The Effect of Dual Hyperparameter Optimization on Software Vulnerability Prediction Models
Authors: Bassi Deepali , Singh Hardeep
Published: December 2022

Background: Prediction of software vulnerabilities is a major concern in the field of software security. Many researchers have worked to construct various software vulnerability prediction (SVP) models. The emerging machine learning domain aids in building effective SVP models. The employment of data balancing/resampling techniques and optimal hyperparameters can upgrade their performance. Previous research studies have shown the impact of hyperparameter optimization (HPO) on machine learning algorithms and data balancing techniques.

Aim: The current study aims to analyze the impact of dual hyperparameter optimization on metrics-based SVP models.

Method: This paper has proposed the methodology using the python framework Optuna that optimizes the hyperparameters for both machine learners and data balancing techniques. For the experimentation purpose, we have compared six combinations of five machine learners and five resampling techniques considering default parameters and optimized hyperparameters.

Results: Additionally, the Wilcoxon signed-rank test with the Bonferroni correction method was implied, and observed that dual HPO performs better than HPO on learners and HPO on data balancers. Furthermore, the paper has assessed the impact of data complexity measures and concludes that HPO does not improve the performance of those datasets that exhibit high overlap.

Conclusion: The experimental analysis unveils that dual HPO is 64% effective in enhancing the productivity of SVP models.

Published: December 2022

Background: Breast cancer has the highest incidence of all cancers in women worldwide. A molecular subtype of breast cancer, degree of differentiation, and lymph node metastasis are prognostic and predictive factors of breast cancer. This study aims to explore the relationship between molecular subtype, degree of differentiation, and lymph node metastasis with overall survival and disease-free survival of breast cancer patients at Dr. M. Djamil General Hospital Padang.

Methods: This study was an analytic observational study with a retrospective cohort approach using secondary data from 68 subjects. The test variables in this study were the molecular subtype of breast cancer, the degree of differentiation, and lymph node metastasis which were obtained from secondary data and medical records. Another test variable is patient survival, namely overall survival (OS) and disease-free survival (DFS). Data analysis with the help of SPSS software in univariate, bivariate, and multivariate.

Results: Patients with lymph node metastases were 7.94 times more likely to experience an event (death) (HR=7.94 95% CI: 0.91–78.2). Patients with lymph node metastases were 10.2 times more likely to experience an event (recurrence) (HR=10.2 95% CI: 1.03–101.1).

Conclusion: Lymph node metastases are the factors most related to survival (overall survival and disease-free survival) of breast cancer patients at Dr. M. Djamil General Hospital, Padang, Indonesia.
The Chinese Civil Examinations
Authors: De Weerdt Hilde
Published: December 2022

From the end of the sixth century onwards the written civil service examinations became a staple of life in Imperial China. These examinations were used, among other things, to assign positions in political office, and thus to reduce the power of aristocratic families. Hilde de Weerdt examines the rise of the civil service examination, and reassesses its promise of social mobility.

Do restoration techniques and types of weed control influence the composition of edaphic entomofauna?
Authors: Providello Alexandra , Fujihara Ricardo T. , Penha Alessandra S. , Rodrigues Josiane
Published: December 2022

Agroforestry systems (AFS) are generally referred to as systems where perennial plants are associated with annual or perennial crops, spanning from relatively simple agroforestry systems characterized by only two associated species to very complex ones, close to natural systems. However, there are few studies on edaphic entomofauna in newly implanted restoration systems. We investigated the composition of edaphic entomofauna in areas managed under different restoration techniques (agroforestry system or mixed-planting) and types of weed control (chemical or mowing). In each treatment, we performed collections with pitfall traps in July and December 2017. A total of 11,727 specimens distributed in 11 orders and 45 families were collected. Most of the individuals collected were Collembola (53.86%) and Hymenoptera: Formicidae (31.50%). No significant interaction was observed between restoration techniques and types of weed control combined. However, for abundance, both restoration techniques and types of weed control were individually significant, with chemical control showing a higher abundance in relation to mowing, and agroforestry concerning mixed-planting. There was no significant difference in richness in any of the variables studied. We conclude that the agroforestry system and the chemical control can be viable for edaphic entomofauna, although future research is necessary to evaluate the dynamic of edaphic entomofauna during the development of agroforestry systems.

