This paper presents a magnetic tumbling microrobot design at the micro-scale. The microrobot has a dumbbell shape whose largest dimension is about 400 μm. When subjected to an exterior predefined magnetic field, the magnetic microagent performs a tumbling motion driven by the interacting magnetic forces and momentums. The magnetic field providing driven force is generated by a coil system consi...

Control chart techniques have been widely used in industries to monitor a process in quality improvement. Whenever we deal with variables data, we usually employ a combination of X-bar chart and R chart (or S chart) to monitor both the center and the spread of the process. In this paper, we propose a simple alternative, that is, we design a single chart to monitor both the center and the spread...

abstract. in recent years several studies have shown that  control charts with adaptive schemes or double sampling plans detect both small and moderate shifts in the process mean more quickly than the traditional shewhart  chart. in the classical double sampling  chart, the difference between two points were placed in the central region of first stage was not considered. in this study, a new co...

Run-and-tumble particles, frequently considered today for modeling bacterial locomotion, naturally appear outside a biological context as well. Here, we consider them in quantum mechanical relation, using wave function to drive their propulsion and tumbling. Such quantum-active motion realizes jittery of Dirac electrons (as the famous Zitterbewegung): electron is run-and-tumble particle, where ...
