The 2PC protocol is further classified into linear and centralized versions. The linear version of 2PC i.e. L-2PC protocol runs serially whereas in the centralized version, the commit process allows every site involved in executing the transaction to prepare and commit in parallel. In past, very little efforts have been made to overcome the unfavourable message overhead, poor recovery process and some other problems associated with L-2PC protocol. This paper proposes a Linear and Fast-paced recovery centred Transaction commit (LIFT) protocol to improve the existing recovery mechanism of linear 2PC by allowing autonomy to the participating cohorts to inform the cohort-in-doubt about the distributed transaction’s state instead of always looking for coordinator’s stand. The performance results confirm that proposed protocol will be a better alternative.","PeriodicalId":195065,"journal":{"name":"Proceedings of ADCOM","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121034002","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}

Due to the characteristic property of NOMA to multiplex users in time, frequency and power domains, it can achieve capacity gains superior to OFDMA (orthogonal frequency division multiple access). However, being a multi-carrier modulation scheme, NOMA suffers from high peak to average power ratio (PAPR) in addition to the interference at the receiver terminal due to its non-orthogonal nature. In this paper we analyses the link level performance of 2x2 MIMO (Multiple Input Multiple Output) NOMA uplink system with Hadamard Transform Precoding (HTP) over Rayleigh fading channel model. The HTP NOMA enhances the PAPR performance by 3dB over the non precoded NOMA","PeriodicalId":195065,"journal":{"name":"Proceedings of ADCOM","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126035885","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}

Therefore, in this paper, we present a novel Bloom Filter, called accurate Bloom Filter (acBF), which features: a) an impressive guaranteed accuracy of 99.98%, b) a maximum false positive probability of 0.00015, c) lower collision probability, d) free from false negative, e) optimal insertion and membershipquerycost,andg)≤ 8−bits ofmemoryconsumption per item. acBF deploys eight multidimensional Bloom Filter.

We have conducted rigorous experiments to validate the accuracy of acBF which is unprecedentedly high. Also, acBF is compared with Scalable Bloom Filter (SBF) and Cuckoo Filter (CF). Experiments show acBF outperforms SBF and CF in terms of accuracy, and scalability. Moreover, performance of acBF outperforms CF in lookup operation. But, CF outperforms acBF in insertion. However, accuracy of acBF is incomparable with both SBF and CF.","PeriodicalId":195065,"journal":{"name":"Proceedings of ADCOM","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122797633","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 underlined concept in developing such a system is to build a human computer interaction. The interactions will be in natural language and we tend to use negation words as a part of our expressions. During the pre-processing stage in Natural Language Processing (NLP) task these negation words gets removed and hence the semantics gets changed. This remains to be an unsolved problem in QA system. In order to maintain the semantics we have proposed a novel approach Hybrid NLP based Bi-directional Long Short Term Memory (Bi-LSTM) with attention mechanism. It deals with the negation words and maintains the semantics of the sentence. We also focus on answering any factoid query (i.e. ’what’, ’when’, ’where’, ’who’) that is raised by the user. For this purpose, the use of attention mechanism with softmax activation function has obtained superior results that matches the question type and process the context information effectively. The experimental results are performed over the SQuAD dataset for reading comprehension and the Stanford Negation dataset is used to perform the negation in the RC sentence. The accuracy of the system over negation is obtained as 93.9% and over the QA system is 87%.","PeriodicalId":195065,"journal":{"name":"Proceedings of ADCOM","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133444199","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}

Millimeter Wave spectrum, massive Multiple Input Multiple Output (mMIMO), and Cloud Radio Access Network (C-RAN), are the key technologies which are expected to make 5G a reality. When massive MIMO is implemented in the context of C-RAN, the fronthaul capacity and the choice of functional split will limit the number of antennas that can be used. This effects the maximum achievable sum rate. In this paper, we estimate the maximum number of antennas that can be used at each functional split. Further, the optimal number of users that can be served at each functional split, with Zero-Forcing (ZF) & Maximum Ratio Transmission (MRT) beamforming techniques is also investigated. It is observed that, split option 1 supports the maximum number of antennas, and serves the maximum number of users.","PeriodicalId":195065,"journal":{"name":"Proceedings of ADCOM","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133224960","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}
