van de Ven, Daan (author), Hofland, Bas (author), van Kester, Dennis (author), Smith, Greg (author), Antonini, A. (author)When constructing land reclamations, often sand is placed on top of the coarse rock of the bund surrounding the reclamation. The use of a geometrically open filter between the interface of sand and rock could be cost effective. It is expected that even a geometrically open filter with sand on top of gravel might be stable due to the arching...conference paper 2023

Nannini, Luca (author), Balayn, A.M.A. (author), Smith, Adam Leon (author)Public attention towards explainability of artificial intelligence (AI) systems has been rising in recent years to offer methodologies for human oversight. This has translated into the proliferation of research outputs, such as from Explainable AI, to enhance transparency and control for system debugging and monitoring, and intelligibility of...conference paper 2023

Dutta, Shamak (author), Wilde, N. (author), Tokekar, Pratap (author), Smith, Stephen L. (author)We study the sample placement and shortest tour problem for robots tasked with mapping environmental phenomena modeled as stationary random fields. The objective is to minimize the resources used (samples or tour length) while guaranteeing estimation accuracy. We give approximation algorithms for both problems in convex environments. These...conference paper 2023

Dutta, Shamak (author), Wilde, N. (author), Smith, Stephen L. (author)We consider a general form of the sensor scheduling problem for state estimation of linear dynamical systems, which involves selecting sensors that minimize the trace of the Kalman filter error covariance (weighted by a positive semidefinite matrix) subject to polyhedral constraints. This general form captures several well-studied problems...conference paper 2023

Botros, Alexander (author), Sadeghi, Armin (author), Wilde, N. (author), Alonso-Mora, J. (author), Smith, Stephen L. (author)Many problems in robotics seek to simultaneously optimize several competing objectives under constraints. A conventional approach to solving such multi-objective optimization problems is to create a single cost function comprised of the weighted sum of the individual objectives. Solutions to this scalarized optimization problem are Pareto...conference paper 2023

Noom, J. (author), Soloviev, O.A. (author), Smith, C.S. (author), Nguyen, Hieu Thao (author), Verhaegen, M.H.G. (author)We demonstrate a novel closed-loop input design technique on the detection of particles in an imaging system such as a fluorescence microscope. The probability of misdiagnosis is minimized while constraining the input energy such that for instance phototoxicity is reduced. The key novelty of the closed-loop design is that each next input is...conference paper 2022

Noom, J. (author), Soloviev, O.A. (author), Smith, C.S. (author), Verhaegen, M.H.G. (author)Some applications require high level of image-based classification certainty while keeping the total illumination energy as low as possible. Examples are minimally invasive visual inspection in Industry 4.0, and medical imaging systems such as computed tomography, in which the radiation dose should be kept “as low as is reasonably achievable”...conference paper 2022

Dutta, Shamak (author), Wilde, N. (author), Smith, Stephen L. (author)In this paper, we consider a subset selection problem in a spatial field where we seek to find a set of k locations whose observations provide the best estimate of the field value at a finite set of prediction locations. The measurements can be taken at any location in the continuous field, and the covariance between the field values at...conference paper 2022

Dutta, Shamak (author), Wilde, N. (author), Smith, Stephen L. (author)We present a new mixed integer formulation for the discrete informative path planning problem in random fields. The objective is to compute a budget constrained path while collecting measurements whose linear estimate results in minimum error over a finite set of prediction locations. The problem is known to be NP-hard. However, we strive to...conference paper 2022

Cai, Yifan (author), Dahiya, Abhinav (author), Wilde, N. (author), Smith, Stephen L. (author)In this paper, we consider the problem of allocating human operator assistance in a system with multiple autonomous robots. Each robot is required to complete independent missions, each defined as a sequence of tasks. While executing a task, a robot can either operate autonomously or be teleoperated by the human operator to complete the task at...conference paper 2022

We use tilted light-sheet microscopy to achieve optical sectioning in localization microscopy, enabling thick sample observation and low background photon count images. A deformable mirror was incorporated to generate a tetrapod point...conference paper 2021

Beckman, W. (author), Siao, D. (author), Smith, C. (author), Corns, K. (author)The use of safety culture surveys to determine constituent perception of an organization’s efforts toward safety is widely accepted. However, the use of such surveys to compare disciplines within a collegiate aviation department has infrequently been employed. Students enrolled in flight, maintenance, and UAS programs participated in a safety...conference paper 2019

Holbrook, J. (author), Prinzel III, L.J. (author), Stewart, M.J. (author), Smith, B.E. (author), Matthews, B.L. (author)Safety in aviation has been historically defined in terms of the occurrence of accidents or recognized risks; that is, safety is typically defined in terms of things that go wrong. An alternative and complementary approach is to focus on what goes right, and identify how to make that happen again. Focusing on the rare cases of failures...conference paper 2019
