PENGGUNAAN METAFORA DALAM LAYLA MAJNUN
No full textThe study of the metaphor in a literary work can be used to find out the author’s creativity in utilizing words to concretize an abstraction through the use of metaphor. Because every human being is essentially unique, each author is assumed to have his/her own style in creating metaphors. The two questions in this article are: 1) how is the typical form of metaphor in Layla Majnun as the embodiment of creativity? ; 2) what is the function of the use of metaphor in Layla Majnun? Based on the analysis of data, a metaphor can be classified into a phrase, clause, and sentence. At the phrasal level, position or location of the image element can be either in the beginning or in the end of the topic. Meanwhile, at the level of the clause and sentence, image elements are always in the end of the topic. This latter sequence is possible because the clause part of the “explained or described” is filled syntactically by the predicate. The predicate in Indonesian is predominantly located after the subject. The study of the use of metaphor in Layla Majnun leads to the conclusion that the creativity of the author in creating metaphor reflected on how human (the author) sees the world. Because human perception is inseparable from the environment in which the author lives, develops, and interacts, the use of metaphor in Layla Majnun reflects an overview of the social life, values of culture, and customs of the Arab people at that time
QMMMW: A wrapper for QM/MM simulations with QUANTUM ESPRESSO and LAMMPS
No full textWe present QMMMW, a new program aimed at performing Quantum Mechanics/Molecular Mechanics (QM/MM) molecular dynamics. The package operates as a wrapper that patches PWscf code included in the QUANTUM ESPRESSO distribution and LAMMPS Molecular Dynamics Simulator. It is designed with a paradigm based on three guidelines: (i) minimal amount of modifications on the parent codes, (ii) flexibility and computational efficiency of the communication layer and (iii) accuracy of the Hamiltonian describing the interaction between the QM and MM subsystems. These three features are seldom present simultaneously in other implementations of QMMM. The QMMMW project is hosted by qe-forge at (http://qe-forge.org/gf/project/qmmmw/)
Karakterizacija Mg površin nizkih indeksov iz osnovnih principov
No full textIn this work, three surfaces, namely, Mg(0001), Mg(10 ̄1 0) and Mg(11 ̄2 0) are investigated by means of Density Functional Theory and Generalized Gradient Approximation first-principle calculations. The surfaces have been characterized in terms of their interlayer distances, surface energies, Projected Density of States and Surface Core Level Shifts. Contrary to what was found in previous studies based on Density Functional Theory-Local Density Approximation, the use of Generalized Gradient Approximation exchange correlation functional unravels the oscillatory behavior of both interlayer distances and Surface Core Level Shifts of Mg(10 ̄1 0). Moreover,
the Projected Density Of States of un-reconstructed Mg(11 ̄2 0) exhibit the typical quantisation of electronic levels associated to a 2D-confinement of a 3D nearly-free electron gas, as observed in nano-wires, and a Peierls instability along the unconfined direction. Different possible reconstructions on Mg(11 ̄2 0) have then been investigated. In particular, it is found that the
surface energy of (2X1) and (3X1) reconstructions is almost degenerate and lower than the surface energy of the unreconstructed Mg(11 ̄2 0) surface. Because of the quasi-degeneracy of surface energies, Mg(11 ̄2 0) surface should be composed by a combination of all the quasi degenerate phases.Delo obravnava tri kristalografske ravnine, Mg(0001), Mg(10 ̄1 0) in Mg(11 ̄2 0), iz osnovnih principov s teorijo gostotnega funkcionala (Density Functional Theory) v približku posplošenega gradienta (Generalized Gradient Approximation). Obravnavane površine so določene z medravninskimi razdaljami, površinskimi energijami, projecirano gostoto stanj (Projected Density of States) in premiki nivojev notranjih lupin. V nasprotju z rezultati raziskav, narejenih z uporabo teorijo gostotnega funkcionala v približku lokalne gostote, pa uporaba približka posplošenega gradienta izmenjalnega
korelacijskega funkcionala pokaže oscilacije medravninskih razdalj in oscilacije premikov nivojev notranjih lupin površine Mg(10 ̄1 0). Projecirana gostota stanj nerekonstruirane površine Mg(11 ̄2 0) kaže tipično kvantizacijo elektronskih nivojev, ki je značilna za 2D-omejen skoraj prosti 3D plin elektronov, kot je opaženo v nanožičkah. Vzdolž smeri brez prostorske omejenosti se pojavi tudi Peierlsova nestabilnost. Raziskane so bile različne možne rekonstrukcije površine Mg(11 ̄2 0). Ugotovljeno je bilo, da površin-
ski energiji rekonstrukcij (2X1) in (3X1) skoraj degenerirata in sta manjši od površinske energije nerekonstruirane površine Mg(11 ̄2 0). Zaradi kvazi-degeneracije površinskih energij je površina Mg(11 ̄2 0) najverjetneje sestavljena kot kombinacija vseh kvazi-degeneriranih stanj
