Enhanced remote astronomical archive system based on the file-level Unlimited Sliding-Window technique

Data archiving is one of the most critical issues for modern astronomical observations. With the development of a new generation of radio telescopes, the transfer and archiving of massive remote data have become urgent problems to be solved. Herein, we present a practical and robust file-level flow-control approach, called the Unlimited Sliding-Window (USW), by referring to the classic flow-control method in the TCP protocol. Based on the USW and the Next Generation Archive System (NGAS) developed for the Murchison Widefield Array telescope, we further implemented an enhanced archive system (ENGAS) using ZeroMQ middleware. The ENGAS substantially improves the transfer performance and ensures the integrity of transferred files. In the tests, the ENGAS is approximately three to twelve times faster than the NGAS and can fully utilize the bandwidth of network links. Thus, for archiving radio observation data, the ENGAS reduces the communication time, improves the bandwidth utilization, and solves the remote synchronous archiving of data from observatories such as Mingantu spectral radioheliograph. It also provides a better reference for the future construction of the Square Kilometer Array (SKA) Science Regional Center.

Organizing thematic search in open archive system

Problems of search organization in open archive system are specified and analyzed. The experience of thematic search in digital resources is generalized. The approaches to organizing open archive search interface oriented toward untrained and trained users are characterized. The pros and cons of single search window are discussed. Vectors to improve search instruments and performance are defined. The rubricator version to support thematic search adaptation is proposed. The choice of UDC as the rubricator foundation is substantiated provided that its correspondence with the State Rubricator of Scitech information and Library Bibliographic Classification is set up. The fragment of the suggested rubricator is given as an example. The main purpose of the analysis is to summarize on the problems related to thematic search and to propose approaches to design optimum close-knit rubricator, and to identify its application possibilities.

Smart Final Year Project Archive System Using Laravel Framework with Email Notification (SFYPAS)

Final Year Project (FYP) is a compulsory requirement for graduation of every bachelor programme in Universiti Teknologi MARA (UiTM). Finding a topic for the final year project is quite challenging. However, being able to access previous FYP thesis helps students to generate some ideas. Supervisors and lecturers can also determine whether the proposed project is already among the previous research project or a new one. Unfortunately, the past FYP thesis is usually kept in a specific thesis room. Hence, this will make going to the thesis room and searching the thesis for references quite burdensome. The lack of electronic management for FYP thesis causes several problems in arrangement and search methods. This project aims to develop Smart Final Year Project Archive System (SFYPAS) using Laravel Framework and evaluate the system in terms of technology acceptance model (TAM). SFYPAS is developed using Laravel framework and the methodology used throughout the project is using Software Development Life Cycle (SDLC). The system tested based on its functionality, user acceptance with TAM and heuristic evaluation by an expert. The system was tested on thirty respondents who shared their feedback by answering a set of questionnaires upon completing the testing. The result shows that the mean for user acceptance with TAM in terms of perceived ease of use is 4.27, while perceived usefulness is 4.47. Thus, it shows that the respondents are satisfied with the system in terms of its perceived usefulness. In conclusion, this research has achieved the objectives where it eases the user by providing a web-based smart archive system as a platform to access the past FYP thesis. For future work, the system can be improved by adding a search engine that implements any searching algorithm to yield a better result.

Design of an Enhanced Web Archiving System for Preserving Content Integrity with Blockchain

A Web archive system is a traditional subject for preserving web content for the future and the importance is getting more significant due to the explosive growth of web content. The reference model for an open archival information system (OAIS) has been advising guidance for a long-term archiving system and most organizations that archive web content follow this guidance. In addition, the web archive (WARC) ISO standard is for web content archiving. However, there is no way to secure content integrity, and it is hard to identify the original. Because of limitations, a web archive system has a weakness against the dispute of content integrity. In this paper, we proposed the blockchain linked (BCLinked) web archiving system, which uses blockchain technology and an extended WARC field to keep a web content integrity metadata into a blockchain. Furthermore, we designed the BCLinked web archiving system, and we confirmed the proposed system secures content integrity through the experiment.

Research Archiving As a Tool for Research Continuity: A Look at Bowen University, Nigeria

Aim: The concept of research/project archiving revolves around access to and storage of past works. With the increase in technology, several universities have incorporated the use of electronic archive systems to store research works to provide easy access to such works and improve their research output. Bowen University, Nigeria however, currently runs a manual system of project archiving which is not in tune with the current trend in research archiving. This work was therefore aimed at designing an electronic project archive system for Bowen University that provides accessibility to securely managed past works to cater for the research needs of undergraduate students and enable them to contribute their quota to knowledge. Study Design: An empirical research study design was employed. Place of Study: Bowen University, Iwo, Nigeria. Methodology: A self-constructed questionnaire designed via Google Forms was administered to current students, past students and staff members of Bowen University to collect data on user requirements; data were analyzed and the results served as a platform to develop a user-centred system. The Bowen University Project Archive System (BUPAS) was built with a focus on the authenticity of the materials archived using HTML for the user interface design, PHP for the system logic to communicate with a carefully designed and structured database, and a local host server, WAMP providing back and forth communication. The usability test was also conducted for users. Conclusion: The use of the agile methodology ensured the development of a fully functional system that provides a faster and easier platform for submitting and accessing project works with users attesting to the need for the system and commending the simplicity and easy navigation of the system. Also, a major strength any archive system should possess is its ability to ensure a secure way of depositing into it to guarantee the authenticity of materials that are being accessed. The Bowen University Project Archive System possesses this strength.
