Detailed knowledge of a circuit’s timing is essential for performance optimization, timing closure, and generation of test patterns to detect small-delay defects. When an input transition is applied to the circuit’s inputs, the resulting delay is not only determined by the propagation path, but also influenced by the power-supply noise. We introduce a path-sensitization procedure which precisely controls...
Large-scale self-organised systems, such as distributed community energy systems, have called for coordination approaches that are able to deal with issues such as heterogeneity, inter-dependence and dynamic variability. Holonic institutions have been proposed as an approach to converging the structuration required for multi-scale, multi-criteria optimisation in nested enterprises with the formal...
We present a versatile method that enumerates all or a user-specified number of longest sensitisable paths in the whole circuit or through specific components. The path information can be used for design and test of circuits affected by statistical process variations. The algorithm encodes all aspects of the path search as an instance of the Boolean Satisfiability Problem (SAT), which allows the method...
The competition of supply chain has become the main form of the enterprise competition. But the complexity of the supply chain network improves the difficulty of enterprise management of supply chain. The monitoring taking a single supplier as the object cannot fully and truly reflect the suppliers' ability to provide products and service. The sub-chain is the local link of supply chain and supply...
With the Simplification of development environment, the code works is getting easier and easier. However, coders pay less attention to make their software better. With the time pass by, database will become larger and larger, typical problem followed is that applications run more and more slowly, and eventually, exceed the limit of users' patience. Lacking of necessary optimization is one of the most...
This paper presents an improved algorithm for reactive power compensation. The objectives is to minimized the power loss and the compensation cost and the percentage of overvoltage. Operation variables include the generator's active power and reactive power output, the transformer tap, capacitor's and reactance's units. This research attempts to solve a complicated nonlinear mixed planning problem...
