Computational Facilities and Web-Resources: Case Study of Large Private University with Fast-Growing Clients

Speed, space and judicious sharing web-related resources are the key indicators of successful management of the computing-facilities and other web-resources of any progressive organisation. Such a case becomes much more demanding for any professional academic institution, where the majority stake-holders, that is the young student-users of web-resources, are heavily dependent on web-based learning and personal communications. Other stake holders, like administrative staff, teaching and research community of universities have web-dependence, mostly for known resources. Fast growing dependence of different categories of stake-holders of such large institutes warrants a case-study research, so as to study the present pattern of uses of web-resources, including the timing and pockets of users, and then to have a sustainable strategic planning for a better resource-management of web-resources for future. The present paper is a case study of a leading private university of Odisha (in India) with over 65,000 users of ‘university web-network' and over 7500 fixed-systems, which analyses users' time-series data of last quarter and suggests a futuristic model for optimal and effective use of - ˜Institute Web-Resources and computing facilities'. It studies both fixed-line load and load-management of wireless (Wi Fi) connections, across the 25 campuses of the Institute, scattered and geographically located within 15 sq. km

The evolution of transformative communication patterns in 1-to-1 computing classrooms

This research explores the evolution of communication patterns in 1-to-1 classrooms of teachers who vary in their years of experience teaching in these computer-rich classrooms. The context for this study was classroom observations and teacher interviews in 7 Milwaukee public schools during the spring of 2010 where teachers were implementing a 1-to-1 computer program in which every student was given a laptop. The researcher used an explanatory mixed-methods design in which both quantitative and qualitative data were collected. The researcher compared data collected through classroom observations and teacher interviews from 5 teachers in the first year of the program and 6 teachers who had been in the program for 2 or more years. The overall findings suggested a shift from more traditional forms of instruction toward constructivist teaching styles when comparing the 2 groups. The researcher compared classroom organization, technology use, communication patterns, and student identity in the 2 groups of teachers. Teachers with more experience in the 1-to-1 program structured instruction to allow students to work in small groups more often. They also used technology as a tool more often to mediate communication. The research also revealed that when students have ubiquitous access to real-time formative assessments, new forms of student-centered communication patterns occurred. Another finding was that student identity often changes in 1-to-1 computing environments from a passive role to taking on more responsibility, acting as experts, and becoming more engaged in their own learning. Ongoing professional development was found to be an important factor in helping teachers evolve their teaching practices. These positive findings suggest that communication patterns in 1-to-1 classrooms do evolve toward more transformational forms of communication over time

INDEPENDENT PROJECT BASED LEARNING: APPLYING KNOWLEDGE BY CREATING A LOW-COST SUPERCOMPUTER WITH RASPBERRY PI

This article was written to detail the process of one-on-one project based learning and the benefits to the student. Students are increasingly seeking opportunities to gain experience with developing technologies that interest them personally, but may be beyond the planned curriculum. This paper explores an independent project of a student creating a supercomputer by using the parallel processing power of ten Raspberry pi. Traditionally computing is executed one instruction at a time, usually using a single processor. The speed in which instructions are completed depends on how fast data moves through the hardware. Parallel computing is a faster way to process instructions by breaking the large task into smaller tasks using a coordinated effort to process data simultaneously. Parallel computing is typically handled by supercomputers that range in costs from the hundreds of thousands to over a billion dollars

CHEATING DETECTION IN ONLINE EXAMS BASED ON CAPTURED VIDEO USING DEEP LEARNING

Today, e-learning has become a reality and a global trend imposed and accelerated by the COVID-19 pandemic. However, there are many risks and challenges related to the credibility of online exams which are of widespread concern to educational institutions around the world. Online exam system continues to gain popularity, particularly during the pandemic, due to the rapid expansion of digitalization and globalization. To protect the integrity of the examination and provide objective and fair results, cheating detection and prevention in examination systems is a must. Therefore, the main objective of this thesis is to develop an effective way of detection of cheating in online exams. In this work, a system to track and prevent attempts to cheat on online exams is developed using artificial intelligence techniques. The suggested solution uses the webcam that is already connected to the computer to record videos of the examinee in real time and afterwards analyze them using different deep learning methods to find best combinations of models for face detection and classification if cheating/not cheating occurred. To evaluate the system, we use a benchmark dataset of exam videos from 24 participants who represented examinees in online exam. An object detection technique is used to detect face appeared in the image and crop the face portion, and then a deep learning based classification model is trained from the images to classify a face as cheating or not cheating. We have proposed an effective combination of data preprocessing, object detection, and classification models to obtain high detection accuracy. We believe that the suggested invigilation methodology can be used in colleges, institutions, and schools to look for and keep an eye on suspicious student behavior. Hopefully, by putting the proposed invigilation method into place, we can aid in eliminating and reducing cheating incidences as it undermines the integrity and fairness of the educational system

