Authors:   Delft University of Technology and Politecnico di Milano, Nabi Hafiz ,   Politecnico di Milano, Quaranta Giuseppe ,   Delft University of Technology, Visser Coen , Pavel Marilena
Published: July 2023

A safe conversion of tiltrotor from helicopter mode to airplane mode is ensured through maneuvering within the conversion corridor, a constrained region in the airspeed versus nacelle angle graph. This paper presents preliminary work in the development of an automatic conversion maneuver. A high order quasi-Linear Parameter Varying model is developed for XV-15 that combines discrete state-space models to provide a varying model dynamics and trim characteristics during the conversion maneuver. Tracking control system based on gain scheduled linear quadratic tracker with integrator (LQTI) is designed for automatic conversion maneuver for XV-15 based on the qLPV model. Lastly, an optimization routine is performed to fly various conversion trajectories and identify optimal conversion maneuver.

Published: July 2023

In this paper, previously developed flight envelope protection algorithms and an active control system are integrated in a simulator environment and used as a limit avoidance evaluation framework for fly-by-wire helicopters. A force feedback map is developed and used in a new simulator environment to cue pilots against load factor limits. Adaptive models are developed online and used to calculate allowable control travels on the cyclic controls due to approaching load factor limits. The developed framework is demonstrated for load factor limit avoidance in different simulation scenarios.

Published: July 2023

The present work provides the results and findings from continuing research investigations into the high-speed mission task elements (MTEs) for Future Vertical Lift configurations. This study focuses solely on the recently proposed break turn MTE, an aggressive heading change performed at high forward speeds. All prior development and testing of this MTE had been performed in simulators with advanced rotorcraft configurations. The goal of the present study was to conduct a limited-scope flight test assessment of the break turn MTE. The MTE was flown with two helicopters (the UH-72A and UH-60L) and one fixed-wing airplane (the T-6B) to demonstrate how the MTE and its performance criteria applied to aircraft of varying performance and operational limitations. In the design and conduct of the test, a build-up/build-down philosophy of testing was applied to ensure that aircraft limitations were approached deliberately. Additionally, the maneuver conditions were modified in the present study to ensure that the MTE was an assessment of handling qualities alone, i.e., not aircraft performance. The study demonstrated that the break turn MTE is a suitable maneuver to evaluate high speed handling qualities for rotorcraft with the appropriate performance considerations, and the maneuver course layout provided adequate cueing to the pilots.

Published: July 2023

Shipboard rotorcraft operation places significant demand on pilot workload, which can be compounded by harsh environmental conditions. While prior research into characterizing pilot behavior and aircraft handling qualities during shipboard operations has relied on data from flight tests and manned flight simulations, the present work is focused on analysis of a large dataset of operational helicopter data, detailing both ship and shore landings, in order to improve the understanding of helicopter operations and provide the basis for a data-driven assessment of pilot activity. The operational data was classified into two datasets (shipboard landings and shore-based landings) through an automated analysis of the aircraft state parameters. Each dataset was analyzed to produce aggregate landing approach profiles and aggregate representations of pilot control input to facilitate characterization and comparison of the fleet norms for the two sets of landings. The aggregate landing approach profiles showed clear distinctions between the pilot techniques employed in the ship and shore landings, revealing much more uniformity in the execution of the ship landings. The aggregate pilot control input analysis also exposed striking differences in control input activity, with ship landings characterized by higher magnitude, higher frequency control input. Together, these results not only corroborate prior research into qualitative assessments of pilot workload through time-frequency representations, but they also provide a benchmark against which data from other landings (whether operational, flight test, or manned simulator) may be evaluated to determine the efficacy of training procedures or possible changes in rotorcraft handling qualities, particularly in the shipboard environment.
Novel Diagnostic Metrics for Regime Recognition Verification and Validation
Authors:   Georgia Institute of Technology, Warner Jonathan , Rogers Jonathan
Published: July 2023

Lifecycle management for many commercial and military helicopters involves the process of regime recognition (RR), in which the maneuver history of the aircraft is classified into individual regimes over the duration of a flight. When considering verification and validation (V&V) for regime recognition codes, a key step lies in assessing the RR code's conformance to defined classification and damage prediction accuracy requirements. The confusion matrix is typically used for this purpose; however, the confusion matrix does not quantify certain critical aspects of RR code performance and oftentimes fails to provide actionable information about how a code may be improved. This paper describes a novel set of V&V diagnostic metrics designed to highlight areas of deficiencies in the algorithm and specific paths to code improvement. These metrics leverage pattern recognition techniques to align the flown and recognized maneuvers and are proposed to supplement and enhance the V&V information obtained from the confusion matrix. Several example V&V flight sequences are provided to highlight the benefits of the proposed diagnostic metrics when used in concert with other classical V&V tools.
Low Computational, Nonlinear Component Trend Analysis
Authors:   GPMS Inc., Bechhoefer Eric
Published: July 2023

