Hospitals are continually struggling to cater for the increasing demand for inpatient services. This is due to increased population, aging, and the rising incidence of chronic diseases associated with modern life. The high demand for hospital services leads to unpredictable bed availability, longer waiting period for acute admission, difficulties in keeping… (More)
Cache access latency and efficient usage of on-chip capacity are critical factors that affect the performance of the chip multiprocessor (CMP) architecture. In this paper, we propose a SPS2 cache architecture and cache coherence protocol for snooping-based CMP, in which each processor has both private and shared L2 cache to balance latency and capacity. Our… (More)
Autonomous moving objects (AMOs), such as automated guided vehicles (AGVs) and autonomous robots, have widely been used in the industry for decades. In an intelligent transport system with a great number of AMOs involved, it is important to eliminate potential congestion and deadlocks among AMOs to maintain a well-organized traffic flow. In this paper, we… (More)
Many organizations have to outsource some of their data mining tasks due to inadequate in-house IT expertise. During this process, the organizations lose full security control of their source data which may lead to the exposure of their business privacy. In this paper, we first present different application scenarios of outsourcing computing tasks of data… (More)
It is a well-known problem that Australian public hospitals are struggling to meet the increasing inpatient care demand, which often results to patient flow congestion and poor health care outcomes. Health care management practitioners and researchers have been trying to improve overall flow of patients with various modelling and data analysis approaches.… (More)
The establishment of an existing practice scenario was an essential component in providing a basis for further research in the area of COTS software acquisition within the organisation. This report details the identification of means of describing the existing practice of software acquisition within an organisation and identification of models that could be… (More)
Business process modeling can be used as an effective tool to understand requirements of software acquisition. This paper examines the current literature on the practices and their associated benefits and challenges in making software acquisition decisions with business process modeling, and demonstrates the need for further research in this area.
