Clustering techniques

This paper introduces a new clustering technique based on granular computing. In tradional clustering algorithms, the integration of the high shaping capability of the existing datasets becomes fussy which in turn results in inferior functioning.

In this study, Fe3O4/g-C3N4 composite was fabricated via facile hydrothermal techniques. The Fe3O4/g-C3N4 product was used as catalysts for degradation of methylene blue (MB), rhodamine B (RhB) and methyl orange (MO) degradation with ultrasonic-assisted and H2O2.

One of the natural consequences of lending practices by banks and credit institutions has been the creation of deferred and doubtful loans- a phenomenon that has become a major concern for these institutions and has had a negative impact on their revenue and expenditure. From an internal perspective, operating costs, work efficiency, profitability, customer service, branch rank, employee wages and salaries, and other qualitative indicators are significantly affected.

The document will be structured as follows: In Chapter 2 outline the methodology, discussing the computational techniques used to evaluate the interaction energies and evaluating the construction of the TT and D3(BJ) correction terms. Chapter 3 attempts to establish a foundational understanding of how these methods model vdW interactions by evaluating the performance of the corrected and uncorrected HF and DFT methods in comparison with CCSD(T) energies for a selection of inert gas dimers, and simple molecule-molecule interactions.

The thesis researches and builds an entity search technique based on implicit semantic relations using clustering methods to improve search efficiency. Apply context-aware techniques, build an vertical search engine that applies context-aware in its own knowledge base domain (aviation data). Propose to measure combinatorial similarity in the contextual query suggestion problem to improve the quality of suggestion.

Cluster analysis is an unsupervised technique of grouping related objects without considering their label or class. The objects belonging to the same cluster are relatively more homogeneous in comparison with other clusters. The application of cluster analysis is in areas like gene expression analysis, galaxy formation, natural language processing and image segmentation etc.

The clinically used beta-lactamase inhibitor clavulanic acid is produced by fermentation of Streptomyces clavuligerus. The orf6 gene of the clavulanic acid biosynthetic gene cluster in S. clavuligerus encodes a protein that shows sequence homology to ornithine acetyltransferase (OAT), the fifth enzyme of the arginine biosynthetic pathway. Orf6 was overexpressed in Escherichia coli (at  15% of total soluble protein by SDS/PAGE analysis) indicating it was not toxic to the host cells. The recombinant protein was purified (to 95% purity) by a one-step technique.

Hyaluronan-binding protein 1 (HABP1), a ubiquitous multifunctional protein, interacts with hyaluronan, globular head of complement component 1q (gC1q), and clustered mannose and has been shown to be involved in cell sig-nalling.In vitro, this recombinant protein isolated from human ®broblast exists in di€erent oligomeric forms, as is evident from the results of various independent techniques in near-physiological conditions.

Focusing on multi-document personal name disambiguation, this paper develops an agglomerative clustering approach to resolving this problem. We start from an analysis of pointwise mutual information between feature and the ambiguous name, which brings about a novel weight computing method for feature in clustering. Then a trade-off measure between within-cluster compactness and among-cluster separation is proposed for stopping clustering. After that, we apply a labeling method to find representative feature for each cluster. ...

Macadamia trees (often called the tree people Mac-ca) is one of the crops of high economic value. Macadamia is the common name for nine species of the genus Macadamia, open cross Affairs (Proteaceae) in which two species have commercial value as M. integrifolia Maiden & Betche and M.tetraphylla. L. Johnson. Both species were grown in the eastern coastal regions - South and South East Queensland - Northern New Wales of Australia.

Microdeletion Syndromes The term contiguous gene syndrome refers to genetic disorders that mimic a combination of single-gene disorders. They result from the deletion of a small number of tightly clustered genes. Because some are too small to be detected cytogenetically, they are termed microdeletions. The application of molecular techniques has led to the identification of at least 18 of these microdeletion syndromes (Table 63-4). Some of the more common ones include the Wilms' tumor–aniridia complex (WAGR), Miller Dieker syndrome (MDS), and velocardiofacial (VCF) syndrome.
