Mile Savic as an interpreter of the recent south Slavic past
No full textThe subject of this paper is the interpretation of the recent South Slavic
past given in the works of Mile Savic, a Serbian philosopher and social
theorist, who recently passed away. The wars for territorial heritage of the
former Yugoslavia, the aggression of the NATO alliance on the Federal
Republic of Yugoslavia, the project of Euro-Atlantic integration of Serbia -
are just some of the most significant thematic points of that interpretation.
By providing an exhaustive analysis of Savic?s attitudes to these and kindred
phenomena of the recent political and social history of the region, the
author concludes that, in a large mosaic of knowledge of a ?time rich in
misfortunes? (Tacitus), the piece attributed to it by this Serbian
philosopher, who left the intellectual and life stage too early, will be, by
all means, among the most significant and precious ones.</jats:p
On the choice of the demand and hydraulic modeling approach to WDN real-time simulation
No full textThis is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.This paper aims to analyze two demand modeling approaches, i.e., top-down deterministic (TDA) and bottom-up stochastic (BUA), with particular reference to their impact on the hydraulic modeling of water distribution networks (WDNs). In the applications, the hydraulic modeling is carried out through the extended period simulation (EPS) and unsteady flow modeling (UFM). Taking as benchmark the modeling conditions that are closest to the WDN's real operation (UFM + BUA), the analysis showed that the traditional use of EPS + TDA produces large pressure head and water discharge errors, which can be attenuated only when large temporal steps (up to 1 h in the case study) are used inside EPS. The use of EPS + BUA always yields better results. Indeed, EPS + BUA already gives a good approximation of the WDN's real operation when intermediate temporal steps (larger than 2 min in the case study) are used for the simulation. The trade-off between consistency of results and computational burden makes EPS + BUA the most suitable tool for real-time WDN simulation, while benefitting from data acquired through smart meters for the parameterization of demand generation models
Electrophysiological characterization of “giant” cells in stratum radiatum of the CA3 hippocampal region
No full text Whole cell patch-clamp recording and intracellular staining with biocytin allowed the morphological and electrophysiological characterization of “giant” cells, studied in stratum (st.) radiatum of the CA3 region in 17- to 21-day-old rat hippocampal slices. These neurons had extensive dendritic arborization, a triangular soma, and a bipolar vertical orientation with axons directed to the pyramidal layer or extended into the st. oriens. Giant cells had significantly higher input resistance and shorter action potentials compared with CA3 pyramidal cells. Evoked action potentials were typically followed by an afterdepolarizing potential (ADP). During depolarizing current injection, most (80%) of recorded giant cells displayed a regular firing pattern (maximum steady-state firing rate, ∼30 Hz) characterized by a modest early accommodation, whereas irregular firing was observed in the remaining 20% of giant cells. Hyperpolarizing current pulses induced a slow inward rectification of the electrotonic voltage responses, blocked by 2 mM external Cs+. N-methyl-d-aspartate (NMDA) and non-NMDA–mediated excitatory postsynaptic currents (EPSCs) measured under voltage clamp were distinguished on the basis of their voltage dependence and sensitivity to specific NMDA and non-NMDA glutamate receptor blockers. Non-NMDA EPSCs possessed a linear current-voltage relationship. EPSCs elicited by st. lucidum stimulation were reversibly reduced (mean, 23%) by the group II metabotropic glutamate receptor agonist (2S, 1′R, 2′R, 3′R)-2-(2,3-dicarboxyl-cyclopropyl)-glycine (DCG-IV, 1 μM). GABAA-mediated postsynaptic currents were subject to paired-pulse depression that was inhibited by the GABAB antagonist CGP 55845A (5 μM). We conclude that CA3 giant cells represent a particular class of hippocampal neuron located in st. radiatum that shares only some morphological and physiological properties with principal cells. </jats:p
Optimal rehabilitation planning for aged water distribution mains considering cascading failures of interdependent infrastructure systems
