Signal Filtering Using Neuromorphic Measurements
Authors: Florescu Dorian , Coca Daniel
Published: December 2023

Digital filtering is a fundamental technique in digital signal processing, which operates on a digital sequence without any information on how the sequence was generated. This paper proposes a methodology for designing the equivalent of digital filtering for neuromorphic samples, which are a low-power alternative to conventional digital samples. In the literature, filtering using neuromorphic samples is performed by filtering the reconstructed analog signal, which is required to belong to a predefined input space. We show that this requirement is not necessary, and introduce a new method for computing the neuromorphic samples of the filter output directly from the input samples, backed by theoretical guarantees. We show numerically that we can achieve a similar accuracy compared to that of the conventional method. However, given that we bypass the analog signal reconstruction step, our results show significantly reduced computation time for the proposed method and good performance even when signal recovery is not possible.

Published: December 2023

To explore the influence of human activities on natural resources and the correlation between these two characteristics, taking the region around Poyang Lake in China as the research area. Utilizing data from 2010, 2013, 2015, 2017, and 2020, including remote sensing, gross domestic product (GDP), and population density data, the human activity intensity (HAI) and resource carrying capacity (RCC) were calculated using relevant models. Analyzing the dynamic change characteristics, the temporal and spatial correlations, and the interaction between the two aspects, bivariate spatial autocorrelation and other methods were used. The results show that: (1) from 2010 to 2020, there was a significant increasing trend in the HAI, while the RCC remained at a generally stable level. (2) In both the temporal and spatial dimensions, there was a certain positive correlation between the HAI and RCC. Their interaction, however, is primarily based on the intrinsic resources and human activity factors within each region, with limited observable factor flow between regions. (3) Regions with the medium level of HAI have greater development potential. The results are expected to enrich the research on human activities and natural resources in the region around Poyang Lake in China and provide a reference for relevant planning.
Using a Node–Child Matrix to Address the Quickest Path Problem in Multistate Flow Networks under Transmission Cost Constraints
Authors: Forghani-elahabad Majid , Alsalami Omar Mutab
Published: December 2023

The quickest path problem in multistate flow networks, which is also known as the quickest path reliability problem (QPRP), aims at calculating the probability of successfully sending a minimum of d flow units/data/commodity from a source node to a destination node via one minimal path (MP) within a specified time frame of T units. Several exact and approximative algorithms have been proposed in the literature to address this problem. Most of the exact algorithms in the literature need prior knowledge of all of the network’s minimal paths (MPs), which is considered a weak point. In addition to the time, the budget is always limited in real-world systems, making it an essential consideration in the analysis of systems’ performance. Hence, this study considers the QPRP under cost constraints and provides an efficient approach based on a node–child matrix to address the problem without knowing the MPs. We show the correctness of the algorithm, compute the complexity results, illustrate it through a benchmark example, and describe our extensive experimental results on one thousand randomly generated test problems and well-established benchmarks to showcase its practical superiority over the available algorithms in the literature.

Published: December 2023

Here, we present a simple and green method of preparing Au-Ag bimetallic nanoparticles (NPs) with a tunable surface plasmon resonance (SPR) wavelength by using picosecond laser irradiation. Au-Ag alloy NPs have been produced by irradiating the solutions containing respective metallic salts in a polyvinyl alcohol (PVA) matrix using a picosecond laser in a single-step process. The SPR wavelength of the Au-Ag bimetallic NPs is observed to be shifted/changed with the Au-Ag concentration and the laser irradiation parameters. The Au-Ag NPs embedded in the PVA matrix are advantageous for Surface-Enhanced Raman scattering (SERS) applications. The estimated enhancement factors (EFs) were observed to vary as a function of conditions of the Au-Ag bimetallic alloy NPs synthesis and also on the concentration of Au at a fixed input fluence of irradiation. The SERS active platforms of Au-Ag bimetallic NPs showed EFs as high as of the order of 108 for Crystal Violet (CV) dye samples at nano molar concentrations. The present study demonstrates a simple, single-step, and green method that fabricates Au-Ag alloy-based nanocomposites suitable for SERS investigations with significantly higher orders of EFs.
Study of the Grinding Process by Friction of Cereal Grains in Stone Mills
Authors: Ilie Filip , Cotici Constantin Daniel , Hristache Andrei-Florin
Published: December 2023

