Concept of Integrating a Hybrid Thermal Error Compensation Into an Existing Machine Tool Control Architecture
Authors: Geist Alexander , Yaqoob Muhammad Faisal , Friedrich Christian , Naumann Christian , Ihlenfeldt Steffen
Published: September 2024

Thermal error compensation via a numeric control (NC) system is a proven option for upgrading the precision of machine tools. The main advantage is the generally cost-effective application, as no changes to the machine design are necessary. Since modern machine tools are equipped with standard numeric controls along with additional functions and integrated temperature sensors in the machine, compensation methods such as a characteristic diagram (CD) based compensation can be implemented. To increase the applicability and reliability of this CD regression method, a hybrid model approach with a virtual thermo-elastic finite element (FE) machine model and a real-time computable structural model of a machine tool was developed. The structural model uses model order reduction to calculate the current load case in real-time using continuously recorded machine data (motor current, axis position, temperatures). It acts as a virtual monitoring application to check, whether the current machine condition still matches the current CD based prediction. If the current load case is not suitable to the active CDs or any other stored CDs, the generation of new CDs is automatically triggered. In this article, the integration of the hybrid compensation method using an FE model and a structural model of a machine tool is methodically demonstrated. The main focus is on the integration of different software and hardware architectures and their interaction.
État de l'art sur les déchets diffusés abandonnés en milieu urbain et transférés via les réseaux pluviaux
Authors: Ledieu Lauriane , Tramoy Romain , Bruttin Clémence , Tassin Bruno , Gasperi Johnny
Published: September 2024

Les environnements terrestres ont récemment été désignés comme la source principale de la pollution plastique liée aux milieux aquatiques (rivières, océans, etc.), mais peu d'études étayent cette hypothèse. La problématique des déchets abandonnés sur les surfaces urbaines et transférés via les réseaux pluviaux est pourtant une problématique de longue date, mais souvent laissée aux collectivités et/ou associations, sans réelle implication de la recherche scientifique. Cette synthèse a pour objectifs de recenser les données existantes sur les densités de déchets abandonnés sur l'espace urbain, sur les flux transférés
dans les réseaux pluviaux et sur les facteurs qui déterminent leurs variabilités spatiotemporelles. Elle vise également à exposer les typologies des déchets observés. Il ressort de cette synthèse que l'importante variabilité à la fois des méthodes utilisées et des modalités d'expression des résultats rend difficile la comparaison des études et la généralisation des résultats. Les études indiquent des densités de déchets, plastiques surtout, de l'ordre de quelques dizaines à plusieurs centaines de milliers de déchets/km² sur les surfaces urbaines. Ces densités ont d'importantes variabilités spatiotemporelles dont les facteurs restent peu identifiés par manque de standardisation dans les paramètres pris en compte. Dans les eaux pluviales urbaines, les flux quantifiés sont conséquents et entraînent une contribution majeure de cette source dans la pollution des milieux hydrologiques récepteurs. Mais cette contribution est difficile à appréhender parce que différentes approches sont utilisées pour normaliser les flux quantifiés (rapportés au nombre d'habitants, à la surface drainée ou à la surface imperméabilisée) et que de nombreuses variables peu considérées (climat, propreté, types de réseaux…) sont susceptibles de jouer un rôle. Des solutions préventives telles que les actions des services de nettoyage et la présence d'avaloirs sélectifs apparaissent néanmoins efficaces pour limiter le transfert des macrodéchets vers les milieux aquatiques récepteurs.
Exploring public opinions on Rohingya refugees residing in India: An empirical study
Authors: Verma Monika , Kironska Kristina
Published: September 2024

