Mechanistic framework for reduced-order models in soft materials: Application to three-dimensional granular intrusion by Agarwal, Shashank, Goldman, Daniel I., Kamrin, Ken

“…Soft materials often display complex behaviors that transition through apparent solid- and fluid-like regimes. While a growing number of microscale simulation methods exist for these materials, reduced-order models that encapsulate the macroscale physics are often desired to predict how external bodies interact with soft media. …”

The Matter of the Hold: Housing futures and the paradigm of the ship by Donovan, Inge, Pankhurst, David

“…In light of the increasing shift towards buildings as storehouses of material to be held for future reuse, and as vessels of carbon sequestration, our thesis explores how design for the uneven, yet cyclical ebbs and flows of renewable resources erodes architecture’s traditionally rigid temporal boundaries of planning, construction, and occupancy, and produces temporally dynamic regimes of figure and form. The collection, administration and reconfiguration of waste materials results in the creation of new, regenerative forms of collective living that challenge the boom-and-bust logic of investment in public infrastructures.…”

Crack healing in reactive MgO-slag system via bacteria induced carbonate precipitation by Zheng, Yanying

“…In this study, crack healing in reactive MgO-slag system was investigated via bacteria induced carbonate precipitation. Self-healing regimes such as alternating bacteria medium soaking and carbon dioxide curing cycles and alternating water and carbon dioxide cycles were adopted in this project. …”

Isentropic diagnostics of mean circulation and water vapour budget for the Asian monsoon by Lee, Shao Yi

“…These comparisons may not reflect the actual dynamical regimes that local “Hadleys” lie in, because the global zonal mean meridional circulation is not representative of the meridional circulation in the monsoon and oceanic regions. …”

Characterization of structural and optical properties of Zinc Oxide thin films by Liu, Yuchan

“…The objective of this thesis is to determine the optical properties of ZnO thin films with spectroscopic ellipsometry in a wide spectral region covering the both regimes of below and above the ZnO bandgap. Three dispersion models, namely, Sellmeier dispersion model, Cauchy model and Forouhi-Bloomer model, were used and evaluated to determine the optical constants of ZnO thin films below the energy band gap. …”

Investigating whether executive functioning, working memory capacity, & long-term memory can be improved by cognitive training by Lim, Ming Ze

“…Paired-sample t-tests indicated that two training regimes (i.e., daily meditation training and practicing retrieval) led to changes that improve participants’ ability to store and retrieve episodic information formed while reading text passages. …”

Network analysis and data science for finance: from traditional markets to decentralised exchanges by Miori, D

“…Otherwise, we study returns of an heterogeneous set of indices belonging to multiple asset classes, and characterise their network of evolving correlations to identify market regimes that are found to have distinguishable macroeconomic features. …”

Conservation planning in Europe: ecological, financial, and political challenges by Hannemann, H

“…Probably unsurprisingly, the distribution of biodiversity in Europe mostly does not match political entities, all of which have individual aims, financial resources, and biodiversity management regimes in place. All have a significant impact on biodiversity conservation planning because i) the use of geo-politically truncated data influences modelling predictions, ii) financial commitment to biodiversity conservation varies between countries influencing success outcomes, iii) biodiversity persistence in current and future climate change does not recognise geo-political boundaries, and iv) many of the key environmental frameworks are implemented within countries and do not considering trans-boundary issues.…”

Ammonia volatilization from urea as affected by tropical‐based palm oil mill effluent (Pome) and peat by Siva, K. B., Aminuddin, H., Husni, M. H. A., Manas, A. R.

“…The organic materials were separately matrixed with urea into pelletized form and evaluated under laboratory regimes for the per cent NH3 volatilization, pH change, and ammonium-nitrogen (NH4-N) recovery. …”

Dynamics of time-modulated, nonlinear phononic lattices by Kim, Brian L., Chong, Christopher, Hajarolasvadi, Setare, Wang, Yifan, Daraio, Chiara

“…In the present work, the response of a one-dimensional phononic lattice with time-periodic elastic properties is studied with experimental, numerical and theoretical approaches in both linear and nonlinear regimes. The system consists of repelling magnetic masses with grounding stiffness controlled by electrical coils driven with electrical signals that vary periodically in time. …”

Kinetic subspace investigation using neural network for uncertainty quantification in nonpremixed flamelets by Koenig, Benjamin C, Ji, Weiqi, Deng, Sili

“…However, this one-dimensional assumption does not apply to all flamelet regimes. In the current work, we developed a systematic approach to discover low-dimensional active subspace reductions that apply to the entire mixture fraction space of the flamelet, and that function even in cases where the uncertainty response is not uniform across the entire solution domain and the one-dimensional assumption does not apply. …”

Privacy: a political approach by Bogue, RC

“…It can thus be shown that a commitment to democracy entails a commitment to certain privacy rights—a finding that circumvents the difficulty in establishing a common basis for privacy protections by appealing to all citizens who live under democratic regimes. In abandoning familiar understandings of privacy, the political approach to privacy does away with the problematic emphasis on consent, adapts privacy to an ever-changing surveillance environment, addresses prominent critiques of privacy rights, and provides a common basis of justification for future privacy legislation. …”

Temporal evolution of mechanical properties in PDMS: A comparative study of elastic modulus and relaxation time for storage in air and aqueous environment by Zhang, Y, Adam, C, Rehnstrom, H, Contera, S

“…The identification of two distinct relaxation times suggests the involvement of two disparate material property regimes in the relaxation process, implying changes in the surface material composition at the interface with air/water. …”

High-throughput quantification of quasistatic, dynamic and spall strength of materials across 10 orders of strain rates by Eswarappa Prameela, Suhas, Walker, Christopher C, DiMarco, Christopher S, Mallick, Debjoy D, Sun, Xingsheng, Hernandez, Stephanie, Sasaki, Taisuke, Wilkerson, Justin W, Ramesh, KT, Pharr, George M, Weihs, Timothy P

Plan Implementation Challenges in a Shrinking City: A Conformance Evaluation of Youngstown’s (OH) Comprehensive Plan With a Subsequent Zoning Code by Ryan, Brent D., Gao, Shuqi

“…Informants attribute the weak conformance between the comprehensive plan and the Youngstown Redevelopment Code to many of the former’s ideas not being legally defensible. Changing political regimes, shifts in public opinion, and the driving need for economic investment were also cited as contributors to this weak conformance. …”

Mechanics of Three-Dimensional Micro-Architected Interpenetrating Phase Composites by Chen, Andrew Y.

“…Using these prototypes, we study the mechanical behavior of the fabricated composites under uniaxial compression, with particular emphasis on the non-linear and failure regimes. We show that independent of the material system, the presence of a load-bearing matrix distributes the stress in the composite, contributing to a high-strength, globally stretchingdominated failure behavior, regardless of nodal connectivity. …”