El trabajo ofrece una primera caracterización petrográfica de las pastas de cerámicas San José de comienzos del Período de los Desarrollos Regionales en el valle de Yocavil o Santa María, provincia de Catamarca, Noroeste argentino. La muestra regional analizada está conformada por 30 fragmentos cerámicos recolectados en sitios del centro y sur del valle. El estudio aporta información desde la tecnología para la definición del estilo San José y sus variantes, identificadas a partir de atributos de la forma y diseños. Se describen las pastas cerámicas para conocer aspectos de su producción, en particular se busca observar qué clases de materiales antiplásticos fueron empleados en la elaboración de las pastas, en esta línea nos interesa observar en qué medida las alfarerías San José participaron de la tradición tecnológica del tiesto molido, que se manifiesta a lo largo del Período de los Desarrollos Regionales en diferentes estilos, como las variantes Santa María de la tradición Yocavil. Los resultados iniciales indican que, con excepción de un caso fuera de modalidad, el tiesto molido no es un antiplástico característico en las alfarerías San José.
Recrear el cosmos en la cocina: cocción y comensalidad en el sitio Guitián (Salta, Argentina)
Authors: Amuedo Claudia
Published: December 2022

Es probable que el encuentro entre las poblaciones locales diaguitas y los inkas tuviera puntos de acuerdo y otros disruptivos. Las relaciones entre existentes mediante mecanismos de intercambio y reciprocidad son un ejemplo de estos puntos de acuerdo, mientras que la centralización de dichos mecanismos a partir de la incorporación de los diaguitas al Tawantisuyu representó una novedad y por ende, un punto de conflicto. En este artículo analizaremos, a través del estudio arqueobotánico de un contexto arqueológico de cocina, cómo eran preparados los alimentos en encuentros de comensalidad política entre humanos y no humanos en la plaza de Guitián (Salta, Argentina).

Published: December 2022

Se presentan los primeros resultados de las investigaciones efectuadas en la localidad arqueológica Laguna Giaccone, localizada en el Campo de Dunas del Centro Pampeano (Buenos Aires, Argentina). Los objetivos son evaluar los aspectos tafonómicos que afectaron el conjunto óseo y determinar las especies animales explotadas, identificar las materias primas líticas, su área de procedencia y las tendencias tecnología desarrolladas sobre cada roca y analizar los aspectos tecno-morfológicos relacionados con la manufactura de la cerámica. Entre los procesos y agentes que más afectaron al conjunto faunístico se encuentran el manganeso, los roedores, el pisoteo y la acción de insectos. Se evidencia que el guanaco, el ñandú y un cormorán/biguá fueron procesados por los grupos cazadores-recolectores. Respecto del material lítico, predominan la ortocuarcita y la ftanita de las sierras de Tandilia y se identificó una amplia diversidad de rocas procedentes de otras fuentes de la región pampeana. Están presentes las últimas etapas de las cadenas operativas y una amplia diversidad de instrumentos. Se registró un alto número de vasijas, algunas confeccionadas mediante la técnica de rollo y cocinadas bajo una atmosfera no oxidante. Las morfologías corresponden a contenedores abiertos y algunos tiestos están decorados. Las distintas líneas de evidencia sugieren que parte de las ocupaciones corresponderían a loci de actividades múltiples desarrolladas durante el Holoceno tardío donde se efectuaron diversas tareas vinculadas con el ámbito doméstico, como el procesamiento y consumo de los recursos animales, la manufactura y uso de instrumentos líticos y la preparación de los alimentos en los recipientes cerámicos.
Puntas de proyectil “San Martín” del sitio Cueva Nacimiento 2: implicancias para analizar el proceso de cambio cultural durante el Holoceno medio en la puna de Salta (Argentina)
Authors: Restifo Federico
Published: December 2022

