Linear Array

V. SUMMARY We have given parallel algorithms for recognizing and parsing context-free languages on a hypercube of p PE's, 1 5 p 5 n. The algorithms are both time-wise and space-wise optimal with respect to the most efficient sequential algorithm. The recognition algorithms were ...

This paper presents the analysis of a triangular array of nozzles in a multi-nozzle electrohydrodynamic(EHD) inkjet printing head. A methodology has been proposed to minimize the" end effect" by changing the traditional linear array of nozzles to triangular ...

The pyridine nucleotide disulfide reductase (PNDR) is a large and heterogeneous protein family divided into two classes (I and II), which reflect the divergent evolution of its characteristic disulfide redox active site. However, not all the PNDR members fit into these categories and this suggests the need of further studies to achieve a more comprehensive classification of this complex family. A workflow to improve the clusterization of protein families based on the array of linear conserved motifs is designed. The method is applied to the PNDR large family finding two main groups, which correspond to PNDR classes I and II. However, two other separate protein clusters, previously classified as class I in most databases, are outgrouped: the peroxide reductases (NAOX, NAPE) and the type II NADH dehydrogenases (NDH-2). In this way, two novel PNDR classes III and IV for NAOX/NAPE and NDH-2 respectively are proposed. By knowledge-driven biochemical and functional data analyses done on t...

A modified printed bow-tie antenna is designed to simultaneously cover the operations in the C and X-bands from 5.5 to 12.5 GHz. The presented antenna has an end fire radiation pattern that makes it suitable for integration in single and dual polarized phased array systems. The antenna exhibits small size and wide bandwidth of 91%. The radiation characteristics are presented

The recording and 3D modeling of large Cultural Heritage sites is currently receiving much attention. This has two main reasons. On the one hand UNESCO pays more attention to large cultural and natural sites and on the other hand we have a wide array of new technologies available which greatly support the efficient generation, administration and analysis of such models.

Background The perforator-based flap is one of the most common and frequently used options for soft tissue reconstruction on extremities to remedy small to medium-size defects. A Doppler probe has been used to identify these perforators for the designing of the flap base, axis and dimensions. The reliability of the handheld Doppler was assessed for its sensitivity and positive predictive values. Methods A prospective study on upper and lower extremities was designed, and 14 volunteers were selected for the study. A handheld Doppler with 8- and 10-MHz probes was used, and the volunteers were subsequently scanned using a color duplex with a linear-array probe of 7 and 10 MHz. A total of 94 perforators were identified on the back of the hand, wrist, and distal 24 cm of the leg. Results The 49 perforators marked on 10 legs produced 40 correct, 3 false-positive, and 6 false-negative results. The 33 distal intermetacarpal perforators marked on the back of 11 hands yielded 26 correct, 5 false-positive, and 2 false-negative results. The 12 dorsal carpal arch perforators marked gave 6 correct and 6 false-positive results. Conclusion Unidirectional flowmetry using a handheld Doppler is a practical and reliable method for identifying skin perforators. It can be used to plan and design a flap for soft tissue defect reconstruction of extremities in selected cases. The reliability of its use is size dependent, and vessels with a smaller diameter showed unacceptably high false-positive results.
