Smart Yoga Assistant: SVM-based Real-time Pose Detection and Correction System
No full textSVM-based Real-time Pose Detection and Correction System refer to a computer system that uses machine learning techniques to detect and correct a person's yoga pose in real-time. This system can act as a virtual yoga assistant, helping people improve their yoga practice by providing immediate feedback on their form and helping to prevent injury. This paper presents a yoga tracker and correction system that uses computer vision and machine learning algorithms to track and correct yoga poses. The system comprises a camera and a computer vision module that captures images of the yoga practitioner and identifies the poses being performed. The machine learning module analyzes the images to provide feedback on the quality of the poses and recommends corrections to improve form and prevent injuries. This paper proposed a customized support vector machine (SVM) based real-time pose detection and correction system that suggests yoga practices based on specific health conditions or diseases. Paper aims to provide a reliable and accessible resource for individuals seeking to use yoga as a complementary approach to managing their health conditions. The system also includes a practitioner’s interface that enables practitioners to receive personalized recommendations for their yoga practice. The system is developed using Python and several open-source libraries, and was tested on a dataset of yoga poses. The hyper parameter gamma tuned to optimize the classification accuracy on our dataset produced 87% which is better than other approaches. The experiment results demonstrate the effectiveness of the system in tracking and correcting yoga poses, and its potential to enhance the quality of yoga practice
A humanist key from the mid-15th century to the humanism of the Crown of Aragon from the late 14th century: Ferran Valenti and the Preface to his translation of Cicero’s Paradoxa
No full textIn this article I study the Preface by Ferran Valentí to his own translation into Catalan of Cicero’s Paradoxa. Ferran Valentí was a humanist from Majorca, author in Catalan language who earned a Low Degree at the University of Bologna and who declared himself a devoted “son and pupil” of humanist Leonardo Bruni. Valentí made an analysis of the humanistic Canon in mid-15th century, including troubadours, Dante, Lullius, Latin literature classics and several Catalan authors, such as Bernat Metge. This proves that humanism was a true trend in the Crown of Aragon from the 2nd half of the 14th Century on.Artículo en el seno del centro y proyectos de investigación siguientes: ISIC-IVITRA (ISIC/2012/022), PROMETEO/2009/042; FFI2012-37103; GITE-09009-UA; VIGROB-125
A Systematic Literature Review on Diabetic Retinopathy Using an Artificial Intelligence Approach
No full textDiabetic retinopathy occurs due to long-term diabetes with changing blood glucose levels and has become the most common cause of vision loss worldwide. It has become a severe problem among the working-age group that needs to be solved early to avoid vision loss in the future. Artificial intelligence-based technologies have been utilized to detect and grade diabetic retinopathy at the initial level. Early detection allows for proper treatment and, as a result, eyesight complications can be avoided. The in-depth analysis now details the various methods for diagnosing diabetic retinopathy using blood vessels, microaneurysms, exudates, macula, optic discs, and hemorrhages. In most trials, fundus images of the retina are used, which are taken using a fundus camera. This survey discusses the basics of diabetes, its prevalence, complications, and artificial intelligence approaches to deal with the early detection and classification of diabetic retinopathy. The research also discusses artificial intelligence-based techniques such as machine learning and deep learning. New research fields such as transfer learning using generative adversarial networks, domain adaptation, multitask learning, and explainable artificial intelligence in diabetic retinopathy are also considered. A list of existing datasets, screening systems, performance measurements, biomarkers in diabetic retinopathy, potential issues, and challenges faced in ophthalmology, followed by the future scope conclusion, is discussed. To the author, no other literature has analyzed recent state-of-the-art techniques considering the PRISMA approach and artificial intelligence as the core
Face Liveness Detection Using Artificial Intelligence Techniques: A Systematic Literature Review and Future Directions