The grinding process via friction at the micro-scale in a mill with stones is considered a variable combination of contacts, with two-body (the asperities of lower millstone in direct contact with the asperities of upper millstone) and three-body (micro-particles of ground seeds trapped between the asperities of lower and upper stones of the mill) contacts. Three elements are described: (1) the mechanical contact of the asperities of the lower and upper millstones to predict pressures on asperities by modeling; (2) tests on a millstone sample covered with grinding particles; and (3) tests on a wafer sample formed by the millstones with the grinding particles between them. This paper highlights the combined effects of the micro-scale friction via individual measurements, using an analytical model to sum these effects and validating the model by performing several experiments. An efficiency grind by friction assumes the grain’s movement and interaction between the seeds and solid surfaces, and is highlighted through theoretical and experimental studies. Topography analysis of the surface of the millstones reveals the model of microscopic frictional force. Endpoint measurements (the traces of the surface topography evolution) enable model verification in the grinding process. Thus, the results obtained in the grinding process in the stone mills via friction have practical utility through research benefits. Therefore, they allow for the improvement of quality, reliability, flexible grinding, quality control of the flours, and uniformity degree (fineness/shredding).

Published: December 2023

Lignocellulose is a complex and abundant biomass source, and finding ways to efficiently break it down is essential for various applications, including bioenergy production and waste management. Biogas production can be significantly enhanced by adding rumen fluid to the anaerobic digestion process, which contains a variety of microorganisms with the enzyme activity necessary to breakdown complex lignocellulosic materials. This study examined the influence of rumen anaerobic bacteria inoculum on alfalfa biomass biogas yield and quality. Inoculation experiments were performed, and the higher biogas yield from organic matter was gained in experiment (A), with a rumen fluid addition of 340 ± 3.2 L/kgVS, compared to the utilization of a digestate alone in (B), 238 ± 1.2 L/kgVS. The results demonstrated that a pretreatment temperature of 37 °C (experiment D) yielded the highest biogas production, 381 ± 3.9 L/kgVS, and maintained a high methane content of 63.9 ± 1.9%. Notably, pretreatment at 25 °C resulted in only a 3% increase over the raw sample and a pretreatment at 50 °C (respectively, experiments C and E) showed no significant changes, emphasizing the sensitivity of pretreatment efficiency to temperature variations.
Managing Religious Diversity in the Private Sphere in Post-Secular Societies: Lessons from Business and Human Rights
Authors: Letnar Černič Jernej
Published: December 2023

This article discusses managing religious diversity in post-secular societies by drawing lessons from business and human rights. Managing religious diversity has been traditionally played out in the realms of the state. A state’s primary obligation is to respect and protect religious diversity in its society. This article looks beyond the state by arguing that managing diversity is a two-way street. It submits that business and human rights standards are benchmarks by which state and corporations’ effective management of religious diversity should be measured and supervised. This article argues that business and human rights standards, such as the United Nations Guiding Principles on Business and Human Rights, establish the obligations of business and other private actors, such as religious communities, to respect and protect human rights in private relations. Businesses carry negative and positive obligations to employ a human-rights-based approach to managing religious diversity in their business operations. Religious communities, for their part, have to manage religious diversity to the extent their autonomy and self-governance allow for it. Equipped with this knowledge, this article concludes that business and human standards, including the United Nations Guiding Principles, represent the standards that business and religious communities should comply with in managing religious diversity in private relationships.
Enhancing Sustainable Finance through Green Hydrogen Equity Investments: A Multifaceted Risk-Return Analysis
Authors: Tudor Cristiana
Published: December 2023

