The intense bunch which is called for in the muon collider design will be subject to transverse instability. It has been suggested that tune spread due to BNS damping be used to control the instability. The transverse dynamics in a 50GeV 50GeV muon collider ring is examined numerically using a broad-band impedance. In addition to the BNS damping, tune spreads due to chromaticity, amplitude depe...

The flagellated bacterium Escherichia coli is increasingly used experimentally as a self-propelled swimmer. To obtain meaningful, quantitative results that are comparable between different laboratories, reproducible protocols are needed to control, 'tune' and monitor the swimming behaviour of these motile cells. We critically review the knowledge needed to do so, explain methods for characteris...

In this paper, a self-tuning fuzzy controller with a smart and easy structure is presented. The tuning schemes allow us to tune the scaling factors by only seven rules. The aim of a controller is to obtain a satisfactory performance, such as the rise time, the overshoot, the steady-state error for the step response. Simulation results of a third order system with time-delay show a better perfor...

The present work is concerned with relay auto tuning of parallel cascade controllers. The method proposed by Srinivasan and Chidambaram [10] to analyze the conventional on-off relay oscillations for a single loop feedback controller is extended to the relay tuning of parallel cascade controllers. Using the ultimate gain and ultimate cross over frequency of the two loops, the inner loop (PI) and...

A digital receiver based tune measurement system is implemented recently. Novel digital receiver plays a central role for tune measurement. The output of digital receiver is further Fourier analysis by digital signal processor. Design considerations of this tune monitor such as, speed, resolution, dynamic range, control interface will discuss in this report. Comparing with traditional spectrum ...

We demonstrate ultrastrong and flexible hydrogels by self-assembling chitin nanofiber in the presence of gelatin methacryloyl. We tune the mechanical properties of the hydrogel with chitin nanofiber content and show proof-of-concept applications in engineering vascular tissue.

Despite the application of advanced control technique to improve the performance of electro-hydraulic position control, Proportional Integral Derivative (PID) control scheme seems able to produce satisfactory result. PID is preferable in industrial applications because it is simple and robust. The main problem in its application is to tune the parameters to its optimum values. This study will l...
