(author)Numerous studies have demonstrated the viability of lightweight Fe-Mn-Al-C steels for exhibiting an improved balance of high strength and high ductility in automotive applications. However, their high-cycle fatigue behaviour has been scarcely studied. This work examines the effect of κ-carbides formed during the aging treatment on the high...journal article 2024

Dutta, Debasish (author), Afzal, Mohammad Saud (author), Alhaddad, S.M.S. (author)This study utilizes three-dimensional simulations to investigate scour in combined wave–current flows around rectangular piles with various aspect ratios. The simulation model solves the Reynolds-averaged Navier–Stokes (RANS) equations using the k–ω turbulence model, and couples the Exner equation to compute bed elevation changes.

Dutta, S. (author), Bieling, T.J. (author), Verbiest, G.J. (author)Fluid flow processes such as drainage and evaporation in porous media are crucial in geological and biological systems. The motion of the displacement front of a moving fluid through multi-phase interfaces is often associated with abrupt mechanical energy release, detectable as acoustic emissions (AEs). The exact origin of these pulses and...journal article 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.

Banis, Alexandros (author), Gomez, Andrea (author), Dutta, Aniruddha (author), Sabirov, Ilchat (author), Petrov, R.H. (author)The strengthening via precipitation of nano-sized κ-carbides leads to exceptional strength-ductility balance in low-density steels. During aging, such nanocarbides form through spinodal decomposition by fluctuations in the aluminum and carbon content in the austenite, followed by short-range ordering. At lower aging temperatures and short...journal article 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

Dutta, S. (author), Chen, Zhiyi (author), Kaiser, Elias (author), Malcolm Matamoros, Priscilla (author), Steeneken, P.G. (author), Verbiest, G.J. (author)Although it is well known that plants emit acoustic pulses under drought stress, the exact origin of the waveform of these ultrasound pulses has remained elusive. Here, we present evidence for a correlation between the characteristics of the waveform of these pulses and the dimensions of xylem conduits in plants. Using a model that relates the...journal article 2022

Plants need water for many vital functions including nutrient uptake, growth and leaf cooling. The regulation of plant water transport by stomata in the leaves leads to the loss of 97% of the water that is taken up via their roots, to the atmosphere. Measuring plant...book chapter 2022
