Modeling and Analysis of Dispersive Propagation of Structural Waves for Vibro-Localization
Authors: Ambarkutuk Murat , Plassmann Paul E.
Published: December 2024

The dispersion of structural waves, where wave speed varies with frequency, introduces significant challenges in accurately localizing occupants in a building based on vibrations caused by their movements. This study presents a novel multi-sensor vibro-localization technique that accounts for dispersion effects, enhancing the accuracy and robustness of occupant localization. The proposed method utilizes a model-based approach to parameterize key propagation phenomena, including wave dispersion and attenuation, which are fitted to observed waveforms. The localization is achieved by maximizing the joint likelihood of the occupant’s location based on sensor measurements. The effectiveness of the proposed technique is validated using two experimental datasets: one from a controlled environment involving an aluminum plate and the other from a building-scale experiment conducted at Goodwin Hall, Virginia Tech. Results for the proposed algorithm demonstrates a significant improvement in localization accuracy compared to benchmark algorithms. Specifically, in the aluminum plate experiments, the proposed technique reduced the average localization precision from 7.77 cm to 1.97 cm, representing a ∼74% improvement. Similarly, in the Goodwin Hall experiments, the average localization error decreased from 0.67 m to 0.3 m, with a ∼55% enhancement in accuracy. These findings indicate that the proposed approach outperforms existing methods in accurately determining occupant locations, even in the presence of dispersive wave propagation.
Non-Myopic Beam Scheduling for Multiple Smart-Target Tracking in Phased Array Radar Networks
Authors: Hao Yuhang , Wang Zengfu , Niño-Mora José , Fu Jing , Pan Quan , Yang Min
Published: December 2024

This paper addresses beam scheduling for tracking multiple smart targets in phased array radar networks, aiming to mitigate the performance degradation in previous myopic scheduling methods and enhance the tracking performance, which is measured by a discounted cost objective related to the tracking error covariance (TEC) of the targets. The scheduling problem is formulated as a restless multi-armed bandit problem, where each bandit process is associated with a target and its TEC states evolve with different transition rules for different actions, i.e., either the target is tracked or not. However, non-linear measurement functions necessitate the inclusion of dynamic state information for updating future multi-step TEC states. To compute the marginal productivity (MP) index, the unscented sampling method is employed to predict dynamic and TEC states. Consequently, an unscented sampling-based MP (US-MP) index policy is proposed for selecting targets to track at each time step, which can be applicable to large networks with a realistic number of targets. Numerical evidence presents that the bandit model with the scalar Kalman filter satisfies sufficient conditions for indexability based upon partial conservation laws and extensive simulations validate the effectiveness of the proposed US-MP policy in practical scenarios with TEC states.

Published: December 2024

Heavy metal pollution, particularly from cadmium (Cd) and copper (Cu), poses significant environmental and health risks. To address the need for efficient, portable, and sensitive detection methods, this study introduces an improved atmospheric pressure glow discharge atomic emission spectrometry (APGD-AES) technique for quantifying Cd and Cu in water samples. The APGD-AES method offers key advantages, including low energy consumption (<33 W), high excitation energy, and compact design. The system was optimized for a discharge voltage of 550 V (Cd) and 570 V (Cu), a flow rate of 3.6 mL/min, and a solution pH of 1.0. Under these conditions, detection limits reached 16 µg/L for Cd and 1.3 µg/L for Cu. APGD-AES was tested on real water samples, including sewage and tap water, demonstrating compliance with national safety standards and comparable performance to graphite furnace atomic absorption spectrometry (GFAAS). This technique shows promise for real-time, on-site monitoring of trace heavy metals due to its portability, precision, and cost-efficiency.

Authors: Chen Zonghao , Liao Xiaohan , Li Shen , Pu Shu , Li Pengfei , He Dingkun , Ye Yizhou , He Xuefeng
Published: December 2024

The wind-induced vibration energy harvester is a type of ideal power source for wireless sensor nodes. To adapt to the uncertainty of wind direction in natural environments, this paper proposes a three-dimensional multi-directional piezoelectric wind energy harvester (WEH), whose bluff body is an external shell with the shape like a lampshade, supported by three internal piezoelectric composite beams. A harvester prototype was made using 3D printing technology, and its multi-directional energy harvesting characteristics were systematically tested in a wind tunnel. Experiments show that it can harvest wind energy from any direction in three-dimensional space. When the wind speed is about 15 m/s and the wind direction changes in the horizontal plane, the minimum to maximum total average output power ratio is about 0.84. This work provides an experimental basis for the future development of three-dimensional multi-directional WEHs to some extent.