LayLa: An open-source offline programming framework for composite deposition
No full textThe versatility of automated composite technologies granted the possibility of manufacturing laminates with a continuous variation of fiber orientation, also known as Variable Stiffness Laminates (VSL). Despite offering enough dexterity to be adapted for composite deposition, industrial manipulators are nontrivial to integrate into other applications than those originally envisioned, especially when complex curvilinear cartesian paths are desired. Further improvements in layup control and performance are necessary to induce an accurate tracking of fiber tow courses. The goals of this thesis were to a) reduce variability of layup control, b) eliminate experimental iterative steps associated with programming tow courses and c) enforce a constant laydown speed that aids consolidation quality. To achieve such objectives, a framework entitled LayLa (Laying Laminates) was developed as an offline programming tool that automatically computes the series of continuous robot motions to perform a tow course at a desired laydown speed. Experiments with LayLa were conducted for Automated Fiber Placement (AFP) using a six degrees-of-freedom KUKA manipulator, without actual deposition. From a VSL design algorithm, two fiber tow courses with a reduced turning radius were selected to be performed at a laydown speed of 0.1m/s. The overall results revealed reasonably accurate trajectory tracking of both joint and operating space variables, with errors at the end-effector position around 0.05mm and at the laydown speed of 3.2mm/s, corroborating the use of LayLa to create external commands for composite deposition.Aerospace Engineerin

Evidence of enhanced photocurrent response in corannulene films
No full textPhotoconductivity spectra measured in non-crystalline corannulene thin layers are compared to optical absorption in solution phase and thin films. The unexpected enhanced photoconductivity is correlated with GW–BSE theoretical predictions of corannulene gas-phase excitonic spectra. Theoretical analysis reveals a consistent contribution involving transitions to Super Atomic Molecular Orbitals (SAMOs), a unique set of diffuse orbitals typical of curved conjugated constructs. Results suggest SAMO population via direct photoexcitation as a potential mechanism towards exploiting these diffuse orbitals as conducting channels in suitably assembled quantum nanostructures or solids
Optical properties of silicon nanocrystallites in SiO2 matrix: Crystalline vs. amorphous case
No full textWithin a first-principles framework we show the dependence of the optical properties of silicon nanocrystallites embedded in a silica matrix on the crystalline vs. amorphous order of the system. Moreover we calculate how many-body effects modify the electronic and optical properties of the embedded silicon nanodots. A discussion about the different roles played by dimensionality, interface properties, disorder and excitonic effects on the electronic and optical properties of the confined nanostructures is presented.

Unraveling effects of disorder on the electronic structure of SiO(2) from first principles
No full textWe present a first-principles systematic study of the electronic structure of SiO(2) including the crystalline polymorphs alpha quartz and beta cristobalite, and different types of disorder leading to the amorphous phase. We start from calculations within density functional theory and proceed to more sophisticated quasiparticle calculations according to the GW scheme. Our results show that different origins of disorder have also different impact on atomic and electronic-density fluctuations, which affect the electronic structure and, in particular, the size of the mobility gap in each case.RTN EU[HPRN-CT-2002-00317]FIRB-MIUR Italy-Canada[RBIN06JB4C]FAPESPCNP
Chronicles of Majnun Layla and selected poems
No full textChronicles of Majnun Layla and Selected Poems brings together in one volume Haddad’s seminal work and a considerable selection of poems from his oeuvre, stretching over forty years. The central poem, Chronicles of Majnun Layla, recasts the seventh-century myth into a contemporary, postmodern narrative that revels in the foibles of oral transmission, weaving a small side cast of characters into the fabric of the poem. Haddad portrays Layla as a daring woman aware of her own needs and desires and not afraid to articulate them. The author succeeds in reviving this classical work of Arabian love while liberating it from its puritanical dimension and tribal overtones. The selected poems reveal Haddad’s playful yet profound meditations. A powerful lyric poet, Haddad juxtaposes classical and modern symbols, and mixes the old with the new, the sensual with the sacred, and the common with the extraordinary. Ghazoul and Verlenden’s masterful translation remains faithful to the cultural and historical context in which the original poetry was produced while also reflecting the uniqueness of the poet’s style and his poetics.https://fount.aucegypt.edu/faculty_books/1176/thumbnail.jp
