As computing systems become increasingly complex and diverse, traditional static scheduling algorithms often struggle to adapt efficiently to the dynamic nature of workloads. DPAS addresses this challenge by introducing a dynamic and adaptive approach to process prioritization and resource allocation. DPAS leverages real-time feedback, machine learning, and resource awareness to assign and adjust priorities for running processes. Unlike conventional schedulers with fixed priority schemes, DPAS continuously evaluates process behavior and resource utilization, making real-time adjustments to process priorities. This adaptability ensures that critical processes receive the necessary attention while preventing resource monopolization by any single task. Furthermore, DPAS incorporates adaptive time quantum allocation, energy-efficient scheduling, and security measures to strike a balance between responsiveness, energy conservation, and system security. It utilizes process grouping and tagging to accommodate different workload characteristics and requirements, enhancing both fairness and system efficiency. The DPAS algorithm represents a significant advancement in CPU scheduling, offering improved system responsiveness, resource management, and adaptability to diverse workloads.

It is speedy, easy to use, and can smoothly alter data with no hiccups. It aids in the processes of data analytics generally, such as data collection, analysis, modelling, and visualization. Python stands out from other languages because it provides all the necessary tools for developing cutting-edge applications and machine learning quickly and easily. The fields of data science and analytics have benefited greatly from recent advances in computing power, the capacity to store vast volumes of data, and knowledge of relevant methodologies in areas such as Data Analytics, Artificial Intelligence, Machine Learning, etc. The goal of this study is to have a discussion on the. All the fundamental resources for developing Python applications may be found in a single place with the help of an IDE (Integrated Development Environment). Integrated development environments (IDEs) are research-oriented software packages that bring together a familiar Graphical User Interface (GUI) with the most widely used programming languages and tools. It often consists of a source code editor for writing programs and local build automation for creating a local version of the software, like compiling computer source code. Additionally, it enables you to duplicate the programs for use on your personal computer. These editors may be used by developers and software engineers to design apps for personal computers or the web; by DevOps engineers to carry out continuous integration; and to aid in job automation and boost the software engineer's productivity and expertise. Some of the many great advantages of adopting a top-tier Python integrated development environment are listed below. Build automation, code linking, testing, and debugging are just some of the features available in Python IDEs that may help you save time.

However, attacks like Distributed Denial of Service (DDOS) attacks can still affect these simulated networks. A CIC flowmeter can be used to monitor network traffic and Wireshark can be used to record and analyse network data in real-time to detect and analyse such assaults. However, the data obtained from these tools may be noisy, which can negatively impact the accuracy of attack detection and analysis. To address this issue, machine learning algorithms can be applied to clean the data obtained from CIC flowmeter and Wireshark. In this study, we propose an approach that uses Mininet-WiFi in combination with a CIC flowmeter, Wireshark, and machine learning algorithms for data cleaning to detect and analyse DDOS attacks in a virtual wireless network. We will discuss the setup and configuration of Mininet-WiFi, CIC flowmeter, and Wireshark, and demonstrate how machine learning algorithms can be used to clean the data obtained from these tools to improve the accuracy of attack detection and analysis.</p> 2023-06-22T00:00:00+00:00 Copyright (c) 2023 JOURNAL OF OPERATING SYSTEMS DEVELOPMENT & TRENDS https://stmcomputers.stmjournals.com/index.php/JoOSDT/article/view/544 Identification of Handwritten Digits using Machine Learning 2023-06-06T10:50:10+00:00 Devansh Gera [email protected] Yash Popli [email protected] Gungun Singhal [email protected] Komal Mittal [email protected] Reena Sharma [email protected] <p>Handwritten Digit Recognition is one of the practical issues in sample recognition applications.

There is no certainty that we would get our files back even after paying the ransom amount. Since these ransomware attacks are increasing day by day and are causing heavy losses to people, we have proposed a new backup based ransomware defense system along with a feature of malicious files scanning. This software works on the principle of automatic backup and detects the newly added files in the system in realtime and instantly back ups them in the destination folder, which is embedded into a Solid State Drive (SSD). The software itself also resides in the SSD drive because being separated from the host machine provides better data protection than the softwares which are inside the machines as they are vulnerable to ransomware attack, this also helps it to operate in various environments. The software provides several options to the user which includes, simple PC backup, android backup, automatic backup, as well as cryptic backup.

The user needs to join with Twilio using join and the sandbox name keyword and then user gets connected to the Chatbot system. The Python software will then read the user's request to enter the chatbot, and if the incoming message satisfies the criteria, the chatbot will send the information in accordance with the criterion. However, Chatbot will still go through the motions of reading incoming messages if it does not match. The Chatbot technology is made to work well with numerous users at once. The chatbot server connection affects how quickly messages are sent and how quickly each incoming message is checked.

