Syracuse University in June 2005 announced a team selected to design the Syracuse Center of Excellence in Environmental and Energy Systems (SyracuseCoE) headquarters. The design team for SyracuseCoE, a collaborative industry-university organization dedicated to studying IAQ, human performance, and renewable energy in the built environment, was tasked to create a 55,000-sq-ft, five-story tower and a double height lab wing to house their various labs, classrooms, and mechanical spaces. The design team was expected to develop a LEED Platinum building and beyond using the USGBC's LEED NC 2.2 rating system. The design team accomplished the heat rejection from the heat pumps by a closed loop geothermal bore field. Space dewpoint temperature was constantly being monitored by the Siemens BMS to avoid condensation, which is especially pertinent when operating in the natural ventilation mode.

Aiming to study the temperature field changes, the House VI project was checked. This house is located in Vila37, Rio de Janeiro, Brazil, a dead-end small street with only one inlet/outlet. In the houses of Vila37, the indoor ventilation is restricted to the facade windows. Giving the impossibility of introducing cross-ventilation in a traditional way, a short wind-catch was previously added with positive results;therefore, simulations with long wind-catch are being carried out. The analysis started by solving the air-circulation problem by using a finite element method and after, with the wind fields added, the heat transfer problem was analysed. The results obtained were evaluated and compared with the previous ones.

Three-dimensional (3D) representation of cultural heritage in a digital environment is coming into prominence for documentation of geometric and semantic details and the interpretation of shape representation from academic studies to commercial practices. To interpret cultural and historical shapes, the use of the computational medium is expanding with developing technologies. Advanced 3D design and development applications appear every day with distinct functions. However, not every technology provides designers a convenient medium to create, explore, and think naturally. In that sense, digital design mediums and tools become important to enhance the interactivity level with cultural heritage for designers through different interfaces. Particularly, the utilities of design interfaces are essential for preserving reconstructing ruined cultural heritage in the digital design mediums. In this study, we investigate the designers’ creative design process in the context of shape representation methods within the possibilities of two different 3D design interfaces as a computer and virtual reality (VR) interfaces. At first, we conducted a shape exploration exercise to generate the 3D model pieces of the Dark Church in Cappadocia. And then, we used the generated 3D model pieces in a shape representation exercise to observe the seeing, imagining, and acting abilities of designers in computer and VR environments. © 2021, Springer Nature Switzerland AG.

Estimating directions of arrival (DoAs) of multiple sound events still poses challenges in noise control engineering. This paper reviews recent developments in model-based direction-of-arrival analysis using three different microphone arrays, in situations potentially involving multiple concurrent noise sources. The microphone array configurations discussed in this paper include a sparse arrangement consisting of only two microphones, and more sophisticated configurations consisting of multiple microphone channels in the form of coprime linear arrays and spherical arrays. To cope with DoA analysis challenges using the model-based approaches, formulation and evaluation of prediction models are of central importance. Both noise source enumeration and direction of arrival estimation present important challenges in the noise DoA analysis of all three types of microphone arrays. The prediction models, based on specific array configurations, are evaluated upon experimental data derived from pertinent array signal processing in order to determine the most concise model that can adequately predict the experimental data, thereby estimating first the concise number of noise sources, then their DoA information. This paper reviews the prediction models recently established for the three microphone arrays, the two levels of model-based analysis, and experimental results. © Proceedings of 2020 International Congress on Noise Control Engineering, INTER-NOISE 2020.

The present paper demonstrates and discusses a potential of steel latticed plates to use as seismic walls, through experimental study. Cyclic shear load tests of five steel latticed plates, composed of equilateral triangular grids, were conducted to investigate buckling and post-buckling strength and ductility. Three of five plates yield out-of-plane overall buckling and the rest in-plane member buckling as predicted. The buckling and post-buckling strengths can be approximated using the generalized slenderness calculated by linear buckling analysis and its function for inelastic strength, regardless to the buckling mode. Moreover, these latticed plates show good ductility and energy dissipation capacity But a disadvantage that the buckling deformation is too observable is also exposed.

Swirling Instability Mediated by Elastic and Hydrodynamic Couplings in Cytoplasmic Streaming

Cytoplasmic streaming is driven by molecular motors that move along the cytoskeleton and entrain the surrounding fluid. In certain cell types, the direction of cytoplasmic streaming is not predefined but rather stochastic. For example, in meiotic cytoplasmic streaming of Caenorhabditis elegans zygotes, the direction of the swirl reverses over time [Kimura et al., Nat. Cell Biol. 19, 399 (2017) ]. While a mean-field theory explained the reversal, the structure of flows in three-dimensional space and the mechanical role of the endoplasmic reticulum (ER) remains unknown. To test the hypothesis that the elastic ER bonds and hydrodynamic interactions between microtubules mediate the orientational order of microtubules, leading to directional cytoplasmic streaming, we computationally investigated fluid-structure interactions in cytoplasmic flow, ER networks, and microtubule structures in the presence of microtubule dynamic instability. The results indicate that the occasionally reversing swirls emerge within a certain range of ER elasticity, and our experimental measurements of the ER elasticity agree with the numerical predictions. Mass transport analysis further demonstrates that the reversing swirls are suitable for intracellular particle mixing. These findings illustrate the delicate balance of meiotic cytoplasmic streaming and provide insights into the physiology of the embryogenesis.

This research aims to generate architectural design recommendations based on the visual reconstruction of the Lalitavistara reliefs from Borobudur, addressing the urgent need for building designs that retain the distinctive character of Nusantara architecture. The proposed design is intended for application in Ibukota Nusantara Indonesia, integrating smart city and green city approaches while featuring a unique visual style that incorporates historical artifacts. This need arises from the current trend of building designs in Ibukota Nusantara Indonesia, which predominantly adopt an international style and lack the unique elements of Nusantara architecture. To address this, the research adopts a project-based methodology, utilizing blueprints derived from reconstructed Lalitavistara relief panels, developed through 3D modeling and further enhanced by digital imaging with the assistance of Artificial Intelligence (AI). The expected outcome of this study is to provide a method for designing buildings that showcase a distinctive Nusantara-Indonesian style, along with recommendations for a digital design workflow supported by AI to finalize 3D modeling visuals. © 2024 IEEE.

Diffuseness, an important room acoustics parameter, is not easily quantified. Most current methods that attempt to define a single number to describe a room's level of diffuseness require highly specialized equipment or broad estimations. Multifractals present a recent mathematically robust method that may allow diffuseness to be quantied by analyzing a single room impulse response [S.J. Loutridis, "Quantifying sound-field diffuseness in small rooms using multifractals", JASA (125)(3)(2009)]. This method will be verfied by measuring a room in several states generally considered to affect diffuseness. The method has only thus far been demonstrated in small rooms, and its applicability towards a large concert hall is tested. Frequency dependence is investigated as well as the effects of the measuring location within the room. © 2009 Acoustical Society of America.
