In this paper, Vanadium dioxide (VO2) thin-film devices with two different use cases have been redesigned to introduce an asymmetrical resonant cavity structure. The structure is designed with the goal of enhancing the optical performance of the central VO2 layer and has an anti-reflection property in the cold state. The advantages and limitations of such a design are discussed.
ปัจจุบันมีงานวิจัยเพื่อออกแบบอุปกรณ์ฟิล์มบางทางแสงเป็นจำนวนมาก เราสามารถใช้คุณสมบัติของวัสดุเปลี่ยนเฟส (PCMs) เพื่อออกแบบอุปกรณ์ที่ทำงานได้สองโหมด อีกทั้งยังมีการออกแบบฟิล์มบางให้มีโครงสร้างเป็นช่องสั่นพ้องเพื่อเพิ่มประสิทธิภาพและปรับย่านการทำงานให้เหมาะสม แต่วิธีการออกแบบช่องสั่นพ้องปกติไม่สามารถใช้ได้กับวัสดุเปลี่ยนเฟส งานวิจัยนี้จะเป็นการเปรียบเทียบวิธีการออกแบบช่องสั่นพ้องที่ไม่สมมาตรเพื่อแก้ปัญหาข้างต้น โดยจะเทียบกับวิธีปกติของอุปกรณ์ฟิล์มบางในงานวิจัยที่มีอยู่ โดยแสดงถึงข้อดีและข้อจำกัดของวิธีการออกแบบใหม่นี้

Jaundice, a common condition in infants that results from high bilirubin levels in the blood, often requires early diagnosis and monitoring to prevent severe complications, especially in newborns. Traditional diagnostic methods can be time-consuming and subject to human error. This study proposes an approach for real-time jaundice detection using advanced image processing techniques and machine learning algorithms. By analyzing images captured in RGB color spaces, pixel values are extracted and processed through Otsu’s thresholding and morphological operations to detect color patterns indicative of jaundice. A classifier model is then trained to distinguish between normal and jaundiced conditions, offering an automated, accurate, and efficient diagnostic tool. The system’s potential to operate in real-time makes it particularly suited for clinical settings, providing healthcare professionals with timely insights to improve patient outcomes. The proposed method represents a significant innovation in healthcare, combining artificial intelligence and medical imaging to enhance the early detection and management of jaundice, reducing reliance on manual interventions and improving overall healthcare delivery.

This cooperative education report presents a project for developing a Distributed Control System (DCS) for boilers in a sugar factory. The objective is to enhance the control system for boilers 1-8 to operate cohesively within the DCS framework provided by ABB, utilizing the ABB Ability™ System 800xA software. The overall functionality of the system involves creating a control program that begins with the utilization of bagasse, a byproduct from the sugar extraction process, as fuel for the boiler. The program manages various operations of the boiler, including the intake of air into the combustion chamber, the internal functioning of the boiler, and the treatment of flue gases before their release into the atmosphere. The project encompasses the development of the DCS program, the design and creation of HMI display graphics, the study and design of the boiler control system, the documentation of the project, and the control processes utilizing the ABB Ability™ System 800xA software, culminating in the operational outcomes.
