The inbound container space allocation in the automated container terminals

Expert Systems with Applications, 2021
Abstract In this paper, we study an inbound container space allocation problem in the automated container terminals using simulation-embedded optimization. We aim to allocate the container terminal yard space for a batch of arrived inbound containers so as to minimize the total AGV (Automated Guided Vehicle) waiting time in the space allocation ...

Automated Carboxy-Terminal Sequence Analysis of Polypeptides Containing C-Terminal Proline

Analytical Biochemistry, 1995
Proteins and peptides can be sequenced from the carboxy-terminus with isothiocyanate reagents to produce amino acid thiohydantoin derivatives. Previous studies in our laboratory have focused on automation of the thiocyanate chemistry using diphenyl phosphoroisothiocyanatidate (DPP-ITC) and pyridine to derivatize the C-terminal amino acid to a ...
