We have tested a scheme that measures the quality of education (QoE) in the network engineering program through the progress, outcomes or any evidence of the capstone project. We use simple relations based on efficiencies but weighted and with ambiguities. For this end, the performance of students are quantified through the definition of events which are actions that can help weakly or substantially...
We consider the economic and mathematical model of forming unified information Internet space for scientific and educational resources by integration of scientific and educational resources in certain “cloud”, based on the needs of consumers, the possibility of required generation in information sources and the availability of nodes (providers) in the network to organize the process of receiving,...
This contribution extends the series of papers about virtual laboratory for control of a hydraulic system that is based on Matlab/Simulink environment. It presents the application of dynamical feedforward control for a three-tank system that can run locally or via the Internet as a virtual laboratory. The controller design uses exact linearization techniques and takes into account input saturations...
The development of Information and Communication Technologies (ICT) and the widespread growth of Internet has revolutionized the way of performing commercial operations. Due to this the organizations must reconsider the use of systemic thinking and aim their business models towards more globalized tendencies. All this has helped many companies to see the electronic commerce as a new way of on-line...
The issue of the speed of information dissemination in the environment of social networks is considered. A conceptual model is proposed based on Monod equation, where biomass growth rate depends on the concentration of the substrate. A parallel between the main data of microbiological processes and processes in social networks is drawn. The major factors influencing information dissemination speed...
In this paper, we introduce a novel active queue management scheme based on a Proportional-Integral-Derivative controller with ant colony optimization for the Internet system. The ACO algorithm searching technique is applied to search for the best gain parameters of the PID controller among a stability area. This stability region is determined using an extension of Hermite-Biehler theorem applied...
Online banking is a substantial service in the enlargement strategy of the modern bank sector. Nevertheless, this service has not been widely used, because of users are still scared of the risks of online transactions. Thus, the in-depth and distinct works of risks in risk awareness are an essential and meaningful assignment for the banking sector. This study investigates the role of perceived risk...
Owing to the transition of analogue to digital television, certain channels, that were used as guard to avoid interferences between the transmissions, are now unused. These channels are a potential medium of transmission for TVWS to bring Internet to remote areas where it's tough to install cable. To fulfil that TVWS becomes a reality, a database able to determine the unused channels in the UHF and...
The purpose of this study was to explore the important factors that influence users’ continuance usage behavior toward mobile online group-buying. Based on the characteristics of the mobile Internet, an extension of the UTAUT model is introduced to verify the proposed hypotheses. The structural equation modeling method is used to analyze the empirical data which come from universities in China. The...
Block chain technology has become a hot research in recent years, and its development will affect the whole society. In this paper, the new Life Cycle model of Power Internet Financial Products was proposed under the Block Chain effects. Some results are based on econometric mathematical model and economic principles. Meanwhile, we predict the lifecycle curve of Internet financial products based on...
The increasing use of internet and mobile devices has also facilitated tourists to select various tourism destinations. This study analyzes the factors that influence consumer purchase intention toward online travel packages available on e-marketplace websites. Data collection was conducted via a survey with 441 respondents who were members of online travel communities/forums; the results were processed...
To address the challenges raised by the Internet usage evolution over the last years, the Content-Centric Networking (CCN) has been proposed. One key feature provided by CCN to improve the efficiency of content delivery is the in-network caching, which has major impact on the system performance. In order to improve caching effectiveness in such systems, studying the functioning of CCN in-network storage...
Networked Music Performance (NMP) constitutes a class of ultra-low delay sensitive applications, allowing geographically separate musicians to perform seamlessly as a tele-orchestra. For this application type, the QoS indicator is the mouth-to-ear delay, which should be kept under 25 milliseconds. The mouth-to-ear delay comprises signal processing latency and network delay. We propose a strong collaboration...
Faced with the unrelenting traffic growth and rising costs, access ISPs (Internet Service Providers) realize that their traditional revenue model of flat subscription fees is unsustainable. Regulatory concerns, e.g., about content-specific charging, constrain the ISPs' search for new revenue sources. This paper analyzes a revenue model where an access ISP acts as a publisher of ads to users who explicitly...
There are still many people think that learning Mathematics in English causes students difficulty in obtaining a good score. Therefore, the authors conducted research related to the use of English in teaching Mathematics, for grade 7 junior high school in a private national plus school. The purpose of this study is for the reader to open up further insights related to the topic above. This research...
As the key to both offline and online business, consumers' trust to retailers always influences their purchase decision. In recent years, based on the traditional business, more and more click and mortar companies spring up. But could consumers' trust transfer from offline to online channel? And how? Extant researches lack deep exploration for these questions. In this study, introducing perceived...
Service characteristic of intangible, concurrency and heterogeneity, which make it quite normal that service error appear in the process of companies management. Despite the virtual nature of e-commerce, online retailers also have service failures. Taking group-buying websites as an example, this paper explores the factors influencing the customer satisfaction from the perspective of service quality...
This work focuses on wide-scale freight transportation logistics motivated by the sharp increase of on-line shopping stores and the upsurge of Internet as the most frequently utilized selling channel during the last decade. This huge ecosystem of one-click-away catalogs has ultimately unleashed the need for efficient algorithms aimed at properly scheduling the underlying transportation resources in...
People are suffering from a range of risks in the ubiquitous networks of current world, such as rumours spreading in social networks, computer viruses propagating throughout the Internet and unexpected failures happened in Smart grids. We usually monitor only a few users of detecting various risks due to the resource constraints and privacy protection. This leads to a critical problem to detect compromised...
With the development of the Internet, it is vital for the security of the Internet to detect web-based anomalies. Clustering based on feature extraction by manually has been verified as a significant way to detect new anomalies. But the presentations of these features can't express semantic information of the URLs. In addition, few studies try to cluster the anomalies into specific types like SQL-injection...
