Financial Data Processing in Big Data Platforms

Today’s digital society generates more and more data on a daily basis in all areas of human activities, especially in the financial sector. Such data can be collected, stored, processed, and analyzed, providing serious analytical opportunities for the end users. A lot of such systems are implemented and work using cloud technologies, which have a number of advantages, but they use a pay-per-use model and thus are not very suitable for medium and small organizations, non-profit and academic institutions. In this paper, a system, capable of fetching, storing, and processing big data is proposed and tested with financial data. It uses an open-source component-based approach and can be custom-built and implemented in national universities or centers of competence/excellence. That can present unique opportunities to researchers and developers to use and work with Big data on economic and financial problems, to investigate dependencies, use large simulation and forecast models and analyze results, using the new technologies and Big data provided by them.

Collecting and visualizing data lineage of Spark jobs

Metadata management constitutes a key prerequisite for enterprises as they engage in data analytics and governance. Today, however, the context of data is often only manually documented by subject matter experts, and lacks completeness and reliability due to the complex nature of data pipelines. Thus, collecting data lineage—describing the origin, structure, and dependencies of data—in an automated fashion increases quality of provided metadata and reduces manual effort, making it critical for the development and operation of data pipelines. In our practice report, we propose an end-to-end solution that digests lineage via (Py‑)Spark execution plans. We build upon the open-source component Spline, allowing us to reliably consume lineage metadata and identify interdependencies. We map the digested data into an expandable data model, enabling us to extract graph structures for both coarse- and fine-grained data lineage. Lastly, our solution visualizes the extracted data lineage via a modern web app, and integrates with BMW Group’s soon-to-be open-sourced Cloud Data Hub.

Periodical Press of Kurgan City, Tobolsk Province of Late XIX — Early XX Centuries

The processes of development of mass media in the county city Kurgan, a large agricultural center of the Tobolsk province, in the late 19th — early 20th centuries are analyzed. The relevance of the study is due to the fact that for the first time in Russian historiography the system of mass media of the Kurgan district, which was known all over the world for its butter-making, is described. A brief description of the life of the city is given, typological and substantive features of periodicals are investigated. The main attention in the article is paid to the broadcast of events taking place in the county and the city by journalists. The novelty ofscientific work lies in identifying the directions of the formation of periodicals in the province. It is argued that in the province, the vector of development of newspapers and magazines is directed from specialized publications to mass ones. The history of interaction between publications created by professionals for professionals and mass-oriented newspapers and leaflets is traced. It is concluded that the materials of the regional periodicals allow expanding the source component on the history of the journalistic style in the Russian literary language and on the history of the economic growth of Russian provinces and counties in the pre-revolutionary period.

Facile One-step Redox Synthesis of Bi2o2co3/bi2o3/bi Ternary Photocatalyst Without Additional Carbon Source

Construction of heterojunction and decoration of cocatalyst are two vital strategies to accelerate migration of charge carriers. However, the fabrication routs of multi-composites are usually complex and expensive. In this work, Bi2O2CO3/Bi2O3/Bi ternary composite was fabricated via a facile one-step redox reaction. Ethylene glycol was selected as the solvent during the whole reaction process. Moreover, ethylene glycol as an excellent reductant can reduce Bi3+ into metallic Bi0 and itself is oxidized to CO32-, which would react with Bi2O3 to generate Bi2O2CO3 without additional carbon source. Component proportions in ternary composites were optimized by the control of the ratios of raw materials. Under simulate solar light, Bi-based ternary composites exhibited enhanced photodegradation efficiencies for multifarious pollutants in comparison with single and binary samples. The enhanced photocatalytic activities were ascribed to accelerated migration rate of charge carriers owing to the construction of heterojunction and decoration of cocatalyst.

Sr-Nd-Pb isotopic significance of mantle source components from Central and Western Anatolia: Melting evidences from peridotite and pyroxenite source domains

<p>Extensive magmatic activities were developed in  Central and Western Anatolia,  since middle miocene to quaternary times,   the most primitive lavas are situated in eastern end of Central (Sivas) and also western (Kula) Anatolia, besides Kula basalts are  one of the most recent basaltic rocks together with  basalts  from south-central Anatolia.   Although the magmatism is generally   observed at several different  locations, the recent   basaltic rocks in both of the regions   seem to be derived from  the melting  of the peridotite and pyroxenite  source  domains and the latter one  was ignored in previous studies as source component.</p><p> The previous studies indicate that many of the basaltic rocks from Central and Western Anatolia  are related with spinel-garnet transition, but typical Tb/Yb(N) (>1.8; [1]) and Zn/Fe   (separates peridotite-derived (Zn/Fe <12; [2]) and pyroxenite-derived (Zn/Fe 13-20); [2] melts)  Co/Fe  ratios of the basaltic rocks from  several volcanic centers from Central and Western Anatolia  reveal that   melting from the single  source component  are not solely capable of  the producing  basaltic  rocks. </p><p> Sr-Nd and Pb isotopic  compositions  clearly display the distinction  of samples which are  linked to    asthenospheric source.

