Understanding computer system hardware, including how computers operate, is essential for undergraduate students in engineering and science. Literature shows learning organization assembly language often find fundamental concepts difficult to comprehend within the topic materials. Tools have been introduced improve students’ comprehension of interaction between architecture, operating system. O...

Abstract Conceptual modeling is a learning task essential to students of computer science, software engineering and related programs. Construed as complex task, surprisingly little known about the actual act conceptual modeling, difficulties learners experience. Combining complementary modes observation learners’ processes, we study encountered while performing data task. Using concept cognitiv...

An input to the conceptual database design phase contains a description of the target database. This description is usually given in some natural language, for instance in English. Conceptual design aims at transforming English sentences into a conceptual database schema. A conceptual data model should therefore possess modeling features that can represent English sentence structures. Since Che...

The synergism among the traditional disciplines of ontology, epistemology, logic, and linguistics and their potential for enhancing conceptual-modeling applications is not fully understood. Better understanding how to adapt ideas from these disciplines should lead to improved serviceability of conceptual modeling. We argue in this position paper, however, that application objectives, rather tha...

Paper presents role of fuzzy modeling in heating, ventilating and air conditioning (HVAC) and control models. HVAC design professionals are required to evaluate numerous design alternatives and properly justify their final conceptual selection through modeling. This trend, coupled with the knowledge of experienced designers, increasing complexity of the systems, unwillingness to commit addition...

In this paper we briefly describe a new conceptual model for XML data called XSEM and how to use it for modeling XML interfaces of services in service oriented architecture (SOA). The model is a combination of several approaches in the area of conceptual modeling of XML data. It divides the process of conceptual modeling of XML data to two levels. The first level consists of designing an overal...

Studying the acceptance of Information Systems (IS) artifacts is classic to the IS research discipline, as is the study of conceptual modeling and associated phenomena. However, research has not yet sufficiently combined these two lines of inquiry to explore user acceptance of conceptual modeling. The paucity of such research has motivated our study on the acceptance of modeling grammars. In th...
