In this paper it is presented a new application of Levenshtein distance algorithm, for the selection of choices in a vocabulary quiz. Levenshtein distance is a measure for the similarity of two strings. In order to make the quiz more difficult, the choices for the correct word are selected using the calculated degree of similarity with the correct word. We developed a Java graphical application that...
In this paper, we will describe a statistical study of data analyzed by SPSS software. The aim of our study is to show the importance of sharing emotional states between learners during online communication, which helps to create an adequate environment and a positive cognitive exchange between the teammates. Our study is based on three stages. The first, discussed the satisfaction of learners with...
The development of three modular Rabin's encryption algorithm with using ordinary integer and modified perfect forms of the system of residual classes is presented in this paper. This method takes precedence over classic in choosing modules of the same order in sustainability by increasing the block of plaintext for encryption. New methods for implementation of major labor-intensive operations of...
Prospective memory can maintain our ability to living independently, which is important for our daily lives. Evaluation of prospective memory can be reflecting the severity of cognitive ability regression. Previous studies developed slide-based task and living-based task to evaluate prospective memory performance in different conditions. However, as a new technology that can provide a more realistic...
The design of human-computer interface is important and complex. Concerning the Chinese character legibility, three elementary factors are included in this study, namely, age, lighting environment, and font size. 176 subjects divided into three different age groups (19∼35, 35∼55, above 55) participated in the experiment of recognizing four font sizes (6, 9, 12, 24) in three different lighting environments...
Enrolments in North American undergraduate computer science have been booming in recent years, and many CS departments have been struggling to meet student demand. We surveyed 78 CS professors, instructors, staff, and administrators to see how the enrolment boom has been affecting their practice; and to see how departments are responding in terms of policy. We asked participants to tell us what factors...
In this paper, we propose an alternative option to digital scrum board using leap motion device. We apply a leap motion device to control and perform activities on digital scrum board for improving team communication during a daily meeting. It is more convenient way for the scrum team to present and control the digital scrum board, rather than using a mouse pointing device, especially during participating...
Collaborative and inquiry learning in the Virtual Learning Community is a new kind of online learning. The learners construct their own knowledge by interactive learning in the community. Some log records and related learners' learning behavior information is generated in the experimental platform of the virtual learning community. Statistical tools of SPSS and Excel are used to explore the learning...
In this paper, the solution of limit problems, which is an important subject of high school and university mathematics is presented by using JavaCC code generation tool and symbolic computation methods. Although JavaCC is generally used for generating programming language interpreters, in a similar way it can also be used in the evaluation of mathematical expressions. In this work, first the general...
Keylogger is a specific type of spywares, that attempts to steal user information, by keep tracking user keyboard, and log every keystroke in a log file; to be used by a third party. Keylogger is one of the most serious problems which blustering information security in this era. And it still considered an open problem. Most of the keylogger softwares available, intercept the key after it has been...
Because of the requirement of the home office, remote computer equipment, centralized management, distance learning, and training, the remote control software is fast developing. This paper describes the design and the realization of the remote control software, as well as the design experiment of the remote control software. At last, we also test the remote control software which we design with C++...
This paper retrieves information and makes basic analysis about the participation of users involved in Cooperative MOOCs in Learning Communities supported by hypermedia environments like the social networks. In order to perform this study, the interaction of a set of users enrolled in a course within the iMOOC platform has been analyzed, in which MOOC courses are implemented based on concepts like...
Nowadays, university students are evaluatedusing paper-and-pencil tests in addition to e-tests. Ahundred university graduate and undergraduate studentsin a private university in Lebanon were surveyed to studytheir attitudes towards taking e-tests in comparison totaking paper-and-pencil tests. The results of this casestudy showed that the majority of the students felt lessanxious while taking e-tests,...
With the rapid development of CTI and VoIP technology, more and more attention is paid to the voice mailbox based on VoIP which is a kind of important telecom value-added service. In order to reduce the voice mailbox system development cost and shorten its development cycle, a solution of the voice mailbox system based on digital voice card and VoIP is put forward in this paper. This paper introduces...
Algorithms of finding polynomials roots have been proposed and they are continuously suggesting in different works [5] which are devoted for solving as theoretical so application problems because of theirs complexity and sufficient perfection (accuracy) in series of certain situations. A method of finding polynomials roots which is reduced to obtaining analytical representation of polynomial roots,...
Games have redefined the way humans interact with computers and challenged the traditional definitions applied to narratives. Narratologists and ludologists have used a variety of approaches taken from their respective fields to study game narratives. The current study creates a measure of narrativity based on existing literature to plot the game chosen for analysis. Using the ontic dimensions (World,...
Video games are becoming less and less usable by people with disabilities every day. These disabilities include cognitive, visual, and mobility. The purpose of this paper is to discuss the necessity of making video games accessible. This will be done through looking at benefits, current work for all disabilities, and how it's looked at by the law. The topic of video gaming accessibility is especially...
Living in the knowledge age, we acknowledge that new ideas and innovative products are the new sources of economic growth. Technologies play a critical role in knowledge-based economy in several ways For example, internet is one of the main conduits for learning new skills and information that are necessary in a knowledge-based economy. Technologies, at the same time, also drive changes in education...
Radix conversion for conventional number systems can be computed using one of the four algorithms reviewed and discussed in [1], depending on whether the source or the destination radix arithmetic is used and whether an integer or a fraction is to be converted. Out of the four radix conversion algorithms, expensive division operations are required in two of them. In this short paper, two new radix...
This paper presents a new way to build, maintain and improve routine phonetic systems using the concept of automatas. An adaptive automata tool known as Adaptools was used to show how automatas work on phonetic routine systems. Phonetics rules for Brazilian Portuguese were implemented using this tool and later, the rules were modified and other news were added to the automata to show the complexity...
