From Being Deprived to Bestowing Privileges – Artistic Reflections of the Wrestlers /Mutri/ Subculture in The Novels by Georgi Stoev
Authors: Debruyne Nina
Published: June 2023

One of the most characteristic phenomena of the Transition in Bulgaria in the 1990s were the socalled Wrestlers’ brigades. Their emergence and rise left a lasting imprint on the social fabric and provided the initial impetus for the formation of the so-called ‘Wrestlers/ Mutri’ subculture. In a situation of rapidly changing public, economic and social environments in Bulgaria after the fall of the totalitarian regime in 1989, the Wrestlers’ brigades gave young men with modest family backgrounds the opportunity to become part of a set enjoying a progressively privileged economic and social circumstance. In the aftermath of the state's abdication of its regulatory and adjudicative functions, these groups and their individual members gained access to various power levers and transformed from privileged to privileging — granting privileges — both to in-group members (family, friends, etc.) and outsiders such as politicians, business people, artists, etc. This process of transformation from disadvantaged to privileged in this context has not yet been fully explored. The available documentary and archival information is currently limited and difficult to access. Fiction as a parallel source allows us to consider these processes from a different angle. The purpose of the proposed paper is to analyse the novels of Georgi Stoev – admittedly a former member of a Wrestler’s group, as a source of information about the process of transformation from disadvantage to privilege and of specific subcultural traits. By comparing the information in the eight books in the ‘Witnesses of the Times’ and ‘BG Godfather’ series with publicly available documents, studies and publications, a deeper understanding is obtained of the values and dynamics of the Wrestlers/ Mutri subculture in Bulgaria at the end of the 20th and the beginning of the 21st century.
The Czech Verb Tunelovat and Its Derivatives – a Symbol of Economic Crime Since the 1990s in Czechia
Authors: Krejčí Pavel
Published: June 2023

The change in social and political conditions in Czechoslovakia and then in inde-pendent Czechia after 1989 caused significant dynamics in the creation of new words and expressions or the expansion of the meaning of already existing words. A symbolic representative of the emergence of new words and meanings is the verb tunelovat and its derivatives (tunelování, tunelář, etc.), which began to be used to describe a certain way of realizing economic crime, through which privileged individuals from the time of the communist totalitarian regime become a privileged layer of society and in the new conditions of freedom thanks to their connections, financial security from the past and their entrepreneurial cynicism. The article presents a linguistic analysis of this expression and its derivatives from the point of view of lexical semantics, word for-mation and frequency of use. The analysis is based on both the relevant scientific lit-erature and data from the Czech National Corpus.
The Caucasus in the 1920s – 1930s: the First Clash of the Democratic World with Russian Bolshevism and Its Consequences
Authors: Gotsiridze George
Published: June 2023

The paper analyzes the historical processes taking place in the Caucasus in the 1920s-1930s, which reflect the destruction of the democratic states of the Caucasus by Rus-sian Bolshevism and the efforts of the political elite of the Caucasus to restore the independence through the unification of the Caucasus. The work highlights the actors of these dramatic events and shows the influence of domestic and foreign factors on the mentioned processes. It is emphasized that the first confrontation between Russian Bolshevism and Western-type democracy took place in the Caucasus, which ended with the defeat of the latter. Based on the critical analysis of rich primary sources, emigrant press, and the records of eyewitnesses, the paper explains the reasons for the victory of Russian Bol-shevism, on the one hand, and, of the defeat of the independent democratic states of the Caucasus, on the other hand, the importance of the unification of the Caucasus to achieve common Caucasian goals is highlighted, the indifferent attitude of the West-ern states (with some exceptions) to the ongoing processes in the Caucasus and their negative role in the victory of Russian Bolshevism is shown. It is emphasized that the pursuit of a pragmatic policy, devoid of values, which was carried out by the Western World in relation to Bolshevik Russia/Soviet Union, is disastrous even for pragmatists, that collaboration with totalitarian and autocratic regimes threatens the democracy and world order based on the basic principles of the international law. Based on the reconciliation of historical events, the paper draws parallels between the political processes going on in the period under investigation and the modern world, it is demonstrated the psycho type of Russia, which does not change historically, on one hand, and the mistakes of the Western world, which contribute to its militarization, on the other hand.
Branded Identities. Remarks on the Holocaust chapter of the Macedonian-Bulgarian War on Identity
Authors: Krasztev Péter
Published: June 2023

