Parameter Mismatches and Perfect Anticipating Synchronization in bi-directionally coupled external cavity laser diodes
We study perfect chaos synchronization between two bi-directionally coupled
external cavity semiconductor lasers and demonstrate for the first time that
mismatches in laser photon decay rates can explain the experimentally observed
anticipating time in synchronization.Comment: Latex 4 page
Service innovation - lessons from modularization and open innovation - a new service value
The traditional manufacturing model of volume-variety influencing the conduct of business is not entirely representative of service-centric business. The latter has two key differences â it is much more end-user centric and individualistic in experience. The complex nature of service attributes also make it much more convoluted. The notion of product being the centre of interaction is being replaced with service processes involving participants and generally defined between a service provider and service consumer. The aim of this paper is to validate the service innovation hypotheses put forward based on significant developments in value networks, open interfaces, and business models recently. In doing so, this theoretical paper substantiates the claim that prescriptive volume-variety relationships are little meaningful in service delivery environment
Inverse Anticipating Synchronization
We report a new type of chaos synchronization:inverse anticipating
synchronization, where a time delay chaotic system can drive another system in
such a way that the driven system anticipates the driver by synchronizing with
its inverse future state. We extend the concept of inverse anticipating chaos
synchronization to cascaded systems. We propose means for the experimental
observation of inverse anticipating chaos synchronization in external cavity
lasers.Comment: LaTex 6 pages, resubmitted to PR
Lag time and parameter mismatches in synchronization of unidirectionally coupled chaotic external cavity semiconductor lasers
We report an analysis of synchronization between two unidirectionally coupled
chaotic external cavity master/slave semiconductor lasers with two
characteristic delay times, where the delay time in the coupling is different
from the delay time in the coupled systems themselves. We demonstrate for the
first time that parameter mismatches in photon decay rates for the master and
slave lasers can explain the experimental observation that the lag time is
equal to the coupling delay time.Comment: LaTex, 5 pages, submitted to PRE(R
Anticipated synchronization in coupled inertia ratchets with time-delayed feedback: a numerical study
We investigate anticipated synchronization between two periodically driven
deterministic, dissipative inertia ratchets that are able to exhibit directed
transport with a finite velocity. The two ratchets interact through an
unidirectional delay coupling: one is acting as a master system while the other
one represents the slave system. Each of the two dissipative deterministic
ratchets is driven externally by a common periodic force. The delay coupling
involves two parameters: the coupling strength and the (positive-valued) delay
time. We study the synchronization features for the unbounded, current carrying
trajectories of the master and the slave, respectively, for four different
strengths of the driving amplitude. These in turn characterize differing phase
space dynamics of the transporting ratchet dynamics: regular, intermittent and
a chaotic transport regime. We find that the slave ratchet can respond in
exactly the same way as the master will respond in the future, thereby
anticipating the nonlinear directed transport
Assessment of oceanic tuna and allied fish resources of the Indian exclusive economic zone based on exploratory surveys
The present paper overview the results of survey on marine resources
of the Indian EEZ including tuna and eillied fish species, their distribution, catch
rates, seasonality, assessment of stocks etc. supplemented by the chartered vessels'
data. The paper also presents the trends in the tuna fishing and future survey
