This paper presents the trilogy of virtual classifications, the speculative environment, the virtual inhabitant and the virtual built-form. These combine, generating a new realm of design within immersive architectural space, all to be designed relative to each other, this paper focuses on the speculative environment portion. This challenged computational design and representation through atmospheric filters, visible environment boundaries, materiality and audio experience. The speculative environment was generated manipulating the physical laws of the physical world, applied within the virtual space. The outcome provided a new spatial experience of architectural dynamics enhanced by detailed spatial qualities. Design concepts within this paper suggest at what immersive virtual reality can evolve into. Following an interconnective design methodology framework allowed a high level of complexity and richness to shine through the research case study throughout the process and final dissemination stages.

Engineering education has been evolving over the last few decades to include more engineering design courses in the curriculum or offer a new degree altogether that allows one to design a unique degree suited to his or her own interests and goals. These new engineering curricula produce engineers with strong backgrounds in fundamental engineering and design knowledge, which make them strong candidates for solving complex and multidisciplinary engineering problems. Many universities have embraced the need for multidisciplinary engineers and have developed interdisciplinary engineering design courses for many experience levels. Such courses build a foundation in engineering design through a unique series of lectures, real-world examples and projects, which utilize validated design tools and methodologies. This paper assesses the value of using design tools, web-based and downloadable, in undergraduate interdisciplinary design engineering courses. Six design tools are tested for their ability to increase the student’s knowledge of six design concepts. Also, the tools are evaluated for ease of use and if the different digital formats affect their educational impact. It was found that most students valued all the design tools and that the tools reinforced all but one design concept well. Quotes from the open-ended portion of the survey demonstrate the acceptance of the design tools and a general understanding of the importance of engineering design. The design tools, design concepts course goals, survey questions and survey results are discussed.

Key Concepts

New media and methodologies are being employed in changing the conceptual understanding of what digital design is and may become. New experience is beginning to emerge in relation to novel key design concepts, computational methods, and digital technologies in the use of, and interaction with, digital media in design. The chapter describes an experimental program, the objective of which was to identify and map novel design concepts and relevant methodologies of digital design. In making the survey, analysis, and the categorization of relevant concepts and emerging precedents in this field, the authors made an attempt to formulize a theoretical basis for the conceptual mapping of this field. The conceptual mapping of this field is termed DDNET: Digital Design Network. The DDNET is a semantic system divided into the following conceptual levels: Key-concepts, sub-concepts, computational models and techniques, and precedent level. As a first step in this research, the authors made a survey of emerging knowledge from both praxis and theoretical resources, and then formulated and presented proposed set of design models, concepts, relevant methodologies, and precedents. Next, the authors mapped a network representation around leading key-concepts. The final step was to accommodate and apply this representation as a new basis for a pedagogical experiment in teaching digital design. The research has been conducted in Experimental Digital Design Studio in the Faculty of Architecture and Town Planning at the Technion, Israel.

Our society has witnessed major growth and innovation in technology. However, one of innovation’s fundamental aspects, designer creativity, is still largely unsupported by information technology (IT) tools. This paper establishes a bridge between efforts to use cyberinfrastructure to generate design alternatives and a designer’s ability to explore and evaluate concepts. The research presented provides a method of synthesizing a web-based representation of a product concept using information from a digital design repository, an automatic concept generator, and results from a clustering analysis. A visualization interface is developed to provide designers with multiple representations of product concepts. The development of this approach establishes a computing infrastructure to support an investigation into the effect of information technology on designer creativity and provides a foundation for the development of further support technology. The architecture is implemented and the result is illustrated with an example in order to show the capabilities of the approach.

Quantifying the ability of a digital design concept to perform a function currently requires the use of costly and intensive solutions such as computational fluid dynamics. To mitigate these challenges, the authors of this work propose a deep learning approach based on three-dimensional (3D) convolutions that predict functional quantities of digital design concepts. This work defines the term functional quantity to mean a quantitative measure of an artifact's ability to perform a function. Several research questions are derived from this work: (i) Are learned 3D convolutions able to accurately calculate these quantities, as measured by rank, magnitude, and accuracy? (ii) What do the latent features (that is, internal values in the model) discovered by this network mean? (iii) Does this work perform better than other deep learning approaches at calculating functional quantities? In the case study, a proposed network design is tested for its ability to predict several functions (sitting, storing liquid, emitting sound, displaying images, and providing conveyance) based on test form classes distinct from training class. This study evaluates several approaches to this problem based on a common architecture, with the best approach achieving F scores of >0.9 in three of the five functions identified. Testing trained models on novel input also yields accuracy as high as 98% for estimating rank of these functional quantities. This method is also employed to differentiate between decorative and functional headwear, which yields an 84.4% accuracy and 0.786 precision.

Digital technology and its use in architecture support the construction industry in transitioning to more sustainable building development. Digital technology is widely taught in architecture programs in China, but there are few consistent strategies for combining digital architectural design with traditional architectural design in architectural education. Consequently, sustainable design concepts are not included in digital architectural design courses, and thus architectural education is not concerned with sustainable development. In this paper, we focus on the teaching of digital design in architecture and investigate how digital architectural design teaching can incorporate sustainability. Data from 15 universities were qualitatively analyzed, leading to the development of four models of teaching digital architectural design. Development of the models revealed that there are three increasing levels in digital architectural design teaching and that there is a close relationship between the teaching level and the transfer of architectural knowledge. This recognition led to the development of a single comprehensive model of digital architectural design teaching that is universally applicable. This research increases our understanding of digital architectural design teaching in architecture programs and strengthens the multi-level connections between digital architectural design teaching and designing and constructing sustainable built objects.

With the introduction of field-emission sources and “immersion-type” objective lenses, the resolution obtainable with modern scanning electron microscopes is approaching that obtainable in STEM and TEM-but only with specific types of specimens. Bulk specimens still suffer from the restrictions imposed by internal scattering and the need to be conducting. Advances in coating techniques have largely overcome these problems but for a sizeable body of specimens, the restrictions imposed by coating are unacceptable.For such specimens, low voltage operation, with its low beam penetration and freedom from charging artifacts, is the method of choice.Unfortunately the technical dificulties in producing an electron beam sufficiently small and of sufficient intensity are considerably greater at low beam energies — so much so that a radical reevaluation of convential design concepts is needed.The probe diameter is usually given by
