    Theory of the collapsing axisymmetric cavity

    Get PDF
    We investigate the collapse of an axisymmetric cavity or bubble inside a fluid of small viscosity, like water. Any effects of the gas inside the cavity as well as of the fluid viscosity are neglected. Using a slender-body description, we show that the minimum radius of the cavity scales like h0∝tβ€²Ξ±h_0 \propto t'^{\alpha}, where tβ€²t' is the time from collapse. The exponent Ξ±\alpha very slowly approaches a universal value according to Ξ±=1/2+1/(4βˆ’ln⁑(tβ€²))\alpha=1/2 + 1/(4\sqrt{-\ln(t')}). Thus, as observed in a number of recent experiments, the scaling can easily be interpreted as evidence of a single non-trivial scaling exponent. Our predictions are confirmed by numerical simulations

    To study the dependence of the equation of state of high density nuclear matter on the term characterizing the isospin (proton-neutron) asymmetry of nuclear matter, it is necessary to measure azimuthal flow of neutrons as well as azimuthal flow of charged particles from a dense nuclear matter in the nuclear-nuclear collisions. For this purpose INR RAS is developing a new high-granular neutron detector which will be used in the BM@N experiment at the extracted beam of the Nuclotron accelerator at JINR (Dubna). This detector will identify neutrons and measure their energies in the heavy-ion collisions up to 4 GeV per nucleon. This article presents the results of measurements of the time resolution and light yields of samples of scintillation detectors with sizes 40Γ—\times40Γ—\times25 mm3^3 that will be used in a neutron detector based on the currently available fast plastic scintillator manufactured by JINR using an EQR15 11-6060D-S photodetector for light readout. For comparison, the results of measurements for a detector of the same size with a fast scintillator EJ-230 and with the same type of photodetector are given. The measurements were made on cosmic muons as well as on the electron synchrotron "Pakhra" of the Lebedev Physical Institute of the Russian Academy of Sciences located in Troitsk, Moscow

    Methodology for building extraction templates for Russian language in knowledge-based IE systems

    Get PDF
    In this paper we describe methodology for building information extraction (IE) rules. Rules are usually developed by experts and are widely used in knowledge-based IE systems. They consist of two parts: the left-hand side (LHS) of a rule is a template that matches a certain syntactico-semantic structure (SSS) and the right-hand side is an action that is executed when LHS template is matched against a particular text fragment. In the paper we describe the process of building a more complex LHS part (further in the paper we will refer to LHS as template). This methodology was used for developing the information extraction system that extracts business events from news articles written in Russian language.

    Dictionary and pattern-based recognition of organization names in Russian news texts

    Get PDF
    This paper describes a part of the event extraction system which has been developed in collaboration with HP Labs Russia. The domain of input texts is business news feeds. One of the most important event participant types is 'Organization'. This paper is focused on the problem of organization names recognition in Russian news texts. Two approaches have been implemented. The first is dictionary-based. We propose an algorithm to make a dictionary from a set of legal body full names gathered from a government registry. The main problems with the dictionary matching are incorrect stemming and significant fraction of ambiguous names among dictionary entries. The second recognition approach is based on usage of local context clues and internal name words. These words constitute patterns which are intrinsic to organization names. These patterns enable recognition of non-dictionary names. We propose an algorithm to derive such patterns from the original dictionary. Β© 2013 Hewlett-Packard Development Company, L.P

