Toward an Environmental Database: Exploring the material properties from the point cloud data of the existing environment
No full textThe utilization of point cloud as a 3D laser scanning product has reached acrossmulti-disciplines in terms of data processing, data visualization, and dataanalysis. This study particularly investigates further the use of typical attributesof raw point cloud data consisting of XYZ (position information), RGB (colourinformation) and I (intensity information). By exploring the optical and thermalproperties of the given point cloud data, it aims at compensating the material andtexture information that is usually remained behind by architects during theconceptual design stage. Calculation of the albedo, emissivity and the reflectancevalues from the existing context specifically direct the architects to predict thetype of materials for the proposed design in order to keep the balance of thesurrounding Urban Heat Island (UHI) effect. Therefore, architects can have acomprehensive analysis of the existing context to deal with the microclimatecondition before a design decision phaseDesign Informatic
Robotic Materialization of Architectural Hybridity: Modelling, Computation and Robotic Production of Multi-materiality
No full textConsidering both architectural and constructional aspects of the built environment, hybridity or multi-materiality is essential to generate functional habitable spaces. Buildings consist of subsystems that each require different and sometimes conflicting material attributes and behaviours. In this context, expanding the solution space for material properties in architectural applications can be achieved through the integration of innovative design computation and production methods. With this focus, the paper presents prototyping processes and frames a discourse on robotic materialisation of architectural hybridity, ranging from micro or material to macro or component scales. The paper discusses three case studies, each with a specific focus on digital modelling, computation and robotic production of hybrid systems. The conclusion outlines how robotic fabrication of architectural multi-materiality redefines, informs and tends methods of design computation and materialisation.Architectural EngineeringDigital ArchitectureTeachers of Practic
Theatrical Performance as Experimental Architecture
No full textThis paper discusses by way of the authors' recent projects how improvised livedance performance, architectonic composition, and sensing technology converge and inform new opportunities in architectural experimentation. We first lay out the theoretical basis of technology in architectural experimentation in "new rationalities" of technologically augmented aesthetic work. We then briefly describe two projects, X-Change Room and RaumSubsTANZ and the motives behind them. X-Change Room deals with /non-verbal/ ambient display of information and interaction through envelope threshold. RaumSubsTANZ, a short interactive dance composition that highlights the ephemerality of architectural composition augmented by interaction devices. Through the two small projects we attempt to explore a specific technological milieu and reflect on the potentials and challenges of experimentation in architectural composition. The paper presents design methods and techniques that incorporate theories of perception and semiotics by way of an umbrella concept, "ambient displays" and interactive composition. Ultimately, we explore non-verbal communication and theatrical performance as architectural informant that augments semiosis and cognition that pertains to the role of technology at the intersection of primordial senses, cerebral technology, and place-making.OLD Public Buidin
Analysis of an N-Port Consisting of a Radial Cavity and E-Plane Coupled Rectangular Waveguides
No full textAn analysis of an n-port including a radial or coaxial cavity and E-plane coupled rectangular waveguides is presented. A nonstandard field matching technique which exploits both circular and rectangular boundaries, is used to determine the scattering matrix parameters of the n-port. Validity of the analysis is verified through comparison with an alternative analysis and experiment
Analysis Of A Planar M-way Radial Waveguidie Combiner/ Divider For The Case Of Arbitrary Excitation

No full textAnalysis of a Coaxial-to-Waveguide Adaptor Incorporating a Dielectric Coated Probe
No full textAn analysis of a coaxial-to-waveguide adaptor that incorporates a solid probe, coated with a dielectric is presented. Based on this analysis, a computer algorithm for an IBM PC is developed. The numerical results for the input impedance of the probe are presented and show good agreement with the other analyses and experiments
Improving the Online Design Education Experience
No full textDesign education usually takes place in a studio setting, in which visual and spatial artefacts are produced, shared, improved, presented and commented. This specific setting comes with qualitative properties that allow for situated learning with object-oriented focus and interaction, combined with a rich collegial context in which ideas can flourish and certain values and ethics are cherished. Using our education platform for online learning, we noticed the lack of support for typical creative and social design studio aspects, while factual classroom education was well supported. This paper describes how we attempt to translate the qualities of the studio education setting into an online environment for design education. Our approach is not to build a Virtual Design Studio (VDS) from the bottom up, but instead, to build on top of our universities' online education platform of choice. The paper commences with a short description of design education in a studio setting. Then a number of basic principles of design studio education is applied to the development of two Massive Open Online Courses (MOOCs). In the last section we discuss the different setups and compare the online aspects with on campus design studio education.OLD Form and Modelling StudiesTeaching & Learning Service
A Simple Analysis of a Symmetric Waveguide Five-Port Junction
No full textA simple analysis of a symmetric waveguide five-port junction is described.