Se analizan las primeras puntas de proyectil San Martín halladas en un contexto con fechado absoluto en la Puna de Salta, correspondiente al sitio Cueva Nacimiento 2, y focalizando en su morfología, secuencia de talla y variabilidad en sistemas de armas. La integración con resultados previos obtenidos en la cuenca de Salinas Grandes (21 ejemplares) muestra variaciones morfológicas dentro del tipo general San Martín; variabilidad en las secuencias de talla; y su posible uso como parte de armas de mano y lanzas arrojadizas. Esto último se sustenta también mediante la comparación con once ejemplares de puntas triangulares apedunculadas asignables al Holoceno temprano. Se plantea que las puntas San Martín representan parte de la diversidad creciente de puntas de proyectil observada desde inicios del Holoceno medio en la Puna de Salta, lo que tendría relación con estrategias de minimización del riesgo en un contexto de cambio ecológico y social.

The article presents the results of treatment of 157 patients with generalized periodontitis depending on blood type. In the blood of patients with generalized periodontitis was determined: the number of erythrocytes, the number of leukocytes, platelets, neutrophils, leukocyte intoxication index, fibrinogen. After treatment, analysis of blood cell composition showed that 1 year after treatment of generalized periodontitis, carriers of 0 (I) and A (II) blood type increased the number of erythrocytes in the blood – 1.2 times. At the same time, a decrease in the number of leukocytes on average was determined by 1.4 times, and leukocyte intoxication index values – by 2.0 times in representatives of 0 (I) and B (III) blood type; neutrophils – 1.4 times in people with A (II) blood type; platelets – 1.3 times in carriers with 0 (I) and AB (IV) blood type, according to data before treatment. The improvement of hematological and hemostasiological indicators of blood in patients with generalized periodontitis indicates a positive effect on the organs and systems the medicines we have prescribed, the positive effect of which is reflected, in particular, on the complex of tooth-retaining tissues.
Responsabilité, crises et globalisation : la sanction du marché
Authors: Bazin Laurent
Published: December 2022

La notion de responsabilité est un terme clé du lexique contemporain sur le développement. Elle est inscrite au cœur des diverses notions qui le composent, en particulier dans l’élaboration de la norme de gouvernance et des politiques mondiales de lutte contre la pauvreté qui ont marqué la première décennie du xxi e  siècle. Cet article s’efforce de montrer que si la responsabilisation semble le mot d’ordre du discours néolibéral actuel, c’est que la responsabilité est l’envers de la domination par les marchés financiers, qui exercent le pouvoir de sanction. La responsabilité est l’opérateur d’un triple transfert de richesses, de risques et de moralité.
Les objets encombrants de la croissance verte et inclusive
Authors: Slim Assen
Published: December 2022

Cet article s’attache à montrer que la croissance verte et inclusive ne remet pas en cause l’accumulation continue et indéfinie du capital. Elle peine de ce fait à répondre efficacement à la crise environnementale qui menace les conditions d’habitabilité humaine de la Terre. Les injonctions réglementaires, morales et normatives associées à la croissance verte sont de ce fait paradoxales. Elles conduisent à l’émergence d’objets encombrants à la croisée d’intérêts contradictoires et dont la résolution temporaire ou définitive appelle quatre stratégies possibles : l’ajournement, le faux compromis, le compromis et le rejet.
Confucianisme et éthique entrepreneuriale : quelques aspects managériaux de l’entreprise « confucéenne » en Chine contemporaine
Authors: Jiang Fu Lan
Published: December 2022

