Wallace tree encoder is an effective hardware implementation in VLSI circuits that is utilized for the analogue to digital conversion process. The Wallace tree encoder transforms thermometer code into binary code in an ADC. The suggested flash digital to analogue converter confirmed the energy, and speed. The proposed technique provides Less Delay, Less Power Consumption, and a lesser number of transistors compared to existing techniques. In this project, the proposed transmission gate full adder technique provide Less Delay, Less Power Consumption, Better Power Delay Product and a lesser number of transistors. The proposed encoder is made to count the 1s available to the logic gates for designing ROM encoders and fat tree conversion. The power may be conserved by building a low power, high performance Wallace tree encoder implementing transmission gate logic and modified full adders since Wallace tree encoder uses more power. The proposed system focuses at lowering the transistor count to improve power efficiency and delay comparator, and it is effective in minimizing the bubble errors. The Wallace tree encoder is designed by using transmission gate based full adder circuits. The proposed designs are designed and simulated using LTspice Tool with 45nm CMOS technology. The power consumption of the encoder circuit must be decreased in order to create a low power Flash ADC. The power consumption of this encoder changes noticeably when the internal full adder circuit is modified","PeriodicalId":13964,"journal":{"name":"International Journal of Emerging Trends in Engineering Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47752825","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 the ongoing work, a novel geopolymer concrete (FGPC) that was modified with polypropylene fibres been created as a replacement to conventional cement concrete. FT-IR, XRD, SEM, and the BET adsorption-desorption isotherm model were employed to evaluate the nanoproperties of the geopolymer concrete modified with polypropylene fibre.

The telecommunications industry handles tonnes of essential, personal and sensitive data on staff, clients and customers. This data is critical in developing product lines and marketing strategies for telecom companies, opening them up to opportunities that otherwise would have been beyond their reach. As a result, telecom companies’ databases are rendered vulnerable to violation and unauthorised access from insiders, third-party entities, as well as hackers. They have become premium target for cyberattacks, malware, interference, data theft and loss of vital data. While systems for the management of data in the telecom industry are crucial in gathering, storing, and analysing data, it is equally important for such systems to be efficient enough to provide a safe and secure mode of accessing, analysing and storing data assets. This is to prevent illegitimate use of sensitive data, cyberattacks, malware and data infringements on telecom data assets.","PeriodicalId":13964,"journal":{"name":"International Journal of Emerging Trends in Engineering Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42457442","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}
