This paper describes a system for constructing conceptual graph representation of text by using a combination of existing linguistic resources (VerbNet and WordNet). We use a twostep approach, by firstly identifying the semantic roles in a sentence, and then using these roles, together with semi-automatically compiled domain-specific knowledge to construct the conceptual graph representation.

Fully reusable spaceplanes do not exist as yet. This implies that design-qualification for optimized highly-integrated forebody-inlet configuration of booster-stage vehicle cannot be based on archival data of other spaceplanes. Therefore, this paper proposes a novel TIPSO-SVM expert system methodology. A non-trivial problem related to optimization and classification of hypersonic forebody-inlet...

The cover by Thanh-Duong Nguyen shows the development of novel chemically bonded tribomaterials based on polyamides, irradiated polytetrafluoroethylene, and oil molecules. materials are formed through a twostep process reactive-extrusion. This article presents compound's morphology, crystallization behavior, mechanical properties. It was found that PA12-(Z7321) offered best coupling degree is m...

In wireless sensor networks, collection of raw sensor data at a base station provides the flexibility to perform offline detailed analysis on the data which may not be possible with innetwork data aggregation. However, lossless data collection consumes considerable amount of energy for communication while sensors usually have limited energy. In this paper, we propose a Distributed and Energy ef...

Illuminating tissue with pulsed electromagnetic waves generates acoustic waves inside an object which can be measured and converted into a three dimensional (3d) image. This text is concerned with a twostep reconstruction method where the acoustic pressure is measured with circular integrating detectors. In the first step reconstruction formulas for some kind of projection of the source distrib...

This chapter provides an in-depth introduction to database replication, in particular how transactions are executed in a replicated environment. We describe a suite of replication protocols and illustrate the design alternatives using a twostep approach. We first categorize replication protocols by only two parameters and present a simple example protocol for each of the resulting categories. F...

This study evaluated and compared the performance of two real-time PCR assays using nested reverse transcription (RT)-PCR as the reference method. Among 117 nested RT-PCR-positive cases, the abTES DEN 5 qPCR kit detected 97.4% of dengue virus (DENV) infections, while the innuDETECT Dengue TwoStep assay did so for 44.4%. Sensitivity varied by infecting serotype and the stage of infection. The ab...

This paper deals with the convergence and stability of linear multistep methods for impulsive differential equations. Numerical experiments demonstrate that both the mid-point rule and twostep BDFmethod are of order p 0when applied to impulsive differential equations. An improved linear multistep method is proposed. Convergence and stability conditions of the improved methods are given in the p...
