The aim of the smart level crossing project is to improve the safety of rail and road systems without compromising the regularity of trains. The LC must become interactive with its environment by integrating new communication technologies with the train and road users.

We discuss the behavior of two coupled optical modes, specializing to the case of a clockwise and a counter-clockwise wave in an optical ring with backscattering. Generally the coupling constant is complex-valued; the limiting cases of conservative and dissipative coupling are emphasized.

Antiadiabatic theorem for crossing levels
Physical Review Letters, 1989We consider in this note the time dependence of a system for which two levels (which are not in general decoupled) accidentally cross (or almost cross) for some value of the parameters of the Hamiltonian. We show that for a well-defined class of crossings or narrowly avoided crossings, in which the Hamiltonian changes slowly on its own scale, the ...

Living systems: Cross-level hypotheses
Behavioral Science, 1965The preceding article considered salient characteristics of the subsystem and system-wide processes which generally occur at all levels of living systems. Using the concepts developed in that article, the present exposition states 165 hypotheses that may be applicable to two or more levels of living systems. Some are original with the author. Some have

This chapter describes a basic level crossing estimation method (LCE) for steady-state (i.e., limiting) probability distributions in queues, storage processes and related stochastic models. LCE is also called: level crossing computation, system point estimation (or computation).

Abstract This chapter introduces normative externalism about epistemology. It takes what is central to normative externalism to be the denial of level-crossing principles. A level-crossing principle says there is a necessary connection between the propriety of a belief (in some sense of propriety), and the propriety of believing that ...

Cross‐Level/Ecological Inference
2009AbstractThis article reports the main methodological approaches to the statistical problem. It describes the fundamental indeterminacy of the problem. It also provides a framework that coherently binds the variety of approaches that have been proposed to address this problem.

Molecular Level-Crossing Spectroscopy
The Journal of Chemical Physics, 1966Classical and quantum formulations are presented for the effects of level crossings on the angular distribution of molecular resonance fluorescence. It is shown that a study of the ``molecular Hanle effect,'' or its electric-field analog, may be used to determine the product of the radiative lifetime ρv′J′ with the magnetic moment μm, or the electric ...
