Flight MTT-S 2020: Cleared for Takeoff

Flight Safety Assessment and Management during Takeoff

The goal of a safety management system is to monitor sensors, identify hazards and mitigate risk to the extent possible. In this paper, we present a novel approach called Flight Safety Assessment and Management (FSAM) to assess key quantitative and qualitative feedback parameters for loss of control (LOC) risk. Decision making logic is specified as a set of hierarchical timed automata models. L...

Microsoft Word - A Body Reorientation Strategy in Insect Takeoff Flight

Fast and efficient recovery of flight orientation during takeoff or after a severe disturbance is desirable for micro flapping fliers. Navigating body through desired path in limited space and time needs fast and accurate control mechanisms to modulate flight moments. In this work we shot high-speed videos from dragonflies taking off starting from various initial orientations. Modifying equatio...

Reduction of MTT by glutathione S-transferase.

The reduction of the tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) to a blue formazan product is widely used for assaying cell survival and proliferation. The reduction reaction is catalyzed by dehydrogenases localized in the mitochondria of viable cells. As part of an analysis of the ability of glutathione S-transferase (GST) enzymes to protect cells from...
