Explaining the socio-economic output of urban regions with a model combining urban scaling and polycentricity
(2024)Urban Scaling: Allometry in Urban Studies and Spatial ScienceUrban scaling theory and polycentric urban development are two well-known concepts that draw parallels between configurations and socio-economic conditions of urban regions. Both concepts, however, have some drawbacks, which could potentially be alleviated by combining them in a new model. In this study, income in urban regions in Switzerland is explained by combining the hierarchy of a region’s commuter network (i.e. indicator for ...Book Chapter -
Smart rebar progress monitoring using 3D point cloud model
(2024)Expert Systems with ApplicationsCurrent rebar inspection practices in construction projects are manual in nature; hence, they are time-consuming. Rebar drawings are technical; therefore, the accuracy of inspection outcomes depends on the inspector's (supervisor or engineer) experience. In contrast, with the emergence of the fourth industrial revolution, the construction industry has also adopted a few technological solutions for rebar progress monitoring. However, most ...Journal Article -
Ensemble of surrogates in black-box-type engineering optimization: Recent advances and applications
(2024)Expert Systems with ApplicationsDue to its high efficiency, surrogate models have been extensively used in black -box -type engineering optimization problems. However, due to the nature of black -box functions, it is difficult to decide which surrogate model is the best for a given problem. In addition, it is difficult to accurately estimate the prediction accuracy of a surrogate on an expensive black -box function in advance. Because we cannot use many real expensive ...Review Article -
Cascade: CPU Fuzzing via Intricate Program Generation
(2024)Generating interesting test cases for CPU fuzzing is akin to generating programs that exercise unusual states inside the CPU. The performance of CPU fuzzing is heavily influenced by the quality of these programs and by the overhead of bug detection. Our analysis of existing state-of-the-art CPU fuzzers shows that they generate programs that are either overly simple or execute a small fraction of their instructions due to invalid control ...Conference Paper -
Morphologically reconfigurable magnetic micropillar arrays using acoustic streaming for particle capture and droplet manipulation
(2024)Sensors and Actuators B: ChemicalThe accurate and efficient manipulation of particles and droplets is crucial for the fields of disease diagnosis, target drug delivery, and sample purification, specific microstructure-based particle and droplet manipulation have been widely utilized in bioassays. However, current techniques are mainly based on the fixed microstructures, which is extremely difficult to achieve dynamic modulation by adjusting microstructure morphology and ...Journal Article -

Phase-field simulation and machine learning of low-field magneto-elastocaloric effect in a multiferroic composite
(2024)International Journal of Mechanical SciencesAchieving appreciable elastocaloric effect under low external field is critical for solid-state cooling technology. Here, a non-isothermal Phase-Field Model (PFM) coupling martensitic transformation with mechanics, heat transfer and magnetostrictive behavior is proposed to simulate Magneto-elastoCaloric Effect (M-eCE) that is induced by magnetic field in a multiferroic composite (e.g., Magnetostrictive-Shape Memory Alloys (MEA-SMA) ...Journal Article -
Reliability analysis of arbitrary systems based on active learning and global sensitivity analysis
(2024)Reliability Engineering and System SafetySystem reliability analysis aims at computing the probability of failure of an engineering system given a set of uncertain inputs and limit state functions. Active-learning solution schemes have been shown to be a viable tool but as of yet they are not as efficient as in the context of component reliability analysis. This is due to some peculiarities of system problems, such as the presence of multiple failure modes and their uneven ...Journal Article -
Augmenting materials passports to support disassembly planning based on building information modelling standards
(2024)Journal of Building EngineeringSelective disassembly planning and materials passports are precursor technologies to support the retrieval of reusable building components efficiently. Selective disassembly relies on information about the recovery capacity of the components, while materials passports can be used to keep track of the disassembly information along the component's life cycles. However, the required information for selective disassembly is not represented ...Journal Article -
Computational Design of 2D Lattice Structures Based on Crystallographic Symmetries
(2024)Journal of Mechanical DesignThe design representations of lattice structures are fundamental to the development of computational design approaches. Current applications of lattice structures are characterized by ever-growing demand on computational resources to solve difficult optimization problems or generate large datasets, opting for the development of efficient design representations which offer a high range of possible design variants, while at the same time ...Journal Article
