title	Comparison between Genetic Optimization and Heuristic Methods for Prioritizing Infrastructure Rehabilitation Programs
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 175-182
summary	In recent years, infrastructure rehabilitation has been in the focus of attention in North America and around the world. A large percentage of existing infrastructure assets is deteriorating due to harsh environmental conditions, insufficient capacity, and age. Due to stringent budget limits, however, asset management systems become important to assess the life cycle performance of various assets, and accordingly prioritize the assets for rehabilitation purposes. While many asset management systems have been introduced in the literature, almost no studies have compared the effectiveness of their asset prioritization methods. This paper presents an extensive comparison between heuristic and optimization methods for prioritizing large-scale rehabilitation programs, under budget constraints. The paper first introduces different life cycle cost analysis (LCCA) formulations for three case studies obtained from the literature related to buildings, pavements, and bridges. Based on extensive experiments with the three case studies and on different network sizes, heuristic techniques proved its practicality for handling various network sizes. The performance of genetic optimization, on the other hand, was more efficient on small-scale networks but showed steep degradation in performance with large-scale problems. This research can be beneficial to municipalities and asset managers and can help them design efficient methods to sustain the safety and operability of the civil infrastructure, with least cost.

title	Interrogating the Relation between E-Mobility Recharging Network Design and Drivers' Charging Behaviour
doi	https://doi.org/10.52842/conf.ecaade.2014.1.213
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 213-224
summary	In this article we report on research into patterns of electric vehicle (EV) commuters' movement and behavior in a road network. The design of the charging network is a function of its size and the distribution of the charging points. It consists of several spatial design qualities, configuration attributes, travel demand, and users charging patterns. This study introduces the spatial configuration of an active e-mobility system through a case study. The article investigates the correlation between the design characteristics of EV recharging infrastructure and its usability. We need to explore the variations in individual charging behavior within the EV population to understand the movement patterns in the network. Using data of over 500 EV drivers charging their cars using Recharging facilities (RFs) over a three-year time, we clustered the EV population based on the charging patterns. Design configuration analysis is conducted using DepthMap; charging patterns are captured by the infrastructure service provider.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

title	On the Shores of Architecture

source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 853–862
summary	This paper explores the implications of complex geometry enabled by computational technology to architectural theory and practice. It reviews the different design paradigms engaged breaking the horizontality of the floor and ceiling or fusing them together. It argues that current advances in fluid dynamics simulations open a new frontier in the conception of the usable architectural surface, in which the architectural product is no longer a fixed object, but the interaction between a fluid, changing environment and built form. The paper presents a case study in which computational fluid dynamics are utilized to reconvert a disused breakwater into a ‘blue garden’. The morphology of the breakwater and its texture are calculated to produce the conditions amiable for supporting a varied marine ecosystem, and to shape the waves to generate aesthetically meaningful sensations. The essay discusses the technical and conceptual challenges of controlling the nonlinear behaviour of fluids. It then speculates on the theoretical ramifications of having the surface interact with exterior forces and the subject's imagination to produce an event enfolding in time.

title	Spatial Agglomerates
doi	https://doi.org/10.52842/conf.caadria.2014.585
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 585–594
summary	This paper reports on the computational modelling research investigating spatial organisations often associated with unplanned settlements. Such spatial agglomerates are composed of several co-located but autonomous units (agents) that share common facilities and infrastructure (e.g. circulation). Depending on the context, units in the agglomerate represent individual dwellings, apartments or abstract spatial geometry. The paper presents early prototype models that can be interpreted at various scale, and a computational model for generating organic settlement layouts. The originality of the research resides within a new multi-agent algorithm for creating spatial organisations. The agglomeration process benefits from two distinct generative design strategies – self-organisation and adaptive development strategy. While the self-organisation accounts for the emergence of the global structure in the agglomeration, the adaptive development strategy ensures that the basic environmental and spatial requirements of each individual unit are satisfied.

summary	This paper presents research into a technique using context-aware agent based branching L-systems to design explore an urban development scheme in an area of peripheral Mexico City. The design research demonstrates a viable approach to engaging design with specific agent driven objectives that negotiate across highly differentiated fields of data sets. These data sets are the driving force behind this technique, to generate highly differentiated infrastructure and urban networks that are simulated to be autonomous and emergent. The described system consists of simulated robotic autonomous agents that sample and negotiate across data from the site, and react to differences in order to deploy an irrigation network for a polluted and highly saline former lake-bed east of Mexico City.

title	Parasitic Ecologies - Algorithmic Space through Diffusion-Limited Aggregation of Truncated Octahedrons
doi	https://doi.org/10.52842/conf.ecaade.2014.2.539
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 2, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 539-546
summary	Parasitic architecture allows the creation of flexible structures that feed off existing infrastructure. Additionally, self-organised models that grow in response to environmental forces and adapt to their context introduce new ways for intervening in architectural design. This paper investigates the properties of self-organised parasitic structures that evolve by creating aggregation forms in the context of simulated structural environments. The growth process of the parasitic structures is inspired by the fungal colonies and is based on the rules of diffusion-limited aggregation (DLA) extended to support real-time force analysis and aggregation of space-filling geometry. The results of the simulations demonstrate that the developed diffusion-limited aggregation of truncated octahedrons is capable of providing self-sustained structures able to adapt in environments with different spatial limitations.
