Scan paths are commonly used in digital design to improve the testability of sequential circuits since a full scan path provides complete controllability and observability for every bistable element. A traditional scan path is implemented after the circuit has been designed, with little regard to the actual circuit function. High-level synthesis can exploit knowledge of the circuit function to ...

A watershed based on rainfall simulation is a proven technique for image segmentation. The only problem associated with it is the path regularization for pixels in the plateau. As the existing methods employ sequential techniques, the complexity of the algorithms remains high due to repetitive scanning of pixels. We propose an iterative method for finding the shortest and steepest path based on...

This paper treats a high-level, algebraic programming method for the on-line control of actions in a realtime, parallel processing environment. The method is based on interaction of path expressions. On the basis of a set of path expressions evocation of actions can be controlled in realtime in a fully automated way. It is shown how intelligent system behaviour can be obtained by a combination ...

Color induced texture analysis is explored, using two texture analysis techniques: the co-occurrence matrix and the color correlogram as well as color histograms. Several quantization schemes for six color spaces and the humanbased 11 color quantization scheme have been applied. The VisTex texture database was used as test bed. A new color induced texture analysis approach is introduced: the pa...

This report includes all the technical details of the Sequential Principal Curves Analysis (SPCA) in a single document. SPCA is an unsupervised nonlinear and invertible feature extraction technique. The identified curvilinear features can be interpreted as a set of nonlinear sensors: the response of each sensor is the projection onto the corresponding feature. Moreover, it can be easily tuned f...

For oversized cargo transportation, traditional transportation schemes only consider road length, road width, the transportation cost as weight values in analysis and calculation of route selection. However, for oversized trucks, turning direction at road intersections is also a factor worth considering. By introducing the classical algorithm of Dijkstra into the model of road network, this res...

this study evaluates the discriminative power of sequential spectrum analysis of the short-term electrocardiogram (ecg) time series in separating normal and subjects with life threatening arrhythmias like, ventricular tachycardia/fibrillation (vt/vf). the raw ecg time series is transformed into a series of binary symbols and the binary occupancy or relative distribution of mono-sequences (i.e. ...

The problem of setting Open Shortest Path First (OSPF) weights on links such that congestion can be avoided is proved to be NP-hard. Many iterative heuristics have been applied to solve the OSPF weight setting (OSPFWS) problem. As the size of any combinatorial optimization problem increases, it becomes more difficult to find an optimum solution using sequential algorithms. In this paper, we inv...

Test pattern storage is an important problem aaect-ing all Design for Testability (DfT) techniques based on scan-path. Built-In Self Test (BIST) methodologies are used in conjunction to scan-path techniques for reducing the amount of test patterns that must be stored. This paper analyzes two SCAN/BIST approaches and identiies conditions which guarantee that such techniques require shorter test ...
