Currently, there exist a large number of superb digital libraries, all of which are, unfortunately, vertically integrated and all presenting a monolithic interface to their users. Ideally, a user would want to locate resources from a variety of digital libraries dealing only with one interface. A number of approaches exist to this interoperability issue exist including: defining a universal pro...

Example Consider a system consisting of several distributed objects implemented using CORBA. To access one of the distributed objects, a client typically needs to obtain a reference to the object. An object reference identifies the distributed object that will receive the request. Object references can be passed around in the system as parameters to operations as well as results of requests. A ...

Our goal is to promote the publication and standardization of digital objects stored on the web to enable model and object reuse. A digital object is an electronic representation of a physical object, including models of the object. There remain many challenges and issues regarding the representation and utilization of these objects, since it is not clear, for example, who will create certain o...

Within information systems, a significant aspect of search and retrieval across information objects, such as datasets, journal articles, or images, relies on the identity construction of the objects. This paper uses identity to refer to the qualities or characteristics of an information object that make it definable and recognizable, and can be used to distinguish it from other objects. Identit...

Fringe Pattern Profilometry (FPP) is 3D surface measuring technique based on triangulation. The utilization of digital projection in FPP system introduces significant phase distortion for Phase Shifting Profilometry (PSP), because of the nonlinear response of digital video projectors, which is referred as gamma distortion. Considering that the distorted phase has a stable function for a referen...

A digital fringe projection (DFP) system is developed to achieve non-intrusive thickness measurements of wind-driven water droplet/rivulet flows over a test plate to quantify the unsteady surface water transport process pertinent to various atmospheric icing phenomena. The DFP technique is based on the principle of structured light triangulation in a similar manner as a stereo vision system but...