This paper is concerned with a nonlinear, computationally efficient method for trending component health. While conceptually simple, the goal of component trending is to reduce spurious noise in the measured component health and to estimate the remaining useful life (RUL). The need for lower computational effort allows this to be done on an embedded system. This would be important for display on a cockpit multi-function display. Additionally, we describe a new method for state smoothing. This is a forward-backward technique with no computational overhead associated with updating the plant noise (associated with a Kalman Smoother), significantly reducing the number of operations needed. Finally, a comparison is made between the precision of the nonlinear state estimation vs. a linear state estimation in the computation of the RUL. The precision was quantified using mean relative of the prognostic.

Published: July 2023

Machine learning is employed to reconstruct vibration spectra from the condition indicators recorded by a field data acquisition system. Those spectra are used to compute a custom condition indicator, enabling the expansion of an on condition part life extension program to many more rotorcraft. This alternate, machine-learning driven method for computing an existing condition indicator is submitted for rigorous testing and qualification, and for fielding to the fleet analytics system.
Ludwig, Rudolf and Emil Rüb: Forgotten German Aeronautical and Rotating-Wing Pioneers
Authors:   German Aerospace Center (DLR), G. Berend
Published: July 2023

Ludwig Rudolf Rüb, a passionate inventor, lived in poverty most of his life and is virtually unknown in the rotorcraft community. His inventions covered combustion engines and motorcycles first. Around 1900 he built a paddle-wheel plane under contract by Count Zeppelin, next he designed and built a first version of a coaxial rotor helicopter in Munich, and then he moved to Augsburg for building a large fixed-wing aircraft. None of these were ever finished. At the begin of WW I, with support of the German army, he took up a refined version of his coaxial rotor helicopter concept as a highly agile and maneuverable replacement of the observation balloons used in those times, which also was intended to take an active part in warfare by installing a machine gun or dropping bombs. It included some astonishing advanced features and with the help of his sons the construction was finished; ground testing started in June 1918. The end of the war immediately stopped all works; the contract of Versailles demanded the destruction of that vehicle and thus formed the end of the Rüb aeronautical work. Ludwig Rüb died 1918, after months of illness, without having seen the rotors turning.

Commonly associated with the accurate representation of reality according to a specific ratio, which depends mainly on measuring and precision, the notion of scale has been considered an operative tool in architecture to perceive and indicate the size of anything according to a reference system. An effort to challenge the concept of scale(ing) to include diverse reference units and their scalar articulations holds the potential of instigating novel associations in architectural design studios. Possible readings of these alternative scale(ing) conditions are discussed in the paper in reference to a series of design exercises conducted at architectural design studios. The main intention is to question these unmediated associations to the reference unit in the determination of size and proportion, thus possible scales of architectural space. This particular method of analysis aims to arrive at various scale(ing) conditions, whose internal reference system is challenged by the changes and shifts in the definition of the major reference unit. Each different scale(ing) condition studied through the given exercise was regarded as an act of confrontation for readings of scale as well as presenting provocative challenges to the architectural design processes. With this standpoint, the paper proposes a multi-layered reading of scale that argues the reference unit’s instrumentality in the definition of architectural space and proposes an alternative methodology of integrating scale in architectural design education.

The covid-19 pandemic which outbroke four years ago has shifted how people live, work, and shop. Governments restrictions have made people develop new habits that can be done from home. Fashion industry as one of the most influential industries in Indonesia, as well as something that was always being traded offline, becomes one of the impacted areas. The less bodily experience of fashion online shopping and more cost-conscious consumers made this industry experienced a dip especially in 2019 and 2020. However, preliminary findings suggest that this condition benefits local fashion businesses which have been operating online since before this problem emerged. Therefore, this study is conducted to investigate the post-covid-19 pandemic preferences of generation-Z consumers regarding local and global fashion brands, focusing on a cross-cultural comparison between Indonesia and the Netherlands. The research aims to understand the factors influencing Generation-Z’s fashion brand preferences and explore potential differences between the two countries. This study is done using quantitative method with online questionnaires tool distributed to a sample of generation-Z consumers from two universities in Indonesia and Netherlands. Then, the data is processed using partial least square-structural equation modelling (PLS-SEM). Results show that generation-Z of both countries prefer local fashion brands compared to global ones. The difference between the two countries is Indonesian participants emphasize the importance of brands interactivity, while the impact of it to Dutch participants is less significant. The study’s implications highlight the evolving Generation-Z consumer behavior after the pandemic especially the shift of preference to local fashion brands. Understanding these preferences can assist fashion business owners and marketing teams in tailoring their strategies to cater the current needs and values of Generation-Z consumers. Furthermore, the cross-cultural comparison sheds light for fashion business owners who are planning to expand their markets to developed countries with similar characteristics as Netherlands.

