A Robotics Experimental Design Method Based on PDCA: A Case Study of Wall-Following Robots
Authors: Wong Kai-Yi , Pu Shuai-Cheng , Wong Ching-Chang
Published: March 2024

There is a lack of research that proposes a complete and interoperable robotics experimental design method to improve students’ learning outcomes. Therefore, this study proposes a student-oriented method based on the plan-do-check-act (PDCA) concept to design robotics experiments. The proposed method is based on our teaching experience and multiple practical experiences of allowing students to do hands-on experiments. It consists of eight steps, mainly including experimental goals, experimental activities, robot assembly, robot control, in-class evaluation criteria, and after-class report requirements. The after-class report requirements designed in the proposed method can help students improve their report-writing abilities. A wall-following robotics experiment designed using the PDCA method is proposed, and some students’ learning outcomes and after-class reports in this experiment are presented to illustrate the effectiveness of the proposed method. This experiment also helps students to understand the fundamental application of multi-sensor fusion technology in designing an autonomous mobile robot. We can see that the proposed reference examples allow students to quickly assemble two-wheeled mobile robots with four different sensors and to design programs to control these assembled robots. In addition, the proposed in-class evaluation criteria stimulate students’ creativity in assembling different wall-following robots or designing different programs to achieve this experiment. We present the learning outcomes of three stages of the wall-following robotics experiment. Three groups of 42, 37, and 44 students participated in the experiment in these three stages, respectively. The ratios of the time required for the robots designed by students to complete the wall-following experiment, less than that of the teaching example, are 3/42 = 7.14%, 26/37 = 70.27%, and 44/44 = 100%, respectively. From the comparison of learning outcomes in the three stages, it can be seen that the proposed PDCA-based design method can indeed improve students’ learning outcomes and stimulate their active learning and creativity.
Deep Learning for Gas Sensing via Infrared Spectroscopy

Published: March 2024

Deep learning methods, a powerful form of artificial intelligence, have been applied in a number of spectroscopy and gas sensing applications. However, the speciation of multi-component gas mixtures from infrared (IR) absorption spectra using deep learning remains to be explored. Here, we propose a one-dimensional deep convolutional neural network gas classification model for the identification of small molecules of interest based on IR absorption spectra in flexible user-defined frequency ranges. The molecules considered include ten that are of interest in the atmosphere or in industrial and environmental processes: water vapor, carbon dioxide, ozone, nitrous oxide, carbon monoxide, methane, nitric oxide, sulfur dioxide, nitrogen dioxide, and ammonia. A simulated dataset of IR absorption spectra for mixtures of these molecules diluted in air was generated and used to train a deep learning model. The model was tested against simulated spectra containing noise and was found to provide speciation predictions with accuracy from 82 to 97%. The internal operation of the model was investigated using class activation maps that illustrate how the model prioritizes spectral information for classification. Finally, the model was demonstrated for the prediction of speciation for two synthetic experimental mixture spectra. The proposed model and the dataset generation strategies are generalized and can be implemented for other gases, different frequency ranges, and spectroscopy types. The multi-component speciation method developed herein is the first application of a convolutional neural network model, trained on HITRAN-based simulations, for spectral identification.
Principal Component Analysis Enhanced with Bootstrapped Confidence Interval for the Classification of Parkinsonian Patients Using Gaussian Mixture Model and Gait Initiation Parameters

Published: March 2024

Parkinson’s disease is one of the major neurodegenerative diseases that affects the postural stability of patients, especially during gait initiation. There is actually an increasing demand for the development of new non-pharmacological tools that can easily classify healthy/affected patients as well as the degree of evolution of the disease. The experimental characterization of gait initiation (GI) is usually done through the simultaneous acquisition of about 20 variables, resulting in very large datasets. Dimension reduction tools are therefore suitable, considering the complexity of the physiological processes involved. The principal Component Analysis (PCA) is very powerful at reducing the dimensionality of large datasets and emphasizing correlations between variables. In this paper, the Principal Component Analysis (PCA) was enhanced with bootstrapping and applied to the study of the GI to identify the 3 majors sets of variables influencing the postural control disability of Parkinsonian patients during GI. We show that the combination of these methods can lead to a significant improvement in the unsupervised classification of healthy/affected patients using a Gaussian mixture model, since it leads to a reduced confidence interval on the estimated parameters. The benefits of this method for the identification and study of the efficiency of potential treatments is not addressed in this paper but could be addressed in future works.

