Galvanized steel scrap flow and injection into the HIsarna reactor are investigated using discrete element method (DEM). The particle is fed through an inclined chute hits slag surface where zinc content evaporated solid particles melt. A DEM model setup validated experimental data obtained from exact plant‐scale geometry particles. Using model, effect of inclination, elevation, mode (batch con...

Like many transition economies, Slovenia is undergoing profound changes in the workings of the labor market with potentially greater flexibility in terms of both wage and employment adjustment. We investigate the impact of the changing labor market for Slovenia using unique longitudinal matched employer-employee data that permits measurement of employment transitions and wages for workers and l...

We study and compare different neural network learning strategies: batch-mode learning, online learning, cyclic learning, and almost-cyclic learning. Incremental learning strategies require less storage capacity than batch-mode learning. However, due to the arbitrariness in the presentation order of the training patterns, incremental learning is a stochastic process; whereas batch-mode learning...

This paper presents a study of the flow and thermal structures in the molten glass bath of a typical glass melting furnace with a throat but without air bubblers or electric boosting. Different separate effects on the flow structure of the glass melt are simulated, but only the glass melt is considered. The net heat flux distribution is imposed at the combustion space/glass melt interface, and ...

We present the design and experimental analysis of a dielectrophoretic trap composed of four microfabricated gold posts excited in a quadrupolar fashion. Using quantitative modeling tools, we have designed these extruded traps to attain strong holding against flow while being constrained by a set of system parameters. The extruded geometry consists of cylindrical electrodes in a trapezoidal arr...

International trade exposure affects job creation and destruction along the intensive margin (job flows due to expansions and contractions of firms’ employment) as well as along the extensive margin (job flows due to births and deaths of firms). This paper uses 1992-2010 yearly employment data from the universe of U.S. establishments to construct job flows at both the industry and commuting-zon...

The growth rates of workplace injury and illness rates exhibit a negative (time-varying) mean and a pro-cyclical response to variations in economic activity, as they decline in recessions before rebounding (and overshooting) during economic recoveries. Using a structural time series model, it is shown that this business cycle behavior is driven by job flows. In recessions, the acceleration of j...
