The free vibration of a fluid/structure system consisting of a cylindrical blockage submerged in a liquid enclosed by a cylindrical shell is investigated for the purpose of pipe line transportation monitoring. The wavenumbers are obtained and the reflection and transmission characteristics of these waves at the blockage interfaces are investigated theoretically. Reflection and transmission rati...

Congestion is a problem in order-picking-systems. We developed CTMC models to represent picker blocking in cases including pickers with different exponentially distributed picking times and k pickers, for narrow and wide aisle systems. The focus was not to produce an all-inclusive model, but to generate models that give designers insight of the system, allowing them to reduce the number of vari...

One of the most prevalent causes failure for a ventriculoperitoneal shunt is blockage, other being infection. This study looks at blockage valve, and whether occlusion valve accelerated by presence an assumes that infection will raise number white blood cells contained in cerebrospinal fluid to fight it thus accelerate occlusion. The experiment simulates system suspending water bath has tempera...

In this letter, we address blockage detection and precoder design for multiple-input multiple-output (MIMO) links, without communication overhead required. Blockage is achieved by classifying light ranging (LIDAR) data through a physics-based graph neural network (GNN). For design, preliminary channel estimate obtained running ray tracing on 3D surface from LIDAR data. This successively refined...
