Reuse of resource blocks (RBs) in D2D links creates interference to cellular users (CUs) and the interference becomes severe when D2D transmitters and receivers are connected with different cells. However, minimization of both intracell and inter-cell interference is a challenging task while realizing intercell D2D communication. In this paper, we propose a resource allocation scheme, named CoRAL, where the neighbor base stations (BSs) coordinate between themselves to minimize the interference caused by the D2D communication. Each base station computes a look-up table (L UT), comprising the degradation in throughput for each RB. The coordination between the serving BS (S-eNB) and its neighbor BSs (N-eNBs) is obtained by sharing the LUTs. The S-eNB combines all the LUTs and forms an updated table, which is used for the resource allocation algorithm. We formulate the resource allocation problem as a minimization problem of the degradation of achieved throughput due to sharing of RBs between D2D users and CUs in the system. CoRAL enhances the system throughput by minimizing the intra and intercell interference simultaneously in the presence of D2D communication. It uses an iterative approach for allocating RBs to D2D users. The simulation results show that CoRAL outperforms the uncoordinated resource allocation techniques where a single base station decides the resource assignment procedure and a popular scheme GALLERY from existing literature.","PeriodicalId":403870,"journal":{"name":"2022 National Conference on Communications (NCC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114043156","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 synthesized speech should align with the events in the source video to have a realistic experience. Most of the existing prosodic alignment processes operate on the synthesized speech by controlling the speaking rate. In this paper, we propose subtitle synthesis, a unified approach for the prosodic alignment that operates at the feature level. Modifying the prosodic parameters at the feature level will not degrade the naturalness of the synthesized speech. We use both inter and intra utterance alignment in the prosodic alignment process. We should have control over the duration of the phonemes to perform alignment at the feature level to achieve synchronization between the synthesized and the source speech. So, we use the Prosody-TTS system to synthesize the speech, which has the provision to control the duration of phonemes and fundamental frequency (f0) during the synthesis. The subjective evaluation of the translated audiovisual content (lecture videos) resulted in a mean opinion score (MOS) of 4.104 that indicates the effectiveness of the proposed prosodic alignment process.","PeriodicalId":403870,"journal":{"name":"2022 National Conference on Communications (NCC)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122290152","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}

There are various methods proposed in literature for providing privacy to speech data. Previous works that have been done to protect the speaker identity were done for speech applications like automatic speech recognition (ASR), speech analysis, etc. For these applications the presence of speaker identity is not essential while processing. The objective of this work is to provide privacy to the task in which presence of speaker identity is essential at the time of processing. In this work, privacy is provided to the speaker identity information present in speech signals while performing automatic speaker verification (ASV) tasks. In order to achieve the same, this work proposes a prosody modification based approach. The proposed approach is able to conceal the speaker identity from human perception by changing the pitch of the speech utterances with a pitch modification factor of $alphageq 1$ But at the same time the ASV system provides consistent performance irrespective of the change in pitch (i.e. for $alphageq 1)$. The same evidence has been shown through experiments in TIMIT and IITG-MV databases. A subjective study has also performed to verify the extent of speaker anonymization with respect to humans. The subjective study evaluates the performance in terms of mean opinion score (MOS). The observed MOS signifies the ability of the proposed approach to conceal the speaker's identity.","PeriodicalId":403870,"journal":{"name":"2022 National Conference on Communications (NCC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128772993","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}

Existing microwave antenna designs for ablation are around 2 mm and above in outer diameter which requires a greater hole size in the human body for the insertion of the applicator into the site of tumor. In this paper, we propose miniaturized coaxial slot antennas with an outer diameter of 1 mm which satisfies the medical requirement to minimize the invasiveness. Two types of miniaturized antennas namely monopole with slot and dual slot with an outer diameter of 1 mm are designed and simulated in CST at two different frequencies (915 MHz and 2.45 GHz) to determine the variation in the characteristics of both antennas w.r.t. frequency. Return Loss, Voltage Standing Wave Ratio (VSWR) and Specific Absorption Rate (SAR) pattern of antennas are analyzed to determine the efficiency of the antenna, heating pattern and ablation zone. Simulation results indicate that a dual slot antenna has uniform power distribution around the region of tumor, minimum backward heating and better sphericity in ablation pattern compared to a monopole slot antenna. Also, the antennas operated at 2.45 G Hz are more suitable for creating rapid spherical ablation with a larger diameter compared to the antennas operated at 915 MHz. So we can conclude that a dual slot antenna operated at 2.45 GHz is best suited for microwave ablation.","PeriodicalId":403870,"journal":{"name":"2022 National Conference on Communications (NCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129886212","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}

Cytopathologists typically consider a low-resolution image to identify the malignant regions. The identified regions are scanned at a higher resolution to confirm malignancy by investigating the cell level behaviour. Scanning and processing time can be saved by zooming only the identified malignant regions instead of entire low-resolution images. This work predicts malignancy in cytology images at a very low resolution (4X). Annotation of cytology images at a very low resolution is challenging due to the blurring of features such as nuclei and texture. We address this issue by upsampling the very low-resolution images using adversarial training. This work develops a semantic segmentation model trained on 10X images and reuse the network to utilize the 4X images. The prediction results of low resolution images improved by 15% in average F-score for adversarial based upsampling compared to a bicubic filter. The high resolution model gives a 95% average F-score for high resolution images. Also, the sub-area of the whole slide that requires to be scanned at high magnification is reduced by approximately 61% while using adversarial based upsampling compared to a bicubic filter.","PeriodicalId":403870,"journal":{"name":"2022 National Conference on Communications (NCC)","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122831325","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}

Earlier works relies on hand-crafted features, which hardly represents the temporal dynamics. Later, video representations learned through supervised deep learning methods were found to be effective, but at the cost of large labeled dataset. Recently, self-supervised based methods for video representation learning are proposed within the community to harness the freely available unlabeled videos. However, most of these methods are based on single pretext task, which limits the learning of generalizable representations. This work proposes to leverage multiple pretext tasks to enhance video representation learning and generalizability. We jointly optimized the C3D network by using multiple pretext tasks such as: rotation prediction, speed prediction, time direction prediction and instance discrimination. The nearest neighbour task is used to analyze the learned features. And for action recognition task, the network is further fine-tuned with pretrained weights. We use the UCF-101 dataset for the experiments and, achieves 28.45% retrieval accuracy (Recall@l), and 68.85% fine-tuned action recognition accuracy, which is better than state-of-the-arts.","PeriodicalId":403870,"journal":{"name":"2022 National Conference on Communications (NCC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130638377","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}
