With the transition toward a smart grid, the power system has become strongly intertwined with the information and communication technology (ICT) infrastructure. The interdependency of both domains requires a combined analysis of physical and ICT processes, but simulating these together is a major challenge due to the fundamentally different modeling and simulation concepts. After outlining these...
Text compression based on graph representation model (referred to as “text graph”) is a fairly common approach. However, one of the difficult issues that this approach poses is how to identify nodes that have co-reference relationships in a text graph? This issue is a question that needs to be answered because previous studies have confirmed that it has a great influence on the quality of the summaries...
Because of the present deep impact of information technology on society, school subjects that deal with topics of computer science or digital literacy gain importance nowadays. Some countries start to teach related topics in primary education and even in kindergarten. The underlying curricula, educational standards and/or competency models have already been developed and established and differ in...
This study aimed to aid the enormous effort required to analyze phraseological writing competence by developing an automatic evaluation tool for texts. We attempted to measure both second language (L2) writing proficiency and text quality. In our research, we adapted the CollGram technique that searches a reference corpus to determine the frequency of each pair of tokens (bi-grams) and calculates...
The aspect of users' behavior (user acceptance) is one of the main factors that determine the successful application of information technology. Student Center Activity and Learning of Harapan Bangsa (Scalsa SHB) brings about transformation in the method of learning from the manual system to the electronic one, which results in the attitude and behavior of the users to accept and use it. This research...
With the rapid development of informatization and the popularity of computer application, higher requirements are put forward for computer teaching in university. As one of the basic courses in universitie, “Computer Sience” carried out some reforms in the teaching content, but the teaching method is still based on instruction, supplemented by the computer exercises. The paper puts forward the blended...
Fog computing has emerged as a promising solution for the Internet of Things (IoT) and next generation mobile networks. As an extension to cloud computing, it enables service provisioning along the continuum from the cloud to things for reducing latency and bandwidth demands, and for empowering end users in their vicinity. Specifically, fog computing can pool resources anywhere along this continuum...
Although many adaptive background subtraction methods have been proposed for image-based foreground detection, dynamic background in the scene, such as an electronic billboard, still causes a serious problem of false alarm. Exclusion of such area from region of interest may prevent the problem, however an issue of security hole on that area becomes another concern. A method of change detection on...
Rain attenuation prediction models for link analysis are essential for satellite communications. The diurnal variations of the rain attenuation statistics are valuable for the effective system designs. In this work, a simple prediction model for diurnal rain attenuation statistics with its conversion scale is proposed. The method of calculating an approximated optimal constant conversion scale was...
We propose a method for automatic modeling of electronic devices using a prefix-suffix approach. We implement it into a user-friendly computer program and give preliminary results supporting the validity of our approach. Patterns of prefixes and suffixes are obtained. We find two patterns giving 100% correct detection of supply current in 10 regulators' datasheets from Texas Instrument Inc.
Information sharing among e-marketplace consumers can reflect trust and distrust in products and sellers. Trustworthiness of products and sellers helps consumers to make a good purchase decision. E-marketplace websites, who encourage consumers to rate their products using only a single dimension such as five-star rating system, is unable to reveal the consumer satisfaction in details. In this paper,...
With the rapid development of information technology, blended learning theory in higher education has become more and more maturing, many experts and scholars at home and abroad are interested in this field. In this paper, we selected the information economics course as the observation, and observed the students during the period from 2014 to 2016,. In the experiment, some students learned in traditional...
Cloud computing is no longer a myth for organizations, on the contrary. With the creation of the Brazilian Army Information Technology Pole, they also understands that migration to a cloud environment can help to improve the provision of services to its internal customers, modernizing its infrastructure. There are several solutions on the market, proprietary and open source, offering the possibility...
Cloud Computing is a type of internet based service provider, where resources can be shared among users. Transparency is a key issue in CC, where clients are unaware of the source of the service requested. CC services can be in a form of applications, storage, and others. Services provided by different clouds differ in many criteria such as cost and response time. This paper presents a mathematical...
Elasticity feature is the most important asset for cloud-based systems compared to other technologies. This property grants the ability to dynamically adjust cloud resources allocation when needed in autonomic manner. The efficient management of cloud elastic system is a challenging task. This paper proposes an approach based on multi agent system for Cloud of Clouds Elasticity Management. The Interacting...
A sequence diagram is one of UML models that are usually used within the analysis phase in software system development. Since generating such sequence diagrams is performed manually, automated or semi-automated support is beneficial in providing important and practical help. In this paper, a new semi-automated approach for generating sequence diagrams from user requirements written in Arabic is proposed...
Software reuse has long being recognized as an important area amongst the software development companies in improving productivity and quality of their product. Reusing of early-stage software artifacts such as UML state machine diagrams increases the benefit reaped from reuse because it allows the reuse of related later-stage artifacts. Among the reuse task, matching and retrieval of similar artifacts...
This paper demonstrates a comparative study of Arabic Multi-Document Summarization System (AMD-SS). These methods are compared and analyzed, aiming to detect which method generates a genuine summary and achieves the best results in comparison with the human summarization techniques. The comparative study shows that there is a lack in the area of Arabic Automatic Text Summarization systems. Therefore,...
Cloud computing has emerged as a new computer term that relates to provide reliable computing environments, based on a better quality of service and availability of the infrastructure without a major financial burden. The cloud computing has become a very active area of research, with the emergence of business process management (BPM) in the cloud, where the adoption of BPM with Cloud Computing has...
Evaluating and scoring essay questions is an exhausting, time consuming process and require a lot of effort. So, applying automated tools is essentially required to tackle these drawbacks. In this study, we propose an automated scoring approach for short answers to Arabic essay questions. The scoring process is based on the similarity between the student's answer and model answer, cosine similarity...
