Optics parameters at the interaction point, beta, x-y coupling, dispersion and their chromatic aberrations, seriously affect the beam-beam performance as is shown in experiments and simulations. The control of the optics parameters is essential to maintain the high luminosity in KEKB. They drift day by day, or before and after the beam abort. They were often monitored at intervals of the operat...

Most existing Global Positioning System (GPS)-based vehicle navigation systems (also termed route guidance systems) utilize distance within their turn-by-turn navigation directions. For example, a system might give a voice instruction like ”turn left in 0.2 mile”. However, human drivers usually use landmarks to help their navigation. Some previous research has shown that there are performance-r...

Ionization profile monitors (IPMs) are installed in the Fermilab Booster, Main Injector and Tevatron. They are used routinely for injection matching measurements. For emittance measurements the IPMs have played a secondary role to the Flying Wires, with the exception of the Booster (where it is the only profile diagnostics). As Fermilab is refocusing its attention on the intensity frontier, non...

This paper presents an automatic speech recognition (ASR) system dedicated for meetings of the National Congress of Japan. The distinctive features of the congressional meeting speech are wide distribution and frequent change of topics. For more accurate transcription, such topics should be emphasized in a language model one after another. Therefore, we introduce two approaches for topic adapta...

We report on tests of an x-ray beam size monitor based on coded aperture imaging[1]. This technique uses a mask pattern to modulate incoming photons, with the resulting image being deconvolved through the mask and detector responses, including the effects of diffraction and attenuation materials in the path, over the spectral and angular distribution of the synchrotron radiation generated by th...

This paper describes the first of two experiments examining the safety and usability of the Siemens Ali-Scout navigation system, an in-vehicle interface that provides turn-by-turn visual and voice guidance. A total of 54 drivers varying in age drove an instrumented car to four destinations, twice using the Ali-Scout and, subsequently, once using experimenter verbal guidance. Subjects were teste...
