At present, the most common and low-cost method to control the drone is to use a mobile phone with an APP. The operator takes his mobile phone screen as a human-machine interface, and at the same time controls and receives the images returned by the drone. The control mode can be divided into two symmetry modes according to how the operator views and knows the location of the drone: exocentric viewing and egocentric viewing mode. In the exocentric viewing mode, the operator directly visually confirms the position of the drone, while in the egocentric viewing mode, the drone is equipped with a camera and transmits the flight image to the operator in real-time. Since the drone cannot be far away from the operator in the exocentric viewing mode, the relative egocentric mode allows the operator to feel immersed in the environment to control the drone more accurately. Therefore, by adapting the egocentric viewing and using human motion recognition, an unmanned vehicle remote-control system is designed. The low-speed, small-scaled, nature-stability UAVs are ideally suited for the proposed system. The system was designed with a PID controller to improve the UAV's handling. The experimental results verified the feasibility of the UVA control system and it could stabilize the posture of the drone. © 2022 IEEE.

In the cold rolling of flat steel strips, electric energy consumption is one of the highest expenses. Predicting the power requirements according to the line and product conditions can significantly impact the energy cost and, thus, on the business’s profitability. This paper proposes predicting the power requirements of a tandem cold rolling mill of steel strips on a coil-to-coil base applying Artificial Neural Networks (ANN) as a uni-variate regression problem. The tests yielded an MSE of 300.39 kW or 2.4% and are better than the acceptable 5% error margin for this project, indicating that the ANN presented satisfactory results. The application of six full-month worth of data in the trained ANN model showed the excellent correlation of the ANN predictions with the measured data, leading to the conclusion that the system is ready for the deployment for daily use for line engineers. Overall, the results obtained show that the steel industry can highly benefit from Industry 4.0 and Artificial Intelligence technologies. © 2020, Springer Nature Switzerland AG.

The robustness of audio fingerprinting system in a noisy environment is a principal challenge in the area of content-based audio retrieval, especially for use in portable consumer devices. Our new audio fingerprint method using sub-fingerprint masking based on the predominant pitch extraction increases the accuracy of the audio fingerprinting system in a noisy environment dramatically, while requiring much less computing power compared to the expanded hash table lookup method, where the searching complexity increases by the factor of 33 times the degree of expansion.

The labyrinthian fetoplacental capillary network is vital for proper nourishment of the developing embryo. Dysfunction of the maternal-fetal circulation is a primary cause of placental insufficiency. Here, we show that the spatial zonation of the murine placental labyrinth vasculature is controlled by flow-regulated epigenetic mechanisms. Spatiotemporal transcriptomic profiling identified a gradual change in the expression of epigenetic enzymes, including the de novo DNA methyltransferase 3a (DNMT3A). Loss of Dnmt3a resulted in DNA hypomethylation and perturbation of zonated placental gene expression. The resulting global DNA hypomethylation impaired the angiogenic capacity of endothelial cells. Global or endothelium-predominant deletion of Dnmt3a resulted in impaired placental vascularization and fetal growth retardation (FGR). Human placental endothelial gene expression profiling associated preeclampsia with reduced DNMT3A expression. Collectively, our study identified DMNT3A as critical methylome-regulator of placental endothelial gene expression and function with clinical implications for placental dysfunction, as it occurs during preeclampsia or FGR. © 2024 The Authors

Air pollution is a global problem that affects climate stability and human health. It is mainly caused by increasing carbon dioxide $\left(\mathrm{CO}_{2}\right)$ levels. This project aims to lower CO 2 levels using a novel technique that employs green microalgae, specifically Chlorella pyrenoidosa, and an Internet of Things monitor. This experiment combines an MG-811 CO2 sensor and an ESP32 microcontroller to measure CO 2 levels in a controlled setting. In real-time, the ThingSpeak platform receives and processes the sensor data. During the observation period, the average concentration of CO 2 in the system decreased from 707.07 ppm to 677.90 ppm, representing a $\mathbf{3.15 \%}$ drop in CO 2 levels. A statistical study revealed a significant trend indicating a steady drop in CO 2 levels, with a regression coefficient of $\mathbf{-0.000526}$ and a p-value of $7.8975 \times 10^{-6}$. Nevertheless, the data showed inconsistency, with a standard deviation of 81.44 ppm, indicating differences that may be due to the aerator capacity and volume of Chlorella pyrenoidosa used. These results indicate that it is possible to integrate Chlorella pyrenoidosa with Internet of Things technology to reduce CO 2 and manage air quality effectively. This study shows the prospects of this method for scalable and cost-effective environmental solutions, but indicates that further research is needed to improve the performance and adaptability of the system.

This article introduces the concept of synthetic cultures. These are role profiles for enacting dimensions of national culture. The full profiles are given for 10 synthetic cultures, based on Gert Hofstede's dimensions of national culture. They can be used for training or simulation/gaming. Examples of their application are presented. Apart from examples of existing games, suggestions are made for creating custom simulations that use synthetic cultures. Experiences of players are mentioned, both in face-to-face and in electronically mediated settings. Special attention is paid to debriefing issues. The article concludes with practical advice to prospective game leaders. © 1999 Sage Publications, Inc.

TSP cuts which do not conform to the template paradigm 5th

The first computer implementation of the Dantzig-Fulkerson- Johnson cutting-plane method for solving the traveling salesman problem, written by Martin, used subtour inequalities as well as cutting planes of Gomory’s type. The practice of looking for and using cuts that match prescribed templates in conjunction with Gomory cuts was continued in computer codes of Miliotis, Land, and Fleischmann. Gr¨otschel, Padberg, and Hong advocated a different policy, where the template paradigm is the only source of cuts;furthermore, they argued for drawing the templates exclusively from the set of linear inequalities that induce facets of the TSP polytope. These policies were adopted in the work of Crowder and Padberg, in the work of Gr¨otschel and Holland, and in the work of Padberg and Rinaldi;their computer codes produced the most impressive computational TSP successes of the nineteen eighties. Eventually, the template paradigm became the standard frame of reference for cutting planes in the TSP. The purpose of this paper is to describe a technique for finding cuts that disdains all understanding of the TSP polytope and bashes on regardless of all prescribed templates. Combining this technique with the traditional template approach was a crucial step in our solutions of a 13,509-city TSP instance and a 15,112-city TSP instance. © Springer-Verlag Berlin Heidelberg 2001.

We apply the modal distribution, a high-resolution time-frequency distribution, to the study of sung musical passages. Evidence is presented comparing the modal distribution with the spectrogram for a set of synthetic signals which emulate human singing. We then compare the two techniques for sung passages from four student sopranos with respect to measures of the instantaneous frequency and amplitude of the partials. In general, the modal distribution appears to be a more sensitive measure of individual differences in vocal production than the spectrogram. © 1999 Models and Analysis of Vocal Emissions for Biomedical Applications, MAVEBA 1999.
