Experience a Faster and More Private Internet in Library and Information Centres with 1.1.1.1 DNS Resolver
Full text linkAs a densely populated country with a large user base, the library and information centres (LICs) in India always suffer from a lack of internet speed. Indian LICs frequently employ open DNS resolvers to achieve high internet speeds. In the new normal, the cyberattacks on Indian educational institutions have skyrocketed, necessitating the development of a more secure and quicker DNS resolver. To meet this demand, the paper assesses Cloudflare\u27s 1.1.1.1 DNS resolver and demonstrates its suitability for Indian LICs. To examine the demand of Cloudflare’s 1.1.1.1 DNS resolver in providing the most secure and fastest private network, the researchers use six Windows PCs connected with ten different networks with the same ISP provider and calculate the Internet speed Measurement Lab and the nPerf online free internet speed checker in Chrome browser (v. 96.0). The internet speed was manually collected before and after the configuration and further analysed to evaluate the increase/decrease percentage. The study findings reveal that after the configuration of 1.1.1.1 set up, the internet speed of the chrome browser in the targeted PCs increased 36.33% for download and 73.88% for upload. And from the result, we can conclude that Indian LICs can rely on the 1.1.1.1 DNS resolver to experience fast & secure private network connections. There are several studies that compare two or more DNS resolvers in terms of speed and security, but none of them specifically addresses their usability and benefits in LICs. Although the usage of DNS resolvers at the institutional level is not a new concept, there is still a lack of understanding among library professionals in India about the deployment criteria and benefits. As a result of this research, library professionals may be inspired to use DNS resolvers comprehensively to provide lightning-fast services to their users
Predicting Faultiness of Program Modules Using Mamdani Model by Fuzzy Profile Development of Software Metrics
Full text linkThis research seminar proposed and implemented a new approach toward reliability and quality measurement of software systems by building a fault prediction model and faultiness degree estimation before starting the testing phase. The main goals of this model were to support decision making with regard to testing phase which leads to reduce the testing efforts, and to optimally assign the needed resources for testing activities. This research used KC2 dataset originated from National Aeronautics and Space Administration (NASA) project to evaluate the predictive accuracy of the proposed model. Software metrics in this dataset are of fuzzy nature, consequently, this work used MATLAB system to build a Mamdani fuzzy inference model. Then, this research applied and validated a published methodology for fuzzy profile development from data as an important requirement to build the model. Moreover, the proposed model utilized the capabilities of k-mean clustering algorithm as a machine learning technique to extract the fuzzy inference rules that were also required to build the model. Finally, this paper used suitable approaches to validate and evaluate the model. Accordingly, the results show that the proposed model provides significant capabilities in fault prediction and estimation
FLOW ANALYSIS ON DELTA WING – A REVIEW
Full text linkMany aircraft, like fighters and bombers, are delta-winged aircraft. These aircraft have the characteristics of producing a greater lift at very small angles of attack even at very low Reynold’s number. Highly swept-wing aircraft experience greater lift due to the generation of the leading-edge vortex at a high angle of attack flight. The phenomena of vortex breakdown are noticed which leads to the reduction of the vortex lift and leads to the instability of the aircraft. This paper deals with an analysis of the flow on the delta wing with the existing literature and compares its benefits over the conventional wings using experimental and computational methods. The critical angles, pressure, and velocity variations are observed along with chord and spanwise locations
Effect of Dihedral and Anhedral on Lateral-Directional Stability of Rectangular Swept back Wing
Full text linkAbstract:
This paper investigates the probable effect a dihedral and an anhedral have on the Lateral-directional stability of an aircraft. In this paper we discuss the basic design of a rectangular swept back wing, designed in the XFLR5 software. We will apply different angles for both the dihedral and anhedral and analyse it using the XFLR5 Software. Our main goal would be to understand the stability criterion, mainly lateral-directional, of the airplane, analysing the graphs that help us understand lateral-directional static stability, compiling all the results and concluding our findings. Furthermore, we will be well-versed in the domain of static stability of an airplane with a rectangular planform which has swept back wings. The design and analysis part of this paper will wholly be covered in the XFLR5 software and the theoretically knowledge of the concept to stability will covered separately in the coming sections
A Study on Concepts De-Laval Nozzle using CFD Tool
Full text linkA device that is used to control the characteristics of fluid is known as a nozzle. Its primary function is to increase the fluid\u27s rate of motion. A traditional De-Laval nozzle will have three distinct parts: a throat, a converging section, and a diverging part. This paper will attempt to detail the bulk of the nozzle concepts developed by De Laval. This paper provides a comprehensive analysis of the nozzle\u27s operational philosophy. In addition, theoretical flow analysis is carried out at a number of locations along the length of the nozzle. The dynamic changes in flow parameters such as pressure, temperature, velocity, and density may be seen with the use of computational fluid dynamics (CFD). The use of CFD is also employed in the simulation of shockwaves

Online Teaching and Assessment Practices using Project Based Approach (Effective Learning with Peers)
Full text linkLiterate population is an important asset for any nation & plays a crucial role while representing the country at internationals. Education makes the backbone of the society, which reveals the skills, knowledge and behaviour transferred from one generation to the next generation. During COVID 19 pandemic, major changes can be seen in the education system. Class room teaching is replaced by an online teaching model to facilitate the students to continue their education. Online teaching methods were adopted by the teachers to maintain the students\u27 learning at all levels. The pandemic has resulted in a change of teaching patterns from traditional classrooms to digital pedagogies. The teaching has become more student oriented rather than on-way teaching methods. These new innovative and active learning practices for teaching pedagogy have enabled the smart teachings for the Education era. The main actor for the Project-based learning is a student, where he/she explores the real-world difficulties for a problem and thus acquires a deeper knowledge by having active learning. The lockdown has actually unlocked multiple prospects to study various online tools for the ultimate stakeholders and facilitators. The purpose of this paper is to present the Online Teaching Learning Model considering Project Based Learning (PrjBL)/ Problem-Based Learning (PBL) for the course “Business Intelligence” as an example to discuss the design of teaching process and problems with engineering students. The proposed teaching pedagogy has evolved with experimental, flexible, peer-learning, learner-centred, discussion-based, knowledge sharing with fun. Thus, the Outcome Based Education (OBE) has effectively improved the teaching and learning skills of students as well as facilitators in this advanced Education Era
Evaluation of Classroom Gamification in Higher Education
Full text linkUsing games for teaching-Learning include features that engage the learners. Gamified instruction builds learning for the better in many ways. First, it empowers students to be responsible for their learning. Well-designed games are particularly effective at keeping reluctant learners engaged because they keep the learner close to but not over their capacity threshold. Second, gamified methods help students maintain a skillful mindset when encountering new obstacles. Moreover finally, gamified instructional techniques build on the ways games boost a player to survive in the face of challenges to help students better overcome hurdles in their learning environment. Engagement of the students in teaching-learning activities plays an important role, but only engaging the students and fun are insufficient, or it could not be the aim. The accomplishment of learning objectives is significant. So games should also be associated with the skill to be evaluated, and evaluation patterns decided by the teacher. During or after the conduction of the game, the teacher should collect the pieces of evidence; must interpret them to get a value with a view to action
