We report on the status of emittance tuning techniques at the CESR Test Accelerator (CesrTA). The CesrTA experimental program requires that we operate in a variety of machine lattices, each with the smallest possible emittance. We utilize high-bandwidth BPM electronics for fast, precision measurements of orbit, betatron phase, transverse coupling, and dispersion. Analysis of the data and implem...

The surveillance game [Fomin et al., 2012] models the problem of web-page prefetching as a pursuit evasion game played on a graph. This two-player game is played turn-by-turn. The first player, called the observer, can mark a fixed amount of vertices at each turn. The second one controls a surfer that stands at vertices of the graph and can slide along edges. The surfer starts at some initially...

Recently, many web services to provide information for public transport are developed and released. They are optimized for mobile devices such a smartphone. We are also developing better path planning system for route buses and trains called “Bus-Net”[1]. However these systems only provide paths and related information before the user start moving. So we propose a context aware navigation to ch...

The coherent beam-beam interaction in the absence of Ladau damping is studied with a computer simulation of four, space-charge compensate colliding beams. Results are presented for the modes, phase space structures, widths, and growth rates of coherent beam-beam resonances. These results are compared with solutions of the Vlasov equation, and with measurements made at the DCI storage ring which...

For the stable high-luminosity operation and luminosity-increase, the electron and positron storage rings of the KEK B-Factory (KEKB) is equipped with various beam instrumentations, which have being working well since the start of the commissioning in December, 1998. Details and performance of the beam-position monitor system based on the spectrum analysis using DSPs, the turn by turn BPM with ...

We propose to generate steady-state microbunching in a storage ring with a reversible seeding scheme. High gain harmonic generation (HGHG) and echo-enabled harmonic generation (EEHG) are two promising methods for microbunching linac electron beams. Because both schemes increase the energy spread of the seeded beam, they cannot drive a coherent radiator turn-by-turn in a storage ring. However, r...

ITE JOURNAL / SEPTEMBER 1998 MANY URBAN AND SUBURBAN arterials are congested with little immediate hope of relief. Access management and better coordination between land use and transportation offer long-term hope for developing areas but little short-term promise for developed areas. Transportation engineers in many places have done as much as they can with actuated signals, signal systems, mu...

LINK TO PAPER The Road Ahead: Using ArcPad Maps in Census Bureau Field Activities Track: Census and Geo-Demographics Author(s): Andrea Johnson The Census Bureau is exploring the feasibility of using handheld census computers in future enumeration activities. Recently, in Sussex Co DE, the Census Bureau tested the feasibility of using maps on hand-held computer and the increases in productivity ...

An important difference exists between the way humans communicate route knowledge and the turn-by-turn route directions provided by the majority of current navigation services. Navigation services present route directions with the same amount of detail regardless the route segment’s significance in the instructions, user’s distance from the destination, and finally the level of user’s familiari...

1 Introduction " Before there were computers, we could distinguish persons from non-persons on the basis of an ability to participate in conversations. But now, we have hybrids operating between person and non persons with whom we can talk in ordinary language. " (Colby 1999). Human machine conversation as a technology integrates different areas where the core is language, and the computational...
