COMPARATIVE STUDY ON TEXT DOCUMENT CLUSTERING ALGORITHMS BASED ON LATENT SEMANTIC INDEXING

ABSTRACT

In this paper, a comparative analysis of text document clustering algorithms based on latent semantic

indexing dimension reduction technique is done. In recent days, the huge amount of textual information is available in electronic form. In order to bring out the interesting patterns from very large text databases, several heuristic algorithms have been developed and still it seems to be quite challenging. Text document clustering is the fastest growing research area for grouping enormous text documents in such a way that documents within a cluster have high intra-similarity and low inter-similarity to other clusters. One of the major issues in document clustering is high dimensionality. Latent Semantic Indexing (LSI) is used with clustering algorithms to analyze the performance of text document clustering algorithms. The experimental results on the dataset constructed from Reuters21578 collections show that dimensionality reduction can improve clustering performance with respect to the computation time and average fitness of the clustered documents.

MODELING AND SIMULATION OF THE DISTILLATION

COLUMN PLATES

ABSTRACT

In this paper, we developed the modeling and simulation of different phenomena produced in the plates of a distillation column. We used bond graph tool and SYMBOLS (System Modeling Bond graph Language Simulation) software. Among the various kinds of plates, we chose the distillation column that is available in the department of technology process engineering at the University of Setif (UPO3A). The system to be modeled has a nonlinear behavior due mainly to the coupling of the different phenomena of different natures. We are indeed in presence of hydraulic, chemical and thermal energy. So the elaboration of the graphical model or the analytical one is very difficult. The working of the plates is to assure a thermodynamic balance within the column. After modeling, a SYMBOLS software validate and simulate the phenomena that occur in the plates. In the simulation results, the representation of the chemical potential, temperature, molar flow and pressure of the liquid and steam phases in the column plates justified the operating of the distillation column. Results demonstrated the feasibility of simulating multicomponent distillation under unsteady state conditions with fairly good success. Further improvements were suggested for a better accuracy.
