Es soll untersucht werden, ob die SAP BTP für KMU mit dem ERP-System SAP Business One im Einsatz, eine sinnvolle Möglichkeit bietet die digitale Transformation voranzutreiben. Es zeigt sich, dass die SAP BTP ein enormes Potenzial zur Unterstützung der Digitalisierung von KMU bietet, jedoch genaue Betrachtungen der Kosten erforderlich sind.

PT Dirgantara Indonesia (Persero) is an aerospace industry owned by the state. The accelerating speed of digital transformation nowadays has revolutionised businesses in how they digitally manage their information, automate processes, and enhance human capital productivity. The main aims for PT Dirgantara Indonesia are to reconcile the development strategies of HR and technological progress so that there is professional competence and organisational excellence in its workforce. This study explores the digital transformation principles that underlie HRM strategies in PT Dirgantara Indonesia. The study used a qualitative descriptive design, and the data were collected through field observations, interviews with HR managers, line managers, employees, and stakeholders.

A semi-structured interview protocol was used in an effort to obtain deep insights from the participants about the process of incorporation digital transformation into HRM practices. The findings indicate that PT Dirgantara Indonesia has made strategic and systematic efforts to develop the human resources based on digital technology. Some of the significant initiatives include digitization of business processes, application of digitally integrated databases, and innovation-driven product and service development. It has also introduced hundreds of digital training and empowerment programs, automated manual processes, and changed internal rules to adapt to shifting digital market realities. The organizational leaders applied the APS-6 INDI 4.0 Assessment to evaluate the readiness of the organization for digital transformation, implemented immediate actions in areas where gaps were identified, and showed a continued necessity for them to adapt to new technology that will sustain performance at all levels.

HRMARS - This study investigates the key internal factors influencing the performance of school cooperatives in Malaysia, particularly within the Federal Territory. The research, rooted in the Stakeholder Theory, examines how governance, leadership, and members’ participation influence both the operational outcomes of school cooperatives and their engagement with external stakeholders. It has been well understood that school cooperatives, while capable of nurturing entrepreneurial skills and democratic values among students, many still struggle with performance due to internal inefficiencies and weak stakeholder collaboration. A quantitative approach was employed, collecting data through structured online surveys targeting teachers and student board members of school cooperatives affiliated with a national cooperative federation in Malaysia. The results were analysed using descriptive statistics and multiple regression analysis. The findings confirmed that good governance, effective leadership, and active levels of member participation are found to enhance cooperative performance. Furthermore, the study finds that the involvement of external stakeholders (government bodies, parents, and cooperative associations) is not only an outcome of strong internal practices but also a contributing factor to performance itself. This research contributes new insights to the underexplored domain of school-based cooperatives in Malaysia. The results are of practical value for policymakers, cooperative leaders, and educators aiming to improve policies or governance models, leadership development, and stakeholder relationships within the cooperative ecosystem. By strengthening both internal mechanisms and external collaborations, school cooperatives can become resilient and impactful institutions supporting Malaysia’s broader educational and cooperative movements.

The French Optical Ground Station (FrOGS) [1] is developed, by a consortium of industries: Safran Data System, OGS Technologies, Bertin ALPAO, and Airbus Defence and Space, with the support of CNES.The article presents the final bi-static architecture of the station, composed of a focal plane assembly dedicated to reception (Rx FPA), at the Cassegrain focus of the received Optical Tube Assembly (Rx OTA) and the Tx/Rx FPA at the coudé focus of the Tx OTA. Each focal plan assembly is equipped with an Adaptive Optics system. FrOGS architecture is designed to be modular and scalable, in order to cope with various orbits and laser applications. The station is currently used for two Airbus/CNES demonstrations: bi-directional communications to a GEO optical terminal (the TELEO demonstration [2]) and LEO direct to earth data repatriation of Earth Observation satellites (the LASIN demonstration [3]).FrOGS started free space optical links with TELEO in 2024, a mono-static architecture was used, emission and reception being done using a single adaptive optics bench. The new Rx OA FPA at the Cassegrain focus was qualified in July 2025 on a horizontal link and first results were obtained with TELEO in the bi-static configuration.After the launch of CO3D constellation in July 2025, LASIN demonstrator enters in its qualification phase with FrOGS.FrOGS, as an OGS demonstrator, is a powerful tool to assess the performance of various optical architectures for GEO and LEO optical links, which allows to point to optimal configurations for future operational OGS..

Abstract The estimation of CME arrival time strongly depends on the CME propagation models in interplanetary space and the geometrical aspects of the CME model. We conducted ensemble simulations of CMEs propagation with various elliptical cone shapes to study the relation between the CME speed and the optimum cone shape. We numerically searched for the best elliptical aspect ratio of the elliptical cone for each CME in our CME-ICME pair data. We found that the fast CMEs tend to have a higher elliptical aspect ratio (more circular) than the slower CMEs (flattened). Our results suggest that a fast CME gives a stronger push to all directions, which results in a more circular shape of the leading-edge. We believe that this velocity-dependent behavior is related to the different Lorentz force strengths during the early expansion of a CME.

This article provides a detailed examination of structured packet scheduling methodologies in ground-based LoRa networks, with a special emphasis on Time Division Multiple Access (TDMA) techniques. As LoRa becomes an important enabler for long-range, low-power IoT deployments, managing packet collisions and energy efficiency in dense, multi-sensor node environments has become a crucial challenge, particularly in the ground segment of space-integrated IoT systems. Traditional ALOHA-based access methods have significant collision rates and unpredictable delays, highlighting the need for more deterministic and scalable scheduling algorithms. This paper examines current advances in TDMAbased frameworks, adaptive scheduling algorithms, and synchronisation approaches that aim to improve real-time data transfer from sensor nodes to ground gateways. Comparative analyses are carried out to assess techniques in terms of packet delivery ratio, latency, and energy performance, using data from both simulation-based research and prototype implementations. Furthermore, emergent research issues like AI-assisted scheduling, predictive synchronisation, and hardware testbeds are investigated as potential solutions to practical restrictions. By focusing solely on the ground segment, this study highlights the importance of intelligent, energyefficient TDMA scheduling for dependable packet aggregation in LoRa-based IoT networks. The findings are intended to direct future research into establishing strong, scalable communication frameworks for environmental monitoring, disaster management, and other vital remote sensing applications.