Repeated single-point measurements of thoracic bioimpedance at a single (low) frequency are strongly related to fluid changes during hemodialysis. Extension to semi-continuous measurements may provide longitudinal details in the time pattern of the bioimpedance signal, and multi-frequency measurements may add in-depth information on the distribution between intra- and extracellular fluid. This study aimed to investigate the feasibility of semi-continuous multi-frequency thoracic bioimpedance measurements by a wearable device in hemodialysis patients. Therefore, thoracic bioimpedance was recorded semi-continuously (i.e., every ten minutes) at nine frequencies (8–160 kHz) in 68 patients during two consecutive hemodialysis sessions, complemented by a single-point measurement at home in-between both sessions. On average, the resistance signals increased during both hemodialysis sessions and decreased during the interdialytic interval. The increase during dialysis was larger at 8 kHz (∆ 32.6 Ω during session 1 and ∆ 10 Ω during session 2), compared to 160 kHz (∆ 29.5 Ω during session 1 and ∆ 5.1 Ω during session 2). Whereas the resistance at 8 kHz showed a linear time pattern, the evolution of the resistance at 160 kHz was significantly different (p < 0.0001). Measuring bioimpedance semi-continuously and with a multi-frequency current is a major step forward in the understanding of fluid dynamics in hemodialysis patients. This study paves the road towards remote fluid monitoring.

Published: March 2024

A new scheme presents MEMS-based LiDAR with synchronized dual-laser beams for detection range enhancement and precise point-cloud data without using higher laser power. The novel MEMS-based LiDAR module uses the principal laser light to build point-cloud data. In addition, an auxiliary laser light amplifies the single-noise ratio to enhance the detection range. This LiDAR module exhibits the field of view (FOV), angular resolution, and maximum detection distance of 45° (H) × 25° (V), 0.11° (H) × 0.11° (V), and 124 m, respectively. The maximum detection distance is enhanced by 16% from 107 m to 124 m with a laser power of 1 W and an additional auxiliary laser power of 0.355 W. Furthermore, the simulation results show that the maximum detection distance can be up to 300 m with laser power of 8 W and only 6 W if the auxiliary laser light of 2.84 W is used, which is 35.5% of the laser power. This result indicates that the synchronized dual-laser beams can achieve long detection distance and reduce laser power 30%, hence saving on the overall laser system costs. Therefore, the proposed LiDAR module can be applied for a long detection range in autonomous vehicles without requiring higher laser power if it utilizes an auxiliary laser light.
Distributed Real-Time Feedback Optimization for Renewable Energy Sources and Vehicle-to-Grid Power Compensation of Electric Vehicle Chargers in Distribution Systems
Authors: Cheng Y. , Ching T. W.
Published: March 2024

A novel distributed feedback optimization-based controller for electric vehicle (EV) chargers and renewable energy sources (RESs) in distribution systems is proposed. The proposed controller utilizes the flexibility in EV chargers’ active and reactive power consumption to offer the desirable vehicle-to-grid services. Instead of using the conventional cascaded PI controllers, a new optimization-based approach is proposed to control RESs to track their power injection setpoints. The proposed controller formulates the control targets as a single constrained optimization problem, i.e., to minimize the critical bus voltage magnitude deviations while driving RESs to follow their power setpoints, thereby fulfilling the EV charging requirements and regulating their power outputs and bus voltage magnitudes to stay within their limits. A distributed feedback optimization-based control algorithm is designed for EV chargers and RESs to steer the system trajectories of the distribution systems towards the optimal solution of the formulated optimization problem. Simulation results show that the proposed controller can always steer the test system to the optimal solution of the optimization problem. The advantages of the real-time vehicle-to-grid power compensation of EV chargers are also demonstrated.

