On the Effect of Current Stabilizer on Dynamics of a Small Hybrid Wind Power Generator
Authors: Budanov V. M. , Holub A. P. , Dosaev M. Z. , Selyutskiy Y. D.
Published: November 2024

The use of small wind power generators remains quite relevant. In particular, they can be efficient for charging batteries in remote locations where there is no centralized power supply (including in the Arctic, Far East, etc.). They can also be used as part of missions to planets with atmospheres. One of the promising design solutions for a small wind power generator with a vertical axis of rotation is a hybrid device. It consists of two wind turbines that have a common axis of rotation: external (Darrieus wind turbine) and internal (Savonius rotor). This scheme represents a compromise between the relatively high power coefficient of the Darrieus turbine and the good startup characteristics the Savonius rotor. It is known that one of the typical battery charging modes is constant current charging. Here we consider a hybrid installation, the generator of which is connected to a current stabilizer. The load is simulated with an active resistance. It is assumed that the generator is a DC generator. A closed mathematical model of the studied system is constructed. The aerodynamic load is described using the quasi-steady approach. It is assumed that the characteristic time of electrical processes is much smaller than the characteristic time of mechanical processes. The influence of load resistance on the behavior of the system is investigated. It is shown that, under certain conditions, several steady modes (up to five) exist in the system. In this case, at least two of them are attracting. Therefore, the hysteresis of the angular speed of the steady mode is possible when the load resistance changes. It should be noted that in a number of situations, an unstable steady mode (which corresponds to a lower angular speed of the turbine than a stable one) may be preferable (for example, to reduce the load on bearings). In this regard, a resistance control strategy has been proposed to ensure stabilization of the unstable stationary regime.

Published: November 2024

During its existence, electron microscopy has become one of the reference methods for assessing the structural and functional state of cells, tissues and organs, and an extensive evidence base has been formed that allows its use in the creation and formation of a biobank. The selection of sources for the literature review was carried out using keywords based on publications over the past 20 years. The publications presented in the review were selected by searching the eLIBRARY.RU, PubMed and Scopus databases. Based on foreign and domestic experience in the work of biobanks, we can distinguish four areas that determine the effectiveness of the use of electron microscopy studies as a component of its work. Firstly, it is control of microbiological contamination of a biological sample. The effectiveness of electron microscopy in detecting contamination of a biological sample with bacteria, fungi and viruses is comparable to the effectiveness of classical microbiological techniques. Secondly, it is a diagnostic tool that allows you to identify or confirm the presence in a sample of a pathogenetic process that is of interest for biobanking: tumor growth, atherosclerotic vessel damage, etc. Thirdly, it is quality control for cryopreservation of samples. A wide range of morphological characteristics of the ultramicroscopic structure of cells and microanatomical formations makes it possible to characterize the quality of cryopreservation and quantify the degree of damage, which contributes to the unification and standardization of biobanking. Transmission electron microscopy is the most informative in this matter. Fourthly, this is the basis for digitalization of the results obtained and the formation of an interdisciplinary biobank repository, which allows the use of “big date” technologies for fundamental research. The compliance of the biobank profile with the economic, scientific and industrial characteristics of the infrastructure of the industry or region is of great importance. Electron microscopy data are successfully combined with the results of molecular studies, which allows the formation of interdisciplinary metadata databases suitable for interregional and interdisciplinary scientific integrations. The latter makes it possible to use electron microscopy data to solve a wide range of applied and interdisciplinary problems. The above allows us to consider scanning and transmission microscopy methods as one of the key methods in the development of biobanking in the region.
Point-of-Care Additive Fused Filament Manufacturing of Patient-Specific Triflange Acetabular Reconstruction Implants
Authors:   , Gandhi Ansh Asit , Allen Fred D.
Published: November 2024

Significant loss of bone, resulting in pelvic discontinuity, often requires surgical reconstruction to integrate patient-specific triflange cup implants for severe cases. Current cups are typically composed of metal alloys that are additively manufactured using methods like laser-powder bed fusion (LPBF). This can inflate the cost and difficulty of achieving the precision necessary to manufacture patient-specific geometry, resulting in the use of standardized implants. Additionally, metal implants have been known to cause side effects like metallosis and tissue damage. To address these difficulties, more practical additive manufacturing methods with biocompatible thermoplastics are being considered that can be additively manufactured on-site at the hospital. This study aims to evaluate fused filament fabrication (FFF) for its effectiveness in developing dimensionally accurate patient-specific triflange cup implants. Two triflange cup designs were developed and tested. These designs were individually generated to be custom-fitted to a male and female CT scan sourced and segmented from the New Mexico Decedent Imaging Database (NMDID). After approval by an orthopaedic surgeon, multiple male and female samples were fabricated in polylactic acid (PLA) using FFF. Samples were then scanned three-dimensionally and computationally verified by comparison with the original implant designs. All nine implant samples were verified to be greater than 95% within acceptable tolerances. Verification was confirmed with statistical testing that yielded p-values significantly less than 0.01 indicating that the population mean of percent within tolerance, or dimensional accuracy, is statistically significantly greater than 95%. By evaluating FFF as a triflange cup manufacturing method, this study makes strides in developing a workflow for orthopaedic surgeons to fabricate patient-specific implants on-site, reducing lead time and the likelihood of revisional procedures.
Optimising the Fashion E-Commerce Journey: A Data-Driven Approach to Customer Retention
Authors: Fadhila Hasna Luthfiana , Permadi Vynska Amalia , Tahalea Sylvert Prian
Published: November 2024

