A new method for on-line phase space measurements with kicker excitation at COSY was developed. The position data were measured using the analog output of two beam position monitors (BPMs) and directly monitored on a digital storage oscilloscope with an external clock (bunch-synchronous sampling). Nonlinear behavior of the proton beam was visible as well as were resonance islands. Typical measu...

This paper discusses on-line estimation of rotor body parameters of the synchronous hydro-generator under saturated condition. A new model of the saturated synchronous salient-pole machine, based on the saturated synchronous inductances which are estimated from measured steady-state operating data, is presented. Using this model the excitation disturbance responses of the saturated synchronous ...

In this paper, an efficient and comprehensive hybrid intelligent technique for the optimal placement of phasor measurement units (PMUs) is proposed to minimize the number of PMU installation subjected to full network observability. Three main purposes of PMUs output synchronous measurements are monitoring, control, and protection of power system. We have combined Binary Imperialistic Competitio...

paragangliomas in the head and neck are found typically in the region of the carotid body, jugular body, and along the 9th and 10th cranial nerves. they can occur in multicenteric forms, but generally, laryngeal paragangliomas are not found in these patients. only two cases of laryngeal paraganglioma have been reported with a synchronous lesion elsewhere. we report an additional case of a 34-ye...

A description is given of the application of the Synchronous Detector technique for eleciroretinographic (ERG) measurements (cone function) in patients with retinitis pigmentosa. The results obtained, in terms of average amplitudes and average "delay time," are compared with the results obtained by conventional waveform averaging processes. Time delay measurements with the Synchronous Detector ...

The problem of indoor navigation using pseudolites is investigated and two different approaches, employing synchronous and asynchronous technologies, are considered. It is shown that synchronous pseudolite systems, commonly considered more accurate, seem to be unsuitable for deep indoor operations: in complex propagation environments, the synchronization required for metre level navigation is d...