This makes smartphones a top target for cyberattacks, as either the loss of such mobile devices or unauthorised access will result in a breach of personal data and financial harm. Over the past few years, a number of new types of authentication systems have been presented in an effort to allay that worry. One of those classes is Graphical Authentication (GA), which is the subject of this study. Due to their primarily graphics-oriented nature, superior memorability versus text-based schemes, and lack of additional hardware requirements, GA schemes are more well-liked and preferred for smart devices. The majority of these GA systems are vulnerable to many well-known attacks, including brute force, shoulder surfing, and smudging. As a result, a novel hybrid authentication scheme, Passpoints and Press Touch Code, or PTC, that smoothly combines two distinct yet widely used authentication techniques is proposed in this work.

E-mails are the most commonly used form of communication in today's business. These are now the most convenient modes of communication for most people. We will also look into adding confidentiality and integrity protection to standard email. In your daily life, how much reliance do you place on the accuracy of its contents? Consider receiving an e-mail from your mentor stating that you performed so well in your course that you were excused from doing any additional work. What if you know that message was a joke from a classmate? For sensitive information or communication, we always rely on e-confidentiality mails and integrity. The email client is a critical network application. It is significant when it is used to communicate vital information such as business data, patient medical records, and so on by business, health, and educational groups.

Email has become a popular choice for official communications in many businesses due to its numerous features. Electronic mail is widely used for personal purposes and is accessible via a variety of suitable software clients as well as a web browser. Email security has become a critical concern for the information security research community in order to improve email security. The developed application with three layers of authentication provides enhanced security for critical emails shared over the Internet and eliminates the risk of the message being hacked.</p> 2022-12-29T00:00:00+00:00 Copyright (c) 2022 JOURNAL OF OPERATING SYSTEMS DEVELOPMENT & TRENDS https://stmcomputers.stmjournals.com/index.php/JoOSDT/article/view/390 Handwritten Digit Recognition Using Logistic Regression, SVM, KNN and CNN Algorithms 2022-12-19T05:52:46+00:00 K.

Quantum cryptography is the science of performing cryptographic operations using quantum mechanics principles. Quantum key distribution is the most well-known example of quantum cryptography, which provides an information-theoretically secure solution to the key exchange problem. Quantum cryptography is an attempt to create a shared and hidden body of data between two users on a common communication channel. This data, which is often in the form of a random string of bits, can be used as a standard secret key for secure communication. Quantum cryptography has an advantage over standard key exchange methods in that information can be proved to be safe in a very strong sense without making assumptions about the intractability of certain mathematical problems. Even if a hypothetical eavesdropper had infinite computing power, the rules of physics guarantee that the secret key exchange will be secure probabilistically.</p> 2022-04-04T00:00:00+00:00 Copyright (c) 2022 JOURNAL OF OPERATING SYSTEMS DEVELOPMENT & TRENDS https://stmcomputers.stmjournals.com/index.php/JoOSDT/article/view/155 Usage of Artificial Intelligence and Machine Learning in Share Market 2022-02-08T07:07:57+00:00 Apeksha Sharma [email protected] Manish Mathuria [email protected] <p>Lately, because of the fast improvement of man-made consciousness (AI) and Machine Learning, its application has been broadly utilized in numerous parts of monetary zone, just as essentially impacts share market, organizations and guideline.

The primary objective of the scheduling algorithms is to optimize the systems’ performance efficiently. The performance of a CPU scheduling algorithm depends on various factors and can be evaluated on various criteria like average turnaround time, average waiting time, throughput, fairness etc. This paper aims to present an optimal CPU scheduling algorithm, Adaptive Quantum Round Robin (AQRR) in a uniprocessor environment. Related work has been done on increasing the performance of existing Round Robin Algorithms using dynamic time quantum approaches, but the maximum percentage gain in turnaround time and waiting time using these approaches, over the traditional Round Robin algorithm is not more than 30% and 40% respectively. The proposed algorithm in this paper outperforms these algorithms in both turnaround time and waiting time. The AQRR algorithm is based on the standard Round Robin algorithm, but it is integrated with a dynamic time quantum which is self-adaptive triggered on the event of the arrival of new processes in the ready queue or the completion of a process in the process queue. The dynamic time quantum is updated based on the remaining burst time of the running processes in the process queue at that instance as well as a weightage associated with it. Finally, a comparative study between the prevailing similar scheduling algorithms and the proposed algorithm is observed and noted, based on different scenarios. The following algorithms are compared on two criteria: average turnaround time and average waiting time.</p> 2021-11-23T00:00:00+00:00 Copyright (c) 2021 JOURNAL OF OPERATING SYSTEMS DEVELOPMENT & TRENDS