The paper approaches the issue of the Holocaust in South-Eastern Europe from the perspective of country branding and „competing identities” – term coined by Simon Anholt in the first decade of the 21st century. Though examination of the official North Macedonian and Bulgarian discourses about the WWII reflected in the contem-porary films, serials, political and historical statements, quasi-academic pamphlets, and partly architecture, the study aims to explore the mechanisms of construction of a new, “Holocaust-based” historical identity in these countries. The study argues that the current politics of memory of the two sides is propagandistic and mostly based on PR technologies which are rather indifferent or only partly sensitive to the historical facts and moral/humanist aspects of the question. The conclusion therefore is that the construction of a "competitive identity" by both sides was doomed to failure because countries that cannot achieve a minimum internal consensus on basic human, legal, aesthetic, political, etc. norms and values – as Anholt's concept would require -, have no chance of presenting an outwardly attractive, or at least acceptable, image.
Privileges and „Patronage“ instead of Social Care: "Fighters Against Fascism" in the Social Policies in Communist Bulgaria, 1944–1951
Authors: Angelova Milena
Published: June 2023

This article analyses the formation and institutionalisation of the system of privileges in communist Bulgaria. Right after September 1944, the establishment of a system of privileges was initiated, a system that created special categories of citizens opposed in this way to the rest of society. From 1944 on, former partisans became part of the rul-ing elite and granted themselves and their relatives many privileges, transforming themselves into a specially privileged caste. The analysis is based on the archive doc-uments of the Union of the People’s Guerrilla Fighters and the Union of the Fighters against Fascism – institutions existing in the period 1945–1951. The activities of the ‘fighters’ were aimed at substituting in very short terms after the take over the vectors of the public memory in order to legitimize the new power resources. The social system of total control and caste privileges discredited the idea of modern society, social freedom and equality. The author analyses both legislation as well as the ways in which privileges were constructed in social policies in communist Bulgaria.
The Privileges of Bulgarian Writers at Bulgarian Resorts during the Second Half of the 20th Century: Literary Interpretations and Contextualizations
Authors: Azmanova-Rudarska Elena
Published: June 2023

The article examines the formation of the special resort as a topos in which the pro-cesses of construction and functioning of literary texts were activated in the time of social realism, when privileges and benefits were created for special category of writ-ers. The process began with the formation of the Union of Fighters Against Fascism and Capitalism and grew with the special writers' awards given out on various occa-sions. The preferential use of recreational areas in Bulgaria also creates a kind of zoning - Borovets, Sozopol, Hisarya (Villa "Petrovich"), Varna, "Golden Sands" and others are assigned to Union of the Bulgarian Writers. In this context, literary collec-tions of short stories, novels, literary legends, etc. are compiled. The main thesis of the research is that resort-themed works combine ideology and literature while seemingly maintaining their tolerance for dominant socio-ideology. At the same time, they form a layer of relative freedom and are a peculiar escape from the cruel reality of the totali-tarian state. For the purpose of the report, the normative base (laws, rules, regula-tions, etc.) for the period 1944-1965, as well as memories, letters, journalistic materi-als, archives, works of fiction, are studied.
Psychological Costs and Administrative Burdens Produce Systemic Service Avoidance among People Experiencing Homelessness
Authors: Hoang Tiffany , Felner Jennifer K. , Flanigan Shawn T. , Carroll Megan Welsh
Published: June 2023

