Classification of index partitions to boost XML query performance [PDF]

open access: yes, 2010
XML query optimization continues to occupy considerable research effort due to the increasing usage of XML data. Despite many innovations over recent years, XML databases struggle to compete with more traditional database systems. Rather than using node

Efficient shell and helically coiled tube heat exchanger using carbon nanotube-water nanofluid [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2019
Diameter and shape of tube, coil pitch and curvature ratio using 0.2% MWCNT-water nanofluid and 0.2-1% SWCNTwater nanofluid, affect the inner Nu and pressure drop in a shell and helically coiled tube heat exchanger, when numerically investigated.

A New Stiffness Performance Index: Volumetric Isotropy Index [PDF]

open access: yesMachines, 2019
A new index for a precise calculation of a manipulator’s stiffness isotropy is introduced. The proposed index is compared with the conventionally used stiffness isotropy index by making use of the investigation on R-CUBE manipulator. The proposed index is shown to produce relatively more precise results from which a higher number of isotropic poses are

Maximum Likelihood Decoder for Index Coded PSK Modulation for Priority Ordered Receivers

open access: yes, 2017
Index coded PSK modulation over an AWGN broadcast channel, for a given index coding problem (ICP) is studied. For a chosen index code and an arbitrary mapping (of broadcast vectors to PSK signal points), we have derived a decision rule for the maximum ...

A Generalized Channel Coding Theory for Distributed Communication

open access: yes, 2015
This paper presents generalized channel coding theorems for a time-slotted distributed communication system where a transmitter-receiver pair is communicating in parallel with other transmitters. Assume that the channel code of each transmitter is chosen
