Hadoop Performance Analysis Model with Deep Data Locality [PDF]
, 2019 Background: Hadoop has become the base framework on the big data system via the simple concept that moving computation is cheaper than moving data. Hadoop increases a data locality in the Hadoop Distributed File System (HDFS) to improve the performance ...

Additive Deformations of Braided Hopf Algebras
, 2011 Additive deformations of bialgebras in the sense of J. Wirth, i.e. deformations of the multiplication map fulfilling a certain compatibility condition w.r.t. the coalgebra structure, can be generalized to braided bialgebras.

E-ETL: Framework for Managing Evolving ETL Workflows [PDF]
Foundations of Computing and Decision Sciences, 2013 AbstractData warehouses integrate external data sources (EDSs), which very often change their data structures (schemas). In many cases, such changes cause an erroneous execution of an already deployed ETL workow. Structural changes of EDSs are frequent, therefore an automatic reparation of an ETL workow, after such changes, is of a high importance ...

Requirements analysis method for extracting-transformation-loading (ETL) in data warehouse systems [PDF]
, 2009 The data warehouse (DW) system design involves several tasks such as defining the DW schemas and the ETL processes specifications, and these have been extensively studied and practiced for many years.The problems in heterogeneous data integration are ...

Smart Water Meter Using Electrical Resistance Tomography
Sensors, 2019 Smart flow monitoring is critical for sewer system management. Obstructions and restrictions to flow in discharge pipes are common and costly. We propose the use of electrical resistance tomography modality for the task of smart wastewater metering. This

ETL processes specifications generation through goal-ontology approach [PDF]
, 2011 The common design-related problems for extract, transform, load (ETL) processes are far away from being resolved due to the variation and ambiguity of user requirements and the complexity of ETL operations.These were the fundamental issues of data ...

Phase-shifting by means of an electronically tunable lens: quantitative phase imaging of biological specimens with digital holographic microscopy [PDF]
, 2016 The use of an electronically tunable lens (ETL) to produce controlled phase shifts in interferometric arrangements is shown. The performance of the ETL as a phase-shifting device is experimentally validated in phase-shifting digital holographic ...

Boundedness of spectral multipliers of generalized Laplacians on compact manifolds with boundary [PDF]
, 2017 Consider a second order, strongly elliptic negative semidefinite differential operator $L$ (maybe a system) on a compact Riemannian manifold $\overline{M}$ with smooth boundary, where the domain of $L$ is defined by a coercive boundary condition ...
