SIMILARITY OF BI-VARIANT TIME SERIES
This paper presents one algorithm for choosing optimal solution from a bivariant time series database. The presented algorithm uses a similarity measure to compare each object in the database to a specific suitable object. The proposed method is useful when dealing with multidimensional time series data, e.g., bi-variant time series, where c...

MODELING A PURIFICATION SYSTEM FOR EFFICIENT REMOVAL OF ABRASIVE IMPURITIES
Aluminium and silicon particles in fuel known as “cat fines” are catalytic residues from the refinery process. They can cause mechanical damage to fuel pumps, injectors, piston rings and cylinder liners. They are very hard and highly abrasive, thus causing abrasive wear to main engine components. These impurities in marine fuel mu...