Treatment efficacy and early complications of Percutaneous Transhepatic Holmium Laser Lithotripsy for biliary stones under Digital Subtraction Angiography guidance
Authors: Le Tuan Linh , Nguyen Thai Binh
Published: March 2024

Background: Intrahepatic stones and common bile duct stones are common diseases in Vietnam. Surgical treatments have a high rate of remaining intrahepatic bile duct stones and are ineffective with intrahepatic stones and cases with biliary strictures, while endoscopic retrograde cholangiopancreatography stone removal (ERCP) is usually indicated for small common bile duct stones and has disadvantages such as having to performe sphincterectomie of Oddi, 5% causing acute pancreatitis. Nowadays, minimally invasive treatment techniques are more and more developed. Percutaneous transhepatic lithotripsy under fluoroscopy guidance (TSQD) is an improved method using Holmium laser with small sized trocart (16F) help avoid open surgery and increase the rate of stone clearance, especially with stones located in the intrahepatic duct branches. For that reason, we conducted research to evaluate the treatment effectiveness and early complications of this method.

Materials and method: This study was conducted on a group of 38 patients with main biliary tract stones, diagnosed and treated using PTHLL under fluoroscopy guidance at Hanoi Medical University Hospital from July 2018 to December 2019.

Results: The PTHLL procedures was performed on patients with main extrahepatic biliary stones (28.9%) and those with intrahepatic stones, either isolated or combined (71.1%). One-step lithotripsy was applied in 26.3% of cases without cholangitis, simple stones. In another hand, Two-steps procedure were indicated in 73.7% of cases with cholangitis, multiple stones, and poor patient health. Stand-alone laser lithotripsy (23.7%) was suitable for simpler cases, while combination with baskets and balloons (76.3%) was used for complex situations. The overall complete stone clearance rate was 84.2%. Complications included septicemie (7.8%) and biloma (2.6%). No major complications like bleeding or deaths were encountered in this study.

Conclusion: PTHLL under fluoroscopy guidance is a minimally invasive method that achieves a high rate of complete stone clearance in both intra- and extrahepatic biliary stones, with a low early complication rate.

Cancer causes death in all countries of the world, with approximately (9.6) million deaths in 2018. Developing countries have high cancer rates. Furthermore, there are risk factors that lead to cancer, including economic and political instability and bad lifestyles. This is the first study of PSCA gene expression with BC, CRC and PC in Iraq, especially in Basrah governorate. This paper involved one hundred and one blood samples being collected from bladder, colorectal and prostate cancer. On the other hand, one hundred and one blood samples with no cancer were collected as a control group. Two ml of peripheral blood was drawn for RNA extraction, then total RNA was reverse transcribed to cDNA, and PSCA mRNA was measured using qPCR. The results showed PSCA gene was over expressed in bladder cancer (BC) with an expression level at ± 8.63 for patients and controls estimated with ±4.16. The gene expression was a 2-fold change in patients compared to healthy control. While the PSCA gene was over-expressed in colorectal cancer (CRC) with an expression level ± 8.16 for patients and controls estimated at ±3.30. That means the gene expression was a 2.47-fold change in patients compared to healthy control. The PSCA gene was over expressed in prostate cancer (PC) with an expression level ± 9.47 for patients and controls estimated at ±4.22. The gene expression was a 2.24-fold change in patients compared to healthy control. In the present study, PSCA gene was expressed at a significantly higher level in the BC, CRC and PC patients compared in the controls group.

Making a decision about which project is the most profitable is not an easy task, especially when it comesto investments that require large investments. In practice, there are a large number of methods that are applied in order tomake the right decision. The aim of this paper is to show, through empirical analysis, the application of AHP and PROMETHEEmethods as extremely effective when deciding on the best alternative location for the construction of a mini-hydroelectric powerplant. In order to demonstrate the application of these methods and the process of choosing the most profitable project, usingthese methods, real data obtained by the investor, who has three alternative locations for the construction of a mini-hydroelectricpower plant, was used. First, an adequate discount factor, calculated net present value, Internal rate of RETURN project anddynamic investment payback period were selected, in order to then apply the AHP calculation, and then the PROMETHEEmethod in the Decision Lab 2000 program, based on all previously calculated indicators. The combination of these methodsshowed which of the projects is the most profitable and which should be implemented. The very application of these methodsalso showed us that several methods should be used before the final decision is made, in order to choose the most profitablealternative for the investor.

