This report describes the results of research to develop and apply a comprehensive model to consider the influence of the mix of vehicle types on the total safety of the light passenger vehicle fleet in Australia. Key inputs to the model are estimates of the crashworthiness and aggressivity of light passenger vehicles in the key crash types representing the majority of crashes in which these ve...

Large complex systems, such as power plants, ships and aircraft, are composed of multiple systems, subsystems and components. When they are considered as embedded in operating systems such as a fleet, mission readiness and maintenance management issues are raised. PHM (Prognostics and Health Management) plays a key role in controlling the performance level of such systems, at least on the basis...

Work-related vehicle crashes are a common cause of occupational injury. Yet, there are few studies that investigate management practices used for light vehicle fleets (i.e. vehicles less than 4.5 tonnes). One of the impediments to obtaining and sharing information on effective fleet safety management is the lack of an evidence-based, standardised measurement tool. This article describes the ini...

The FLEET computer [1] is a new architecture designed from the ground up with parallelism in mind, providing the programmer with direct control over data movement and concurrency. Since FLEET is a completely new architecture, programming for it can be quite challenging. The machine is inherently parallel, so sequential programming techniques do not directly translate to it. The MIPS to FLEET tr...

Aging aircraft can be effectively managed by a combination of deterministic and probabilistic metrics. The deterministic metric provides a damage index for each aircraft relative to the full-scale test. This indexing method based on crack initiation or crack growth, may not be singly sufficient to support fleet management decisions at a time when the fleet is aging. To ensure safety of fleet, a...

With the increasing reliance on space systems for communications, the number of multi-satellite, multimission operators, in both the government and commercial sectors, is also increasing. To prevent the operations and maintenance costs from increasing linearly, or worse, with the number of satellites, operators are attempting to consolidate operations and maintenance across the satellite fleet....

As one of the most complex steps in fabric production, sizing plays a very important role in the weaving process. The primary purpose of the sizing process is to obtain the warp threads that can successfully be woven without major damages which occur during the yarn passage through sliding metal parts of the weaving machine (Lord, 2003). It applies to the improvement of physical and mechanical ...

Early estimation of the size of a software product is extremely important. In this paper we analyze two software packages developed by a CMM level 3 software firm. We study if any property of analysis objects can be used to infer the size of the final code in an object-oriented environment. In both cases we find the number of methods well correlated with software size, in the sense that the cor...

A review of past, current, and emerging electric vehicle (EV) propulsion system technologies their integration is the focus this paper, namely, matching motor (EM) transmission (TRM) to meet basic requirements performance targets. The fundaments EM TRM from a tractive effort dynamics perspective are provided as an introductory context available or near-production products OEM Tier 1 suppliers. ...

Looking at the distribution of the costs of IT, the largest part of the budget is allocated to maintenance and enhancement projects. New development comprises between 30 to 50% of IT costs. Functional size measurement methods are mostly used for new development only. With some extensions to common size measurement methods like Function Point Analysis and COSMIC Full Function Point one can tackl...
