Two-Language, Two-Paradigm Introductory Computing Curriculum Model and its Implementation

Zanev, VladimirRadenski, Atanas — 2011

Serdica Journal of Computing

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.

Analysis and Data Mining of Lead-Zinc Ore Data

Zanev, VladimirTopalov, StanislavChristov, Veselin — 2013

Serdica Journal of Computing

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...

VisibleZ: A Mainframe Architecture Emulator for Computing Education

Woolbright, DavidZanev, VladimirRogers, Neal — 2014

Serdica Journal of Computing

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...
