AESTHETIC SPACE IN SYNTHETIC CUBISM, INTERPRETATION ANALYSIS OF ARMEN NAZARUDDIN'S PAINTINGS
No full textThis study aims to see the aesthetic spaces in synthetic cubism by Armen Nazaruddin. When mastering the techniques, tools and materials that are mastered, the next problem that arises is the application of aesthetic values in the form of works of art. Therefore, describing an experience of having a sense and being intellectual in giving birth to his work of art. This is what the author did to conduct an object study of Armen Nazaruddin's painting, which later could be used as a reference and reference in the development of painting in Indonesia, especially in West Sumatra. This painting really considers the principles of making principles in detail and meticulously as well as the stars of the message and meaning in it. Artists experiment with how to make use of objects around them that have no value to become more appropriate in accordance with the Minang Kabau philosophy, namely, "Nature Takambang Becomes a Teacher". Keywords: Aesthetics, Painting, Synthetic Cubism, ExperimentRuang Estetika Dalam Kubisme Sintetik, Analisis Interpretasi Terhadap Lukisan Armen NazaruddinAbstrakPenelitian ini bertujuan untuk melihat ruang-ruang estetis dalam kubisme sintetik karya Armen Nazaruddin. Ketika penguasaan teknik, alat dan bahan sudah dikuasai, persoalan selanjutnya yang muncul adalah terapan nilai estetika dalam wujud karya seni. Oleh karena itu, seniman dituntut memiliki suatu kepekaan rasa dan intelektual dalam melahirkan karya seninya. Hal inilah yang mendasari penulis melakukan objek kajian terhadap karya seni lukis Armen Nazaruddin, yang nantinya bisa dijadikan acuan serta referensi dalam perkembangan seni lukis di Indonesia, khususnya di Sumatera Barat. Lukisan ini sangat mempertimbangkan prinsip-prinsip penyusunan secara detail dan teliti dan juga tersirat pesan dan makna di dalamnya. Seniman senantiasa bereksperimentasi dengan cara memanfaatkan benda-benda yang ada di sekitarnya yang tidak memiliki nilai menjadi lebih bernilai sesuai dengan falsafah minang kabau yakni “alam takambang jadi guru”.

Stochastic Model for Phonemes Uncovers an Author-Dependency of Their Usage.
No full textWe study rank-frequency relations for phonemes, the minimal units that still relate to linguistic meaning. We show that these relations can be described by the Dirichlet distribution, a direct analogue of the ideal-gas model in statistical mechanics. This description allows us to demonstrate that the rank-frequency relations for phonemes of a text do depend on its author. The author-dependency effect is not caused by the author's vocabulary (common words used in different texts), and is confirmed by several alternative means. This suggests that it can be directly related to phonemes. These features contrast to rank-frequency relations for words, which are both author and text independent and are governed by the Zipf's law

Extraction Line and Beam Dump for the Future Electron Positron Circular Collider
No full textThe conceptual design of an extraction line and beam dump for the future electron positron circular collider is presented. The proposed extraction line, consisting of abort kicker system, spoilers and beam diagnostics apparatus transports the electron and positron beams to the main beam dumps. The beam must be spread over a large surface in order not to damage the beam dump and the window, which separates the ring from the dump. The extraction line redistributes bunches at different locations on the face of beam dump. Monte Carlo simulations using FLUKA have been performed to estimate the distribution of energy deposition on the window and beam dump to find the optimal absorber and its dimensions
Scientific author names:Errors, corrections, and identity profiles
No full textAuthorship problems are deep-rooted in the field of science communication. Some of these relate to lack of specific journal instructions. For decades, experts in journal editing and publishing have been exploring the authorship criteria and contributions deserving either co-authorship or acknowledgment. The issue of inconsistencies of listing and abbreviating author names has come to the fore lately. There are reports on the difficulties of figuring out Chinese surnames and given names of South Indians in scholarly articles. However, it seems that problems with correct listing and abbreviating author names are global. This article presents an example of swapping second (father’s) name with surname in a ‘predatory’ journal, where numerous instances of incorrectly identifying and crediting authors passed unnoticed for the journal editors, and no correction has been published. Possible solutions are discussed in relation to identifying author profiles and adjusting editorial policies to the emerging problems. Correcting mistakes with author names post-publication and integrating with the Open Researcher and Contributor ID (ORCID) platform are among them.</p

