In this paper, we studied the performance of the iterated Viterbi detection methods using the multi-track multi-head processing for a bit patterned media (BPM) channel with a two-dimensional interference consisting of inter-symbol interference (ISI) and inter-track interference (ITI). In each method, three Viterbi detectors are employed to process the three readback signals. In their trellises,...

Outreach projects are often used to a limited extent for dissemination purposes and rarely have significant impact on the student’s teaching technical skills. The RadioLab project requires proactive interaction between researchers students by experimental activities measuring environmental radioactivity, in particular radon gas. Buildings considered be of radiological interest, such as schools,...

We describe a high speed imaging system that is used to track tracer particles in highly turbulent flows. The system uses silicon strip detectors designed for high energy physics experiments and is capable of reading two detectors at a frame rate of 70 kHz. Each detector contains 512 strips and measures a one-dimensional projection of the light striking it. The position measurements from this s...

We present an expression for the covariance matrix of the set of state vectors describing a track fitted with a Kalman filter. We demonstrate that this expression facilitates the use of a Kalman filter track model in a minimum χ2 algorithm for the alignment of tracking detectors. We also show that it allows to incorporate vertex constraints in such a procedure without refitting the tracks.

The e ects of stirring on the bulk etch rate of LR 115 detector has been investigated. The surface pro6le measurement method using an instrument called Form Talysurf has been used to measure the thickness of the active layer of the LR 115 detectors. The etchant was 10% aqueous solution of NaOH maintained at 60◦C. The bulk etch rate under magnetic stirring has been found to be 6:65 ± 0:34 m h−1 ...
