Blocks consisting the boundary of moving object need more bit for better prediction of the current frame because real-world objects are not block-based and their motion is not translational. One of the main goal of the current standard (HEVC) is to minimize the prediction error energy by using quad-tree splitting method. But if motion discontinuity exits, quad-tree based splitting method uses a large amount of motion bit-rate and also introduces a potential coding overhead in the video encoder and decoder. In this paper, we propose a segmentation-based method of using arbitrary shape superpixel and affine motion registration technique for reducing the prediction error energy between the current and reference frame. This method uses the already encoded reference frame for predicting the current frame. The experimental result shows that good subjective quality with PSNR up to 27.71dB can be obtained using this approach.","PeriodicalId":138634,"journal":{"name":"2019 5th International Conference on Advances in Electrical Engineering (ICAEE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116933040","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}

We have computed the threshold exciton density and also the variation of output photon flux density with the changes of input current density for different coupling factors. To explore the high frequency performance of TMD exciton lasers, we have reported high frequency modulation response of the exciton lasers considered in this study. To have a better comparative insight into the high frequency performance of these lasers, we have also calculated intrinsic and -3dB bandwidth, modulation efficiency and differential gain of $WS_{2}, {WSe}_{2}$ and ${MoTe}_{2}$ excitonic lasers. The high bandwidth for TMD exciton lasers found in this present study denotes the potential excellance of using these lasers in high frequency optical communication applications.

In this paper, we aim to identify additional risk factors and observe factors identified in various studies related to maternal mortality rate in Bangladesh, using a different data repository- The World Bank data repository which is based on World Development Indicator (WDI), 2015. Taking the significant factors into account, we build multiple stepwise linear regression models as base models and evaluate model performances using MAE, RAE and RMSE under the shed of k-fold cross validation.

Previously, some statistics based feature selection techniques have been used to identify the DEGs and DEMs. It is not up to the mark. More research work and investigation are required in this area. In this paper, we have used Student’s T-test with Hochberg P adjustment to identify the DEGs and DEMs. We have also distinguished the down-regulated and up-regulated genes using the logarithm of the fold change value and Heatmap plot.

But, one of the many limitations in LR-PON is the grant of excess bandwidth to the optical network units (ONUs) that they don’t even need which is globally known as “Over-granting” problem. The traditional multi-thread polling (MTP) algorithm is unaware of the fact that, the lack of frame fragmentation is prone to the over-granting problem which eventually leads to degradation in the overall delay incurred to the system. Existing enhanced-IPACT (E-IPACT) scheme claims to solve the problem but has some inefficiency. In this very paper, we come up with a new online-based MTP scheme named sorted frame multi thread polling (SF-MTP) where we propose an arrangement of all the frames in order to improve the quality of services (QoSs). Also, wehave presented an effective solution to the reporting of the unreported frames from the previous dynamic bandwidth allocation process. In SF-MTP, ONUs’ are considered to have ability to take necessary decisions. After evaluating the performance by simulations, it implies that the SF-MTP scheme is more economical than other parallel schemes with respect to some QoS parameters.","PeriodicalId":138634,"journal":{"name":"2019 5th International Conference on Advances in Electrical Engineering (ICAEE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125249905","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}