S’inscrivant dans le « renouveau confucéen » apparu au sein de la population chinoise à partir des années 2000, une forte mobilisation des ressources traditionnelles relevant principalement du confucianisme dans les approches managériales s’observe dans le monde des entrepreneurs. Reposant sur une enquête de terrain effectuée entre 2016 et 2019 dans trois entreprises privées chinoises, nous essayons de répondre aux questions suivantes : dans quelles mesures ces entreprises « confucéennes » s’inspirent-elles de valeurs traditionnelles pour la gestion de leurs activités dans le but de fonder une éthique entrepreneuriale ? Quelles sont les particularités et les raisons intrinsèques des mobilisations de ces entrepreneurs ? Nous nous interrogerons également sur une question plus large : comment la tradition constitue-t-elle une ressource importante permettant la moralisation du capitalisme dans la Chine contemporaine ?
Alerte éthique générale : de la grande entreprise au secteur social et médico-social
Authors: Salmon Anne
Published: December 2022

Un discours inattendu s’est déployé dans les entreprises à la fin du xx e  siècle. Au tout début des années 1990, il était difficile d’y déceler une « éthique managériale » soutenue par les acteurs dominant la scène économique. De nos jours, dans le social et le médico-social, force est de constater que de nombreuses structures aspirent à leur tour à restaurer une éthique professionnelle en dissociant cette question de l’emprise gestionnaire qui enserre les pratiques. Cet article entend alerter sur les problèmes que posent ces clivages en examinant les liens entre le néolibéralisme, le nouveau management, l’engouement éthique et ses métamorphoses disciplinaires.
Racisme tacite et fantasme de la blanchité
Authors: Warfield Rawls Anne , Duck Waverly
Published: December 2022

Résumé En proposant de décrire le racisme tacite dans cet article, les auteurs abordent les contextes sociaux conflictuels de l’Amérique noire et de l’Amérique blanche par le biais des attentes tacites en matière d’interaction qu’ils expriment. Ces attentes sont si différentes, voire opposées, qu’elles entravent souvent la communication, le travail de reconnaissance des identités entre les races. Sans la capacité de communiquer et de « voir » l’Autre racialisé dans l’identité et la définition de la situation dans laquelle il se trouve, il ne peut y avoir ni empathie ni compréhension : seulement la peur, la colère, la confusion, la division et la violence.
Extension of aggregation operators to site selection for solid waste management under neutrosophic hypersoft set
Authors: Zulqarnain Rana Muhammad , Ma Wen Xiu , Siddique Imran , Gurmani Shahid Hussain , Jarad Fahd , Ahamad Muhammad Irfan
Published: December 2022

With the fast growth of the economy and rapid urbanization, the waste produced by the urban population also rises as the population increases. Due to communal, ecological, and financial constrictions, indicating a landfill site has become perplexing. Also, the choice of the landfill site is oppressed with vagueness and complexity due to the deficiency of information from experts and the existence of indeterminate data in the decision-making (DM) process. The neutrosophic hypersoft set (NHSS) is the most generalized form of the neutrosophic soft set, which deals with the multi-sub-attributes of the alternatives. The NHSS accurately judges the insufficiencies, concerns, and hesitation in the DM process compared to IFHSS and PFHSS, considering the truthiness, falsity, and indeterminacy of each sub-attribute of given parameters. This research extant the operational laws for neutrosophic hypersoft numbers (NHSNs). Furthermore, we introduce the aggregation operators (AOs) for NHSS, such as neutrosophic hypersoft weighted average (NHSWA) and neutrosophic hypersoft weighted geometric (NHSWG) operators, with their necessary properties. Also, a novel multi-criteria decision-making (MCDM) approach has been developed for site selection of solid waste management (SWM). Moreover, a numerical description is presented to confirm the reliability and usability of the proposed technique. The output of the advocated algorithm is compared with the related models already established to regulate the favorable features of the planned study.
Dynamics and simulations of stochastic COVID-19 epidemic model using Legendre spectral collocation method
Authors: Ali Ishtiaq , Khan Sami Ullah
Published: December 2022