The Role of Crises in Human Development
Authors: Krokosz Ewa
Published: July 2023

Crises are often viewed negatively as disruptions that hinder individuals and social groups. However, crises can also present opportunities for growth and development. This article explores psychological concepts that perceive crises as catalysts for change, motivating individuals to seek help and find constructive solutions in difficult situations. The article examines various psychological theories on crises. It discusses the different ways individuals respond to crises, ranging from effectively managing them to experiencing mental breakdowns. Crises have complex symptoms and causes, influenced by personal and environmental factors such as family, workplace, material status, and social groups. Anxiety is a common characteristic of crises, often reaching a high level before individuals acknowledge the need for concrete actions. Quick fixes like medication provide temporary relief but do not resolve the underlying crisis. Crises often involve conflicts and decision-making, where passivity becomes a negative and destructive choice. The article also explores crises in developmental terms, drawing upon Erik Erikson’s psychosocial development theory and Kazimierz Dąbrowski’s theory of positive disintegration. Erikson identifies specific crises in each stage of development, while Dąbrowski emphasizes the role of tension and disruption in achieving higher levels of personal growth. Not all crises lead to development, and not all changes constitute developmental changes. Developmental changes are irreversible, sequential, autonomous, unidirectional, and goal-oriented. The article categorizes development into continuous, leap, and crisis development, highlighting the transformative nature of crisis-induced changes. The article argues that crises, despite their hardships, should be viewed as opportunities for personal and collective development. By confronting crises and actively seeking constructive solutions, individuals and communities can achieve higher levels of growth and improve their quality of life.

Improving Software Quality through Deep Learning: A Comprehensive Literature Study on Error Prediction in Software Development
Authors: Amna Shipra  , Avaish Ansari
Published: July 2023

The paper explores the significance of error prediction in software development and discusses the use of deep learning approaches to address this task. It emphasizes the need for proactive error prevention and the limitations of reactive bug- fixing strategies. The study examines various deep learning models, including Recurrent Neural Networks (RNNs), Convolutional Neural Networks (CNNs), and Graph Convolutional Networks (GCNs), and their applicability in error prediction. The conclusions drawn from the study highlight the strengths of each model. RNNs are effective in capturing temporal dependencies and sequential patterns in error data, enabling the analysis of error progression over time. CNNs excel at extracting relevant features and local patterns from software artefacts by treating them as image-like data. GCNs leverage the graph structure of software artefacts to capture structural dependencies and interactions between code elements. To leverage the benefits of both temporal and structural information, the study proposes a hybrid model that combines RNNs with GCNs for error prediction. This hybrid model harnesses the power of deep learning to identify patterns and model relationships, offering promising results in accurate error forecasting and prevention in software development. The adoption of proactive error prediction techniques facilitated by deep learning has the potential to enhance software quality, resource efficiency, and user experience. By proactively identifying and addressing errors, development teams can reduce the impact of issues before they manifest, leading to improved software reliability and customer satisfaction. Overall, the paper highlights the importance of error prediction in software development and demonstrates the potential of deep learning approaches to enhance error prevention strategies.

Mycorrhizae are beneficial soil microbes that form a symbiotic relationship with roots. The application of mycorrhizal inoculants with varied fertilizer rates on the performance of sweet corn was studied from December 2021 to March 2022 at Calao-calao, Don Carlos, Bukidnon. It aimed toquantify the concentration of NPK absorbed by the sweet corn planted. Generally, fertilizer rates have a positive effect on the concentration of phosphurus in sweet corn, whereas mycorrhizal inoculants have an effect on the concentrations of nitrogen, phosphorus, and potassium. Furthermore, the combination of fertilizer rates and mycorrhizal inoculants influences phosphorus concentration.
POLIGAMI DALAM PANDANGAN MOHAMMAD KHALIFA DAN ORIENTALIS
Authors: Syarifah Nurus
Published: July 2023

Abstract: This paper discusses polygamy proposed by Mohammad Khalifa and the orientalists in the book The Sublime Qur'an and Orientalism. In the view of Islam, the discourse of polygamy is often associated with QS. An-Nisa' verse 3. If it is seen from the asbab an-nuzul, according to the majority of scholars, this verse came down as an answer to the number of children who were abandoned by their fathers, and wives who were abandoned by their husbands due to the battle of Uhud. This paper is a library research using analytical descriptive methods and documentation techniques. From this research it can be concluded that, Mohammad Khalifa regarding the practice of polygamy, he is in line with what is stated by the majority of scholars. According to him, the practice of polygamy is devoted to widowers with the aim of helping widows and orphans who are victims of natural disasters, famine, and etc. Meanwhile, according to orientalists, there are those who say that the practice of polygamy is only a means to channel lust. There are also those who say that polygamy occurs so that husbands do not do deviant things to other women.

