The main aim of the proposed approach presented in this paper is to improve Web information retrieval effectiveness by overcoming the problems associated with a typical keyword matching retrieval system, through the use of concepts and an intelligent fusion of confidence values. By exploiting the conceptual hierarchy of the WordNet (G. Miller, 1995) knowledge base, we show how to effectively encode the conceptual information in a document using the semantic information implied by the words that appear within it. Rather than treating a word as a string made up of a sequence of characters, we consider a word to represent a concept. © 2003 IEEE.

This paper presents a novel fuzzy logic based approach for the interpretation of texture queries. Tamura feature extraction technique is used to extract each texture feature of an image in the database. A term set on each Tamura feature is generated by a fuzzy clustering algorithm to pose a query in terms of natural language. The query can be expressed as a logic combination of natural language terms and tamura feature values. The performance of the technique was evaluated on Brodatz texture benchmark database. Experimental results show that the proposed technique is effective and the retrieved images indicate that those images are suitable for the specific queries. © 2003 IEEE.

The thermal stability and degradation of poly(vinyl alcohol) (PVA), PVA + H3PO4 (solid polymer electrolyte, SPE), PVA containing methylene blue (MB) dye and SPE (PVA + H3PO4) + MB were studied by TG/DTA/DTG and DSC techniques. The FTIR and UV-vis study of these materials indicates that MB forms a complex with the polymer by a hydrogen bonding interaction between the -OH group of the polymer and the nitrogen of MB and improves the thermal stability of the polymer. © 2002 Elsevier Science Ltd.

Thermal degradation properties of solid polymer electrolyte (poly(vinyl alcohol) + phosphoric acid)/methylene blue composites

The thermal conductivity of a filler and the thermal conductivity of a composite made from that filler influence the heat-transfer process during melt processing. The heat-transfer process from the melt to the mold wall becomes an important factor in developing the skin-core morphology. These aspects were examined in this study. The thermal conductivity of polypropylene-filler composites was estimated with a standard model for various fillers such as calcium carbonate, talc, silica, wollastonite, mica, and carbon fibers. The rate of cooling under given conditions, including the melting temperature, mold wall temperature, mass of the composite, and filler content, was estimated with standard heat-transfer equations. The time to attain the crystallization temperature for polypropylene was evaluated with a regression method with differential temperature steps. The crystallization curves were experimentally determined for the different fillers, and from them, the induction period for the onset of crystallization was estimated. These observations were correlated with the expected trends from the aforementioned formalism. The excellent fit of the curves showed that in all these cases, the thermal conductivity of the filler and composite played a dominant role in controlling the onset of the crystallization process. However, the nucleation effects became important in the later stages after the crystallization temperature was attained.

Role of heat transfer and thermal conductivity in the crystallization behavior of polypropylene-containing additives: A phenomenological model

Domestic water heater container is one of the applications that ask for high manufacturability, high strength, heat retention, corrosion resistance, hygienic operations, longer life, better ergonomics and optimum economy. Stainless steel is finding a place in this application, replacing conventional copper and enamel coated carbon steel containers. Using stainless steel for chemical handling equipment or heat transfer application is not a new concept. However using it for manufacturing container of domestic water heater is itself a state of art. With a proper understanding of behavior of stainless steel it becomes a success story. Performance of stainless steel as inner container of water heater depends on chemical composition, variation in microstructure, surface conditions, residual stresses, welding parameters, welding method and pre- and post-welding treatments. The paper discusses about the requirement of the material and suitability of the stainless steel for this particular application.

Methylene blue (MB) at small concentration is used as a photosensitizer in the solid state photoelectrochemical cells fabricated using doped and undoped polypyrrole (Ppy) coated electrodes sandwiched with solid polymer electrolyte (SPE) viz. polyvinylalcohol (PVA) doped with phosphoric acid. Different sensitization effects are observed for the same polymer-dye combination. MB sensitizes Ppy in doped state more efficiently as compared to undoped state of the polymer. The actual placement of the energy levels of dye with respect to polymer and ease with which polymer transports photogenerated charge carriers without recombination are observed to be important in such sensitization processes and governs the overall process. © 2003 Elsevier B.V.

A novel poly 3-(2-benzo thiazolyl) thiophene based conductive polymer have been synthesized and characterized using various experimental techniques. The structure and band gap (difference between Highest Occupied Molecular Orbital and Lowest Unoccupied Molecular Orbital) for the above polymer have been calculated using oligomeric approach employing B3LYP/3-21G* method and semi-empirical AM1 and ZINDO methods. The calculated band gap for monomer, dimmer and trimmer has been plotted versus 1/N (where N is the number units). The value at 1/N=0, is taken as the band gap of the polymer having long chain length. It is evident from the theoretical investigations, the band gap of poly 3-(2-benzothiazolyl) thiophene is 3.77 eV. It is possible to change the band gap by designed alteration in the thiophene framework.

The electronic transport properties of electrochemically deposited conducting polypyrrole (PPy)/Prussian Blue (PB) bilayer films have been studied by investigating the current-voltage (I-V) characteristics in dark and under white light illumination. The I-V characteristics observed are highly non-linear, both in dark and under illumination. Space charge limited conduction (SCLC) appears to be the dominant process governing the charge transport in such composite film structures which is also seen when these films are being used in photoelectrochemical or electrochromic mode. The sensitization effect appears due to relative ease of transport of the photogenerated carriers as compared the carrier transport in dark. © 2002 Elsevier Science B.V. All rights reserved.

The regio-regularity and properties of the poly [3-(2-ethylhexyl)thiophene] were studied, and compared with the poly [3′-(2-ethylhexyl)-2,2′,5′,2″-terthiophene]. The thermal stability of the polymers was improved due to the addition of thiophene rings with (2-ethylhexyl)thiophene. Due to the additional thiophenes at the 2,5 position of ethylhexylthiophene, even though the absorption wavelength was red-shifted, there is no characteristic change in photoemission for the latter polymer. Addition of thiophene rings to the 3-(2-ethylhexyl)thiophene improves the thermal properties without loosing the 3-(2-ethylhexyl)thiophene characteristics.
