Finite-element modeling of a composite bridge deck

Fiber Reinforced Polymer (FRP) materials are being widely used for structural applications, an example being bridge decks. In this study a finite-element model using the software ANSYS is developed for an 8&inches;-thick low-profile FRP bridge deck (Prodeck 8) made of E-glass fiber and Polyester resin. The bridge deck is subjected to a patch load at the center and the finite-element results obtained in the form of deflections, strains, and equivalent flexural rigidity are compared with experimental results. A good correlation is found to exist between the finite-element results and the experimental results. A failure analysis, based on maximum stress, maximum strain and Tsai-Wu theories of the Prodeck 8 is carried and first ply failure is determined. Finally, the Prodeck 8 is evaluated for critical load by performing a buckling analysis

Knowledge Transfer with Jacobian Matching

Classical distillation methods transfer representations from a "teacher" neural network to a "student" network by matching their output activations. Recent methods also match the Jacobians, or the gradient of output activations with the input. However, this involves making some ad hoc decisions, in particular, the choice of the loss function. In this paper, we first establish an equivalence between Jacobian matching and distillation with input noise, from which we derive appropriate loss functions for Jacobian matching. We then rely on this analysis to apply Jacobian matching to transfer learning by establishing equivalence of a recent transfer learning procedure to distillation. We then show experimentally on standard image datasets that Jacobian-based penalties improve distillation, robustness to noisy inputs, and transfer learning

The purpose of the study was to examine and analyze the influence of brand image, lifestyle, and servicescape on purchasing decisions of All Day Bread consumers in Medan City. This research method is descriptive quantitative. The population in this study were customers who made purchases at the All Day Bread Medan Bakery, totaling 1924 customers. Sampling using the Slovin formula, totaling 96 people. Data analysis used the classical assumption test, and the hypothesis test was multiple linear regression analysis. The results showed, a) brand image has a significant value (0.004) smaller than 0.1 and t-count (2.975) is greater than t-table (1.661); b) lifestyle has a significant value (0.005) smaller than 0.1 and t-count (2.891) is greater than t-table (1.661); c) servicescape has a significant value (0.027) smaller than 0.1 and t-count (2.240) is greater than t-table (1.661); d) brand image, lifestyle, and servicesscpae have Fcount value (37.941) greater than Ftable (2.14), and sig (0.000) less than alpha 10 percent (0.1). Conclusions, a) brand image has a positive and significant effect on purchasing decisions on All Day Bread consumers in the city of Medan; b) lifestyle has a positive and significant effect on purchasing decisions on All Day Bread consumers in Medan; c) servicescape has an effect on purchasing decisions for All Day Bread consumers in the city of Medan.
