Asymmetric Multilevel Diversity Coding and Asymmetric Gaussian Multiple Descriptions

Suhas Diggavi

We consider the asymmetric multilevel diversity (A-MLD) coding problem, where a set of 2(K) - 1 information sources, ordered in a decreasing level of importance, is encoded into K messages (or descriptions). There are 2(K) - 1 decoders, each of which has a ...

Asymmetric Gaussian Multiple Descriptions and Asymmetric Multilevel Diversity Coding

Suhas Diggavi

We consider multiple description source coding problem with Gaussian source and mean squared error, for

K=3

descriptions. We obtain an outer bound for the rate region of the problem. We also derive an inner bound for the problem based on successively ref ...

Multiscale modeling in advanced materials research: Challenges, novel methods, and emerging applications

William Curtin

The concept of multiscale modeling embodies the idea that a comprehensive description of a material will require an understanding over multiple time and length scales. A multiscale model requires that descriptions at all levels be consistent with each othe ...

Object manipulation and grasping for virtual humans

Tolga Abaci

Virtual environments need virtual humans that are capable of interacting with objects around them. Existing virtual environments have not found satisfactory general solutions for this problem. The common method is to combine pre-designed (or motion capture ...

An object-oriented model for adaptive high-performance computing on the computational GRID

Tuan Anh Nguyen

The dissertation presents a new parallel programming paradigm for developing high performance (HPC) applications on the Grid. We address the question "How to tailor HPC applications to the Grid?" where the heterogeneity and the large scale of resources are ...

Foundations of systems and properties

Otto Preiss

Engineering of software-intensive systems is concerned with the creation and evolution of systems that shall exhibit desired properties in their execution as well as development environment. In this context, the motivation of this thesis, derived from curr ...

Specifying reactive system behavior

Shane Sendall

Fundamentally, the development of software applications involves dealing with two distinct domains: the real world and software domains; the two converge at the point where a software application is used to make an unsatisfactory real world situation into ...

Using OCL and UML to Specify System Behavior

Shane Sendall

Use cases are an excellent tool for capturing behavioral requirements of software systems, but they are not an ideal work product for driving design activities. We believe that there is value from complementing use case descriptions with pre- and postcondi ...

From Use Cases to System Operation Specifications

Shane Sendall

The purpose of this paper is to first showcase the concept of an operation schema - a precise form of system-level operation specification and secondly show how operation schemas enhance development when they are used as a supplement to use case descriptio ...

Analysis of PROTEUS phase II experiments in support of light water high conversion reactor design

Rakesh Chawla

Fourteen test zones were studied in the Phase II program of light water high conversion reactor physics experiments at the PROTEUS zero-power facility in Wurenlingen. The test lattice configurations investigated, the types of integral measurements carried ...
