Abstract Flexible robots with controllable mechanisms have advantages over common tandem in vibration magnitude, residual time, working speed, and efficiency. However, abnormal can sometimes occur, affecting their operation. Traditionally only simple are considered studying vibration, omitting reference to important chaotic phenomena caused by the flexibility of mechanism rod. In order better u...

The key operational feature that gives Kipling its power is the way that it partitions multivariate space rather than the execution of complex algorithms or computations. The original inspiration for Kipling.xla was the CMAC (Cerebellar Model Arithmetic Computer), originally designed by Albus (1975) for robotic systems and still widely used today. The CMAC design subdivides variable space into ...

A field experiment in Yokohama (Japan) reveals that a macroscopic fundamental diagram (MFD) linking space-mean flow, density and speed exists on a large urban area. The experiment used a combination of fixed detectors and floating vehicle probes as sensors. It was observed that when the somewhat chaotic scatter-plots of speed vs. density from individual fixed detectors were aggregated the scatt...

We consider an axi-symmetric flexible rotor perturbed by dissipative, conservative, and non-conservative positional forces originated at the contact with the anisotropic stator. The Campbell diagram of the unperturbed system is a mesh-like structure in the frequency-speed plane with double eigenfrequencies at the nodes. The diagram is convenient for the analysis of the traveling waves in the ro...

The speed-traffi c fl ow density interdependence diagram has a number of varia ons, star ng with the theore cal model, through various empirical models that were developed and models based on actual research done on traffi c fl ow. The func onal interdependence is obtained using the Sugeno fuzzy logic system, where representa ve values proposed in HCM 2010 have been adopted as parameters of out...

We study numerically the behavior of the Biham-Middleton-Levine traffic model in three dimensions. Our extensive numerical simulations show that the phase diagram for this model in three dimensions is markedly different from that in one and two dimensions. In addition to the full speed moving as well as the completely jamming phases, whose respective average asymptotic car speeds (v) equal one ...

This article presents particle swarm optimization (PSO)-based optimal gain tuning of proportional integral (PI) speed controller in an induction motor (IM) drive (30 hp) with mine hoist load diagram. Optimization considers the load and speed variations, and provides appropriate gains to the speed controller to obtain good dynamic performance of the motor. IM performance is checked with the opti...

It is an outstanding open problem of computational geometry to prove a nearquadratic upper bound on the number of combinatorial changes in the Voronoi diagram of points moving at a common constant speed along linear trajectories in the plane. In this note we observe that this quantity is Θ(n) if the points start their movement from a common line.
