In this paper, we develop a numerical resolution of the space-time fractional advection-dispersion equation. We utilize spectral-collocation method combining with a product integration technique in order to discretize the terms involving spatial fractional order derivatives that leads to a simple evaluation of the related terms. By using Bernstein polynomial basis, the problem is transformed in...

BACKGROUND Previous studies have suggested that informatics tools, such as automated alert and decision support systems, may increase the efficiency and quality of infection control surveillance. However, little is known about the cost-effectiveness of these tools. METHODS We focus on 2 types of economic analyses that have utility in assessing infection control interventions (cost-effectivene...

User evaluation in the domain of Music Information Retrieval (MIR) has been very scarce, while algorithms and systems in MIR have been improving rapidly. With the maturity of system-centered evaluation in MIR, time is ripe for MIR evaluation to involve users. In this study, we compare user-centered measures to a system effectiveness measure on the task of retrieving similar songs. To collect us...

Cost-effectiveness analysis (CEA), as a system of allocative efficiency for global health programs, is an influential criterion for resource allocation in the context of diplomacy and inherent foreign policy decisions therein. This is because such programs have diplomatic benefits and costs that can be uploaded from the recipient and affect the broader foreign policy interests of the donor and ...
