In knowledge representation reification, N-Quads and Named Graph have been introduced to represent context of knowledge, meta-information, provenance or any statements of statement. In this work we propose an attributed predicate RDF as a new alternative model in triple RDF to overcome the problem to represent statements of statement or any additional information of statement. We study that the predicate...
The paper proposes a method that helps clients to select a web service among several ones with the same functionality based on their quality of service properties (QoS). It provides a mechanism for integrated QoS assessment of web services taking into account all measured QoS properties of interest. The method estimates the strength of the mutual dependency of the QoS properties based on the data...
Acoustic radar has the advantages of low cost, high resolution, and the simplicity for sampling and storage. Recent years, it has been widely studied and applied in fields such as target detection, recognition and imaging. However, the sound signal is usually wideband. The wideband correlation function is often used in active and passive detections. To address the problems of the errors and computational...
In typical medium voltage feeder wireless current monitoring systems, the current measuring units send computed RMS values to a receiver unit. But these RMS values cannot be further processed by advanced algorithm and more information about faults cannot be extracted. To have more powerful computing capabilities, the measuring unit will have to use more powerful CPU which in turn requires higher power...
In intermittently connected ad hoc networks, a reliable path between communication endpoints may not exist because mobile nodes randomly move during their operation. Furthermore, routing protocols have to work efficiently under constraints of limited bandwidth and energy. These challenge researchers to develop a suitable protocol for the networks. In this paper, we present a new routing protocol,...
Prepaid Energy Meter has been implemented in several countries. In fact, the disadvantage of the system is the behavior control of the users. Recharging should be carried out on the meter. The problem arises when the consumers leave and the electric pulses discharged. Therefore, a system is needed to control the electrical pulse wherever they are. Prepaid energy meter is proposed and simulated by...
Currently IEEE 802.11n is widely adopted standard with a large number of users in each service area. The large number of users can significantly degrade the overall system performance and availability of the system. In this paper, the usage time limiting technique for supporting a large number of users in Wi-Fi network has been proposed. The simulation results reveal that with the suitable threshold...
The aim of this paper is to present a simplified vector control implementation without current sensors in order to reduce cost of overall system, design complexity, and improving by using proportional-integral fuzzy logic control (PI-FLC) for high performance in wide-speed-range operation. In this scheme, voltage source inverter used space vector pulse width modulation (SVPWM) technique that is good...
This paper proposes a distance measurement system for robots using a 3D stereoscopic technique, which is a new approach for solving the problem of measuring objects in a 3D image system. This can effectively measure the images precisely. Therefore, this paper focuses on the detection system and measuring the distance to an object using image processing techniques and 3D stereoscopic vision for robot...
Large-scale online learning is gaining widespread recognition and popularity. To understand student disaffection in such learning environments, this article used course review data from more than 2,390 students who completed, currently taking, or partially completed/dropped out from at least one of 8 highly-rated MOOCs. The five main reasons were: peer review activities, forum-related issues, unhappiness...
In recent years, the rapid development of intelligent dietary planning mobile systems, combined with the cloud technology, provides more intuitive and convenient experience for users on the diet recording and suggestion. However, this mobile-cloud structure will cause the privacy issue. Unlike the past researches which mainly focus on the user interface, response speed and suggestion accuracy, we...
Many diary apps have been developed for an Android mobile device. Although most concentrate on securing the privacy and adding emoticons, only a few include automatic emotion measurements. This demo shows a new diary app including real-time multi-modal emotion measurements to capture the affective state of the user from the text provided and video images made. The emotion measurements from the Emotion...

Adopting its computational resources and expert knowledge for the educational purposes, GridKa School provides excellent possibilities to gain the skills on the deployment and application of advanced software tools and techniques. This paper describes the unique concept of the...
Design science is a research paradigm where the development and evaluation of an artefact is a key contribution. Design science is used in many domains and this paper draws on those domains to formulate a generic structure for design science research suitable for small-scale postgraduate information technology research projects. The paper includes guidelines for writing proposals and a generic research...
This paper explores the use of analytical rubrics as a form of assessment and feedback in Information Technology (IT) Higher Education. Rubrics are a tool for assessment, however, they can also be used to provide a mapping of learning outcomes and graduate attributes within minimum standards to allow students to evidence their skills beyond the assignment criteria. This paper will discuss how rubrics...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Cardinality estimation of underwater network is somewhat troublesome using terrestrial node estimation methods due to unique characteristics of underwater environment such as large propagation latency, node mobility, non-negligible capture effect, and high error rate. For this reason, a cardinality estimation method based on cross-correlation of Gaussian signals is proposed for underwater network,...