Authors: Salgado-Gomes-Sagaz Fabio , Zorrilla-Muñoz Vanessa , Garcia-Aracil Nicolas
Published: December 2024

Recent advancements in patient rehabilitation integrate both traditional and modern techniques to enhance treatment efficacy and accessibility. Hydrotherapy, leveraging water’s physical properties, is crucial for reducing joint stress, alleviating pain, and improving circulation. The rehabilitation of upper limbs benefits from technologies like virtual reality and robotics which, when combined with hydrotherapy, can accelerate recovery. Exoskeletons, which support and enhance movement, have shown promise for patients with neurological conditions or injuries. This study focused on implementing and comparing proportional–integral–derivative (PID) and fuzzy logic controllers (FLCs) in a lower limb exoskeleton. Initial PID control tests revealed instability, leading to a switch to a PI controller for better stability and the development of a fuzzy control system. A hybrid strategy was then applied, using FLC for smooth initial movements and PID for precise tracking, with optimized weighting to improve performance. The combination of PID and fuzzy controllers, with tailored weighting (70% for moderate angles and 100% for extensive movements), enhanced the exoskeleton’s stability and precision. This study also explored quantum computing techniques, such as the quantum approximate optimization algorithm (QAOA) and the quantum Fourier transform (QFT), to optimize controller tuning and improve real-time control, highlighting the potential of these advanced tools in refining rehabilitation devices.
A New Heavy-Duty Bearing Degradation Evaluation Method with Multi-Domain Features
Authors: Xiong Ruolan , Liu Aihua , Xu Dongfang , Qu Chunyang , Wu Yulong
Published: December 2024

Under heavy load conditions, bearings are subjected to non-uniform and frequently changing loads, which leads to randomness in the spatial distribution of bearing degradation characteristics. Aiming at the problem that the traditional degradation index cannot accurately reflect the degradation state of heavy-duty bearings in the whole life cycle, a new degradation evaluation method based on multi-domain features is proposed in this paper, which aims to capture the early degradation point of heavy-duty bearings and characterize their degradation trend. Firstly, the energy entropy feature is obtained by improving the wavelet packet decomposition, and the original multi-domain feature set is constructed by combining the time domain and frequency domain features. Then, the optimal feature matrix is formed by using the comprehensive evaluation index. Finally, integrating probability and distance information, a comprehensive degradation index was constructed to evaluate the degradation, determine the initial degradation time, and quantitatively analyze the bearing degradation state. The validity of the proposed method is verified in two datasets. The proposed method can accurately identify the early degradation of bearings and track the state of bearing degradation, so as to realize the degradation assessment.

Published: December 2024

This article investigates the impact of visual color perception on fine-grained emotion prediction in videos, analyzing the contribution of color perception features in fine-grained emotion prediction. A total of 20 subjects were involved in this experiment. First, 10 subjects conducted a fine-grained emotional subjective evaluation experiment on 50 video clips. Then, another 10 subjects conducted a subjective evaluation experiment of color perception annotation for these 50 video clips. On this basis, the correlation and mechanism between color perceptual features and fine-grained emotions were analyzed. Finally, a fine-grained emotion prediction model was established based on the combination of objective features and color perceptual features. It was also observed that, compared to using only objective features, incorporating perceptual features enhanced the model’s accuracy. This article also compared the importance of different perceptual features for each emotion and explained the mechanism between color perception and fine-grained emotions. By selecting the top 24 important features to predict emotions, the association between perceptual features and emotions was more effectively captured.

