Authors:   Jena-Optronik GmbH, Jena, Germany, Kämpfe Thomas , Schmitt Christoph , Windmüller Michael , Schwarz Michael , Möller Max 
Published: January 2024

The RVS®3000 LIDAR product family is regularly used for retro tracking during flights to the international space station since 2019. A version for operation without retro reflectors used powerful algorithms and hardware for autonomous 6-Degree-of-Freedom (6DOF) pose estimation to enable satellite-servicing during Northrop Grumman’s (NG) Mission Extension Vehicle (MEV) program. For the Artemis Missions, the RVS®3000 LIDAR product family shall serve as primary relative navigation sensor on the ORION vehicle. The combination of high-resolution scanning LIDAR with robust image processing algorithms shall enable rendezvous and docking with e.g. Gateway.
Here we present the generic LIDAR system design as it was developed by Jena-Optronik GmbH for a variety of missions. This design will be introduced by the example of a rendezvous vehicles. Here we start from tracking of available retro reflectors from several kilometres down to autonomous 6-Degree-of-Freedom (6DOF) pose estimation with the docking port at close range. The algorithms exploit the full capability of the hardware by making use of “the best from the two worlds” of retro reflector tracking and model-based 6DOF pose estimation. This presentation will summarize simulation and test results.

Published: January 2024

In the design phase of a new launch vehicle, the stiffness budget analysis represents an essential task. Indeed, during its flight, the launcher is subject to significant external forces which may lead to instability. As a consequence, the stiffness of each item of the launch vehicle has a fundamental impact on the definition of the global bending modes’ parameters and on the fulfilment of the launch vehicle control stability requirements. In this context, this article focuses on a sensitivity analysis to the stiffness budget robustness, obtained by varying each item’s stiffness and computing the launch vehicle worst-case stability margins.
The VEGA-E (Evolution) launcher has been considered as a benchmark for the activity under study. Indeed, this launcher is currently in the second development phase and lends itself well to this type of analyses that could lead to improvements in its design.
The analysis proposed in this paper allows to graphically assess which parameters mostly affect the fundamental bending modes’ eigenfrequencies and shapes and to approximate the impact of stiffness budget changes in terms of launch vehicle performance in view of mass saving optimizations.
A set of stiffness budget alternates has been considered and an uncertain Linear Fractional Representation (LFR) of the launch vehicle has been defined for each different design case. It is worth to underline that, since the slosh masses are not deterministically known by the Finite Element Model (FEM), the bending modes have been computed considering three different values slosh masses (minimum, nominal and maximum). Moreover, considering that the payload mass represents another factor that adds variability to the bending modes’ parameters, two different payload configurations (minimum and maximum) have been considered in the FEM model.
With this set-up, the structural stiffness needs have been verified with respect to the control related requirements by examining all the considered data sets from the stability point of view. Since the stiffness variations mostly affect the bending modes, for each case taken under study a tuning of the bending filter has been performed using the structured H∞ technique.
To fasten up computations, it has been assumed that the worst-case tuning condition is to be the least controllable design point according to the aerodynamic to thrust efficiency ratio.
Results have shown that this strategy makes it possible to ease the controllability constraint in the stiffness budget optimization, allowing a possible improvement in terms of performance and guaranteeing at the same time the fulfilment of the required worst-case stability margins.

Published: January 2024

Nowadays, primarily conventional reaction wheels are used to control the attitude of spacecrafts. Nevertheless, some missions require the attitude control to be much more agile. Due to their functional principle Control Moment Gyroscope (CMG) based control systems provide a much higher agility and are thus getting more and more important.
Astro- und Feinwerktechnik Adlershof GmbH (Astrofein) is currently developing a CMG for Small Satellites supported by ESA GSTP-6. To make CMGs available for smaller satellites, a trade-off between volume and mass as well as power consumption and performance had to be made. The current design ensures a high target performance of 8Nms/14Nm with a dedicated mass of 8kg and a maximum power consumption of about 40W. An Engineering Qualification Model (EQM) was built and is currently undergoing an environmental test campaign, that includes different tests such as the Thermal-Vacuum and Micro Vibration test. The specification and the current status of the CMG as well as an insight on the test results with regards to the performance of the CMG within the environmental tests will be given in this paper.

