The Diamond booster and storage ring are equipped with Libera Electron Beam Position Processors with turnby-turn capabilities. We describe here the turn-by-turn data acquisition system and the software used for postprocessing the beam data. The signals from the Libera boxes are acquired and controlled with EPICS and then transferred to the MATLAB environment via the MATLAB Channel Access or Lab...

A turn-by-turn vertical beam profile monitor has been developed at the Cornell Electron Storage Ring (CESR). The instrument optically images the vertical beam distribution with an array of optical fibers that transport visible synchrotron radiation to an array of photo-multiplier tubes. Each PMT signal is recorded by a turn-by-turn data acquisition system. With this instrument, we compare profi...

Models with a time delay often occur, since there is a naturally occurring delay in the transmission of information. A model with a delay can be noninvertible, which in turn leads to qualitative differences between the dynamical properties of a delay equation and the familiar case of an ordinary differential equation. We give specific conditions for the existence of noninvertible solutions in d...

As radio signals are propagated through the atmosphere, they are affected mostly by variability in refractive index which, in turn, leads to a decrease in their speed of propagation. This will eventually bring about a delay called propagation delay . Propagation delay could be viewed in various forms, but this paper has concentrated on ionospheric and tropospheric propagation delays. These dela...

The measurement of the range (or actually delay time) performed by an altimeter is affected by the delay of the ionosphere. This delay is in turn dependent on the frequency used. One of the major innovations of RA-2 is the second channel, at S-band (3.2 GHz), that provides the altimeter with the ionospheric correction This paper describes the characteristics of the S-band channel in RA-2, the u...

Unlike most existing studies on off-ramp traffic signal control, this paper focuses on the optimization problem of the signalized intersection connected to freeway on-ramps. Conflicts are often observed between the traffic heading to an onramp and the traffic continuing straight which leads to issues such as intersection overflow, increased delay, and concerns about safety. For studying this pr...

We investigate the relationship between several enumeration complexity classes and focus in particular on the incremental polynomial time and the polynomial delay (IncP and DelayP). We prove, modulo the Exponential Time Hypothesis, that IncP contains a strict hierarchy of subclasses. Since DelayP is included in IncP1, the first class of the hierarchy, it is separated from IncP. We prove for som...
