This paper describes an experimental alerting system under development by the Australian Bureau of Meteorology, initially targetted at (but not restricted to) the aviation sector. The system provides alert routing and filtering: for example pressure readings from automated weather stations may conflict with a local terminal aerodrome forecast, resulting in(More)
This paper exhibits the first parallel sort algorithm for shared memory MIMD multiprocessors which has a theoretical and measured speedup near linear. The algorithm is based on a new asynchronous parallel merge which evenly partitions data to be merged between any number of processors. The merge of data sets @ and 63 on p processors has a time complexity of(More)
The Prism simulation system models the interaction of application, system and architectural structures for shared memory multiprocessors and distributed memory multicomputers. The simulation is achieved using two major components, a compiler and a library of processor and architecture modeling routines. The compiler processes application and system code(More)
The rationale that subtalar joint position, reflected by calcaneal alignment, determines foot morphology was used to formulate an approach to examination of the validity of three measures of "foot type": the Staheli Arch Index, the Chippaux-Smirak Index, and navicular height. Each measure was calculated in five positions, progressively inverting from a(More)
Children are commonly brought into clinic by parents anxious over ‘flat feet’. Whilst flat feet may represent a normal developmental process, the natural history of foot posture in children is incompletely understood. This fuels controversy concerning which foot postures necessitate clinical intervention. The persistence of this controversy may be due, at(More)
