A taxonomic treatment of Synopeas Förster (Platygastridae, Platygastrinae) from the island of New Guinea
No full textSynopeas from New Guinea is revised, including 16 new species and four previously named species. The concepts for these species were developed in conjunction with a CO1 analysis that includes 16 New Guinean species and 3 Synopeas species from other regions. The molecular analysis determined that the New Guinea fauna does not form a clade, indicating multiple migrations. The following species are described and keyed: S. amandae Awad, sp. nov.; S. anunu Awad, sp. nov.; S. butterilli Buhl; S. codex Awad, sp. nov.; S. csoszi Buhl; S. kalubia Awad, sp. nov.; S. kiki Awad, sp. nov.; S. kira Awad, sp. nov.; S. klingunculum Awad, sp. nov.; S. luli Awad, sp. nov.; S. occultum Awad, sp. nov.; S. pattiae Awad, sp. nov.; S. psychotriae Buhl; S. pterocarpi Buhl; S. pulupulu Awad, sp. nov.; S. roncavei Awad, sp. nov.; S. sanga Awad, sp. nov.; S. toto Awad, sp. nov.; S. valavala Awad, sp. nov.; S. zhangi Awad, sp. nov. Leptacis pleuralis (Buhl), comb. nov. is transferred from Synopeas. Images of 56 holotypes of Synopeas are made publicly available online
Discussion of "state of Practice of Building Information Modeling in the Electrical Construction Industry" by Awad S. Hanna, Michael Yeutter, and Diane G. Aoun
No full textAwad S. Hanna, Michael Yeutter, and Diane G. Aoun discuss state of practice of Building Information Modeling (BIM) in the electrical construction industry. The discussers not only complement their scholarly works, but also provide a needed contextual backdrop that will enable an ameliorated understanding of electrical systems in the construction industry. They note that the authors' study did not present an operational definition of BIM, and this renders their results as superficial and lacking context. It also means that the work eschews providing directions for future research in this fertile area
Superconducting properties of zinc substitution in Tl-2223 phase
No full textThe effect of partial replacement of copper by zinc in Tl2Ba2Ca2Cu3O10-δ superconductor phase is studied. Superconducting samples of the nominal composition Tl2Ba2Ca2Cu3-xZnx O10-δ with x ranging from 0 to 0.6 are prepared under normal pressure by a one step of solid-state reaction technique. The samples are characterized by using X-ray powder diffraction, scanning electron microscope (SEM) and EDX. The X-ray data indicate that the partial replacement of Cu2+ions by Zn2+ions does not influence the tetragonal structure of the samples, and the lattice parameters a and c vary according to the difference in the ionic radii of Cu and Zn. The superconducting parameters, such as superconducting transition temperature Tc, critical current density Jc and irreversibility field Bir are calculated from electrical resistivity and AC-magnetic susceptibility measurements. © 2007 Elsevier B.V.

D-dimensional charged Anti-de-Sitter black holes in f (T) gravity
No full textAbstract We present a D-dimensional charged Anti-de-Sitter black hole solutions in f (T) gravity, where f (T) = T + βT 2 and D ≥ 4. These solutions are characterized by flat or cylindrical horizons. The interesting feature of these solutions is the existence of inseparable electric monopole and quadrupole terms in the potential which share related momenta, in contrast with most of the known charged black hole solutions in General Relativity and its extensions. Furthermore, these solutions have curvature singularities which are milder than those of the known charged black hole solutions in General Relativity and Teleparallel Gravity. This feature can be shown by calculating some invariants of curvature and torsion tensors. Furthermore, we calculate the total energy of these black holes using the energy-momentum tensor. Finally, we show that these charged black hole solutions violate the first law of thermodynamics in agreement with previous results
Multicomponent image segmentation using a genetic algorithm and artificial neural network
No full textImage segmentation is an essential process for image analysis. Several methods were developed to segment multicomponent images, and the success of these methods depends on several factors including 1) the characteristics of the acquired image and 2) the percentage of imperfections in the process of image acquisition. The majority of these methods require a priori knowledge, which is difficult to obtain. Furthermore, they assume the existence of models that can estimate its parameters and fit to the given data. However, such a parametric approach is not robust, and its performance is severely affected by the correctness of the utilized parametric model. In this letter, a new multicomponent image segmentation method is developed using a nonparametric unsupervised artificial neural network called Kohonen's self-organizing map (SOM) and hybrid genetic algorithm (HGA). SOM is used to detect the main features that are present in the image; then, HGA is used to cluster the image into homogeneous regions without any a priori knowledge. Experiments that are performed on different satellite images confirm the efficiency and robustness of the SOM-HGA method compared to the Iterative Self-Organizing DATA analysis technique (ISODATA). © 2007 IEEE.ARIA EH, 2004, P 20 ISPRS C IST TUR, P117; AWAD M, IN PRESS INT J REMOT; BACAO F, 2005, P ICCS 2005 C, P476; Baker J.

A framework to determine maximum capacity of interconnecting DGs in distribution networks
No full textInterconnecting Distributed Generation (DG) in the distribution network is considered as an important area of power system planning. When the DG placed inappropriately, the DG can have negative impact on some important and critical characteristics of system performance such as increased power losses, degraded voltage profile, and mis-coordination between protection devices. This paper introduces a framework to determine the maximum capacity limits of interconnecting DG units in radial distribution networks in order to keep protection scheme unchanged, while the voltage profile remains within acceptable range and on the same time having the minimum power losses in the network; applying this framework in the developing countries could save money and time during the integration of DGs to the network. Detailed simulations using MATLAB software are illustrated in order to investigate the results
