An ultracompact, multifunctional, and highly integrated 3×2 photonic switches which were designed with the use of SiGe/Si material using UHV-chemical vapor deposition and silicon-optical technology were discussed. The photonic switches combined multiwavelengths from different input channels and switched the channels to different output channels. It was observed that the insertion loss of the device was less than 2 DB and crosstalk was between -20 DB and -25 Db. The switches were found to be used in optical power splitter, optical crossconnect, optical add-drop multiplexer and wavelength division multiplexers for applications in fiber optics communication systems, photonic integrated circuits and wavelength division multiplexed networks.

As digital video databases become more and more pervasive, finding video in large databases becomes a major problem. Because of the nature of video (streamed objects), accessing the content of such databases is inherently a time-consuming operation. This paper proposes a novel neural-fuzzy based approach for retrieving a specific video clip from a video database. Fuzzy logic is used for expressing queries in terms of natural language and neural network is designed to learn the meaning of these queries. The queries are designed based on the features such as colour and texture of shots, scenes and objects in video clips. Error back propagation algorithm is proposed to learn the meaning of queries in fuzzy terms such as "very similar", "similar" and "some-what similar." The preliminary experiments were conducted on a small video database and different combinations of queries using colour and texture features along with visual video clip and achieved very promising results.

Neural-fuzzy approach for content-based retrieval of digital video

This paper presents a fuzzy-neural approach for interpretation and fusion of colour and texture features for CBIR systems. The presented approach uses fuzzy logic to interpret queries expressed in natural language such as mostly red, many green, few red for colour feature. Tamura feature is used to represent the texture of an image in the database. A term set on each Tamura feature is generated using 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. A fusion of multiple queries is incorporated into the proposed approach. The performance of the technique was evaluated on Brodatz texture benchmark database and it was noticed that there was a prominent increase in the confidence factor for the images. Fusion experiments were conducted using neuro-fuzzy, fuzzy AND and binary AND techniques. A comparative analysis showed that fuzzy-neural approach has significantly improved the performance of CBIR system. © 2004 Elsevier B.V. All rights reserved.

The crystallization behavior, structure, and morphology developed was investigated for polypropylene containing different fillers such as silica, calcium carbonate, talc, mica, graphite, etc. by using compression-molded samples prepared at several cooling rates. It was observed that the crystallinity obtained for any given composition depended on the thermal conductivity of the filler and the PP composite containing it as well as the cooling rate to which it was subjected. These composites exhibited skin-core type of morphology and the skin layer thickness was found to depend not only on the cooling rate but also on the type of filler, its thermal conductivity, etc. These various experimental findings were discussed in light of the phenomenological model described in our earlier work, which correlates thermal conductivity and degree of crystallinity for various compositions of PP containing additives. © 2004 Wiley Periodicals, Inc.

An intelligent and monolithic integration of optical power splitter (OPS) and optically switchable cross-connect (OXC) were presented. It was found that the measured crosstalk was around -17 dB and the average insertion loss about 5.25 dB. It was also found that the crosstalk and the total insertion loss, with a bias voltage of 4.7 V, were -16.5 and 5.4 dB respectively. It was observed that the measured injection current at switch-ON state was 370 mA corresponding to an injection current density of 950 A/cm 2.

The effect of small concentration of methylene blue dye on photocurrents was studied in the solid-state photoelectrochemical cells fabricated using conducting polypyrrole-coated electrodes sandwiched with solid-polymer electrolyte, namely, polyvinylpyrrolidone with phosphoric acid. A maximum photosensitivity factor (S=ll/ld, where ll is the photocurrent and ld is the dark current) of the order of 5 is observed. The current-voltage (I-V) characteristics in such cells reveal that charge transport is mainly governed by the space charge effect. Comparison of the results presented in this paper with the ones we reported earlier [23] indicates that the matrix in which dye has been incorporated plays an important role in such sensitization processes. A matrix that can efficiently transport the photogenerated charge carriers is observed to be more suitable for such dye-sensitized devices. © 2004 Kluwer Academic Publishers.

The increase in the interaction between man and machine has made display devices indispensable for visual communication. The information which is to be communicated from a machine can be often in the form of color images. Electrochromic display device (ECD) is one of the most powerful candidate for this purpose and has various merits such as multicolor, high contrast, optical memory, and no visual dependence on viewing angle. A large number of electrochromic materials are available from almost all branches of synthetic chemistry. In this review, we have tried to describe the fundamentals of such electrochromic materials and their use in EDDs. The most important examples from major classes of electrochromic materials namely transition metal oxides, Prussian blue, phthalocyanines, viologens, fullerenes, dyes and conducting polymers (including gels) are described. Examples of their use in both prototype and commercial electrochromic devices are given. © 2002 Elsevier Science B.V. All rights reserved.

The effect of small concentration of methylene blue (MB) on photocurrents was studied in solid state photoelectrochemical cells fabricated using conducting polyaniline (PANI) coated electrodes sandwiched with a solid polymer electrolyte, viz. poly(vinyl alcohol) (PVA) with phosphoric acid. These exhibit good photoresponse to visible light (maximum photosensitivity factor of the order of 10). The current-voltage (I-V) characteristics in such cells reveal that the charge transport is ohmic. Also, an electrochemical reaction (motion of Cl- from SPE + MB to PANI) is observed at 1.2-1.3 V, which gives rise to a sudden increase of current at this particular voltage. The presence of illumination enhances this electrochemical reaction. The combined effect, i.e. ohmic charge transport and an electrochemical reaction, is observed in the I-V characteristics. Along with the dye concentration, the photosensitivity is observed to be field/voltage dependent. The sensitization effects are due to lowering of the potential barrier formed at the PANI/SPE + MB interface under illumination.
