User feedback is crucial to improve software quality. For example, it can be used to identify missing features and clarify user trends and preferences for future improvement. However, obtaining user feedback is not a 'one-off' process which requires that developers need to gather user feedback in an on-going approach. The problem lies here: the majority of users are generally lack motivation and interest...
The aim of subspace clustering is to find groups of similar data points in all possible subspaces of a dataset. Since the number of subspaces is exponential in dimensions, subspace clustering is usually computationally very expensive. The performance of existing algorithms deteriorates drastically with the increase in number of dimensions. Most of them use bottom-up search strategy and there are two...
In recent years, the work on expressive styles of speech has increased rather than focusing on basic emotions. The present paper shows the comparison of expressive speech and neutral speech on the basis of pitch and intensity where neutral speech can be further modify to produce expressive style with emotion which is suitable for story telling application. Our approach is to perform an analysis of...
We propose a Cloud Advisor framework that couples two salient features: trustworthiness and transparency measurement. It provides a mechanism to measure trustworthiness based on the history of the cloud provider taking into account evidence support and to measure transparency based on the Cloud Controls Matrix (CCM) framework. The selection process is based on a set of assurance requirements that...
The paper employs gradient dynamics (GD), in addition to Zhang dynamics (ZD), to generate new fractals which are quite different from the conventional Newton fractals (NF). The proposed gradient fractals (GF) have three types. Specifically, via appropriate iterative formulas derived in complex domain, the first-type and second-type fractals are generated, i.e., 1GF and 2GF. By expanding the conventional...
Utilization of semantic web technologies in educational systems is rapidly expanded, bringing new and more efficient teaching and learning capabilities. Semantic Web Based Educational Systems (SWBEs) rely on semantic web technologies and are proved to be more intelligent and personalized to the students learning needs. In this paper, we present a semantic web based adaptive educational system that...
This paper studies and evaluates Technology Enhanced learning, with particular reference to the National Program for Technology Enhanced Learning (NPTEL) a portal dedicated to technical e-content across different Engineering Colleges of India. Based on a comprehensive survey conducted across the Engineering Colleges with over 5161 respondents, predominantly from western India, this study is a quantitative...
Bond percolation is a network process that traditionally addresses the question when there is a path between two sites or two clusters in a network. This has been used to study the circulation of goods or flows in networked structures as well as network resilience. This paper proposes and analyzes a dynamic bond percolation model where bonds (i.e., edges) open (i.e., form) or close (i.e., terminate)...
Mobile applications are widely used in many research areas as well as in current daily life. Applications on smart phones are closely related to the physical device. An application may run differently on different mobiles. It is hard and expensive for college students to adapt and test their applications on several types of smart phones. This paper presents a work in progress on the development of...
In order to acquire infrequent events as new ideas and evaluate the ideas quantitatively, it is necessary to know how people create and refine ideas and to model creating and refining process. In this paper, we focused on relations between thinking time and writing time in handwriting, and proposed to model the relation by externalization, classification, relation, transportation and systematization,...
Currently, some universities and colleges in Palestine use a traditional assessment method to evaluate their faculty members' performance each semester, while some use e-forms that are being evaluated manually. However, these processes are not flexible or accurate enough to give fair and non-prejudiced feedback. Moreover, it takes a long time to ensure the information quality of the data inputs as...
In all European countries, initiatives are implemented towards promoting the use of Information and Communication Technologies (ICT) in schools. However, the current level of school ICT uptake remains low, due to the interrelation of a wide range of factors, including teachers' ICT competences and strategic school Leadership planning. In this context, there is a need for systems that will facilitate...
Computer games have been exploited in educational procedures, since they help in fostering creativity, in familiarization with technology, and develop problem-solving, logical thinking, communication, and collaborative skills (Sicart 2009). Games is a symptom of our societies and offer learning and strong educational advantages, as they fully motivate and engage students. The term “game” refers to...
Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common psychiatric conditions in childhood. Observation of the behavior of the young person plays a key role in Cognitive-Behavioural (CB) approaches to the treatment of ADHD, but traditional pen and pen-and-paper based methods have a number of disadvantages which inhibit their use in realworld situations. The WHAAM mobile application...
Pseudo-color images are widely used on World-Wide-Web (WWW) to reduce file storage, RAM, video memory buffer space, and to speed up data transfers. A pseudo-color image consists of indices and indices are stored in a file with raster scan order. The investigations on different scanning patterns in filing of indices showed that further improvements on compression are possible. In this paper, we propose...
In order to successfully deliver Mobile-Based Assessments in any educational setting, it is of great importance to investigate the factors that influence its adoption from the students. The present study aims to explain and predict the Technology Acceptance Model constructs “Attitudes towards Using” (ATU) and “Intention to Use” (ITU) mobile-based assessment from the perspective of the Self-Determination...
Having implemented a Classroom Response System (CRS) “Tweedback” in style of Social Media, this instrument was supposed to be evaluated for further rework and refinements. However, systematic evaluation of such applications is rarely done and demands a determination of the issues to be considered within the evaluation. The scope of the approach presented in this paper is the evaluation with regard...
This study sets out to tackle some of the challenges that science teachers face in adapting to an Inquiry Based Learning (IBL) approach in their teaching. The purpose of this action research inquiry was to encourage teachers to take part in peer based online webinars in order to learn how to incorporate inquiry based learning (IBL) using narratives and etools in their teaching. The research emerged...