How do people experiencing homelessness make decisions about accepting or avoiding social services and health care? The study presented here seeks to answer this question by drawing on remotely-gathered surveys (n=244) and in-depth interviews (n=57) with unhoused people during the first wave of the COVID-19 pandemic. In this paper, we explore service-seeking behaviors and processes to understand how to best support people experiencing homelessness during current and future public health disasters. We find that homelessness services systems are often fragmented, increasing administrative burdens such as learning costs (Herd & Moynihan 2018, 2020) and driving unhoused people away from seeking the support they actually need. Four organizing themes centered on temporary housing, health care and medical racism, precarious employment, and self-preservation became apparent within the broader systems challenges. Findings provide insight into the survival strategies of people experiencing homelessness, including how and why people avoid services. Findings point to systems-level recommendations for better aligning homelessness-serving systems with the actual needs of unhoused people themselves. Lastly, the research approach described here offers lessons learned regarding doing social science research with people experiencing homelessness during public health disasters.
AN ECOCRITICAL APPROACH TO SELECT NATURE POEMS OF EMILY DICKINSON
Authors: Chahal Paramveer
Published: June 2023

The present paper attempts to explore the ecocritical connotations of the selected poems of Emily Dickinson, a prominent nineteenth century American poetess. Nature is one of the most favorite subjects of Dickinson. More than 100 poems based on the same put the stamp upon it. The love for nature made her produce poetry which is no less than that of romantics. Although ecocriticism developed as a literary field in the late twentieth century, the world of nature had already begun to go through deterioration way before that. The Industrial revolution of the nineteenth century can be called the major cause behind the deterioration of the natural world. The poetry of Dickinson raises the awareness among the readers about safeguarding the natural world by depicting the harmony between nature and human beings coupled with the awe for nature. The paper attempts to explore the ecological consciousness that lies in the nature poems of Dickinson. The poetry embodies the harmony between nature and human beings. The aim of the paper is to evoke the ecological consciousness within people in order to appreciate the beauty of nature and protect the environment.

GRB 191019A: A Short Gamma-Ray Burst in Disguise from the Disk of an Active Galactic Nucleus
Authors: Lazzati Davide , Perna Rosalba , Gompertz Benjamin P. , Levan Andrew J.
Published: June 2023

Long and short gamma-ray bursts (GRBs), canonically separated at around 2 s duration, are associated with different progenitors: the collapse of a massive star and the merger of two compact objects, respectively. GRB 191019A was a long GRB (T
90 ∼ 64 s). Despite the relatively small redshift z = 0.248 and Hubble Space Telescope follow-up observations, an accompanying supernova was not detected. In addition, the host galaxy did not have significant star formation activity. Here we propose that GRB 191019A was produced by a binary compact merger, whose prompt emission was stretched in time by the interaction with a dense external medium. This would be expected if the burst progenitor was located in the disk of an active galactic nucleus, as supported by the burst localization close to the center of its host galaxy. We show that the light curve of GRB 191019A can be well modeled by a burst of intrinsic duration t
eng = 1.1 s and of energy E
iso = 1051 erg seen moderately off axis, exploding in a medium of density ∼107–108 cm−3. The double-peaked light curve carries the telltale features predicted for GRBs in high-density media, where the first peak is produced by the photosphere and the second by the overlap of reverse shocks that take place before the internal shocks could happen. This would make GRB 191019A the first confirmed stellar explosion from within an accretion disk, with important implications for the formation and evolution of stars in accretion flows and for gravitational-waves source populations.
Observation of a Lunar Eclipse at 89, 150, and 183 GHz
Authors: Burgdorf Martin J. , Liu Niutao , Buehler Stefan A. , Jin Ya-Qiu
Published: June 2023

We describe the measurement of the brightness temperature of the Moon from space during a total lunar eclipse by using a microwave sounder aboard a weather satellite. Previous observations of lunar eclipses were inconsistent and did not cover the frequency range between 100 and 200 GHz. In this work, we seek to establish a reliable relationship between frequency and drop in brightness temperature during a total eclipse for millimeter wavelengths. For this purpose, we chose the eclipse on 2004 October 28, because it coincided with appearances of the Moon in the deep space view of the Advanced Microwave Sounding Unit-B on NOAA-15. It was therefore possible to measure its disk-integrated radiance at 89, 150, and 183 GHz at 100 minutes intervals. Our observations are, to the best of our knowledge, the only ones between 100 and 200 GHz, and demonstrate the nearly linear dependency on frequency of the maximum relative drop in effective temperature during an eclipse. The slope of this function is m = 0.00114 ± 0.00017 GHz−1 in the range 88–300 GHz. The good agreement between the variations of the effective lunar temperature and a new radiative-transfer model suggests that the Moon is suitable as a flux standard for microwave observations with beam sizes larger than 0.5°.

