Aircraft Load Estimation Using Linear Parameter-Varying System-Based Hybrid Observers
Authors: Luderer Oliver , Thielecke Frank
Published: February 2025

The hybrid loads observer has demonstrated its precision in estimating structural loads and wind disturbances in prior applications. This level of precision is attained by combining a high-fidelity physical, nonlinear flight dynamics model with a data-driven correction model. To mitigate the typically high computational effort, the nonlinear model is substituted in this work with a linear parameter-varying (LPV) system. Therefore, the nonlinear model is approximated by scheduled Linear Time-Invariant models derived from Jacobian linearization. The robustness of this novel approach against parameter uncertainties is evaluated through simulated flight test studies using a subscale test aircraft as an example. It is demonstrated that increased model uncertainties lead to wind estimation accuracy reduction. Additionally, increased parameter uncertainties adversely affect the accuracy of structural load estimation within the model-based (physical) part of the observer. Nonetheless, this loss of accuracy can be compensated by the correction model, leading to the typical high load estimation accuracy of the hybrid loads observer. Finally, experimental data from wind-tunnel tests, utilizing a 1-degree-of-freedom representative test wing, confirms the high estimation accuracy of the LPV-based hybrid loads observer. Despite employing low-fidelity models, achieving high accuracy is feasible while maintaining the characteristic low complexity of the correction model.
In-Air Trapped Static Method for Aircraft Pressure Altitude and Airspeed
Authors: Luo Jia
Published: February 2025

Accurate aircraft airspeed measurement has always been crucial for analyzing, testing, and certifying aircraft performance, handling qualities, loads, flutter, and structural integrity. Indicated or calibrated airspeed, determined by impact pressure, relies on total pressure from the pitot tube and static pressure from the static port(s), both susceptible to distortion by local flow near the pressure sensors. Various methods used for measuring static pressure have either been expensive to operate or suffered from degraded accuracy and efficiency. This paper introduces the In-Air Trapped Static (IATS) method for computing accurate static pressure and airspeed from a pressure altitude profile anchored at identified trapped static points. The pressure altitude profile is constructed using kinematically corrected geometric altitude and a local temperature profile extracted from recorded flight data. The author hopes that this method, with its significantly enhanced airspeed accuracy, will promote consistency in aircraft development and certification for both manufacturers and regulatory agencies, thereby improving the safety of aircraft operation.
Interactional Aerodynamics of Single Main Rotor Helicopters in Steady Autorotation
Authors: Tran Steven A. , Lopez Mark J.S.
Published: February 2025

Autorotation is an edge case flight regime where, instead of being powered by an engine, a rotorcraft is powered purely by the air moving up through the main rotor as the vehicle descends. In this paper, a full-vehicle UH-60A helicopter is simulated in steady autorotation using both the flight dynamics (FD) code HeliUM-A and the computational fluid dynamics/computational structural dynamics (CFD/CSD) solver CREATE-AVTM Helios. The CFD/CSD simulations model the full-vehicle geometry and are trimmed to an autorotative state that is representative of how the aircraft flies in practice. Despite significant differences in the predicted airloads, both FD and CFD/CSD predictions of the vehicle’s autorotational descent rate were in excellent agreement with available flight test data. CFD/CSD analysis further examined mutual interactions between the helicopter’s rotors and various airframe components. The airframe plays a critical role in determining the aircraft’s autorotational descent rate and its shed wake creates regions of loading loss in the rotor disk. On the other hand, the main rotor induces significant unsteadiness on the airframe loading and creates an effective downforce on the fuselage and stabilator.
Improved Aircraft Environmental Impact Segmentation via Metric Learning
Authors: Gao Zhenyu , Behere Ameya , Mavris Dimitri N.
Published: February 2025

Accurate modeling of aircraft environmental impact is pivotal to the design of operational procedures and policies to mitigate negative aviation environmental impact. Aircraft environmental impact segmentation is a process that clusters aircraft types that have similar environmental impact characteristics based on a set of aircraft features. This practice helps model a large population of aircraft types with insufficient aircraft noise and performance models and contributes to better understanding of aviation environmental impact. Through measuring the similarity between aircraft types, a distance metric forms the kernel of aircraft segmentation. Traditional ways of aircraft segmentation use plain distance metrics and assign equal weight to all features in an unsupervised clustering process. In this work, we utilize weakly supervised metric learning and partial information on aircraft fuel burn, emissions, and noise to learn weighted distance metrics for aircraft environmental impact segmentation. We show in a comprehensive case study that the tailored distance metrics can indeed make aircraft segmentation better reflect the actual environmental impact of aircraft. The metric learning approach can help refine a number of similar data-driven analytical studies in aviation.

