Research on education has indicated that students have different abilities and needs. In other words, they tend to learn in different ways, these ways were called a learning style. Although the learning style in many developed countries has seen a significant amount of research [1, 2], unfortunately, in Arabic region this work is still in its infancy [3–5]. The literature review revealed that there...
Blinking has two functions: to moisturize eyes and as a defensive response to the environment and responses caused by the by mental processes. In this paper, we investigate statistical characteristics of blinks and blink rate variability of 11 subjects. The subjects are presented with a reading/memorization session preceded and followed by resting sessions. EEG signals were recorded during these sessions...
When analysing software metrics, users find that visualisation tools lack support for (1) the detection of patterns within metrics; and (2) enabling analysis of software corpora. In this paper we present Explora, a visualisation tool designed for the simultaneous analysis of multiple metrics of systems in software corpora. Explora incorporates a novel lightweight visualisation technique called PolyGrid...
Presence or feel being located in virtual environment can make the Virtual Reality application more effective. One type of Virtual Reality application is Image-based Virtual Reality application; which defined as the panoramic virtual environment that mimic the real environment which users can interact with. Due to the limited interaction function, none research exists between Image-based Virtual Reality...
In order to evaluate balancing ability in each direction more objectively and analyze the correlations between balance ability and human basic information such as gender, height and weight, the complete dynamics model of balance process under external excitation was simplified as two order linear system reasonably in this study. The evaluation system based on visual stimulation was built to provide...
The software entities of an object-oriented system should be organized in such a way that "spatial relatedness entails semantic relatedness". We refer this as the tenet of "topical locality" and argue that it is fundamental for the code base to be navigable. In this paper, we propose a novel experimental framework to test this key tenet and use large-scale open-source projects...
This paper attempts to utilize social network analysis to disclose the relation structure of core journals. Journal co-citation network structure was analyzed from perspective of a social network analysis of the whole network through transforming the 29 kind management science journal's co-citation multi-value matrix into two-value matrix network. Some quantitative characteristics of the network such...
The exponential growth of Web images has created a compelling need for innovative methods to retrieve and manage them. Automatic image annotation is an effective way for resolving this problem. In this paper, we propose a novel system that automatically annotates images by semantic corpus which is constructed by mining Web image data. It includes three parts: 1) constructing the semantic annotation...
Visualization techniques have been widely used in representing software artifacts. They play a central role in conveying program information to software developers. While numerous tools have been developed to visualize information such as static software architectures, dynamic program behaviors, and debugging processes, little attention has been paid to visualizing correlations and variations among...
An empirical study is presented that investigates how stereotype based layouts impact the comprehension of UML class diagrams. This work replicates a previous study using eye-tracking equipment but uses online questionnaires instead. Subjects were given two types of tasks: one addressing UML syntax and the other addressing software design. Three different layout strategies are compared. Along with...
It is a difficult and time-consuming task to understand the source code of a complex program, even for programming experts. Software metrics or software visualization is being used for analyzing the structure of a program. Software metrics provides a way to calculate the complexity of a source code in a numeric value. And, software visualization displays the structure of a program to a geometrical...
Developers must seriously address non-functional requirements (Quality of Service) in the production of software families that include variants for different customers. Most prior research in this area deals with design and implementation aspects such as mechanisms that help implement the variability in software architecture. Few researchers have addressed how to represent variability in non-functional...
The structure of large-scale software systems are complex, and difficult to understand for developers. Traditional method can hardly describe the structural complexity in modern software. In this paper we use the complex networks theory to study software structure, in particular, we visualize software graph and use the k-core to study it based on a recursive pruning of the least connected vertices...
In 3D computer graphics, it has been an important issue to describe a virtual object realistically and show it in a physically correct manner. Unlike the virtual reality(VR), the augmented reality (AR) is an environment containing virtual and real objects simultaneously. However, the difference in motion between the virtual and real objects is obvious, which makes it hard for AR to be realistic and...
We assessed the effects of the addition of dynamic visual elements and sounds to a levee patroller training game on the appraisal of the environment and weather conditions, the engagement of the users and their performance. Results show that the combination of visual dynamics and sounds best conveys the impression of severe weather conditions and most strongly influences the appraisal of the environment...
It is a tedious and time-consuming task to understand the source code of a program, even for programming experts. Not a few methods suggested measuring the complexity of a source code, namely software metrics. But, every software metrics focuses on a specific facet of the source code and it also needs a specific knowledge of the software metric discipline to understand the metric values. In some cases,...
In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology- ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximating...
