Viscosity Stratified Turbulence: Insights From Direct Numerical Simulations, Quasilinear Reduction And Resolvent Analysis, Pulkit Kumar Dubey

Doctoral Dissertations

This dissertation focuses on wall-bounded shear-driven turbulence with temperature-dependentviscosity. Direct numerical simulations and quasilinear reduction have been used to establish the asymmetric variation of turbulent statistics in the wall-normal direction. A comparison of energy spectra in the cold and hot halves of the channel reveals that large scale motions are amplified in the more viscous half while small scale motions are amplified in the less viscous half. Interestingly, the threshold wavenumber distinguishing these scales remains independent of stratification. This observation has been verified via a low-order reconstruction of the turbulent kinetic energy profile using resolvent analysis. Fourier modes that selectively …

Ai And Tribal Court Practice, Matthew L.M. Fletcher

Articles

American Indian tribal court practice resides at the intersection of two difficult legal problems. First, because tribal justice systems are usually very young and dynamic, awareness and analysis of tribal law is underdeveloped. Second, because tribal nations are not governed by state or federal law, tribal law is culturally unique. Tribal court practitioners often find that even routine legal matters will involve questions of first impression in the jurisdiction. All of this is to say tribal court jurisprudence is intensely jurisgenerative.

Because tribal law is often unsettled or indeterminate, the costs of discovering and applying this law are occasionally high. …

Clinicians In The Loop Of Medical Ai, W. Nicholson Price Ii

Articles

As medical AI begins to mature as a health-care tool, the task of governance grows increasingly important. Ensuring that medical AI works, works where it’s used, and works for the patient in the moment is a challenging, multifaceted task. Some of this governance can be centralized—in review by FDA or by national accreditation labs, for instance. Some must be local, performed by the hospital or health system about to use the product in their own, unique environment. But a large amount of governance is left to the individual provider in the room, the human in the loop who presumably knows …
