Published: August 2024

In this paper, we present a cost-effective system for monitoring and controlling alkaline electrolyzers, intending to improve hydrogen gas production on a laboratory scale. Our work includes two main innovations. Firstly, we suggest an approach to calibrate a standard air flow meter to accurately measure the flow of hydrogen-rich gas from electrolyzers, improving measurement accuracy while keeping costs low. Secondly, we introduce a unique cascade control method to manage hydrogen-rich gas production in the electrolyzer, ensuring precise control over gas flow rates. By combining affordable, energy-efficient devices with a PI control system, we achieve efficient gas production through electrolysis, replacing manual control approaches. Experimental results confirm the effectiveness of our cascade control method, demonstrating stable operation with minimal errors. These results provide a foundation for further research into control strategies to enhance the performance of electrolytic cells.
Smart Spare Parts (SSP) in the Context of Industry 4.0: A Systematic Review
Authors: Morales Pavez G. , Durán Orlando
Published: August 2024

The implementation of Industry 4.0 has integrated manufacturing, electronics, and engineering materials, leading to the creation of smart parts (SPs) that provide information on production system conditions. However, SP development faces challenges due to limitations in manufacturing processes and integrating electronic components. This systematic review synthesizes scientific articles on SP fabrication using additive manufacturing (AM), identifying the advantages and disadvantages of AM techniques in SP production and distinguishing between SPs and smart spare parts (SSPs). The methodology involves establishing a reference framework, formulating SP-related questions, and applying inclusion criteria and keywords, initially resulting in 1603 articles. After applying exclusion criteria, 70 articles remained. The results show that while SP development is advancing, widespread application of AM-manufactured SP is recent. SPs can anticipate production system failures, minimize design artifacts, and reduce manufacturing costs. Furthermore, the review highlights that SSPs, a subcategory of SPs, primarily differs by replacing conventional critical parts in the industry, offering enhanced functionality and reliability in industrial applications. The study concludes that continued research and development in this field is essential for further advancements and broader adoption of these technologies.
Human Multi-Activities Classification Using mmWave Radar: Feature Fusion in Time-Domain and PCANet
Authors: Lin Yier , Li Haobo , Faccio Daniele
Published: August 2024

This study introduces an innovative approach by incorporating statistical offset features, range profiles, time–frequency analyses, and azimuth–range–time characteristics to effectively identify various human daily activities. Our technique utilizes nine feature vectors consisting of six statistical offset features and three principal component analysis network (PCANet) fusion attributes. These statistical offset features are derived from combined elevation and azimuth data, considering their spatial angle relationships. The fusion attributes are generated through concurrent 1D networks using CNN-BiLSTM. The process begins with the temporal fusion of 3D range–azimuth–time data, followed by PCANet integration. Subsequently, a conventional classification model is employed to categorize a range of actions. Our methodology was tested with 21,000 samples across fourteen categories of human daily activities, demonstrating the effectiveness of our proposed solution. The experimental outcomes highlight the superior robustness of our method, particularly when using the Margenau–Hill Spectrogram for time–frequency analysis. When employing a random forest classifier, our approach outperformed other classifiers in terms of classification efficacy, achieving an average sensitivity, precision, F1, specificity, and accuracy of 98.25%, 98.25%, 98.25%, 99.87%, and 99.75%, respectively.

Authors: Yoon Namkyung , Kim Kiseok , Lee Sangmin , Bai Jin Hyoung , Kim Hwangnam
Published: August 2024

Drones have become essential tools across various industries due to their ability to provide real-time data and perform automated tasks. However, integrating multiple sensors on a single drone poses challenges such as payload limitations and data management issues. This paper proposes a comprehensive system that leverages advanced deep learning techniques, specifically an attention-based generative adversarial network (GAN), to address data scarcity in drone-collected time-series sensor data. By adjusting sensing frequency based on operational conditions while maintaining data resolution, our system ensures consistent and high-quality data collection. The spatiotemporal The attention mechanism within the GAN enhances the generation of synthetic data, filling gaps caused by reduced sensing frequency with realistic data. This approach improves the efficiency and performance of various applications, such as precision agriculture, environmental monitoring, and surveillance. The experimental results demonstrated the effectiveness of our methodology in extending the operational range and duration of drones and providing reliable augmented data utilizing a variety of evaluation metrics. Furthermore, the superior performance of the proposed system was verified by comparing it with various comparative GAN models.
A Gradient Dynamics-Based Singularity Avoidance Method for Backstepping Control of Underactuated TORA Systems
Authors: Pan Changzhong , Pu Hongsen , Li Zhijing , Xiao Jinsen
Published: August 2024

