QoS routing involves selection of paths for flows based on the knowledge at network nodes about the availability of resources along paths, and the QoS requirements of flows. Several QoS routing schemes have been proposed that differ in the way they gather information about the network state and select paths using this information. Most of these schemes can be categorized as best path routing wh...

A new approach to the refixturing-free sculpturing of large, arbitrarily complex shapes has been developed. Based on an enhanced accessibility analysis of the target shape, a reduced set of candidate machining orientations is determined. Then, machining takes place at very close distance between the tooling machinery and the part, thus achieving effective material removal in complex regions. Mi...

A high-speed interrogation scheme for large-scale fiber Bragg grating (FBG) sensing arrays is presented. This technique employs parallel computing and pipeline control to modulate incident light and demodulate the reflected sensing signal. One Electro-optic modulator (EOM) and one semiconductor optical amplifier (SOA) were used to generate a phase delay to filter reflected spectrum form multipl...

We present a methodology for the automated selection and aggregation of (Web) services with the purpose of satisfying client queries. A key ingredient of our approach is the notion of service contract, which consists of signature (WSDL), ontology information (OWL), and behaviour specification (YAWL). The methodology inputs a registry of service contracts and a client service contract, and it au...

In the developed countries, especially over the last decade, there has been an explosive growth in the capability to generate, collect and use very large data sets. The objects of these data sets could be simultaneously described by quantitative and qualitative attributes. At present, algorithms able to process either very large data sets (in metric spaces) or mixed (qualitative and quantitativ...

A new approach for using path analysis to appraise the verisimilitude of theories is described. Rather than trying to test a model's truth (correctness), this method corroborates a class of path diagrams by determining how well they predict intradata relations in comparison with other diagrams. The observed correlation matrix is partitioned into disjoint sets. One set is used to estimate the mo...

To optimize the functional space layout of various transportation modes integrated passenger transport hub, and improve transfer efficiency service quality a quantitative analysis flow lines hub is carried out. The research clarifies factors areas “get on drop off areas” for each mode transportation, generates candidate set placement area, determines priority ranking sets starting end locations...
