Comparison Of Modified Dual Ternary Indexing And Multi-Key Hashing Algorithms For Music Information Retrieval

In this work we have compared two indexing algorithms that have been used to index and retrieve Carnatic music songs. We have compared a modified algorithm of the Dual ternary indexing algorithm for music indexing and retrieval with the multi-key hashing indexing algorithm proposed by us. The modification in the dual ternary algorithm was essential to handle variable length query phrase and to accommodate features specific to Carnatic music. The dual ternary indexing algorithm is adapted for Carnatic music by segmenting using the segmentation technique for Carnatic music. The dual ternary algorithm is compared with the multi-key hashing algorithm designed by us for indexing and retrieval in which features like MFCC, spectral flux, melody string and spectral centroid are used as features for indexing data into a hash table. The way in which collision resolution was handled by this hash table is different than the normal hash table approaches. It was observed that multi-key hashing based retrieval had a lesser time complexity than dual-ternary based indexing The algorithms were also compared for their precision and recall in which multi-key hashing had a better recall than modified dual ternary indexing for the sample data considered.Comment: 11 pages, 5 figure

E-prints@CMFRI: Open Access Institutional Repository of Central Marine Fisheries Research Institute

The Central Marine Fisheries Research Institute (CMFRI), is a pioneering Institute in the field of marine fisheries conducts multi disciplinary researches on marine capture and culture fisheries. The Institute was established in 1947 by the Government of India under Ministry of Agriculture with headquarters at Madras. It shifted to Mandapam Camp, Tamil Nadu in 1949. In 1967, the Institute was placed under the administrative control of the Indian Council of Agricultural Research, in the Department of Agricultural Research and Education, New Delhi and, in 1971, shifted to Kochi, Kerala. The significance of Eprints@CMFRI to the Institute is that it acts as a showcase for Institute research and enhances the professional visibility of the scientists of the Institute. It demonstrates the breath and depth of research output of CMFRI. Now the scientific output of the Institute is reaching global audiences

Structure and Rheology of the Defect-gel States of Pure and Particle-dispersed Lyotropic Lamellar Phases

We present important new results from light-microscopy and rheometry on a moderately concentrated lyotropic smectic, with and without particulate additives. Shear-treatment aligns the phase rapidly, except for a striking network of oily-streak defects, which anneals out much more slowly. If spherical particles several microns in diameter are dispersed in the lamellar medium, part of the defect network persists under shear-treatment, its nodes anchored on the particles. The sample as prepared has substantial storage and loss moduli, both of which decrease steadily under shear-treatment. Adding particles enhances the moduli and retards their decay under shear. The data for the frequency-dependent storage modulus after various durations of shear-treatment can be scaled to collapse onto a single curve. The elasticity and dissipation in these samples thus arises mainly from the defect network, not directly from the smectic elasticity and hydrodynamics.Comment: 19 pages inclusive of 12 PostScript figures, uses revtex, psfrag and epsfig. Revised version, accepted for publication in Euro. Phys. J. B, with improved images of defect structure and theoretical estimates of network elasticity and scalin

Course Manual - National Workshop on Effective Management of E-Resources in Research Libraries

The National Workshop on “Effective Management of EResources in Research Libraries" is the first of its kind organised by the Library & Documentation Centre of ICAR-Central Marine Fisheries Research Institute, Kochi. Periodic trainings on newer technologies developed in the field of Library & Information Sciences help library professionals to enhance their professional competencies that will contribute largely to the output of the parent organization. Digital repositories are the need of the hour where the Institute can showcase the research findings. ICAR-CMFRI is a pioneer in developing Institute repository and the open access repository of the Institute "eprints@cmfri" now stands 1st among ICAR Institute repositories, 3rd among Indian repositories and 343rd among the world repositories. Topics of current relevance towards development and modernisation of research libraries are included in the Workshop which is expected to help the participants to understand the possibilities and ways of supporting the research activities of the parent Institution more effectively

Re-occurrence of oilfish in the landings of the south-west coast of India

On 29.08.2008, 13 specimens of the oilfish, Ruvettus pretiosus Cocco, 1833 were recorded in the trawl landings along with a heavy catch of around 200 t of Coryphaena sp. at the Cochin fisheries harbour. The biggest specimen was 360 mm in TL with a weight of 260 g. The available literature indicates that a single specimen of R. pretiosus measuring 310 mm in TL and weighing 220 g collected from the continental slope off the Quilon Bank (09004'N lat. 75031'E long.) area during November 1968 is so far the only record from the south-west coast of India, besides the two specimens from Laccadives kept in the repository of the museum of Fisheries department at Kavarathi Island. The flesh of R. pretiosus contains more oil and hence the name oilfish. The only other gempylids recorded from the Cochin area earlier were Neoepinnula orientalis and Rexea prometheoides

Salivary cortisol in the assessment of adrenocortical function in patients with pulmonary tuberculosis

Adrenocortical function was assessed on the basis of changes in salivary cortisol in patients with pulmonary tuberculosis and the findings compared with those in healthy subjects. A method of direct radioimmunoassay of salivary cortisol was standardized and the sensitivity was 0.8 nmol/l. Cortisol levels in saliva were significantly higher in the patients than in the healthy subjects (P < 0.001). The diurnal rhythm of cortisol secretion was disturbed in the patients with a significant increase in salivary cortisol beyond 1800 h. While dexamethasone caused an appreciable suppression (87%), stimulation with ACTH (tetracosactrin) resulted in a marked increase in salivary cortisol, the increase being significantly higher in the healthy subjects than in the patients (P < 0.001). Attempts to classify subjects as positive or negative responders to tetracosactrin based on increases in salivary cortisol in relation to ‘plasma cortisol changes were however not successful, as the agreement between the two methods ranged from 73 to 80 per cent with various criteria used