A fashion e-commerce company offers a wide range of products from domestic and international brands that are popular with young people. However, there has been an increase in non-organically acquired customers, many of whom do not return to make repeat purchases. This has led to a higher customer churn rate, with a significant proportion of non-organically sourced customers failing to become repeat purchasers. Consequently, a churn analysis and prediction model were developed to address this issue. This paper employs the Recency, Frequency, and Monetary (RFM) framework for churn analysis and prediction. The framework is underpinned by three key dimensions: last purchase recency, purchase frequency, and total transaction value. Seven machine learning algorithms were evaluated to identify the optimal approach. Following a comparative analysis of these models, Random Forest emerged as the superior algorithm, demonstrating an accuracy of 0.99, precision of 0.97, recall of 0.99, ROC AUC of 0.98, and F1-score of 0.97. Consequently, this model will be utilized for churn prediction. Based on the analysis and modelling, several recommendations are offered to enhance customer retention for the fashion e-commerce platform. In addition to predicting churn, this paper provides insights into potential refinements to the churn prediction model, such as real-time monitoring, personalized customer experiences, analysis of customer feedback, and lifetime value analysis.
Strange fates, strange storytelling. Adalbert Stifter’s novella “Turmalin” and Gérard Genette’s concept of ‘zero focalization’
Authors: Müller Dominik
Published: November 2024

Unter den eher kontraintuitiven Begriffen der Erzähltheorie Gérard Genettes, die sich auch im deutschsprachigen Raum durchgesetzt hat, ist derjenige der ‚Nullfokalisierung‘ ein spezielles Ärgernis. Zum Anfang der Erzählung „Turmalin“ aus dem Zyklus „Bunte Steine“ von Adalbert Stifter scheint er aber zu passen und zu helfen, das Ausgefallene und Befremdliche der hier angewandten Erzählweise zu erfassen. Es geht um einen Ehebruch, der eine Familie zerstört. Statt aber darüber zu reden, konzentriert sich die Erzählung auf die Schilderung der Wohnungseinrichtung der Familie. Seitenblicke auf die Vorstufe der Erzählung, die einleitenden Erzählkommentare, auf Franz Grillparzers Novelle „Der arme Spielmann“ als Referenztext und auf die Schilderung verschiedener Kunstpraktiken, denen Figuren der Erzählung nachgehen, erlauben, das Ethos dieser höchst sonderbaren ‚Nullfokalisierung‘ deutlich zu machen: eine versehrte Ästhetik zur Darstellung versehrter Menschen.

Succession planning in higher education: A systematic literature review (2012–2022)
Authors: Hoque Kazi Enamul , Zheng Chunli
Published: November 2024

This research investigates the dynamic landscape of succession planning (SP) strategies in higher education, with a focus on synthesizing existing literature to guide improvements in presidential succession practices. The intense global competition in higher education has led to imbalances in the quantity and composition of potential successors, hindering institutions’ rapid advancement and affecting their competitiveness on the global stage. The study addresses critical challenges such as attracting, retaining, and nurturing successors in key positions beyond material incentives. Employing a literature analysis methodology, the research comprehensively examines the existing body of literature related to succession planning, offering recommendations to promote stability in leadership, foster continuous talent development, and mitigate talent crises. The study evaluates the current state of succession planning in higher education, identifying issues and their root causes. It provides a summary and analysis of ongoing research efforts related to successor quality, team formation, and cultivation models. Despite advancements through national talent cultivation policies, persistent challenges like talent scarcity, the absence of gender-inclusive succession plans, a lack of originality, and inconsistent staff flow hinder progress. The research attributes these challenges to traditional personnel systems and university administrators. Proactive measures are proposed, including creating awareness of succession planning, advocating for personnel mechanism reform, establishing a comprehensive training system, and developing a scientifically-grounded succession plan. Though the study aims to contribute to leadership development and address pressing issues faced by higher education institutions, with only a limited number utilizing mixed techniques, it restricted the comprehensive inclusion of social context knowledge and evidence regarding the motivations, beliefs, and experiences of individuals in this investigation.

This paper presents the theoretical foundations for an approach to automated solutions of positional problems involving intersections of geometric objects in Euclidean space. A conceptual framework is developed based on concepts and definitions related to the equivalence relation known in set theory. This framework includes: an equivalence relation defined on the set of geometric objects in Euclidean space; the dimension and factorization of the object set, represented as a collection of equivalence classes; and the projected factor set of space. A set-theoretic basis for representing the projection operation is provided, enabling the development of constructive algorithms to solve positional problems involving intersections of spatial geometric objects. These algorithms have been implemented within the KOMPAS-3D CAD environment. The theoretical foundations and analysis of the algorithm functionality establish definitions for "geometric modeling" and "3D modeling." The proposed approach to automating positional problem solutions essentially constitutes a 3D model of these solutions through the creation of a virtual model. The paper includes examples of automated 3D solutions to intersection problems, descriptions of the algorithms used in their design, and examples of practical applications of these algorithms.

