Computer use is becoming part of our lives every other day however there have been considerable threats of computer viruses in the recent past. Viruses have had adverse effects on data and programs ranging from formatting hard disks, damaging information infrastructure, suddenly restarting machines, deleting or modifying data and in some cases mild effects such as slowing down machines or producing irritating sounds. Viruses have been a major cause for worry especially with the advances in data processing, storage and movement of information technologically. Many computer users and organizations especially the computer intensive organizations have had to invest heavily in dealing with viruses particularly those organizations running the windows platform. These computer viruses have been defined by their characteristics of entry and multiplication without the user’s notice as well as diverting the normal functioning of the computer. This paper seeks to define a virus and explain its related terms such as malicious software, worms, and Trojan horses. It explains vulnerabilities of operating systems in relation to viruses, it makes an observation on strengths of Linux versus Windows, outline the present state of affairs, apart from using anti-virus software, there are other procedures which can help protect against viruses which are also mentioned, the future of computer viruses and the conclusion that the Internet is serving its purpose of interconnecting computer and hence promoting distribution of viruses then makes some recommendations on viruses.
The outrage of the COVID-19 has hit the healthcare industry tremendously. This pandemic has created a huge demand for necessary medical equipment, medicines, advanced requirement robots, and artificial intelligence-based applications. Intelligent robots have great potential to provide diagnostic risk assessment, monitoring, telehealth, disinfection, and other services other operations. The long-awaited vaccine discovery of this virus has also been greatly accelerated by the AI-enabled tool. Also, many robotic and Robotic Process Automation platforms have greatly facilitated the distribution of the vaccine. cutting edges technology have also helped brings comfort to people facing less addressed health complication. This paper investigates the use of robotics and artificial intelligence-based technology and their applications in healthcare to fight against the COVID-19 pandemic.
The economy of our country heavily depends on agrarian produce. This is the driving force behind Recognizing unhealthy leaves is the key to preventing crops from declining and yield from declining. It required a tremendous amount of labour, knowledge of the leaf diseases, and a tremendous lot of time. As a result, methods for image processing are used to find and identify unhealthy plant leaf conditions. Automatically identifying plant leaf diseases is helpful because it reduces the laborious task of observing in large farms and identifies disease symptoms right away. The stages of image acquisition, image pre-processing, picture segmentation, feature extraction, and classification are involved in the detection and identification of plant leaf diseases. The methodologies for pre-processing images, picture segmentation algorithms for automatic recognition, and research on potential plant leaf disease classification algorithms are all included in this work.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
