Join Execution Using Fragmented Columnar Indices on GPU and MIC

The paper describes an approach to the parallel natural join execution on computing clusters with GPU and MIC Coprocessors. This approach is based on a decomposition of natural join relational operator using the column indices and domain-interval fragmentation. This decomposition admits parallel executing the resource-intensive relational operators without data transfers. All column index fragments are stored in main memory. To process the join of two relations, each pair of index fragments corresponding to particular domain interval is joined on a separate processor core. Described approach allows efficient parallel query processing for very large databases on modern computing cluster systems with many-core accelerators. A prototype of the DBMS coprocessor system was implemented using this technique. The results of computational experiments for GPU and Xeon Phi are presented. These results confirm the efficiency of proposed approach

Religions in Fictional Worlds: Infernal Religious Mythology in Fantasy Series

This article discusses the reasons behind the popularity of infernal heroes in the context of “religions in fictional worlds”. Are there any common guidelines for creating fantasy narratives? This refers to the “monads”, that are infernal cultural heroes, and the origins of their popularity in teenage series. Modern infernal heroes are generally not negative, foul or repulsive. On the contrary, as the result of inversion, as one of the methods of religious mythology, they became attractive role models for many admirers and movie fans, as well as readers of novels, on which these movies are based. Can we call religious fantasy modern fairytales for adults? Do infernal heroes start young people thinking about the bottom line of their life? Why are these characters so appealing to women – perhaps, they are the new gender myths? The author of this article tackles these and many other important issues through hermeneutic analysis of S. Meyer’s “Twilight” and “The Vampire Diaries” by L. J. Smith.   Keywords: myth, religion, religions of fictional worlds, religious mythology, fairy tale, faith, youth subculture, cultural hero, mythological meaning-making

The Formation of Low-Mass Double White Dwarfs through an Initial Phase of Stable Non-Conservative Mass Transfer

Although many double white dwarfs (DWDs) have been observed, the evolutionary channel by which they are formed from low-mass/long-period red-giant-main-sequence (RG-MS) binaries remains uncertain. The canonical explanations involve some variant of double common-envelope (CE) evolution, however it has been found that such a mechanism cannot produce the observed distribution. We present a model for the initial episode of mass transfer (MT) in RG-MS binaries, and demonstrate that their evolution into double white dwarfs need not arise through a double-CE process, as long as the initial primary's core mass (Md,c) does not exceed 0.46M$_{\odot}$. Instead, the first episode of dramatic mass loss may be stable, non-conservative MT. We find a lower bound on the fraction of transferred mass that must be lost from the system in order to provide for MT, and demonstrate the feasibility of this channel in producing observed low-mass (with M$_{d,c}$ < 0.46M$_{\odot}$) DWD systems.Comment: 2 pages, 1 figure, Conference Proceedings for the International Conference on Binaries, Mykonos, Greec

Critical Thinking in the Digital Age: Strategies of Human Resource Management

The research introduces a strategy of utilising critical thinking (CT) as an instrument of developing professional skills set in the digital age. The research aims to evaluate the potential of CT in human resources management (HRM). It has been established that the strategy of CT offers a way of intellectual improvement within the framework of professional communication. Therefore, a systematic fostering of CT allows for successful integration of affective and cognitive aspects of communication in the context of HRM. Conversely, this research has identified the potential of the offered strategy in change- and risk management. The &nbsp;CT strategy has proved itself to be an effective way of professional decision-making in key cognitive aspects as well as in effective ones (intellectual courage, perseverance, confident reasoning, independent thinking in tandem with overcoming egocentrism and sociocentrism). Based on the results of the empirical research within the modern digital environment, the long-term efficiency of the offered strategy has been substantiated; the researchers&nbsp; have outlined the potential ways of implementing the results of the study, as well as strategy’s growth point

Derivation of Theory of Thermoviscoelasticity by Means of Two-component Cosserat Continuum

We consider a mechanical model of a two-component medium whose first component is the classical continuum and the other component is the continuum having only rotational degrees of freedom. We show that the proposed model can be used for description of thermal and dissipative phenomena. Interpretation of the temperature, entropy and other thermodynamic quantities given in accordance with the proposed model is no more than the mechanical analogy. However, use of these mechanical counterparts allows one to obtain the well-known equations describing the thermal and diffusion processes within the framework of the model. The mathematical description of the proposed mechanical model includes as special cases not only the classical formulation of coupled problem of thermoelasticity but also the formulation of the coupled problem of thermoelasticity with the hyperbolic type heat conduction equation. In the context of the proposed mechanical model, an original interpretation of the volume (acoustic) viscosity and the shear viscosity is offered
