The Cognitive Shadow is a prototype tool intended to support decision making by autonomously modeling human operators’ response pattern and providing online notifications to the operators about the decision they are expected to make in new situations. Since the system can be configured either in a reactive “shadowing” or a proactive “recommendation” mode, this study aimed to determine its most effective mode in terms of human and model accuracy, workload, and trust. Subjects participated in an aircraft threat evaluation simulation without decision support or while using either mode of the Cognitive Shadow. Whereas the recommendation mode had no advantage over the control condition, the shadowing mode led to higher human and model accuracy. These benefits were maintained even when the tool was unexpectedly removed. Neither mode influenced workload, and the initial lower trust rating in the shadowing mode faded quickly, making it the best overall configuration for the cognitive assistant.

Structure Properties

AbstractMalformed data-structures can lead to runtime errors such as arbitrary memory access or corruption. Despite this, reasoning over data-structure properties for low-level heap manipulating programs remains challenging. In this paper we present a constraint-based program analysis that checks data-structure integrity, w.r.t. given target data-structure properties, as the heap is manipulated by the program. Our approach is to automatically generate a solver for properties using the type definitions from the target program. The generated solver is implemented using a Constraint Handling Rules (CHR) extension of built-in heap, integer and equality solvers. A key property of our program analysis is that the target data-structure properties are shape neutral, i.e., the analysis does not check for properties relating to a given data-structure graph shape, such as doubly-linked-lists versus trees. Nevertheless, the analysis can detect errors in a wide range of data-structure manipulating programs, including those that use lists, trees, DAGs, graphs, etc. We present an implementation that uses the Satisfiability Modulo Constraint Handling Rules (SMCHR) system. Experimental results show that our approach works well for real-world C programs.

Lung Airways

Fine to ultrafine materials, such as spherical particles and fibers with their diverse applications ranging from cosmetics, cleaners and composites to nanomedicine are increasingly ubiquitous in the air we breathe. For example, the unique lung deposition patterns of nanoparticles and their ease-of-migration into the blood stream may cause severe health problems, as discussed by Oberdoerster et al. (2005). In contrast, multifunctional nanoparticles as well as micron fibers are also being used as drug carriers for cancer treatment (Zhang et al., 2011). While the transport and deposition of spherical nanoparticles has been analyzed (Kleinstreuer and Zhang, 2010; among others), the fate of ellipsoidal particles in subject-specific lung airways has hardly been addressed. In this study, the Euler-Lagrange fluid-particle modeling approach (i.e., the Discrete Phase Method solver) has been employed in Fluent 13.0 (ANSYS, Canonsburg, PA). User-supplied C-programs have been added to simulate ellipsoidal fibers transport and orientation effects. The computer simulation model has been validated for fiber transport and deposition in a circular tube (Tian et al., 2012). Additionally, transitional airflow patterns were analyzed and local deposition efficiencies compared for spherical particles and fibers in a realistic human respiratory system. The capability of ellipsoidal fibers migrating into deeper lung regions was indicated and fiber deposition “hot spots” were discussed. The numerical results expand the basic understanding of the dynamics of non-spherical particles in realistic shear flows, and can be used to investigate the fate of inhaled toxic or therapeutic materials.