Reason: Author requested closed access (OA after 2yrs) in Vireo ETD systemMoisture gradient development of concrete that incorporates saturated fine lightweight aggregates (FLWA) is not well understood. When a concrete beam or slab is exposed to external drying, water is transmitted through the surface pores and an internal drying front forms. If additional internal water can be provided, the development of the drying front can be minimized and delayed especially during early-age drying periods. With a delay, the concrete material can gain sufficient strength to resist cracking and hypothetically reduce the rate and magnitude of moisture curling.
In order to measure the impact of external drying on concrete moisture curling, a comprehensive Box-Wilson design of experiments setup was constructed to examine three critical factors: water to cementitious ratio, FLWA content, and moist curing duration. The concrete mixtures were characterize by utilizing a high-aspect ratio beam geometry. The beams were placed on a near frictionless foundation perpendicular to their direction of curling in order to eliminate the effects of creep and self-weight. Unrestrained curling deflections were measured for the experimental combinations with the results indicating that moist curing duration and FLWA content have the highest impact on the concrete curling magnitude. In fact, greater curling occurred for mixtures that were moist cured longer. Concrete mixtures with 27% FLWA by volume of fine aggregates had a 50% reduction in unrestrained curling deflection relative to concrete mixture without FLWA.
In order to observe the effects of creep and self-weight, several of the concrete mixtures from the unrestrained beam testing were tested on an elastic foundation. An analytical solution was developed to calculate the deflections and moments in the beams given a certain curling moment, which also allowed for beam-foundation separation. Experimental results indicate that very early-age drying of restrained beams, i.e. 24 hours after hydration begins, leads to lower curling magnitudes than longer moist curing e.g., 6.5 days. Both the larger surface porosity and the high creep values for early age concrete result in this curling behavior. After a 6.5 day moist curing duration, the concrete mixtures curled more and had significantly less creep with the concrete containing FLWA reducing the beam curling magnitude.
In order to directly calculate the strain profile through the concrete beam specimen and the impact of partial replacement of fine aggregates with FLWA, an existing analytical solution was combined with measured relative humidity data. An existing cement hydration model was modified to incorporate the inclusion of FLWA and the effects of the additional water contributed to the microstructure during external drying. The modifications allowed for the pore-free bulk modulus of each tested concrete mixture to be calculated. With an accurate pore-free bulk modulus, the moisture strain gradients in the tested specimens could be calculated over a 28 day drying period. The analysis revealed that concrete without moist curing benefits greatly from the inclusion of FLWA. When moist curing is applied, the benefits of FLWA decrease with respect to the moisture strain gradients.
In order to assess the influence FLWA has on the near surface cracking potential, an air-coupled acoustic emission technique was developed to quantify cracking events occurring during early age hydration couple with external drying. The new experimental method utilizes microelectromechanical sensor (MEMS) technology to passively listen for cracking events. This type of air-coupled acoustic emission test has never been successfully implemented. The MEMS-based AE system was able to record cracking events over an 8 hour period at frequencies greater than 15kHz and sound intensities greater than -53dB for mortar specimens with and without FLWA. The experimental results indicated that the FLWA-modified mixtures had more cracking events than a natural sand or blended mortar. This suggested that the surface strains of a FLWA modified mixture are higher than an unmodified mixture, which was confirmed by the theoretical strain profile calculations. However, these high strain levels for FLWA mixture are only at the near surface and do not continue further into the bulk cross section like the virgin concrete mixtures. Thus, it is hypothesized that more cracking events occur for FLWA mixtures, which are shallower depth, where 100% natural sand mixtures had less cracks which propagated deeper into the specimen.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Armen Amirkhanian, accepted the attached license on 2016-01-03 at 20:58.The student, Armen Amirkhanian, submitted this Dissertation for approval on 2016-01-03 at 21:11.This Dissertation was approved for publication on 2016-01-04 at 13:41.Limited Restriction Lifted for Item 93211 on 2018-07-08T09:15:09Z
Rückzug der Armen: der Umfang freiwilligen Engagements hängt von der materiellen Lage ab – und von Bildung
No full text"Je niedriger das Einkommen, desto seltener engagieren sich Menschen ehrenamtlich. Und je länger Bürger in Armut leben, desto weniger sind sie zu freiwilligem Engagement bereit. Materielle Verarmung als solche kann die Abkehr vom Ehrenamt aber nur in Teilen erklären. An das Einkommen geknüpfte Bildungswege spielen ebenfalls eine Rolle, ebenso wie Persönlichkeitsmerkmale. Obwohl ihr Engagement nachlässt, halten deshalb Absteiger aus der Mittelschicht eher am Ehrenamt fest als das Gros der Armen. Die Stärkung der Zivilgesellschaft durch freiwilliges Engagement ist also nur mittelbar eine Frage der materiellen Ressourcen der Bürger."[Autorenreferat]"The lower the income, the less people volunteer. The longer they live in poverty, the less inclined they are to work on a voluntary basis. Material impoverishment can only partially explain turning away from voluntary work though. Education and personality also play an important role. Even though people are volunteering less, those who have drifted from a higher to a lower social class are more likely to keep doing voluntary work than the majority of poor people. Therefore, strengthening civil society is only indirectly a question of the citizens’ material resources."[author´s abstract
