The Optimal Lattice Quantizer in Nine Dimensions [PDF]
AbstractThe optimal lattice quantizer is the lattice that minimizes the (dimensionless) second momentG. In dimensions 1 to 3, it has been proven that the optimal lattice quantizer is one of the classical lattices, and there is good numerical evidence for this in dimensions 4 to 8.

Optimal taxation with multiple dimensions of heterogeneity
This paper develops a general theory of optimal income taxation with multiple dimensions of agent heterogeneity. The main technical hurdle in developing this theory is the possibility that individuals have multiple optimal incomes. Using a perturbation approach, optimal tax formulas are derived that account for the possibility that individuals have ...

Optimization of Gyrotron Resonator’s Dimensions [PDF]
This paper explains the procedure of determining the initial dimensions of a gyrotron resonator. In particular, the paper discusses which geometrical parameters impact the wave properties of the resonator. The solution is implemented using Matlab software and estimations are performed with the use of the SMath Studio ...

Optimization of Invasive Weed for Optimal Dimensions of Concrete Gravity Dams [PDF]
Dam construction projects among the most extensive and most expensive projects are considered. It is always appropriate and optimal for such concrete structures to reduce the volume of concrete and consequently reduce construction costs is essential.

Statistical Optimization in High Dimensions [PDF]
We consider optimization problems whose parameters are known only approximately, based on noisy samples. In large-scale applications, the number of samples one can collect is typically of the same order of (or even less than) the dimensionality of the problem.

An approach to the optimization of thin-walled cantilever open section beams [PDF]
An approach to the optimization of the thin-walled cantilever open section beams subjected to the bending and to the constrained torsion is considered. The problem is reduced to the determination of minimum mass, i.e.

Gravity from thermodynamics: Optimal transport and negative effective dimensions
We prove an equivalence between the classical equations of motion governing vacuum gravity compactifications (and more general warped-product spacetimes) and a concavity property of entropy under time evolution.