Dear Readers, 

It gives me great pleasure to announce the sixth regular issue of 2023. In this issue, 5 papers cover various topical aspects of computer science by 16 authors from 4 countries. In an ongoing effort to further strengthen our journal, I would like to expand the editorial board: If you are a tenured associate professor or above with a strong publication record, you are welcome to apply to join our editorial board. We are also interested in high-quality proposals for special issues on new topics and trends. 

As always, I would like to thank all authors for their sound research and the editorial board and our guest reviewers for their extremely valuable review effort and suggestions for improvement. These contributions, together with the generous support of the consortium members, sustain the quality of our journal. 

In this regular issue, I am very pleased to introduce the following 5 accepted articles: In a collaborative research effort between Morocco and Spain, Soukaina Benabdelouahab, José A. García-Berná, Chaimae Moumouh, Juan M. Carrillo-de-Gea, Jaber El Bouhdidi, Yacine El Younoussi, and José L. Fernández-Alemán report on their bibliometric study on e-learning software engineering education by conducting an analysis of 10,603 publications, dating from 1954 to 2020. Achraf Boumhidi, Abdessamad Benlahbib and El Habib Nfaoui from Morocco propose in their research a financially-oriented reputation system that generates a single numerical value from user-generated content on Twitter toward cryptocurrencies by applying a sentiment polarity extractor based on the fine-tuned auto-regressive language model named XLNet. Samuel Caetano da Silva and Ivandré Paraboni from Brazil focus on politically-oriented information inference from text by a series of experiments to compare a number of strategies for political bias and ideology inference from text data using sequence-based BERT models, syntax- and semantics-driven features. Burak Gülmez from Türkiye discusses a model developed for disease detection from images of cotton leaves applying a deep convolutional neural network model and the grey wolf optimization algorithm. This model outperforms the ResNet50, VGG19, and InceptionV3 models frequently used in the literature. Last but not least, José L. López Ruiz, Ángeles Verdejo Espinosa and Macarena Espinilla Estévez from Spain discuss a new methodology for the optimization of Bluetooth anchors for location-relevant systems in an enclosed space using a machine learning-based inference model based on different configurations of the BLE anchors located in the enclosed environment.

Godparenthood in the Context of Family Relations in the 19th Century Bohemian Rural Space
Authors: Skorepová Markéta
Published: June 2023

L’article s’intéresse à la problématique des liens de parrainage dans le milieu rural tchèque, à partir de l’exemple de la paroisse de Nový Rychnov. L’analyse s’appuie sur une base de données de 7 229 enfants nés dans la région étudiée au cours des années 1800-1899. L’étude du parrainage est utilisée comme un outil pour explorer les rapports sociaux et les changements de mentalité de la société rurale à l’époque de la modernisation. Un parrain et une marraine se présentaient habituellement aux baptêmes; ce n’est que dans la dernière décennie du xix e siècle que sont apparus les baptêmes avec un parrain unique. Les couples de parrain et marraine étaient d’habitude formés par des personnes en lien de parenté proche, le plus souvent des époux. L’observation du choix des parrains au sein des différentes familles a montré un parrainage se répétant régulièrement dans le cas des frères et sœurs. Un tiers des enfants environ étaient apparentés biologiquement avec au moins l’un des parrain et marraine, la tendance à une familialisation du parrainage devenant plus forte dans le courant du xix e siècle. Parmi les parrains (hommes) apparentés biologiquement, on voit apparaître une prédominance des parents matrilinéaires, le lien de parenté avec les marraines n’était pas si important. Le parrainage par des parents avait un rôle socialisant majeur dans le cas des enfants nés hors mariage.
Business with a mission: Introducing sustainability entrepreneurship
Authors: Sheldon Robert Charles , Lüdeke-Freund Florian
Published: June 2023

