    Experimental and Simulation Analysis for the Impact of a Two-Link Chain with Granular Matter by Eliza A. Banu, Dan B. Marghitu

    Published 2015-01-01
    “…The resistance force of the granular matter is modeled as a linear superposition of a static (quadratic depth-dependent) resistance force and a dynamic (quadratic velocity-dependent) frictional force. The impact is defined from the moment the end point of the system comes in contact with the granular matter surface until the vertical linear velocity of the end point is zero. …”

    Neither “Platformization” Nor “Infrastructuralization”: Government as a Platform in China by Jingyan Elaine Yuan, Yuchao Zhao

    Published 2025-02-01
    “…Through a case study of “the digital reform” in Zhejiang Province, and the affiliated smart city project—City Brain—in Hangzhou, the municipal capital, this study draws on data from participatory observations and interviews to (1) provide a historical context, in which “platformization” in urban governance is aimed to serve market-oriented socio-economic reforms; (2) argue that such “platformization” is shaped by the long-standing structural tension between centralization and localism, which has been renewed by digital data flows; and (3) understand the shifting public–private demarcation in social interactions and arrangements to deflect continual frictions between the state, local agents, and platforms in the domain of digital governance.…”

    Comparison Study of Airway Reactivity Outcomes due to a Pharmacologic Challenge Test: Impulse Oscillometry versus Least Mean Squared Analysis Techniques by Elena Rodriguez, Charrell M. Bullard, Milena H. Armani, Thomas L. Miller, Thomas H. Shaffer

    Published 2013-01-01
    “…The technique of measuring transpulmonary pressure and respiratory airflow with manometry and pneumotachography using the least mean squared analysis (LMS) has been used broadly in both preclinical and clinical settings for the evaluation of neonatal respiratory function during tidal volume breathing for lung tissue and airway frictional mechanical properties measurements. Whereas the technique of measuring respiratory function using the impulse oscillation technique (IOS) involves the assessment of the relationship between pressure and flow using an impulse signal with a range of frequencies, requires less cooperation and provides more information on total respiratory system resistance (chest wall, lung tissue, and airways). …”
