The antenna comprises a semi-circular disc magnetic dipole and a directive open loop antenna, etched on a two-layer substrate. By choosing appropriate element shapes and separation distances the required characteristics for the generation of circular polarization are achieved. The proposed microstrip antenna is numerically simulated, and a prototype is developed for experimental validation. The antenna resonates at 2.4 GHz and exhibits measured impedance and axial ratio bandwidth of 12.5% and 13.7% respectively. The azimuth and elevation axial ratio beam widths are 89° and 118° correspondingly. The proposed antenna would be a very promising alternative for RFID applications.","PeriodicalId":106004,"journal":{"name":"2021 IEEE 18th India Council International Conference (INDICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130115003","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}

To repair these faulty memory cells, redundancies are included in the memory in the form of spare rows and columns. The process of mapping faulty lines to redundant cells is Redundancy Analysis. Applying a uniform Redundancy Analysis algorithm on the wafers or running algorithms sequentially one after the other would either compromise on the repair time or wafer yield. An end-to-end solution for memory repair is proposed in this paper. A clustering algorithm to classify, identify and extract features from chip errors on a wafer is proposed. These features along with other derived parameters are used as an input to the neural network recommender system to select algorithms allowing an increase in the wafer yield keeping a low repair time per wafer. We have performed comparisons of the generated result with and without clustering and with other methods of classification of chips for Redundancy Analysis algorithm selection such as Decision Trees. Experimental results demonstrate that this solution out-performs the heuristic algorithmic solutions by 9.1% and 32.9% in terms of yield for medium and high error rates.","PeriodicalId":106004,"journal":{"name":"2021 IEEE 18th India Council International Conference (INDICON)","volume":"371 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132399536","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}

Identifying the type of tumour from the histopathological images is a difficult task for the pathologist. In this work, a deep learning based osteosarcoma classification algorithm using ensemble approach and fusion approach is proposed. Multilevel features are extracted from a pre-trained EfficientNets trained on imagenet1k dataset. EfficientNets are scaled convolutional neural networks. This scaling is done in depth, resolution and width. Features are extracted from the initial layers, intermediate layers and final layers of a selected EfficientNet. In general, they represent the low frequency, middle and high frequency details of the images. Independently, the features are given to an error control output coding classifier with support vector machine as base learner. Ensemble prediction is done on the test images by using majority voting from the models trained using features extracted at various levels from EfficientNet. Further, a fused feature vector is formulated from the selected layers of EfficientNets and given to the error control coding output classifier. The proposed algorithm with ensemble approach and fusion approach offers higher mean and peak classification accuracy compared to the existing works in the literature.","PeriodicalId":106004,"journal":{"name":"2021 IEEE 18th India Council International Conference (INDICON)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123368318","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}

As frequent PAF events may easily lead to serious heart conditions, such as stroke, arterial embolism, it is propitious to have an early warning system. To this end, we propose an automated system for early prediction of PAF events based on statistical and nonlinear features extracted from heart rate variability (HRV) signal. We compute multiscale symbolic entropy, visibility graph-based complexity measures and three time-domain measures from the HRV signal. Out of them, the independent discriminative features are selected by Wilcoxon signed-rank test and correlation assessment. Finally, the selected features are applied to support vector machine (SVM), naive Bayes, and logistic regression classifiers to obtain the best prediction model. We achieve the best prediction results using radial basis function based SVM classifier with sensitivity, specificity and accuracy of 96.15%, 97.06%, 96.80% respectively, from the segments 5-10 mins before the onset of PAF events.","PeriodicalId":106004,"journal":{"name":"2021 IEEE 18th India Council International Conference (INDICON)","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121084123","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}
