Light emitters in the vicinity of a hyperbolic metamaterial (HMM) show range quantum optical phenomena from spontaneous decay-rate enhancement to strong coupling. In this study, we integrate monolayer molybdenum disulfide (${\mathrm{Mo}\mathrm{S}}_{2}$) emitter near-field region HMM. The ${\mathrm{Mo}\mathrm{S}}_{2}$ has $A$ and $B$ excitons, which emit red visible spectrum. We find that excito...

In this paper, a new Hidden Markov Model (HMM)-based face recognition system is proposed. As a novel point despite of five-state HMM used in pervious researches, we used 7-state HMM to cover more details. Indeed we add two new face regions, eyebrows and chin, to the model. As another novel point, we used a small number of quantized Singular Values Decomposition (SVD) coefficients as feature...

Passive acoustic monitoring (PAM) is generally usedto extract signals produced by cetaceans. However, the large data volume from PAM process better analyzed using an automated technique such as hidden Markovmodels (HMM). In this paper, HMM used a detection and classification due to its robustness low time complexity. Nonetheless, certain parameters, choice of features be extracted signal, frame...

Oil and gas pipeline leakages lead to not only enormous economic loss but also environmental disasters. How detect the damages including cracks has attracted much research attention. One of promising leakage detection method is use zirconate titanate (PZT) transducers negative pressure wave when occurs. PZT can generate guided stress waves for crack also. However, or may be easily detected with...

Abstract In this paper, we consider separating the discretisation of diffusive and advective fluxes in complete flux scheme. This allows combination several methods for homogeneous with (CF) method. particular, explore hybrid mimetic mixed (HMM) method CF method, order to utilise advantages each these methods. The usage HMM us handle anisotropic diffusion tensors on generic polygonal (polytopal...

speaker verification from talking a few words of sentences has many applications. many methods as dtw, hmm, vq and mq can be used for speaker verification. we applied mq for its precise, reliable and robust performance with computational simplicity. we also used pitch frequency and log gain contour for further improvement of the system performance.
