This paper analyzes difficulties with the introduction of object-oriented concepts in introductory computing education and then proposes a
two-language, two-paradigm curriculum model that alleviates such difficulties. Our two-language, two-paradigm curriculum model begins with teaching imperative programming using Python programming language, continues with teaching object-oriented computing using Java, and concludes with teaching object-oriented data structures with Java.
This paper presents the results of our data mining study of Pb-Zn (lead-zinc) ore assay records from a mine enterprise in Bulgaria. We examined the dataset, cleaned outliers, visualized the data, and created dataset statistics. A Pb-Zn cluster data mining model was created for segmentation and prediction of Pb-Zn ore assay data. The Pb-Zn cluster data model consists of five clusters and DMX queries. We analyzed the Pb-Zn cluster content, size, structure, and characteristics. The set of the DMX queries...
This paper describes a PC-based mainframe computer emulator
called VisibleZ and its use in teaching mainframe Computer Organization
and Assembly Programming classes.
VisibleZ models IBM’s z/Architecture
and allows direct interpretation of mainframe assembly language object
code in a graphical user interface environment that was developed in Java.
The VisibleZ emulator acts as an interactive visualization tool to simulate
enterprise computer architecture. The provided architectural components
include...
