Development and Operational Status of Pf-ring and Pf-ar
The Photon Factory storage ring (PF-ring) and the Photon Factory advanced ring (PF-AR) continue a stable user operation as a synchrotron radiation source. The MTBF of the PF-ring has been kept at high around 200 h. At the PF-ring, a top-up operation started in April 2009. A rapid-polarization-switching device consisting of tandem polarizing undulators and a new injection system using a pulsed s...
متن کاملThe New Bpm System and Its Commissioning at Pf Ring
We describe the new beam position monitor (BPM) system built for the brilliance-upgraded Photon Factory storage ring. The new system was designed to enable precise and fast measurements to correct the closed orbit distortion (COD), as well as to feed back the orbit position during user-runs. There are 42 BPMs newly installed, amounting to a total of 65 BPMs. All of the newly installed BPMs are ...
متن کاملThe PF STAR Children’s
This paper describes the corpus of recordings of children’s speech which was collected as part of the EU FP5 PF STAR project. The corpus contains more than 60 hours of speech, including read and imitated native-language speech in British English, German and Swedish, read and imitated non-nativelanguage English speech from German, Italian and Swedish children, and native-language spontaneous and...
متن کاملImprovement to the PF
The PF algorithm, discussed in HD92], computes changes to a materialized view when the underlying base relations change. The algorithm considers each changed base relation in turn and propagates the changes to the derived relations. We propose ways of making this propagation process eecient by exploiting stratiication Ull89] of programs and by storing and reusing some of the information derived...
متن کاملScrambling and the PF Interface
1. Introduction The position in which an argument is projected is usually assumed to be determined strictly by conditions of the computational system (X-bar theory) and the LF interface (Θ-theory). We will argue that these systems, although they obviously restrict the distribution of arguments, still allow in many cases a range of positions in which a given argument can be generated (merged). I...
