Such resonators can be considered as a microwave system which contains diffusing and focusing portions and it may cause signs of wave chaos in the frequency resonator spectrum. Using the spectral approach we found the signs of wave chaos in the properties of the probability of the inter-frequency intervals distribution. When the cylinder resonator has regular side surface the spectral lines of the resonator are independent, and the probability of the inter-frequency intervals distribution similar to a Poisson distribution. In the case of existence of surface fractures or inhomogeneities, the spectral lines are correlated and the probability of the inter-frequency intervals distribution tends to the Wigner distribution.","PeriodicalId":333746,"journal":{"name":"2017 IEEE 37th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126711850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the H-case, the analysis uses the method of analytical regularization in the form of projection of the associated singular integral equation for the on-strip electric current to the set of Chebyshev polynomials, which invert the static part of the problem. In the E-case, the associated integral equation has only logarithmic singularity; we project it on the set of Legendre polynomials. As a result, in each case we obtain efficient numerical algorithm with guaranteed convergence. For arbitrary set of grating's parameters including the resonances, the accuracy of computations is controlled by the order of discretization. We study the dependences of the reflectance, transmittance, and absorbance by the graphene grating-in-slab scatterer on the strip width and frequency. We show that the strip width has effect only on the resonances on the surface-plasmon modes and does not influence the grating-mode and the slab-mode resonances in both polarizations.","PeriodicalId":333746,"journal":{"name":"2017 IEEE 37th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133410645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of disadvantages of this method is the low signal to noise ratio (SNR) and (or) contrast to noise ratio (CNR). That's why the image analysis tasks such as segmentation, reconstruction and registration are rather complicated. So the noise reduction in MR images is very important as a pre-processing task before going to image analysis. Furthermore, two dimensional (2D) imaging is incapable to provide a sufficient understanding of the complexity of the studied objects. So there is the necessity of having a 3D computer representation of many real objects. In this paper we are presenting the denoising and segmentation techniques developed for 3D MRI based on fractal and morphological approaches.","PeriodicalId":333746,"journal":{"name":"2017 IEEE 37th International Conference on Electronics and Nanotechnology (ELNANO)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130267964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