The aim of this study is to investigate the dynamics of epidemic transmission of COVID-19 SEIR stochastic model with generalized saturated incidence rate. We assume that the random perturbations depends on white noises, which implies that it is directly proportional to the steady states. The existence and uniqueness of the positive solution along with the stability analysis is provided under disease-free and endemic equilibrium conditions for asymptotically stable transmission dynamics of the model. An epidemiological metric based on the ratio of basic reproduction is used to describe the transmission of an infectious disease using different parameters values involve in the proposed model. A higher order scheme based on Legendre spectral collocation method is used for the numerical simulations. For the better understanding of the proposed scheme, a comparison is made with the deterministic counterpart. In order to confirm the theoretical analysis, we provide a number of numerical examples.
On Pythagorean fuzzy ideals of a classical ring
Authors: Razaq Abdul , Alhamzi Ghaliah
Published: December 2022

The Pythagorean fuzzy set is an extension of the intuitionistic fuzzy set and is an effective approach of handling uncertain situations. Ring theory is a prominent branch of abstract algebra, vibrant in wide areas of current research in mathematics, computer science and mathematical/theoretical physics. In the theory of rings, the study of ideals is significant in many ways. Keeping in mind the importance of ring theory and Pythagorean fuzzy set, in the present article, we characterize the concept of Pythagorean fuzzy ideals in classical rings and study its numerous algebraic properties. We define the concept of Pythagorean fuzzy cosets of a Pythagorean fuzzy ideal and prove that the set of all Pythagorean fuzzy cosets of a Pythagorean fuzzy ideal forms a ring under certain binary operations. Furthermore, we present Pythagorean fuzzy version of the fundamental theorem of ring homomorphism. We also introduce the concept of Pythagorean fuzzy semi-prime ideals and give a detailed exposition of its different algebraic characteristics. In the end, we characterized regular rings by virtue of Pythagorean fuzzy ideals.
La souverainisation numérique en Russie et son impact sur les militants
Authors: Kossov Valéry
Published: December 2022

Divers acteurs impliqués dans le domaine numérique défendent la « souveraineté » d’Internet en pensant ce dernier comme un espace entier et global où aucune partie prenante ne puisse dominer. Au contraire, les politiques des États réglementant l’espace numérique font apparaître une notion d’Internet souverain qui suppose la fragmentation de cet espace aligné aux frontières nationales. À partir du début des années 2010, plusieurs instances officielles russes, depuis le président de la fédération et le gouvernement jusqu’aux parlementaires, exposent leur vision de la souveraineté numérique qui se présente d’une manière uniforme à travers les documents et discours officiels et s’inscrit dans le cadre du modèle néo-westphalien, qui a pris forme dans la doctrine de la politique internationale russe à la fin des années 1990. Afin de suivre la logique étatique de la souverainisation d’Internet et ses finalités, l’article interroge le lien entre les représentations de la souveraineté numérique dans la doctrine, les discours et le répertoire de moyens juridiques assurant son exercice par les institutions publiques. Enfin, à partir d’entretiens et du suivi de la jurisprudence, cette étude se tourne vers les pratiques d’application des lois en les articulant aux moyens de résistance et d’adaptation des avocats spécialisés en droits numériques et d’autres acteurs militants touchés par les effets répressifs de la législation. Cela permet de dégager quelques perspectives concernant l’impact de la souverainisation d’Internet sur le militantisme en Russie.
Conflit contre un projet de méga-décharge à Shies
Authors: Poupin Perrine
Published: December 2022

Cet article aborde la notion de souveraineté en contexte numérique à partir de l’analyse d’une mobilisation contre un projet d’aménagement dans le nord de la Russie, à la frontière de la région d’Arkhangelsk et de la République des Komis. L’analyse de ce cas montre que la souveraineté, qui n’est pas seulement institutionnelle, mais également citoyenne (ou populaire), est redéfinie au quotidien par différentes initiatives qui engagent des institutions, des entreprises et des citoyens dans la sphère numérique. D’abord, l’article restituera l’histoire de la mobilisation des habitants. Il décrit les actions étatiques par et sur le numérique, parfois par l’intermédiaire de plateformes privées, pour promouvoir le projet d’aménagement illégal, contrôler l’information et réduire au silence les critiques. Ensuite, il aborde le versant « citoyen » de la réalisation de la souveraineté et met en évidence que l’appropriation des technologies numériques donne ainsi lieu à de nouvelles configurations des rapports de force entre pouvoir et société en Russie.
Cuba : un hackerspace à ciel ouvert ?
Authors: Beltrán Natalia Calderón
Published: December 2022