Amidst the global push for decarbonization, green hydrogen has gained recognition as a versatile and clean energy carrier, prompting the financial sector to introduce specialized investment instruments like Green Hydrogen Exchange-Traded Funds (ETFs). Despite the nascent nature of research on green hydrogen portfolio performance, this study examines two key green hydrogen ETFs (i.e., HJEN and HDRO) from April 2021–May 2023, aiming at conducting a multifaceted exploration of their performance, isolating and measuring their sensitivity to the primary market factor, and assessing the capabilities of systematic trading strategies to preserve capital and minimize losses during market downturns. The results spotlight lower returns and higher risks in green hydrogen investments compared to conventional equity (proxied by ETFs offering exposure to developed markets—EFA and emerging markets—EEM) and green energy portfolios (proxied by the ETF ICLN). To comprehensively evaluate performance, an array of risk-adjusted metrics, including Std Sharpe, ES Sharpe, VaR Sharpe, Information ratio, Sortino ratio, Treynor ratio, and various downside risk metrics (historical VaR, modified VaR, Expected Shortfall, loss deviation, downside deviation, and maximum drawdown) are employed, offering a nuanced understanding of the investment landscape. Moreover, single-factor models highlight significant systematic market risk, reflected in notably high beta coefficients, negative alphas, and active premia, underscoring the sensitivity of green hydrogen investments to market fluctuations. Despite these challenges, a silver lining emerges as the study demonstrates the efficacy of implementing straightforward Dual Moving Average Crossover (DMAC) trading strategies. These strategies significantly enhance the risk-return profile of green hydrogen portfolios, offering investors a pathway to align financial and social objectives within their equity portfolios. This research is motivated by the need to provide market players, policymakers, and stakeholders with valuable insights into the benefits and risks associated with green hydrogen investment, considering its potential to reshape the global energy landscape.

Published: December 2023

Study purpose: This study aims to investigate the impact of CDSS on patient safety through the experiences of nursing staff. Methods: As the study intends to arrive at specific conclusions on the perceptions of nurses on the impact of CDSS on patients’ safety, a cross-sectional quantitative survey design is adopted in this study. The Hospital Survey of Patients’ Safety Culture (HSOPSC) was used in this study to assess the influence of CDSS on various factors of patient safety. A total of 473 nurses from eight hospitals in Saudi Arabia participated in this study. Results: The PRR of ‘team work within units’ was identified to be the highest (65.9%), followed by ‘hands-off and transitions’ (64.7%), ‘overall patents safety’ (64.1%), and ‘frequency of reports’ that were corrected (61.1%). Communication openness (27.9%) achieved the lowest PRR; while team work across units (2.82) achieved the lowest mean score. Conclusion: The CDSS needs to be integrated with other interventions that promote communication and develop a supportive and cooperative culture among the nurses for ensuring a positive patient safety culture in Saudi Arabian hospitals.
The Influence of General and Local Muscle Fatigue on Kinematics and Plantar Pressure Distribution during Running: A Systematic Review and Meta-Analysis
Authors: Hazzaa Walaaeldin Aly , Hottenrott Laura , Kamal Manar Ahmed , Mattes Klaus
Published: December 2023

Fatigue has the potential to alter how impact forces are absorbed during running, heightening the risk of injury. Conflicting findings exist regarding alterations in both kinematics and plantar pressure. Thus, this systematic review and subsequent meta-analysis were conducted to investigate the impact of general and localized muscle fatigue on kinematics and plantar pressure distribution during running. Initial searches were executed on 30 November 2021 and updated on 29 April 2023, encompassing PubMed, The Cochrane Library, SPORTDiscus, and Web of Science without imposing any restrictions on publication dates or employing additional filters. Our PECOS criteria included cross-sectional studies on healthy adults during their treadmill running to mainly evaluate local muscle fatigue, plantar pressure distribution, biomechanics of running (kinematics, kinetics, and EMG results), and temporospatial parameters. The literature search identified 6626 records, with 4626 studies removed for titles and abstract screening. Two hundred and one articles were selected for full-text screening, and 20 studies were included in qualitative data synthesis. The pooled analysis showed a non-significant decrease in maximum pressure under the right forefoot’s metatarsus, which was more than the left rearfoot after local muscle fatigue at a velocity of 15 km/h (p-values = 0.48 and 0.62). The results were homogeneous and showed that local muscle fatigue did not significantly affect the right forefoot’s stride frequency and length (p-values = 0.75 and 0.38). Strength training for the foot muscles, mainly focusing on the dorsiflexors, is recommended to prevent running-related injuries. Utilizing a standardized knee and ankle joint muscle fatigue assessment protocol is advised. Future experiments should focus on various shoes for running and varying foot strike patterns for injury prevention.

