Experimental Investigation of Overall Heat Transfer Coefficientin Drop wise Condensation
Abstract: The experiments are performed to study the heat transfer characteristics over a drop wise condensation. The phenomenon of drop wise condensation is in which the condensate forms into drops rather than covering the entire cooling surface with a continuous film. In drop wise condensation, heat transfer coefficient produced is 2 to 10 times greater than those produced by film wise condensation. Hence drop wise condensation is desirable as it is …

Optimization of Simulated Annealing Parameters for Bi-Criteria Multiprocessor Task Scheduling Using RSM-Grey Methodology
Abstract: AbstractSimulated Annealing (SA) has been shown as an exceptional method for finding an optimal solution to the combinatorial optimisation problems. In the present work, optimal combinations of different simulated annealing parameters have been identified by using the RSM-based grey relational analysis (GRA) for Bi-criteria multiprocessor task scheduling problem. Parameter selection is needed as SA is a meta-heuristic that does not specify all the necessary information for the optimised results. The …

A Factorial Investigation of Hyperparameter Tuning Strategies for Lasso- Based Genomic Prediction
Abstract: In an earlier comparative study of machine-learning methods for genomic prediction of wheat grain yield, we reported a counter-intuitive result: automated nested-cross-validation tuning of the Lasso regularization penalty reduced mean predictive ability relative to a fixed, arbitrarily chosen penalty (mean Pearson r falling from 0.408 to 0.349 across four environments), the opposite of the expected effect of hyperparameter tuning. We hypothesized two possible explanations at the time — high-variance penalty …
