It is vital that our curriculum motivates and inspires the scientists of the future. With careful planning and a measure of rigor, integrated learning can be particularly motivating. Bringing subjects together to address a problem that students see as 'real' can excite them. Virtual Reality(VR) offers teachers and students unique experiences that are consistent with successful instructional strategies: handson learning, group projects and discussions, field trips, simulations, and concept visualization. Within the limits of system functionality, we can create anything imaginable and then become part of *** VR learning environment is experiential and intuitive;it is a shared information context that offers unique interactivity and can be configured for individual learning and performance *** Universiti Malaysia Pahang, we use EON Creator to embed VR in primary school education to increase the understanding of science concept.

The performance of Ad hoc routing protocol always has been measured by using free-space model and Two-ray ground model. But these two models are very simple and can't represent real world propagation, because they ignored the effect of obstacles in their environment representation. So the most real models is shadowing propagation model which has taken all these factors in account. This paper explains the effect of using two types of propagation models which are: Two Ray Ground model and shadowing model for two important protocols such as Destination Sequenced Distance Vector (DSDV) and Optimized Link Status Routing (OLSR), which are considered a proactive and Table Driven routing protocols and then different performance metrics has been measured. The simulations results have shown that the type of the propagation model has great impact on routing protocol, and it has effected severely on its performance.

software products are getting increasingly complex described by a large number of requirements that characterize the user needs. In most cases, not all requirements can usually be met with available time and resource constraints; therefore, taking correct decisions about which requirements to implement in a release is crucial as the wrong decision from requirements engineers results in implementation of the false requirements, which lead to failure of project or product in the market. Although much research is done on requirements prioritization techniques, but studies in the area pointed out that when investigating the research made within the area, there seems to be little evidence regarding which approach is better than others and in what situations and environments. This paper presents an initial design of a controlled experiment to compare three prioritization methods. The goal of this experiment is to investigate which technique is better in terms of time consumption, accuracy, and ease of use. The experiment will be conducted in an academic context in Malaysian university.

The paper discusses the methodology of Domain-Specific Mathematical Modelling, allowing development of metamodels and their application to modelling domains with different mathematical structure. The concepts of the metamodel, the metamodelling, the domain are considered, the stages of Domain-Specific Mathematical Modelling and the architecture of implementing this methodology software tools are defined.

The new approach to development of Domain Specific Languages (DSL) for solving tasks of systemsengineering (SE) is proposed. A DSL alphabet is defined on the base of an ontology of the SE domain as the set of its typical concepts. A DSL grammar on the base of Finite State Machine (FSM) formalism is defined, which allows to link the SE ontology with the different SE processes (specification of requirements, work planning, development, validation, standardisation etc.). A DSL is mapped with the set of mathematical methods, which allows to solve arising in the SE domains tasks. The approach on the sample of development of the DSL for specification of requirements is illustrated.

The new approach to development of metamodels for domain specific modelling is proposed in the paper. The logical system for expressing domain specific knowledge is linked with an algebraic structure, defined at the meta-metamodel level. This allows to take into account the mathematical structure of modelled domains, and to use algebraic operations for development of new effective methods for solving domain specific tasks. The applicability of the approach for development of the metamodel “Vector Logic” is shown. Vector logic is a diagrammatic system of propositional logic in which propositions are vectors in the logical space. Practical implementation of the metamodel in the Vector Logic Visual 3D Environment is considered.

Information systems supporting flexible business in small-to-medium enterprises must be easily modifiable under the supervision of their users. The users (business people) must take active part in agile system development and maintenance. The systems must be able to integrate large legacy systems and to communicate with the systems of independent business partners. Business processes need not be executed by a single ERP. We discuss a variant of SOA able to meet these requirements. The discussed SOA uses communication protocols based on problem-oriented languages. We propose a concept of organizational (architectural) services generalizing the concept of connectors and routers. The power and usefulness of the proposal is demonstrated on the examples of service composition, business-oriented interfaces, agile business processes, portals, and gateways. The proposal is based on experience from practical SOA projects.

With the advancement of technology in communication network, it facilitated digital medical images transmitted to healthcare professional via internal network or public network (e.g. Internet). Consequently, digital medical image security has become an important issue when images and their pertinent patient information are exposed to the threats, such as tampering of images to include false data which may lead to wrong diagnosis and treatment. Medical image distortion is not to be tolerated for diagnosis purposes, thus a reversible watermarking is introduced. This paper reviews the works that have done on the reversible watermarking scheme with tamper localization and recovery capability.

The paper considers computer-Aided Design (CAD) system FORTU-FEM, which mathematical base is the Finite-Element Method (FEM). Unlike other CAD systems, which does not allow to their users to change the schema of calculation, FORTU-FEM has an open architecture and allows to engineers to develop various methods for design and analysis of non-standard mechanical constructions. Applications of FORTU-FEM for design of non-standard constructions from elastomers, calculation of the tensional and the deformed states of such the constructions are considered.
