Cultural tourism is a type of tourism that aims to learn about the culture and way of life of indigenous peoples who have their own culture. Tambon San Pu Loei in Doi Saket District, Chiang Mai is also known as cultural tourism destination where tourist gain information and experience about historical and local people way of life. However, the report from local governments mentioned that tourists had difficulty acquiring information. As a result, the community lacked the ability to communicate the local knowledge in a variety of disciplines since improper storing of data sources and met the problem of coordinates not matching the actual location of the place. In this study, the two-dimensional bar code technology (QR Code) was improved and employed on location-based services for promoting the cultural tourism and utilizing to tackle the problem of tourists accessing information. 83 travelers were involved in this study. Satisfaction level is measured based on 3 parts: content, design, and useful. The overall result of tourist satisfaction who scanned the QR code and visited the website (www.dekdoi-travel.com) is also presented in this paper.
文化旅游是一种旅游，目的是了解文化和生活方式的土著人民谁拥有自己的文化。Tambon San Pu Loei在Doi Saket区，清迈也被称为文化旅游目的地，游客在那里获得有关历史和当地人生活方式的信息和体验。然而，当地政府的报告提到，游客很难获得信息。因此，由于数据源存储不当，社区缺乏沟通当地各种学科知识的能力，并且遇到了坐标与当地实际位置不匹配的问题。本研究将二维条码技术(QR code)改进并应用于地理定位服务，促进文化旅游，解决游客获取信息的问题。83名旅行者参与了这项研究。满意度是基于3个部分来衡量的:内容、设计和有用。本文还给出了扫描二维码访问网站(www.dekdoi-travel.com)的游客满意度的总体结果。

In line with the advancement in technology there is an extensive use of power electronics in the power systems as the demand for more efficient and smart energy grows. The widespread use of power electronics in power transformers can introduce dc bias into the system, causing it to change operating point, generate harmonics and increase excitation current. In this work we have modeled a Y-y type 11kV/433V natural air-cooled power transformer using Ansys Maxwell software. This model has been analyzed using the finite element method. A comprehensive analysis of the flux distribution capability and the influence on the neutral current in a dc biased transformer was performed. This study provides new insights into various zones of operation of the dc biased transformer. The resulting nonlinearity of operation with increasing dc bias could lead in leakage flux, neutral current, and losses, causing a lower lifetime expectancy and poor power quality over time. Collectively, our analysis demonstrates that identifying different operating zones and operating the transformer in the safe operating zone (SOZ) can extend the life of a transformer while also providing significant safety and reliability benefits.

Many people in India are subjected to visual impairment and blindness which are not curable. Most of such people are poor and cannot afford digital equipment for assistance. Visually Impaired or visually challenged people face a lot of difficulty in recognizing the paper currencies during their financial transactions due to the similar texture of paper and dimensions of currency notes. This makes it time-consuming, complex and erroneous at times. The proposed framework is to help visually impaired or blind people by providing them with digital assistance, which will take a photo of the note and notify the user the denomination via speech medium.

The needs of industrial workforces have changed in the Industry 4.0 era. The knowledge worker in charge of information systems and internal operations was divided into different roles, and they each used different working methods and concepts. Despite this, Industry 4.0's consolidation has promoted the growth of servicing workforce with both computational complexity and equipment maintenance skills. An industrial requirements analysis is conducted in this paper to identify the key skills and competencies needed for setting up and designing an Excellence Center in the context of Industry 4.0. A diverse group of industry experts are surveyed to gather their insights on the most important areas of focus for such a center. The findings indicate that the key competencies needed for success in an Industry 4.0 setting include digital literacy, data analysis, and the ability to work with advanced technologies such as artificial intelligence and the Internet of Things. Based on these findings, a curriculum for the Excellence Center is proposed that prioritizes these competencies and includes hands-on training and practical experience. Overall, this paper contributes to the understanding of the requirements for Industry 4.0 and provides a roadmap for setting up and designing an Excellence Center to meet these requirements.

People are becoming more health conscious after pandemic and as a result, smart textile based biomedical devices are becoming popular among people. By incorporating electrical components into the textile items humans use every day, a new hybrid area called “smart textiles for biomedical applications” has been created. Along with conventional textile apparel, these wearable e-textiles provide user-defined applications. One of the main application areas for these new hybrid goods is the medical industry, and rather developed items may be seen both in the lab and on the market. These solutions are made to meet both the specific needs of individual patients as well as continuous patient monitoring in large healthcare facilities. These goods are also being utilised to substitute traditional ways and for complicated medical treatments in the interim. Major focus areas are the smart textiles that are able to measure Electrocardiogram (ECG), Electroencephalogram (EEG), Electromyography (EMG), Electrooculography (EOG), Respiration measurement, Body temperature measurement, Blood pressure measurement, Blood glucose measurement, Sleep analysis. Huge number of researchers across the globe are continuously working for advancement in smart textile based biomedical devices but due to huge manufacturing costs, most of the proposed products are not practically feasible. Another major issue is effectiveness of the sensors after washing as most of such devices are wearable e-textiles, where textile fibres are turned in to conductive materials by using various type of coatings. More dedicated interdisciplinary efforts are required form electronics, medical and textile experts for reduction of manufacturing cost and making the products practically feasible and affordable.

The utilization of microalgae as a bioindicator for water quality assessment has traditionally relied on the expertise of morphological identification. With the advent of technological advancements, particularly the smartphone camera, there has been increasing interest in using it as a tool for various fields of microbiological and medical diagnostics, including image analysis of microalgae. Despite the growing popularity of smartphone-based image analysis, the image quality of smartphone cameras for detecting microalgae has yet to be thoroughly evaluated. Therefore, the purpose of this study was to investigate the suitability of smartphone-based camera for collecting microalgae images and compare it to that of a digital microscope camera. Additionally, the effect of different microscopic magnifications at 100x and 400x on model performance was thoroughly studied. Four models, YOLOv5, RetinaNet, EfficientDet, and Faster-RCNN, were trained on microalgae image datasets taken by both a smartphone camera (SC) and a digital microscope camera (DMC) under 100x and 400x magnification. A total of 11,608 images were divided into three parts: train (70%), validation (10%), and test (20%), with the test dataset separated into four parts for each device and magnification. The results of the study indicated that Faster-RCNN was the best model for microalgae detection, with the highest average precision $(mathbf{AP}^{0.5})$ values of 0.60, 0.84, 0.91, and 0.96 at 100x magnification of SC and DMC and 400x magnification of SC and DMC, respectively. The comparison between the image quality of SC and DMC at each magnification revealed that the SC was less suitable for microalgae identification, particularly at 100x magnification. Conversely, the 400x magnification of SC had the potential to identify microalgae through the use of smartphone-based photography, as well as digital microscope camera.

The results of the study indicated that Faster-RCNN was the best model for microalgae detection, with the highest average precision $(mathbf{AP}^{0.5})$ values of 0.60, 0.84, 0.91, and 0.96 at 100x magnification of SC and DMC and 400x magnification of SC and DMC, respectively. The comparison between the image quality of SC and DMC at each magnification revealed that the SC was less suitable for microalgae identification, particularly at 100x magnification. Conversely, the 400x magnification of SC had the potential to identify microalgae through the use of smartphone-based photography, as well as digital microscope camera.","PeriodicalId":38808,"journal":{"name":"Transactions on Electrical Engineering, Electronics, and Communications","volume":"75 1","pages":"457-462"},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86176468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