No full textWater distribution networks (WDNs) with other infrastructures constitute a complex and interdependent multi-utility system. Considering interdependencies between WDNs and other urban infrastructures, this work proposes WDN intervention planning using a dynamic multi-utility approach to tackle the challenges of pressure deficits and cascading failures by the decoupling of different infrastructure systems. For this purpose, the study develops reliability indices representing the hydraulic and decoupled statuses of WDNs with neighbor infrastructures; the hydraulic reliability represents the robustness of the network against the water pressure deficit, and decoupling reliability represents the extent to which WDN elements are decoupled from other assets elements. A multi-objective optimization algorithm is employed to develop rehabilitation strategies by introducing three approaches for WDN upgrade following a phased design and construction method. Evaluating intervention plans based on construction cost, reliability and cascade effects shows that, under budget limitation conditions, decoupling a WDN could significantly save the cascade cost such that 1% improvement in the decoupling reliability brings about 157.42 billion Rials cascade cost saving to asset managers. On the other hand, the decoupled network is weak against hydraulic reliability, which could make it by far less resilient network than the coupled network with around 75% hydraulic reliability difference
Anica Savic Rebac: la erotología platónica y la estética de la ‘interconexión universal’
No full textPensadora, erudita y poeta serbia, Anica Savic Rebac (1892-1953) se mueve con ligereza en medio de grandes temas y movimientos humanísticos: la Antigüedad clásica griega, la filosofía medieval, la cultura renacentista o del romanticismo exasperado, que se proyectan al pasado y al futuro de la cultura universal. La concepción del eros platónico es su referencia más continua, desde sus primeras poesías, hasta los ensayos escritos en el último periodo, en los que conecta el pensamiento griego con Dante, Shakespeare, Spinoza, Shelley, Goethe. Como autora del siglo XX, le parece fundamental el cambio de paradigma que este siglo plantea en el campo de la historia de la cultura: el hecho de que la época contemporánea plantea de manera indiscutible que en el campo de la filosofía, literatura y arte no hay que buscar divergencias, sino profundas similitudes internas entre diferentes períodos de su desarrollo. Su obra ha sido calificada de ser ‘tan buena que parece ser escrita por un hombre escrita por un hombre’1 - un comentario que no necesita gran hermenéutica para ilustrar el destino del pensamiento filosófico femenino hasta la actualidad. Sus escritos han sido reeditados y estudiados de manera intensa en las últimas décadas en su país de origen. El presente trabajo presenta su pensamiento por primera vez en el ámbito de habla hispana. A Serbian thinker, poet and scholar, Anica Savic Rebac (1892-1953) moves through the different themes and movements of the Western cultural tradition – from the Greek classical philosophy to the Medieval philosophy, from the Renaissance culture to the Romanticism, projecting the past and the future of the universal culture. Plato’s conception of Eros is a constant of her oeuvre, and can be found from her early poetry works to her late essays. In them, she connects the Greek thought with Dante, Shakespeare, Spinoza, Shelley, Goethe. As the author of the twentieth century , she insists in the importance to understand how change the paradigm change in the field of cultural history in our era: the fact that in the field of philosophy , literature and art we don’t to have to search for the differences, but for the deep internal similarities between different periods of development. Her work has been described as “being so good that it seems to be written by a man”2 – a comment that does not need much of hermeneutics to illustrate the fate of female philosophical thought until today. Her writings have been reprinted and studied intensively in the last decades in Serbia. This paper presents for the first time the thought of Anica Savic Rebas in Spanish language

While influential studies of Russian sexuality have focused on the eroticism of early twentieth century literature and art or, conversely, on the post-Soviet proliferation of obscenity, my dissertation takes the “interim” period, roughly between 1970 and 1990, as a site for the emergence of a new pornographic language in underground, dissident, and émigré literature, countering the “no sex in the USSR” discourse of official Soviet ideology. The dissertation traces the development of Russian sexual discourse in Soviet literature, broadening our understanding of late Soviet culture to include that which is usually excluded: sexually explicit language that runs the gamut from eroticism to pornography. In the 1970s and 1980s, literary pornography arose as the antipode to puritan Soviet literature and culture. A plethora of vulgarisms and obscene words invaded literature and permitted the writers to design a new poetics of pornography as an anti-Socialist Realist style. Literary pornography appeared as a peculiar kind of freedom that allowed writers to break the taboos of sex, to liberate the Russian language and culture from the fetters of Soviet ideology, and to place themselves in opposition to the restrictive methods and discourses of official Soviet culture. In the early 1990s, Russian national identity and national pride were to be rediscovered and redefined through pornography, with the porno aesthetics of the last two decades of the Soviet state serving as a model.
