Grain Configuration of Solid Rocket Motor
Get PDFThe solid rocket motor upper stage for a space launch vehicle is a more efficient propulsion technology than the liquid rocket motor upper stage. Its grain design has the potential to be crucial in terms of lowering inert mass by adopting improved volume efficiency with the lowest practicable sliver size while keeping maximum strength. Specifically, the strategy for (3D) grain arrangement of the slot for the upper stage solid rocket engine has been described in this paper. The complex configuration is established by the design process, which takes place under a parametric model of geometry in (CAD) software and is typified by varied dynamics. When constructing solid propellant rocket motors, grain arrangement is a vital and critical step. Accurate estimates of grain geometric properties play a key role in performance prediction and can be a vital and critical stage in the design of solid propellant rocket motors. This research study proposes an effective performance-matching design framework for solid rocket motors that are tuned to suit a range of thrust performance criteria. The framework is constructed utilising an innovative and specialised general design technique that was designed to evaluate the general design parameters, which is given in this study. Because of the findings obtained, it can be stated that the recommended framework is a practical and efficient approach for solid rocket engine design and development

Use of assignment mode for effective assessment of students to achieve course outcomes
Get PDFTo ensure the quality learning of students, course outcome assessment is vital element of outcome based education. To achieve course outcomes, various modes of pedagogy and assessment are essential. There are different modes of assessment for In-semester examination like multiple choice questions, time bound pen and paper, presentations, seminars, assignment etc. This paper explains the use of assignment mode for effective assessment of students. This paper highlights how assignment mode helps students to apply concepts taught in classroom to solve various problems on applications of engineering mathematics. We had done assessment of 610+ F. Y. B. Tech students by giving different assignment to each student which included different set of questions for the course Linear Algebra and Univariate Calculus with time bound submission. This ensured that students have to solve the assignment independently without taking help of peers. This paper describes how assignment mode has improved various competencies of students. This paper is illustrated with responses of F. Y. B. Tech students. The proposed method is useful for online and offline mode of examinations

IoT Ecosystems Enable Smart Communication Solutions: A Case Study
Get PDFThe Internet of Things (IoT) is a platform for innovation, allowing people to invest in and use IoT to improve life, business, and society. It will be applicable to all or any industry sectors, verticals, people, machines, and everything. This creates difficult requirements in terms of higher system capacity, extremely low latency, such as for the tactile Internet, extremely high throughput values, a wide range of services, such as IoT and M2M, and a more uninterrupted experience. As a symbiotic confluence of up to date and existing technologies, the IOT architecture will use Hetnet RAN, Cloud enhanced RAN, and SW defined data centres to combine novel and legacy technologies. As a result, IOT will combine next-generation largearea extensible service experiences anytime and anywhere, with ultra-dense installations, nearzero latency, and GB experiences–when and where it matters. Collaboration on research, standardisation, and spectrum sharing with the IT/Internet world, industry verticals, policymakers, and academia is a significant success element. Trillions of dollars in smart ecosystems prospects covering secure connections, digital service enablement, applications and repair provisioning, and a wide range of internet of things and consumer applications are available to communications service providers and enterprises
AN EFFICIENT THRESHOLD SECRET SHARING SCHEME USING FAST FOURIER TRANSFORM
Get PDFSecret Sharing is a robust key management method which is having applications in password management, secure multi party computation, e-voting etc. Threshold secret sharing is a method in which out of all the parties only predefined or certain number of parties can reconstruct the secret. In this paper we will describe the most popular Shamir’s secret sharing scheme along with its limitations. In Shamir’s scheme each shareholder receives one share per secret. We can use alternative way ramp (packed variant) scheme which overcomes this limitation and reduces load on each individual shareholder. But this impacts on efficiency as degree of polynomial is increased. Either we must adjust the privacy threshold or number of shares needed to reconstruct. There is need of advance technique. An efficient secret sharing needs faster polynomial evaluation and interpolation. Here is an efficient secret sharing scheme using Fast Fourier Transform (FFT). In this polynomial evaluation as well as interpolation both speeds up. It has time complexity O(n log n)
A Quantitative Study of Risk Scores and the Effectiveness of AI-Based Cybersecurity Awareness Training Programs
Get PDFCybersecurity awareness training plays a dynamic role for organizations in certifying resources\u27 accessibility. This paper determines the correlation between an employee\u27s risk score and the effectiveness of AI-based security awareness training that deals with cyber threats. The research uses the Unified Theory of Acceptance and Use of Technology to update prior research, revealing that at-risk employees\u27 behavior and information security awareness training implementation make up successful interventions. However, those studies did not discuss AI training, and so this research fills that literature gap. This study used a quantitative research design. The researcher analyzed survey responses using Pearson\u27s Correlation and an independent t-test to determine statistically significant relationships and differences between employees\u27 risk scores and an AI-based security awareness training programs\u27 effectiveness. The calculations came from a sample of 200 participants from two different organizations. The Pearson product correlation of employee\u27s risk scores and the effectiveness of the security awareness training program was statistically significant. The researcher also conducted an independent-samples t-test to compare the employees\u27 risk scores by gender. There were no significant differences in scores. Male was higher than female ones. The mean difference was minimal. The findings herein help interpret the role of information security awareness training in the workplace, promoting behavioral changes that would impede data violations by including the users\u27 vulnerability and the severity of intimidation, and the response to a threat in prognosticating behavior intentions
