This paper addresses the fundamental problem of relating the anthropometry of the pinna to the localization cues it creates. The HRTFs for isolated pinnae (which are called PRTFs) are analyzed and modeled for sound sources directly in front of the listener. It is shown that a low-order filter model, with parameters suggested by or derived from pinna anthropometry, provides a good fit to the dat...

Many obstetricians in this country are still not in favour of external cephalic version (ECy). This is despite the various studies in recent years that have shown its effectiveness in reducing the incidence of vaginal breech delivery and Caesarean section for breech presentation1,2,3,4,5. This study is a prospective observational study on the outcome of 80 cases of external cephalic version at ...

We initiate the study of sublinear-time algorithms in the external memory model [14]. In this model, the data is stored in blocks of a certain size B, and the algorithm is charged a unit cost for each block access. This model is well-studied, since it reflects the computational issues occurring when the (massive) input is stored on a disk. Since each block access operates on B data elements in ...

Sequential selection has been solved in linear time by Blum e.a. Running this algorithm on a problem of size N with N > M , the size of the mainmemory, results in an algorithm that reads and writes O(N) elements, while the number of comparisons is also bounded by O(N). This is asymptotically optimal, but the constants are so large that in practice sorting is faster for most values of M and N . ...

The capability approach of Amartya Sen evaluates well-being in terms of an individual’s achievements and abilities to function. The traditional view of capabilities is that they are discernable as part of an individual’s own set of characteristics, or as part of a package of socially provided services. We argue that individuals also have access to a broad array of capabilities through their fam...
