Liang, X. (author)Advanced high strength steels (AHSS) have been widely employed in the automotive industry to meet the requirements of improving crash performance while reducing vehicle weight. The excellent performance of AHSS in strength and ductility comes from a dedicated design of alloy composition and microstructure. However, the addition of some alloying...doctoral thesis 2024

Bagirov, Aslan (author)Structural design for unconventional aircraft can be quite challenging and could undergo<br/>many iterations until a solution is found for all load-cases such as static sizing, stability and<br/>crashworthiness. Ultimately, all of the design aspect are integrated in the earliest design<br/>changes for which Topology Optimization (TO) could...master thesis 2024

Guichard, Etienne (author)Neural Cellular Automata (NCA) have recently been proposed as neuromorphic robot controllers. Despite their promising behavioural characteristics and small parameter counts, training NCA for control tasks has proven difficult and unstable. It is so tricky that curriculum-like multi-stage training programs must be used for simple control tasks....master thesis 2024

Bley, Eoinlee (author)Mechanical computing systems have historically faced challenges in efficiently integrating computation and memory functions, often leading to complex designs and limited scalability in applications ranging from micro-electromechanical systems (MEMS) to programmable matter. This study aims to address this issue by introducing a mechanical system...master thesis 2023

Puente Barajas, Daniel (author)This paper describes the process and evaluation methods by which we adapted a Reaction-Diffusion model and an order parameter to monitor its segregation state in a 2D Cellular Automaton model. The model simulates Turing pattern formations, whose behavior will be studied by an order parameter formulated for this project. This order parameter acts...bachelor thesis 2023

Tang, Jian (author), Kumar, Siddhant (author), De Lorenzis, Laura (author), Hosseini, Ehsan (author)We propose Neural Cellular Automata (NCA) to simulate the microstructure development during the solidification process in metals. Based on convolutional neural networks, NCA can learn essential solidification features, such as preferred growth direction and competitive grain growth, and are up to six orders of magnitude faster than the...journal article 2023

Liolis, Orestis (author), Mardiris, Vassilios A. (author), Karafyllidis, Ioannis G. (author), Cotofana, S.D. (author), Sirakoulis, Georgios Ch (author)Quantum-dot Cellular Automata (QCA) provide very high scale integration potential, very high switching frequency, and have extremely low power demands, which make the QCA technology quite attractive for the design and implementation of large-scale, high-performance nanoelectronic circuits. However, state-of-the-art QCA circuit designs were...journal article 2023

Traka, K. (author)The present thesis investigates recrystallization and related phenomena in interstitial free (IF) and low carbon (LC) microstructures. Emphasis is given mostly on the early stages of recrystallization, i.e. nucleation stage. The investigations are performed with experimental measurements and computer simulations. In all studies,...doctoral thesis 2022

Li, Bo (author), Wang, Yue (author), Wang, T. (author), He, Xiaoman (author), Kazak, Jan K. (author)With the advancement of urbanization, the stress on the green infrastructure around the urban agglomeration has intensified, which causes severe ecological problems. The uncertainty of urban growth makes it difficult to achieve effective protection only by setting protection red lines and other rigid measures. It is of practical significance to...journal article 2022

Aydin, N.Y. (author), Krishnan, S. (author), Yu, H. (author), Comes, M. (author)Cities are complex socio-technical systems (STSs) under tremendous stress due to climate change. To incorporate resilience into urban plans and move towards evidence-based long-term decision-making, we must unravel complex land-use dynamics and the effect of climate uncertainties on cities. Currently, land-use dynamics are explored through...conference paper 2022

YU, HONGXUAN (author)Urbanization makes cities more vulnerable in the face of climate change risks. Understanding urban growth under climate change can help planners optimize land allocation and development strategies that are resilient to the impacts of climate change. However, the complexity and uncertainty of climate change hinder the urban...master thesis 2021

Mariot, L. (author), Picek, S. (author), Jakobovic, Domagoj (author), Leporati, Alberto (author)Reversible Cellular Automata (RCA) are a particular kind of shift-invariant transformations characterized by dynamics composed only of disjoint cycles. They have many applications in the simulation of physical systems, cryptography, and reversible computing. In this work, we formulate the search of a specific class of RCA – namely, those...journal article 2021

Lu, Jenny (author)In this bachelor thesis we propose a spatial Markov Chain Cellular Automata<br/>model for the spread of the COVID-19 virus as well as two methods for parameter<br/>estimation. Network topologies are used to model the progression of the epidemic<br/>by considering each individual on a grid and using stochastic principles to determine the...bachelor thesis 2020

Dang, Y. (author)How a system of genetically identical biological cells organizes into spatially heterogeneous tissues is a central question in biology. Even when the molecular and genetic underpinnings of cell-cell interactions are known, how these lead to multicellular patterns is often poorly understood. Of particular interest are dynamic patterns such as...doctoral thesis 2020

Chen, J. (author)Cancer is known as one of the leading causes of death in the world with difficult<br/>diagnose at early stages, poor prognosis and high mortality. Animal-based<br/>experiments and clinical trials have always been the main approach for cancer<br/>research, albeit they may have limitations and ethical issues. Mathematicalmodeling<br/>as an...doctoral thesis 2020

Mariot, L. (author), Manzoni, Luca (author), Dennunzio, Alberto (author)We continue the study of asynchrony immunity in cellular automata (CA), which can be considered as a generalization of correlation immunity in the case of vectorial Boolean functions.

Dang, Y. (author), Grundel, D.A.J. (author), Youk, H.O. (author)Cells form spatial patterns by coordinating their gene expressions. How a group of mesoscopic numbers (hundreds to thousands) of cells, without pre-existing morphogen gradients and spatial organization, self-organizes spatial patterns remains poorly understood.