Authors: Nuraini Aisyah , Indarti Fitri Dwi
Published: February 2025

One of the architectural styles that underwent significant evolution was the Gothic style, which later developed into Neo-Gothic or Gothic Revival. These changes are influenced not only by aesthetic factors but also by social, technological, and political advances in various periods. The Neo-Gothic architectural style emerged in the late 18th to early 20th centuries as a revival of Gothic architecture from the medieval era. St. Joseph Gedangan Catholic Church in Semarang is one of the historical buildings registered as a cultural heritage, which carries a Neo-Gothic architectural style with a little Gothic touch. This study uses a qualitative method based on case studies to examine the transformation of architectural styles in St. Joseph Church Gedangan Semarang. This church adopts the Neo-Gothic style, which results from a transformation of the Gothic style that developed in Indonesia. This process of change illustrates how European architectural styles can be adapted to local conditions in Indonesia. St. Joseph Gedangan Church retains the typical elements of Gothic architecture but is adapted to the climate of Semarang City. The materials are available, and the size of the building is more proportional compared to traditional Gothic buildings. This change reflects the advancement of technology as well as the functional needs of church buildings in Indonesia that combine the beauty of classical architecture with modern efficiency.

Authors: Safira Lutfiana Devi , Kinasih Kania
Published: February 2025

The park at Universitas Muhammadiyah Semarang still does not fully meet the needs of blind people, because it still lacks guiding blocks, as well as the lack of other supporting elements that can hinder their ability to move. Thus, it is necessary to recommend a design solution that can improve access for blind people, especially on the path to the At-Taqwa Mosque. Against this background, this research seeks to design a guiding path for the visually impaired and signage that suits their needs in the green open space leading to the At-Taqwa Mosque. The design will consider the use of guiding blocks and braille signage as direction and information guides. An inclusive design plan is implemented so that all users, including people with other disabilities and the general public, can benefit optimally. The solutions proposed in this research, such as the addition of guiding blocks for navigation and a Braille signage as inclusive information, are designated based on universal design principles in Unimus’ green open space. The implementation of this solution not only supports the needs of the visually impaired but also creates an inclusive, comfortable, and accesible green open space for all campus users.

Substantiation of indications for limb amputation in civilian victims with multisystem injuries as a result of modern warfare
Authors: Guryev S. O. , Kushnir V. A. , Solovyov O. S. , Panasenko S. I.
Published: February 2025

Objective. To define standardized criteria for the need for limb amputation in civilian victims with multisystem injuries as a result of modern warfare
Materials and methods. The total study population of 2122 victims with injuries as a result of current hostilities in eastern Ukraine after the full–scale invasion of Russian troops into our territory from February 2022 to November 2024 was studied and analyzed, of whom 1069 (50.38%) had limb injuries. The study population was formed by irreversible randomization based on the combination of the victim's civilian status and limb injury as a component of a polysystemic injury.
Results. An original standardized assessment system based on an organic combination of assessment of signs of direct limb damage and signs of general damage was developed. This allows for an objective assessment of limb injury as a component of multisystem damage. It is especially important that this approach makes it possible to determine the safety of preserving the limb for the victim's life. It was found that the question of the need for limb amputation arises in victims with a general condition score of more than 20 points on the original standardized scale, and it depends on the clinical and anatomical signs of injury. Thus, the highest risk of amputation – 62% – is for forearm injuries in victims with a general condition score of more than 30 points, and for injuries to the lower leg and foot, i.e. the distal parts of the lower limb, this figure is 41.18 and 42.86%, respectively. It was also found that in victims whose condition was assessed as extremely severe, the incidence of lower limb injuries was 64.46%, in particular, 16.82% of the thigh and 30.84% of the lower leg. In general, injuries to the lower extremities are considered to be the most severe
Conclusions. Formation of indications for amputation of limbs in civilian victims with polysystemic injuries as a result of modern combat operations requires a standardized approach based on objective evaluation criteria. Not only the condition of the limb should be assessed, but also the general condition of the victim, as combat trauma to the limbs is polystructural and polysystemic. When interpreting the assessment of the need for limb amputation, the priority should be given to the principle of preserving the life of the victim, not the damaged limb, so the use of combined standardized assessment systems is justified.

Objective. To analyze the distribution of patients with tibia fractures by treatment methods during the COVID–19 pandemic and determine its changes compared to the pre–COVID period.
Materials and methods. The methods of treatment of 289 patients with trauma at the Kyiv City Clinical Emergency Hospital from 2019 to 2021 were retrospectively analyzed. Damage to the lower leg bones was detected in 83 (28.7%) patients.
Results. During the COVID–19 pandemic, the frequency of surgical treatment of patients with proximal tibia fractures more than halved, and the frequency of conservative treatment increased more than 4 times, which is in line with global trends in the treatment of this type of injury during the pandemic. The number of patients with diaphyseal fractures of the tibia who underwent surgical treatment decreased by 1.4 times. Conservative methods of treatment were prioritized, as evidenced by a 3.7–fold increase in the frequency of this type of treatment compared to the period before the pandemic. In patients with fractures of the distal tibia, surgical treatment was used 2.5 times less often than in the period before the pandemic. The opposite trend was observed in relation to conservative treatment methods: the number of patients who received such treatment increased 4 times.
Conclusions. During the COVID–19 pandemic, the number of patients with traumatic injuries of the lower leg, including all localizations except for the ankles, significantly decreased, with more patients having such injuries during this period. Epidemic restrictions and mechanisms for screening patients with tibia fractures of all localizations during the COVID–19 pandemic have changed approaches to their treatment towards the wider use of conservative methods.

