The paper presents a performance analysis of a digital underwater acoustic communication system for operating distances above 300 km in 300-500 Hz bandwidth. Estimating the system's performance relies on the underwater acoustic channel model involving a rapid transition from shelf zone to deep-sea consisting of ray patterns and channel impulse responses. Reverberation in such conditions of 200-600 ms imposes specific design requirements to an efficient digital system of commands and data transmission in such a narrow band. The bitrate of 20 bit/s was achieved for stated distances under severe multipathing.

The development of science and technology and the innovation of network technology enable big data technology. In the pandemic of coronary pneumonia in 2020, complex and large scale epidemic data, data analysis, and processing play an important role. Data visualization shows the advantages of rapid processing and intuitive display of data analysis, which helps people accurately and objectively predict the direction of the epidemic. This paper aims to create display pages on the front end of the epidemic data website with HTML, CSS, and JavaScript. The Flask framework of python is used to build a server to process the data on the back end. At the same time, ECharts is used to visualize and analyze the data, which finally displays the status and trend of the epidemic in each region in real-time.

Many sleep problems have occurred due to changes in the modern lifestyle. Insomnia is more serious than other sleep disorders. Insomnia increases the risk of depression, obesity, and cardiovascular diseases when it is not treated properly. Nowadays, most sleep therapies involve drugs that cause side effects on. For non-drug therapies, certain sounds assist sleep. However, as the sound is subjective, it is difficult to determine the sound suitable for each individual. This research designs an application that recommends white noise to insomniacs. For the application, we use machine learning technology for white noise recommendation and the design method for the user interface. For the experiment, we conduct a randomized controlled experiment and a five-day sleep experiment. This experiment verifies the effectiveness of the recommended white noise for sleep improvement. In addition to sleep assessment, we also use the system usability scale and semi-structured interviews to validate this system’s usability and willingness. The result shows that white noise improves deep sleep and reduces the time to fall asleep. Moreover, the usability score of this application is much higher than the passing score of the scale.

Gate drivers are extensively used in many applications such as DC to AC inverters, switch controlling of battery charging, and AC to AC converters. All require a gate signal to drive the MOSFET. However, traditional drivers use optically coupling components to achieve a high level of isolation, which creates disadvantages like power consumption, large size, and low integration levels. Thus, this paper proposes a different solution that uses an on-chip transformer to provide power isolation instead of an optically coupling component. Moreover, the oscillator, transformer, rectifier, and data buffer can all be integrated into a single chip. In other words, the size of the driver can be reduced and its integration level can be increased. When compared with the traditional design, this circuit does not use the discrete solution method for power isolation, so it is not susceptible to external noise interference.

In this paper we present a software system to simulate manufacturing in a real-time remote manner. The system contains real-time communication and simulation models. People who work on designing a production line can use this system to simulate the interaction between robots and other machines, observe and control the robots in the factory, prevent or reduce the severity of a collision. In summary, our system can not only improve the working efficiency and security but also keep the cost down.In the process of implementing our models, we proposed several methods to overcome some technical problems and to improve the performance. In the communication model, two proposed methods: messaging server (MS) and database semaphore, will be used to handle the peer-to-peer (P2P) connections and the real-time controlling. We also introduce the parallel programming and the general purpose GPU (GPGPU) into the simulation. In order to speed up the computation and the object drawing, all these methods make our system more precise, stable and faster than other approaches.Finally, we test and verify our system in the actual use, by simulating the real robots and connecting to the controllers in the real environment; the result shows our system is robust, fast and trustworthy in real-world use of smart manufacturing.

This paper proposes the machining time optimization and surface quality improvement based on a digital twin model of machine tools. This model considers servo loops, feed drive system, and tool center point (TCP) effects which were constructed simultaneously. The frequency response of the actual machine was excited by a swept sinusoidal waveform then the digital twin model was identified. Finally, the parameters of controller tuned on digital twin model to achieve the optimizing machining time and decrease the oscillation of TCP.

N-doping TiO2-SiO2 nanofilm on glass has been successfully produced via the sol-gel dip-coating technique and modified by a rapid microwave plasma-nitridation process at 1200 W for 1 min. The film properties are simultaneously reaching the high transmittance of film/glass (> 90%), high hardness (8H), and high adhesion (5B). Moreover, the self-cleaning and anti-fogging applications of the film/glass can be easily achieved by visible photo-induced superhydrophilicity and photocatalysis for application within in weak or nonexistent UV light irradiation environments.

According to the NHTSA, an average of 384 fatalities occur annually in the United States due to drowning while driving. The California wildfires in 2017 caused a property loss of $13 billion, 46 lives, and injuries to hundreds more. Most of the current alerting mechanisms are expensive and deficient in features for detecting floods at road crossings, wildfires, and air quality. The current fire alerting systems cost thousands of dollars, but they are not multi-purpose and compatible with smart city infrastructure. Also, the current flood alerting systems cost tens of thousands of dollars, are radio frequency-based, and require large antennas, but only provide a limited range. This paper proposes an innovative system, Cerberus, to provide early warnings for fires, floods, and air quality using an IoT device, sensors, cloud, and mobile technologies. The solution provides a Red-Yellow-Green light system for local alerts and a mobile app to alert users about unsafe water levels, fire, and air quality. All the data collected by Cerberus is stored in the cloud and used for other types of alerts such as voice calls, text alerts, and emails. The Cerberus warning system is low-cost, accurate, easy to maintain, and scalable to thousands of locations. The warning system is also integrated with an analytics platform that shows trends and historical data. The prototype was validated in the field using real data. The results show that Cerberus is a viable solution for providing accurate and reliable alerts for floods, wildfires, and air quality.
