Quantification of rheological parameters in deep‐sea mining plumes
Deep Underground Science and Engineering, Volume 5, Issue 1, Page 250-265, March 2026.This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

Real-time evolution of an embedded controller for an autonomous helicopter [PDF]
, 2008 In this paper we evolve the parameters of a proportional, integral, and derivative (PID) controller for an unstable, complex and nonlinear system. The individuals of the applied genetic algorithm (GA) are evaluated on the actual system rather than on a ...

Engineering Reports, Volume 8, Issue 3, March 2026.From the reviews, a new concept of a low‐speed centrifugal pump (LSCP) driven by a vertical ultra‐low‐head hydro turbine (VULHT) was designed and tested on simulation and physical setup. It was performed with a 1.8 m delivery head, concluding as inefficient. For ultra‐low‐head conditions, different than centrifugal action is recommended.
