Writer Identification Using Inexpensive Signal Processing Techniques
We propose to use novel and classical audio and text signal-processing and
otherwise techniques for "inexpensive" fast writer identification tasks of
scanned hand-written documents "visually". The "inexpensive" refers to the
efficiency of the identification process in terms of CPU cycles while
preserving decent accuracy for preliminary identification. This is a
comparative study of multiple algorithm combinations in a pattern recognition
pipeline implemented in Java around an open-source Modular Audio Recognition
Framework (MARF) that can do a lot more beyond audio. We present our
preliminary experimental findings in such an identification task. We simulate
"visual" identification by "looking" at the hand-written document as a whole
rather than trying to extract fine-grained features out of it prior
classification.Comment: 9 pages; 1 figure; presented at CISSE'09 at

Machine-Related Backgrounds in the SiD Detector at ILC
With a multi-stage collimation system and magnetic iron spoilers in the
tunnel, the background particle fluxes on the ILC detector can be substantially
reduced. At the same time, beam-halo interactions with collimators and
protective masks in the beam delivery system create fluxes of muons and other
secondary particles which can still exceed the tolerable levels for some of the
ILC sub-detectors. Results of modeling of such backgrounds in comparison to
those from the e+ e- interactions are presented in this paper for the SiD
detector.Comment: 29 pages, 34 figures, 7 table