The Rohingya population is widely acknowledged as one of the most persecuted minority groups worldwide. The ongoing tripartite conflict involving the Rohingya, the Rakhine, and the Myanmar military has resulted in numerous clashes and massacres, leading to forced displacement. Countries such as Bangladesh, Thailand, Malaysia, Indonesia, the Philippines, Pakistan, and India have recorded an influx of Rohingya immigrants. While extensive studies have been conducted on the Rohingya in Myanmar and Bangladesh, there has been a limited scholarly focus on the Rohingya in India. This article aims to fill this gap in the literature. It is important to note that India is neither a signatory to the 1951 Refugee Convention nor the 1967 Protocol, which addresses refugee status and protections, nor does it have a domestic refugee law. Consequently, refugees in India are not officially recognized as a distinct group and lack legal protection against exploitation and abuse. This situation leaves them vulnerable to various forms of mistreatment, including exploitation, violence, and limited access to employment, education, and healthcare. Although the United Nations High Commissioner for Refugees designates the Rohingya as refugees, the current Bharatiya Janata Party government views this stateless community as illegal migrants and a perceived threat to India. This stance raises important questions: (i) How does the Indian population perceive and internalize this interpretation? (ii) What are their attitudes toward the Rohingya, and what policy options do they prefer? To address these inquiries, the authors of this article analyzed data from the Sinophone Borderlands Indo-Pacific Survey, a large-scale online survey organized by one of the authors. In addition, interviews were conducted with Rohingya individuals residing in India to gather firsthand perspectives.
Turkish and English translations of Annie Ernaux’s Les Années as an “impersonal autobiography”
Authors: Sancaktaroğlu Bozkurt Sinem , Gökduman Umut Can
Published: September 2024

This study conducted at the intersection between literary studies and translation studies, examines the Turkish and English translations of French novel Les Années by Annie Ernaux, which was published in 2008. It is argued that in this “impersonal autobiography”, the author has in a sense transformed, in other words metaphorically self-translated, her own life into a narrative by blending it with social elements and cultural and period-specific references. Then, the novel written by Ernaux as a result of a mental translation process is translated into other languages, and the characteristic features of this “impersonal autobiography” are likely to create translation challenges specific to the genre. In addition, the fact that the novel is considered as a metaphorical translation can contribute to these translation challenges. As a result of the analysis of metaphorical and interlingual translations and an examination of paratexts, it is found that the preferred translation strategies employed in different translations contribute to the repositioning of this impersonal autobiography in English and Turkish.
ÜMİT YAŞAR OĞUZCAN’IN HİCİVLERİNDE METİNLERARASILIK
Authors: Şahin Dursun
Published: September 2024

Bir metnin doğrudan veya dolaylı bir biçimde başka metinlerle kurmuş olduğu ilişkiler esasına dayanan metinlerarasılık, kaynağını Mikhail Bakhtin’in söyleşimcilik (dialogism) kuramından almaktadır. Cumhuriyet dönemi Türk şiirinin, metinlerarası ilişkiler bağlamında incelendiğinde, canlı ve zengin bir birikime sahip olduğu görülür. Bunda çağdaş Türk şiirinin; Batı edebiyatı, halk edebiyatı, Divan edebiyatı gibi pek çok kaynaktan beslenmesinin büyük etkisi vardır. Çağdaş Türk şiirinin önemli isimlerinden biri olan Ümit Yaşar Oğuzcan da şiirlerinde metinlerarasılığa önem veren isimlerden biridir. Kendini hiciv şairi olarak gören Oğuzcan’ın hiciv şiirleriyle sınırlı olan bu çalışmada şiirler, metinlerarası unsurlar açısından ele alınmıştır. Doküman analizi yöntemiyle hazırlanan bu çalışmayla Oğuzcan’ın geçmişe hâkim bir şair olduğu, hicivlerinde metinlerarası unsurlara bilinçli bir şekilde bolca yer verdiği tespit edilmiştir. Şairin hicivlerinin metinlerarası unsurlardan “gönderme (atıf)”, “anıştırma”, “öykünme (pastiş)”, “yansılama (parodi)” ve “yeniden yazma” açısından oldukça zengin olduğu; hicivlerde alıntı, montaj ve kolaja ise yer verilmediği tespit edilmiştir. Ümit Yaşar Oğuzcan’ın eserlerinden bazılarının yasalara aykırı olarak internet ortamına yüklenmesi nedeniyle, eserlerden alınan örnekler benzerlik oranını yükselttiği için çalışmada sınırlı ölçüde örnek verilebilmiştir.
Tanrısız Gençlik Romanında Kara Eğitim
Authors: Güven Emre Bekir
Published: September 2024