Education is a requirement for the development and existence of every modern state. This paper will discuss the structure of school systems in the German province of Bavaria and the Republic of Srpska for the level of primary and secondary education. What possible options are available to students aged six to nineteen can be seen in the schematic representations of the Bavarian school system and the same in the Republic of Srpska (Bosnia and Herzegovina). Knowing that the economic progress of the country is also reflected in the education of the young generation, the organization of education should be one of the key issues of the government of each country. Comparing the similarities and differences of our school system with the system of other countries, we encourage those in charge to constantly revise the existing system, thereby contributing to reducing its deficiencies and improving teaching practice, and thus the quality of education. In this regard, it is always good to follow trends in the development of school systems in economically developed countries. The teaching organization system is similar, but at the same time different in each country. This can also be seen in the conclusions of this paper. The Western countries school models, especially SR Germany, attract the public attention due to the outflow of the population of the Republic of Srpska to those countries. If we want to prevent or reduce this phenomenon, we must become attractive to our own population and be competitive on the market. This paper points to the need for constant monitoring and modification of the existing school system, as well as its adaptation to global trends. Given that the Balkan countries are ranked far worse than the Western Europe countries in international tests, it would be interesting to deal with the school systems of the Scandinavian countries in some future work.

The paper analyzes the texts of Danica Krstić (1873–1966) in the magazine Muzički glasnik, published in 1922 in Belgrade. Danica Krstić is known to the professional public as one of the first piano teachers at the Serbian Music School (from 1903 to 1940) and as the author of the first piano textbook in the Serbian language, Piano School (1911). However, few people know the fact that she was also a music critic in the magazine Muzički glasnik. Namely, she gave two critical reviews of the concerts of young pianists - Ćiril Ličar and Vera Lotar. In both articles, the author used the same method - it is an analytical presentation of the works that are in the repertoire, while the emphasis is on the performing skills of the mentioned artists. This fact is not surprising, given that the author was professionally oriented towards performing. The paper will also discuss the historical development and importance of music criticism in Serbia in the period between the two World Wars. The historical processes through which music criticism in our region went through, as well as the methods of changes in the critical model in the period between the two World Wars, will be pointed out. It will also be discussed about the magazine Muzički glasnik in the context of selected articles, but also the entire magazine as one of the most important in the domestic area in the mentioned time frame. The goal is to highlight the diverse professional involvement of Danica Krstić and her role in the process of developing musical culture and education in Belgrade and Serbia at the beginning of the 20th century. The paper uses the method of theoretical analysis as well as an analytical-musicological view of the concert life of the Serbian capital.

The role of dance as a transformative medium for women’s emancipation, tracing its evolution from the Renaissance period to contemporary times. is a topic that necessitates a broad, multidisciplinary analysis. Dance is presented not only as a form of artistic expression but also as a powerful instrument for social change and gender equality. Through historical analysis, the study highlights how dance has facilitated women’s ability to express their identities, challenge patriarchal norms, and advocate for their rights across various epochs. The research underscores significant contributions by key figures and movements that have used dance as a platform for signalling shifts in societal attitudes towards women’s roles and freedoms. By drawing on the works of scholars such as Goldman (2010) on improvisational dance, Hahn (2013) on the role of creative arts in education and social change, Camp (2002) on dance as a form of resistance among enslaved women, and Åhäll (2016) on feminist security studies, the paper elucidates dance’s multifaceted impact on women’s liberation. From the sophisticated court dances of the Renaissance that reflected societal and cultural shifts to the expressive and boundary-pushing performances of the 19th and 20th centuries, dance emerged as a dynamic force in advocating for women’s emancipation. The conclusion reaffirms dance’s ongoing relevance as a medium through which contemporary women continue to explore their identities, challenge existing norms, and promote feminist values, thereby contributing to the broader discourse on gender equality and empowerment.

The managerial triad of the modern era consists of communication, leadership, and coordination; therefore, communication emerges as an imperative when studying management. Communication is a complex process and represents one of the fundamental competencies of successful individuals. The functioning of each part of an organization is largely conditioned by the nature and system of the communication process. There is a very close connection between the management process and communication activities. It is of paramount importance that there are good communications within the organization, as well as between the organization and its environment, enabling the organization to act as a unified entity directed towards common goals. The effectiveness of communication is of great significance because communication is a condition for directing and influencing employees towards achieving organizational interests, implementing changes, and generating good ideas. Adapting to a turbulent environment requires continuous development and improvement, which is a prerequisite for successful communication in the management process. The goal of this paper is to highlight the role and importance of communication and negotiation for successful business operations.
