This research proposes some useful and practical techniques to design and implement the real-time embedded data acquisition and classification. A web-based used as graphical user interface is also provided to visualize data, parameters and behaviors of the proposed system. A low-cost microcontroller is chosen to run special bootloader and application program. The application program is designed and implemented using non-blocking event-driven realtime operating system. It reads data from sensors, performs K-means classification algorithm, and sends data and system states to the web-based application running on a web browser. In addition, the microcontroller system is designed to support many IoT applications. It is composed of all basic inputs and outputs, e.g., ADCs, PWMs, Wi-Fi, USB-to-UART and data storage. The users can visualize the measured data and examine behaviors of the K-means algorithm on the web browser in real-time. The web-based application is designed and implanted using new technology of web-based application development techniques. It can be run on any device that has web browser. The microcontroller and web-based application can exchange their data over internet network using HTTP, MQTT or WebSockets protocol. It supports serial port communication as well. The experimental results show that the proposed system and algorithms running on the microcontroller and web browser can perform data acquisition and classification in real-time manner and it can be used in real-world applications as expected.

The Aerial Surveillance is an effective method to inspect overhead power transmission line in complicated geographical terrains. However, the practical automatic method is still needed to improve the inspection efficiency. The Canny-Edge detector and Hough transformation are used to extract the power transmission tower straight-line feature. Then, we use object-based image classification to classify the straight-line. The experiments from a set of real-world video sequence have shown the excellent performance of our approach in term of the receiver operating characteristic curve.

Taxis play an important role in urban transportation. Understanding the taxi demand in the future gives an opportunity to organize the taxi fleet better. It also reduces the waiting time of passengers and cruising time of taxi drivers. Even, there are some works proposed to predict the demand of taxi but there are few studies that consider the function of areas such as hospital area, department store area, residential area, and tourist attraction. One predictive model may not fit with all types of area. We use a point of interest (POI) to match taxi demand with a place to study the taxi demand in the area with a different function. In this paper, we investigate the best predictive models that can forecast demand of taxi hourly with 7 types of area function. The models that were selected for the experiment are long short term memory (LSTM), gated recurrent unit (GRU) and extreme gradient boosting (XGBOOST). Then, we proposed the ensemble model that can forecast the taxi demand well with all types of area function using the information from those machine learning models. We build the models based on a real-world dataset generated by over 5,000 taxis in Bangkok, Thailand for 4 months. The result shows that the proposed ensemble model can outperform other models in overall.

Reducing energy consumption in building is an important motivation for building energy monitoring and management system. In this work we focus on AC current measurement for small to large appliances such as air conditioners. Today's market has many low-cost AC current sensors that use different technologies and come with different usage convenience. This paper aims to compare AC current measurement accuracy for four low-cost current sensors in nowadays market. They are ACS712, WCS1800, SCT013, and PZEM004T. We also discuss about their price and difficulty of installation. We use ESP32 wifi-microcontroller to process measurements. We perform the test using AC loads in small steps from zero up to 20 A. Our results show that PZEM004T gives the best performance among these sensors. However, ACS712 is the best value current sensor because of its low price and performance, although it is more difficult on installation.

This research purposed to study the method to reduce defective parts or parts that are detected an error for automotive wire assembly of the factory case study. The objective is to reduce the defective parts or the terminal problems. Starting from studying, surveying, data collecting of details and problems, it was found that the terminal problem arose from the fact that it is hanged with the glove resulting in bending and damage until it is unable to be used. Consequently, the authors must search for the solution of the terminal problem with LEAN theory in order to achieve the objective. The tools in this research included Why Why analysis, Affinity Diagram, and Pareto charts to realize the cause of problem why the terminal hanged with the glove because the glove of wire assembly staffs currently has tiny gaps on the palm which is the reason of the hook. The solution is to change the glove for operation and after the replacement, the mean of the terminal problem from 13.80 pieces per month decreases to 0% as expected.
