Improvement of the Analytical Queries Response Time in Real-Time Data Warehouse using Materialized Views Concatenation
A real-time data warehouse is a collection of recent and hierarchical data that is used for managers’ decision-making by creating online analytical queries. The volume of data collected from data sources and entered into the real-time data warehouse is constantly increasing. Moreover, as the volume of input data to the real time data warehouse increases, the interference between online loading ...
متن کاملMethods for Real - Time
Methods for Real-Time Bin-Picking Using 2D Vision Computer vision has proved to be a valuable asset in robot automated applications. One such application is known as bin-picking, in which a robot is used to automatically pick up a number of items from a container. In some cases these “bins” contain overlapping items or even unsorted heaps. In this paper two methods are presented that use only 2...

متن کاملReal Time Phasor Data Processing using Complex Number Analysis Methods
Event detection and analytic calculations in both Wide Area Measurement Systems (WAMS) and in distribution systems including Phasor Measurement Unit (PMU) based microgrid control systems often use the independent components of the phasors (e.g. frequency or Voltage) rather than the vector representation of a phasor. This paper introduces the use of the discrete time complex Fourier Transform ba...
متن کاملReal Time Data Warehouse
Real Time Data Warehouse (RTDW) is a simulation of working of human brain. Every human brain consists of approximately one billion neurons which pass data in the shape of signals to each other via synaptic connections (about thousand trillion). The brain continuously receives sensory information; refresh its data repository and responds differently in different situations. The memory capacity o...
