Authors: Xing Baixi , Shi Yuehan , Wang Kaiqi , Song Xinjie , Pan Yanhong
Published: February 2024

Third-person pain is an interesting empathy phenomenon that human has the ability to infer characters of other sufferers’ pain by observing their behavior. In the literature, existing studies suggesting that first-person and third-person pain share common features of neuroimage, which indicates that pain behavior will cause influence on both sufferer and the observer. Consequently, it is significant to explore the third-person effects upon the observer. In this study, the evaluation and recognition of third-person pain experience was studied based on user physiological signal analysis. We built a third-person pain multimodal physiological features dataset and applied machine learning methods to explore a third-person pain experience recognition model. A classification accuracy of 95.83% was obtained in third-person pain degree recognition, which demonstrates the effectiveness of our approach. The proposed study shed light on the guiding future exploration of determinants of third-person pain process and empathy intelligence.
Power System Uncertainty Modeling Based on Gaussian Process
Authors: Zhang Tianze
Published: February 2024

In order to solve the problem of low accuracy of parameter estimation in expectation maximization algorithm, a modeling method based on Gaussian component number reduction is proposed. Taking the nonparametric kernel density estimation results as the base Gaussian mixture model, the Gaussian mixture model with any number of Gaussian components can be established by reducing the number of Gaussian components by using the density-preserving hierarchical expectation maximization algorithm, which overcomes the problem that the expectation maximization algorithm has low parameter estimation accuracy when there are many Gaussian components. In order to reduce the burden of modeling calculation under large samples, a hierarchical modeling method based on time scale is proposed. In order to solve the problem of Gaussian component number combination explosion of independent random variables, a hierarchical modeling method of “combination-reduction” is proposed. The proposed method is tested by using measured multidimensional wind speed data and load data with complex distribution characteristics. The experimental results show that the Pearson and Spearman correlation coefficients of GMM constructed based on this method are very close to the sample data. The absolute value of Pearson correlation coefficient error is 0.03739, and the root mean square value of error is 0.02388. The absolute value of Spearman correlation coefficient error is 0.11693, and the root mean square error is 0.05797. Conclusion: The accuracy of the proposed method is significantly better than that of Gaussian mixture model and Copula function method based on expectation maximization algorithm.

Designing Cultural and Creative Products of Chinese Jingchu Patterns Based on Non-Finetuned Text-to-Image Systems
Authors: Wang Yijin
Published: February 2024

Thanks to the massive data training and large base models, content generation based on artificial intelligence technology is booming. Text-to-image (T2I) systems have powerful semantic understanding and aesthetic perception capabilities, creating significant impacts on improving design efficiency and transforming design ecology. Although large-scale AI models already possess efficient multidimensional combination creation abilities, meeting most daily conceptual design requirements, there are still shortcomings when dealing with professional niche concepts, especially non-Western cultural elements. This paper takes Chinese Jingchu patterns as an example and points out the limitations of existing English-based T2I systems in describing sparse concepts and expressing non-Western cultures. Although re-adding large amounts of data and finetuning may solve some problems, the training skills and computing power required are generally not feasible for most designers. Therefore, this study aims to explore the application strategies of non-finetuned T2I systems in the design of Chinese Jingchu pattern cultural and creative products. We designed three methods: image caption-assisted text-to-image, multi-modal prompt, and text-to-image and image blending, and analyzed their characteristics in terms of Texture Fidelity, Product Accuracy, Image Aesthetics, Product Diversity, and Texture Diversity through user evaluation. Finally, we summarize the applicable scenarios and usage suggestions of the three methods.

Does the Manufacturing Industry Also Need Gamification? – A Gamification Design Practice for CNC Machine Tool Skill Training
Authors: Li Tian-shu , Liu Min-yang
Published: February 2024

In CNC (Computer Numerical Control) vocational colleges, the current traditional pedagogy has become conflicting with the learning preferences of the “Generation Z”, resulting in their low sense of competence, low learning autonomy, and insufficient recognition of industry identification. Thus, gamification design provides novel ideas for addressing these issues. Based on the theories of self-determination theory and motivational affordances, this study analyzes the sore points and study needs of students who are majoring in CNC technology at vocational colleges. Hence, according to the 12 dimensions of motivational affordances, the “needs-affordances-features” framework and the course content of CNC technology, a set of gamification design strategies for CNC machine tool skill training is proposed. Consequently, a smartphone-based interactive design practice is completed. Following this design practice, a user experience test is executed, and a positive result is obtained. Theoretically, this study explores the feasibility of modified gamification design processes that combine the motivational affordance model and the “needs-affordances-features” framework. Practically, the integration of gamification design into CNC machine tool skill training is not only a bold attempt to boost the learning motivation of students, but also a practical research foundation for the innovative development and transformation of CNC technology vocational education.

