Architectural Hybrid (Physical-Digital) Prototyping In Design Processes With Digital Twin Technologies, Gulbahar Emir Isik, Henri Achten

Architecture and Planning Journal (APJ)

A digital twin is a simultaneous digital reflection of object processes and states. Digital twins are usually made of objects that exist in reality or which are very near completion in a design and production process. In our research, we investigate the potential of digital twin technology for early design. Key to the early application of digital twin in design is the role of information and simulation. Since design information is valuable for predicting the future of design, we assume that design will begin to change as digital twin technologies become more and more adaptable, as designers simultaneously have digital …

Gestural Design - Hand Tracking For Digital Drawing, Jordan A. Kanter, Kamil Quinteros

Architecture and Planning Journal (APJ)

Computational design is increasingly interested in the active feedback between the user/designer and the digital space. Often, our initial instinct as designers comes from a gesture, a movement of the hands that gets translated into sketches and 3D models via the tools available to us. While the physical realm allows for muscle memory, tactile feedback, and creative output via movement, digital design often negates the body of the designer as it sequesters us into a screen-mouse-hand relationship. Moreover, current CAD software tools often reinforce this standardization, further limiting the potential of physical bodily gestures as a vehicle for architectural form-making. …

Generating Mass Housing Plans Through Gans - A Case In Toki, Turkey, Gi̇zem Özerol Özman, Semra Arslan Selçuk

Architecture and Planning Journal (APJ)

Nowadays, Machine Learning (ML) is frequently used in almost all disciplines having an intersection with technology. Recently, architects are using existing plan data sets in architecture through Deep Learning (DL) algorithms of big data to achieve generative and non-existent plan models by using ML. Especially, Generative Adversarial Neural Networks (GANs), one of the deep learning algorithms, have been in use in the creation of generative models for architectural studies. Within the scope of this paper, architectural drawings were generated by using GANs. This generation method allows for the training of spatial layout planning to networks and for the generation of …

Using Deep Learning To Generate Front And Backyards In Landscape Architecture, Mehmet O. Senem, Mustafa Koç, Hayriye E. Tunçay, İmdat As

Architecture and Planning Journal (APJ)

The use of artificial intelligence (AI) engines in the design disciplines is a nascent field of research, which became very popular over the last decade. In particular, deep learning (DL) and related generative adversarial networks (GANs) proved to be very promising. While there are many research projects exploring AI in architecture and urban planning, e.g., in order to generate optimal floor layouts, massing models, evaluate image quality, etc., there are not many research projects in the area of landscape architecture - in particular the design of two-dimensional garden layouts. In this paper, we present our work using GANs to generate …

Thus, in order to determine the estimated steel savings of this system as compared to the moment and braced frames, the four-story and eight-story buildings that are 96' × 96' in the plane and utilize …

Effects Of Color And Lighting Temperature On Mood And Cognitive Performance, Megan Afifi, Elizabeth Krumrei-Mancuso, Janet Trammell

Seaver College Research And Scholarly Achievement Symposium

Research on the psychological effects of design elements is of interest to designers, and even individuals, creating the experience of a space. Generally, warm colors like red and yellow are more stimulating and arousing than cool colors like blue and green, which are more relaxing and calming. Warm colors can also be distracting while cool colors help promote focus. Conversely, warm (orange-white) lighting positively influences mood more than cool (blue-white) lighting, but cool lighting can better promote productivity. No study thus far has analyzed the interaction of background color and lighting temperature on mood and cognitive performance.

We hypothesized that …

Inclusive Schools Design: A Phenomenological Investigation Into Visually Impaired Lived Experiences, Sarah Oteifa, Khaled Dewidar, Yasser Mansour

Architectural Engineering

Inclusive design is an approach that aims to include special children with the general student population by developing the whole system, including the built environment, to accommodate their needs. Although efforts have been made to include children with visual impairments in the educational mainstream, available design guidelines often miss their "real lived experience". Available inclusive school design criteria are considered limited and the necessary design qualities of space to cope with their impairments are often missing the phenomenological, holistic approach. This study is conducted using a mixed method. The necessary spatial qualities are extracted from visually impaired children's real experiences …

Raveling Performance Of Conventional And Rubberized Chip Seal Under Field And Laboratory Traffic Loading, Alireza Pourhassan, Ahmed A. Gheni, Mohamed Elgawady

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Raveling, or the Loss of Surface Aggregate, is a Major Concern in Chip Seal Pavement. Previous Studies Have Used the Standard Sweep, Vialit, and Pennsylvania Tests to Evaluate Raveling, But These Tests Do Not Replicate the Stresses of Rolling Vehicle Tires on Chip Seal and Have Produced Inconsistent Results. Additionally, These Tests Mainly Evaluate Early-Stage Raveling Due to their Short Curing Time. in This Study, a Small-Wheel Traffic Simulation Device (SWTS) Was Used to Apply Similar Stresses as Rolling Vehicle Tires and Produce Comparable Raveling Results. This Was Confirmed through a 13-Month Field Observation of Chip Seal, Where the Laboratory …

So, You Want To Build A Hangar?, Carla M. Fischer

Purdue Road School

Driven by corporate growth, companies are buying, maintaining, and piloting their own fleets of planes. Companies need a place to store and care for these multi-million-dollar assets, so the demand for corporate hangars is growing. But hangars aren’t like other commercial buildings; they have distinctive features from other structures.

