    Good situation awareness is one of the key attributes required to maintain safe flight, especially for an Unmanned Aerial System (UAS). Good situation awareness can be achieved by incorporating an Adaptive Health Monitoring System (AHMS) to the aircraft. The AHMS monitors the flight outcome or flight behaviours of the aircraft based on its external environmental conditions and the behaviour of its internal systems. The AHMS does this by associating a health value to the aircraft's behaviour based on the progression of its sensory values produced by the aircraft's modules, components and/or subsystems. The AHMS indicates erroneous flight behaviour when a deviation to this health information is produced. This will be useful for a UAS because the pilot is taken out of the control loop and is unaware of how the environment and/or faults are affecting the behaviour of the aircraft. The autonomous pilot can use this health information to help produce safer and securer flight behaviour or fault tolerance to the aircraft. This allows the aircraft to fly safely in whatever the environmental conditions. This health information can also be used to help increase the endurance of the aircraft. This paper describes how the AHMS performs its capabilities

    Securing intellectual capital:an exploratory study in Australian universities

    Purpose – To investigate the links between IC and the protection of data, information and knowledge in universities, as organizations with unique knowledge-related foci and challenges.Design/methodology/approach – We gathered insights from existing IC-related research publications to delineate key foundational aspects of IC, identify and propose links to traditional information security that impact the protection of IC. We conducted interviews with key stakeholders in Australian universities in order to validate these links.Findings – Our investigation revealed two kinds of embeddedness characterizing the organizational fabric of universities: (1) vertical and (2) horizontal, with an emphasis on the connection between these and IC-related knowledge protection within these institutions.Research implications – There is a need to acknowledge the different roles played by actors within the university, and the relevance of information security to IC-related preservation.Practical implications – Framing information security as an IC-related issue can help IT security managers communicate the need for knowledge security with executives in higher education, and secure funding to preserve and secure such IC-related knowledge, once its value is recognized.Originality/value – This is one of the first studies to explore the connections between data and information security and the three core components of IC’s knowledge security in the university context

    The findings from the California Indian Culture and Sovereignty Center's 2012 report confirmed the need for greater efforts to prepare, to recruit, to retain, and to graduate Native youth from institutions of higher education. In particular, the realization that AI/AN enrollment rates are declining across the CSUs was alarming. These results provided the basis to delve deeper into the program, outreach, and support of postsecondary institutions in the 2014 report to determine where enrollment and transfer numbers are decreasing or increasing; to determine what the best practices at state colleges and universities to attract, retain, and graduate AI/ANs are; and correspondingly to determine where we, as educators of AI/AN students in the state of California, need to improve