Background: Suppression of HBV DNA, inhibition of HBV surface (HBsAg) production and therapeutic vaccination to reverse HBV-specific T-cell exhaustion in chronic HBV patients are likely required to achieve a functional cure. In the AAV-HBV mouse model, therapeutic vaccination can be effective in clearing HBV when HBsAg levels are low. Using a single-cell approach, we investigated the liver immune environment with different levels of HBsAg and sustained HBsAg loss through treatment with a GalNAc-HBV-siRNA followed by therapeutic vaccination. Methods: AAV-HBV-transduced C57BL/6 mice were treated with GalNAc-HBV-siRNA to lower HBsAg levels and then vaccinated using a DNA vaccine. We used single-cell RNA and V(D)J sequencing to understand liver immune microenvironment changes. Results: GalNAc-HBV-siRNA, followed by therapeutic vaccination, achieved sustained HBsAg loss in all mice. This was accompanied by CD4 follicular helper T-cell induction, polyclonal activation of CD8 T cells and clonal expansion of plasma cells that were responsible for antibody production. Conclusions: This study provides novel insights into liver immune changes at the single-cell level, highlighting the correlation between induced reduction of HBsAg levels and clonal expansion of CD4, CD8 T cells and plasma cells in the liver upon HBV siRNA and subsequent therapeutic vaccination.

La gestion stratégique d'une technologie singulière : les voilures tournantes en France de l'autogyre au Tigre
Authors: Seiffert Marc-Daniel
Published: December 2023

To explain the dominant position of the firm Eurocopter in the global helicopter market since the 1990s it is necessary to :

- employ theoretical concepts from several disciplines : industrial economics, strategic management, business history and the history of technology

- adopt a lengthy perspective (a century in time)

It was by long and complex learning processes within the framework of a national system of innovation specific to France that the French helicopter industry was able to become competitive. What is plainly demonstrable is, on the one hand, the very strong affiliations between the successive generations of French rotary-winged aircraft and, on the other, some major technological breaks with the past.

It is clear that only the French state taking a crucially important role gave momentum and continuity to this high-technology industry. Radical uncertainties -about the correctness of technical choices and about new business opportunities — that typify the experience of innovative industries therefore necessitated stability, and this came from political choices made for the long-term.
Les juridictions d'exception du régime de Vichy ou la démilitarisation de l'exception
Authors: Giraudier Vincent
Published: December 2023

Exceptional jurisdictions under the Vichy regime or the demilitarisation of the exception

Exceptional legal jurisdictions under Vichy testify to the regime's dictatorial nature and its progressive slide towards a «Milice state». But they also reveal a clear tendency to remove from the military sphere those legal procedures that belonged to the more traditional competent judicial authorities.

If the courts-martial known as the Gannat system and the Special Criminal Court, set up in 1940, were essentially military in nature, they were replaced from the summer of 1941 by special sections, conjointly civil and military in origin, and by two new civilian jurisdictions tasked with acting against the «deviancies» of «anti-France». These were Vichy's Special Tribunals and the Tribunal d'Etat. These juridical authorities, where professional magistrates sat side-by-side with the political partisans of the Vichy regime (including some military figures) themselves saw their repressive role decrease from the beginning of 1 944 when they found themselves «flanked» by Vichy Milice «tribunals».
Les exploits de Gabriel Aubaret et la délimitation des frontières de la Serbie au lendemain du traité de 1878
Authors: Bussiere Laurent
Published: December 2023

This article examines the activities of the international commission charged with drawing the new frontiers of Serbia after the Treaty of Berlin in 1878 had enlarged Serbian lands by allotting them the territory to Serbia's south-east, adjoining Kosovo. France, through her juridical involvement in the Eastern Question, was able to breach the diplomatic isolation in which she had been placed by the German Chancellor, Bismarck The international position of France, together with the naval training of the French consul, Gabriel Aubaret, that made him open to foreign realities, permitted his nomination as the commission's president. Tne lands apportioned to Serbia were inhabited by a hererogenous mix of different ethnicities. The commission had to deal with thje Albanian population's hostility, the difficulties of the task of frontier delineation itself, and the problem of achieving consensus. Its work reflected the intensity of Balkan rivalries in the era preceding the First World War.

