Transmission spectra of single ring coupled-waveguide resonator configuration by finite difference time domain method
Development of optical waveguide resonators have greatly expanded
and continues to grow since they have kinds potential applications such
as wavelength filtering, switching, coupling and multiplexing. One of
resonators, coupled waveguides, ring…

Prediction of rainfall using improved deep learning with particle swarm optimization
Rainfall is a natural factor that is very important for farmers or certain
institutions to predict the planting period of a plant. The problem is that rainfall is very difficult to predict. Trials to get optimal rainfall prediction have been carried…

Hidden Markov model technique for dynamic spectrum access
Dynamic spectrum access is a paradigm used to access the spectrum
dynamically. A hidden Markov model (HMM) is one in which you
observe a sequence of emissions, but do not know the sequence of states, the model went through to generate the…
