the programming education is very important in technical colleges, universities and enterprises. We have developed a problem solving environment (PSE) for the education and learning support: TSUNA-TASTE [T. Teramoto, et al., J. Convergence Information Tech., Vol. 5, no. 4, pp. 216-224, 2010]. the TSUNA-TASTE system has a framework to make various programming systems. In this paper we propose and develop a new subsystem of a Procon(Proguraming Contest) Competition Section in Japan. the TSUNA-TASTE may open a new possibility of helpful computer language education.

Mobile devices are fast being realised as tools to facilitate increased interaction among learners and improve engagement with subject material. We report results of a survey of students in their early stages of learning programming, about their perceptions of the use of mobile devices for accessing social networking sites for discussions, chats, brainstorming, and accessing designated learning materials uploaded to support their learning of programming. Students from three universities were surveyed, involving three distinct delivery contexts: traditional face-to-face; blended; and fully online. Our findings include among other things that instant access to discussions, increased interactions, instant feedback in a student-student context, and the ability to share ideas and views anytime, anywhere, were just some of the perceived advantages of using mobile devices and social networking sites for learning programming.

Traditional description methods of RNA secondary structure could lead higher complexity of time in RNA structure comparison. this article offers a vector method of describing RNA secondary structure. then, we compare RNA secondary structures tree by dynamic programming and those structures come from NA segments of highly pathogenic H5N1 virus. It is superior to the method of minimum free energy on time complexity. And it shows RNAs hold higher similar structure when they hold stronger pathogenicity, which could be a good guide for biological experiments.

this paper presents a novel approach to mobile robot exploration. In this approach, mobile robots send their local maps to the central controller and coordinate with each other using a wireless sensor network (WSN). Different from existing rendezvous point-based exploration strategies, the use of a WSN as the communication media allows quick and cost-effective exploration and mapping of an unknown environment. Overall, this paper introduces WSN-aided mobile robot exploration strategy and shows comparative performance evaluations using the Player/Stage simulation platform. Here, our main goal is to present potential advantages of WSN-aided mobile robot exploration for Simultaneous Localization and Mapping (SLAM).

Adopting classic redundancy-based fault-tolerant schemes in highly dynamic distributed computing systems does not necessarily result in the anticipated improvement in dependability. this primarily stems from statically predefined redundancy configurations employed within many classic dependability strategies, which as well known may negatively impact the schemes' overall effectiveness. In this paper, a novel dependability strategy is introduced encompassing advanced redundancy management, aiming to autonomously tune its internal configuration in function of disturbances observed. Policies for parsimonious resource allocation are presented thereafter, intent upon increasing the scheme's cost effectiveness without breaching its availability objective. Our experimentation suggests that the suggested solution can achieve a substantial improvement in availability, compared to traditional, static redundancy strategies, and that tuning the adopted degree of redundancy to the actual observed disturbances allows unnecessary resource expenditure to be reduced, therefore enhancing cost-effectiveness.

We consider the problem of finding (possibly non connected) discrete surfaces spanning a finite set of discrete boundary curves in the three-dimensional space and minimizing (globally) a discrete energy involving mean curvature. Although we consider a fairly general class of energies, our main focus is on the Willmore energy, i.e. the total squared mean curvature. Most works in the literature have been devoted to the approximation of a surface evolving by the Willmore flow and, in particular, to the approximation of the so-called Willmore surfaces, i.e., the critical points of the Willmore energy. Our purpose is to address the delicate task of approximating global minimizers of the energy under boundary constraints. the main contribution of this work is to translate the nonlinear boundary value problem into an integer linear program, using a natural formulation involving pairs of elementary triangles chosen in a pre-specified dictionary and allowing self-intersection. the reason for such strategy is the well-known existence of algorithms that can compute global minimizers of a large class of linear optimization problems, however at a significant computational and memory cost. the case of integer linear programming is particularly delicate and usual strategies consist in relaxing the integral constraint x ∈ {0,1} into x ∈ [0,1] which is easier to handle. Our work focuses essentially on the connection between the integer linear program and its relaxation. We prove that: One cannot guarantee the total unimodularity of the constraint matrix, which is a sufficient condition for the global solution of the relaxed linear program to be always integral, and therefore to be a solution of the integer program as well;Furthermore, there are actually experimental evidences that, in some cases, solving the relaxed problem yields a fractional solution. these facts indicate that the problem cannot be tackled with classical linear programming solvers, but only with pure integer linea
