tected, as it were, from another crossing over. This relation is illustrated in the diagram (fig. 7). If crossing over occurs at some point between two pairs of factors a and b indicated on the diagram, the next crossing over point of the chromosome would, if it occurred at all, lie at some distance away, rather than near by. This possibility can be tested in a case where several known points a...

We extend the definition of level-crossing ordering of stochastic processes, proposed by Irle andGani (2001), to the case in which the times to exceed levels are compared using an arbitrary stochastic order, and work, in particular, with integral stochastic orders closed for convolution. Using a sample-path approach, we establish level-crossing ordering results for the case in which the slower ...

Nonadiabatic electronic transitions between potential energy surfaces play a dominant role in many photoinduced chemical reactions, such as charge transfer, branching pathways in dissociation, and cis/trans isomerizations. Furthermore, nonadiabatic internal conversion (IC) to the ground state (S0) is believed to protect photoexcited natural chromophores (e.g. nucleic acid bases of DNA.) against...

Safety and security are the most discussed topics in the road and railway transportation field. Latest security initiatives in the field of railway transportation propose to implement video surveillance at level crossing(LC)environments. In this paper we explore the possibility of implementing a smart video surveillance security system that is tuned toward detecting and evaluating abnormal situ...

In part I (math.PR/0406392) we proved for an arbitrary onedimensional random walk with independent increments that the probability of crossing a level at a given time n is O(n). In higher dimensions we call a random walk ’polygonally recurrent’ (resp. transient) if a.s. infinitely many (resp. finitely many) of the straight lines between two consecutive sites hit a given bounded set. The above e...

In this article, the theoretically optimal prediction of level-crossings for a jump linear MIMO (multi-input multioutput) dynamical system driven by operator input is investigated. The study of this problem is motivated by the practical implications for design of an optimal alarm system as applied to the advance prediction of fuel flow overages, which will elicit the fewest false alarms for a f...

We fabricate a liquid-core liquid-clad microcavity that is coupled to a standard tapered fiber, and then experimentally map the whispering-gallery modes of this droplet resonator. The shape of our resonator is similar to a thin prolate spheroid, which makes space for many high-order transverse modes, suggesting that some of them will share the same resonance frequency. Indeed, we experimentally...

The recent sophistications in areas of mobile systems and sensor networks demand more and more processing resources. In order to maintain the system autonomy, energy saving is becoming one of the most difficult industrial challenges, in mobile computing. Most of efforts to achieve this goal are focused on improving the embedded systems design and the battery technology, but very few studies tar...

The spectral characteristics of multimedia signals typically vary with time. Preferably, the sampling density of them would comply with instantaneous bandwidth of signal. The paper discusses the level-crossing sampling principle, which provides such capability for analog-to-digital conversion. As the captured samples are spaced non-uniformly, the appropriate digital signal processing is require...
