Ultracapacitors (UCs) are the focus of increasing attention in electric vehicle and renewable energy system applications due to their excellent performance in terms of power density, efficiency, and lifespan. Modeling and parameterization of UCs play an important role in model-based regulation and management for a reliable and safe operation. In this paper, an equivalent circuit model template ...

<div><p>Dialog state tracking (DST) plays a critical role in cycle life of task-oriented dialogue system. DST represents the goals consumer at each step by and describes such objectives as conceptual structure comprising slot-value pairs actions that specifically improve performance effectiveness systems. faces several challenges: diversity linguistics, dynamic social context dissem...

Using the continuous Dst data available since 1957 and H component data for the Carrington space weather event of 1859, the paper shows that the mean value of Dst during the main phase of geomagnetic storms, called mean DstMP, is a unique parameter that can indicate the severity of space weather. All storms having high mean DstMP (≤−250 nT), which corresponds to high amount of energy input in t...

In this paper, dynamic and stability analysis of a flexible cam-follower system is investigated. Equation of motion is derived considering flexibility of the follower and camshaft. Viscous and Coulomb frictions are considered in the rocker arm pivot. The normalized equation of motion of the system is a 2nd- order differential equation with periodic coefficients. Floquet theory is employed to s...

It is the aim of work in theoretical cognitive science to produce good theories of what exactly cognition amounts to, preferably theories which not only provide a framework for fruitful empirical investigation, but which also shed light on cognitive activity itself, which help us to understand our place, as cognitive agents, in a complex causally determined physical universe. The most recent su...

Disinhibited activity of the hypothalamic-pituitary-adrenocortical (HPA) neuroendocrine system, characterized most specifically by abnormal responses to the dexamethasone suppression test (DST), is observed in 40-50% of patients with endogenous depression. The heterogeneity of endogenous depressives with respect to this neuroendocrine marker is so far unexplained. A recent report from Iowa sugg...
