COMPRESSING DATA CUBE IN PARALLEL OLAP SYSTEMS

Compressing Data Cube in Parallel OLAP Systems

This Metal Bowl paper proposes an efficient algorithm to compress the cubes in the progress of the parallel data cube generation.This low overhead compression mechanism provides block-by-block and record-by-record compression by using tuple difference coding techniques, thereby maximizing the compression ratio and minimizing the decompression penal

DGCA3QM: DESIGN OF A DUAL GENETIC ALGORITHM BASED AUTOREGRESSION MODEL FOR CORRELATIVE PREDICTION OF AIR QUALITY METRICS

Prediction of air quality metrics is a multidomain task that involves analysis of different inter-related parameters.These parameters include, type of location, NO2 levels, SO2 levels, Respirable Suspended Particulate Matter (RSPM) levels, Fine particulate matter (PM2.5) levels, etc.Researchers have proposed a wide variety of models to predict air

Transient adhesion in a non-fully detached contact

Abstract Continuous approaching and detaching displacement usually occurs in an adhesion test.Here, we found a transient adhesion force at the end of a non-fully detached contact.This force occurred when the nominal detaching displacement was less than the Pedal Accessories traditional quasi-static theory predicted zero force point.The transient ad

A constructive heuristic for time-dependent multi-depot vehicle routing problem with time-windows and heterogeneous fleet

Body Serum In this paper, we consider the time-dependent multi-depot vehicle routing problem.The objective is to minimize the total heterogeneous fleet cost assuming that the travel time between locations depends on the departure time.Also, hard time window constraints for the customers and limitation on maximum number of the vehicles in depots mus
