Optical and thermal properties of Sm3+ and Dy3+: B2O3-BaO-LiF/AlF3 glasses have been studied. These optical materials have been characterized from the measurement of their XRD, FTIR, absorption, excitation, emission spectra and DTA-TG profiles. From the recorded photoluminescence spectra of samarium (Sm3+) glasses, four emission transitions; 4G5/2 ® 6H5/2 (565 nm), 4G5/2 ® 6H7/2 (601 nm), 4G5/2 ® 6H9/2 (648 nm) and 4G5/2 ® 6H11/2 (710 nm) with lexci = 401 nm (6H5/2 ® 4F7/2) have been observed. In the case of dysprosium (Dy3+) glasses, three emission transitions; 4F9/2 ® 6H15/2 (485 nm), 4F9/2 ® 6H13/2 (578 nm) and 4F9/2 ® 6H11/2 (667 nm) with lexci = 448 nm (6H15/2 ® 4I15/2) have been observed. For the prominent emissions only, the decay curves have been recorded in order to evaluate their lifetimes. The materials nature, structural trends and thermal properties have also been analyzed through the measurement of their XRD, FTIR and TG-DTA profiles.

Piperazine is a secondary amine with the molecular formula C4N2H12. A normal coordinate analysis (NCA) has been carried out on this molecule with a systematic set of symmetry coordinates following Wilson’s F-G matrix method based on D2h point group symmetry. The frequency assignments in the FTIR and FTR spectra have been presented. A reasonable set of potential constants evaluated for this molecule has been compared with those of related molecules and are in the characteristic range. The potential energy distribution has been evaluated using the vibrational spectral data. The potential energy distribution value obtained reflects the correctness of the assignment made.

The viscosity and ultrasound velocity of narcotic analgesic drugs in aqueous mixtures of methanol, ethanol and 1- propanol have been studied.. Various acoustical parameters have been obtained which include viscous relaxation time (Γ), free volume (Vf), internal pressure (pi) and molar cohesive energy (MCE). The dependence of these properties on solvent composition is found to originate from hydrophobic hydration phenomenon.

In this paper, the design issues of a hybrid correlator are discussed. The architecture of the hybrid correlator is similar to the conventional 4-f correlator, with a difference that the first Fourier transformation, filter synthesis and their multiplication are done digitally using a digital signal-processing unit. The input to the correlator is the scene/target captured either through a CCD camera or thermal imager. Wavelet-modified maximum average correlation height filter is used for catering the need of in-plane rotation, out-of-plane rotation and scale invariant target recognition. The product function is displayed over a high-speed spatial light modulator, which when illuminated with a laser light results correlation outputs due to optical Fourier transformation. A chirp function is employed with the filters that helps to capture the desired autocorrelation peak discarding the dc and one of the undesired autocorrelation peaks. The space-bandwidth of the processor and focal length of the required lens are discussed. The requirement of zero padding of the product function is also discussed. Simulation and experimental results are presented.

Sound velocity, density and viscosity values have been measured at 303 K in the two binary systems of cyclohexane + ethanol, 1-propanol. From these data, acoustical parameters such as adiabatic compressibility, free length, free volume and internal pressure have been estimated using the standard relations. The results are interpreted in terms of molecular interaction between the components of the mixtures. Observed excess value in all the mixture indicates that the molecular symmetry existing in the system is highly disturbed by the polar alcohol molecules and dispersive type interactions are existing in the systems.

Under very high pressure, pockets of vacuum may be created around super solid 4He crystals. Crystals of 4He may flow through pockets of vacuum, one behind the other, and since the flow in vacuum will be frictionless and 4He atoms being bosons can swap positions, the flow may appear to be superfluid. Thus, the crystals will not be flowing into each other, but will flow one behind the other, and since they are identical, the flow may appear as superfluidity of solid 4He. The thermodynamic properties of the crystal, phase transition in solid 4He and supersolid 4He , zero-point energy and the size of the region in which the particle is confined under high external pressure, have been studied.

