In this paper, the acoustic-perceptual effects of air sacs are investigated. Using an adaptive hearing experiment it is shown that air sacs reduce the perceptual effect of vowel-like articulations. Air sacs are a feature of the vocal tract of all great apes, except humans. Because presence or absence of air sacs is correlated with the anatomy of the hyoid bone, a probable minimal and maximal da...

This study aimed to quantify the variability of walking in young adults across measurement sessions held at varied time intervals. Inconsistent marker placement, a major source of variation in gait measurement, was minimized in this study in order to quantify how much variation is attributable to participants naturally altering their walking. Three-dimensional gait data were captured from five ...

Skin on the foot sole plays an important role in postural control. Cooling the skin 23 of the foot is often used to induce anaesthesia to determine the role of skin in motor and 24 balance control. The effect of cooling on the four classes of mechanoreceptor in the skin is 25 largely unknown and thus the aim of the current study was to characterize the effects of 26 cooling on individual skin r...

The rectilinear polygon cover problem is one in which a certain class of features of a rectilinear polygon of n vertices has to be covered with the minimum number of rectangles included in the polygon. In particular, we consider covering the entire interior, the boundary and the set of corners of the polygon. These problems have important applications in storing images and in the manufacture of...

The purpose of this paper is to complement the characterization of patient-specific carotid artery bifurcation hemodynamics based on image data obtained by Doppler ultrasound imaging. A methodology for patient-specific 3D luminal surface reconstruction followed by structured hexahedral meshing of the volume and blood flow simulation is presented. Quantitative descriptors of the flow based on wa...

The combination of an agile or incremental approach with the implementation of Enterprise System (ES) is seen as a kind of catch 22. Vendors and implementers nevertheless lately tend to adhere to cyclical approaches with shortened implementation times. This way of working more and more approaches the incremental philosophy, but also influences the requirements on how the implementation process ...

Using Amdahl's law as an instrumentation guide we illustrate a technique for developing e cient code on Massively Parallel Processor (MPP) performance-class networks to solve nontrivial, high performance scienti c problems. We also show the importance of collective communication within the Message Passing Interface (MPI) paradigm for some applications. Given the popularity of Beowulf-like clust...

Research finds police-led crime control interventions focusing on places and involving partnerships tend to yield positive crime control outcomes. Some scholars argue that these positive outcomes are achieved when police use place-based, partnership-oriented interventions to facilitate and encourage collective efficacy (CE). The corollary being that these CE-enhancing efforts lead to less crime...
