HIGH SCHOOL WILL START AT 8:15 AM this September in Duxbury, Mass, a Boston suburb, instead of at 7:30 AM, as it did last year. School officials hope the 45-minute delay will allow the 1000 students in grades 9 through 12 to sleep longer and arrive at school more alert and ready to learn. In the past decade, at least 80 US school districts have delayed their high school start times, and perhaps...

The rhinoviruses were the most recently described agents to be sought in the MRC/PHLS studies. Not until 1960 was a practical routine method for their detection described (Tyrrell & Parsons, 1960) with the result that, at the commencement of the studies in October 1964, few reports were available based on a substantial number of isolates. However, rhinoviruses had been shown to be associated wi...

What makes a rhythm interesting, or even exciting to listeners? While in the literature a wide range of definitions of syncopation exists, few allow for a precise formalization. An exception is Longuet-Higgins and Lee (1984), that proposes a formal definition of syncopation. Interestingly, this model has never been challenged or empirically validated. In this paper the predictions made by this ...

In this paper, we consider an  i.e., multiple step-stress accelerated life testing (ALT) experiment with unequal duration of time . It is assumed that the time to failure of a product follows Rayleigh distribution with a log-linear relationship between stress and lifetime and also we assume a generalized Khamis-Higgins model for the effect of changing stress levels. Taking into account that the...

This project implements a method, presented by Longuet-Higgins and Cokelet, for modeling the breaking of ocean waves. Five waves are generated, with the same shaped profile but different amplitudes. Their behavior over time is compared, and it is seen that higher amplitude waves break faster and with a sharper point. Additionally, a variable S is calculated to measure the surfability of these w...
