-In storm waterways and at dam outlets, high-velocity supercritical flows are characterized by substantial air bubble entrainment. The entrainment of fine air bubbles and the strong turbulent mixing contribute both to the air-water transfer of volatile gases (e.g. oxygen, nitrogen, VOC). The paper describes new experimental data obtained in a 25 m long channel with a 4 ° slope. The analysis of ...

The concept of peer-to-peer (P2P) energy trading leads to the flexible transaction prosumers and consumers, for which P2P business model is normally main attention. It still requires system operators address challenges in constraint problems. In this context, work regards congestion conjunction with trading. Firstly, a matching approach based on cost path proposed. consistent dispatch along eac...

We integrate local labor market data on worker flows (accession and separation rates), job flows (creation and destruction rates), employment levels, and earnings with MSA-level data on housing prices and local area unemployment, in order to study the local labor market dynamics associated with the U.S. housing price bubble of the late 2000s. We proceed to study the magnitude and timing of the ...

The PHOENICS code is employed to perform numerical simulations of gas-liquid two-phase bubbly flows in large vertical flow channels. Air-water and steam-water flows in large diameter pipes are simulated using the built-in two-fluid option of the code where liquid and gas are modeled as two interacting continua. The code is utilized in conjunction with advanced twophase flow models, accounting f...

Measurements of air–water flow properties are reasonably simple in steady flows, but not so in unsteady flows. Some studies investigated periodic flows in which instantaneous data were averaged over several cycles. During the present work, new unsteady air–water flow measurements were performed in sudden open channel flow surges. Unsteady air–water flow measurements were performed in the wave f...

In recent years, many Computer Science undergraduate programs have had to address declining enrollment. While the reasons behind the decline are complex: the dot-com bubble burst, the way we train students, the lack of intellectual excitement, and so on, educators are creatively trying to broaden students’ interests in computing. In this paper, we present our plan to use some AI concepts, espec...

The Σ-method for structural analysis of a differential-algebraic equation (DAE) system produces offset vectors from which the sparsity pattern of DAE’s system Jacobian is derived; this pattern implies a fine block-triangular form (BTF). This article derives a simple method for quasilinearity analysis of a DAE and combines it with its fine BTF to construct a method for finding the minimal set of...

We calibrate the Baryonic Tully-Fisher (BTF) Relation using a sample of gas dominated galaxies. These determine the absolute scale of the baryonic mass–rotation speed relation independent of the choice of stellar mass estimator. We find a BTF slope of 3.94±0.07 (random)±0.08 (systematic) and a zero point of 1.79±0.26 (random) ±0.25 (systematic). We apply this relation to estimate the stellar ma...

Recent measurement devices for the Bidirectional Texture Function (BTF) offer high parallel capture of the spatial varying reflectance data for material samples. We present an approach to use measurement data from homogenous materials or materials with stochastical mesostructure to obtain data samples for the fitting of BRDF models like CookTorrance. We applied this approach to measured samples...

The process of microbubble filtration from blood is complex and highly dependent on the forces of flow and buoyancy. To protect the patient from air emboli, arterial-line filters commonly use a micropore screen, a large volume housing with purpose-built shape, and a purge port to trap, separate, and remove circulating microbubbles. Although it has been proposed that an insufficient buoyancy for...
