This paper presents the conceptual design and application of a new land-change modelling framework that represents geographical, sociological, economic, and ecological aspects of a land system. The framework provides an overarching design that can be extended into specific model implementations to evaluate how policy, land-management preferences, and land-market dynamics affect (and are affecte...

Lower prices, shorter product cycles, and the customer individual production of highly variant products are the main reasons for the success of product configuration systems in various application domains (telecommunication industry, automotive industry, computer industry). In this paper we show how to employ UML in order to design complex configuration knowledge bases. We introduce the notion ...

The primary objective of a knowledge-based system (KBS) is to use stored knowledge to provide support for decision-making activities. Empirical studies identify improvements in decision processes and outcomes with the use of such knowledge-based systems. This research suggests that though a KBS is primarily developed to help users in their decision-making activities, as an unintentional consequ...

In this paper, we present an approach to define the semantics for object-oriented modeling languages. One important property of this semantics is to support underspecified and incomplete models. To this end, semantics is given as predicates over elements of the semantic domain. This domain is called the system model which is a general declarative characterization of object systems. The system m...

This paper addresses the integration of system modeling and software modeling, particularly for embedded systems, which are software intensive systems that consist of both hardware and software components. This paper describes a systems modeling approach to create structural and behavioral models of the total system using SysML. The systematic transition to software modeling using UML is then d...

despite the crucial role of introductory sections in argumentative academic writing, the effects of genre- based approaches to writing introductory paragraphs have not been much explored yet. the present study aimed to investigate whether the provision of genre knowledge through modeling and non-modeling could enhance learners’ ability in writing introductory paragraphs of argumentative essays....

there are instances in which it is desirable to determine relationships among fruit physical attributes. for example, fruits are often graded on the basis of size and projected area, but it may be more suitable and/or economical to develop a machine which grades by mass. therefore, a relationship between mass and dimensions or projected areas and/ or volume of fruits is needed. various grad...

parachor based expressions (basic and mechanistic) are often used to model the experimentally observed pressure dependence of interfacial tension (ift) behaviors of complex supercritical carbon dioxide (sc-co2) and crude oil mixtures at elevated temperatures. however, such modeling requires various input data (e.g. compositions and densities of the equilibrium liquid and vapor phases, and molec...
