The exponential decrease in the quality of education despite innumerable number of learning systems has motivated us to design learning environments that ensure quality of education. We propose GAMBLE as a goal driven model based approach to teaching/learning that emphasizes on making goals of learners and instructors explicit and provides a platform for designing, refining and debugging models to achieve these goals. We also propose the idea of SPLEAN that integrates lean thinking and software product lines to significantly improve productivity. This paper also discusses construction of eLearning Systems that are of broader interest to society like adult literacy as a means of evaluating proposed approaches and ends with many possible future directions towards ensuring quality of education.

To reduce the redundant information in software static analysis and improve the accuracy and efficiency of the information extraction, this paper proposed a syntax trees model based on relational storage mode. Modeling on dependency relationship between terminals will effectively reduce the information redundancy and can be stored in XML(eX tensible Markup Language) format. Using the mature XML parsing technique, a new static detection method based on XML model is put forward and applied to program norm. Experimental results show that: the method not only improves the detection efficiency but also increases the detection accuracy.

The ground states of some many-body quantum systems can serve as resource states for the one-way quantum computing model, achieving the full power of quantum computation. Such resource states are found, for example, in spin-52 and spin-32 systems. It is, of course, desirable to have a natural resource state in a spin-12, that is, qubit system. Here, we give a negative answer to this question for frustration-free systems with two-body interactions. In fact, it is shown to be impossible for any genuinely entangled qubit state to be a nondegenerate ground state of any two-body frustration-free Hamiltonian. What is more, we also prove that every spin-12 frustration-free Hamiltonian with two-body interaction always has a ground state that is a product of single- or two-qubit states. In other words, there cannot be any interesting entanglement features in the ground state of such a qubit Hamiltonian.

Spam detection is a significant problem which considered by many researchers by various developed strategies. Among many others, simple artificial immune system is one of those being proposed. There is a deficiency in number of optimization methods in simple artificial immune system (SAIS). This problem can be solved and eliminated using other optimization methods besides mutation. In this research, SAIS was hybridized by particle swarm optimization (PSO) for optimizing the performance of SAIS for spam filtering. PSO was used with mutation to reinforce the immune system's searches to find the best class in exemplar for classification. Achieved results represent the Hybrid SAIS and PSO is superior to that of a SAIS.

Virtual view rendering is one of the key technologies to realize Three-Dimensional Television (3DTV) system, but which still exists, such as false contour, holes and other issues. In this paper, these problems are been effective solved. First, we use the connection of pixel coordinate warping between reference image and virtual image in the rendering process, to make quick decision on the position of hole region and its edge and then utilize the way of outward expanding the edge of holes to cover residual or warping error pixels; then eliminate false contour by image synthesis with the left and right view images from rendering based on the location of holes; finally, we use mean filter and the image restoration method of total variation model to fill holes. The experimental results show that the proposed method improves the quality of virtual view images from rendering.
