The emission and collection of current from satellites or rockets in the ionosphere is a process which, at equilibrium, requires a balance between inward and outward currents. In most active experiments in the ionosphere and magnetosphere, the emitted current exceeds the integrated thermal current by one or more orders of magnitude. The system response is typically for the emitted current to be...

Multiuser receivers improve the performance of spread-spectrum and antenna-array systems by exploiting the structure of the multiaccess interference when demodulating the signals of a user. Much of the previous work on the performance analysis of multiuser receivers has focused on their ability to reject worst-case interference. Their performance in a power controlled network and the resulting ...

A well-known shortcoming of rational voter models is that the equilibrium probability that an individual votes converges to zero as the population of citizens tends to infinity. We show that this does not – as is often suggested – imply that equilibrium voter turnout is insignificant in the limit. We characterize limiting equilibrium turnout and show that it may actually be arbitrarily large. I...

This paper focuses on experimental results to prove that motor current signature analysis (MCSA) can diagnose shorted turns in low voltage stator windings of 3-phase induction motors using LabVIEW. The diagnostic strategy is presented and variables that influence the diagnosis are discussed. Current spectra from motors with short-circuited turns (with and without short circuit current limiting ...

A new theorem on random walks suggest some possible revisions of the foundations of Quantum Mechanics. This is presented below in the simplified framework of the description of the evolution of a material point in space. Grossly speaking, it is shown that the probabilities generated by normalizing the square modulus of a sum of probability amplitudes, in the setup of Quantum Mechanics, becomes ...

At times in their interfirm relationships, distribution channel organizations may take advantage of their exchange partners by behaving guilefully. This opportunistic behavior adversely impacts channel member satisfaction (Gassenheimer et al., 1996) as well as the relational exchange norms among channel partners (Gundlach et al., 1995; Sindhav & Lusch, 2008). It also increases transaction costs...

We study a phase transition associated with the property of systolic freedom for families of metrics on 3-manifolds. Given a sequence of minimizing nonseparating surfaces in a systolically free sequence of metrics, we describe a certain accumulation phenomenon. The latter can be captured in the limit by a dichotomy property for the limiting minimal lamination. Such a dichotomy can thus be seen ...

In households surveys, quantities of interest are frequently elicited using categorized (range-card) formats rather than open-ended questions. One advantage of this format is that it typically reduces item non-response. Unfortunately, results from research in social psychology suggest that the choice of bracket values in range-card questions is likely to influence responses. Not much is known a...

This paper investigates the behavior of a vectorcontrolled, fault-tolerant, permanent magnet motor drive system adopting a vertically placed strip winding (VSW) which can limit inter-turn short-circuit (SC) fault current to its rated value regardless of the position in the slot containing the shorted turns. The drives’ dynamic behavior is simulated using a per-phase equivalent circuit model wit...

We present STAR’s measurements of directed flow for charged hadrons in Au+Au and Cu+Cu collisions at √ sNN = 200 GeV and 62.4 GeV, as a function of pseudorapidity, transverse momentum and centrality. We find that directed flow depends on the incident energy, but not on the system size. We extend the validity of limiting fragmentation hypothesis to different collision systems.