Una extensión a los esquemas preconceptuales para el refinamiento en la representación de eventos y la notación matemática

An event is an occurrence within a particular software system or domain. Software and scientific models are representations of computing and natural systems. Such models have software and scientific components—domain knowledge elements. Scientists and business analysts use such models and their components for recognizing a domain, e.g., pre-conceptual schemas (PCS) used in software engineering. Scientific software domains (SSD) comprise fields in engineering and science, which are focused on developing and simulating scientific software systems for event or phenomenon research. Event-based software development has increased in scientific domains. Approaches to event-driven modeling are used from software/scientific modeling. Some advances have emerged in such approaches for integrating software and scientific components in science and engineering projects. However, scientists and business analysts lack a computational model for SSD in order to integrate both components in the same model. PCS notation includes software components based on structural and dynamic features, which allow for representing events and mathematical operations. Nonetheless, PCS lack scientific components for representing events in SSD. In this Ph.D. Thesis, we propose an extension to pre-conceptual schemas for refining event representation and mathematical notation. Such an extension comprises scientific components as graphical, linguistic, and mathematical structures for the sake of such refinement. We validate our proposal by using both an experimental process and a software application. Extension to PCS is included as a new work product for representing events in SSD. Therefore, the extended PCS are intended to be computing models for scientists and business analysts in scientific software development and simulation processes.Un evento es una ocurrencia en un sistema de software o dominio particular. Los modelos científicos y de software son representaciones de sistemas informáticos o naturales. Esos modelos tienen componentes científicos y de software (elementos del conocimiento del dominio). Científicos y analistas de negocio usan estos modelos y sus componentes para reconocer un dominio. Un ejemplo de esos modelos son los esquemas preconceptuales (EP), que se usan en ingeniería de software. Los dominios de software científico comprenden áreas en ingeniería y ciencia que se enfocan en el desarrollo y simulación de sistemas de software científico para la investigación de eventos o fenómenos. El desarrollo de software dirigido por eventos se viene incrementando en dominios científicos. Enfoques de modelado basado en eventos se usan desde el modelado científico y el modelado de software. En estos enfoques surgen algunos avances para integrar componentes científicos y componentes de software en proyectos de ingeniería y ciencia. Sin embargo, científicos y analistas de negocio carecen de un modelo computacional para dominios de software científico que integre ambos componentes en el mismo modelo. La notación de los EP incluye componentes de software que se basan en características estructurales y dinámicas, los cuales permiten representar eventos y operaciones matemáticas. No obstante, los EP carecen de componentes científicos para representar eventos en dominios de software científico. En esta Tesis Doctoral se propone una extensión a los esquemas preconceptuales para el refinamiento en la representación de eventos y la notación matemática. Esta extensión integra componentes científicos (estructuras gráficas, lingüísticas y matemáticas) para lograr este refinamiento. También, se valida la propuesta mediante un proceso experimental y una aplicación de software. La extensión a los EP se incluye como un nuevo producto de trabajo para representar eventos en dominios de software científico. Por lo tanto, se pretende que los EP extendidos sean modelos de computación, para científicos y analistas de negocio en procesos de desarrollo y simulación de software científico.MincienciasDoctorad

Crowdfunding Non-fungible Tokens on the Blockchain

Non-fungible tokens (NFTs) have been used as a way of rewarding content creators. Artists publish their works on the blockchain as NFTs, which they can then sell. The buyer of an NFT then holds ownership of a unique digital asset, which can be resold in much the same way that real-world art collectors might trade paintings. However, while a deal of effort has been spent on selling works of art on the blockchain, very little attention has been paid to using the blockchain as a means of fundraising to help finance the artist’s work in the first place. Additionally, while blockchains like Ethereum are ideal for smaller works of art, additional support is needed when the artwork is larger than is feasible to store on the blockchain. In this paper, we propose a fundraising mechanism that will help artists to gain financial support for their initiatives, and where the backers can receive a share of the profits in exchange for their support. We discuss our prototype implementation using the SpartanGold framework. We then discuss how this system could be expanded to support large NFTs with the 0Chain blockchain, and describe how we could provide support for ongoing storage of these NFTs