Keywords: Polygamy, Mohammad Khalifa, Orientalis, The Sublime Qur'an and Orientalism

 

Abstrak: Tulisan ini membahas tentang poligami yang dikemukakan oleh Mohammad Khalifa dan para orientalis dalam buku The Sublime Qur'an and Orientalism. Dalam pandangan Islam, wacana poligami seringkali dikaitkan dengan QS. An-Nisa' ayat 3. Jika dilihat dari asbab an-nuzul-nya, menurut jumhur ulama, maka ayat tersebut turun sebagai jawaban dari banyaknya anak yang ditinggal mati oleh ayahnya, dan istri yang ditinggal mati oleh suaminya akibat perang Uhud. Tulisan ini merupakan penelitian kepustakaan dengan menggunakan metode deskriptif analitis dan teknik dokumentasi. Dari penelitian ini dapat disimpulkan bahwa, Mohammad Khalifa mengenai praktik poligami, ia sejalan dengan apa yang dikemukakan oleh para jumhur ulama. Menurutnya, praktik poligami tersebut dikhususkan pada para duda dengan tujuan untuk menolong janda-janda dan anak yatim akibat korban dari bencana alam, kelaparan, dan lain sebagainya. Adapun menurut para orientalis, ada yang mengatakan bahwa praktik poligami tersebut hanya sebagai sarana untuk menyalurkan nafsu saja. Adapula yang mengatakan bahwa poligami terjadi agar suami tidak melakukan hal menyimpang pada perempuan lain.

Из официальных источников известно, что наша страна богата на природные ресурсы, в том числе на цветные металлы. Многие месторождения разрабатываются открытым способом с применением мощного горного оборудования, в этих условиях наиболее интенсивное пылевыделение происходит при экскавации взорванной горной массы.  Для снижения выделения пыли при этом процессе применяется орошение водой или водными растворами различных химических веществ. В полиметаллических карьерах пыль, выделяющаяся при работе горного оборудования, может содержать высокий уровень свободной двуокиси кремния, что указывает на ее высокую опасность для здоровья человека.  Кроме того, при разработка сульфидных руд, во взорванном навале часто наблюдается процесс самонагревание, которое может переходит в самовозгорание. Это приводит к потере полезных компонентов руды,ухудшению показателей обогащения, к экологическому и экономическому ущербу. В таких условиях применение чистой воды для снижения запыленности воздуха при экскавации не рекомендуется, так как она интенсифицирует процесс окисления сульфидных руд.Для увлажнения следует применять растворы комплексного действия, то есть  растворы обладающие как антиокислительными свойствами, так и обеспыливающим действием.Интенсивность окисления руды характеризуется температурным режимом взорванного навала.Отсюда следует, что характер влияния увлажняющей жидкости,выбираемой в качестве раствора комплексного действия, на интенсивность окисления руд можно оценить по изменению температуры увлажненного взорванного навала руды.  Рассмотрено уравнение  теплового баланса в скоплений сульфидных руд, склонных к самовозгоранию.Получено решение краевой задачи уравнения теплопроводности.Определено, что в температурном режиме взорванного навала руды  значительная  роль принадлежит плотности тепловых источников. Установлено,что ее величина определяется ,в основном, совокупностью констант скорости сорбции кислорода ( )  отдельными фракциями руды,составляющими взорванный навал. В зерне пористого сорбента имеется равновесие между скоростью изменения концентрации кислорода со временем и величиной, определяемой как разность между притоком кислорода в поры посредством диффузии и поглощением его из этих пор. Решено уравнение такого равновесия с учетом граничных условий.

With the increased realization that many wild medicinal and aromatic plant (MAP) Species are being over-exploited, a number of agencies are recommending that wild species be brought into cultivation systems. Others argue sustainable harvest to be the most important conservation strategy for most wild-harvested species, given their contributions to local economies and their greater value to harvesters over the long term. Besides poverty and the breakdown of traditional controls, the major challenges for sustainable wild-collection include lack of knowledge about sustainable harvest rates and practices, undefined land use rights and lack of legislative and policy guidance. Identifying the conservation benefits and costs of the different production system for MAP should help guide policies as whether species conservation should take place in nature or the nursery, or both.
