This paper proposes a method for contour completion of a skew-symmetry object which is partly occluded by other objects. The proposed method assumes that skew symmetry of a shape can be measured by correlation with its reflection on a no orthogonal plane. Under the assumption, the method estimates a skew-symmetry axis and a skew transverse angle, and then reflects the contour to the estimated axis...
In this paper we will present a case study and an analysis conducted to evaluate the use of lecture learning as a helpful companion to the classical teaching. This effort is done around the Opencast Matterhorn software, a system that is able to record classroom presentations and publish them on a LMS automatically, without the intervention of a technician dedicated to it. So we delivered a university-wide...
Mathematics and physics courses are recognized as a crucial foundation for the study of engineering, and often are prerequisite courses for the basic engineering curriculum. But how does performance in these prerequisite courses affect student performance in engineering courses? This study evaluated the relationship between grades in prerequisite math and physics courses and grades in subsequent electrical...
Cosmology is a data intensive field that will become more so in the coming years. In this scenario, GPU-computing is becoming very relevant for analysing large catalogs within a reasonable amount of time. In this work, we investigate the acceleration of the analysis by using a hybrid MPI-CUDA implementation.
Current human-robot-interaction research methods could benefit from an age-appropriate scale that measures children's attitudes towards robots. This paper presents the design process and evidence for the validity of the Children's Openness to Interacting with a Robot Scale (COIRS). We report findings from a pilot test on a diverse population of 172 U.S. students between the ages of 8–11. High average...
This paper presents a strategy to solve the fuzzy coalition formulation problem, which is a difficult topic in multi-agent system (MAS). Based on the grey relational theory, a grey relational grade sequence has been firstly established to describe the relationship between agent capability and task requirement. Then a strategy for fuzzy coalition formation, which combines a stimulation mechanism with...
This study attempted to develop valid, reliable, and good fit model game design scales. The first draft of instrument with fifty items was subjected to statistical analyses. Exploratory factor analysis with factor loadings of at least 0.50 was utilized to determine the dimensions and the validity of constructs. Reliability of items was ensured through Cronbach's alpha analysis. Items with alpha values...
This article addresses trust in computer systems as a social phenomenon, which depends on the type of relationship that is established through the computer, or with other individuals. It starts by theoretically contextualizing trust, and then situates trust in the field of computer science. Then, describes the proposed model, which builds on what one perceives to be trustworthy and is influenced by...
In this paper a game for working memory assessment in children between 4 to 7 years old is introduced. We evaluate the validity of the game as an assessment tool by comparing its results on a group of pre-school children with a commercially validated working memory test. Since the correctness of an assessment highly depends on the attentional state of the subject, several algorithms have been developed...
The use of educational software in teaching and learning Science, Mathematics and English are encouraged among teachers. The Ministry of Education (MOE) has provided teachers with a variety of software to achieve the objectives and goals of teaching and learning Science, Mathematics and English and also helped students to master Mathematics and Science concepts easily. The purpose of this study was...
Over the past forty years, significant research has been done on story/narrative generation in which the computer is the author. Many existing systems generate stories by filling in a template or copying an analogous story (and changing the time, place, etc.) or by prompting the user to provide a start to the story. Very few systems generate variable stories without these techniques. While it is impossible...
Information and Communication Technology (ICT) has a great potential for enriching learning experience especially in early childhood education. The need to integrate ICT at preschool level has become greater. The teacher as a mediator influences the use of ICT in teaching and learning. The aim of the research is to investigate teachers' attitudes toward use of ICT and examine whether there are a relationship...
The primary purpose of this study was to provide validity evidence for the items used to measure the intention to use an Online Discussion Site (ODS). Seventy seven students participated in this study. The extended Technology Acceptance Model (TAM) model was adapted for this study. With the use of the Rasch analysis, the item validity in extended TAM model was evaluated. There are a few aspects of...
The classification performance of previous IG algorithm may decline obviously because of the maldistribution of classes and features, due to which an improved text feature selection method UDsIG is proposed. First, we select features by classes to reduce the impact on feature selection when the classes are unevenly distributed. After that, we use feature equilibrium of distribution to decrease the...
Method of computer diagnosing is proposed by using the cluster analysis that allowed formalizing the complex processes of the identification and preventing the emergency conditions of quasi-stationary control objects. The method creates a possibility of the real time diagnosis and differentiation of diagnosed conditions as well as accounting the sliding correlation characteristics.
Sequences with desirable correlation properties have wide applications in today's communication systems. In this paper, we first extend the known results on zero autocorrelation zone of Golay sequences to 4q-QAM Golay sequences and show three constructions of 4q-QAM Golay sequences with a large zero periodic autocorrelation zone, where q ≥ 2 is an arbitrary integer. We then determine the Golay pairs...
The purpose of this research was to identify which course tracking variables correlate significantly with academic performance in blended asynchronous online courses through an empirical analysis of Learning Management System (LMS) data. In this study, course tracking variables refers to number of online sessions, number of original posts created, number of follow-up posts created, number of content...
This paper gives a detailed report on the correlation analysis of computer-assisted oral English test achievements with computer preference on the case study of 131 non-English majors in Wuhan Polytechnic University. Statistical analysis indicates that there is no significant correlation between these two factors, however, those who don't prefer to have tests or study English on computers score much...
Cloud computing is not just a buzz-word, it represents a strong direction of IT industry development. Speaking of cloud computing we should distinguish three different service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). The scope of this work is a model of Software as a Service. This represents the lease of computing resources on a network...
High schools have rapidly adapted computers in their administration, management and academy. School management uses papers and computers as tools to store the administrative and management data. However computers are not used to analyze data and output information. Therefore, e-School Management System (e-SMS) is developed to facilitate teaching and administration staffs to manage school activities...