Effective thermal diffusivity of vegetables/fruits has been determined in the temperature range 0 – 45°C. The thermal diffusivity is measured by a transient technique using temperature probes (thermocouples) inserted in the sample at a distance of 2 mm. One dimensional transient temperature distributions T(r, t) generated in the sample are measured at different positions at discrete times. An ADAM data acquisition module is used to simultaneously read and store the temperature after every one second interval with a precision of 0.001°C by GeniDaq software. The cubic spline interpolation technique is used to calculate effective thermal diffusivity. The temperature dependent thermal diffusivity has been determined for Cucumis sativus (L), Luffa acutangula (L.), Lagenaria siceraria (L.), Malus domestica (L.) and Musa acuminate (L.). The effective thermal diffusivity increases continuously with temperature.

Microstructural studies of nanocrystalline thin films of V2O5-MoO3 using X-ray diffraction, optical absorption and laser micro Raman spectroscopy

Compound thin and thick films of V2O5-MoO3 system deposited on plane glass and conducting glass by electron beam and vacuum deposition have been studied by X-ray diffraction, optical absorption, high temperature in-situ X-ray diffraction and laser micro Raman spectroscopy. The films were also subjected to hydrogen insertion through plasma technique. The band gaps of these films were found to lie in the range 2.26-2.84 eV and the variation in the band gaps of these compound thin films does not follow a linear relationship with the composition. This non-linear variation of the band gap has been explained on the basis of pseudo potential approach advocated by Philips and bond order length strength (BOLS) effect in nano crystalline semiconducting thin films. The interference pattern obtained in the transmission spectra has been utilized to calculate the film thickness which agrees well with that of the value obtained by weight difference method. Laser micro Raman spectra were studied for the films. Several bands observed for these thin films have been explained on the basis of different bending, stretching and lattice phonon vibration modes occurring in the films.

The ground-state properties of two-dimensional quantum-dot helium have been studied. The shifted 1/N expansion method has been used to solve the relative part Hamiltonian of two electrons confined in a quantum in the presence of an applied uniform magnetic field. The spin singlet-triplet transition in the ground state of the QD-helium is also shown. Based on comparisons, the eigen energies obtained by the shifted method are in excellent agreement with both exact and variational methods.

Borosilicate glasses with the addition of one of the 3d-transition metals (TiàCu) (0.1 g/100g glass) have been investigated as possible materials having bioactivity by infrared reflection spectroscopy and electrical properties after the immersion in simulated body fluid (SPF) for different interval of times. The results show obvious effects of the transition metal ions on the bioactivity of the borosilicate glasses. The results are discussed taking into consideration recent achievements that govern the formation of hydroxyapatite surface layer on glass. Also, IR and electrical results are discussed in relation to the glass composition and structure, which confirm the effect of the formation of HAp layer and the possible mixed ionic and electronic mechanisms due to the addition of transition metal oxides.

In this study, filamentary discharges have been investigated at 1.5 mm dielectric-dielectric electrode gap of a coaxial dielectric barrier discharge (DBD) quartz tube filled with nitrogen gas. Different types of discharge patterns have been established in the tube using alternating field (35-45 kHz). Electrical characteristics of the discharge have been investigated, which mainly depend on gas pressure, applied frequency and voltage amplitude. The on set of the discharge current occurs earlier at higher operating voltage due to the increased value of E/n, where E is the electric field and n is the neutral gas density. The observed phenomenon occurs due to increase in rate of voltage rise time. At higher voltage, increase in net current increases the chances of electron impact. Analysis of the voltage versus charge plot (lissajous figure) supports the theory of capacitances of a double barrier discharge. The energy consumed per cycle of the DBD source measured using lissajous figure is few milli joules. Energy consumption per cycle is the key parameter for evaluating the efficiency of the device.

Received 11 July 2007; revised 24 June 2008; accepted 8 October 2008

A novel current-mode (CM) first-order all-pass (AP) inverse filter has been presented. The proposed circuit has two inputs and a single output with both the inputs providing the first-order all-pass inverse responses independently. The circuit employs bare minimum number of both active and passive components, viz. one each of CDTA, capacitor and resistor. The output current is available at high impedance thereby making the circuit very attractive from the viewpoint of cascadibility. The realizibility condition is simple. The theoretical results are verified by PSPICE simulation.
