To accurately, efficiently and reliably extract the parameters of single, double and triple diode solar cell models, this paper proposes a randomly initialized opposite normalized trust-region reflective (ONTRR) algorithm. The novelty of ONTRR lies primarily in two amendments to the stan...

After testing the measurement model of the lower-order construct, the latent variable scores obtained from the PLS algorithm for all three dimensions of source credibility are transferred to the main dataset in order to investigate the higher-order construct in the proposed model using the repeated ...
In PLS-SEM, either a reflective or formative measurement model can be adopted. This study adopted a formative measurement model to analyse the mediation effect of trust on willingness to pay for health insurance. The model was formatively measured because each indicator explicitly captured the constr...
is different. If you’re in the Sacramento region, even the attitudes of the growers [are] different from [those] in the San Joaquin. So you really have to understand the entire ecosystem.” Given the unique nature of each farm and region, long years of experience, hard-earned knowledge,...
Trust region reflectiveIn this paper, a semi-analytical elastodynamic forward solver was proposed for the Multichannel Analysis of Surface Waves (MASW) using the spectral element technique for the first time. A root finding method based on Brent's algorithm was proposed to accurately extract the ...
