diversity by using two conventional truncated corner square patches. Since the operating bandwidth of is extremely narrow, metasurface utilized for enhancement. In open literature, several MS-based MIMO antennas have been reported. However, these designs c...

A PVDF-based 8-element ultrasound transducer array (1 mm x 1 mm element size with an inter-element spacing of 1 mm) on a silicon carrier substrate is fabricated and characterized. To improve the performance of the transducer, new CMOS-compatible fabrication technologies are introduced. These include: (1) adhesive micro-contact printing on non-radiating areas, and (2) glass microspheres (7-20 mi...

The work describes the use of a synthetic transmit aperture (STA) with a single element transmitting and all elements receiving in medical ultrasound imaging. STA technique is a novel approach to today’s commercial systems, where an image is acquired sequentially one image line at a time that puts a strict limit on the frame rate and the amount of data needed for high image quality. The STA ima...

We describe a novel mechanism of site-specific recombination in the unicellular marine cyanobacterium Synechococcus sp. PCC7002. The specific recombination sites on the smallest plasmid pAQ1 were localized by studying the properties of pAQ1-derived shuttle-vectors. We found that a palindromic element, the core sequence of which is G(G/A)CGATCGCC, functions as a resolution site for site-specific...

We study the statistics of level spacing of geometric resonances in the disordered binary networks. For a definite concentration p within the interval [0.2,0.7], numerical calculations indicate that the unfolded level spacing distribution P(t) and level number variance Sigma(2)(L) have general features. It is also shown that the short-range fluctuation P(t) and long-range spectral correlation S...

Two experiments used procedures similar to those used by R. L. Greene (1989) to test the 2-process theory of the spacing effect and, in particular, the contextual-variability subtheory that applies to free-recall performance. Experiment 1 obtained a spacing effect in free recall following intentional learning but not following incidental learning, contrary to a previous result supporting the 2-...
