Stepwells were mainly designed for religious, water conservation, and social purposes. This paper indicates those aspects in exploring the complex arrangement of the repetitive self-similar stair units in Chand Baori. The geometric quality of self-similar repetition resulting in a complex outcome can be systematically described by fractal geometry. Hence, this paper has adopted a fractal-based computational approach to model the Chand Baori stepwell, including a new stepwell design followed by the Sierpinski triangle, a canonical example of mathematical fractals. The fractal dimension method has been applied at the end to analyze the visual complexity of Chand Baori.

In this setting with multiple talkers, speech distraction can be a significant cause of dissatisfaction and loss of productivity. Ceiling treatment in open plan work environments can provide an important way of ameliorating distraction from unattended speech, and rather than absorbing the sound at the ceiling, this paper examines the possibility of reflecting sound back to the source. Computational design and digital fabrication are integrated in this research for a site-specific deployment of the ceiling treatment and physical testing of prototypes in an acoustics laboratory. The contemporary possibilities that open up with new technologies to understand and resurrect faceted geometries and potentially vary historical precedents via new manufacturing techniques are demonstrated in these novel acoustic reflective ceilings that reflect sound back to their original source.

This has tended to distract from the concomitant existence of tree-like splits within Berber, first noted a century ago but clarified more recently. As a result, the study of intra-Berber diffusion has been largely neglected, even though the existence of dialect continua implies diffusion. This article lays out the principal models proposed for the sub-classification of Berber, a field which has advanced significantly in recent decades, along with their historical implications. It then presents two very different case studies the Blida Atlas (Algeria), and Zenaga (Mauritania)demonstrating that intra-Berber contact can sometimes be detected, even in quite basic vocabulary, and that the results fit well with the history implied by extra-linguistic data. Avenues for further research are suggested.

This paper presents ongoing research that involves three scales of operation; a global geometry for multi-skin cellular mesh densities; localised skin-porosity detailing, and material structural optimisation. Centering on a chair as a test case scenario, the research explores the affordances of a serialised, multi-material 3D printing process in the context of digital instruction, customisation, and material efficiency. The paper discusses two case studies with consecutive optimisation, and outlines the benefits and limitations of 3D printing for structural optimisation and multi-material grading in the additive process.

This demo presents an approach to spatial design that implements techniques of interactive (immersive, spatial) art, to produce architectural 'spaces' that are expressed through the medium of interaction. 'Trivet Fields' is one example from a series of soundspace works that introduce interactive art computing to architectural practice, providing a new platform for cross-disciplinary explorations in esthetics of space.

Randomness is introduced as degrees of variations in code, both supported by quasi-predictable variations in a computational process, and the select changes through multiple variables in precise robotic fabrication that extend the spectrum for manufacturing diversity in micro-geometries that can change the acoustic response of space. Through physical acoustic testing of scale model 1:10 prototypes in a scale model reverberant box, and consecutive remodelling of sound discs based on root mean square and depth comparison, a tendency for acoustic behaviours both for scattering and absorption could be demonstrated that relates low spatial frequency magnitude of surface modulation closely to scattering coefficient in a limited case study of six samples. As a result, the study presents a mathematical model that links form and material for sound scattering.

The control over geometry and structural performance of arches, domes and vaults continues to be exemplary and structural integrity is analysed through analogue and virtual simulation methods. With the advancement of computational tools and software development, finite and discrete element modeling have become efficient practices for analysing aspects for economy, tolerances and safety of stone masonry structures. This paper compares methods of structural simulation and analysis of an arch based on an interlocking wave joint assembly. As an extension of standard planar brick or stone modules, two specific geometry variations of catenary and sinusoidal curvature are investigated and simulated in a comparison of physical compression tests and finite element analysis methods. This is in order to test the stress performance and resilience provided by three-dimensional joints respectively through their capacity to resist vertical compression, as well as torsion and shear forces. The research reports on the threshold for maximum sinusoidal curvature evidenced by structural failure in physical modelling methods and finite element analysis.

This will reduce energy and material leakage from the economy and create new opportunities for innovation in materials. Mycomaterials provide an opportunity to transform ligno-cellulosic matter, such as waste cardboard and sawdust, into useful materials. This is achieved by using a fungus to bind together these substrates into useful forms. This paper explores how computational design parameters can be informed from the mycelia growth process. We created several prototype forms that show behaviour of myco-materials through the growing and drying process. These show how inclusion of cardboard substructures may improve the performance of the resulting material by increasing its stability during the drying process. We also demonstrate limits to the size of myco-materials through computational design. Myco-materials will likely be part of a sustainable post-carbon economy, by bringing new value to waste material, and this paper shows how computational design can be informed by mycelial growth.
