The Octave Fuzzy Logic Toolkit is an open-source toolkit for Octave that provides a large MATLAB compatible subset of the functionality of the MATLAB Fuzzy Logic Toolbox as well as many extensions. The toolkit includes functions that enable the user to build, modify, and evaluate Fuzzy Inference Systems (FISs) from the command line and from Octave scripts, read/write FISs to/from files, and produce graphical output of both the membership functions and the FIS outputs. Future work will focus on implementing advanced fuzzy inference techniques and GUI tools. The Octave Fuzzy Logic Toolkit is available for download on Octave-Forge and SourceForge.

In wireless sensor networks, there are large numbers of packets in the receiving buffer of sink node. A well designed buffer management could provide efficient packet merging so that it can reduce the number of packets and the transmission overhead. In this paper we present an index table management to manage the receiving buffer for improving packets merging. It can be used in Open WSN. The result of simulation shows that it can reduce the time of processing data as well as the energy costs.

Turbo Code has been claimed as an error correction code that achieves Shannon limit. It has been proposed in many communication systems standards. Performance of Turbo Code under different channel condition is a key factor that should be considered because of requirements of applications. In this paper, we introduced the theory of Turbo Code including a practical Turbo Decoding algorithm - Log-MAP algorithm; we simulated and analyzed the Turbo Code with Log-MAP algorithm under AWGN and fading channels using the open source simulation tool - SCILAB.

Mathematical morphology is a nonlinear filtering method that can be used in noise suppression, feature extraction, edge detection, image segmentation and other image processing problems. Thanks to the powerful ability of matrix computation provided by the OSSC (Open-source Software for Scientific Computation), we can establish a professional mathematical morphology toolbox. During the past years, our team has dedicated to a mathematical morphology toolbox on Scilab called SciMM toolbox. In this paper, we focus on the latest progress of SciMM. A new image segmentation function based on watershed transform is added to SciMM, which is coded with C as a dynamic link library that can be called by Scilab script through the interface function. The toolbox's folder hierarchy is then re-organized according to the newest guideline of making a Scilab toolbox. Some functions are improved for better efficiency, esting results.

A hybrid energy storage with super capacitor and batteries for energy storage unit in wind-pv hybrid streetlight system has been presented. Hybrid energy storage system with super capacitor is given priority to, supplemented by the batter provide adequate, stable and reliable energy guarantee for wind-pv hybrid streetlight system. With this technique a lighter and smaller energy storage system can be achieved which enhances the performance of wind-pv hybrid streetlight system. Super capacitor has drawn more and more attention on energy storage systems because of its advantages of high power density, high charging speed, long service life and small size, light weight and extremely high cycling capability. In this way the batteries can ensure only the average power and the super capacitors can ensure the power variations. When power is greatly change, super capacitors have energy storage buffer action. Storing capacity of super capacitor and variable current control function of parallel controller can reduce times of tiny battery charging and discharging, reduce the discharge depth, prolong the service life of the battery, which basiciy solved the problem of wind-pv hybrid streetlight system. The lifetime of the batteries, weight and volume of the HESS in wind-pv hybrid streetlight can thus been improved. The simulation results verified the validity of proposed control strategy.

Camshift is an effective algorithm for real time dynamic target tracking applications, which only uses color features and is sensitive to illumination and some other environment factors. When similar color existing in the background, traditional Camshift algorithm may fail, that is the target getting lost. To solve the problem, an improved Camshift algorithm is firstly proposed in this paper to reduce the influence of illumination interference. Besides, a method judging whether the target is lost is also proposed. Once the target is judged lost, the Speeded Up Robust Features (SURF) is utilized to find it again and the improved Camshift keeps on tracking the target continuously. SURF is invariant to scale, rotation and translation of images. We program in C++ based on OpenCV. The results prove that the proposed method is more robust than the traditional Camshift and give better tracking performance than some other improved methods.

With the increasing number of host and application to be monitored in the enterprise, the traditional SNMP-based management systems have difficulties to extend and integrate with other applications. WSDM-based host and application monitoring can solve this problem well through web service. In this paper, we design and implement a scalable host and application monitoring framework based on WSDM which maps host's and application's manageability capability to web service. The testing results show that this framework has good scalability and easier integration with other management systems.

The popularity of open-source software is increasing around the world, especially in the field of higher education. Various commercial as well as open-source learning management systems are available today which are being used in educational institutions. These tools have introduced a new concept of teaching methodology which has huge benefits over traditional methods. In this paper, we describe six popular open-source tools and compare them in terms of learning model, functional features, modules, hardware and software requirements. Results of the comparison will help administrators and educators in adoption of learning management system that is most suitable for their needs, and also promote development and usage of open-source learning management systems.
