The problem of how to manage uncertainties when modeling or designing an engineering structure is briefly addressed here. Uncertainties may be relevant in the case of real structures, due to intrinsic variability of mechanical and physical properties as well as to the lack of knowledge when information are scarce and/or subject to some errors, for instance related to the test procedure. It is s...
This paper presents a new hybrid scheme for image data compression using quadtree decomposition and parametric line fitting. In the first phase of encoding, the input image is partitioned into quadrants using quadtree decomposition. To prevent from very small quadrants, a constraint of minimal block size is imposed during quadtree decomposition. Homogeneous quadrants are separated from non-homo...
Previous research has usually assumed that shopping on-line is a goal-oriented activity and is motivated by extrinsic factors of the customers. On the other hand, intrinsic factors, such as entertainment, have been found to be a major reason for peoples to use the Internet. This study examined whether such intrinsic motivations can be used to explain consumers’ acceptance of on-line shopping. A...
The use of an alphabet of line segments to compose a curve is a possible approach for curve data compression. Curves having more sophisticated topology with self-intersections can be handled by methods considering recursive decomposition of the canvas containing the curve. We propose a graph theory based algorithm for tracing the curve directly to eliminate the decomposition needs. This approac...
We present a methodology of an on-line variable-length binary encoding of a set of integers. The basic principle of this methodology is to maintain the preex property amongst the codes assigned on-line to a set of integers growing dynamically. The preex property enables unique decoding of a string of elements from this set. To show the utility of this on-line variable length binary encoding, we...

With the widening gap between processor and memory speeds, memory system designers may find cache compression beneficial to increase cache capacity and reduce off-chip bandwidth. Most hardware compression algorithms fall into the dictionary-based category, which depend on building a dictionary and using its entries to encode repeated data values. Such algorithms are effective in compressing lar...
Somatosensory evoked potentials (SEPs) waveform recorded from the normal and injured spinal cord in rats were analyzed. A mild compression spinal cord injury was performed in two experimental models. The first model was used to assess the disappearance and the second one the return of the electrophysiological spinal cord function after injury. In the first experimental model typical changes in ...
We develop a volumetric video system which supports interactive browsing of compressed time-varying volumetric features (significant isosurfaces and interval volumes). Since the size of even one volumetric frame in a time-varying 3D data set is very large, transmission and on-line reconstruction are the main bottlenecks for interactive remote visualization of time-varying volume and surface dat...
