An approach to adding knowledge constraints to a data-driven generative model for Carnatic rhythm sequence
Abstract: Computational models for generative music have been a recent trend in AI based technology developments. However, an entirely data-driven strategy often falls short of capturing the naturally occurring rhythmic grouping. Guedes et al. [1,2] had proposed dictionary based and stroke-grouping based approaches to generate novel sequences in the 8-beat cycle of Aditala. More recently an attempt of incorporating arithmetic partitioning, as conceived by performers, was made [3] to get rid …

Effect of the Position of Geotextile on the Performance Parameters of the Flexible Pavement
Abstract: The major deterioration of the flexible pavement is due to the combined effect of fatigue cracking caused by excessive horizontal strain at the bottom of the bituminous layer and rutting deformation caused by excessive vertical strain at the top of subgrade layer. For designing the flexible pavement, it is necessary to determine the minimum thickness of the road crust, required to withstand the expected fatigue life and rutting life. The …