Cet article traite de la notion d’entrepreneuriat au service de la durabilité par opposition aux conceptions actuelles autour de la fusion de l’entrepreneuriat et de la durabilité, en particulier l’entrepreneuriat durable, l’entrepreneuriat écologique et l’entrepreneuriat social. Il commence par définir le terme et mettre en évidence ses caractéristiques distinctives. Il approfondit ensuite la notion de développement durable, une construction de niveau macro, montrant comment elle se rapporte logiquement à l’entreprise, une construction de niveau méso. Cette analyse permet de voir les différences saillantes entre les diverses applications de l’entrepreneuriat dans les domaines sociaux et environnementaux. En fin de compte, trois facteurs distinguent l’entrepreneuriat au service de la durabilité. Le premier est la mission de durabilité comme principe fondateur, le deuxième est l’inclusion possible dans la mission de ressources dites sociétales, et le troisième correspond aux moyens par lesquels cette mission est réalisée, à savoir les leviers de durabilité et une relation positive entre les revenus et l’impact. L’article se termine par une discussion sur les mesures, ou les moyens par lesquels les entrepreneurs suivent l’impact qu’ils ont dans l’espace de la mission.

La gouvernance du Mobility as a Service (MaaS) : quelle approche de gouvernance favorisent les autorités publiques dans le développement de MaaS ?
Authors: JANKE Julia
Published: June 2023

Cet article vise à mettre en lumière le rôle des autorités publiques et leurs approches de gouvernance dans le développement de MaaS (Mobility as a Service) – des plateformes multimodales facilitant les déplacements. Une revue des publications permet de distinguer quatre approches de gouvernance de la part des autorités publiques : la gouvernance par l’autorité, par la facilitation, par l’action et par laisser-faire . Les résultats révèlent que l’approche de gouvernance adoptée par les autorités publiques dépend du contexte réglementaire qui définit leurs compétences et leur marge de manœuvre. L’implication des autorités publiques dans le développement du MaaS varie entre échelles administratives ainsi qu’entre pays. La revente des tickets de transports en commun, la sélection des services de mobilité inclus dans un MaaS ainsi que la couverture géographique soulèvent des divergences entre les différents acteurs et remettent en cause les objectifs prometteurs associés à la diffusion de l’outil MaaS.
Intelligence Artificielle et mobilité en Afrique subsaharienne : contribution à l’analyse des applications du domaine des transports et de la logistique
Authors: KIYINDOU Alain , CAPO-CHICHI Gilbert , AMESSINOU Kossi
Published: June 2023

La mobilité est un élément essentiel de l’épanouissement de l’humain et du développement d’un pays. L’Afrique, dont la population est très jeune et donc encline à plus de mobilité, se caractérise par une faible infrastructure routière, ferroviaire, fluviale et aérienne. L’intelligence artificielle est envisagée dans ce travail non comme une solution miracle, mais comme un nouveau champ d’investigation susceptible d’avoir un impact significatif sur la mobilité en Afrique. C’est en cela qu’il est intéressant de voir comment des développeurs informatiques se saisissent de cette technologie pour tenter de résoudre les problèmes liés au transport et à la mobilité en général. Nous avons fait appel au concept de mobilité intelligente dans un contexte marqué par la mise en place de solutions technologiques simples et efficaces sans manquer d’apprécier les concours de l’environnement technologique et socioéconomique de développement de l’intelligence artificielle en Afrique. La boucle de rétroaction des défis locaux observés révèle la complexité de l’acclimatation des inventions qui deviennent des innovations en Afrique. Une enquête de terrain permet de voir l’ingéniosité embarquée par les applications de mobilité en cours d’usage. Elle soulève l’impératif de la maîtrise de l’analyse et de la gestion des données massives et ouvertes dans un environnement en manque de capacités de stockage des données à manipuler à l’ère de l’intelligence artificielle.
L’Auberge espagnole à la maison ou la médiation numérique au service de la mobilité internationale étudiante
Authors: BRASSIER-RODRIGUES Cécilia
Published: June 2023

Dans cet article, nous examinons la manière dont les technologies numériques de l’information et de la communication accompagnent une transformation durable de la mobilité internationale étudiante, dans un contexte sanitaire qui a obligé à repenser les séjours à l’étranger encadrés. Nous verrons que ces outils offrent une formidable opportunité de rompre avec l’immobilité dont sont victimes certains étudiants qui ne peuvent pas partir en mobilité à l’étranger. Nous expliquerons comment les dispositifs numériques relevant de l’internationalisation à la maison permettent d’augmenter le capital de mobilité de tous les étudiants. Ce faisant, nous plaidons en faveur d’une hybridation des mobilités physiques et virtuelles, que l’étudiant pourra valoriser dans un parcours mobilitaire, dont nous proposons une définition. Un nouvel habitus mobilitaire est ainsi en devenir.

