Experimental and Machine Learning Study of a Modified Cymbal Piezoelectric Energy Harvester

open access: yesMicromachines
Cymbal piezoelectric energy harvesters offer an effective platform for converting mechanical vibrations into electrical energy due to their ability to exploit both longitudinal (d33) and transverse (d31) piezoelectric coefficients. However, the design of

Experimental design sequential generation and overall D-efficiency criterion for electron beam grafting of corn starch

open access: yesJournal of Physics: Conference Series, 2018
An experimental investigation of the electron beam irradiation induced grafting of acrylamide onto corn starch was performed. In this way the synthesis of water-soluble copolymers having flocculation abilities is realized. The acrylamide monomer provides a polar graft side chain which turns it into a hydrophilic copolymer.

New Series of D-efficient Covariate Designs under BIBD set-up

open access: yesInternational Journal of Statistical Sciences
In the present study, an effort has been made to construct D-efficient covariate designs in BIB design (v, b, r, k and λ) set-up when either one of k and r is odd or both k and r are odd numbers and Hadamard matrix of order k i.e., Hk does not exist. For all the developed D-efficient designs, the covariates are mutually orthogonal to each other.

Plant Friendly Input Design for Parameter Estimation in an Inertial System with Respect to D-Efficiency Constraints [PDF]

open access: yesEntropy, 2014
System identification, in practice, is carried out by perturbing processes or plants under operation. That is why in many industrial applications a plant-friendly input signal would be preferred for system identification. The goal of the study is to design the optimal input signal which is then employed in the identification experiment and to examine ...

Enhancing energy-efficient building design: a multi-agent-assisted MOEA/D approach for multi-objective optimization

open access: yesEnergy Informatics
Energy-efficient building design is often challenged by multiple optimization problems due to contradictory objectives that are often hard to balance, so an effective optimization method should be thoroughly considered.
