Development of mesoscopic imaging system for surface inspection / Moe Win
Get PDFThe technology of mesoscopy brings into sight the microscopic level details of objects that are in dimensions of several meters, and the mesoscope is the device used for this purpose. The strength of this technology is that it can acquire ultrahigh-resolution images with micro to mesoscopic precision but with higher spatial resolution than a conventional microscope, and is able to solve the field of view limitations associated with optical microscopy. One of the main objectives of this is to develop and build a mesoscopic imaging system that can be used practically as an analytical tool for surface inspections. In particular, the focus is on the development of high-resolution images acquisition and advanced image processing algorithms which could be integrated with the surface inspection and diagnostic system. For this purpose, a high-resolution scanner consisting of a line CCD camera, lens, frame grabber and light source is used for acquiring high quality images of up to 5000 dpi (~5μm/pixel) with micro-mesoscopic spatial range. The post-processing system is mounted with image acquisition system, able to produce very sharp and high-resolution images. The high-resolution images of the samples are subjected to a manual inspection and automatic detection procedures. For the manual inspection, the images are processed and analyzed using raster graphics editors and the micro-meso scale defects are manually identified. The developed system is then utilised for inspection and defect detection of titanium coated surfaces, although appearing uniform, exhibits non-visible micro-cracks which remains hidden from naked eye observations. At high resolution range (above 600 dpi), non-uniformity and tiny defects could be easily detected by the developed mesoscopic imaging system. The results obtained are compared with those obtained from optical microscopy to verify the accuracy of detection. For the automatic inspection, defect detection algorithms based on image thresholding are developed and implemented as a statistical approach to identify possible defects. Existing thresholding-based and clustering-based methods are tested and compared to achieve faster and more efficient algorithms. Two new thresholding methods were developed. These are Contrast-Adjusted Otsu’s Method and Contrast-Adjusted Median-Based Otsu’s Method, which were then integrated into the automatic defect detection system. The proposed imaging system was shown to be capable of efficiently detecting microscopic surface features at any point of the scanned surface since the imaging system can provide ultra-high-resolution images. Also, as the design of the mesoscopic imaging system is built on line-scanning technology, measurements of colour fidelity and spatial accuracy is better than most other imaging systems. The significant findings of this research confirm that the proposed mesoscopic analytical imaging system is a novel approach in non-destructive measurement of surface coating quality
A STUDY ON THE SUSTAINABILITY OF ASSESSMENT CENTERS ACCREDITED BY NATIONAL SKILLS STANDARD AUTHORITY (Tin Moe Win, 2019)
Get PDFThe objective of this thesis is to analyse the factors influencing on
sustainability of assessment center accredited by National Skills Standard Authority
NSSA and to make proper recommendations for future improvement. In this thesis,
the survey was conducted based on 107 accredited assessment centers by National
Skills Standard Authority NSSA. This survey mainly uses descriptive method based
on qualitative and quantitative approaches. The survey found that assessment cost,
preparation and monitoring efforts are important in running assessments successfully.
Moreover, it found that appropriate fees to be considered to collect from the candidate
and employers are important for sustainable assessment center. The survey found that
Government should subside for improvement of occupation assessment system.
Government regulation should be strongly. Certificate by occupational assessment
process is very important. National Certificate is required for the employers. At the
present employer need to skill worker accredited by assessment process because of
productivity and company image. The survey found that that job opportunities is
validity in ASEAN . Bench Marking System is on going process in regional as Thai
and Myanmar , etc. This thesis analysis assessor and inspector fee by ACC
(assessment and certification committee). The follow by employer and employee

A Study on Challenges and Opportunities of Myanmar Immigrant Workers in Japan’s Adult Care Service Sector (Khin MOe Moe Win, 2025)
Get PDFThis study examines the challenges and opportunities encountered by Myanmar
immigrant workers employed in Japan’s adult care service sector. The primary
objective of this research is to explore the lived experiences, workplace integration, and
professional contributions of Myanmar care workers in Japan, with the aim of
identifying both systemic challenges and potential areas for policy and institutional
improvement. Employing a mixed-methods approach, the study collected primary data
through structured surveys administered to Myanmar caregivers working in a range of
institutional and home-based care environments across Japan. Descriptive statistical
analysis and cross-tabulation techniques were utilized to assess factors influencing job
satisfaction, well-being, language adaptation, and social integration. The findings
reveal that language barriers, cultural adaptation difficulties, and labor conditions such
as long working hours and limited social mobility remain persistent challenges.
However, the study also highlights several opportunities: Myanmar workers play a
crucial role in filling urgent labor shortages, contribute to cultural diversity in care
practices, and demonstrate resilience through peer networks and skill development
initiatives. The study concludes with policy recommendations to enhance support
systems, such as the provision of targeted language and cultural training, improved
labor protections, and pathways to long-term residency and career advancement
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
