In this paper, we compare a multi-round, second-price, sealed-bid bundle auction and a single-item, sequential, second-price, sealed-bid auction for berth slot leasing for vessels (roll-on/roll-off passenger vessels and/or cruise ships) at a public marine terminal.The bundle auction mechanism is designed to maximize port operator profits by auction

In this paper, we continue to build an ultra-high speed laser schlieren testing system on the self-developed mesoscale explosion pipeline to explore the flame propagation characteristics of nitrogen and carbon dioxide inhibiting gas/air premixed gas deflagration under different injection positions and pressures.The results show that: in the experim

Fingerprint recognition is an important tool for personal identification due to its versatility, user-friendliness, and accuracy.Fingerprint orientation field estimation, a crucial step in fingerprint feature extraction, significantly impacts recognition performance.While numerous methods have been proposed, achieving state-of-the-art accuracy ofte

Relevance of the discussed issue.Irbit diatomite deposit is one of the largest in the Russian Federation and in Trans-Urals region and it is currently used for production of low value-added goods.Despite the long history Drinkware of industrial exploration, the comprehensive studies of the material composition of Irbit diatomites were never held, c

A critical question among the researchers working on fungal lipid biology is whether the use of an enriched growth medium can affect the lipid composition of a cell Parts and, therefore, contribute to the observed phenotypes.One presumption is that enriched medias, such as YPD (yeast extract, peptone and dextrose), are likely to contain lipids, whi
