The digital data in the form of CAD models can be obtained either from any advance CAD packages or scanned models from a 3D Scanner. Due to the extreme shortage of ventilators available in India and continues increase of corona virus patients’ day by day there is a need of more ventilators. Five percent of patients who are suffering from corona virus need ventilator support for breathing. To overcome the shortage of ventilators, ventilator splitters were developed and it can be shared by many patients for oxygen supply.It can able to control flow of oxygen from the ventilator splitters to different patient’s lung sizes. So in this research a ventilator splitter, design in CATIA software, Computational Fluid Dynamic (CFD) analysis was done using ANSYS16.0 and fabricated by process of Fused Deposition Modeling (FDM) using antimicrobial PLA material. Antimicrobial PLA is biodegradable plastic integrated with copper nano-particles, which will restrict the 3D printed parts contaminating bacteria’s. So, copper nano-particles PLA can be used for producing ventilator splitters for splitting oxygen to the four patients at a time emergency situation in hospitals. From the CFD analysis it is observed that the oxygen maximum static pressure (1.058e +002Pa) is at inlet of the ventilator and minimum static pressure (-2.17e+002Pa) at outlet of the ventilator splitters. The maximum oxygen flow velocity is 2.121e+001m/s and there is no change of temperature of the flow. It is also seen that net mass flow rate and net heat transfer rate are 0.0032676226kg/s and -0.051416769w respectively.","PeriodicalId":21797,"journal":{"name":"SEVENTH INTERNATIONAL SYMPOSIUM ON NEGATIVE IONS, BEAMS AND SOURCES (NIBS 2020)","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85358977","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}

Everything became easy, simpler, and can meet its aim speedy with web applications. These applications help to reach consumers, patrons, and stakeholders throughout the world easily. The web applications made it easier to keep a proper communication channel between business consortium and consumers. The web applications store the decisive information in its databases which it receives from users. The web application and database are accessible through the internet which gets affected by all the kinds of security threads, leads to misuse of the important information of the user by attackers. Among those attacks, the SQL Injection attack been placed under the top ten susceptibilities. By this type of attack, the hacker can steal important and confidential information from the database which will affect any business or consumer’s establishments. The paper here provides quintessential information on the functions of Machine learning, Predictive Analytics, and development of the consequential web that precisely calculates and avoids SQLIA with experiential valuation presented in the Receiver operating curve and Confusion matrix.","PeriodicalId":21797,"journal":{"name":"SEVENTH INTERNATIONAL SYMPOSIUM ON NEGATIVE IONS, BEAMS AND SOURCES (NIBS 2020)","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87282322","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 improve efficiency and prevent high heat loads on beamline components, permanent magnets are used to deflect co-extracted electrons out of the beam at a low energy. This field also affects the negative ions as they are accelerated, causing beamlets to exit the grid system with a residual offset and deflection angle. This adversely affects the overall divergence of the beam, and compensation is foreseen in future devices. Measurements of the residual deflection of a single beamlet have been carried out at the BATMAN Upgrade test facility by calculating relative beamlet angles from beam emission spectroscopy (BES) spectra, and through the use of one-dimensional carbon fibre composite (1D-CFC) tile calorimetry to find beamlet positions. It is described how these measurements can be made, and that they are limited to relative measurements only, for a single beamlet and for a single line of sight. The amount of beamlet deflection is shown to change significantly, by up to 0.6°(10 mrad), depending on the operational parameters used. As is to be expected the beamlet deflection angle is observed to be affected by changes to the voltages of the acceleration system. However, the beamlet deflection angle is also observed to change with RF power and other source parameters, which, to a first approximation, should only affect beamlet divergence, and not the deflection. These changes to beamlet deflection through parameters other than the grid voltages used may have consequences for systems planning to use suppression systems for the zig-zag deflection. The effectiveness of the suppression system may be reduced due to changes in the source parameters, which could lead to beam losses and high heat loads on downstream components.","PeriodicalId":21797,"journal":{"name":"SEVENTH INTERNATIONAL SYMPOSIUM ON NEGATIVE IONS, BEAMS AND SOURCES (NIBS 2020)","volume":"2 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83640772","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 meet this quick development in the construction exercises we are tremendously utilizing wide measure of sand and concrete. Because of this quick use of sand and concrete in huge sums, we are making normal unevenness. To kick sand we off mining of sand from waterway beds. which makes numerous characteristic dangers and become danger for people.