My project is structured as a comparative study of Russian literary pornography written both in the USSR and in the US—a case study of four authors: Edward Limonov and Mikhail Armalinsky as “pornographers in exile;” and Viktor Erofeev and Vladimir Sorokin as “pornographers at home.” By putting these four writers in dialogue, I accentuate that pornographic literature appears as an alternative truth-carrying discursive practice in which diverse cultural and semiotic meanings are produced in and understood as a game. The writers strive to make of pornography a personal project recording their private life, traumas, and struggles, which is both entertaining and terrifying. The skeleton of late-Soviet literary pornography is the play pattern of how to live and write porn simultaneously
Simplification strategies for water distribution system modelling
No full textSome simplification strategy for water distribution network simulation models are presented herein. They are achieved by using the recently developed Enhanced Global Gradient Algorithm (EGGA). EGGA allows to simulate the hydraulic system after removing interior/serial nodes, which are those adjacent to two nodes only, without forfeiting both the energy and the mass balance equations in the system model. Thus, the total number of demand nodes and pipes in the model topology results reduced. Furthermore, EGGA formulation shows clearly that its sensitivity to the uncertainties of the boundary conditions results unchanged with respect to classical GGA. Then, this paper analyses two simplification strategies based on EGGA applying them to a real large size water network. The results show significant computational efficiency gains without sacrificing accuracy of the results
Modelling of electrical energy consumption in an electric arc furnace using artificial neural networks
No full textThe objective of this research was to use state-of-the-art artificial neural network approach to estimate the extent and effect of fluctuations in the chemical composition of stainless steel at tapping of an electric arc furnace, and thus scrap and alloy weights in the charge material mix, on the specific electrical energy consumption. Such an estimation would help to further evaluate process control strategies and optimize overall operation of the electric arc furnace. The multilayer perceptron architecture 5-5-1 with hyperbolic tangent function in the hidden layer and linear function in the output layer was used as an optimal neural network model. The model was built, tested and validated based on experimental melts of the electric arc furnace at a melt shop in Italy. The proposed model was presented as an adequate one based on the coefficient of determination (R-2) which was above 0.9 as well as other error parameters calculated. The highest effect on the electrical energy consumption has carbon content. (C) 2015 Elsevier Ltd.

Methods for preserving duration-intensity correlation on synthetically generated water-demand pulses
No full textThis is the author accepted manuscript. The final version is available from ASCE via the DOI in this record.This paper proposes the application of three different methods for preserving the correlation between duration and intensity of synthetically generated water-demand pulses. The first two methods, that is, the Iman and Conover method and the Gaussian copula, respectively, are derived from known statistical approaches, although they had never been applied to the context of demand-pulse generation. The third is a novel methodology developed in this work and is a variation in the Gaussian copula approach. Poisson models fitted with the methods are applied to reproduce the measured pulses in one household, with parameters being obtained with the method of moments. Comparisons are made with another method previously proposed in the scientific literature, showing that the three methods have similar effectiveness and are applicable under more general conditions