Eğitim, tarihsel süreci boyunca insanlığın önem verdiği olgular arasında yer almıştır. Uygar coğrafyalar yakından incelendiğinde, temellerinde güçlü bir eğitimin olduğu görülebilir. Nesnel ölçütler çerçevesinde daha geride konumlanan coğrafyalarda ise eğitime dair eksiklik, aksaklık veya müdahaleler göze çarpmaktadır. Eğitimin bu açıdan belirleyici olan işlevine rağmen bazı zaman ve coğrafyalarda, güç otoriteleri eğitime çeşitli müdahalelerde bulunmaktan geri durmamışlardır. Bunlara dair bir örnek de 1933 ile 1945 arasında hüküm süren nasyonal sosyalist Alman idaresidir. Nasyonal sosyalist ideoloji doğrultusunda genç bireyler başta olmak üzere, topluma karşı uygulanan eğitim, geleneksel ve genelgeçer anlamından farklı bir doğrultuda şekillenmiştir. Belirlenmiş ve arzu edilen insan profiline yönelik nasyonal sosyalist otoritelerin fikri ve fiziki müdahalesi, eğitimi “kara” kılmıştır. Özellikle genç bireylerin gerek psikolojik gerekse fiziksel açılardan kara eğitime maruz bırakılması, edebi yapıtlara da konu olmuştur. Bu yapıtlara nitelikli bir örnek, Ödön von Horvath’ın Tanrısız Gençlik (Jugend ohne Gott) romanıdır. Horvath, yapıtında isim vermeksizin Adolf Hitler ve nasyonal sosyalistlerin eğitim politikalarına dair güçlü verilere yer vermiştir. Bu politikaların sonucu olarak başta genç bireyler olmak üzere, farklı profilde figürlerin dönüştüğü varlıklar ve başvurduğu eylemler romanda açıkça gösterilmektedir.
Bu çalışma Horvath’ın Tanrısız Gençlik romanında kara eğitime dair verileri irdelemektedir. Çalışmanın amacı, Hitler önderliğinde nasyonal sosyalist ideoloji güdümündeki eğitimin edebi bir yapıta ne şekilde yansıdığını göstermektir.

In 2014, Nigeria was largest and fastest growing economy in Africa, and this is determine by year on year Gross Domestic Product (GDP), which is the major tools use by the rest of the world to determine the capacity of a country. Furthermore National Bureau of Statistics (NBS) releases both quarterly and yearly growth of Nigeria GDP, while the data source in this project is from NBS, starting from 1980 to 2017. Moreover the Nigeria GDP comprises many components. The major PCs use are Agriculture, Building and Construction, Industry, Wholesale and Retail Trade, and Services. It was observed that there is yearly growth in Nigeria gross domestic products due to increase in all contributors factored components from 1980 to 2017, Agriculture had the highest number activities to this per capital income followed by Industry, Services, wholesale and retail trade, and building and construction. Also the overall accumulated variance for the GDP for the studied period is 10.7 for a 56% coefficient of variation. All the contributors (Agriculture, Industry,......) maintained a positive correlation all through the period of study expect for Services that affect/shirk the GDP along the year. Wholesales experienced the strongest doling of taking care of the GDP with 98%, followed by Building and Construction, industry and agriculture with 86%, 78% and 6% respectively. However for Nigeria to maintain the largest economy in Africa It will strongly advice that the economy team should look properly on agriculture and industry and if this two increases certainly wholesale and retail trade with building and construction will be affected positively while extended to services, therefore the GDP will also be stabilise.
Assessment of the Availability and Accessibility to Improved Cassava Varieties by Smallholder Farmers in Siaya County, Kenya
Authors: Anyango Dorine , Andika Darius , Ouma Matilda
Published: September 2024

