Domain ontology plays an essential role in formalization and sharing of domain knowledge. However, constructing domain ontology is a labour intensive and time consuming engineering. To efficiently represent knowledge as a set of concepts and relations within domain ontology, a 5W1H method is proposed to analysis concepts and relations of it from six aspects including Who, When, Where, What, Why and How. The theory and methodology of modelling domain ontology based 5W1H is also presented in this paper. Take Expert Ontology in expert information domain for an example, six-layer framework for conceptual model of expert ontology based 5W1H is designed, and conceptual model of expert ontology is constructed, in which concepts and relations within expert ontology are defined. Application shows that the 5W1H modelling method is flexible and scalable, because it is not only able to assist ontology engineering to construct domain ontology quicker and more accurately, but also adaptable to business changes and user requirements. In addition, it is helpful to define reasoning rules for inferring knowledge and to share domain knowledge.

The purpose of this study is to examine the effect of prestige sensitivity on mobile phone customer’s price acceptance in Vietnam and the mediating role of product knowledge and price mavenism on this relationship. We used the convenience sampling method for data collection via questionnaires with a sample of 605 consumers who purchased mobile phones. The collected data was analysed by applying a structural equation modelling method. The result indicates that prestige sensitivity has both direct and indirect effects on price acceptance via product knowledge and price mavenism. The findings suggest that prestige sensitivity can be used as a market segmentation criterion for mobile phones when making price decisions and providing customers with adequate information could improve price acceptance.

Steady-state modelling method for matrix-reactance frequency converter with boost topologyThis paper presents a method intended for calculation of steady-state processes in AC/AC three-phase converters that are described by nonstationary periodical differential equations. The method is based on the extension of nonstationary differential equations and the use of Galerkin's method. The results of calculations are presented in the form of a double Fourier series. As an example, a three-phase matrix-reactance frequency converter (MRFC) with boost topology is considered and the results of computation are compared with a numerical method.

Modelling Approach

A modelling approach that will facilitate an in-depth understanding of the interactions of the different phenomena, human interactions and environmental factors constituting �real world� industrial processes is presented. An important industrial system such as Gas Processing Unit (GPU) have inter-related internal process activities coexisting with external events and requires a real time inter-disciplinary approach to model them. This modeling framework is based on identifying as modules, the part of processes that have interactions and can be considered active participants in overall behaviour. The selected initial set of modules are structured as Petri net models and made to interact iteratively to provide process states of the system. The modeling goal is accomplished by identifying the evolution of the process states as a means of effective representation of the �actual running�� of the industrial process. The paper discusses the function and the implementation of the modelling method as applicable to the industrial case of GPU.

Applications of modern terminal loads and its relevant disadvantages are described in this paper. The decomposing method of wideband microwave high power microstrip loads design is proposed in this paper with purpose of matching quality improving. Multiple extension of multistage load bandwidth is provided by using of external matching circuit and internal matching inductive elements. The maximum reachable bandwidth of multistage load is estimated and optimal values of mathing circuit elements are founded on basis of equivalent lumped scheme. The topology of microstrip two-stage high power microwave load is developed and its frequency response, calculated via numeric electrodynamic modelling method is outlined in the paper. Modelling results show good matching quality of considered load at the frequency band below 3,5 GHz.