Analysis and classification of multi-criteria decision-making methods
Authors:   Moscow State Technical University named after N.E. Bauman, Moscow, Russia, Chechnev V.B.
Published: November 2024

Decision-making requires in-depth analysis through the evaluation and comparison of various alternative solutions. These tasks are characterized by multiple criteria used for comparison. The variability of parameters and conditions in decision-making has led to the development of numerous methods aimed at facilitating this process effectively. Currently, several hundred multi-criteria decision-making methods are known, making it challenging to select the most appropriate one for practical use. Therefore, research on the analysis, classification, and systematization of multi-criteria decision-making methods is relevant and essential for decision-makers and developers of decision support systems. Most classifications emphasize the methodologies and purposes of these methods, often overlooking their inherent limitations. This article attempts to systematize the main multi-criteria decision-making methods, considering their limitations. It analyzes the most widely used methods and their classifications. Based on identified limitations, the paper proposes a classification of multi-criteria decision-making methods and guidelines for selecting them. Applying this approach can enhance the validity of method selection and, consequently, the effectiveness of the decisions made.

A combined adaptive optical system designed to correct the wavefront of light radiation distorted by the influence of strong atmospheric turbulence is presented. The system consists of a beam position stabilizer and a fast adaptive optical system operating in real time. Stabilization of the beam position is carried out by two electronically controlled tilt mirrors. The control loop includes two quadrant sensors and an FPGA (field-programmable gate array) that closes the feedback loop. Using information received from Shack-Hartmann wavefront sensor, a bimorph-based adaptive mirror, controlled by another FPGA, is able to compensate for wavefront aberrations for up to 23-th Zernike polynomial in real time. The system was tested under the laboratory turbulence conditions created by a fan heater. The bandwidth of the artificial turbulence in the experiments did not exceed 100 Hz, which corresponds to the average statistical state of the real atmosphere. Results of the correction of the wave front distorted by the artificial turbulence are presented. It is shown that when only a bimorph corrector is used, the value of wavefront tilt angles increases. This presents a certain problem, since a significant part of the turbulence energy falls on the wave front tilts. To address this problem, it is proposed additionally using a system for stabilizing the position of the light beam.

Published: November 2024

The purpose of this work is to describe two important types of limit sets of the most simple skew products of interval maps, the phase space of each of which is a compact n-dimensional cell (n ≥ 2): firstly, a non-wandering set and, secondly, ω-limit sets of trajectories. Methods. A method for investigating of a nonwandering set (new even for the two-dimensional case) is proposed, based on the use of the concept of C0-Ω-blow up in continuous closed interval maps, and the concept of C0-Ω-blow up introduced in the work in the family of continuous fibers maps. To describe the ω-limit sets, the technique of special series constructed for the trajectory and containing an information about its asymptotic behavior is used. Results. A complete description is given of the nonwandering set of the continuous simplest skew product of the interval maps, that is, a continuous skew product on a compact n-dimensional cell, the set of (least) periods of periodic points of which is bounded. The results obtained in the description of a nonwandering set are used in the study of ω-limit sets. The paper describes a topological structure of ω-limit sets of the maps under consideration. Sufficient conditions have been found under which the ω-limit set of the trajectory is a periodic orbit, as well as the necessary conditions for the existence of one-dimensional ω-limit sets. Conclusion. Further development of the C0-Ω-blow up technique in the family of maps in fibers will allow us to describe the structure of a nonwandering set of skew products of one-dimensional maps, in particular, with a closed set of periodic points defined on the simplest manifolds of arbitrary finite dimension. Further development of the theory of special divergent series constructed in the work will allow us to proceed to the description of ω-limit sets of arbitrary dimension d, where 2 ≤ d ≤ n - 1, n ≥ 3, in the simplest skew products.

Authors: Cambaza Edgar Manuel , Gustavo Filipe Francisco Gerente , Cuata Sebastião Job , Jamal Rajabo Victorino
Published: November 2024

This article explores the ethical implications of multilevel marketing (MLM) in the dietary supplement sector, analyzing issues of transparency, fairness, and the exploitation of consumers and distributors. The objective is to assess MLM through the lens of bioethics, focusing on the principles of autonomy, beneficence, non-maleficence, and justice. The methodology involves a systematic literature review using Atlas.ti software to categorize themes related to unfounded health claims, recruitment practices, and the exploitation of vulnerable groups. The main findings indicate that the current MLM model favors an elite, leaves most distributors at a financial disadvantage, and compromises consumer autonomy and health by selling products with unproven benefits. The conclusion highlights that as it currently operates, MLM does not meet fundamental ethical principles and requires significant adjustments. Recommendations include increased company transparency, stricter regulations, and ethical alternatives such as eliminating recruitment-based structures.