Cassava is significantly important as a staple food in numerous sub-Saharan regions. It is the third most vital calorie source and the second most crucial tuber crop. Cassava is capable of withstanding difficult growing conditions thus a suitable climate smart crop for arid and semi-arid areas. Globally, Nigeria produces the highest amount of cassava. In Kenya production stands at 1 million metric tons against a potential of 3 million metric tons annually. Western region contributes 60% of total Kenyan cassava. Unlike other staple food crops with a well-structured formal seed system, cassava with an informal seed system experiences several challenges including lack of access to improved varieties. A cross sectional research design was used with purposive sampling. Data was collected using a semi-structured questionnaire on a face to face interview. A total of 72 smallholder cassava farmers were selected using Cochran’s formula. Chi-square test, logistics regression and Spearman’s correlation were used to analyze the data, with the help of SPSS version 20. The results showed that 72.2% of the smallholder farmers had access to improved cassava varieties. Significant differences were observed between socio-demographic factors (age, education level, household head, marital status, total land size, land ownership, household head occupation, credit access, farmer group and training) on access to improved cassava varieties. However, seeds were of low quality and unclean as they were borrowed from fellow farmers. The recommendation is to discourage over dependence on free seed and sensitize farmers on the importance of purchasing high quality seed.

Published: September 2024

Authentic determination of evidence of students’ academic achievement is demonstrated in the best way by using a table of specification in which this study aimed at making its focus. Thus, study sought to investigatethe extent that history teachers prepare table of specification in enhancing academic achievements in public secondary schools in Mwanga district, Tanzania. Anchored on Validity theory, proposed by Messick in 1989, the study employed a convergent design under mixed methods approach to collect information from target population of 144 history teachers, 135 school quality assurers, 27 heads of school, 27 heads of history department, 1 chief quality assurer and 1 district secondary education officer made a total of 308 respondents. Sample size has total of 150 respondents that comprised 69 history teachers, 16 heads of schools, 16 heads of history department, 1 chief quality assurer and 48 school internal quality assurers that were selected through stratified and simple random sampling techniques. The study used questionnaire to obtain quantitative data from history teachers and school internal quality assurers and interview guide to acquire qualitative data from chief quality assurer. The study also used interview schedule to obtain the information from the history head of departments and school internal quality assurers. Validity of instruments was established through research experts in assessment and evaluation in the faculty of education from Mwenge Catholic University. Cronbach Alpha technique was used to establish the reliability of the Likert type items constituted in the questionnaires at a coefficient of 0.820. Dependability of qualitative data collection instruments was ensured through triangulation and peer debriefing. The study adhered to research ethical issues such as: signing consent forms, confidentiality, anonymity, and citation and referencing to avoid plagiarism. The study revealed that: history teachers in public secondary schools prepare and use table of specifications to outline the topics and skills to be assessed in exams or assignments to the low extent. The study concludes that, history teachers in public secondary schools do not prepare and use table of specification to outline the topics and skills to be assessed in exams or assignments and hence they fail to consider cognitive levels of learning. The study recommends to the District Chief Quality Assurer to create awareness to history teachers on viability of the preparation and usability of the table of specifications to ensure validity of testing and assessment procedures. The study also recommends that, heads of history department should ensure that history teachers prepare and use table of specifications during the entire assessment process to ensure students’ higher academic achievements.
Anatomical and Pathological Review of Alzheimer's, Huntington's, and Pick's Disease: A Public Study on the Awareness of Neurological Disorders
Authors: Vipin Katoch Sujay
Published: September 2024

