Anomaly detection is the process of identifying patterns that move differently from normal in a certain order. This process is considered one of the necessary measures for the safety of intelligent production systems. This study proposes a real-time anomaly detection system capable of using and analyzing data in smart production systems consisting...

Big Data and Cloud computing are the most important technologies that give the opportunity for government agencies to gain a competitive advantage and improve their organizations. On one hand, Big Data implementation requires investing a significant amount of money in hardware, software, and workforce. On the other hand, Cloud Computing offers an u...

The choice of the most effective stream processing framework (SPF) for Big Data has been an important issue among the researchers and practioners. Each of the SPFs has different cutting edge technologies in their steps of processing the data in motion that gives them a better advantage over the others. Even though, these technologies used in each S...

The factors affecting the student success in programming course is long being studied subject, which keeps its importance in academia. With this study, the factors affecting the students' success in introductory programming course is being analyzed, based on the results obtained from 448 students records, who took CMPE102 course in second semester...

Abstract—Usage of agile methodologies in software projects has increased recently to reduce the number of problems that may occur during the software development processes. Nevertheless, latest researches present that projects which are being developed by using agile methods also have an unexpected high ratio of problem appearance that mostly origi...

In recent years, big data and cloud computing have gained importance in IT and business. These two technologies are becoming complementing in a way that the former requires large amount of storage and computation power, which are the key enabler technologies of Big Data; the latter, cloud computing, brings the opportunity to scale on-demand computa...

The need to promote parallel computing concepts is an important issue due to a rapid advance in multi-core architectures. This paper reports experiences in teaching parallel computing concepts to computer and software engineering undergraduates. By taking a practical approach in delivering the material, students are shown to grasp the essential con...

In recent years, Cloud Computing becomes the most rapidly evolved technology. In this study, the effects of Cloud Computing on the productivity of SMEs and government agencies will be discussed. When the productivity growth is only bound to capacity increase, which leads to production increase, the cost-effectiveness and the productivity growth rem...

A new formulation for tracking multiple particles in slow viscous flow for microfluidic applications is presented. The method employs the manipulation of the boundary element matrices so that finally a system of equations is obtained relating the rigid body velocities of the particle to the forces applied on the particle. The formulation is special...

This paper is about designing a complete interactive tool, named JMathNorm, for relational database (RDB) normalization using Mathematica. It is an extension of the prototype developed by the same authors [1] with the inclusion of Second Normal Form (2NF), and Boyce-Codd Normal Form (BCNF) in addition to the existing Third normal Form (3NF) module....

In this paper, basic relational database (DB) normalization algorithms are implemented efficiently as Mathematica modules. It was observed that, Mathematica provided a straightforward platform as opposed to previous ones, mainly Prolog based tools which required complex data structures such as linked list representations with pointers. A Java user...

We examine basic elements of e-learning, the features of the e-learning model under implementation at Atilim University and the expected impact of the model on the organization of the institution. The paper also draws on examples at other institutions in discussing the issues that form the dynamics of organizational change within Universities in th...
