Optimal Crowdfunding Design [PDF]

open access: yesSSRN Electronic Journal, 2014
We characterize optimal reward-based crowdfunding where production is contingent on an aggregate funding threshold. Crowdfunding adapts project implementation to demand (market-testing) and its multiple prices enhance rent-extraction via pivotality, even for large crowds, indeed arbitrarily large if tastes are correlated.

Packing Oblique 3D Objects

open access: yesMathematics, 2020
Packing irregular 3D objects in a cuboid of minimum volume is considered. Each object is composed of a number of convex shapes, such as oblique and right circular cylinders, cones and truncated cones.

An Optimized Covering Spheroids by Spheres

open access: yesApplied Sciences, 2020
Covering spheroids (ellipsoids of revolution) by different spheres is studied. The research is motivated by packing non-spherical particles arising in natural sciences, e.g., in powder technologies.

Radial Gradient Pressure Effects on Flow Behavior in a Dual Volute Turbocharger Turbine

open access: yesApplied Sciences, 2018
The pressure gradient in the dual volute radial turbocharger turbines is the primary source of the vortices’ formation in rotor passages. The effects of the upstream non-uniform flow conditions on the development of secondary flows are not well known. In

Optimal design for additive partially nonlinear models [PDF]

open access: yes, 2010
We develop optimal design theory for additive partially nonlinear regression models, showing that Bayesian and standardized maximin D-optimal designs can be found as the products of the corresponding optimal designs in one dimension.

Discrete Mechanics and Optimal Control for Space Trajectory Design [PDF]

open access: yes, 2011
Space trajectory design is often achieved through a combination of dynamical systems theory and optimal control. The union of trajectory design techniques utilizing invariant manifolds of the planar circular restricted three-body problem and the optimal ...