Cet article s’attache à comprendre la politique de souveraineté technologique dans le domaine informatique à Cuba. S’intéresser à la « souveraineté nationale » revient à observer un mouvement de pendule entre des échelles populaire et étatique, sans se restreindre à l’une ou à l’autre, et ainsi, à mettre en évidence ses contours fluctuants. Cette souveraineté là est concurrencée par le haut par divers États et des multinationales et, par le bas, par certaines pratiques populaires. Nous explorons cette tension épistémologique et politique entre une souveraineté populaire et son éventuelle captation étatique. Dans une première partie, nous verrons l’émergence de politiques publiques volontaristes liées au contexte de déconnexion à Internet. Elles ont stimulé un terreau contestataire lié au hacking d’État. Dans une seconde partie, nous exposerons les usages alternatifs populaires tolérés à la lisière de la légalité de ce même État. Elles seront comprises comme des tactiques du quotidien et nous observerons le rôle des activistes dans d’autres modalités de hacking que nous désignerons par le terme de technocontestation, un registre de contestation par la technique.
À la croisée de la science et de la fiction, l’appropriation des tatouages connectés : quelles représentations pour quels usages ?
Authors: Boutet-Diéye Annabelle , Seznec Aurélie
Published: December 2022

Dans une société hyperconnectée, qui questionne le statut du corps, notre article présente les résultats d’un travail de recherche exploratoire mené sur la convergence possible du monde du tatouage et des technologies numériques. À partir d’un état de l’art et d’une méthodologie qualitative basée sur des entretiens semi-directifs, nous avons posé des hypothèses sur de possibles transferts d’appétence entre les deux univers : celui du tatouage et celui des innovations numériques. Selon nous, la digitalisation du tatouage s’inscrit dans une longue tradition où le tatouage répond à des fonctions esthétiques, médicales et thérapeutiques. Ce qui pose la question de la médicalisation de la beauté et de l’esthétisation de la santé. Les pratiques du tatouage et les processus d’appropriation des innovations dans ce domaine seront interrogés. Nous reviendrons sur la place particulière de l’imaginaire et, plus spécifiquement, de la science-fiction pour expliquer les représentations autour du tatouage connecté.

The pandemic caused by COVID-19 triggered several adverse mental health situations in everyone's lives, particularly in health care professionals, especially those on the frontline. It is in this context that the starting question arises: Is COVID-19 enhancing the burnout syndrome in Portuguese public health professionals? This is the main objective of this research, and to this end a quantitative study based on a systematic review of the literature will be conducted to assess changes in burnout levels and to identify predictors of burnout in health care professionals. It was concluded that in the study by Almeida et al. conducted in Portugal, the majority of health care professionals do not have burnout symptoms, only 32.1%; while the factors that imply burnout prevalence were identified as having a medium or low level of resilience (OR=6.8), the perception of lack of social/family support (OR=5.4), and having more concerns about the future post-pandemic (OR=4.5).
Fin-Cology or Tech-Nance?
Authors: Vutharkar Swarnasree , K. V. Rajesh Kumar
Published: December 2022

The words “financial” and “technology” are combined to form the phrase “fintech.” Despite being a wide expression with numerous interpretations, it typically refers to the growth of a sector when new technology use-cases are developed and put into place to expedite more traditional-looking financial activities. When it first arose in the 21st century, the term “fintech” was used to describe the technology employed in the back-end systems of reputable financial organisations. Since then, nevertheless, there has been a shift toward more client-centered services, and thus, a more client-centric definition. Currently, the term “fintech” is used to describe a wide range of professions and businesses, including investment management, retail banking, education, and non-profit fundraising, to name a few. In this chapter you will be reading the relation between python and finance; SQL and finance; Tableau and finance; Power Bi and finance; and Block Chain and finance.
Machine Learning-Based Stock Price Prediction for Business Intelligence

