This work proposes and experimentally demonstrates a very high-accuracy optical-penetration-based silkworm gender identification method. The key to our approach lies in optical noise suppression scheme that involves combination of image magnification, polarization filtering, automatic selection the region interest (ROI). In experimental demonstration, an magnification 5.65 filtering are achieved by merely using 10-mm focal length lens crossed polarizers, respectively. Further, ROI is...
As fast human temperature screening is needed in large public areas, this paper proposes a low-cost mobile platform module that combines the advantages of analyzing visible and thermal images. In particular, key idea relies on face detection image. Then coordinates all faces detected are mapped to image determine their corresponding temperatures. Internal compensation external reference also employed reduce unwanted fluctuation inside surrounding environment. Our module, called , uses FLIR...
Random numbers are important in many activities, including communication, encryption, science, gambling, finance, and decision making. There is a strong demand for hardware random number generator that could support cryptographic applications. In this work, we propose quantum tunneling diode as source of true randomness achieved by applying electrical current sweeps through the device then harnessing time-counting unit to measure fluctuation flows. Our approach can be implemented with...
A recent study conducted in Khon Kaen Province, Thailand, evaluated the effectiveness of a technology-assisted intervention aimed at improving water quality and addressing related health issues communities around key bodies. The targeted concerns associated with contamination, including chronic kidney diseases, skin conditions, hypertension, neurological symptoms. included assessments evaluations 586 residents implemented Learning Innovation Platform (LIP) across 13 communities.

The rice kernel inside a hull is composed of the embryo and endosperm. or germ seed will grow become shoot root parts seedling, while endosperm an important nutrient source for in early stages. Hence, health seedlings depends particularly on sizes In this work, we propose experimentally demonstrate how areas brown can simply be determined. Our key idea based utilization smart mobile device equipped with our specifically designed lens module arranged simple cross-polarization imaging...
Multispectral imaging camera is an important tool for two-dimensional (2-D) and 3-D spectroscopic analysis.

Dimensions of grains are important factors in evaluating the physical quality grains. In this work, we show for first time that thickness, width, and length rice can be simultaneously measured. Rather than imaging only above from a two-dimensional plane, our key idea is to insert tilt reflective surface on measuring plane such side view observed at same time. Demonstration prototype shows very promising result determining grain with maximum values 2.20 mm, 3.65 10.27 respectively. It offers...
Hand reeled Thai silk yarns can be classified based on its physical quality such as diameter, color and weight. In general, certified inspectors are randomly select parts of the yarn evaluate uniformity diameter by their naked eyes. This process is laborious, sometimes gives uncertain results due to experience inspectors, which affects price yarn. To overcome these difficulties, we propose implement an optical sensing system called “Silk Check” for classification hand It determine in real...
Converting infrared radiation in the form of heat into electricity is one interesting energy conversion approaches.
