Abstract A thermoelectric generation (TEG) system has the weakness of relatively low conversion efficiency caused by heterogeneous temperature distribution (HgTD). Dynamic reconfiguration is an effective technique to improve its overall energy under HgTD. Nevertheless, numerous combinations electrical switches make dynamic a complex combinatorial optimization problem. This paper aims design novel adaptive coordinated seeker (ACS) based on optimal configuration strategy for large-scale TEG...
Summary Fast and precise identification of several unknown parameters for solid oxide fuel cell (SOFC) models play a critical role in modeling analysis, optimal control, behavior prediction. However, inherent high‐nonlinear, multi‐variable, strongly coupled features usually lead to thorny obstacles that hinder conventional methods identify them with high speed, accuracy, reliable stability. Hence, Levenberg‐Marquardt backpropagation (LMBP) algorithm‐based parameter technique is proposed this...

Hence, an adaptive compass search (ACS) algorithm employed...
Comprehensive Summary Tetralin‐1‐carboxamides are frequently incorporated in myriad medicinally important molecules. However, their existing synthetic routes not only suffer from some drawbacks such as tedious procedures, harsh reaction conditions, narrow substrate scope, low yields, and environmental problems, but also based upon the elaboration of uneasily available non‐linear tetralin derivatives.
