Scatter/Gather systems are increasingly becoming useful in browsing document corpora. Usability of the present-day systems are restricted to monolingual corpora, and their methods for clustering and labeling do not easily extend to the multilingual setting, especially in the absence of dictionaries/machine translation. In this paper, we study the cluster labeling problem for multilingual corpora in the absence of machine translation, but using comparable corpora. Using a variational approach, we show that multilingual topic models can effectively handle the cluster labeling problem, which in turn allows us to design a novel Scatter/Gather system ShoBha. Experimental results on three datasets, namely the Canadian Hansards corpus, the entire overlapping Wikipedia of English, Hindi and Bengali articles, and a trilingual news corpus containing 41,000 articles, confirm the utility of the proposed system. © 2012 Springer-Verlag Berlin Heidelberg.

Cluster labeling for multilingual scatter/gather using comparable corpora

In this paper, coupled response measurements are suggested for detection of a transverse surface crack in a cantilever beam. The crack has been modelled by a local compliance matrix of six degrees of freedom and simulated for detection. The eigenfrequencies are obtained using finite element method (FEM) and are compared with those of experiments. However, the small changes in eigenfrequencies are not enough for crack detection. The flexibility matrix contains non-diagonal terms, and thus indicating the coupling among the different modes of vibrations. A harmonic force of known amplitude and frequency is used to dynamically excite the beam in bending mode. But due to the presence of crack, the bending excitation induced the axial and torsional vibrations also. The measurements of direct (bending) response and coupled (axial and torsional) responses are carried out using triaxial accelerometer and rotational laser vibrometer (RLV). The experiments are carried out for different bending frequencies, crack depths and locations. The results indicate that the coupled responses are very sensitive to crack; hence these measurements are suggested for crack detection. © 2012 Inderscience Enterprises Ltd.

Performance of Composite Covers of landfills Subjected to Differential Settlements: Centrifuge Study

The transverse Ising Model (TIM) in one dimension is the simplest model which exhibits a quantum phase transition (QPT). Quantities related to quantum information theoretic measures like entanglement, quantum discord (QD) and fidelity are known to provide signatures of QPTs. The issue is less well explored when the quantum system is subjected to decoherence due to its interaction, represented by a quantum channel, with an environment. In this paper we study the dynamics of the mutual information I(ρ AB ), the classical correlations C(ρ AB ) and the quantum correlations Q(ρ AB ), as measured by the QD, in a two-qubit state the density matrix of which is the reduced density matrix obtained from the ground state of the TIM in 1d. The time evolution brought about by system-environment interactions is assumed to be Markovian in nature and the quantum channels considered are amplitude damping, bit-flip, phase-flip and bit-phase-flip. Each quantum channel is shown to be distinguished by a specific type of dynamics. In the case of the phase-flip channel, there is a finite time interval in which the quantum correlations are larger in magnitude than the classical correlations. For this channel as well as the bit-phase-flip channel, appropriate quantities associated with the dynamics of the correlations can be derived which signal the occurrence of a QPT. © 2012 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

Characterization of MgO Based Tunnel Barriers in Graphene Based Spin Valve Devices

Liquid atomization is a problem with applications in many fields. In the present study, an air-assisted impinging jet atomizer has been utilised and its spray characteristics have been studied at various conditions, using water as the liquid and nitrogen as the atomizing gas. Two configurations were studied: one having a central gas jet above two impinging liquid jets and another having a central liquid jet targeted by two inclined gas jets. Backlit imaging and particle/droplet imaging and analysis techniques were utilised to characterise the sprays. It was observed that the configuration with a central gas jet and impinging liquid jets resulted in better atomization that the other case. It was observed that both the breakup length of the sheet and the resulting droplet sizes, reduced with an increase in the gas flow rate. The diameter of the gas jet orifice was also found to play an important role in changing the spread of the spray, the droplet sizes and the radial distribution of droplet sizes. Overall, it is observed that by varying the gas-to-liquid ratio and nozzle orifices, it is possible to obtain a fine atomization of the spray using the air-assisted impinging jet configuration even at low injection pressures of below 0.4 MPa. © ICLASS 2012 - 12th Inte.

Experimental spray characterisation of air-assisted impinging jets

Computational Fluid Dynamics simulations are performed to study mixture preparation in the intake manifold of a small engine with Port Fuel Injection. Data from laser-based experiments on two injectors are used as inputs to the spray sub-model. The results reveal improved in-cylinder fuel distribution when the spray is directed onto the intake valve. The Sauter Mean Diameter of the spray is observed to have an insignificant effect during open valve injection, while the targeting is found to have a large influence. The methodology developed as part of this work can be used to further optimize injection parameters in such engines. Copyright © 2012 Inderscience Enterprises Ltd.

Modelling of mixture preparation in a small engine with port fuel injection

Addition of membrane in the form of vesicles is essential for the cytokinesis of animal and plant cells. In the animal cell cytokinesis, membrane fusion acts along with the contraction of an actomyosin ring to separate the cytoplasmic contents. In this study, the possible driving mechanisms for the membrane addition to the plasma membrane of the dividing animal cell and their consequences are presented. Taking cues from earlier studies, we propose that the membrane addition to the plasma membrane in the form of vesicles can be governed by the lateral tension present in the plasma membrane or, the concentrations of actin and myosin proteins at the cleavage furrow or, both simultaneously. The study attempts to elucidate the relationship between membrane addition and the force exerted by the contractile ring. The predictions from our study agree qualitatively with the experimental studies in which the vesicle fusion or the acto-myosin assembly were blocked during cytokinesis. However, the precise role of the two above mentioned mechanisms may depend on various parameters including but not limited to the cell type, organism and microenvironment around the dividing cell. © 2012 Elsevier Ltd.

Role of membrane addition in animal cell cytokinesis

The curvature of biological membranes is controlled by membrane-bound proteins. For example, during endocytosis, the sorting of membrane components, vesicle budding, and fission from the plasma membrane are mediated by adaptor and accessory proteins. Endophilin is a peripherally binding membrane protein that functions as an endocytic accessory protein. Endophilin's membrane tubulation capacity is well known. However, to understand the thermodynamic and mechanical aspects of endophilin function, experimental measurements need to be compared to quantitative theoretical models. We present measurements of curvature sorting and curvature generation of the endophilin A1 N-BAR domain on tubular membranes pulled from giant unilamellar vesicles. At low concentration, endophilin functions primarily as a membrane curvature sensor; at high concentrations, it also generates curvature. We determine the spontaneous curvature induced by endophilin and observe sigmoidal curvature/composition coupling isotherms that saturate at high membrane tensions and protein solution concentrations. The observation of saturation is supported by a strong dependence of lateral diffusion coefficients on protein density on the tether membrane. We develop a nonlinear curvature/composition coupling model that captures our experimental observations. Our model predicts a curvature-induced phase transition among two states with varying protein density and membrane curvature. This transition could act as a switch during endocytosis. © 2012 Biophysical Society.
