Abstract

The preservation and enhancement of historical news video archives represent a critical challenge in digital archiving. This paper proposes a novel dual-stream approach leveraging modified conditional Generative Adversarial Networks (GANs) for simultaneous enhancement of video and audio quality in historical news footage. The framework incorporates parallel processing pathways for video and audio restoration, connected through an innovative feature fusion mechanism. The architecture introduces several key improvements, including temporal-aware processing modules, multi-scale discriminators, and adaptive feature fusion strategies. Comprehensive experiments conducted on a diverse dataset of historical news broadcasts from 1960-2000 demonstrate significant improvements over existing methods, achieving a 35.2% increase in Peak Signal-to-Noise Ratio (PSNR) and 29.8 dB improvement in audio Signal-to-Noise Ratio (SNR). The proposed framework maintains temporal coherence while preserving content authenticity, addressing critical challenges in archival media restoration. Quantitative evaluations show superior performance across multiple quality metrics, while qualitative assessments confirm enhanced perceptual quality and historical accuracy preservation. The experimental results validate the effectiveness of the dual-stream approach in historical news video restoration, establishing a new benchmark for automated archival media enhancement.

Abstract

In the rapidly developing digital era, information systems have become an important element in increasing efficiency and effectiveness in various activities. As an important part of public services, queuing services withstand significant challenges in managing rapid population growth. Long waiting times and inefficient queue management can result in user dissatisfaction, increased workload for service providers, and potentially harm productivity. This research aims to overcome these challenges by identifying, pivoting, and creating an innovative information system integrated with the popular cross-platform application, WhatsApp. The main focus is automating queue service management to increase efficiency and user convenience. The resulting system is expected to provide significant changes in public services, reduce waiting times, and make queue management easier. The Unified Modeling Language (UML) methodology is used in the design of this system, providing systematic guidance to achieve these goals. In this research, we identify problems, user needs, functional requirements, and non-functional systems, including queue registration, queue management, user management, and service management. The results include use case diagrams, activity diagrams, sequence diagrams, and class diagrams, which provide a detailed overview of various aspects of the system. The results of this research can serve as a guide for application developers and demonstrate the benefits of UML in designing complex information systems.

Abstract

This study aims to compare manual calibration methods with automated calibration methods based on the Internet of Things (IoT) for scale weights, in accordance with the OIML R-51-1:2006 standards. The research employs three distinct types of scale weights: Cylindrical Knob, Cylindrical Hook Weight, and Cylindrical Slotted Weight. The comparison of these calibration methods is carried out using two key metrics: Correction Values and Standard Deviation Analysis. The experimental results indicate a trend where the accuracy of calibration diminishes as the weight of the scale increases. Specifically, when evaluating the three types of scale weights at a nominal test weight of 50 grams, the correction values obtained are relatively small, showing differences of 0.12, 0.1, and 0.02 for Cylindrical Knob, Cylindrical Hook Weight, and Cylindrical Slotted Weight, respectively. These findings suggest that the impact of weight on calibration accuracy is consistent across the types tested. In addition, Standard Deviation Analysis reveals that the IoT-based automated calibration method consistently achieves lower standard deviation values compared to the manual method. This indicates that the automated method provides more consistent and reliable calibration results. Overall, the study concludes that the IoT-based automated calibration method offers a significant improvement in performance over traditional manual methods for all three types of scale weights. This advancement highlights the potential for IoT technology to enhance the accuracy and efficiency of calibration processes in various industrial applications.

Abstract

This research simulates the use of QuillBot Grammar Checker in assessing students' writing errors in English essays. This research is descriptive qualitative. QuillBot announces the availability and accessibility of a new grammar checker. QuillBot's grammar checker can help users (teachers/lecturers) check writing errors in grammar, punctuation, and spelling. The analysis shows that two examples of students’ essays are evaluated by QuillBot Premium. The 1st student’s essay shows 209 words with 21 errors. It consists of grammatical errors (word class) such as nouns, pronouns, prepositions, conjunctions, and adjectives. The 2nd student’s essay shows 161 words with 20 errors. It consists of grammatical errors (word class) such as nouns, pronouns, prepositions, conjunctions, adjectives, and interjections. Users can choose two options (replace or ignore). Replace means change the error words, while ignore means keep maintaining the words In using QuillBot, users type Quillbot in the Google search engine, log in if needed, several menus will appear, and click Grammar Checker. Write or copy the English essay that we want to check. Errors in writing will appear with red underlines completed by many words and the number of errors in an essay. If we want to click repair, select Fix All Errors. QuillBot utilizes Artificial Intelligence (AI) to automatically scan text for grammatical, punctuation, spelling, punctuation, and capitalization issues, highlighting them and allowing users to correct them individually or in bulk with a single click. Teachers/lecturers can use corrective evaluations by using QuillBot as an alternative online tool besides the popularity of Grammarly. Regarding the accuracy level of using QuillBot in evaluating students' writing errors, it may need to be improved. However, other online grammar check applications can be considered and tried besides evaluation manually.