Published: February 2025

The spread of radicalism in educational institutions, particularly in Islamic boarding schools, is often attributed to institutional leaders who promote a rigid interpretation of religion. The pivotal role of Kiai (Islamic scholars or leaders) and teachers in these schools is central to developing students’ attitudes toward Rahmatan lil alamin (mercy for all creation) and fostering a moderate perspective. As a role model, Kiai plays a significant role in cultivating a sense of moderation among Santri (students). This article aims to describe and analyze the leadership strategies employed by Kiai in this context. The research adopts a qualitative design with a case study approach and was conducted at the Amanatul Ummah Islamic Boarding School in Pacet, Mojokerto, East Java. The findings highlight several key strategies Kiai Asep Saifuddin Chalim implemented, including strengthening Nahdatul Ulama traditions, implementing a rigorous selection process for teachers and Staff, adhering to fundamental principles of success, and integrating moderate values into the school curriculum. Furthermore, the Kiai’s exemplary leadership supports the development of a wise and balanced attitude among Santri.

The article deals with the issues which were raised at international
scientific conferences with the participation of experts from Tanzania, Russia
and other countries, organized in Dar es Salaam in March 2022 and 2024 by
the Ministry of Science and Higher Education of the Russian Federation, the
Russian Academy of Sciences, the Institute of Africa of the Russian Academy
of Sciences, the Federal Agency for the Commonwealth of Independent States,
Compatriots Living Abroad and International Humanitarian Cooperation, the
Russian Center for Science and Culture in Dar es Salaam together with the
Mwalimu Nyerere Memorial Academy and the University of Dar es Salaam.
The first, “Leadership and Power in Africa in the past and present. Research
by scientists from Russia, Tanzania and other countries”, commemorated
the 100th anniversary of the founding father of Tanzania, Julius Kambarage Nyerere. The second – “Africa’s Place in the World. The past and present” –
took place in 2024, on the eve of the 60th anniversary of the formation of the
United Republic of Tanzania, celebrated on April 26.
The collections of abstracts of reports published by the Institute of Africa
of the Russian Academy of Sciences following those conferences cover an
extremely wide thematic spectrum – from the place of African countries in
the modern world to the transformation of their power institutions, political
elites, state languages and culture, their influence and interrelation with global
processes.
The authors using unique archival and periodical material, focus on global
civilizational aspects, give a comprehensive analysis of the role of Africa in
today’s world, drawing attention to the issues of power and society relations,
the specifics in the formation and functioning of elites in the modern political
and economic situation in different countries of Africa and the continent as a
whole. The conducted research makes a significant contribution to a broader
and more panoramic understanding of the issues raised in the context of
strengthening the African theme in modern discourses.

In the modern world, information technology plays a key role in the
life of society, and information security becomes a critically important aspect for
the functioning of organizations. This article examines the evolution and modern
trends in the protection of automated information systems from computer attacks,
considering the implementation of distributed information processing based on
network IT infrastructures. The development context includes tools and systems
for intrusion detection and prevention (firewalls, IDS, and IPS), starting from
their simplest implementations to modern integrated solutions. When considering integration, issues of correlating security breach identification indicators and
consolidating security status monitoring data obtained by various protection tools
and systems are highlighted. The advantages of NGFW, such as enhanced functionalities, integration with other systems, flexible security policy configuration,
and reduced total cost of ownership, are discussed. In the context of import substitution, examples of Russian solutions in the field of NGFW are considered, such as
Ideco UTM, InfoWatch ARMA Industrial Firewall, UserGate, and “Kontinent 4”.

Pengembangan aplikasi berbasis blockchain memiliki potensi untuk merevolusi transparansi dan ketertelusuran rantai pasok. Makalah ini menyajikan pengembangan Ricetrack, sebuah aplikasi berbasis blockchain dan QR Code yang dirancang untuk meningkatkan transparansi dan ketertelusuran dalam rantai pasok beras. Ricetrack dikembangkan menggunakan teknologi Hyperledger Sawtooth dengan metodologi Agile Blockchain DApp Engineering. Aplikasi ini diprototipekan dan diuji dalam rantai pasok beras di Menata Citra Selaras, Kabupaten Bekasi, Indonesia. Sebelum Ricetrack, ketertelusuran dan transparansi data sangat minim atau hampir tidak ada, dengan catatan yang dipelihara secara manual menggunakan kertas dan/atau Microsoft Excel. Pengujian prototipe menunjukkan peningkatan signifikan dalam ketertelusuran, transparansi data, dan efisiensi operasional. Temuan utama meliputi peningkatan kemampuan melacak beras dari petani hingga konsumen, peningkatan akses data real-time bagi pemangku kepentingan, dan pengurangan kesalahan serta waktu dalam proses pencatatan data. Studi ini menawarkan wawasan berharga tentang tantangan praktis dan manfaat penerapan teknologi blockchain dalam manajemen rantai pasok serta menyediakan dasar untuk peningkatan lebih lanjut dan implementasi Ricetrack yang lebih luas di masa depan.