Published: February 2024

Collagen is a fibrillar protein that conforms the conjunctive and connective tissues in the human body, essentially skin, joints, and bones. It is one of the most abundant molecule in many of the living organisms due to its connective role in biological structure. It is a highly versatile material, extensively used in the medical, dental, and pharmacological fields. Collagen is capable of being prepared into cross-linked compacted solids or into lattice-like gels. The collagen family consists of at least 30 different genes, which produce 19 known types of collagen. All collagens contain greater or lesser stretches of triple helix. Some of the superior properties of collagen-based biomaterials, such as biocompatibility, biodegradability, mechanical properties, and cell activities, are pinpointed. These properties make collagen applicable in biomedicine, such as wound healing, tissue engineering, surface coating of medical devices, and skin supplementation.

The purpose of this article is to review the available literature on collagen with special emphasis on its role in development and maintenance of oral tissues. Also it reviews the types of collagen, it’s structure, sources, role in maintaining periodontal tissues and uses in dentistry.
Demand side management using ant colony optimization algorithm in renewable energy integrated smart grid
Authors: Yadav Ravindra Kumar , Bhadoria Vikas Singh , Hrisheekesha P.N.
Published: February 2024

The increasing demand for electrical energy is a result of advancing technologies and changing lifestyles worldwide. Meeting this escalating energy need poses a substantial challenge, especially the difficulty in constructing new conventional power plants due to limited fossil fuel resources. To address this, demand-side management (DSM) in smart grid (SG), integrated with solar photovoltaic energy (SPE) have emerged as a crucial tool for effectively managing electricity demand, ensuring flexibility and reliability. DSM achieves optimal electricity utilization by rescheduling the operation schedules of consumer appliances and carefully adjusting their demand profiles. Integrating DSM into a smart grid framework is highly advantageous for the power industry’s pursuit of sustainable energy goals. While various heuristic-based optimization techniques have been employed for DSM, the focus on SPE has been limited to small-scale residential loads. This study utilizes the Ant Colony Optimization (ACO) algorithm to tackle a day ahead DSM minimization problem, considering SPE in areas with large number of appliances. The DSM minimization problem falls into the category of discrete combinatorial problems, making it well-suited for ACO optimization. The self-healing, self-protection, and self-organizing attributes of ACO make it particularly effective for DSM solutions. Residential, commercial, and industrial loads, with and without SPE integration, are considered to demonstrate the efficacy of the proposed ACO algorithm. Simulation results are compared with other studies in the literature, including Evolutionary Algorithm (EA), Moth Flame Optimization (MFO), and Bacterial Foraging Optimization (BFO), in terms of reducing consumer’s cost of energy (CCE) and utility peak load (UPL). The findings indicate that the proposed ACO algorithm outperforms the other algorithms considered in the current context.

Fuzzy AHP and fuzzy TOPSIS methods of analysing online impulsive buying of organic food: A cognitive-affective decision-making perspective
Authors: Aljanabi Abdulqadir Rahomee Ahmed , Ghafour Karzan Mahdi
Published: February 2024

Buying decisions are influenced by a variety of factors that can give rise to impulsive, unplanned, or even irrational purchases. Research has examined the motivational factors that foster organic food consumption, but no study has explored the relative weights of these factors and whether their effects vary depending on the type of food. This study adopted the cognitive-affective perspective to examine the antecedents of online impulsive buying of organic food using a sample of 452 consumers living in Baghdad, Iraq. The fuzzy AHP and fuzzy TOPSIS methods were used to rank five organic food alternatives. The results revealed that the effects of cognitive factors on organic food purchases differ from those of affective factors.
Distinguishing Photon Interactions: Source Well vs. External Fields
Authors: Thakur Soumendra Nath
Published: February 2024

This study delves into the nuanced interactions of photons or waves with gravitational fields, focusing on the distinction between their encounters with the gravitational wells of source objects and external massive bodies. When photons or waves escape a source gravitational well, such as that of a star or black hole, they expend energy, leading to a gravitational redshift characterized by an increase in wavelength. Conversely, when traversing through the gravitational field of external massive bodies like planets or galaxies, photons or waves maintain their inherent energy. However, their paths may bend a result of momentum exchange with the gravitational field. By discerning between these interactions, we gain deeper insights into how gravitational effects manifest in the behaviour of photons or waves, offering valuable contributions to the fields of astrophysics and gravitational physics. The mathematical formulations presented in this study provide a quantitative framework for understanding these interactions, further enhancing our comprehension of the intricate relationship between gravity and light propagation in the universe.
ALR_Sim_tracks — Trajectory Simulator Software to Assist the Search for Favourable Trajectories for the Exploration of the Triple Asteroid 2001-SN263 From the Laser Altimeter Point of View
Authors: Vicente de Brum Antonio Gil
Published: February 2024

