Geometry-Driven Stock-Constrained Truss Design via Equilibrium-Based Structural Models
Corentin Jean Dominique Fivet, Tao Sun
This paper presents a geometry-driven approach to form-finding with reused stock elements. Our proposed workflow uses a K-mean algorithm to cluster stock elements and incorporate their geometrical values early in the form-finding process. A feedback loop i ...
Springer2024Learning to Remove Cuts in Integer Linear Programming
Volkan Cevher, Grigorios Chrysos, Efstratios Panteleimon Skoulakis
Cutting plane methods are a fundamental approach for solving integer linear programs (ILPs). In each iteration of such methods, additional linear constraints (cuts) are introduced to the constraint set with the aim of excluding the previous fractional opti ...
2024Safe Zeroth-Order Convex Optimization Using Quadratic Local Approximations
Giancarlo Ferrari Trecate, Maryam Kamgarpour, Yuning Jiang, Baiwei Guo
We address black-box convex optimization problems, where the objective and constraint functions are not explicitly known but can be sampled within the feasible set. The challenge is thus to generate a sequence of feasible points converging towards an optim ...
2023Estimation of Self-Exciting Point Processes from Time-Censored Data
Thomas Alois Weber, Philipp Schneider
Self-exciting point processes, widely used to model arrival phenomena in nature and society, are often difficult to identify. The estimation becomes even more challenging when arrivals are recorded only as bin counts on a finite partition of the observatio ...
2023Manning's Formula and the Strickler Scaling Derived from a Co-spectral Budget Model
Gabriele Manoli, Sara Bonetti, Gabriel George Katul
Manning's empirical formula in conjunction with Strickler's scaling is widely used to predict the bulk velocity (V) from the hydraulic radius (Rh), the roughness size (r), and the slope of the energy grade line (S) in uniform channel flows at high bulk Rey ...
2023Identifying invariant solutions of wall-bounded three-dimensional shear flows using robust adjoint-based variational techniques
Tobias Schneider, Omid Ashtari
Invariant solutions of the Navier-Stokes equations play an important role in the spatiotemporally chaotic dynamics of turbulent shear flows. Despite the significance of these solutions, their identification remains a computational challenge, rendering many ...
Cambridge2023An Inverse-Filter-Based Method to Locate Partial Discharge Sources in Power Transformers
Marcos Rubinstein, Hamidreza Karami
Partial discharge (PD) occurrence in power transformers can lead to irreparable damage to the power network. In this paper, the inverse filter (IF) method to localize PDs in power transformers is proposed. To the best of the authors’ knowledge, this is the ...
