The advantages of object-oriented (OO) programming are well-known. Nevertheless, distributed OO middleware systems (OOM) such as CORBA, DCOM or Java RMI have not been widely adopted for the developing of Internet applications. Developers seem to perceive OOMs as overcomplex, proprietary or incompatible with current WWW development practices. Recognizing these difficulties more WWW-friendly prop...
While there are many aspect-oriented modeling (AOM) approaches, from requirements to low-level design, it is still difficult to compare them and know under which conditions different approaches are most applicable. This comparison, however, is crucially important to unify existing AOM and more traditional object-oriented modeling (OOM) approaches and to generalize individual approaches into a c...
modeling and simulation of processing plants are widely used in industry. construction of a mathematical model for a plant is a time-consuming and error-prone task. in light of extensive advancements in computer science (both hardware and software), computers are becoming a necessary instrument in industrial activities. many software tools for modeling, simulation and optimization of processing...
reservoir dams are among the main storage systems employed in agriculture for the several past decades. proper operation of these reservoirs is important for irrigation espe-cially in such arid and semi-arid areas like iran, and particularly during dry years. a computational framework for reservoir simulation and flood routing is hereby presented. a key aspect of the reservoir simulation is the...
in recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. in the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. in this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (oopls) us...
-In today’s world designing adaptable course material requires new technical knowledge which involves a need for a uniform protocol that allows organizing resources with emphasis on quality and Learning. This can be achieved by bundling the resources in a known and prescribed fashion called Learning objects. Learning Objects are composed of two aspects namely “Learning “ and “Object”. The Learn...
The authors introduce the exploration of object-oriented basic concepts as a new approach to object-oriented modelling (OOM). While other subjects have a long tradition in learning by discovery with suitable learning aids (e.g. experimenting installations of the scientific subjects), Informatics at first has to define and to develop such learning aids. Therefore software development environment...
The authors introduce a didactic system for object-oriented modelling (OOM) as a new and flexible learning concept for informatics education and outline a development methodology which is in evaluation. With the aim to improve the quality and individualization of lessons the following components of a didactic system have been identified so far: and-or-graphs for the representation of the knowle...
Object-Oriented Models (OOM) are widely used in ModelDriven Engineering (MDE). As a complement, OCL constraints are used to specify business rules and detailed aspects of the business domain. Automatically co-evolving OCL constraints w.r.t. the evolved OOM is challenging since alternative resolutions can be applied but also a resolution cannot be applied to any arbitrary constraint. In this pap...
The traditional notion of instantiation in Object-Oriented Modeling (OOM) requires objects to be complete, i.e., be fully certain about their existence and attributes. This paper explores the notion of partial instantiation of class diagrams, which allows the modeler to omit some details of objects depending on modeler’s intention. Partial instantiation allows modelers to express optional exist...