Published: January 2024

The Leonardo SPACESTAR product is going to be updated with the main goal of reducing size and mass (Mini Spacestar) while maintaining the same performance and flight heritage of a well consolidated product, with hundreds of units flying since many years.
The Mini Spacestar updated electronics will be even more compact than before and still dedicated to APS control and image pre-processing, while a SW (delivered by Leonardo) embedded in the central AOCS computer will calculate the quaternions. As a result, the Mini Spacestar confirms the same architectural configuration of SPACESTAR, which already demonstrated to provide a significant reduction of recurring costs at AOCS level thanks to CPU resources sharing.
The Mini Spacestar electrical I/F and data I/O will remain unchanged with respect to the predecessor, to allow replacing at zero cost in the platforms that already adopted this product.
The Mini Spacestar will be available either with components fully space qualified (for missions with high reliability requirements), or in a configuration based on “New Space” components. The “NS” Mini Spacestar will provide adequate quality and resistance to radiations through components efficiently selected or locally shielded, at the same time allowing a significant reduction of recurring costs and meeting the requirements of the “New Space” Missions.
Finally, thanks to its high performance and reduced dimensions, the Mini Spacestar is suitable to be integrated directly on the optical bench of observation payloads (e.g. Optical payloads) to increase System pointing (and geolocation) performances, where required. Studies are in progress at Leonardo and some highlights will be given as part of the paper.

Published: January 2024

The RW6000 is the first wheel of Astrofein's newly developed family of smart high-momentum reaction wheels that has been fully qualified. The 100 Nms wheel makes use of Astrofein's heritage wheel technologies like the flexible structure concept and smart functions as closed-loop speed and torque control. As all of Astrofein's reaction wheels it is open to the environment (not hermitically sealed).
Even if, the wheel is based on exiistng heritage, Astrofein faced several challenges during the development. This included challenges related to qualifying new technologies like the lead-free assembly process for the wheel drive electronics and the identification and qualification of automotive grade EEE parts. But, also scaling effects related to the wheel size were underestimated, like air drag effects during ground testing. Other challenges were mission related. One of these mission related challenges was the development of a critical SW for driving and controlling the wheel.
The paper will provide some details on the challenges faced during the development and how they have been solved. Furthermore, it gives details of the key performance parameters of the wheel and the performed qualifications. Finally, it will give an outlook what possible further improvements are planned and how the achievements will be utilized for other wheels in Astrofein's family of high-momentum reaction wheels.

Published: January 2024

While the role and benefit of perioperative intravenous (IV) antibiotics in patients undergoing total joint arthroplasty (TJA) is well-established, oral antibiotic use in TJA remains a controversial topic with wide variations in practice patterns. With this review, we aimed to better educate the orthopedic surgeon on when and how oral antibiotics may be used most effectively in TJA patients, and to identify gaps in the literature that could be clarified with targeted research. Extended oral antibiotic prophylaxis (EOAP) use in high-risk primary, aseptic revision, and exchange TJA for infection may be useful in decreasing periprosthetic joint infection (PJI) rates. When prescribing oral antibiotics either as EOAP or for draining wounds, patient factors, type of surgery, and type of infectious organisms should be considered in order to optimally prevent and treat PJI. It is important to maintain antibiotic stewardship by administering the proper duration, dose, and type of antibiotics and by consulting infectious disease when necessary.
“The war depends on you”: Suicidal Romanticism in Jeff Buckley’s Grace
Authors: McConville James 
Published: January 2024

ABSTRACT
In recent decades, scholars including Jerome McGann and Anne K. Mellor have interrogated the previously stable borders of various moments of literary criticism and philosophy, including Romanticism and its consideration of conflict, unity, and identity. Such interrogation has resituated texts not traditionally associated with the Romantic period in new theoretical lights. Surveying landscapes of contemporary sensibilities of masculinity, this article will argue that the central figures in Jeff Buckley’s Grace represent a trope in Romantic texts the author has developed from Nicholas Saul’s exploration of “Romantic suicide.” Suicidal Romanticism encapsulates Buckley’s subject in its search for an authentic and unique identity and eventual disavowal of identity altogether. McGann’s widening of the Romantic landscape provides credence for broader swaths of connection between cultural periods, literary criticisms, and textual forms, situating artists like Buckley within the bounds of a Romanticism engrossed in the examination of conflicted personalities searching for meaning and wholeness.

O presente estudo teve por intuito conhecer o papel do enfermeiro nos cuidados imediatos ao recém-nascido (RN). Os recém-nascidos são muito vulneráveis a doenças na primeira semana de vida, onde um grande número de crianças morre logo após o nascimento. Uma criança tem cerca de 500 vezes mais probabilidade de morrer no primeiro dia de vida do que com um mês de idade. Como metodologia foi utilizada a revisão bibliográfica em livros e artigos científicos sobre o tema, tendo como base de dados a Biblioteca Virtual em Saúde (BVS). Percebeu-se com os estudos que os enfermeiros em geral sabem como realizar as ações, destacando que apenas um estudo evidenciou tanto um déficit no que tange as ações realizadas por profissionais como a categoria de técnico em enfermagem, quanto também que a capacitação dos profissionais envolvidos nos primeiros cuidados é de suma importância para uma assistência efetiva ao RN, evitando a mortalidade neonatal.
Analysis of Fiscal Policy and Monetary Policy during Covid-19 Crisis---an Australian perspective
Authors: Hu Yutong 
Published: January 2024