    The Nyurbinskaya and Botuobinskaya kimberlitic pipes were in the focus of a comprehensive study aimed to investigate their structural and material positions as the main deposits in the Nakyn field (Yakutian Diamondife‐ rous Province, Russia). This paper present the study results and 3D structural‐material models showing the formation of these deposits. In application to geological studies, the 3D modeling technologies allow taking into account the ani‐ sotropy of material complexes comprising kimberlite pipes, as well as inconsistencies in the structural and morpho‐ logical properties of ore‐bearing structures. In order to discover the structural positions and features of the fault‐ block structures of the deposits, tectonophysical methods were used in combination with tacheometric surveys. Based on this more comprehensive and integrated approach, the existing fault patterns were clarified in detail; elements of the internal fault structure were mapped; fault azimuths and dip angles were estimated; and thickness values were obtained. Computer processed data were used to construct 3D models showing the fault‐block structures of the Nyurbinskaya and Botuobinskaya pipes. The mineralogical, petrographic and diamond‐bearing features of various kimberlite generations comprising these pipes were investigated in order to reconstruct the morphology and spatial positions of each of the selected complexes in the current cross‐section and in accordance with intrusion phases. The 3D frame models of geological bodies were constructed for all the magmatic phases, including porphyry kimberlite and eruptive and autolithic kimberlite breccia. The structural‐material models for the Nyurbinskaya and Botuobin‐ skaya pipes were based on a synthesis of their material and structural features discovered in the previous stages of the study. The models presented in this paper are used to discuss temporal relationships between faults in the kim‐ berlitic structure and material complexes comprising the pipes. The models show that the pipes occurred in the near‐ surface structures of shear tension, which developed in the areas where the NNE‐striking fault was conjugated with the ENE‐ and NE‐striking faults in the fault zone resulting from several stage of the tectono‐magmatic activity. In this case, the kimberlite melt material was transported in discrete portions from the source through deep‐seated faults, and the faults acted as channels characterized by an increased permeability. Disjunctive elements identified in this study facilitated magma movements and localization of kimberlite bodies.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ прСдставлСны Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ комплСксного ΠΏΠΎΠ΄Ρ…ΠΎΠ΄Π° ΠΊ ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΡŽ структурной ΠΈ вСщСствСнной ΠΏΠΎΠ·ΠΈΡ†ΠΈΠΈ ΠΊΠΎΡ€Π΅Π½Π½Ρ‹Ρ… мСстороТдСний Накынского поля – ΠΊΠΈΠΌΠ±Π΅Ρ€Π»ΠΈΡ‚ΠΎΠ²Ρ‹Ρ… Ρ‚Ρ€ΡƒΠ±ΠΎΠΊ ΠΡŽΡ€Π±ΠΈΠ½ΡΠΊΠΎΠΉ ΠΈ Ботуобинской, Ρ‡Ρ‚ΠΎ нашло ΠΎΡ‚Ρ€Π°ΠΆΠ΅Π½ΠΈΠ΅ Π² Ρ‚Ρ€Π΅Ρ…ΠΌΠ΅Ρ€Π½Ρ‹Ρ… структурно‐вСщСствСнных модСлях ΠΈΡ… формирования.

    The study was focused on groundwaters sampled from boreholes drilled to deep horizons of the Udachnaya kimberlite pipe and the host sedimentary strata. Brines in the rocks significantly complicate underground mining. Analysis of the hydrogeological setting is required to ensure safety during mining to the design levels. The features of chemical composition and the geochemical evolution of brines in the crust can be clarified in a more detail on the basis of new reliable data on strong chloride saline solutions that formed in complex geological and tectonic conditions. Kimberlite and water samples were taken from the ore bodies and host sedimentary strata at the depth of 680–980 m. Conventional methods of quantitative and instrumental analysis were applied to study the chemical composition of brines. Mineral composition of kimberlite was determined by powder diffractography and X-ray fluorescence methods. Geological, structural and tectonophysical methods were used to reveal and describe the tectonic structure of the kimberlite pipe area. Groundwaters with salinity of 280–406 g/L are strong and very strong calcium chloride brines. The chlorine-bromine ratio has a small range of 48–57; the sodium-chlorine ratio varies from 0.11 to 0.18. According to their geochemical features, the studied groundwaters are metamorphosed brines that have analogues across the Siberian platform. Physical and chemical processes were simulated to investigate the degrees of saturation of strong brines relative to the minerals of water-bearing rocks. The simulation results show that the brines in the Western ore body of the Udachnaya pipe are strongly undersaturated in the deep horizons in comparison to carbonate, sulfate and chloride minerals. This suggests possible dilution of brines during their geochemical evolution. A detailed study of the tectonic structure identified structural elements that control the distribution and migration of groundwaters in the rocks. In the mining sites, brines occur mainly in the fault zones, fault junctions and intersections with the contacts of kimberlite bodies. Integration of hydrogeological and geostructural data can provide a basis for prediction and assessment of the sites with increased water inflow in the deep horizons involved in mining.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ прСдставлСны Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ изучСния ΠΏΠΎΠ΄Π·Π΅ΠΌΠ½Ρ‹Ρ… Π²ΠΎΠ΄, вскрытых скваТинами Π² Π³Π»ΡƒΠ±ΠΎΠΊΠΈΡ… Π³ΠΎΡ€ΠΈΠ·ΠΎΠ½Ρ‚Π°Ρ… ΠΊΠΈΠΌΠ±Π΅Ρ€Π»ΠΈΡ‚ΠΎΠ²ΠΎΠΉ Ρ‚Ρ€ΡƒΠ±ΠΊΠΈ Удачная ΠΈ Π²ΠΌΠ΅Ρ‰Π°ΡŽΡ‰ΠΈΡ… осадочных Ρ‚ΠΎΠ»Ρ‰Π°Ρ….
