Wear analysis has been carried out on aluminum tube in parallel triangular tube bundle with P/D ratio of 1.45 and the baffle plate placed at the mid-span of the bundle.The cross-flow velocity of water ranges from 0.18 m/s to 0.55 m/s.For each flow velocity, tests were performed on five different flow velocities and three-time spans Rests (tube-baff
Abstract Background Continuing research into the global multiple sequence alignment problem has resulted in more sophisticated and principled alignment methods.Unfortunately these new algorithms often require large amounts of time and memory to run, making it nearly impossible to run these algorithms 143 on large datasets.As a solution, we present
Flexure hinges are widely used for very high precision mechanisms, such as a high precision linear guide, a nano positioning stage, a robot hand and etc., because of no gap and no friction.Regarding circular hinge stiffnesses, Paros and Weisbord derived exact solutions, but they are unwieldly because of the complexity.Simpler equations are preferre
Abstract Truck travel time prediction is the basis for real-time optimal scheduling decision of open-pit trucks.Most prediction models for open-pit truck travel time mainly rely on a single machine learning algorithm or model to optimize the hyperparameters, which is difficult to accurately capture the composite characteristics of truck travel time
Monetary National Income Analog Computer (MONIAC) is a hydraulic machine that we can describe as an analog simulator modeling macroeconomic relationships.It was invented by the famous economist A.W.Phillips in 1949 and produced in limited numbers.The circulation of water in the machine shows the circulation of money in the economy.The economic beha