Neurodegenerative diseases (NDDs) include Alzheimer's disease, Parkinson's disease, Amyotrophic Lateral Sclerosis (ALS), Huntington's Disease, and Pick's disease. These conditions are characterized by a progressive decline in the structure and function of the nervous system. The objective of this paper is to provide a brief overview of these diseases, outline the anatomical changes they cause in the brain, and evaluate the level of public awareness about their prevalence and impact. Neuroimaging studies show that Alzheimer's disease initially leads to the degeneration of neuronal connections in brain regions associated with memory, such as the entorhinal cortex and hippocampus. ALS is characterized by the degradation of motor neurons in the spinal cord and brainstem, leading to muscle weakness and atrophy. In contrast, Parkinson's disease involves the decay of dopaminergic neurons in the substantia nigra, resulting in motor control impairments. Brain structure changes are linked to the accumulation of abnormal protein aggregates such as amyloid beta in Alzheimer's disease and alpha-synuclein in Parkinson's disease, interfering with cellular functions and causing neuronal death. Besides addressing brain structure, this paper presents results from a survey assessing public awareness of neurodegenerative diseases. The findings suggest that while the public is well-informed about Alzheimer's and Parkinson's disease, there is still a significant knowledge gap regarding less common conditions like ALS and Huntington's disease. The significance of implementing thorough educational approaches to increase public knowledge is highlighted by these results. This study seeks to narrow the divide between scientific knowledge and public awareness of neurodegenerative diseases by combining anatomical understanding with public perceptions.
A Review on Validated RP-HPLC Method for the Simultaneous Estimation of Serdexmethylphenidate and Dexmethylphenidate in Bulk and Pharmaceutical Dosage Form
Authors: Reddy A.Raja , Shepherd L. Noel
Published: September 2024

An ADHD medication called Azstarys was approved by the FDA in March 2021.Because it combined serdexmethylphenidate and dexmethylphenidate for the first time, it is unique. Treatment for Attention Deficit Hyperactivity Disorder (ADHD) begins with a prodrug called serdexmethylphenidate. CNS stimulants include serdexmethylphenidate. People six years of age and older with attention deficit hyperactivity disorder (ADHD) are taken serdexmethylphenidate, a prodrug of dexmethylphenidate, in addition to dexmethylphenidate. Serdexmethylphenidate is a prodrug of the central nervous system stimulant dexmethylphenidate. It alters neurotransmission in the central nervous system by increasing extracellular dopamine and norepinephrine numbers.3[11] As a central nervous system stimulant, serdexmethylphenidate carries a risk of usage, addiction, and abuse that should be monitored. In addition, patients need to be assessed. The accuracy, precision, linearity, robustness, limits of detection and quantitation, system adaptability, robustness, and other factors can all be used to validate the RP-HPLC technology.
Analytique du lien, analytique du lieu
Authors: Allouch Jean
Published: September 2024

De même que Platon, Foucault, Rubin, Jacques Lacan a discrètement distingué deux analytiques du sexe. On explore ici cette veine en montrant que l’une est focalisée sur le lien à l’objet, l’autre sur le lieu. Il devait en être ainsi dès lors que, l’Autre étant reconnu inexistant, l’idée d’un rapport sexuel avec lui était écartée. Jugés essentiels à la pratique analytique contemporaine certains concepts se présentent alors comme n’allant plus de soi : l’image, le fantasme, le traumatisme, la sexualité. Ils sont ici revisités. Il l’aura fallu alors que, tournant le dos à Freud, Lacan déclarait que la chose freudienne a pour propriété d’être asexuée.
L’origine de la horde primitive
Authors: Monnier David
Published: September 2024

L’auteur revient sur une référence méconnue de Charles Darwin reprise par Sigmund Freud dans Totem et tabou : l’article princeps de Thomas Savage sur le gorille. Il établit la façon dont Darwin s’en sert pour proposer ses hypothèses sur l’origine de l’homme. Il montre que Darwin prend en considération le mode de vie des gorilles mais aussi celui d’autres espèces animales ainsi que des hommes actuels. Darwin l’insère dans les débats sur la loi du combat, la polygamie, la sélection sexuelle, l’interdit de l’inceste, la descendance. Puis l’auteur fait valoir que Freud reprend Darwin dans une perspective toute différente pour concevoir l’accès humain à la culture, où la représentation du gorille conserve une importance.