Published: December 2024

In recent years, significant research has been conducted on video-based human pose estimation (HPE). While monocular two-dimensional (2D) HPE has been shown to achieve high performance, monocular three-dimensional (3D) HPE poses a more challenging problem. However, since human motion happens in a 3D space, 3D HPE offers a more accurate representation of the human, granting increased usability for complex tasks like analysis of physical exercise. We propose a method based on MediaPipe Pose, 2D HPE on stereo cameras and a fusion algorithm without prior stereo calibration to reconstruct 3D poses, combining the advantages of high accuracy in 2D HPE with the increased usability of 3D coordinates. We evaluate this method on a self-recorded database focused on physical exercise to research what accuracy can be achieved and whether this accuracy is sufficient to recognize errors in exercise performance. We find that our method achieves significantly improved performance compared to monocular 3D HPE (median RMSE of 30.1 compared to 56.3, p-value below 10−6) and can show that the performance is sufficient for error recognition.
Smart and Sustainable Doha? From Urban Brand Identity to Factual Veracity
Authors: Syed Munawer , Aina Yusuf A. , Yigitcanlar Tan
Published: December 2024

Doha, the capital of Qatar, is the country’s administrative, economic, and political hub. With most of Qatar’s population residing in the metropolitan area, Doha effectively functions as a city-state. While the rapid growth of this Gulf metropolis is often celebrated as an emerging center of economic and cultural activity, the subtle yet crucial socio-cultural influences shaping its development as a rentier city-state are frequently overlooked in the existing literature. This research article explores the unique challenges rentier cities like Doha face in becoming truly smart and sustainable. Using a case study approach, the analysis draws from secondary data sources, including city reports, policy documents, and academic studies. By examining publicly available data and Doha’s urban planning history, the article identifies the critical issues and challenges the city faces, particularly following the 2022 FIFA World Cup. It reviews existing planning policies and offers insights into current initiatives and future directions aimed at achieving smart and sustainable development. The findings suggest that while Doha has made considerable progress, more inclusive and comprehensive policies are needed to move beyond entrenched socio-cultural influences and align the city’s growth with its broader sustainability and smart city goals.
A New and Easy Method to Determine the Energy Stored in Urban Areas: A Case Study of Mexico City
Authors: Bonifacio-Bautista Martín , Ballinas Monica , Barradas Victor L.
Published: December 2024

Urban areas present different climates from those of their rural surroundings. Energy balance and especially energy storage play important roles in the resulting climate since more than 50% of the net radiation is absorbed in densely urbanized areas. A simple model of energy storage in the urban fabric is presented, fed with the air temperature of a given area and its thermal properties; it can estimate heat storage (QS) with good results. The proposed QST energy storage model was compared with QS results obtained from two sites in Mexico City, Escandón (objective hysteresis model, QSOHM) and ENP7 (residual, QSRES), and one site in Marseille, France (thermal mass scheme, QSTMS). The comparison between QST and QSOHM showed that r2 = 0.71, while in ENP7 (QN > 0), QSRES and QST were 116.5 Wm−2 and 142 Wm−2, corresponding to 49% and 60% of the QN, respectively. The results obtained using the QSTMS model in Marseille and QST in Escandón showed similar behavior, with RMSEs of 109 and 101 Wm−2, respectively, in a daily period. Although it is difficult to discern which method is better, it is possible to affirm that the presented method is quite accurate, easier to use, and inexpensive.
Castrati singers as a musical and sociocultural phenomenon. Exhumation of Farinelli
Authors:   Department of Art, Moscow University for the Humanities, Zharkova Vasilisa Alekseevna
Published: December 2024

The article is devoted to a rare topic – the art of castrati singers, a vibrant musical and
social phenomenon. This issue remained in the shadows for a long time. However, if
we judge the skill of castrati singers by what their contemporaries described, today's
most excellent vocal performers only barely come close to castrati’s extraordinary capabilities.
It is natural that the best of the best castrati singers, the true stars of the
stage, were called Great then. And we must have maximum information about everything
connected with them. But why Farinelli? Notably, there are people who specialize
in Farinelli studies, and there are quite a lot of them; they form a whole movement
in musicology. Certainly, there are those who study Caff arelli, Tenducci, Vellutti… But
all this remains within the framework of disparate experience, which does not allow us
to talk about Caff arellists, Tenduccists, Veluttists. The article examines a page related to
the history of Farinelli, namely, the story of his exhumation. This is a rare approach to
the analysis of both musical and sociocultural phenomena. Meanwhile, such a turn can
be a vivid illustration of the history of bell canto, and the materials of the article can be
a striking addition to the framework of the courses “History of Vocal Art” and “History
of Foreign Music”.
Intertextuality and interactivity as attributive properties of network creativity
Authors:   Moscow University for the Humanities, Kostina Anna Vladimirovna
Published: December 2024

