Management of water resources often involves significant negotiation with regard to complex social, economic and environmental trade-offs likely to result from changes in policy or access. In NSW, changes to water allocations and access, through the design and implementation of Water Sharing Plans, involved negotiation between stakeholders representing many different interests and concerns. A k...

Mathematical optimisation is used to integrate and economically evaluate wastewater reuse, desalination and other water management options for water supply in Ensenada, Baja California Mexico with future levels of population and water demand. The optimisation model (CALVIN) is used to explore and integrate water management alternatives such as water markets, reuse and seawater desalination, wit...

Communication constraints dictated by hardware often require a multi-robot system to make decisions and take actions locally. Unfortunately, local knowledge may impose limits that ultimately impede global optimality in a decentralized optimization problem. This paper enhances a recent anytime optimal assignment method based on a task-swap mechanism, redesigning the algorithm to address task all...

Extracting binary strings from real-valued biometric templates is a fundamental step in many biometric template protection systems, such as fuzzy commitment, fuzzy extractor, secure sketch, and helper data systems. Previous work has been focusing on the design of optimal quantization and coding for each single feature component, yet the binary string—concatenation of all coded feature component...

Enterprise-wide distributed computing systems are inherently stochastic and the performance management of distributed applications running on the top of DCS is a complex and computationally hard task. In this paper, we define the enterprise distributed application and provide queueing analysis on the relationship between the application level performance parameters and the network and computer ...

The resource allocation in multiuser Orthogonal Frequency Division Multiplexing (OFDM) systems is addressed, which aims to maximize the user-perceived quality of services instead of the conventional objective metrics. By introducing the previous application-centric Mean Opinion Score (MOS) assessment model, the problem is formulated as a bounded optimization problem, which is non-concave and di...

The in-memory cache system is a performance-critical layer in today’s web server architecture. Memcached is one of the most effective, representative, and prevalent among such systems. An important problem is memory allocation. The default design does not make the best use of the memory. It fails to adapt when the demand changes, a problem known as slab calcification. This paper introduces loca...
