An algorithm for two-dimensional mesh generation based on the pinwheel tiling
, 2004 We propose a new two-dimensional meshing algorithm called PINW able to generate meshes that accurately approximate the distance between any two domain points by paths composed only of cell edges.

Optimal Deployments of UAVs With Directional Antennas for a Power-Efficient Coverage [PDF]
, 2019 To provide a reliable wireless uplink for users in a given ground area, one can deploy Unmanned Aerial Vehicles (UAVs) as base stations (BSs). In another application, one can use UAVs to collect data from sensors on the ground.

A Fatou theorem for $F$-harmonic functions
, 2016 In this paper we study a class of functions that appear naturally in some equidistribution problems and that we call $F$-harmonic. These are functions of the universal cover of a closed and negatively curved which possess an integral representation ...

Attitude and Orbital Dynamics of a Variable-Geometry, Spinning Solar Sail in Earth Orbit [PDF]
, 2017 At the ISSS 2013, a novel concept of variable-geometry solar sail was introduced: deployed in the shape of a three-dimensional quasi-rhombic pyramid (QRP), the sail exploited its shape and shift between center of mass and center of pressure to naturally ...

Tilings of an Isosceles Triangle
, 2019 An N-tiling of triangle ABC by triangle T is a way of writing ABC as a union of N trianglescongruent to T, overlapping only at their boundaries. The triangle T is the "tile". The tile may or may not be similar to ABC.

An assessment of the impact of water impoundment and diversion structures on vegetation in Southern Arizona [PDF]
High-altitude color infrared photography was used to survey existing conditions, both upstream and downstream, from nineteen diversion structures in Southern Arizona to determine their effect upon vegetation health, vigor, and cover.