In this paper, a gradient dynamics-based control method is proposed to directly tackle the singularity problem in the backstepping control design of the TORA system. This method is founded upon the construction of an energy-like positive function, which includes an auxiliary variable in terms of the intermediate virtual control law. On this basis, a gradient dynamics is created to obtain a new virtual control command, which is capable of making the auxiliary variable gradually approach zero, thereby mitigating the issue of division by zero. The core innovation is the integration of the gradient dynamics into the recursive backstepping design to overcome the singularity problem and stabilize the system at the equilibrium quickly. In addition, it rigorously proves that all the signals in the closed-loop control system are uniformly ultimately bounded, and the tracking errors converge to a small neighborhood around zero through a Lyapunov-based stability analysis. Comparative simulations demonstrate that the proposed approach not only avoids the singularity issue, but also achieves a better transient performance over other methods.
A New Method Based on Locally Optimal Step Length in Accelerated Gradient Descent for Quantum State Tomography
Authors: Dolatabadi Mohammad , Loia Vincenzo , Siano Pierluigi
Published: August 2024

Quantum state tomography (QST) is one of the key steps in determining the state of the quantum system, which is essential for understanding and controlling it. With statistical data from measurements and Positive Operator-Valued Measures (POVMs), the goal of QST is to find a density operator that best fits the measurement data. Several optimization-based methods have been proposed for QST, and one of the most successful approaches is based on Accelerated Gradient Descent (AGD) with fixed step length. While AGD with fixed step size is easy to implement, it is computationally inefficient when the computational time required to calculate the gradient is high. In this paper, we propose a new optimal method for step-length adaptation, which results in a much faster version of AGD for QST. Numerical results confirm that the proposed method is much more time-efficient than other similar methods due to the optimized step size.
Effect of Weighted Vest at 0%, 5% and 10% of Body Mass on Gasometry Biomarkers and Performance during a Rectangular Test in Trained Trail Runners
Authors: Martínez-Noguera Francisco Javier , Alcaraz Pedro E. , Marín-Pagán Cristian
Published: August 2024

Trail runners (TRs) must carry an extra load of equipment, food (bars and gels) and liquids, to delay the anticipation of fatigue and dehydration during their competitions. Therefore, we aimed to evaluate how an extra load can influence the metabolic level. Thirteen well-trained trail runners performed a randomized crossover study (total n = 39), completing three treadmill running sessions with a weighted vest of 0%, 5% and 10% of their body mass during a combined test (rectangular test + ramp test). In addition, biomarkers of oxygen metabolism, acid–base and electrolyte status pre-, during and post-test, as well as the rectangular from capillary blood of the finger and time to exhaustion, were analyzed. Repeated-measures ANOVA showed no significant difference between conditions for any of the analyzed biomarkers of blood gas. However, one-way ANOVA showed a significant difference in trial duration between conditions (p ≤ 0.001). Tukey’s post hoc analysis observed a significant decrease in time to exhaustion in the weighted vest of 10% compared to 0% (p ≤ 0.001) and 5% (p ≤ 0.01) and 5% compared to 0% (p = 0.030). In addition, repeated-measures ANOVA detected a significant difference in pH in the group x time interaction (p = 0.035). Our results show that increasing the weighted vest (5% and 10%) anticipates fatigue in runners trained in TR. In addition, increasing the load decreased pH by a smaller magnitude at 10% compared to 0% and 5% at the end of the exercise protocol.

RENEWAL OF ISLAMIC THOUGHT
Authors: Sajadi Darun
Published: August 2024

There are two factors that create the issue of renewal in Islam, precisely the renewal of understanding of Islam, both actual and controversial throughout the history of Islamic thought. Both of these factors are intrinsic, inherent in Islam itself, and therefore can be seen as the character of Islam.
First, the Islamic universal character. This character requires a new understanding to respond to the ever-changing development of human life. Universal Islam, in the sense that it is suitable for all space and time (shâlih li-kulli zamân wa makân), demands the actualization of Islamic values in the context of cultural dynamics. This contextualization is an attempt to discover the relationship between the Islamic nature and the spirit of the times. The essence of Islam, the dignity and universality, are related to the spirit of times; which is a tendency to renewal and progress. The achievement of the ideals benefit for all really depends on new discoveries of methods and techniques for a better and more advanced life.
Second, the absoluteness of Islamic character. That is as a religion that is believed by its followers as absolute truth. This belief has the implication that Islam is a system that solves other systems, and even Islam is the only valid system while the other is inappropriate. These two characteristics of Islam, universality and absoluteness, each have their basis in the Holy Qur’an. Renewal in Islam is actually a rationalization of Islamic understanding and contextualization of Islamic values into life. Rationalization implies an effort to find the substance and removal of symbols. Whereas contextualization implies an effort to correlate the substance with a specific socio-cultural platform and the possibility of using these cultural symbols to repackage the substance itself.
Rationalization and contextualization can be referred to as the process of interpretation of Islam into the cultural process, and the allocation of these values into new cultures. Renewal in Islam involves a substantive approach (emphasizing content) on Islam. This is what distinguishes between reformers and their critics who tend to maintain a formalistic approach in understanding and applying Islamic theory.

