Critical behavior of Ising spin systems: Phase transition, metastability and ergodicity

Physical phenomena commonly observed in nature such as phase transitions, critical phenomena and metastability when studied froma mathematical point of view may give arise to a rich variety of behavior whose study becomes interesting in itself. In Chapter 1 we illustrate the phase transition phenomenon at low temperatures for one-dimensional...

Cellular automata based S-boxes

Cellular Automata (CA) represent an interesting approach to design Substitution<br/>Boxes (S-boxes) having good cryptographic properties and low implementation costs. From the cryptographic perspective, up to now there have been only ad-hoc studies about specific kinds of CA, the best known example being the χ nonlinear transformation used in...

Modeling cell–cell communication for immune systems across space and time

Communicating is crucial for cells to coordinate their behaviors. Immunological processes, involving diverse cytokines and cell types, are ideal for developing frameworks for modeling coordinated behaviors of cells. Here, we review recent studies that combine modeling and experiments to reveal how immune systems use autocrine, paracrine, and...

The effects of climate change on coastal management in the Hondsbossche Dunes: Analysis and modeling of aeolian sediment transport and dune growth

In 2003, it was established that the sea dike between Petten and Camperduin was insufficiently safe.<br/>To ensure the safety of the hinterland against flooding, this part of the Dutch sea defence system needed to be strengthened.<br/>During the design process, the most favourable variant was to construct a dune and beach system in front of the...

Lightweight and Side-channel Secure 4 × 4 S-Boxes from Cellular Automata Rules

This work focuses on side-channel resilient design strategies for symmetrickey cryptographic primitives targeting lightweight applications. In light of NIST’s lightweight cryptography project, design choices for block ciphers must consider not only security against traditional cryptanalysis, but also side-channel security, while adhering to low...

Informed Transformations

Informed Transformations looks into revamp of Marconi Towers in Rotterdam in light of Information Age, as Tofflers describe it. Information processing though IT resonates with todays rhizomatic distribution of power, insfluence, data and space as well. Everchanging socio-economic context can be treated by a meta-design that binds input of...

Kinetics of austenite to ferrite transformation and microstructure modelling in steels

The mechanical properties of steel are influenced by its microstructure, which is obtained as a result of processing conditions. It is, thus, important to study the effect of these conditions on the microstructure. A three dimensional microstructure model, based on a cellular automata (CA) model, was previously developed. The model is capable of...

Geological Modelling with GOAL and Cellular Automata

The hydrocarbon reservoirs that are relatively easy to find and produce are becoming increasingly more scarce. The geographical location and the internal complexity of the majority of the reservoirs that are brought into production necessitate extensive research of all the reservoir characteristics. One element in the array of research tools is...

Generating High Density Residential Housing Apartments in the edge of City Den Haag Vliet/A4 Zone

The intervention is located on the 30000 m2 land bordered to the east side of the Vliet River and serves as a transaction to the future residential development in Prince Clausplein. This area surrounded from three sides by existing residential units connecting to the A4 highway and commercial zone in the east side. A Main public space structures...

Multigrid Implementation of Cellular Automata for Topology Optimisation of Continuum Structures with Design Dependent loads

Topology optimisation of continuum structures has become mature enough to be often applied in industry and continues to attract the attention of researchers and software companies in various engineering fields. Traditionally, most available algorithms for solving topology optimisation problems are based on the global solution approach and...

Optimal design of variable-stiffness fiber-reinforced composites using cellular automata

Growing number of applications of composites materials in aerospace and naval structures along with advancements in manufacturing technologies demand continuous innovations in design of composite structures. In the traditional design of composite laminates, fiber orientation angles are constant for each layer and are usually limited to 0, 90,...
