Consequently, this study was initiated to ascertain whether their respective 5G networks had also been seamlessly integrated several months following the merger. This investigation involved conducting drive tests along two predefined routes within the urban areas of Bangkok, employ...Show More
This paper presents the development of a deep learning model designed to identify two classes of object images, the work-in-process of a kind of tap. There were the good parts of316 images and the defective parts of320 images. Both classes of images were processed using the oversampling technique for data augmentation before transformation. Then, the processed data were applied to training three t...Show More
This paper presents an evaluation of the performance of 5G when the altitude of the test points is changed. In this study, the high-rise building in the crowded public hospital in the urban area of Bangkok that supports a lot of patients every Monday to Friday was selected as the place for the field tests. Two smartphones from the same vendor, which supports 5G, that were installed with the Speedt...Show More
This paper presents the development of a deep learning model designed to identify six distinct types of Thai food dishes, using an imbalanced dataset with 2,736 images. To investigate and solve the imbalance issue, three approaches, consisting of undersampling, oversampling, and hybridsampling approaches, were applied before conducting the augmentation process and transformation. The processed dat...Show More
Nowadays, cybersecurity is an important issue at the personal and organizational levels. Therefore, cybersecurity simulation should be conducted in organizations that are considered critical information infrastructure. According to the simulated phishing attack, during the initial attempt, an email offering a fake promotion from a well-known IT equipment store was sent to employees of a railway co...Show More
The Internet has become an essential part of people’s lives, including e-commerce and online banking. While online transactions are convenient, it also opens up a new opportunity for scammers to easily attack victims. In this paper, data obtained from ChaladOhn, a website that helps prevent Thais from online e-commerce scams, from February 2022 to January 2023 were studied and investigated. Accord...Show More
The recent deployment of 5G New Radio (NR) technology promises to transform the possibility of mobile networks around the world. In many Asian countries, including Thailand, video content, both on-demand and live, dominates the online content market. It’s not uncommon for tourists and content creators to create such content at tourist destinations, then immediately upload them to the social media ...Show More
In Thailand, monitoring of the water situation is important for agriculture (e.g., rice farming) and flood prevention. Therefore, irrigation management requires a system called the automatic report system for water level measurement that will utilize information from remote closed-circuit television (CCTV) cameras and then create the report automatically. This paper presents a pilot study for wate...Show More
One of the key performance indexes used to ensure the quality of the program and the PhD students who complete the program is to publish manuscripts in peer-reviewed journals in reliable database such as Web of Sciences (WoS). However, it is very difficult for PhD students to publish their work, especially in matching the content with the scope of journals and selecting the most appropriate journa...Show More
Online scams have become a new normal risk for online shoppers, including for Thai people. This paper presents a study of online scams analyzed by age, gender and value loss. The dataset for this study is from the ChalaOhn system, a website developed by a state university and the metropolitan police for protection against online shopping scams in Thailand. The dataset was considered, analyzed and ...Show More
During the era of the coronavirus pandemic (COVID-19), online shopping has been growing and the traffic of parcel posts has also increased. However, recipients cannot always be on standby at home to receive their parcels. Therefore, a smart box prototype has been developed to receive parcel posts from the postal service. For sustainable development purposes, this system combines IoT and solar ener...Show More
This paper presents the website called Chaladohn (cha-lad-ohn). This website was designed and developed to aid Thai victims from online scammers; a collaborative project by the Faculty of Engineering, Rajamangala University of Technology Phra Nakhon and the Investigation Division, Metropolitan Police Division 8. The major key features provided by this website are checking and alerting users about ...Show More
This study aims to create a method for identifying and evaluating the factors that impact Cybersecurity Awareness (CSA) of Internet users. Focusing on the employees in the railway organizations in Thailand, seven individual different factors, including attitude, cognitive, experience (in cyber-attacks), education and gender are used to determine and measure the factors associated with CSA of users...Show More
This paper aims to propose the Quality of Experience (QoE) models based on the expectation and/or the perception of 5G users to evaluate for Mean Opinion Score (MOS) for real-time or interactive services/applications with high reliability.