No full textBiometrics has been evolving as an exciting yet challenging area in the last decade. Though face recognition is one of the most promising biometrics techniques, it is vulnerable to spoofing threats. Many researchers focus on face liveness detection to protect biometric authentication systems from spoofing attacks with printed photos, video replays, etc. As a result, it is critical to investigate the current research concerning face liveness detection, to address whether recent advancements can give solutions to mitigate the rising challenges. This research performed a systematic review using the PRISMA approach by exploring the most relevant electronic databases. The article selection process follows preset inclusion and exclusion criteria. The conceptual analysis examines the data retrieved from the selected papers. To the author, this is one of the foremost systematic literature reviews dedicated to face-liveness detection that evaluates existing academic material published in the last decade. The research discusses face spoofing attacks, various feature extraction strategies, and Artificial Intelligence approaches in face liveness detection. Artificial intelligence-based methods, including Machine Learning and Deep Learning algorithms used for face liveness detection, have been discussed in the research. New research areas such as Explainable Artificial Intelligence, Federated Learning, Transfer learning, and Meta-Learning in face liveness detection, are also considered. A list of datasets, evaluation metrics, challenges, and future directions are discussed. Despite the recent and substantial achievements in this field, the challenges make the research in face liveness detection fascinating
Rare or Rarely-Used PUs as Descriptors of Literary Style. Aspects of Ausiàs March´s UFs Based on Corpus Linguistics and Translations
No full textPaying attention to the frequency of use is also a key aspect in the characterization of literary style. In this case, the linguistic resources utilized by authors are important because they contextualize them within their time, context, and cultural movement. Rare linguistics elements are not less relevant, that is those used only by one or a few authors. We analyze examples that confirm the methodological relevance of Corpus Linguistics, translation and analysis of PUs so that we can better understand what makes Catalan classics unique in what referes to their verbal art. To do so, we focus on UPs –[verbal] locutions– with rare occurrences and in some cases with only 1 or 2 occurrences (or up to 5, always in a few authors or even in one single author). We have analyzed examples of single (or rare) occurrences of the great Valencian poet Ausiàs March.This study was done at the Institut Superior d’Investigació Cooperativa IVITRA [ISIC-IVITRA] (Programa per a la Constitució i Acreditació d’Instituts Superiors d’Investigació Cooperativa d’Excel∙lència de la Generalitat Valenciana, Ref.

On Angels and Demons. Analysis of a sequence in the iconographic programme of the encyclopedic moralization of fin´amors in Matfré Ermengaud´s Breviari d´Amor
No full textEn el present treball parem esment a 3 il·luminacions del Breviari d’Amor de Matfré Ermengaut que són ben eloqüents –valga la sinestèsia: imatges que són eloqüents— de la vocació d’Ermengaut en pro de la cristianització de la fin’amors. A més, estableixen una mena de seqüència en el concert de diàleg entre història natural, història sagrada i atenció a l’amor, als amadors, a fi i efecte que estableix qui és el receptor concret de l’obra, qui el model a seguir (els àngels) i qui a defugir (el dimoni), i quin és l’àmbit d’actuació del «maligne» : la societat cortés, ecosistema de la fin’amor.This paper analyzes three illuminations of Matfré Ermengaud´s Breviari d´Amor which represent the author´s attempt to Christianize the concept of fin´amors. In particular, they establish a connection among natural history, sacred history and love and lovers and allow us to study who is the recipient of Ermengaud´s work. In addition, they serve us to study the author´s injunctions on the model to be followed (angels), the model to reject (demons), and the sphere of action of «the evil» : courtly society and the ecosystem of fin´amors.Aquest estudi s’ha desenvolupat al si de l’Institut Superior d’Investigació Cooperativa IVITRA [ISIC-IVITRA] de la Generalitat Valenciana (Programa de la Generalitat Valenciana per a la Constitució i Acreditació d’Instituts Superiors d’Investigació Cooperativa d’Excel·lència [Ref.

Problematic Smartphone Use in Spanish and Italian University Students
No full textSustainable education requires the proper usage of technological devices. Among these is the smartphone, which is used by millions of young people around the world in today’s society. The objective of this study was to understand the smartphone usage profile of Spanish and Italian university students. It also aimed to identify possible problematic uses, and the differences in smartphone use (or abuse) between the participating subjects. The study was descriptive and comparative, with the intentional sampling of N = 1412 subjects studying at the education faculties of the University of Alicante (UA) and the Suor Orsola Benincasa University (UNISOB). A previously-validated questionnaire with 27 items was employed during the 2019–20 academic year. The data was analysed using the SPSS 25 programme. Descriptive and inferential analyses were carried out. The results obtained after the analysis of the data indicated that, of the four possible user types—occasional, habitual, at risk, and problematic—more than half of the sample identified themselves as habitual users. It can be concluded that there are significant differences between the universities: the UA students exhibited more problematic use than the UNISOB students. It is therefore necessary to prepare training programmes that are designed to avert problematic behaviours related to smartphone use.This work was supported by the Program Redes-I3CE of the Deputy Vice-Chancellor’s Office for Quality and Innovation of the University of Alicante, under Grant 4676—Smartphones as a resource for initial teacher training.

