Compression and Coding of Large CAD Models

In this paper we introduce a compression scheme suitable for large CAD (Computer Aided Design) models. We assume as input a large model in IGES and VRML formats that encode e ciently and transmit to a client for remote display and modeling. To this end we focus on two main issues: (a) space e cient encoding of IGES and VRML les, (b) fragmentation of the compressed model into small independent u...

Single Resolution Compression of Arbitrary Triangular Meshes with Properties

Polygonal meshes have been used as the primary geometric model representation for networked gaming and for complex interactive design in manufacturing. Accurate polygonal mesh approximation of a surface with sharp features (holes, highly varying curvatures) requires extremely large number of triangles. Transmission of such large triangle meshes is critical to many applications that interactivel...

On Capacity of Non-Coherent Diamond NetworksThis work was supported in part by NSF grants 1514531 and 1314937

There is a vast body of work on the capacity bounds for a "coherent" wireless network, where the network channel gains are known, at least at the destination. However, there has been much less attention to the case where the network parameters (channel gains) are unknown to everyone, i.e., the non-coherent wireless network capacity. In this paper, we study the generalized degrees of freedom (gD...

Using curriculum vitae to compare some impacts of NSF research grants with research Center funding

While traditional grants remain central in US federal support of academic scientists and engineers, the role of multidisciplinary NSF Centers is growing. Little is known about how funding through these Centers affects scientific output or (as is an NSF aim) increases academic collaboration with industry. This paper tests the use of CVs to examine how Center funding affects researchers’ publicat...
