Embedded Computation Architectures for Autonomy in Unmanned Aircraft Systems (UAS).

This paper addresses the challenge of embedded computing resources required by future autonomous Unmanned Aircraft Systems (UAS). Based on an analysis of the required onboard functions that will lead to higher levels of autonomy, we look at most common UAS tasks to first propose a classification of UAS tasks considering categories such as flight, navigation, safety, mission and executing entities such as human, offline machine, embedded system. We then analyse how a given combination of tasks can lead to higher levels of autonomy by defining an autonomy level.

Do high risk patients alter their lifestyle to reduce risk of colorectal cancer?

Background: Colorectal cancer (CRC) may be reduced by healthy lifestyle behaviours. We determined the extent of self-reported lifestyle changes in people at increased risk of CRC, and the association of these reports with anxiety, risk and knowledge-based variables.

Methods: We randomly selected 250 participants who had undergone surveillance colonoscopy for family history of CRC.

Perceived risks and benefits of surveillance colonoscopy in people undergoing surveillance for family history of colorectal cancer.

Aim: To determine perceived risks and benefits of colonoscopy surveillance among patients undergoing surveillance colonoscopy due to family history of colorectal cancer (CRC).

Method: We conducted a standardised phone interview of 250 randomly selected people who had undergone surveillance colonoscopy at Dunedin Hospital. We assessed perceptions of colonoscopy effectiveness, complication rates, and CRC risk.
