Energy complexity of optical computations
This paper provides lower bounds on the energy consumption and demonstrates an energy-time trade-off in optical computations. All the lower bounds are shown to have the matching u...

Computationally and Algebraically Complex Finite Algebra Membership Problems
In this paper we produce a finite algebra which generates a variety with a PSPACE-complete membership problem. We produce another finite algebra with a γ function that grows exp...

The Persistent Morse Complex Segmentation of a 3-Manifold
We describe an algorithm for segmenting three-dimensional medical imaging data modeled as a continuous function on a 3-manifold. It is related to watershed algorithms developed in ...

Surface Reflectance Modeling of Real Objects with Interreflections
In mixed reality, especially in augmented virtuality which virtualizes real objects, it is important to estimate object surface reflectance properties to render the objects under ...