Published: December 2022

The act of digital marketing uses a variety of traditional methods such as analyst consensus, earnings per share estimation, or fundamental intrinsic valuation. Also, social media management, automation, content marketing, and community development are some of the most popular uses for digital marketing. Stock price prediction is a challenging task since there are so many factors to take into account, such as economic conditions, political events, and other environmental elements that might influence the stock price. Due to these considerations, determining the dependency of a single factor on future pricing and patterns is challenging. The authors examine Apple's stock data from Yahoo API and use sentiment categorization to predict its future stock movement and to find the impact of “public sentiment” on “market trends.” The main purpose of this chapter is to predict the rise and fall with high accuracy degrees. The authors use an artificial intelligence-based machine learning model to train, evaluate, and improve the performance of digital marketing strategies.

Published: December 2022

In the era of the fourth industrial revolution, the cyber physical systems, intended as enabling tools to generate an autonomous system, able to facilitate the relationships between different and distant objects and subjects, allow to digitalize the production system, in order to better outline what constitutes the smart factory. The benefit of such systems is the ability to associate to physical objects and virtual or digital models useful information related to the analyzed object, such as life cycle, geometry, mechanical properties, and parameters related to management and maintenance. This contribution aims to evaluate building information modeling methodology in the industrial context, as a cyber-physical system, developing flexible 3D parametric models as a data set, where information can be visualized and optimized management, using different visualization tools. The research has underlined the importance to share information between virtual and real worlds through virtual and augmented reality (VAR) systems.

Building information models (BIMs) make it possible to share structured data in the planning and building process and during the live cycle of the building. The models can be enrichened with information in all stages from planning to end-of-life. Predefined information requirements, data structures, and file formats allow the model to be used for design, cost planning, and time scheduling as well as analysis of building performance, and ideally also for facilities management. This chapter describes the possibilities of using application programming interfaces (APIs) to enhance the usefulness of BIM models. This provides the user with the possibility of creating own applications with real time bidirectional data exchange. Of particular interest is the exchange of data with web-based data sources. The applicability is illustrated with examples of environmental analysis based on web-based data and the use of web-based forms to enrichen BIM models with data input from building users.

Published: December 2022

The world is witnessing an all-level digitalization that guides the industry and business to a restructuration in order to adapt to the new requirements of the surrounding environment. That change also concerns the labour of the technical professionals and their formation. As a consequence of this deep consciousness-raising, this chapter will investigate and develop simulation models based on the current digitalization. The aim of this chapter is the exposition of a real case development of “digital twin” models framed as part of the condition-based maintenance paradigm to improve real-time assets operation and maintenance. This model contributes by providing real-time results that could turn into a basis for the industrial management decisions and place them in the Industry 4.0 paradigm environment.
The Gaming Experience With AI
Authors: Khatri Preety
Published: December 2022

There are several uses of artificial intelligence in games that are useful for the better game design. With the help of AI, we can improve the games in different ways by simply playing them. In the game industry, when artificial intelligence of the game enhances to the profitable value of the game, this adds to better game reviews, which results to improve the experience of the player. By using AI, we can control both the player as well as non-player characters of the game. AI emphasizes on optimizing the performance of play, which means to measure the degree to which a player comes across the goals of the game, in case of player character. Whereas the role of AI in case of a non-player character emphasizes automatic game balancing mechanisms as well as allow dynamic difficulty adjustment. The use of AI for the empathetic player experience can improve and drive the design process of games. This chapter explores gaming with AI.
Augmented Reality Games
Authors: Atiker Baris
Published: December 2022

Augmented reality strengthens its ties with the gaming world every day. The fact that smartphones can be used as an augmented reality tool, in particular, shows this interest as a remarkable phenomenon for both gamers and game producers. The development of augmented reality applications is of great importance for the future of the gaming world, as it is not only limited to mobile phones but also covers more sophisticated devices. This research intends to evaluate how augmented reality games interpret gaming concepts and principles, through field research methods, new applications, and studies that deal with gamification, presence, immersion, and game transfer phenomena. It is also aimed to make inferences about how our daily life can be gamified in the near future thanks to augmented reality.
Codebook Co-Development to Understand Fidelity and Initiate Artificial Intelligence in Serious Games
Authors: Ravyse Werner Siegfried , Blignaut A. Seugnet , Botha-Ravyse Chrisna R.
Published: December 2022

