We consider a variant of the berth allocation problem—that is, multiport problem—aimed at assigning berthing times and positions to vessels in container terminals. This involves optimizing vessel travel speeds between multiple ports, thereby exploiting potentials collaboration carriers (shipping lines) terminal operators. Using graph representation problem, we reformulate an existing mixed-inte...

A physical model of gabion overflow dams was studied to determine the velocity profile and Reynolds shear stress. Physical tests were done under two different conditions of dam crest, overflow dams with impermeable and with permeable crests. Instantaneous velocity components over dam crest were measured by an ADV (Acoustic Doppler Velocimeter) instrument. This instrument is capable of measuring...

there are various ways for estimating velocity of money in economic literature and each has its own specific weaknesses and strengths. particularly, since a great deal of financial innovations and changes have recently taken place affecting the velocity of money, many traditional methods can no langer calculate the equilibrium velocity of money, and they are no longer dependable from the econom...

This paper sheds light on the effect of combination modes evaluation berthing capacity for Sanya Yazhou Fishing Port (SYFP) under hypothetical typhoon conditions. By statistically analysing maximum probability moving speeds and directions historical typhoons passing through fishing port, representative path was determined with nonparametric regression method. The designed wind fields levels 12–...

conclusions the results showed that the heat stress increased by increasing air velocity and humidity in both groups. the air velocity with high humidity can be considered as a positive factor in the occurrence of heat strain. therefore, the incidence of heat stress decreases with the increase of humidity and reduction of air velocity or with increase of air velocity and reduction of humidity i...
