ThingLab - An Object-Oriented System for Building Simulations Using Constraints
نویسنده
چکیده
ThingLab is a system that provides an environment fo r bui ld ing simulations. Wi th in this environment, a simulation is organized as a collection of objects that interact wi th one another by sending and receiving messages. Each object has a table of named properties, which describe both the internal state of the object and its protocol fo r sending and receiving messages. An object may have one or more parents, thus providing for inheritance of properties. The interactions of the objects in a simulation are specified in terms of constraints. The operation of merging is used to specify connectivity and to combine properties inherited f rom several parents.

Objects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques
Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...

Software architecture is one of the most fundamental products in the process of software development in the areas of behavioral or non- behavioral features like availability or transformability change. There are different ways to evaluate software architecture one of which is the creation of application model. An executable model of software architecture is an official description of architectu...

An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...
متن کاملOn Attributes of Objects in Object-Oriented Software Analysis
One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...
