Traditional security technologies are based on numerous assumptions about the environment in which systems are used. This includes assumptions about the enforcement of legislative and contractual frameworks, limitations of particular technologies and the constraints on human behaviour imposed by social and religious norms. Most of these assumptions, however, are implicit and they will fail when the...
Students often annotate texts they are reading using highlighting, underlining, and written comments and marks in the margins of the text. These may serve various functions and will reflect each student's goals and understanding of the text. This research proposes two simple biology-inspired approaches to represent the patterns of student annotations and to cluster students based on the similarity...
Studies show that, increased commercialization of education has made higher education very expensive. It will be beneficial if teachers having proficiency in the irrespective disciplines share their knowledge with the students, unable to afford higher education. However, evaluating large number of students online is very tedious and cumbersome task. Thus, it needs the automation of the evaluation...
As the researches of ITeS deal rapidly changing technology and business developments, it is like a cruising toward horizon. Although there have been considerable amount of investigations on ITeS, there are still more to study. The study includes the aspects of geography, technology and applications. This paper presets the background for the discussion.
It is argued that creating better system transparency leads to an increased understanding of a system, which gives users better indicators for placing their trust. This way of thinking is behind the author's interest for open systems. By opening up the source, the interfaces, the standardisation or the operational data, one gains the ability to better understand, and therefore to potentially trust,...
Online communities have become important places for people to seek and share expertise. Yet with the increasing number of members and produced artifacts within the communities, it is challenging to find the influential experts who post topic-specific high-quality content. This paper presents an approach to discover expertise network in online communities based on textual information and social links...
Millions of text contents and multimedia published on the Web have potential to be shared as the learning contents. However, mobile learners often feel it difficult to extract useful contents for learning. Manually creating content not only requires a huge effort on the part of the teachers but also creates barriers towards reuse of the content that has already been created for e-Learning. In this...
Image co-occurrence has shown great powers on object classification because it captures the characteristic of individual features and spatial relationship between them simultaneously. For example, Co-occurrence Histogram of Oriented Gradients (CoHOG) has achieved great success on human detection task. However, the gradient orientation in CoHOG is sensitive to noise. In addition, CoHOG does not take...
Visual discomfort has been the subject of considerable research in relation to stereoscopic displays, but remains an ambiguous concept used to denote a variety of subjective symptoms potentially related to different underlying processes. In this paper, we firstly studied the hue and saturation influence quantitatively on stereoscopic images combining the characters of human visual system (HVS). According...
The MEMOCODE design contest for 2012 is exact substring matching: a simplified form of the DNA sequence alignment problem. The challenge is to efficiently locate millions of 100-base-pair short read sequences in a 3-million-base-pair reference genome. Contestants had a month to create a fast system that ran on a given set of test data. Entries were judged both on absolute time and the product of time...
Websites serve as the presenting carriers for excellent courses construction. With the deepening of excellent courses construction and research, we have relinquished the pure evaluating display platform, and constructed comprehensive courses websites combined with teaching applications, management and display. The practice has become a tendency for the construction of excellent courses websites. In...
This paper describes an architecture for controlling non-player characters (NPC) in the First Person Shooter (FPS) game Unreal Tournament 2004. Specifically, the DRE-Bot architecture is made up of three reinforcement learners, Danger, Replenish and Explore, which use the tabular Sarsa(λ) algorithm. This algorithm enables the NPC to learn through trial and error building up experience over time in...
In this paper, we propose a new P300-based brain-computer interface (BCI) with visual stimuli being displayed on a car windshield by a Head Up Display (HUD) system. A 3*3 matrix of characters representing nine predefined locations were developed as P300 stimuli. A linear discriminant analysis (LDA) classifier with the features selected from EEG potentials by principal component analysis (PCA) was...
When user uploads a video clip to the video sharing websites, a video thumbnail needs to be generated as the cover to represent the video content. In this paper, a novel video thumbnail generation framework is presented. For generating a good thumbnail, three criteria are considered: (1) the thumbnail should be distinct, in order to make user feel more pleasant; (2) the thumbnail should be easily...
The tutorial aims at getting auditors acquainted with an application, and an equivalent open web-service, that allow straightforwardly to create, administer and analyze tests designed to measure the emotions conveyed by multi-channel and single channel media signals/stimuli (text, pictures, voice, music and sounds, video, etc.).
Goal-Setting enhances learning by providing a sense of direction and purpose. Often only a few goals are suggested, as a result many learners fail to find the goals that they can relate to. To address this problem, we propose to extract a large number and variety of goals from social media. Learners can then observe goal-based messages from others and adopt the ones they find useful. Conceptually,...
RNA-seq has the potential to discover genes created by complex chromosomal rearrangements. 'Fusion' genes formed by the breakage and re-joining of two different chromosomes have repeatedly been implicated in the development of cancer. However, although RNA-seq can detect these fusion events, normal cells are also characterized by read-through fusions across adjacent genes in the genome, or by transcription-induced...
In this paper, we propose a super multi-view display method using pinhole array for accommodation. To verify the proposed method we simulated the method and found distribution of light through each pinhole on the receiver.
Confronting conflicts and coping with them is part of social life, since conflicts seem to arise in almost every context and developmental stage of human life. The personal and collective gains that follow conflict resolution have motivated scholars across many research fields to advocate the use of pro-social mechanisms for resolution. The Siren serious game aims to support teachers' role to educate...
In order to let students learn authentically, we provide an opportunity for them to learn naturally and apply knowledge by adding authentic learning experience in classrooms. We wanted to know whether integrating embodied interactions in authentic learning can enhance authentic learning experience, and even improve learning performance. In this research, we proposed a near-authentic environment that...