Principio europeo di non discriminazione religiosa e approcci nazionali alla “neutralità” del pubblico dipendente
No full textPrinciple of non-discrimination on the grounds of religion in EU law and national approaches to the "neutrality" of the public employee
ABSTRACT: For the first time, the Court of Justice of the European Union has been called upon to give a preliminary ruling on prohibition on wearing visible signs of political, philosophical or religious belief imposed by a public employer, from the perspective of the principle of non-discrimination on the grounds of religion enshrine in the Council Directive 2000/78/EC of 27 November 2000 (establishing a general framework for equal treatment in employment and occupation). After a look at principles of State neutrality in France, Germany and Belgium, the paper examines this issue by taking a cue from the Conclusions presented by the Advocate General in case C‑148/22. According to the Author, national identity, to which Article 4(2) TEU refers, leaves in this particular sector a wide margin of discretion to the Member States.

Kids’ Emotion Recognition Using Various Deep-Learning Models with Explainable AI
No full textHuman ideas and sentiments are mirrored in facial expressions. They give the spectator a plethora of social cues, such as the viewer’s focus of attention, intention, motivation, and mood, which can help develop better interactive solutions in online platforms. This could be helpful for children while teaching them, which could help in cultivating a better interactive connect between teachers and students, since there is an increasing trend toward the online education platform due to the COVID-19 pandemic. To solve this, the authors proposed kids’ emotion recognition based on visual cues in this research with a justified reasoning model of explainable AI. The authors used two datasets to work on this problem; the first is the LIRIS Children Spontaneous Facial Expression Video Database, and the second is an author-created novel dataset of emotions displayed by children aged 7 to 10. The authors identified that the LIRIS dataset has achieved only 75% accuracy, and no study has worked further on this dataset in which the authors have achieved the highest accuracy of 89.31% and, in the authors’ dataset, an accuracy of 90.98%. The authors also realized that the face construction of children and adults is different, and the way children show emotions is very different and does not always follow the same way of facial expression for a specific emotion as compared with adults. Hence, the authors used 3D 468 landmark points and created two separate versions of the dataset from the original selected datasets, which are LIRIS-Mesh and Authors-Mesh. In total, all four types of datasets were used, namely LIRIS, the authors’ dataset, LIRIS-Mesh, and Authors-Mesh, and a comparative analysis was performed by using seven different CNN models. The authors not only compared all dataset types used on different CNN models but also explained for every type of CNN used on every specific dataset type how test images are perceived by the deep-learning models by using explainable artificial intelligence (XAI), which helps in localizing features contributing to particular emotions. The authors used three methods of XAI, namely Grad-CAM, Grad-CAM++, and SoftGrad, which help users further establish the appropriate reason for emotion detection by knowing the contribution of its features in it
Language in Carmelina Sánchez Cutillas’ narrative work: towards the construction of a reference model in Valencian Country
No full textAquest article descriu el model lingüístic en la prosa de Carmelina Sánchez-Cutillas per mitjà de l’anàlisi d’alguns usos fonortogràfics, morfosintàctics i lèxics extrets de Matèria de Bretanya i del relat curt «El llamp i la sageta de records». La conjuntura historicosocial en què l’autora publicà ambdós textos i l’èxit que ha tingut Matèria de Bretanya entre el públic lector valencià justifiquen la pertinència d’examinar les tries lingüístiques de l’escriptora. Tal com es prova de demostrar, Sánchez-Cutillas opta per fer servir un model que incorpora a la llengua comuna formes valencianes prestigiades pels usos cultes i algun dialectalisme de la comarca de la Marina Baixa, sense renunciar, però, a la màxima convergència amb la resta de parlars del domini lingüístic. En general, el model de l’escriptora coincideix amb el que propugnaven alguns dels gramàtics i dels lletraferits valencians de l’època, com ara Sanchis Guarner o Enric Valor.This paper describes the linguistic model in Carmelina Sánchez-Cutillas’ prose by means of the analysis of some morphosyntactic, lexical and phonetical spelling uses taken from Matèria de Bretanya and from the short story «El llamp i la sageta de records». The historical-social context in which the author published both texts and the success achieved by Matèria de Bretanya among valencian readers justifies the relevance of examining the linguistic choices of the writer. As we aim at proving, Sánchez-Cutillas chooses to use a model that includes in standard language Valencian forms enjoying prestige due to their learned uses and some dialectisms form the region of the Marina Baixa, without giving up the maximum rapprochement with the rest of local ways of speaking within the linguistic domain. Generally speaking, the model of this writer coincides with that supported by some Valencian grammarians and literary figures of that time, such as Sanchis Guarner or Enric Valor.Aquest estudi ha estat desenvolupat al si de l’Institut Superior d’Investigació Cooperativa IVITRA [ISIC-IVITRA] de la Generalitat Valenciana (Programa de la Generalitat Valenciana per a la Constitució i Acreditació d’Instituts Superiors d’Investigació Cooperativa d’Excel·lència [Ref.
