Conceptual design proposal for the EU-DEMO electron cyclotron ex-vessel waveguide system with enhanced remote maintainability

This paper presents an internet‐based decision support system (DSS) conceptual proposal for the appraisal stage of healthcare construction projects. The underlying philosophy of the approach is to integrate architectural space programming and costestimating processes with a risk assessment approach in order to obtain a more accurate inception cost estimate of the healthcare project along with its preliminary space program outline. The system’s main objectives focus on assisting decision makers in the United Arab Emirates in examining different space program alternatives with their associated capital budgets. In addition, the system will assist in reflecting associated risk factors and affecting budget approval decisions in their inception stage. The Internet is utilized as a mechanism for communicating and updating project data and cost information. This paper describes a conceptual design proposal for the system and the proposed strategy for its design and construction.

The following paper has the purpose of presenting an innovative solution for building facade cleaning using an unmanned aerial vehicle (UAV) that employs pressure washing technique and hydrogen fuel cell (HFC) technology to enhance flight autonomy. Indeed, the main design stages are both stated and explained within the paper. However, the design is separated in two stages: Conceptual and Preliminary. Thus, it begins with the research statement, state of the art revision and conceptual design proposal. Then, it continues with the development of the propulsion system, which uses a proposed recursive methodology for estimating, selecting, and then confirming all the inter-dependent elements such as motors, propellers, fuel cell and hydrogen amount. As the drone is treated as a mechatronic machine, the following design explores certain domains that help build it, such as: Mechanical, Electrical and Control. The Mechanical domain emphasizes on frame design, material selection, resistance calculations, pressure washing gun recoil analysis, and finite element and aerodynamic simulations. The Electrical domain focuses on component selection and power consumption verification while the last domain proposes flow diagrams and a PID control diagram based on an hexacopter mathematical modelling. Finally, the main flight parameters are simulated on SIMULINK, obtaining appropriate stabilizing and response times according to limitations cited.