Authors: Ceyhan Akça Nesime
Published: August 2024

Tarihte bazı kırılma anları vardır ve bunlar devletlerin/ulusların geleceklerinin şekillenmesine etki eder. Türkler ve Anzaklar açısından Çanakkale savaşları işte bu kırılma noktalarından biri olarak kabul edilebilir. Çanakkale kara ve deniz savaşlarında Türk ordusunun İtilaf devletleri karşısında gösterdiği destansı mücadele Türkiye Cumhuriyeti’nin kuruluşuna giden yoldaki önemli kilometre taşlarından biridir. İngiliz ve müttefik ordularının 25 Nisan 1915’te gerçekleştirdikleri Anzak çıkarmasında en önde yer alan Avustralya askerleri savaşta çok zayiat vermeleri ve galip gelememelerine rağmen Anzak çıkarması Avustralya’da da ulus bilincinin oluşmasının başlangıcı olarak görülür. Bu çalışmanın amacı Gelibolu yarımadasında gerçekleşen Anzak çıkarmasına katılmış Avustralyalı asker/şair Francis Edmund Westbrook’un şiirlerinde Gelibolu muharebelerinin izini sürmek, şairin Türk askerleri hakkındaki düşüncelerini öğrenmek ve savaşta ölen silah arkadaşıyla içten içe gerçekleşen hesaplaşmasını irdelemektir. Çalışmada ele alınan Good-Bye ve Fame başlıklı iki şiir F. E. Westbrook’un 1916 yılında yayımlanan Anzak and After (Anzak ve Sonrası) adlı şiir kitabında yer almaktadır. Şiirler analiz edilirken tarihsel analiz ve metin/içerik analiz yöntemleri kullanılmıştır. Çalışmada ileri-geri bağlantılar kurularak Gelibolu muharebesine katılan Avustralyalı askerin gözünden Anzak askerlerinin ruh halleri, savaşta karşılaştıkları zorluklar, savaşta başarı elde edemeyiş sebepleri ve savaş sonrasında kendilerini ülkelerinde bekleyen sonucun ne olduğu öğrenilmeye çalışılmıştır.

Published: August 2024

This article describes the experiences and reflections of women activists in facing the challenges of advocating for the issue of sexual violence and the implementation of Anti Sexual Violence Law (UU TPKS) at the community level. A qualitative research method with a feminist perspective was deployed and thus data collection was conducted through interviews with women activists from different regions such as Aceh, Flores, Banjarmasin, Semarang and Yogyakarta. This study develops the perspectives of sociology of law and feminism to understand the extent to which internal and external aspects influence the implementation of the TPKS Law in the community including gender issues in it. The study results show that the implementation of UU TPKS needs to be seen as a complex and non-linear process due to the challenges of legal plurality reflected by the diversity of customary/local laws in a number of communities in Indonesia. Thus, special efforts are needed that not only focus on the provision of legal products, but also on how the legal products, such as UU TPKS, could be seen as inputs that have targets on the transformation of legal culture to the community level.

Kegiatan ini didasari oleh adanya keinginan untuk berbagi ilmu dan pengalaman dengan guru di SDN No.111 Inpres Lassang 1 Takalar. Melalui praktik mendemonstrasikan pengetahuan atau skill tentang cara menentukan volume kubus dan balok, penulis mendapatkan informasi tentang perkembangan dunia persekolahan. Hasil pelaksanaan kegiatan ini menunjukkan kepada kita bahwa praktik fase kedua dalam model pengajaran langsung perlu dipersiapkan dengan baik (by design), bukan kebetulan (by chance). Hal itu karena fase kedua ini adalah fase inti dari penyajian materi kepada siswa dalam model pengajaran langsung. Dalam praktik ini, guru menampilkan langkah-langkah tertentu dalam menentukan volume kubus dan balok. Langkah-langkah tersebut dimulai dari penentuan panjang sisi-sisi kubus dan balok, serta penggunaannya dalam rumus volume kedua bangun tersebut, hingga langkah terakhir berupa verifikasi hasil kalkulasi volume kubus dan balok untuk memastikan bahwa volume kubus dan balok yang dihitung sudah benar dan memiliki satuan yang sesuai dengan satuan panjang sisi yang digunakan pada kubus dan balok. Pihak sekolah, baik guru dan kepada sekolah, maupun siswa yang dilibatkan dalam proses pembelajaran merespon dengan baik kegiatan ini. Bahkan, ada pengakuan dari siswa bahwa penyajian secara sistematis langkah demi langkah seperti yang ditunjukkan dalam kegiatan ini memberikan banyak manfaat, di antaranya: pemahaman mereka meningkat, mereka termotivasi untuk tahu lebih banyak tentang kubus dan balok, mereka yang bergaya belajar viual dan kinestetik mengaku terbantu belajar lebih baik, skill praktis mereka juga menjadi terbangun, serta mereka yang mengalami kesulitan dalam menentukan volume kubus dan balok menjadi teratasi. Guru-guru pun sejalan dengan respons siswa tersebut.