Coal Boiler Plant at PT. Salim Ivomas Pratama is a plant for making steam, almost all activities in the cooking oil and margarine production process utilize electrical energy, such as submersible and centrifugal electric motors with controllers, computers, AC inverters, and many others which include non-linear loads. Electrical load whose correlation between voltage and current is unbalanced, this non-linear load will result in harmonic disturbances in the electric power system which causes a reduction in the service life of electrical equipment. Harmonics are defined as voltage and current frequency distortions that are not sinusoidal from pure frequencies. This study aims to determine how effective the active filter design simulated with the PSIM Software is in reducing harmonics with a non-linear load of 3 VSD connected to a 55 kW, 0.37 kW, and 7.5 kW induction motor. The results of measurements and analysis show that there are harmonics on the panel. SDP with a current harmonic value for phase R of 26.6%, phase S of 27.5%, and phase T of 25.5%, when compared with standard harmonics, all phases exceed the standard SPLN with a standard value of 20%. Then it is necessary to reduce harmonics with an active filter, after designing andsimulating it in the PSIM software the simulation results show that the current harmonics have changed for phase R by 3.3%, phase S by 4.0%, and phase T by 3,4 %. This shows that the design of the active filter is quite effective in mitigation a harmonic, to then be applied in practice at PT. Salim Ivomas Pratama in reduction the harmonics in a coal boiler plant.

Motor induksi merupakan jenis motor yang paling umum di gunakan di industri maupun di rumah tangga dengan beberapa keunggulan diantaranya kontruksi yang sederhana dan mudahnya perawatan. Namun, motor induksi juga memiliki kelemahan, salah satunya adalah penggunaan arus start yang besar dalam waktu singkat yang dapat menyebabkan drop tegangan pada jaringan listrik. Penelitian ini berfokus pada perancangan dan pembuatan softstarter guna menekan lonjakan arus start. Metode yang digunakan adalah pengendalian sudut penyalaan triac menggunakan rangkaian trigger yang dikendalikan oleh  arduino dengan optocouper sebagai detektor fasanya. Dengan mengatur sudut penyalaan triac tersebut maka tegangan selama proses starting motor dapat diatur. Selain itu softstarter ini dapat mengatur lamanya waktu starting motor dari mulai tegangan 0 volt hingga tegangan nominal. Pengujian alat dilakukan terhadap motor induksi 3 phasa dengan spesifikasi daya 1HP dan arus nominal 2 A dengan waktu start bervariasi antara 3 detik, 7 detik dan 10 detik. Dari hasil pengujian didapat kenaikan tegangan input motor yang linear terhadap waktu yang diseting. Saat proses kenaikan tegangan, pada fasa T terdapat sedikit perbedaan nilai terhadap 2 phasa lainnya, namun di akhir proses starting tegangan ketiga phasanya kembali mendekati nilai yang sama. Sedangkan untuk arus start-nya cenderung mengikuti kenaikan tegangan yang linier namun fluktuatif dengan nilai arus starting lebih rendah dari pada metode start DOL.

There are three objectives in this research. The first objective is to analyze Indonesia's commitment to reducing greenhouse gas (GHG) emissions. The second objective is to examine the carbon tax regulations that have been set by the government. The third objective is to analyze the potential of a carbon tax in environmental conservation. The research method used is the descriptive qualitative method. This study elaborates on three research findings. The first research result shows that the Indonesian government has committed to reducing GHG emissions. This is stated in sustainable and environmentally friendly development activities and is on the 2020-2024 National Medium-Term Development Plan agenda. The government also stipulates laws and regulations to reduce gas emissions. The second research result elaborates that the government has passed the carbon tax regulation as an effort to accelerate climate change mitigation. Carbon tax provisions are applied to the use of carbon-containing products or activities that produce carbon emissions. The third research result explains that the determination of a carbon tax has the potential to protect the environment. Thus, the carbon tax is used to correct the social costs arising from negative externalities due to environmental pollution.
