Attributed to the single bitline structure, the proposed cell consumes smaller power and the presence of stacked NMOS and PMOS transistors in the design enables it to sustain higher value of charge deposition at its sensitive nodes. RH13T cell offers better critical charge, stability and power dissipation, at the cost of delay penalty, than the cells considered for comparison in this work. We use HSPICE simulations with 65nm PTM model for the analysis and comparison of SRAM cells. The proposed RH13T cell demonstrates critical charge that is 69.64%, 2.64% and 1.82% higher and Hold Static Noise Margin (HSNM) which is 142%, 20% and 19.766% higher than the conventional 6T, AS8T and AS10T SRAM cells respectively. We observe that RH13T offers reduction in write power of 74.72%, 77.23% and 78.408% and reduction in read power of 12.66%, 13.103% and 41.128% and reduction in leakage power of 18.51%, 23.23% and 32.36% when compared to conventional 6T, AS8T and AS10T SRAM cells respectively.

The people with DM are all susceptible to acquiring diabetic retinopathy (DR). Microaneurysms, haemorrhages, and exudates are the early symptoms of DR that manifest on the surface of the retina. This paper proposes a deep learning (DL) method based on non-clinical features for grading DR in retinal fundus images. The method is based on ensampling multiple DL networks. The multi-network architecture is well suited to represent the fundus image’s features properly. The proposed model consists of three well-known DL models, mainly VGG16, DenseNet121, ResNet50. For each network, a classifier network grades DR into five classes (i.e., No DR, Mild, Moderate, Severe, and Proliferative). A maximum voting algorithm is applied to merge the three probabilities resulting from the three classifiers to achieve the final DR grading. The proposed system is assessed using the public DDR dataset. The experimental results show that the proposed method based on voting with the DenseNet121 and VGG16, and ResNet50 outperforms the state-of-the-art.","PeriodicalId":300301,"journal":{"name":"2022 5th International Conference on Multimedia, Signal Processing and Communication Technologies (IMPACT)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134293280","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 antenna is imprinted on Duriod substrate with the relative permittivity of 2.2. It possesses incredible flexibility and is highly resistant to thermal shocks. The fractal design has 6 iterations, consisting of rectangular and circular fractals and operates in the sub-6 GHz band (3.4 GHz to 6 GHz) and low (under 1 GHz) frequency bands. The antenna and the breast phantom are designed in HFSS software. The breast phantom is comprised of 3 layers (fat, fibro and skin) and the tumor has different physical and electro-magnetic properties parameters. The breast phantom with and without tumor exhibits a noticeable difference in the results for S11, S21, gain, and radiation pattern, underlining the tumour’s presence and making its detection possible.","PeriodicalId":300301,"journal":{"name":"2022 5th International Conference on Multimedia, Signal Processing and Communication Technologies (IMPACT)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132450848","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}

In this scenario, the need to ensure the basic security requirements of Confidentiality, Integrity, and Availability is an important task. To analyze the security requirements penetration testing is being done. The process of manual penetration testing is slowly shifting towards automated testing systems. Security experts are designing automation tools to detect vulnerabilities. This paper deals with binding the known multiple vulnerabilities to find the overall vulnerability of a web application. The impact of the vulnerability is analyzed by combining multiple penetration testing tools which automatically classify the exploit model to gather information using the signature patterns (Regular Expressions). Finally, the exploit information can be viewed in the form of a report so that security patches of the vulnerabilities can be performed.","PeriodicalId":300301,"journal":{"name":"2022 5th International Conference on Multimedia, Signal Processing and Communication Technologies (IMPACT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130553378","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}

Incorporating the Capsule design into the Discriminator will improve the classification loss and speed up the convergence compared to using traditional convolutions. With 188 hand-drawn sketch-photo pairings available in the CUHK dataset and constructed 1000 sketch-photo pairs of CelebA HQ dataset, our proposed method is evaluated.