This paper presents a simulator tool, named _ALR_Sim_tracks_, dedicated to the preliminary analysis of trajectories planned for a space mission to explore the surface of celestial bodies using optical sensors, such as a laser altimeter. The software offers a prediction of the coverage results obtainable in a simulated exploration campaign carried out along a selected/simulated trajectory, for the set of target and instrument parameters used (in qualitative and quantitative terms, including 2D/3D visualizations). The software was created to perform an analysis that would allow the identification of favourable trajectories for conducting the intended exploration of the triple asteroid 2001-SN263 during Brazil's first deep space mission (ASTER mission) from the point of view of the Laser Altimeter being designed to fly in this mission, which was named ALR. Because there are few tools described and available for this type of analysis in the literature, and these are generally complex, proprietary and of restricted use, this work aims to help broaden the understanding of the process involved and the access to this type of tool. The paper contains the description of the _ALR_Sim_tracks_ software and everything involved in its operation. The illustrative examples presented in this text involve the exploration of an asteroid from the point of view of a laser altimeter, because this was the initial motivation for creating the simulator. However, other optical instruments with similar operation, used to explore other types of targets (e.g. planets or moons), are also considered when suitable modelling is available.
Notes on the Implications of Ignoring Bayes’ Rule in Search and Rescue Practice in the UK
Authors: Clark Andre
Published: February 2024

Thomas Bayes (1702-1761) has had a big influence on the science of inference since he discovered the mathematically correct way of adjusting probabilities to account for new evidence. Nonetheless, it is still the case that in practice it is not always clear where and when to apply the rule he derived, or the consequences of not doing so. In this note, the effects of not doing so when searching an area of ground for a missing person (misper), where the chances of finding them depends both on whether they are there and how well the ground is searched, is investigated. This investigation suggests that within the range of probabilities that generally apply to search operations in rural settings in the UK, the widespread failure to apply Bayes’ rule may incline search managers to widen search areas more than is warranted by the evidence and may thereby reduce overall search effectiveness (ceteris paribus).

La piel es la capa externa del cuerpo humano que cumple funciones de barrera contra diversos agentes ambientales, la radiación ultravioleta (UV) emitida por el sol es absorbida en la epidermis provocando daños como manchas, irritaciones, melanomas y arrugas, por lo que su protección a base de compuestos fotoprotectores y tratamientos aclaradores son necesarios. Los productos cosméticos convencionales se basan en una composición y síntesis química donde algunos de estos compuestos pueden resultar dañinos para la piel y su microbiota. Una solución y propuesta a estos elementos es la utilización de productos naturales, enfocándose en los microorganismos presentes en la piel que cuentan con propiedades probióticas y producen metabolitos fotoprotectores y aclaradores. El presente manuscrito discute el mecanismo de fotoprotección y aclaramiento, asociados con distintos microorganismos y su potencial de producción a una escala industrial.

Perbandingan Pemanfaatan Hak Cipta Sebagai Objek Jaminan Fidusia di Negara Indonesia & Amerika Serikat
Authors: Fathurrahman Ali Masykur , Sopiyana Muhammad
Published: February 2024

Kajian ini akan memaparkan secara komprehensif berbagai kendala penerapan hak cipta sebagai objek jaminan fidusia di Indonesia. Penulis membuat perbandingan hukum hak cipta di Indonesia dan Amerika Serikat sehingga dari perbandingan tersebut dapat dirumuskan berbagai solusi untuk mengatasi kendala penerapan hak cipta sebagai benda jaminan di Indonesia. Penelitian ini merupakan penelitian yuridis normatif yang dilakukan dengan menggunakan data sekunder berupa bahan hukum primer, sekunder dan tersier kemudian dianalisis secara kualitatif untuk menghasilkan luaran deskriptif analitis. Hasil penelitian ini menunjukkan bahwa terdapat beberapa permasalahan yang menghambat penggunaan hak cipta sebagai objek jaminan fidusia di Indonesia yaitu: 1) penggunaan hak cipta sebagai objek jaminan fidusia belum diatur secara komprehensif melalui hukum Indonesia; 2) belum ada peraturan yang mengatur secara jelas kualifikasi mengenai kriteria hak cipta yang dapat dijadikan sebagai objek jaminan fidusia 3) belum ada lembaga dan mekanisme untuk menilai nilai ekonomi hak cipta; 4) belum tersedia mekanisme pengalihan kepemilikan dan pelaksanaan hak cipta sebagai objek agunan; 5) hak cipta sebagai bagian dari hak kekayaan intelektual masih belum diakui sebagai aset oleh Otoritas Jasa Keuangan dan Bank Indonesia. Ada banyak alternatif untuk mengatasi masalah tersebut, salah satunya dengan mengadopsi beberapa mekanisme yang telah diterapkan dalam regulasi hak cipta di Amerika Serikat, yaitu: 1) mengoptimalkan peran Direktorat Jenderal Hak Kekayaan Intelektual Kementerian Hukum dan Hak Asasi Manusia. ; 2) menerapkan modul 11 WIPO sebagai standar kualifikasi hak cipta; 3) menerapkan modul 11 WIPO sebagai standar penilaian nilai ekonomi hak cipta; 4) menerbitkan peraturan tentang pencatatan dan pelaksanaan hak cipta; 5) memperluas cakupan aset yang diakui oleh Otoritas Jasa Keuangan dan Bank Indonesia.
