This research explored the potential of artificial intelligence (AI)-assisted learning using ChatGPT in an engineering course at a university South-east Asia. The study investigated benefits and challenges that students may encounter when utilising ChatGPT-3.5 as tool. developed AI-assisted flow empowers learners lecturers to integrate into their teaching processes. was subsequently used validate assess variety exercises, tutorial tasks assessment-like questions for under study.

Purpose The transfer of knowledge has been identified as an important part the family business succession process. This paper examines process from founder to successor understand and model factors that influence in Vietnamese context. Design/methodology/approach research adopts inductive qualitative approach, conducting face-to-face semi-structured interviews with five father-son pairs. founders successors, ten total, formed basis case studies. cases were all at advanced stage succession....
Purpose Many family businesses do not survive into the second generation. A common reason put forward for this is poor succession planning This paper designed with aim to explore role of father in supporting son’s business knowledge and development Vietnamese businesses. Design/methodology/approach research adopted an inductive qualitative approach using multiple face-to-face semi-structured interviews five father–son pairs. The interview participants were a cross section businesses, where...
In this paper we present a new approach for the detection of lip centers based on eye localization that is adopted into reading system in mobile environments. First, left eyes and right are localized directly. Then use geometry characteristics faces to extract rough regions. Next, 2 steps threshold adaptation binarize images. The first used estimate standard each image; second one applied compute thresholds image threshold. Finally apply Sobel edge map filter with projections detect precise...
<h1>The purposes of this study are to explore in detail the tacit business knowledge transfer process and effective method from founder successor Vietnamese family businesses. This study, using separate interviews paired founders successors five businesses, aims contribute general understanding such processes South East Asian confirms that is an on-going until unable continue due physical or mental health preventing further communication. In addition, it indicates mentor-mentee most...
This study investigates the complex interplay among student experience, engagement, and academic success in online learning. Its primary goal is to understand how quality of experience influences their engagement achievements. The research followed a rigorous four-phase approach, starting with thorough literature review establish strong theoretical foundation. Pre-validated constructs measurement items were selected suit nuances learning diverse population Vietnamese universities. core...
음성 인식 기술은 편리한 삶을 추구하는 요즘 추세에 HMI를 위해 매력적인 기술이다. 인식기술에 대한 많은 연구가 진행되고 있으나 여전히 잡음 환경에서의 성능은 취약하다. 이를 해결하기 요즘은 청각 정보 뿐 아니라 시각 정보를 이용하는 음성인식에 활발히 있다. 본 논문에서는 모바일 음성인식을 위한 입술의 탐지 방법을 제안한다. 위해서는 정확한 탐지가 필요하다. 우리는 입력 영상에서 입술에 비해 보다 찾기 쉬운 눈을 이용하여 눈의 위치를 먼저 탐지한 후 이 대략적인 입술 영상을 구한다. 구해진 영상에 K-means 집단화 알고리듬을 영역을 분할하고 분할된 영역들 중 가장 큰 선택하여 양 끝점과 중심을 얻는다. 마지막으로, 실험을 통하여 제안된 기법의 성능을 확인하였다. Automatic speech recognition(ASR) is attractive technique in trend these day that seek convenient life. Although many...
음성 인식 기술의 발전에도 불구하고 잡음 환경하의 인식은 여전히 어려운 분야이다. 이를 해결하기 위한 방안으로 정보 이외에 시각 정보를 이용한 음성인식에 대한 연구가 진행되고 있다. 하지만 또한 음성과 마찬가지로 주위 조명 환경이나 기타, 다른 요인에 따른 영상잡음이 존재하며, 이런 영상잡음은 인식의 성능 저하를 야기한다. 따라서 향상을 위해 특징 파라미터를 어떻게 추출하느냐는 하나의 관심분야이다. 본 논문에서는 HMM기반 음성인식의 영상 기반 접근방법에 파라미터의 추출 방법에 대하여 논하고 그에 인식성능을 비교하였다. 실험을 105명에 화자에 62단어의 데이터베이스를 구축하고, 이용하여 히스토그램 매칭, 입술 접기, 프레임 간 필터링 기법, 선형마스크, DCT, PCA 등을 적용하여 추출하였다. 실험결과, 제안된 의해 추출된 인식기에 적용하였을 때의 성능은 기본 파라미터에 비해 약21%의 향상이 됨을 알 수 In spite of development in speech...
