In the pandemic of Covid-19, online teaching becomes an important method in education. Different online teaching resources are available such as Tencent (QQ) course groups, Tencent conferences, and Massive Open Online Course (MOOCs). The traditional teaching has also been converted into online platforms. Thus, teachers need to learn and use many information technology applications and training skill packages. This research mainly discusses online teaching and students’ response to the online course of Chinese culture. Online teaching is simple to operate and achieve the practical purpose of teaching.

This research proposes an odometry-free mobile robot system that calculates navigation information based on dead reckoning using a control signal and a robot's dynamic model to construct the system at a minimal cost. The navigation system using control input has errors due to uncertainties such as road conditions of the operating environment, wheel slip, and inaccuracy of the control cycle. In this study, a position using magnetic map matching compensates for the cumulative error, and the yaw is measured by the gyroscope for the orientation angle error. The performance improvements are confirmed via simulations.

Artificial intelligence and Internet of Things (AIoT) technology were applied to develop an integrated system for remote space authentification and power management. The system is applied to various commercial uses such as the control of mobile or cloud authorization in buildings and the management of shared offices or hospitals. To develop the proposed system, AIoT smart lock with low power consumption was designed to control the access and manage the power consumption of other IoT devices effectively in the venue. AIoT communication firmware and devices were developed to enable smart control and management. Finally, an energy management system helps enterprises monitor the power consumption of devices in real-time and grant authorization for device monitoring and management. The proposed system sends monitoring data to a cloud server and enables the managing of commercial activities and unmanned venues.

A BIM-based system is developed to monitor and visualize user information in real-time. By building in-use stages, advantages in tracking facial recognition should be revealed through the availability of real-time information. In this way, the possibility of improving BIM and IoT for data-oriented facility management is investigated. SyncBIM, the integration system is developed on 5 design rules: (1) 3D Information Model Aiding Decision-making, (2) Object orientation design delivering service, (3) Dynamic DB based on real-time monitoring, (4) Mapping data-driven visualized results, and (5) Hierarchical Integration of Contextualized Spatial Information. In this research, we demonstrate the SyncBIM system of real-time facial recognition with appropriate parameters.

A micromachined capacitive vibration sensor is proposed in this work for machine tool condition monitoring. The sensing element design, readout circuit, system module design, and experimental results are also investigated. A systematic FIR compensation filter for the proposed vibration monitoring system enhances the flatness of the passband frequency so that the output amplitude of the sensor keeps near a constant under different excitation frequencies. The passband flatness of the compensated MEMS vibration sensor is about 7.5% with the 5kHz bandwidth and the noise density is about $31mu g/sqrt {Hz} $. Finally, the vibration sensor is characterized and verified by the metal milling process for the performance and the feasibility for machine condition-based monitoring.

Recently, the application of Unmanned Ground Vehicle (UGV) has been increasingly prevalent. It can be used in different applications both indoors and outdoors. However, for some scenarios, the Global Positioning System (GPS) may not be always precise and available due to signal attenuation and multi-path propagation. Hence, in this research, we use a novel vision-based architecture, including machine learning and edge computing, to analyze the geometric features to find the path. Furthermore, we also intend to perform a scenario analysis for obtaining the setting with better performance. According to the experimental results, the prototype demonstrates the appropriate performance and properties.

The heat generation in the machining process at the cutting zone has a negative effect to cutting edge. The research purpose is to increase heat transfer in the cutting zone by applying a high-pressure internal cooling system to an external turning tool DCLNR 2525M12 with hope to increase the tool life, and better surface roughness.The standard design ISO tool DCLNR2525M12 has been modified by adding an internal cooling system. This function has 2 types of coolant holes at different positions. The main hole leads to the rake face to increase heat transfer in the cutting zone at the primary shear zone and secondary shear zone, it also improved the chip breakability. The second hole leads to the flank face to increase heat transfer in the cutting zone of the tertiary shear zone.In this study, the shape of the coolant hole is varied to find out the influence of the different shapes of the coolant hole with the same total area. The shape of the coolant hole contains 5 variations to the rake face and 2 variations to the flank face. The two types of holes are combined to study the experiments into 2 groups. Then the samples are analyzed using ANSYS fluid flow (fluent) to find the best hole's combination to reduce heat in the cutting zone.Based on the results of ANSYS Fluid Flow (Fluent) simulation, found 1 sample reduce temperature more than another samples. The sample is SX, reducing the temperature 97.0ºK at inlet 20 m/s.

In the last 15 years, on-line and mobile systems have become major payment instruments for various transactions. The transformation of on- and off-line trade has occurred owing to technological evolution on the Internet, the fast growth of social media, and increased consumer use of mobile devices. The money flow would be still the chief in multitudinous regions, accounting for around 90 percent of all defrayments in several countries of developing. Intrinsically, this is a prominent issue to grasp the crucial determinants of mobile application defrayment acceptance. Additionally, the crucial factors were found in this paper, which affects the adoption of these various types of mobile payments. Through the review of previous studies, we analyzed the development of a consumer behavioral model that explains consumer’s intention and continuance to use mobile payment. The outcome and novelty of this study lie in the formulation of different consumer’s behavior according to the use of consumers to each of the proposed payment tools and skills. The conclusions and implications of this paper with main significances for the explanation, praxis, and management provide alternatives for companies in the future.

There are many pollutants in the air, among which the dust-like objects floating in the air called suspended Particulate Matter (PM). Based on the diameter of the PM, this study makes a distinction in particle sizes smaller than PM2.5 which is the wildfire smoke and particle sizes between PM10~PM100 which is the floating dust and sand in the air. This study uses a reflection multispectral camera which captures information in five spectral bands. Investigation of the photos reveals that the Rededge and NIR bands easily pass through the finer smoke particles. This study believes that the particle size of air pollutants is the decisive factor whether each spectrum can pass through or reflect.
