Ebook "Measurement and control of charged particle beams" we have tried to coherently organize this material so as to be useful to designers and operators in the commissioning and operation of particle accelerators. A point of emphasis has been to provide, wherever possible, experimental data to illustrate the particular concept under discussion. Of the data pre­ sented, most are collected from presently existing or past accelerators and we regret the problem of providing original data some of which appear in less accessible publications - for possible omissions we apologize.

In this paper, we propose a method that uses the non-uniform Fast Fourier Transform (FFT) to compensate for Doppler frequency shifts in orthogonal frequency division multiplexing (OFDM) based underwater acoustic (UWA) communication systems. To estimate the Doppler frequency shift, the paper proposes using a pilot carrier frequency (PCF) that is identified by transmitting with greater power in the frequency domain compared to other subcarriers.

The present study investigates the axial vibration of double-walled nanotubes. Using the nanorod continuum model with the van der Waals effect, the vibrational frequencies are studied. Aydogdu (Journal of Vibration and Control, Vol. 21, Issue 16, (2015), 3132-3154) proposed a reliable model for the study of axial vibration in a double-walled nanotube.

This paper focuses on a method of designing PD controller for a balancing robot-cart. The uncertainty of model parameters was introduced as constraints in state space. PD controller was designed through choosing Lyapunov function which was transformed by Kalman-Yakubovich-Popov lemma, a basic theoretical method based on frequency criterion.
