A comparison of HDFS compact data formats: Avro versus Parquet / HDFS glaustųjų duomenų formatų palyginimas: Avro prieš Parquet

Mokslas: Lietuvos Ateitis, 2017
In this paper, file formats like Avro and Parquet are compared with text formats to evaluate the performance of the data queries. Different data query patterns have been evaluated. Cloudera’s open-source Apache Hadoop distribution CDH 5.4 has been chosen

Efficient implementation of the parquet equations -- role of the reducible vertex function and its kernel approximation

, 2015
We present an efficient implementation of the parquet formalism which respects the asymptotic structure of the vertex functions at both single- and two-particle levels in momentum- and frequency-space. We identify the two-particle reducible vertex as the

Comparative study on the physico-mechanical characteristics for five types of wood flooring [PDF]

Constructii: Journal of Civil Engineering Research, 2014
During the period 1600-1700, the first works with parquet elements at Versailles Palace were performed, but the high cost has made that the wooden floor to be an exclusivist product for a long time.

Parquet solution for a flat Fermi surface

, 1996
We study instabilities occurring in the electron system whose Fermi surface has flat regions on its opposite sides. Such a Fermi surface resembles Fermi surfaces of some high-$T_c$ superconductors.

Parquet approach to nonlocal vertex functions and electrical conductivity of disordered electrons

, 2000
A diagrammatic technique for two-particle vertex functions is used to describe systematically the influence of spatial quantum coherence and backscattering effects on transport properties of noninteracting electrons in a random potential. In analogy with

Field Theory and Colonialism: Indirect Colonial Situation as a Social Field in Egypt (1882–1922)

Sociology Lens, EarlyView.
ABSTRACT This paper argues that Egypt under British rule (1882–1922) constituted a field of power in which the local state of Egypt and the British administration competed to dominate three key subfields to ensure control over a contested territory: the modern courts system, policing, and agricultural production.
