Recent real-world deployments of Stackelberg security games make it critical that we address human adversaries' bounded rationality in computing optimal strategies. To that end, this paper provides three key contributions: (i) new efficient algorithms for computing optimal strategic solutions using Prospect Theory and Quantal Response Equilibrium; (ii) the(More)
The feasibility of replacing oxygen with a synthetic electron acceptor in microbial catabolism was investigated as a rapid method for the determination of biochemical oxygen demand (BOD). Microorganisms known for their broad range organic substrate utilisation were investigated. It was shown that Trichosporon cutaneum, Pseudomonas putida and Bacillus(More)
Ferricyanide-mediated (FM) microbial reactions were used for the rapid determination of the biochemical oxygen demand (BOD) of a range of synthetic and real wastewater samples. Four single-species microbial seeds and a synthetically prepared microbial consortium were compared. In all cases, the microbial consortium exhibited a greater extent and rate of(More)
Activated sludge was successfully incorporated as the biocatalyst in the fast, ferricyanide-mediated biochemical oxygen demand (FM-BOD) bioassay. Sludge preparation procedures were optimized for three potential biocatalysts; aeration basin mixed liquor, aerobic digester sludge and return activated sludge. Following a 24h starving period, the return(More)
This study examined the utility of the TELE, a telephone assessment for dementia, in a sample of 269 individuals that was not selected on the basis of previous dementia diagnosis. Thus, the conditions of the study reflect the actual situation in which a screening instrument might be employed. Scores on TELE were compared to dementia diagnoses. Using the(More)
Game-theoretic approaches have been proposed for addressing the complex problem of assigning limited security resources to protect a critical set of targets. However, many of the standard assumptions fail to address human adversaries who security forces will likely face. To address this challenge, previous research has attempted to integrate models of human(More)
Stackelberg games have garnered significant attention in recent years given their deployment for real world security. Most of these systems, such as ARMOR, IRIS and GUARDS have adopted the standard game-theoretical assumption that adversaries are perfectly rational, which is standard in the game theory literature. This assumption may not hold in real-world(More)
It becomes critical to address human adversaries' bounded rationality in security games as the real-world deployment of such games spreads. To that end, the key contributions of this paper include: (i) new efficient algorithms for computing optimal strategic solutions using Prospect Theory and Quantal Response Equilibrium; (ii) the most comprehensive(More)
Theoretical and practical insights into the design and development of immobilised enzyme inhibition biosensors are reported. A general mathematical expression relating the percent of enzyme inhibition (i.e. the analytical signal) to both the inhibitor concentration and the incubation time is presented. The relevant physical, chemical and biochemical(More)
