This study investigates the epistemological potentials of parametric analysis for digitally modeling ordinary, existing buildings, addressing a gap in architectural research. While traditional digital prioritizes geometric accuracy, it often limits ability to generate new insights, treating models as static representations rather than tools knowledge production. research challenges assumption that accuracy is necessary validity, proposing hypothesis-generating tool capable uncovering latent...
Abstract An outstanding concern raised over the implementation of liquid metal plasma facing components in fusion reactors is potential for ejection into plasma. The influences Rayleigh–Taylor-like and Kelvin–Helmholtz-like instabilities were experimentally observed quantified on thermoelectric-driven liquid-metal plasma-facing structures (TELS) chamber at University Illinois Urbana–Champaign. To probe stability boundary, currents velocities first characterized with a flush array. Subsequent...
Steady-state fusion power plant designs present major divertor technology challenges, including high heat flux both in steady-state and during transients. In addition to these concerns, there are the unresolved issues of long term dust accumulation associated tritium inventory safety issues. It has been suggested that radiation-based liquid lithium (LL) concepts with a modest lithium-loop could provide possible solution for outstanding reactor issues, while potentially improving plasma...
This paper demonstrates a CMOS compatible process integration of spin-orbit torque (SOT) device with unique bi-layer SOT bottom electrode. An effective spin-Hall angle 0.27, median tunneling magneto-resistance ratio 127% at electrical CD 57 nm, and 96% resistance-based MTJ yield on 300 mm scale were achieved. We experimentally validated the two-pulse field-free switching scheme spin-transfer assist 10 ns. Unlike conventional schemes, demonstrated adds no complexity to integration.
The use of low atomic number liquid metals has been shown to have the potential solve many prevalent problems like erosion and radiation losses associated with interaction fusion plasma facing component (PFC) structures in tokamaks. Since first evidence lithium increasing performance TFTR [1], benefits using environments seen devices, including CDX-U [2], NSTX [3], LTX [4], DIII-D [5]. While both fast flow slow concepts studied regards wall alternatives, this report will focus on efforts...
Impingement of high fluxes helium ions upon metals at elevated temperatures has given rise to the growth nanostructured layers on surface several metals, such as tungsten and molybdenum. These grow from bulk material have greatly increased area over that a not surface. They are also superior deposited nanostructures due lack worries adhesion differences in properties. Several palladium samples varying thickness were biased exposed helicon plasma. The characterized function layer temperature....
This reflection paper considers the epistemological implications of constructing a digital model an existing building. The compares, in detail, three distinct approaches to New Sacristy at S. Lorenzo Florence, Italy. Each explores effects problematizing model-building duality. problematization implicates two conventional assumptions about existing-building models, namely, that they must be geometrically accurate and semantically predictable order useful for research purposes. Proposed...
Purpose This project examines digital modeling strategies for existing buildings. In this context, it aims to question assumptions about the need geometric accuracy and efficacy of predefined ontologies. As a counterpoint prevailing strategies, proposes approach using project-specific, emergent ontology. Design/methodology/approach Nishiki Market, in Kyoto, Japan, is studied as test case. The emergent-ontology process introduced with an initial minimal set operations including basic fold...

Methods that plan to recover tritium from liquid lithium require intimate knowledge of the surface, sub-surface, and bulk chemistry associated with interactions between hydrogen isotopes particles. Focusing on lithium–lithium hydride system, previous studies have been able determine concentrations liquidus curve, which separates dissolved in solution (known as phase) precipitates out phase). Knowledge how these phases coexist melts is particularly important when exposed a hydrogen,...
In this paper the design and execution of a simple AutoLISP routine for generating map plan isovists (in sense Benedikt) are discussed. Such field is registration visibility from multiple station points within around building. More precisely, records cumulative effect, over spatial matrix, occluded vision distant horizon. Thus, termed an occlusion map. An registers effect which observer's position in space has on their perception architecture's visual permeability. Occlusion maps shown here...
Abstract Advances in building information modeling (BIM) deeply impact the production of new architecture; its benefits are obvious and acceptance widespread. But how does BIM study existing architecture? Can be assumed to operate as a neutral framework, equally applicable architecture anywhere? Using point departure recent outline conceptual structure parametric prepared by Sacks, Eastman, Lee (2004), this paper compares models two works architecture: Mies van der Rohe's Crown Hall Peter...

Test structures patterned in novel geometries lower wiring RC are fabricated, electrical measurements compared to simulated values from material geometrical parameters. Circuit studies with representative examples of such interconnects were performed quantify the benefit microprocessor performance power.
This project contributes to architectural epistemology – that is, the study of ways in which knowledge may be created, organized, and disseminated. Within context, addresses digitally modeling existing buildings for purposes conducting geometrically-based analysis. The focuses on parametric analysis, defined here as a way examining foregrounding latent formal conditions within digital models buildings. Parametric analysis encompasses three approaches: generative, dissective, morphological,...
