Social interactions vary in time and appear to be driven by intrinsic mechanisms, which in turn shape the emerging structure of the social network. Large-scale empirical observations of social interaction structure have become possible only recently, and modelling their dynamics is an actual challenge. Here we propose a temporal network model which builds on the framework of activitydriven time...

Microstructural examination can provide a rich tapestry of information about the processing and application history of a metal component. For this reason, microstructural characterization is a fundamental tool for failure analysis of these components. To reduce costs and accommodate demands for smaller packaging, many applications currently use metallic components where the critical dimensions ...

nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. common techniques applied for harmonics measurement and assessment such as fft have significant errors in presen...

evolving models have found applications in many real world systems. in this paper, potentials of the evolving linear models (elms) in tracking control design for nonlinear variable structure systems are introduced. at first, an elm is introduced as a dynamic single input, single output (siso) linear model whose parameters as well as dynamic orders of input and output signals can change through ...

this paper proposes a new method of gain scheduling control design for a nonlinear system which is described as linear parameter varying form. a performance measure based on linear matrix inequality is introduced. to consider stability and performance measures in design process, the h∞ loop-shaping method is used to design the local controllers, which can be described as state feedback observer...

in this paper the numerical analysis of flow and time dependent heat transfer of micro-tube conveying nanofluid in laminar flow is investigated. in this study, convection heat transfer of nanofluid and base fluid and transient analysis for time-varying heat flux for time step of 0.0001 second are elucidated. it is observed that the pumping power of nanofluid flowing and the maximum temperature ...

Ahstrucf -We consider the capacity of an arbitrarily varying channel (AVC) for deterministic codes with the average probability of error critenon and, typically, subject to a state constraint. First, sufficient conditions are provided that enable (relatively) simple decoding rules such as typicality, maximum mutual information, and minimum distance, to attain capacity. Then the (possibly noisy)...

This research was inspired by the need to increase the flexiblity and cost efficiency of a face recognition system by utilizing wireless sensor network for data transmission. Swarm intelligence is used to optimize routing in distributed time varying network by maintaining the required bit error rate for varied channel conditions while consuming minimal energy. Simulation shows the energy effici...
