The paper is a preliminary report on the design of a framework, called Dv, for building interactive distributed visualizations on computational grids. The framework is based on a form of mobile object, called an active frame, that consists of applicationdata and a program that manipulates the data. The system provides a flexible framework for building distributed applications that are performan...

This paper presents an expert system ESSCAD developed for integrating construction scheduling with CAD drawing. The system, which was developed mainly with knowledge-based system programming technique and software integrating technique, can automatically interpret the CAD drawings of a building and extract data of its building components, breakdown the project into activities, determine the log...

We present a mobile augmented reality (AR) system to guide a user through an unfamiliar building to a destination room. The system presents a world-registered wire frame model of the building labeled with directional information in a see-through heads-up display, and a three-dimensional world-in-miniature (WIM) map on a wrist-worn pad that also acts as an input device. Tracking is done using a ...

The poor performance of wood light-frame construction (WLFC) during recent hurricanes disputed the efficacy of the wood light-frame building process in high wind environments. Deficiencies observed in the wake of Hurricane Andrew (1992) in particular suggest that solutions to the problem must consider human-based factors within the building process. The objective of this thesis is to develop an...

Masonry infill walls are often used as non-structural elements. According to the past structural failure, ignorance of interaction between infill walls and enclosed frame may lead to the different seismic response for non-ductile building frames. The main contribution of this paper is to analytically investigate the behavior of reinforced concrete with masonry infill panels as participating str...

A dual structural fused system consists of replaceable ductile elements (fuses) that sustain major seismic damage and leave the primary structure (PS) virtually undamaged. The seismic performance of a fused structural system is determined by the combined behavior of the individual PS and fuse components. In order to design a feasible and economic structural fuse concept, we need a procedure to ...

essence of the frame theory: When one encounters a new situation (or makes a substantial change tn one's view of a problem), one selects from memory a structure called a frame. This is a remembered framework to be adapted to fit reality by changing details as necessary. A frame is a data-structure for representing a stereotyped situation like being in a certain kind of living room or going to a...

The notion of $k$-frames was recently introduced by Gu avruc ta in Hilbert  spaces to study atomic systems with respect to a bounded linear operator. A continuous frame is a family of vectors in a Hilbert space which allows reproductions of arbitrary elements by continuous super positions. In this manuscript, we construct a continuous $k$-frame, so called c$k$-frame along with an atomic system ...

Realistic-looking architectural models with furniture may consist of millions of polygons and require gigabytes of data { far more than today's workstations can render at interactive frame rates or store in physical memory. We have developed data structures and algorithms for identifying a small portion of a large model to load into memory and render during each frame of an interactive walkthro...