This study aimed to identify and rank the serious game fidelity themes that should be considered for retaining both the learning potential and predicted market growth of serious games. The authors also investigated existing links between fidelity and AI. The methodology unraveled serious game fidelity through the co-development of a theory- and data-driven codebook, applying the constant comparison method for data analysis. The theory-driven codes stemmed from literature while the data-driven codes emerged from a heuristic user interface evaluation of a comic book style game, named ExMan. This article identifies five fidelity themes, with functional fidelity as most important, and postulates that functional fidelity is most suited to AI integration. This study delivers a fidelity-for-serious-games codebook and concludes that observing the suggested fidelity hierarchy could safeguard that neither digital game-based learning is watered down, nor the lustre of digital gameplay dulled. Furthermore, the authors hold that AI for serious games should be given a high design priority.
Identifying Latent Semantics in Action Games for Player Modeling
Authors: Kermanidis Katia Lida
Published: December 2022

Machine learning approaches to player modeling traditionally employ a high-level game-knowledge-based feature for representing game sessions, and often player behavioral features as well. The present work makes use of generic low-level features and latent semantic analysis for unsupervised player modeling, but mostly for revealing underlying hidden information regarding game semantics that is not easily detectable beforehand.
Multi-Disciplinary Paths to Actor-Centric Non-Player Character Emotion Models
Authors: Schiffer Sheldon
Published: December 2022

Video game non-player characters (NPCs) are a type of agent that often inherits emotion models and functions from ancestor virtual agents. Few emotion models have been designed for NPCs explicitly, and therefore do not approach the expressive possibilities available to live-action performing actors nor hand-crafted animated characters. With distinct perspectives on emotion generation from multiple fields within narratology and computational cognitive psychology, the architecture of NPC emotion systems can reflect the theories and practices of performing artists. This chapter argues that the deployment of virtual agent emotion models applied to NPCs can constrain the performative aesthetic properties of NPCs. An actor-centric emotion model can accommodate creative processes for actors and may reveal what features emotion model architectures should have that are most useful for contemporary game production of photorealistic NPCs that achieve cinematic acting styles and robust narrative design.
Emotional Agents in Educational Game Design
Authors: Gutica Mirela , Petrina Stephen
Published: December 2022

Evaluating the subjective playing experience and engagement in learning is important in the design of advanced learning technologies (ALTs) that respond to the learners' cognitive and emotional states. This article addresses students' attitudes toward an educational game, Heroes of Math Island, and their responses to the emotional agent, an animated monkey. Fifteen students (seven boys and eight girls) from grades six and seven participated in this quasi-experimental study (pretest, intervention, post-test, followed by post-questionnaire and interview). This research presents a detailed analysis of students' subjective reactions with respect to Heroes of Math Island and to the underlying mathematics content, their learning gains and emotions triggered during gameplay, and design issues resulting from the evaluation of the game and of its emotional agent. The findings from this study inform how ALTs and educational games can be designed in order to be effective and provide emotional engagement, enjoyment, and learning.
Designing a Minecraft Simulation Game for Learning a Language Through Knowledge Co-Construction
Authors: Baek Joeun , Park Hyekyeong , Min Ellen
Published: December 2022

The purpose of this chapter is to design a Minecraft simulation game where players can learn a language by communicating and negotiating meaning with other players. To achieve this, Gagné's events of instruction and Schmitt's strategic experience modules were adopted as a theoretical lens for simulation building. After the simulation game was designed, it was implemented to test its feasibility. The result shows that the simulation game has both the intended features of knowledge co-construction and the negotiation of meaning, as well as enjoyment of the game. The test result, however, also suggests that the simulation game needs more conditionals and loops in order for players to repeat their simulation game at any place and time.
