In this study, the challenges and solutions related to the simultaneous submission of a manuscript to more than one journal were investigated. Always, the found challenges exist and occur consciously or unconsciously. Unfortunately, an applicable solution has not been offered in this regard so far. I have introduced a new way, for the first time, that provides all publishers with a controllable submission process. The provided solution is an application programming interface that is linked to a central database and could save critical information of all submitted manuscripts such as title, authors' information, abstract, keywords, date of first submission and history of referee's comments. All publishers throughout the world can join this database, enable its advanced features for their journals and try to providing a controllable submission system against this important publishing challenge.

This paper focuses on drag estimation in cruise flight for civil supersonic aircraft. A comparison of simple conceptual design methods applied to several reference aircraft shows relatively large differences in drag estimation. For this reason, another approach is needed. Therefore, the buildup of an aerodynamic surrogate model based on Reynolds-averaged Navier-Stokes (RANS) simulations is performed. In detail, the process chain including CAD model generation, mesh generation and computational flow simulation (CFD) with the DLR TAU code is described. Furthermore, the integration of the process chain into the DLR "Surrogate Modeling for AeRo Data Toolbox Python Package" (SMARTy) is presented. With the help of SMARTy, an aerodynamic surrogate model is created. In the end, an example optimization is performed and analyzed based on a Concorde-like wing-fuselage geometry.

When a new requirement emerges for an existing application programming interface (API) there are several decisions to make. Most of these decisions are difficult to change later when many stakeholders are involved. This means that bad decisions can create a lot of complications and thus effort. First it needs to be decided whether to modify an existing operation, e.g. an API endpoint, grow it or rather create a new operation from scratch. When designing a FRESH OPERATION there are many possibilities and decisions to make. This offers a variety of pitfalls. One option to avoid them is to create a CLOSE RELATIVE. This means that rather than incorporating as many innovations as possible the existing API landscape is carefully examined for aspects and decisions that are worth to be reused. These are then incorporated into the new operation. This paper presents the two patterns FRESH OPERATION and CLOSE RELATIVE and shows their relation to neighboring patterns.

Model-Based Systems Engineering (MBSE) has been increasingly embraced by both industry and government to keep track of system complexity. MBSE allows the engineer to represent the system in a comprehensive computer model, allowing for better traceability, tracking, and information consistency. The vision and promise of MBSE is one where systems models and analyses are tightly integrated in an automated, collaborative, easily accessible, and secure framework. However, the current state-of-the-art falls short of this promise due to a significant gap between MBSE tools and their integration with analysis tools. Phoenix Integration proposes to develop and prototype a framework that would help realize the vision and promise of MBSE. This prototype framework will be web-based and will use existing tools and frameworks already deployed and being used by industry. This will be done by leveraging available existing technology as well as commercial products currently under development. At the center of the framework is the connection between No Magic Teamwork Cloud Server and ModelCenter (R) MBSE. Teamwork Cloud Server is a web-based MBSE collaboration platform, while ModelCenter (R) MBSE is a next generation MBSE analysis integration tool currently being commercially developed at Phoenix Integration. This framework will be connected to distributed or high-performance computing resources for quick analysis execution, as well as a continuous integration server for automated execution in response to a model change. In addition to being able to interact with the systems model through a web environment, the user would be able to execute the associated analyses and workflows using information from the systems model. Automatic requirements verification can be performed through automated analysis execution whenever a change in the systems model is detected. Results can be displayed on a web-enabled dashboard, together with interactive charts and plots to help visualize results and d

As part of its manufacturing initiative, TEAM is actively involved in open architecture controller activities. Within the TEAM community of members, TEAM is developing an open architecture controller requirements document and an open architecture controller application programming interface document. In addition, TEAM is also evaluating early open architecture controllers in a shop floor environment.

Two fully automated Python- and MATLAB-HFSS interfaces without VBA scripts are presented. They are automated since to run they require only the HFSS file describing the model and either the Python or MATLAB scripts of the APIs. All the auxiliary files are generated directly by the APIs. As an example, the findings are applied to the design of the external quality factor in microwave cavity filters.

This paper presents the lessons learned from the data analysis of simulations of Urban Air Mobility (UAM) operations that will be used to provide recommendations for future UAM system architecture and airspace services improvements. In support of the gradual maturation of the UAM industry, NASA has been conducting a series of UAM air traffic simulations. With industry partners for UAM airspace services, NASA recently completed collaborative simulations - collectively referred to as X4 - focusing on strategic conflict management. The architecture of the simulation system includes various software modules that were independently developed and integrated to provide airspace services to UAM operators. A detailed analysis of the data collected during simulations was conducted to support performance assessment of the X4 system architecture. This paper describes the results of the data analysis including metrics such as throughput at various resources, the detection and resolution of simulated demand-capacity imbalances using pre-departure delays, and conformance of operations to their operational intents.