Photolysis Of 3-Nitro-1,2,4-Triazol-5-One: Mechanisms And Products, Hunter W. Schroer, Esteban Londono, Xueshu Li, Hans Joachim Lehmler, William Arnold, Craig L. Just

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Insensitive munitions formulations that include 3-nitro-1,2,4-triazol-5-one (NTO) are replacing traditional explosive compounds. While these new formulations have superior safety characteristics, the compounds have greater environmental mobility, raising concern over potential contamination and cleanup of training and manufacturing facilities. Here, we examine the mechanisms and products of NTO photolysis in simulated sunlight to further inform NTO degradation in sunlit surface waters. We demonstrate that NTO produces singlet oxygen, and that dissolved oxygen increases the NTO photolysis rate in deionized water. The rate of NTO photolysis is independent of concentration and decreases slightly in the presence of Suwannee River Natural Organic Matter. …

Architecture And New Urbanism’S Relationship To Biomimicry And Floral Design, Alycia Timmerman

Honors Program: Senior Projects (Public)

The craft of floral design is classified as an art and a science. Similarly, architecture is rooted in the two disciplines. After conducting research and exploring biomimicry through the design process, it became evident that the process of design for architecture and floral design are similar. This relationship can also be extended into the field of planning and the New Urbanism movement. This study explores the integration of floral design and biomimicry with architecture and New Urbanism at the scale of the building and city block.

Close Mapping Of St. Olav’S Pilgrimage Path Through Gudbrandsdal Norway: Probabilities Of A Designed, Land Surveyed Concept Of A Large-Scale Christianised Landscape, Dennis Doxtater

International Journal of Religious Tourism and Pilgrimage

This exercise in Norway ‘close-maps’ accurate, existing geometries between thirty-two latitude / longitude points of mostly medieval churches and other sites on the major pilgrimage path through Gudbrandsdal to Trondheimsfjord where the martyr St.Olav was venerated. Site data and basic path routes are taken from the Pilegrimsleden website, popular today with religious or recreational tourists. The inclusion of the largest prehistoric monumental mound in Scandinavia as an important early stop on the pilgrimage provides the first clue to the eventual mapping of a large-scale ‘system’ of land surveyed patterns. This symbolic anchor in the south, is connected to likely ancient …

Planning, Preserving, And Increasing Accessibility: A Reflection On Going “Car-Free”, Abigail J. Weizer

City and Regional Planning

This paper studies the accessibility of car-free areas to those with mobility impairments by examining three car-free and car-lite experiments in California. Whether slowly converted to car-free with long-term, careful planning, or expeditiously changed to car-free during the COVID-19 pandemic, these three car-free experiments show the shortcomings of planning for accessibility in car-free spaces, and how instead of improving accessibility, current planning practice often hinders it. This paper offers a deep-dive into the drawbacks and benefits of going car-free and the ethical and legal reasons why urban planners, designers, and policymakers must consider the accessibility of a space before planning …

Precious Plastics - Plastic Brick Machine Fabrication, Timothy Ukaobasi Kanu, Evi Paraskevi Troulis

Architectural Engineering

The goal of this research is to determine the structural parameters of the recycled plastic polypropylene when molded into bricks resembling CMU blocks. To accomplish this, three mechanisms had to be assembled: the shredder, the injector, and the 1x1 mold. A tensile and compression test were to be performed on the plastic brick, and the values would be used to compare the tensile and compressive strength of PP plastic bricks, as well as their modulus of elasticity and stress vs. Strain performance. These values would be analyzed to determine whether it would be feasible to build an entire plastic wall. …

In recent years, procedural modeling techniques have been introduced to the urban planning discipline. By enabling the quick generation of design alternatives, these methods have the potential to expedite the public participation process. In this study, we explore ArcGIS CityEngine, an Esri procedural modeling software, and its application for depicting new missing middle housing developments in San Luis Obispo, California. Missing middle housing is an abstract planning concept and the public may benefit from 3D visualizations of the typology contextualized within their own neighborhood. To this end, we procedurally model two existing missing middle developments in San Luis Obispo and …

Airborne Infection Risks From Covid-19 In Meat Processing Plants And Different Solutions To Mitigate The Risks, Debayan Shom

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Meat processing plants are linked to the rapid spread of COVID-19 cases. A related literature review shows a lack of proper ventilation standards for the meat processing plants for workers’ health and safety. Ventilation rates in these plants are considered adequate if the meat products are unadulterated. Thus, the air distribution and ventilation rate experiments were conducted in three meat processing plants. These measured ventilation rates were either compared to ASHRAE Std. 62.1 (2019) for a similar space or the design values provided by the plant’s administration. The measured values were low in common spaces, such as the cafeteria and …
