Two crucial aspects of the data processing of the recently proposed DIGISTAR II and DIGISTAR III multiple field-of-view (FOV) star trackers, which use one/two mirrors deflecting the sensor FOV to two/three orthogonal directions, respectively, are here analyzed. These aspects are the star identification process and the estimation of the mirror misalignment. In particular it is shown how to adapt...

The secondary stress pattern of Spanish occupies a key position in current debates in metrical stress theory. It is one of the patterns potentially capable of discriminating between accounts where distance-sensitive alignment constraints play a central role (McCarthy and Prince 1993, Gordon 2002, Hyde 2002) and accounts where they play a more restricted role (Alber 2005) or no role at all (Kage...

Time-series MRI data often suffers from image misalignment due to patient movement and respiratory and other physiologic motion during the acquisition process. It is necessary that this misalignment be corrected prior to any automated quantitative analysis. In this article a fast and automated technique for removing in-plane misalignment from time-series MRI data is presented. The method is com...

Acoustic Emission (AE) is being extensively used as a Non Destructive Technique (NDT) for diagnosis of rotating components. The main theory behind this diagnosis is that while rotation, acoustic energy level of defective portion in rotating element is different. In the present study a signal processing technique is proposed to identify the variation in acoustic signal and results are verified f...

Many cities in the Global South are structurally different from Northern, particularly American, on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them terms a standard vocabulary risks imposing an inappropriate way seeing. We need that is able to accommodate their experience.