Published: September 2024

Cet article interroge la nature des deux institutions liées à la naissance de l’opéra français : l’Académie d’opéras, créée par Pierre Perrin en 1669, dont Jean-Baptiste Lully rachète le privilège en 1672, fondant l’Académie royale de musique. Dans la diversité de leur fonctionnement et de leur finalité, les deux académies sont le fruit d’un croisement entre le modèle de l’opéra de cour de matrice italienne, pensé par et conçu pour une élite – les « connaisseurs » – et de nouvelles exigences commerciales imposées par une logique entrepreneuriale.
Liens entre la prise en charge, la psychothérapie et les facteurs déterminants dans les pratiques problématiques du chemsex , selon une expérience clinique
Authors: Grégoire Muriel
Published: September 2024

Le chemsex est l’usage de produits psychoactifs en contexte sexuel, quelle que soit la voie d’usage dans la population HSH, en vue d’augmenter le plaisir et d’améliorer les pratiques sexuelles. Les premiers chemsexeurs viennent dans les centres de soins addictologiques depuis une douzaine d’années. C’est à partir de ces rencontres que j’ai développé un type d’accompagnement qui s’est construit avec les usagers. Quelques techniques théoriques de base ont enrichi ces accompagnements thérapeutiques. Ce texte va expliciter le travail thérapeutique de suivi en CSAPA, avec les dimensions travaillées issues de ce travail et la description des facteurs spécifiques qui concourent à rendre cette pratique problématique, voire addictive.
La pratique du chemsex dans les enquêtes nationales Rapport au sexe (ERAS) auprès des hommes ayant des rapports sexuels avec des hommes : évolutions entre 2017 et 2023
Authors: Roux Perrine , Velter Annie
Published: September 2024

L’Enquête Rapport Au Sexe (ERAS) est une enquête en ligne transversale, auto-administrée et basée sur le volontariat, menée auprès des hommes ayant des rapports sexuels avec des hommes (HSH) ; quatre éditions ont été réalisées depuis 2017 (2019, 2021, 2023). L’article a pour objectif de décrire l’évolution de la pratique du chemsex au sein de ces enquêtes nationales et les caractéristiques des HSH qui le pratiquent à partir d’ERAS 2023. Depuis 2017, la pratique du chemsex est stable dans le temps, quel que soit l’indicateur utilisé. Celle au cours du dernier rapport sexuel s’élève à 5 % en 2017 et à 6 % en 2023 lors du dernier rapport sexuel et à 12 % en 2021 et 13 % en 2023 au cours des 6 derniers mois avant l’enquête. Par rapport aux participants qui ne pratiquent pas le chemsex, ceux qui le pratiquent sont plus souvent âgés de 25-45 ans, urbains, chômeurs, financièrement moins aisés ; attachés aux sociabilités et aux valeurs de performances sexuelles gay, séropositifs au VIH ou séronégatifs et usagers de la Prophylaxie pré-exposition (PrEP). Ils sont plus souvent multipartenaires et utilisent moins systématiquement le préservatif lors des pénétrations anales avec des partenaires occasionnels. La pratique du chemsex est associée à des comportements à haut risque de contamination au VIH et aux autres infections sexuellement transmissibles (IST) mais aussi à des signes de détresses psychosociales qui restent à explorer. Des services adaptés à la pratique du chemsex, répondant à la fois aux enjeux de réduction de risques, de santé sexuelle et de prise en charge psychosociale destinés aux HSH doivent être déployés afin d’assurer une prévention adaptée et des interventions en faveur du bien-être de cette population.
Évaluation de la santé sexuelle des hommes ayant des relations sexuelles avec d’autres hommes, suivis en consultations d’addictologie à Montpellier, pour un usage du chemsex
Authors: Ambrosino Marion , Donnadieu Hélène
Published: September 2024

Le chemsex désigne la consommation de substances psychoactives afin d’initier, faciliter, prolonger ou améliorer les rapports sexuels. La pratique concerne préférentiellement les hommes ayant des rapports sexuels avec des hommes (HSH). En France, ces substances sont principalement représentées par les cathinones de synthèse et le gamma-hydroxybutyrate (GHB). La visibilité de la pratique s’est largement accrue et diffusée sur le territoire au cours des dix dernières années, portée par internet et l’avènement des applications de rencontres géolocalisées. De nombreuses complications sont associées à cette pratique et sont largement décrites mais la santé sexuelle est peu abordée. Par conséquent, nous nous questionnons sur l’impact du chemsex sur la qualité de vie et la satisfaction sexuelle des usagers. Méthode. Étude observationnelle. Lors des consultations, le questionnaire MSHQ a été proposé aux usagers consultant pour un usage de chemsex. Les données socio-démographiques et les modalités de la pratique étaient également recueillies. Résultats. 22 participants interrogés, d’âge médian 36 ans. Les médianes des scores révèlent l’existence de perturbations érectiles et surtout éjaculatoires avec des scores médians s’élevant respectivement à 13/15 et 28/35. Les scores de gêne érectile et éjaculatoire vont également dans ce sens. Ce constat met à nouveau en lumière l’impact des substances et de la pratique sur la qualité de vie en santé sexuelle et la nécessité d’élaborer des questionnaires adaptés à cette population d’usagers.
Using a signal model for the Timing of Dividend Payment: the French case
Authors: Ben Letaifa Wissal
Published: September 2024

