Pinto, Martino (author)Particle Tracking Velocimetry (PTV) is an effective and non-intrusive flow measurement technique that is able to provide quantitative information of the full velocity field at a certain instant in time, by tracking each particle individually with high-speed cameras. This permits to have a very high precision in measuring the flow evolutions. The...master thesis 2024

Önen, Çağan (author), Pandharipande, Ashish (author), Joseph, G. (author), Myers, N.J. (author)Occupancy grid maps provide information about obstacles and available free space in the environment and are crucial in automotive driving applications. An occupancy map is constructed using point cloud data from sensor modalities like LiDAR and radar used for automotive perception. In this paper, we formulate the problem of estimating the...journal article 2024

Tallapragada, Bharadwaj (author)A popular class of methods for solving Fluid-Structure Interactions (FSI) problems computationally are the moving mesh deformation methods. These methods generally involve deforming the fluid domain so that it conforms to the structure as it undergoes changes. An efficient and robust moving mesh technique involves interpolation of displacements...master thesis 2023

Klees, R. (author), Slobbe, D.C. (author)This paper investigates the full variance–covariance (VC) matrix of two high-resolution regional quasi-geoid models, utilizing a spherical radial basis function parameterization. Model parameters were estimated using weighted least-squares techniques and variance component estimation (VCE) for data weighting. The first model, known as the ...journal article 2023

Andrade Castanheira, Francisco (author)The optimization of interplanetary, low-thrust trajectories is a computationally expensive aspect of preliminary mission design. To reduce the computational burden associated with it, surrogate models can be used as cheap approximations of the original fitness function. Training the surrogate models in a fully online manner can be done to...master thesis 2022

Chiang, Y.-C. (author)Shell structures carry loads with their thin yet curved shapes. Being thin means shells require little material, which is desirable for minimizing embodied carbon footprints. However, the feature of being curved implies shells require immense effort to design and fabricate. To address the challenges, this dissertation consists of three parts:...doctoral thesis 2022

(author), Daffner, Thomas (author), Triller, Falk (author), Kacimov, Anvar (author)Horizontal wells play an often overlooked role in hydrogeology and aquifer remediation but can be an interesting option for many applications. This study reviews the constructional and hydraulic aspects that distinguish them from vertical wells. Flow patterns towards them are much more complicated than those for vertical wells, which makes their...journal article 2022

Chiang, Y.-C. (author), Borgart, A. (author)The equilibrium of a membrane shell is governed by Pucher's equation that is described in terms of the relations among the external load, the shape of the shell, and the Airy stress function. Most of the existing funicular form-finding algorithms take a discretized stress network as the input and find the shape. When the resulting shape does...journal article 2022