The outbreak of new coronavirus pneumonia in 2020 has emerged as a significant global epidemic, representing a profound disaster. All nations encounter a shift towards crisis management frameworks, exhibiting variable levels of success in limiting the spread of the virus and mitigating economic repercussions. This is by far the most far-reaching public health event of the 21st century on a global scale, with immeasurable research significance from immunological, economic, and sociological perspectives. For the continent of Australia, which is alone in the ocean, the Australian community could not carry the blow once the epidemic exploded across the country. So, as early as the 20th of March, Australia quickly declared a "border closure", banning all non-Australian citizens and non-permanent residents from entering the country. Moreover, with regard to the movement of persons, production activities and control of cases and close contacts in the region, each oblast has adopted restrictive measures of varying degrees, depending on the severity and development of the outbreak. The special geographical conditions and the policy of a completely closed borderline allow us to value the effectiveness of the Australian government's and banks' response to the stimulus provided by the COVID-19 policy directly by removing most of the external conditions from the equation.
Changes and Impact of Monetary Policy in the United States: Quantitative Easing and Federal rate hikes
Authors: Chen Zhihao 
Published: January 2024

In response to the 2008 financial crisis, marked by the collapse of Wall Street giants like Bear Stearns and Lehman Brothers, the U.S. faced significant economic challenges. Traditional monetary policy tools proved ineffective as interest rates neared the Zero Lower Bound. Consequently, the Federal Reserve implemented Quantitative Easing (QE) as an unconventional measure to stimulate financial markets. This policy was executed in four phases, and by the end of the fourth round, U.S. inflation rates surpassed the 2022 target. Elevated inflation impacted living standards, prompting the FED to introduce interest rate hikes in 2022 to control it. Supply chain disruptions were a major contributor to this inflation spike. This paper uses qualitative and statistical methods to explore QE and the subsequent FED rate hikes. It emphasizes that QE essentially expanded the FED's Balance Sheet and uses visual data like graphs to illustrate the FED's actions since 2022. The article provides a comprehensive view of U.S. monetary policy adaptations during and after the financial crisis. The first three QE rounds addressed the 2008 crisis aftermath, while QE4 combated the economic fallout of COVID-19. The 4 rounds of QE and the last 2 years of Fed rate hikes have been generally successful. Both monetary policies have had some proven effect on the US economy. However, by critical thinking, QE has potential downsides, like fostering economic bubbles and inflation. And the Fed's repeated interest rate hikes have led to the problem of bank failure. Therefore, the Fed's monetary policy choices, especially unconventional ones like QE, require weighing benefits against potential risks.

The United Nations Climate Dictionary states that “climate change is the defining issue of our times”. According to this Dictionary, we are facing a global crisis which “refers to the serious problems that are being caused, or are likely to be caused, by changes in the planet’s climate, including weather extremes and natural disasters, ocean acidification and sea-level rise, loss of biodiversity, food and water insecurity, health risks, economic disruption, displacement and even violent conflict”. These changes affect health, ability to grow food, housing, safety and work. In one word: the entirety of life as lived by both humans and non-humans in the world. The global nature of this condition, however, does not mean that every population is affected in the same way or at the same time. Some communities across the world have already been damaged by the consequences of the environmental crisis, while others will likely be affected in the future. Those who are not currently directly affected by these changes will still be affected indirectly. In other words, since the environmental crisis is a global phenomenon, it also produces global consequences, such as increasing migration.
INDIAN HIGHER EDUCATION SYSTEM: ASCENDANCY OF HEGEMONIC CULTURE AND INTERNATIONAL MULTICULTURALISM
Authors: FAROOQI SNA 
Published: January 2024

Through this study researcher wants to find relationship between two dependent variables, i.e., hegemonic culture and international multiculturalism with that of independent variable, i.e. Indian higher education system. Since it becomes very important to know what effect multiculturalism and hegemonic culture have on our higher education system so that we can have more culturally responsive classroom practices in place. For this research, data was collected from university level teachers working at various positions like Professors, Associate professors, and Assistant professors. Full-time college faculty members made up the bulk of the data collecting samples. The information was gathered using a survey.
All dependent variables i.e., hegemonic culture (0.010), international multiculturalism (0.02) have significant positive impact on the independent variable i.e., Indian Higher Education system, it was also observed that hegemonic culture (0.010) have the least impact on Indian higher education system.
We see CRT in educational environments as all about leveraging diverse ethnic groups’ culture and experiences to educate more effectively. A culturally responsive classroom must allow children to keep maintaining both their academic success and their cultural identity. This research contributes towards a theoretical framework which is based on CFA Modelling of construct variables. In this we try to find out relationship between dependent variables like hegemonic culture, what is the role of an experienced teacher in facilitating culturally diverse classrooms and international multiculturalism on independent variable i.e., Indian higher education system.