Fixer et publier la date de paiement des dividendes est une décision très importante dans le cycle de vie de l’entreprise. À notre connaissance, peu de méthode statistique ont tenté de résoudre ce problème à travers la littérature. Cette étude contribue à la littérature sur l’évaluation de la date de paiement des dividendes à travers les modèles de signaux. Nous utilisons un modèle de signal pour confirmer si la date de paiement du dividende peut être considérée comme un signal. Nous utilisons une base de données de 168 sociétés cotées commerciales et industrielles françaises entre 2003 et 2008. Notre résultat principal est : le moment de mise en paiement du dividende est utilisé comme un signal des dirigeants aux investisseurs car cette date est proche de la date de l’assemblée générale.

An innovative algorithm based on weighted fuzzy soft multisets and its application in selecting optimal construction materials
Authors: Korkmaz Esra
Published: September 2024

Effective decision-making is critical across various domains, including technology, medicine, and engineering. To address the complexities of decision-making, particularly in scenarios involving both positive and negative parameters, this paper introduces an innovative algorithm based on weighted fuzzy soft multisets. This algorithm mitigates the issue of counterintuitive results often encountered in existing methods. By incorporating the concept of uniform fuzzy soft multisets and considering the conditional structure of these sets, our approach advances the theoretical framework of decision-making while providing a practical tool for complex scenarios. To demonstrate its practical applicability, we conduct a case study focused on selecting optimal construction materials for a building project, utilizing data from established engineering standards and a comprehensive wood properties database. The key findings of our sensitivity analysis highlight the algorithm's robustness to weight changes and adaptability to different decision sequences. These findings highlight the algorithm's potential to enhance decision support systems across various fields, such as engineering, healthcare, and environmental management. This potential is particularly valuable in complex, multi-criteria scenarios that demand nuanced, context-aware solutions.
A new hybrid conjugate gradient method close to the memoryless BFGS quasi-Newton method and its application in image restoration and machine learning
Authors: Zhang Xiyuan , Yang Yueting
Published: September 2024

A new hybrid conjugate gradient algorithm for solving the unconstrained optimization problem was presented. The algorithm could be considered as a modification of the memoryless Broyden-Fletcher-Goldfarb-Shanno (BFGS) quasi-Newton method. Based on a normalized gradient difference, we introduced a new combining conjugate gradient direction close to the direction of the memoryless BFGS quasi-Newton direction. It was shown that the search direction satisfied the sufficient descent property independent of the line search. For general nonlinear functions, the global convergence of the algorithm was proved under standard assumptions. Numerical experiments indicated a potential performance of the new algorithm, especially for solving the large-scale problems. In addition, the proposed method was used in practical application problems for image restoration and machine learning.
Time-delayed control of a nonlinear self-excited structure driven by simultaneous primary and 1:1 internal resonance: analytical and numerical investigation