Chapter 5.2b Erebus Volcanic Province: petrology

Igneous rocks of the Erebus Volcanic Province have been investigated for more than a century but many aspects of petrogenesis remain problematic. Current interpretations are assessed and summarized using a comprehensive dataset of previously published and new geochemical and geochronological data. Igneous rocks, ranging in age from 25 Ma to the present day, are mainly nepheline normative. Compositional variation is largely controlled by fractionation of olivine + clinopyroxene + magnetite/ilmenite + titanite ± kaersutite ± feldspar, with relatively undifferentiated melts being generated by <10% partial melting of a mixed spinel + garnet lherzolite source. Equilibration of radiogenic Sr, Nd, Pb and Hf is consistent with a high time-integrated HIMU sensu stricto source component and this is unlikely to be related to subduction of the palaeo-Pacific Plate around 0.5 Ga. Relatively undifferentiated whole-rock chemistry can be modelled to infer complex sources comprising depleted and enriched peridotite, HIMU, eclogite-like and carbonatite-like components. Spatial (west–east) variations in Sr, Nd and Pb isotopic compositions and Ba/Rb and Nb/Ta ratios can be interpreted to indicate increasing involvement of an eclogitic crustal component eastwards. Melting in the region is related to decompression, possibly from edge-driven mantle convection or a mantle plume.

Uncorrelated blocked force determination on plate and shell structures

Inverse force determination is commonly used to determine input forces when they are not directly measurable. If transfer functions are measured with the source component attached, the inversely determined forces are, by definition, blocked forces. The primary advantage of using blocked forces is that the receiving structure may be modified and blocked forces, in theory, are unchanged. In this research, blocked forces are determined for a plastic engine cover connected to a base plate and a compressor attached to two different structures. At lower frequencies, blocked forces are determined using routine approaches where phase is included in both transfer function and operational response measurements. At high frequencies, it is demonstrated that predictions are improved if phase is ignored and blocked forces are assumed to be uncorrelated with respect to each other. It is also shown that the uncorrelated blocked forces are still valid even when changes are made to the receiving structure.

New insights for the mantle source components of the most primitive recent basaltic rocks from central and western Anatolia: Evidences for the involvement of pyroxenite and the peridotite source domains

&lt;div&gt; &lt;p&gt;Basaltic activities&amp;#160; developed&amp;#160; extensively in central and western Anatolia since middle &amp;#8211;Miocene to quaternary time, the most primitive lavas are&amp;#160; situated at&amp;#160; the eastern end of&amp;#160; central Anatolia, (southern Sivas) and the most recent ones&amp;#160; are situtated in central (basaltic cinder cones at south of Hasanda&amp;#287;) and also in western Anatolia (Kula region),&amp;#160; Among those&amp;#160; primitive recent&amp;#160; lavas, mantle sources that are responsible for the generation of basaltic rocks is&amp;#160; still a matter of a debate. &amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;/p&gt; &lt;p&gt;Previous studies suggested&amp;#160; that&amp;#160; spinel peridotite source&amp;#160;&amp;#160; is the dominant source&amp;#160; component&amp;#160; for many of the basaltic rocks which are situated in several different locations in central Anatolia, including, Erciyes and Hasanda&amp;#287; stratovolcanoes,&amp;#160; Erkilet, Develida&amp;#287;, Karap&amp;#305;nar vents and Salanda fissure eruptions while Sivas fissure basalts in the east, &amp;#160;Gediz and Kula&amp;#160; basalts in the west, were&amp;#160; derived&amp;#160; mostly&amp;#160; from&amp;#160; the&amp;#160; garnet peridotite sources, but , the &amp;#160;specific&amp;#160; incompatible element ratios&amp;#160; and the melting model based on Rare Earth Elements obviously&amp;#160; indicate that&amp;#160; these basaltic rocks could not be solely generated&amp;#160; from&amp;#160; the garnet- spinel transition zone, &amp;#160;&amp;#160;instead another mantle source component need to be involved&amp;#160; in the generation of the basaltic rocks.&lt;/p&gt; &lt;p&gt;Tb/Yb(N) and Zn/Fe&amp;#160; ratios provide significant values&amp;#160; &amp;#160;in order to constraint for the magmas&amp;#160; generated from the asthenosphere.&amp;#160; Tb/Yb(N) ratio seperates&amp;#160; garnet &amp;#8211; spinel transition [1]&amp;#160; and Zn/Fe&amp;#160; ratio&amp;#160; displays separation between the peridotite-derived (Zn/Fe &lt;12, [2,3]) and pyroxenite-derived (13-20 [2,3]) melts. &amp;#160;Zn/Fe, as well as&amp;#160; the&amp;#160; Tb/Yb(N) ratios and the melting model display&amp;#160; that single spinel&amp;#160; source&amp;#160;&amp;#160; component&amp;#160; is not solely&amp;#160;&amp;#160; responsible for&amp;#160; the generation of&amp;#160; the basaltic rocks,&amp;#160;&amp;#160; pyroxenite&amp;#160; source domain&amp;#160; should&amp;#160;&amp;#160;&amp;#160; also&amp;#160; be involved in&amp;#160; &amp;#160;during&amp;#160; the genesis of these rocks as well, besides, the &amp;#160;contributions from &amp;#160;the both of the&amp;#160; mantle source domains also explain the&amp;#160; depleted&amp;#160; magma nature that is observed&amp;#160; in some of recent basaltic rocks ( e.g, Salanda &amp;#160;and &amp;#160;Hasanda&amp;#287;&amp;#160; volcanic&amp;#160; systems) which is diffrent &amp;#160;from the dominated alkaline character, &amp;#160;generally observed&amp;#160; as&amp;#160; the &amp;#160;&amp;#160;final products&amp;#160; of central Anatolian &amp;#160;magmatism &amp;#160;&amp;#160;&lt;/p&gt; &lt;p&gt;&lt;em&gt;1.Wang et al., 2002, J.Geophys.Res.vol:107,ECV 5 1-21&lt;/em&gt;&lt;/p&gt; &lt;p&gt;&lt;em&gt;2 .Le Roux, et al.,2011,EPSL, vol:307, 395-408&lt;/em&gt;&lt;/p&gt; &lt;/div&gt;&lt;p&gt;&lt;em&gt;3.
