By compares performance from sign language image files in the experiment, the results showed that the generation of the super-resolution image by improved Triangulation Interpolation technique can provide the best results when evaluating image performance using PSNR which has a similarity value between the original image and the high-resolution image. These use the PSNR method for measuring image quality. The PSNR value of sign language image is 40.6081 or has more efficiency at 13.15 percent when compared with the SRCNN techniques which are closest to the original image. For measuring performance by SSIM, which is a structured similarity measurement techniques, Triangulation Interpolation method can get the results of generating the super-resolution image next below the SRCNN technique.

The main idea is to optimize the degrees of freedom, which may be time, frequency, or both time and frequency, and are unoptimized in the conventional decode-and-forward relaying protocol. Without loss of generality, we focus on optimizing the time of relaying phases, namely, the source-to-relay phase, and the relay-to-destination phase. We proved that the proposed protocol always yield greater end-to-end instantaneous capacity than or equal to that of the conventional protocol, and also proved that the proposed protocol sometimes select the relay node, different from the relay node selected by the conventional protocol. The conventional and the proposed protocols are compared in terms of ergodic capacity and outage probability by computer simulations. The comparisons show that the proposed relaying protocol performs better than the conventional relaying protocol in all signal-to-noise ratio regimes.","PeriodicalId":404700,"journal":{"name":"2019 Research, Invention, and Innovation Congress (RI2C)","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122504783","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}

The scheme also considers variable turbine which rotates the generator at variable speed to generate variable AC voltage. The use of AC-DC-AC converter helps to convert the variable AC to DC and then to constant AC voltage and frequency. The design of control algorithms of the converter is based on the decoupled d-q control theory. The performance of the proposed scheme is analysed under resistive and inductive loads. The proposed model also has a D-STATCOM for regulating the output voltage at constant peak voltage during loading. The control principle of the D-STATCOM is based on a modified SRF theory and it has the ability to compensate unbalanced load current and load harmonics apart from regulating load voltage. The simulation is carried out with the help of MATLAB/Simulink and the power quality issues are also studied. The results show satisfactory performance of the proposed scheme.","PeriodicalId":404700,"journal":{"name":"2019 Research, Invention, and Innovation Congress (RI2C)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114839071","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}