Comment mettre les patrimoines culturels rendus temporairement ou définitivement inaccessibles à disposition des publics immobilisés ou distants, pour répondre à leur demande de culture ? Les technologies de l’information et de la communication offrent des réponses instrumentées à ce nouveau défi. Ce type de ressource promeut les mobilités informationnelles en substitution aux mobilités réelles.Après une première partie consacrée à l’introduction du concept de mobilité informationnelle et une revue rapide des solutions existantes, la suite de l’article envisage des dispositifs qui dépassent la simple transposition d’une accessibilité physique empêchée. C’est le cas de la survivance de certains patrimoines, notamment immatériels, au-delà de la disparition de leurs témoins, lorsque la rencontre physique est devenue impossible pour cause de décès.La deuxième partie de l’article traite ainsi du cas du témoignage historique, et l’illustre à travers le dispositif holographique mis en œuvre aux États-Unis pour les témoins de la Shoah. Ce dispositif a été transposé au témoignage des survivants de la mine dans le cadre de l’ANR MémoMines qui fait l’objet de la troisième partie. Ce dernier contexte a permis une étude expérimentale auprès des publics. Dépassant la simple réponse technique à la question initiale, cette étude exploratoire donne des pistes sur la façon dont l’expérience de mobilité informationnelle temporelle est vécue, appréciée par les publics.

Published: June 2023

The purpose of this chapter is to investigate the architecture graduate's viewpoint on their 21st century skills. The study used a quantitative approach. Data was collected using a structured questionnaire from the graduates. A total of 141 graduates completed the online survey measuring the graduates' 21st century skills. The collected data was analyzed using SPSS v 25. The results indicate that development of the 21st century skills among graduates is generally at a moderate level, particularly information, media, and technology skills, and life and career skills. Graduates rated their learning and innovation skills as highest (M=3.76), followed by moderate scores for both life and career skills (M=3.60) and information, media, and technology skills (M= 3.04). This study contributes to the existing literature on 21st century skills by providing students perspective on the subject, which is, thus far, less discussed in existing published research.
Empowering Underrepresented Students
Authors: Caruso Beth
Published: June 2023

Higher education presents students with many opportunities for educational advancement, but not all encounter these opportunities equally. Academic organizations, rooted in structural racism, perpetuate cycles of perceived failure that can prevent students from receiving the encouragement they need, which can result in inadequate career and societal preparation. Not all students benefit from traditional education in the same ways, and when they must all meet the same criteria, then, it is difficult for some to meet their own learning needs and goals based on their own definitions of success. Innovation spaces, such as makerspaces, within academic libraries, have a particular ability to help level the playing field and add equity value to both the classroom and lifelong learning. This chapter delineates current equity issues and provides managers of innovation spaces, especially those in academic libraries, with methods for recognizing opportunities for developing and marketing spaces and services to promote success for every student, both within the classroom and outside of it.

In general, buildings can be classified into Engineering buildings and Non-engineering buildings. Non-engineering building is a simple building such as a residential house that does not carry out structural calculations. Non-engineering buildings are very susceptible to lateral loads such as earthquakes which can cause collapse. Therefore, research is carried out in the form of laboratory tests and numerical tests for reinforced concrete frames filled with prefabricated cellular lightweight concrete (CLC). In this study, two specimens were used, namely an empty frame and a reinforced concrete frame filled with prefabricated CLC. In the laboratory test, it was analyzed by means of a cyclic load test, while in the numerical test the first specimen was made an open frame model and the second infill wall was made as an equivalent diagonal strut. Both of these models were analyzed using the SAP 2000 application version 22 by applying pushovers. The results showed that there were differences in laboratory tests and numerical tests. Therefore, a correction value for the numerical test results is needed to approach the value of the numerical test results.