Intertextuality is a concept of postmodernism, meaning the interrelationship of diff erent
texts. The fi rst idea close to the idea of intertextuality was outlined by M. Bakhtin, who
proved that dialogicity is a property of any statement, but this concept was conceptualized
in the works of Y. Kristeva in the 1960s. Currently, intertextuality is considered as
any of the possible relationships between texts: quotation, allusion, parody, imitation,
etc. Intertextuality, as M. Bakhtin showed, is inherent in any dialogue: between sources
of speech utterance; between people using quotes, hints, and statements that are
recognizable to both; between written sources, where diff erent texts contain similar or
common excerpts, references, and reliance on methodology; between people and texts
when the reader recognizes fragments of other texts in a given text, like an inlay or palimpsest
(text written on a lost original text). Interactivity is the concept of correlation
between subjects or actors of an action, which is expressed in their mutual activity. The
author correlates these concepts with the characteristics of network creativity.
Lebih Cerdas, Lebih Lama Hidup dan Lebih Bahagia: Diskursus Transhumanisme dan Teologi
Authors: Prabowo Agus Agung
Published: December 2024

Transhumanisme sangat optimis jika teknologi akan mampu meningkatkan kualitas hidup manusia, karena itu pemanfaatan teknologi didalam kehidupan manusia harus terus diperluas. Perkembangan terkini, arah perkembangan dan pemanfaatan teknologi sudah mengarah pada integrasi atau penggabungan antara mesin dan manusia. Di satu sisi, perkembangan tersebut menghadirkan harapan besar akan meningkatnya kualitas hidup manusia, tetapi di sisi lain muncul kekuatiran jika hal tersebut justru akan menghancurkan manusia dan kehidupannya. Penelitian dilakukan dengan menggunakan metode kualitatif, pendekatan studi pustaka dan analisis terhadap berbagai literatur mengenai transhumanisme, khususnya Nick Bostrom, Ensiklik Laudato Si' dan literatur terkait lainnya. Kemudian mendialogkannya. Penelitian bertujuan menjawab pertanyaan: bagaimana gagasan transhumanisme untuk meningkatkan kualitas kehidupan manusia melalui pemanfaatan teknologi secara luas harus disikapi. Penelitian menemukan jika keduanya memiliki gagasan yang sama pada upaya peningkatan kualitas hidup manusia. Keduanya mengakui potensi besar teknologi dalam meningkatkan kualitas hidup manusia. Karena itu pengembangan dan penerapan teknologi secara luas bagi peningkatan kualitas hidup manusia perlu disambut dengan baik. Tetapi, Laudato Si' mengkritisi optimisme yang berlebihan Transhumansime terhadap teknologi dan moral manusia.

Spiritualitas Kenosis: Tantangan dan Tuntutan untuk Mewujudkan Gereja Kaum Miskin Di Tengah Budaya Jawa
Authors: Panjaitan Firman , Kusumaningdyah Dwi Ratna
Published: December 2024

Fenomena kemiskinan menjadi masalah yang tidak dapat dihindari oleh gereja, dan gereja pun tidak dapat mengabaikan fenomena ini. Gereja harus merengkuh kemiskinan sehingga menjadi bagian dari kehidupan gereja secara utuh. Hambatan utama perengkuhan gereja terhadap kemiskinan adalah strata sosial masyarakat, khususnya masyarakat Jawa, yang bersifat hierarki. Pembagian kelompok dalam hierarki masyarakat, seringkali memupus habis empati terhadap kemiskinan. Berdasarkan hal ini, tujuan dari penelitian ini adalah membangun sebuah upaya agar gereja dapat merengkuh kemiskinan yang diwujudkan dalam bentuk gereja kaum miskin. Sarana utama dalam merengkuh kemiskinan adalah spiritualitas kenosis (pengosongan diri), yang dihasilkan dari sinergi antara kenosis Yesus Kristus, dalam Injil, dengan kenosis Semar dan Togog, dalam pemahaman budaya Jawa. Dengan menggunakan metode kualitatif, khususnya dengan pendekatan kepustakaan, penelitian ini menghasilkan bahwa gereja kaum miskin dapat dibangun bila gereja memiliki spiritualitas kenosis. Dengan spiritualitas kenosis, gereja bukan hanya merengkuh kemiskinan melainkan juga masuk, melibatkan diri, dan menjadi bagian langsung dari kemiskinan itu, sehingga setiap anggota jemaat yang ada di dalam gereja, meskipun mereka berasal dari latar belakang sosial yang berbeda, hidup dalam pola kesejajaran yang bersifat egaliter.

