This paper proposes a modeling of the energy consumption of a class of small convertible VTOL-UAVs (Vertical Take-Off and Landing Unmanned Aerial Vehicles). We consider systems composed of a set of coplanar propellers for propulsion and wing(s) to improve energy efficiency. Aerodynamics of propellers is modeled from standard momentum and blade element theories. In order to obtain simple closed-...
Type 1 diabetes involves both T helper (Th)1 and Th17 cells. While the mechanisms underlying the control of Th1 cells are relatively well defined, those operating modulation of Th17 cells remain unknown. Moreover, given that Th17 cells are plastic and can drive disease as stable or convertible T cells, effective approaches to counter type 1 diabetes would have to alter Th17 function under both ...
The theme of this paper is how to find all instances of a given “sample” graph in a larger “data graph,” using a single round of map-reduce. For the simplest sample graph, the triangle, we improve upon the best known such algorithm. We then examine the general case, considering both the communication cost between mappers and reducers and the total computation cost at the reducers. To minimize c...
