This paper presents a model of a navigation system in a public information system, that can be used to improve the structure and content of the information repository via self-organization capabilities based on social interaction. This model has the primary goal of establishing a generic and adaptive social-based self-structuring navigation system. To achieve this goal, the model integrates the concepts...
Complexity of tsunami modeling requires designing software system with high level of reusability and interoperability of its components, and flexible resource management. In this paper we investigate how to integrate the tsunami modeling software with an agent-based resource management infrastructure.
This paper presents a concept of a software platform and a method of hybrid composition of web services and hybrid grounding of abstract composition plans. The paper also describes the architecture of the implemented platform and its modules.
This paper presents a developed higher education quality assessment model (HEQAM) at King Abdulaziz University (KAU). This is because of; there is no universal unified quality standard model that can be used to assess the quality criteria of higher education. Besides, there are shortcomings in the coverage of some current educational quality standards. A Developed questionnaire to examine the quality...
Advances in web services and open network interfaces enable development of new user-oriented applications in different areas of digital life. Among them, digital entertainment is one of fastest growing networked application domains. Technologies like CDNs (Content Delivery Networks) and HTTP streaming opened the way for new models of TV and video consumption over the Internet. Thanks to emergence...
This article regards analysing the literature of processing competence in education, as well as competence management systems (CMS) and their role in developing competencies for students of higher education cycle. The Bologna Process and its results are described later in the text, explaining the need for National Qualification Frameworks and the benefits that they can produce when implemented correctly...
Intrusion detection systems have been around for quite some time, to protect systems from inside ad outside threats. Researchers and scientists are concerned on how to enhance the intrusion detection performance, to be able to deal with real-time attacks and detect them fast from quick response. One way to improve performance is to use minimal number of features to define a model in a way that it...
Brief description of the author's results of development of cognitive processes (CP) computer modelling concept on the basis of improving the methodology and expanding the area of using computer-based testing technology in education is suggested. The fundamental heuristics for formalizing: the concept of degree of difficulty of test tasks (TT); the degree of confidence of individual's CP concept;...
E-learning is a contemporary teaching tool that has become popular and widely used in engineering education in recent years. This article presents the outcomes of a study on considering students' different learning styles in teaching information and communication technology using e-learning. Students were divided into two study groups. The reference group studied according to a provided learning model...
Many carpool and ride-sharing solutions have been proposed and even developed in the previous decades, but rarely have they been able to attain a global user base, at least not up until recently. That was mostly because many of them were not initially designed as scalable, leaving their users with a sub-par user experiences as their user base grew, and often their mobile or desktop client reach was...
EDUCache simulator [1] is developed as a learning tool for undergraduate students enrolled the Computer Architecture and Organization course. It gives the explanations and details of the processor and exploitation of its cache memory. This paper shows a set of laboratory exercises and several case studies with examples on how to use the EDUCache simulator in the learning process. These hands-on laboratory...
The article concerns the process of developing biometric devices with a view to submit them for certification in compliance with ISO/IEC 15408 Common Criteria. The author points at the assurance paradigm which shows that the source of assurance is a rigorous process of the product development along with methodical and independent evaluation in an accredited laboratory. The state of the art of certified...
The paper presents case study - Information Systems and Computer Science in Civil Engineering curricula. Introduction gives historical background of present role and position of IS, Information & Communication Technologies (ICT) and CS. Later details of the course of Information Technologies (IT) are presented in which elements of IS (ICT) and CS are combined. The use of spreadsheet and its Solver...
In this paper we propose new approach in data set dimensionality reduction. We use classical principal component analysis transformation. Instead of rejecting features we generate new one by using nonlinear feature transformation. The values of transformation weights are changed evolutionary by using genetic algorithms. Results show better classification rates in smaller feature space. Visualization...
This article deals with universal sequential audio pattern search and sound recognition method. Inspired by classical phoneme-based speech recognition and word spotting systems, where longer speech patterns are formed by sequences of basic speech units, we propose a methodology for creating a finite database of elementary sound models. These models can be arbitrary concatenated into sequences, thus...
The paper presents new Microformat and Microdata schemas for creating descriptions of interactive 3D web content. Microformats and Microdata are increasingly popular solutions for creating lightweight attribute-based built-in semantic metadata of web content. However, although Microformats and Microdata enable basic description of media objects, they have not been intended for 3D content. Describing...
Experts are able to predict sales based on approximate reasoning and subjective beliefs related to market trends in general but also to imprecise linguistic concepts about time series evolution. Linguistic concepts are linked with demand and supply, but their dependencies are difficult to be captured via traditional methods for crisp data analysis. There are data mining techniques that provide linguistic...
We introduce the architecture and the data model of the software for integrated access to music searching web services. We illustrate our approach by developing a mobile accessed application which allows users of Android running touch screen devices accessing several music searchers including Musipedia, Music Ngram Viewer, and FolkTuneFinder. The application supports various styles of music input...