Airworthiness of Rotorcraft products is established through the certification activity that can be seen as a demonstration process based on rules given in the Certification Specifications and associated Acceptable Means of Compliance. After a presentation of our goals, a delimitation of the field of interest, including certification specifications and acceptable means of compliance and its semantic analysis in the form of taxa, networks and discriminants, we introduce the concepts of rotorcraft breakdown structures, configuration parameters and skill areas forming the underlying ontology behind the certification specifications. Then, we present a parameterized model of rotorcraft breakdown structure in the form of an inference engine. The paper shows how this inference engine can support system designers taking into account, at the right times, the applicable certification requirements and the procedures and standards, acceptable by the authorities for the demonstrations of compliance they have to establish and how it can support certification engineers preparing a certification program and verifying compliance demonstrations performed by system designers. Before concluding and presenting foreseen future works, we present a simple use case intended to illustrate our work.
Systems Engineering – The Art Of Requirements
Authors:   Columbia Helicopters, Pelletier Brad
Published: June 2023

There is an art in requirements that will lead to a product that is completed on budget, on schedule and certified by the FAA. The particular way that requirements are determined, the way that they are worded, the way they are put down on the page all blend to give you the picture of the final product to be developed. The beauty in the process of requirements development is the versatility that the world of requirements has on the vertical flight industry. Requirements are used for manufacturers of small simple products to manufacturers of extremely high complex systems, to include simple or complex software definition, like Artificial Inelegance (AI). Requirements can be documented in multiple ways to include Word, Excel, Dynamic Object Oriented Requirements System (DOORS), or more modern ways like Model Based Systems Engineering (MBSE). This paper is a brief overview of the need for requirements, where requirements fit into the product design lifecycle, and how to develop requirements. The paper will conclude with a brief explanation of how to word good requirements that are verifiable or can be properly validated.

The main objective of this study is to improve maintenance activities using mixed reality. Co-design work with Support Engineers was undertaken to develop a mixed reality solution that corresponded to the different needs of task sequencing feasibility. Multiple versions of the solution were tested using Microsoft HoloLens hardware to achieve continuous improvement. The study compared the two latest versions of the solution: the CAD version and the PHYS version. The CAD version was an immersive version inspired by CATIA CAD software, while the PHYS version implemented a realistic approach to parts handling (including gravity, continuous presence, and spatial organization of physical parts on a real table). Support Engineers carried out an experiment, performing a disassembly/assembly task using both versions of the solution. Results showed that the overall workload was significantly reduced, along with task completion time, using the PHYS solution. The PHYS version was also judged to be more usable than the CAD version. Adding 'pseudo-natural' manipulation of virtual objects to a maintenance task simulation better suits the needs of Support Engineers.
Towards A Regulation Based Functional Hazard Assessment for Safety & Certification Requirements of Hydrogen-Hybrid eVTOLs
Authors:   Technical University of Munich, Bosch Colin , Bertsch Lukas , Yavrucuk Ilkay
Published: June 2023

The multitude of new eVTOL projects provides not only revolutionary configurations, but also the chance to consider cleaner energy sources for providing power. At the same time, regulations for these systems have not been defined in detail. Nevertheless, the use of classical safety assessment standards could assist in preliminary safety and reliability investigations. This work describes an approach to be used to facilitate the creation of functional safety requirements for hydrogen-hybrid architectures for eVTOLs. In a first step, we present an overview of current EU safety regulations to introduce the accepted Target Level of Safety (TLS) which is then followed by a systematic method to describe how a Functional Hazard Assessment (FHA) can be tailored for both manned and unmanned use cases. We apply this process to the power systems of two different VTOL case studies (manned VTOL and UAV), discuss examples of the created FHAs and comment on the shortcomings and benefits of this method.
A Framework to Enhance the Mitigation of Loss of Tail Rotor Effectiveness

