A circuit model for open-loop compensation of hysteresis
2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016Hysteresis is a nonlinear phenomenon useful whenever memory is required, but that can become annoying in applications where linearity is desired. In these cases, a possible way to reduce the inconvenience is to compensate the undesired memory effect by pre-processing the input signal through the hysteresis inverse model. In this paper, the inverse of a

Model-in-the-Loop Track Simulation
SAE Technical Paper Series, 2006<div class="htmlview paragraph">Model-in-the-loop (MiL) testing refers to the scenario in which the test specimen is part real and part virtual, i.e. a physical sub-system is linked to a real-time computer simulation. Due to imperfect actuator behavior the hybrid test specimen will not respond in quite the same way as the real (complete) specimen

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2006
Physical testing is used extensively to characterize mechanical systems. However, in many cases, mathematical models are now available that adequately describe the behaviour of part of the test specimen. Thus, test systems can be conceived which split the specimen into a physical part, and a virtual part, i.e. a real-time computer simulation.

Computational Models for Cardiac Looping
Advances in Bioengineering, 1996Abstract Early in development, the initially straight heart tube bends (loops) into a curved tube. Two theoretical models are proposed for the mechanism of cardiac looping. In one model, a residual stress in the dorsal mesocardium drives looping, while in the other model, microfilament contraction drives the deformation. The results show

Full 3D Electromagnetic Modeling of Inductive Loops
2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018Inductive loop sensors are a highly regarded element of computerized automatic traffic control for their simplicity, robustness, and ease of installation. Traditionally they have been used to detect speed, acceleration and count vehicles. More recently inductive loops have been employed to recognize types of vehicles.

3D City Modeling Using Cognitive Loops
Third International Symposium on 3D Data Processing, Visualization, and Transmission (3DPVT'06), 20063D city modeling using computer vision is very challenging. A typical city contains objects which are a nightmare for some vision algorithms, while other algorithms have been designed to identify exactly these parts but, in their turn, suffer from other weaknesses which limit their application.

A dynamical model of prominence loops
Solar Physics, 1989A dynamical model of prominence loops is constructed on the basis of the theory of hydromagnetic buoyancy force. A prominence loop is regarded as a flux rope immersed in the solar atmosphere above a bipolar region of the photospheric magnetic field. The motion of a loop is partitioned into a translational motion, which accounts for the displacement of ...

On the stability of a linear bioprocess model with recycle loop
IEEE Transactions on Automatic Control, 2005In this note, we treat a linear bioprocess model with recycle loop and analyze the spectrum of the closed-loop operator in order to discuss the exponential stability. It is shown that a C/sub 0/-semigroup generated by the closed-loop operator satisfies the spectrum determined growth assumption and that the recycle loop works effectively for the process

Formal Model In-The-Loop for Secure Industrial Control Networks
2022Current trends of digitalization are becoming significantly prevalent within the field of industrial control systems. While in recent history a typical industrial control system would have been isolated with rudimentary ways of extracting data, nowadays it is becoming expected that the control system could not only provide large amounts of data over ...

A Computational Model for Gut Looping
ASME 2010 Summer Bioengineering Conference, Parts A and B, 2010In chick embryos, a series of complex invaginations involving the three germ layers (endoderm, ectoderm, and mesoderm) lead to the formation of the primitive gut tube. This process normally occurs during the third day of development, at the end of which the gut appears as an open cylindrical tube (Fig.1A).