Published: December 2024

Kasih dan pengampunan seorang ayah dalam perumpamaan anak yang hilang menunjukkan sikap ayah yang penuh kasih dan tanggung jawab terhadap anaknya. Melalui perumpamaan ini tercermin kasih sayang seorang ayah yang tidak hanya terbatas pada kata-kata, tetapi juga tercermin dalam tindakan nyata ketika ia berlari menyambut kembali anak bungsunya yang telah menghabiskan warisan dan hidup dalam kebinasaan. Metode penelitian kualitatif akan mengupas bagaimana karakter seorang ayah yang bertanggung jawab dan penuh kasih terhadap anaknya sebagaimana tertulis dalam Lukas 15:11-32. Dengan demikian, tujuan dari penelitian kiranya menjadi acuan atau role model  dari seorang ayah untuk mengasihi anaknya dengan penuh tanggung jawab. Berdasarkan analisis yang telah dilakukan oleh penulis, maka bukan hanya anak bungsu yang hilang, tetapi juga anak sulung, karena ia tidak merasakan kedekatan emosional dengan ayahnya.

This article presents a literature review on various learning models applied to improve mathematics learning outcomes in integral calculus. The 4 studies that form the basis of the literature study have discussions in understanding integral concepts, critical thinking skills, motivation and learning outcomes and the dimensions of character education. These four studies provide a comprehensive picture of the various approaches that can be used to improve students' understanding and learning outcomes in integral calculus. The first study highlights the effectiveness of the Problem-Based Learning (PBL) model in enhancing students' understanding of integral concepts. The PBL model has been shown to encourage active student engagement and sharpen critical thinking skills. The second study compares two learning models, Discovery Learning and Accelerated Learning, focusing on students' learning motivation and mathematics learning outcomes in integral calculus. The results indicate that Discovery Learning is more effective in improving students' motivation and their deeper understanding of integral concepts. The third study implements Lesson study with a PBL approach that incorporates character education in the class. This approach not only improves mathematical understanding but also develops students' character, such as collaboration and curiosity. Meanwhile, the fourth study develops a learning device for integral calculus based on a problem-solving model to enhance students' creative thinking abilities. These four studies demonstrate that problem-based learning models, whether PBL, Discovery Learning, or problem-solving-based instructional devices, are effective in improving students' understanding and critical thinking skills in integral calculus.

Pasar persaingan sempurna adalah kondisi pasar yang ideal untuk meningkatkan ekonomi masyarakat dan meningkatkan kesejahteraan. Dalam pasar ini, baik pembeli maupun penjual sangat banyak sehingga tidak mungkin untuk menghitung jumlah mereka secara spesifik, memungkinkan hampir semua anggota masyarakat terlibat. Struktur pasar persaingan sempurna dirancang untuk menciptakan iklim perdagangan yang adil dan saling menguntungkan. Dalam sistem ini, terdapat kesepakatan tak tertulis antara pembeli dan penjual untuk menghindari kerugian sepihak. Dengan kata lain, struktur pasar ini dapat dikategorikan sebagai persaingan sempurna dan menawarkan efisiensi yang lebih tinggi dalam proses produksi barang dan jasa dibandingkan dengan jenis pasar persaingan lainnya. Karakteristik utama dari Pasar persaingan sempurna memiliki beberapa karakteristik khas. Pertama, semua perusahaan memproduksi barang yang serupa, sehingga tidak ada perbedaan yang signifikan di antara produk mereka. Kedua, terdapat pengetahuan yang lengkap antara produsen dan konsumen, memungkinkan kedua belah pihak untuk membuat keputusan yang baik berdasarkan informasi yang tersedia. Ketiga, ukuran produksi masing-masing perusahaan relatif kecil jika dibandingkan dengan total output pasar, sehingga tidak ada satu perusahaan pun yang dapat mempengaruhi jumlah barang yang ditawarkan secara keseluruhan. Keempat, perusahaan tidak memiliki kekuatan untuk menentukan harga pasar; harga ditentukan oleh interaksi antara permintaan dan penawaran. Terakhir, perusahaan memiliki kebebasan untuk masuk atau keluar dari pasar tanpa adanya hambatan, yang memungkinkan fleksibilitas dalam menghadapi perubahan kondisi pasar.