Published: June 2023

Loss of tail rotor effectiveness (LTE), also known as unanticipated yaw, has been recognized as a major contributing factor in several helicopter accidents where directional control is lost. Through the Helicopter Flight Data Monitoring (HFDM) program, pilots receive constant flight evaluation reports to support LTE risk mitigation. Nevertheless, the existing LTE safety metric presents several pitfalls that hinder the reliability of the detection of violations of boundaries for flight safety. This paper presents a new framework in the development and evaluation of an expanded safety metric to enhance the detection of proximity to LTE within the HFDM program. The new metric combines three different underlying phenomena that can lead to an LTE event, i.e., loss of weathercock stability, running out of pedal (tail rotor collective) for trim, and tail rotor vortex ring state. A parametric surrogate model for the detection of proximity to an LTE event is formulated by combining results from physics-based simulations with machine learning techniques. The new framework allows for operator fine-tuning of proximity to LTE boundaries, and hence, it provides flexibility in risk management from post-flight analyses. Finally, the framework is compared against the method currently used within the HFDM program, confirming its enhanced detection of the proximity to LTE.
External Airframe Loads Development for Full-Scale Helicopter Fatigue Test Application
Authors:   Mercer Engineering Research Center, Brenna Jeffery , McGinty Dr.
Published: June 2023

This paper presents the development and evaluation of helicopter airframe loads for application to a full-scale fatigue test demonstration. The loads development method utilizes flight strain survey data and an airframe-representative finite element model to relate structural loading to strains. A previously developed approach has been modified to meet the requirements to simulate structural loading from flight conditions on a fixed load frame. A comparative stress-life fatigue analysis using measured flight data and predicted spectra to quantify fatigue prediction accuracy is also presented. A theoretical evaluation found a 10% error in strain prediction could result in up to 74% error in fatigue damage prediction. The practical evaluation using the predicted stress spectra found a wide spread of prediction accuracy. 77% of all predictions are under-predicted, typically in regions of low measured strain. The best predictions, in regions of highest measured strains, were within measurements by a factor of 1.5. These predictions exceed expectations, well within an acceptable level of error, however universal correlation in fatigue prediction is desired.

Published: June 2023

Technology gaps exist for design and certification of bonded repair of large composite structures under multiaxial loading. They are 1) consideration of delamination failure without including the matrix cracking-induced stress concentration at a ply interface; 2) use of test data from a simple geometry for the failure prediction of a complex repaired configuration with a multiaxial stress state and spatial variation of the local stress ratio; 3) pre-assumed failure modes without including the multiaxial stress state-driven damage initiation and progression; and 4) lack of a rational modeling approach for the damage evaluation of a full-scale structure to balance the computational efficiency and solution accuracy. Our primary goal of this study is to extend our modeling capability for a bonded composite structure subjected to multiaxial loading and to demonstrate a global-local modeling capability for the high-fidelity damage evaluation at a critical location of a full-scale composite wing section. Multiaxial tests for a scarf repaired component are performed via the bi-axial cruciform apparatus while a capability demonstration is conducted using the strain survey test of a full-scale wing section via the developed test rig. After verification of the global response prediction, the developed global-local modeling strategy is used to evaluate the damage progression at a critical location with a detected initial defect.
Vibratory Loads/Stress Analysis and Fatigue Alleviation with Rotorcraft Comprehensive Modeling Tool

Published: June 2023

The primary cause of rotorcraft component fatigue is the vibratory loads from the rotors. Rotorcraft constantly experience time varying loads even in steady state flight. The source of excitation is the unsteady airloads due to the combined effect of rotor rotation and flight speed. In aggressive flight maneuvers, critical loads are experienced, which may induce large structural stress response and, hence, severely impact the fatigue life of certain critical structural components (e.g., swashplate control pitch link, rotor blades, etc). This paper addresses the application of the FLIGHTLAB high fidelity comprehensive modeling and analysis tool to rotorcraft vibratory loads and stress analysis and active control methods for fatigue alleviation. Through this study, a fatigue reduction controller was designed. The prototyped controller was integrated with FLIGHTLAB and the effectiveness of the control method for fatigue reduction was tested and evaluated for selected critical rotor components (e.g., blade, hub, and pitch link) and flight maneuver conditions.
