This paper concerns the endpoint estimation of the basic oxygen furnace (BOF) steel making process. More specifically, a back propagation (BP) neural network is employed to estimate the endpoint carbon content and the endpoint temperature of BOF, and an improved particle swarm optimization (PSO) algorithm is proposed to optimize the prediction model for improving the accuracy of the endpoint pr...

Refer to Figure 1. A monotone matching is a set of n segments, each the portion of a unique pseudoline, and each spanning a unique slab, such that the left endpoint of each segment is above the right endpoint of the segment in the previous slab. In addition, the point on the first vertical line is below the left endpoint of the first segment, and the point on the last vertical line is above the...

However, if one averages the solution in L in the angular variable, we show that the homogeneous endpoint and the retarded half-endpoint estimates hold, but the full retarded endpoint fails. In particular, the original ver...

Understanding how popular (or not) a given Web service or application is, is an important question whose relevance only continues to grow with the Internet’s commercialization. We devise Endpoint Web Monitor (EWM), a novel method capable of measuring a Web server’s popularity directly from an endpoint. We implement the EWM system and demonstrate that it achieves high measurement accuracy and ha...

Shape correspondence is the foundation for accurate statistical shape analysis; this is usually accomplished by identifying a set of sparsely sampled and well-corresponded landmark points across a population of shape instances. However, most available shape correspondence methods can only effectively deal with complete-shape correspondence, where a one-to-one mapping is assumed between any two ...

BACKGROUND In conventional PCR, total amplicon yield becomes independent of starting template number as amplification reaches plateau and varies significantly among replicate reactions. This paper describes a strategy for reconfiguring PCR so that the signal intensity of a single fluorescent detection probe after PCR thermal cycling reflects genomic composition. The resulting method corrects fo...

Let G be a graph of order n. A path P of G is extendible if it can be extended to a longer path from one of its two endvertices, otherwise we say P is non-extendible. Let G be a graph of order n. We show that there exists a threshold number s such that every path of order smaller than s is extendible and there exists a non-extendible path of order t for each t ∈ {s, s+ 1, · · · , n} provided G ...

The history of telephone networks indicates a trend of employing sophisticated switches and dumb hosts. Hence, it is often expensive and difficult to replace switches and add new applications. In contrast, Internet employs simple routers and sophisticated applications in hosts. New applications can be added without requiring infrastructural changes. In order to keep routers simple, there is a g...
