111	THE CRIMINALISATION OF NGO-LED SAR OPERATIONS : A Contributing Factor Towards Crimes Against Humanity Against Migrants in Libya Kaur, Maanpreet January 2023 (has links) In the perilous waters of the Mediterranean Sea, migrants find themselves facing limited choices when in distress. Their options are stark: either to rely on the lifesaving efforts of Non- Governmental Organisations (NGO) aid workers conducting Search and Rescue (SAR) Operations, to be intercepted by the Libyan Coast Guard (LCG) and subsequently detained in Libya where their human rights are gravely violated, or to face the tragic fate of perishing at sea. Unfortunately, the criminalisation of SAR Operations, spearheaded by NGO aid workers, hinders the rescue of migrants, thereby exacerbating the risks they face and leaving them vulnerable to interception by the LCG. This interception, as argued in this thesis, inevitably leads to the perpetration of Crimes Against Humanity (CAH) against these vulnerable migrants. This thesis sheds light on the issue of Italy’s increasing criminalisation and vilification of humanitarian aid workers engaged in SAR missions in the Mediterranean Sea. It critically examines the consequences of such criminalisation on the lives and rights of migrants, exploring the complex dynamics between SAR Operations, interception by the LCG, and the commission of CAH. Drawing upon a comprehensive lens of interpretation that integrates legal analysis, human rights principles, and the international legal framework, this study concludes that criminalisation of SAR operations is indeed a contributing factor towards the CAH faced by migrants in Libya. Moreover, it identifies the potential liability of Italian State Officials (ISO) at the International Criminal Court (ICC) for their role in enacting legislations that effectively criminalises SAR operations.

112	Asynchronous Event-Feature Detection and Tracking for SLAM Initialization Ta, Tai January 2024 (has links) Traditional cameras are most commonly used in visual SLAM to provide visual information about the scene and positional information about the camera motion. However, in the presence of varying illumination and rapid camera movement, the visual quality captured by traditional cameras diminishes. This limits the applicability of visual SLAM in challenging environments such as search and rescue situations. The emerging event camera has been shown to overcome the limitations of the traditional camera with the event camera's superior temporal resolution and wider dynamic range, opening up new areas of applications and research for event-based SLAM. In this thesis, several asynchronous feature detectors and trackers will be used to initialize SLAM using event camera data. To assess the pose estimation accuracy between the different feature detectors and trackers, the initialization performance was evaluated from datasets captured from various environments. Furthermore, two different methods to align corner-events were evaluated on the datasets to assess the difference. Results show that besides some slight variation in the number of accepted initializations, the alignment methods show no overall difference in any metric. Overall highest performance among the event-based trackers for initialization is HASTE with mostly high pose accuracy and a high number of accepted initializations. However, the performance degrades in featureless scenes. CET on the other hand shows mostly lower performance compared to HASTE.

113	A plm implementation for aerospace systems engineering-conceptual rotorcraft design Hart, Peter Bartholomew 08 April 2009 (has links) The thesis will discuss the Systems Engineering phase of an original Conceptual Design Engineering Methodology for Aerospace Engineering-Vehicle Synthesis. This iterative phase is shown to benefit from digitization of Integrated Product&Process Design (IPPD) activities, through the application of Product Lifecycle Management (PLM) technologies. Requirements analysis through the use of Quality Function Deployment (QFD) and 7 MaP tools is explored as an illustration. A "Requirements Data Manager" (RDM) is used to show the ability to reduce the time and cost to design for both new and legacy/derivative designs. Here the COTS tool Teamcenter Systems Engineering (TCSE) is used as the RDM. The utility of the new methodology is explored through consideration of a legacy RFP based vehicle design proposal and associated aerospace engineering. The 2001 American Helicopter Society (AHS) 18th Student Design Competition RFP is considered as a starting point for the Systems Engineering phase. A Conceptual Design Engineering activity was conducted in 2000/2001 by Graduate students (including the author) in Rotorcraft Engineering at the Daniel Guggenheim School of Aerospace Engineering at the Georgia Institute of Technology, Atlanta GA. This resulted in the "Kingfisher" vehicle design, an advanced search and rescue rotorcraft capable of performing the "Perfect Storm" mission, from the movie of the same name. The associated requirements, architectures, and work breakdown structure data sets for the Kingfisher are used to relate the capabilities of the proposed Integrated Digital Environment (IDE). The IDE is discussed as a repository for legacy knowledge capture, management, and design template creation. A primary thesis theme is to promote the automation of the up-front conceptual definition of complex systems, specifically aerospace vehicles, while anticipating downstream preliminary and full spectrum lifecycle design activities. The thesis forms a basis for additional discussions of PLM tool integration across the engineering, manufacturing, MRO and EOL lifecycle phases to support business management processes.
