    M. N. Srinivas, the well known sociologist is widely recognised as architect of modern Indian sociology and social anthropology. His publications have been analysed by year, domain, authorship pattern, channels of communication used. Keywords, etc. The results indicate that the papers published by him are of a nature that qualify him to be a 'role model' for the younger generations to emulate. By the end of 1995, Srinivas had to his credit 144 papers which, included 33 broad papers in sociology and anthropology; 18 papers in social change; 28 papers in village studies; 12 papers on religion; 17 papers on caste and 36 papers of general popular interest. The periods 1958-61 and 1974-77, when Srinivas was 38-41 and 58-61 years old. were his most productive periods with highest publication activity

    Nonlinear analysis of fiber-reinforced folded shells enriched by nano-additives using a coupled FEM-IGA formulation

    No full text
    This paper focuses on the analysis of the nonlinear static behavior of fiber-reinforced folded shell panels enriched by nano additives. The employed nanocomposites are carbon nanotubes and graphene nanoplatelets. In this paper, a coupled formulation is developed which combines the isogeometric analysis (IGA) and the finite element method (FEM) along two directions on the shell surface. Using the mentioned coupled formulation, the benefits of IGA and FEM are employed in a combined formulation so that the FEM in the folding direction leads to avoid the multi-patch discretization and the IGA along the other direction reduces the required number of degrees of freedom to obtain accurate results. The present formulation is validated (i) by solving some problems available in the literature and (ii) by comparing to the numerical solutions from the commercial ABAQUS FEM code. The obtained results in the framework of an extensive parametric study demonstrate the applicability of the method

    Conceptual metaphor meets conceptual change

    No full text
    This paper argues that the metaphorical representation of concepts and the appropriation of language-based construals can be hypothesized as additional sources of conceptual change alongside those previously proposed. Analyses of construals implicit in the lay and scientific use of the noun energy from the perspective of the theory of conceptual metaphor are summarized. The experientially grounded metaphorical construals identified in both uses help conceptualize the shift from the concrete, naïve to the abstract, scientific understanding of energy. The case of the concept of energy motivates the more general hypothesis that an important part of learning a highly abstract (even mathematical) concept is the appropriation of experientially grounded metaphorical construals implicit in scientific discourse. Pedagogical implications of this proposal are discussed. © 2009 S.

    A better algorithm for random k-SAT

    No full text
    Let Φ be a uniformly distributed random k-SAT formula with n variables and m clauses. We present a polynomial time algorithm that finds a satisfying assignment of Φ with high probability for constraint densities m/n < (1 − εk)2k ln(k)/k, where εk → 0. Previously no efficient algorithm was known to find satisfying assignments with a nonvanishing probability beyond m/n = 1.817 · 2k/k [A. Frieze and S. Suen, J. Algorithms, 20 (1996), pp. 312–355]

    Modeling and Optimization of M-cresol Isopropylation for Obtaining N-thymol: Combining a Hybrid Artificial Neural Network with a Genetic Algorithm

    No full text
    The application of a hybrid framework based on the combination, artificial neural network-genetic algorithm (ANN-GA), for n-thymol synthesis modeling and optimization has been developed. The effects of molar ratio propylene/cresol (X1), catalyst mass (X2) and temperature (X3) on n-thymol selectivity Y1 and m-cresol conversion Y2 were studied. A 3-8-2 ANN model was found to be very suitable for reaction modeling. The multiobjective optimization, led to optimal operating conditions (0.55 ≤X1≤0.77; 1.773 g ≤ X2 ≤1.86 g; 289.74 °C ≤ X3 ≤291.33 °C) representing good solutions for obtaining high n-thymol selectivity and high m-cresol conversion. This optimal zone corresponded to n-thymol selectivity and m-cresol conversion ranging respectively in the interval [79.3; 79.5]% and [13.4 %; 23.7]%. These results were better than those obtained with a sequential method based on experimental design for which, optimum conditions led to n-thymol selectivity and m-cresol conversion values respectively equal to 67%and 11%. The hybrid method ANN-GA showed its ability to solve complex problems with a good fitting

    A study on the acoustical absorption behavior of coir fiber using miki model

    No full text
    Sound absorption capacity of natural coir fiber collected from coconut husk has been explored and predicted using Miki's empirical model. Experiments are conducted in impedance tube to validate the analytical outcomes for three samples having different thickness backed with and without air gap. Results show that the empirical model can estimate the absorption coefficient of coir fiber favourably well and shows higher accuracy than the Delany-Bazley model. Discrepancies between the predicted and measured absorption coefficient is very low although some inevitable irregularities is observed in the peak positions. However, presented Miki model can evaluate the overall acoustic behavior of coir fiber. This approach can be considered as a very simple and preliminary analytical solution for coir fiber acoustical characterization without considering several physical parameters of porous media. In addition, as a result, no complicated measuring procedure has to be followed to initiate the preliminary study for this material.M. Ayub, R. Zulkifli, M. H. Fouladi, N. Amin, M. J M No

    Differentially Private Sequential Learning (Extended Abstract)

    No full text
    In a differentially private sequential learning setting, agents introduce endogenous noise into their public actions to limit information leakage about their private signals. The impact of this privacy noise varies depending on whether the signals are continuous or binary. For continuous signals and a finite privacy budget ε > 0, we propose a smooth randomized response mechanism that adapts the noise level based on the distance to a decision threshold, in contrast to the standard randomized response with uniform noise. This allows agents’ actions to better reflect both their private signals and public history, achieving an accelerated convergence rate of Θ_ε(log n), surpassing the rate of Θ(√{log n}) in the non-private regime. In this case, privacy noise helps to amplify the log-likelihood ratio over time, improving information aggregation. For binary signals, differential privacy consistently degrades learning performance by reducing the probability of correct cascades compared to the non-private baseline. In this case, agents tend to use a constant randomized response strategy before the information cascade occurs. This constant privacy noise reduces the informativeness of their actions and hinders effective learning until an information cascade occurs. However, even for binary signals, the probability of correct cascades does not vary monotonically with the privacy budget ε. There are values of ε where the probability of a correct cascade increases as the privacy budget decreases because the threshold for initiating an information cascade increases by one when the privacy budget crosses below those values
