The space sector is currently undergoing a transformative phase marked by the emergence of CubeSat projects. Although many CubeSats are launched annually, only a few manage to accomplish their missions. This challenge is partly attributed to the inherent complexity of CubeSats, which, despite their small size, remain intricate systems. Companies engaged in CubeSat development generally lack the resources and regulatory impetus to implement systematic engineering processes, as outlined in international standards. The absence of a straightforward and space-specific systemengineering framework hinders teams in effectively managing their development processes, addressing system complexity, and consequently, limits the success rate of missions. The objective of this article is to delineate the methodology devised to formulate such a framework. Our approach is anchored in the utilization of the ISO/IEC TR 29110-1:2016 systemengineering standard, which we propose to expand to align with the specifications of the space sector defined in the ECSS-EST- 10C standard. The deployment of an initial version of the framework in a project undertaken by the Expleo Group, along with parallel initiatives within the European Space Agency, serves as a catalyst for further exploration in this direction.

Nowadays, automation software systems play a crucial role in assisting humans with specific tasks, particularly in online communication for timely interactions. However, the misuse of such systems poses risks, impacting website performance, leading to data access violations, or even posing threats to the system's security. To address these challenges, an automatic software inspection system has been developed as a prototype, aimed at preventing potential issues in the online domain. Machine learning algorithms are employed to enhance detection accuracy, with the decision tree algorithm demonstrating a maximum accuracy of 97.4%. This promising result suggests its suitability for further development into a JavaScript library, offering a valuable resource for future website applications.

Though technological advancements bring convenience to humans, they also pose environmental damage. EVs are an alternative that tackles these concerns. However, the growing popularity of EVs is starting to cause problems in distribution systems, especially when the uncoordinated charging of EVs in each house risks overloading distribution transformers. This paper proposes efficient strategies for managing EV chargers in houses. In the event of transformer overload, the proposed control system will control the EV chargers of each house to decrease the power output. However, consumers have an option to pay an additional fee to retain the privilege of charging their EVs without any reduction in power output. Consumers who do not pay an additional fee will experience a proportional reduction in power output. This strategy provides an option for consumers who require charging urgently. To test the effectiveness of the proposed method, this paper utilized two test systems. The first test system is a seven-bus system featuring a 100-kVA distribution transformer, and the second test system is an ieee European LV feeder featuring a 500-kVA distribution transformer. Test results indicate that the proposed strategy can prevent overload of distribution transformers. This approach helps alleviate concerns about the increasing demand for EV charging in numerous houses during peak usage times.

The automotive industry is undergoing rapid growth driven by advancements such as electrification, necessitating efficient software development methodologies. While model-based systemengineering is prevalent in automotive software development, its application is typically confined to the requirements and design phases, with manual coding still dominating the development process, resulting in extended development efforts and cycles. To address these challenges, we propose Vehicle Domain-Specific Language (VDSL), a low-code development tool that integrates modeling and automatic code generation. With VDSL, users can simply specify their requirements and utilize graphical drag-and-drop along with parameter configuration to efficiently implement vehicle functionality with auto-generated code. Tested and evaluated on 3 vehicle models across 18 months at GAC Group, VDSL has demonstrated its effectiveness in significantly reducing development effort and costs, improving resource efficiency, and providing greater flexibility for system updates via Over-The-Air (OTA) technology. This work further enhances the practicality of model-based development in the automotive domain, boosting development efficiency and potentially enhancing quality.
