Measure and integral with purely ordinal scales

We develop a purely ordinal model for aggregation functionals for lattice valued functions, comprising as special cases quantiles, the Ky Fan metric and the Sugeno integral. For modeling findings of psychological experiments like the reflection effect in decision behaviour under risk or uncertainty, we introduce reflection lattices. These are complete linear lattices endowed with an order reversing bijection like the reflection at $0$ on the real interval $[-1,1]$. Mathematically we investigate the lattice of non-void intervals in a complete linear lattice, then the class of monotone interval-valued functions and

Global existence for diffusion-electromigration systems in space dimension three and higher

We prove existence of global weak solutions for the Nernst-Planck-Poisson problem which describes the evolution of concentrations of charged species $X_1, ..., X_P$ subject to Fickian diffusion and chemical reactions in the presence of an electrical field, including in particular the Boltzmann statistics case. In contrast to the existing literature, existence is proved in any dimension. Moreover, we do not need the assumption $P = 2$ nor the assumption of equal diffusivities for all $P$ components. Our approach relies on the intrinsic energy structure and on an adequate nonlinear and curiously more regular approximate problem. The delicate passing to the limit is done in adequate functional spaces which lead to only weak solutions

Thermal analysis of a plastic helical coil heat exchanger for a domestic water storage tank

In the present study, the heat transfer coefficients of helically coiled corrugated plastic tube heat exchanger inside of the solar boiler vessel were investigated experimentally. The metal coil of the conventional solar boiler for domestic usage was replaced by a plastic tube and the results were compared with the numerical simulation and the technical documentation of the initial solar boiler. All the required parameters like inlet and outlet temperatures of tubeside and stratified temperatures, flow rate of fluids, etc. were measured using appropriate instruments. The test runs were performed for different temperatures inside the tank ranging from 30-60°C and different flow rates from which the heat transfer coefficients were calculated

Fast density-matrix based partitioning of the energy over the atoms in a molecule consistent with the Hirshfeld-I partitioning of the electron density

For the Hirshfeld-I atom-in-molecule model, associated single-atom energies and interaction energies at the Hartree-Fock level are determined efficiently in one-electron Hilbert space. In contrast to most other approaches, the energy terms are fully consistent with the partitioning of the underlying one-electron density matrix. Starting from the Hirshfeld-I atom-in-molecule model for the electron density, the molecular one-electron density matrix is partitioned with a previously introduced double-atom scheme [Vanfleteren D. et al., J Chem Phys 2010, 132, 164111]. Single-atom density matrices are constructed from the atomic and bond contributions of the double-atom scheme. Since the Hartree-Fock energy can be expressed solely in terms of the one-electron density matrix, the partitioning of the latter over the atoms in the molecule leads naturally to a corresponding partitioning of the Hartree-Fock energy. When the size of the molecule or the molecular basis set does not grow too large, the method shows considerable computational advantages compared to other approaches that require cumbersome numerical integration of the molecular energy integrals weighted by atomic weight functions.Comment: 27 pages, 1 figure, pre-refereeing JCC articl

Mastering the Siege. Ideology and the Plot of the Leningrad Blockade and the Warsaw Uprising in Adamovich and Granin, and Bialoszewski

Master narratives of the relief of major cities can find their counterparts in particular individual accounts of the same events. Whereas the former tend to be 'monologic' and are characterized by an 'epic' plot, the latter may display features of 'polyphony' and plotlessness. Works by Adamovich and Granin, and by Bialoszewski, serve as illustrations

New aesthetic, new anxieties

The New Aesthetic was a design concept and netculture phenomenon launched into the world by London designer James Bridle in 2011. It continues to attract the attention of media art, and throw up associations to a variety of situated practices, including speculative design, net criticism, hacking, free and open source software development, locative media, sustainable hardware and so on. In this book we consider the New Aesthetic: as an opportunity to rethink the relations between these contexts in the emergent episteme of computationality. There is a desperate need to confront the political pressures of neoliberalism manifested in these infrastructures. Indeed, these are risky, dangerous and problematic times; a period when critique should thrive. But here we need to forge new alliances, invent and discover problems of the common that nevertheless do not eliminate the fundamental differences in this ecology of practices. In this book, perhaps provocatively, we believe a great deal could be learned from the development of the New Aesthetic not only as a mood, but as a topic and fix for collective feeling, that temporarily mobilizes networks. Is it possible to sustain and capture these atmospheres of debate and discussion beyond knee-jerk reactions and opportunistic self-promotion? These are crucial questions that the New Aesthetic invites us to consider, if only to keep a critical network culture in place