Published: September 2024

Main objective of this research to eliminate the resonant vibrations and stabilize the unstable motion of a self-excited structure through the implementation of an innovative active control strategy. The control strategy coupling the self-excited structure with a second-order filter, which feedback gain $ \lambda $ and control gain $ \beta $, as well as a first-order filter, which feedback gain $ \delta $ and control gain $ \gamma $. The coupling of the second-order filter to establish an energy bridge between the structure and the filter to pump out the structure's vibration energy to the filter. In contrast, the primary purpose of coupling the first-order filter to stabilize the closed loop by adjusting the damping of the system using the control keys $ \delta $ and $ \gamma $. Accordingly, the mathematical model of the proposed control system formulated, incorporating the closed-loop time delay $ \tau $. An analytical solution for the system model obtained, and a nonlinear algebraic system for the steady-state dynamics of the controlled structure extracted. The system's bifurcation characteristics analyzed in the form of stability charts and response curves. Additionally, the system's full response simulated numerically. Findings the high performance of the introduced controller in eliminating the structure's resonant vibrations and stabilizing non-resonant unstable motion. In addition, analytical and numerical investigations revealed that the frequency band within which the second-order filter can absorb the structure's resonant oscillation relies on the algebraic product of $ \beta $ and $ \lambda $. Furthermore, it was found that the equivalent damping of the system depends on the algebraic product of $ \gamma $ and $ \delta $, which can be employed to stabilize the negatively damped self-excited systems. Finally, it reported that although the loop delay can potentially degrade vibration control performance, the time-delay stability margin is nonlinearly proportional to the product of $ \gamma $ and $ \delta $. This finding that increasing the value of $ \gamma \times \delta $ can compensate for the adverse effects of loop delay on both system stability and vibration suppression efficiency.

In this paper, three new automorphisms were identified over the ring $ \mathbb{Z}_{4}+u\mathbb{Z}_{4}+u^{2}\mathbb{Z}_{4} $ where $ u^3 = u^2 $. With the help of these automorphisms, the characteristic structures of the generator polynomials for the $ \theta_i $-cyclic codes and $ (\theta_i, \lambda) $-constacyclic codes of odd length on this ring were investigated. Also, for all the units over the ring, $ \mathbb{Z}_{4} $-images of $ \theta_i $-cyclic and $ (\theta_i, \lambda) $-constacyclic codes were reviewed with the associated codes based on determined transformations. Using these observations, new and optimal codes were obtained and presented in the table. In addition, a new transformation was identified that involved DNA base pairs with the elements of $ \mathbb{Z}_{4} $. Moreover, a unit reverse polynomial was created, and in this way a new generation method has been built to construct reversible DNA codes over this ring. Finally, this article was further enhanced with supporting examples of the DNA as a part of the study.

Published: September 2024

The application of artificial intelligence provides opportunities to help in the curation and management of library collections to serve the user community better. Librarians are saddled with the responsibility of taking care of and maintaining information resources in the library collections. Curating and managing the library collections is an important task in the library system and can be daunting, from selection to ordering, acquiring selected information resources, processing these resources, stocktaking, and weeding. AI tools provide intelligent help in reducing time spent on repetitive functions and aid librarians in making informed decisions. Collection development librarians must understand the impact of AI tools in their section, make meaning from large datasets, devise metadata systems, and lay the proper framework for cataloguing and classifying these information resources. This ensures that the goal of the library is to provide its patrons with appropriate collections that meet the needs of the library's user community within its limited financial and human resources.

Assessing Global Interest in Financial Inclusion Information
Authors: Ozili Peterson K
Published: September 2024

This paper investigates the general level of interest in financial inclusion information using global data. Descriptive statistics and correlation analyses were used to assess the global interest in financial inclusion information. Using Google Trends monthly data from 2004 to 2021, the results show that the term ‘financial inclusion' was more popular on the web in year 2017 than in any other year. Secondly, the highest level of interest in the term ‘financial inclusion' by internet users was recorded in non-crisis months particularly after the global financial crisis but before the COVID-19 pandemic while the lowest interest in the term ‘financial inclusion' by internet users was recorded in crisis months particularly during the global financial crisis and during the COVID-19 period. Thirdly, web search for information about financial inclusion was more popular in Zimbabwe, Rwanda, Fiji, Uganda and Zambia, while news search for information about financial inclusion was more popular in Fiji, India, Malaysia, Kenya, Singapore and Nigeria. This suggests that there was more interest in the term ‘financial inclusion' among internet users in developing countries than in developed countries. Also, there is a negative correlation between interest in financial inclusion information and the level of country development.
