Serious games can be used as learning tools since learning games are more in correspondence with the current generation of students, foster students' motivation, and increase the learning effects, making learning meaningful to students. This paper presents a conceptual model for representing designs coming down to a puzzle-based game implementing an active learning method that describes the activities flow for learners. Each activity refers to a collection of puzzle pieces needed to perform the activity. In order to support the performance of individual activities, micro-scaffolding support, such as question or hints, can be also defined using our proposed model.

Shape memory alloy is one of the materials classified as 'smart' materials. Its anomalous behaviour has gained more attention in the field of engineering. There are numerous mathematical models that have been developed to analyze its behaviour. In this paper, a newly developed constitutive model for shape memory alloy is presented. The features of the newly developed model are presented and compared with some of the existing models.

In this paper first a system of ordinary differential equations is formulated for an extended SIR influenza model. In our model, the emergence of drug resistance and the evolution of resistant strains are assumed. As a result, the coexistence of sensitive and resistant strains leads to the occurrence of consecutive epidemic waves during the disease infection. We employ two main control strategies: prophylaxis and antiviral treatment to study their influences in eradicating or mitigating the outbreak. Then we develop a deterministic model to a SDE form for taking into consideration the stochasticity of drug resistance spread. The basic reproduction numbers and the control reproduction numbers are calculated for the sensitive and resistant strains. Also we discuss the numerical results obtained for the final size of the epidemic from both, the deterministic and stochastic models.

This paper proposes a new method of creating 3D visual data cubes for high volume/dimension OLAP data analysis with intuitive region selection. Previous methods construct data cubes directly from a data warehouse and build table format cubes with multi-dimensional attributes, in order to specify target ranges for analysis. However, it is a difficult task to select appropriate attributes and their ranges from high cardinality of dimensions with hierarchical structure. The new method reduces the number of dimensions according to the levels of relationship, then confines analysis target ranges with intuitive 3D graphical interface to build an analysis target cube.

In literature several correlation filters have been proposed for image recognition. Traditionally linear correlation is applied among the images for this purpose, however, the operation is not robust when images are corrupted with non-Gaussian noise. In this paper we propose the use of morphological correlation combined with nonlinear filters for robust image recognition. Performance of the proposed technique is compared with that of classical linear filtering in terms of discrimination capability. Computer simulation results are provided and discussed.

This paper introduces QC2AS which is a newly designed and developed computer algebra system for symbolic quantum chemical computations. With the rapid advancement of computer, the concern with high-level model chemistry has been growing. To handle such models, it is necessary to manipulate huge algebraic formulas. QC2AS has been designed to handle algebraic formulas appeared in quantum chemistry and it provides an access to our computer algebraic techniques without knowing the background theories. In this paper, we introduce its features and the architecture with some illustrative examples. This is the first report about the development of QC2AS.

A sub-ontology extracted from its base ontology data contains only the concepts and relationships pertaining to the information required by the user. Sub-ontology extraction and sub-ontology tailoring are then viewed as possible solutions to efficiently utilize large-scale ontology data sparsely distributed on a Semantic Grid environment. This shall contribute to reduce the communication overhead in transporting the ontology data, increase the processing performance, improve the reliability in aggregating the required ontology/sub-ontology, and improve the tailoring process of sub-ontology reuse. This paper discussed preliminary experiments as a showcase to illustrate sub ontology extraction and tailoring on a prototype Semantic Grid environment. Functional analysis and discussion of the results are described.
