The barrier free transplantation of software is critical to the development of intelligent software. On different software platform, there are great differences between the software interfaces and the communication protocols, resulted in software cannot be directly transplanted on different platform. Once the platform is different, the differences of software characteristic are big, and the software compatibility will become worse rapidly. The incompatibility problem is occurred in the transplantation process, the effective software transplantation cannot be completed.

Tri-training learning is a widely used semi-supervised classification method that addresses the problem of lacking of labeled examples. In this paper, a novel semi-supervised learning algorithm based on tri-training method is proposed. The proposed algorithm combines margin sampling (MS) technique and differential evolution (DE) algorithm to select the most informative samples and perturb them randomly. Then the samples we obtained, which can fulfill the labeled data distribution and introduce diversity to multiple classifiers, are added to training set to train base classifiers for tri-training. The proposed algorithm is experimentally validated using real hyperspectral data sets, indicating that the combination of MS and DE can significantly reduce the need of labeled samples while achieving high accuracy compared with state-of-the-art algorithms.

Published: December 2014

Dynamical properties of mechanical systems can be obtained with the vibration signals from the systems. However, for the influence of noises, it is difficult to accurately acquire the features. Therefore, de-noising operation is significant for vibration signal in the practical engineering. In order to resolve this problem, the Ensemble Empirical Mode Decomposition (EEMD) method is introduced to try to eliminate noises from the analyzed signal. At first, the theory of the method is illustrated, which included adding white noises, EMD for the signal and calculating the mean of the intrinsic mode function. On this base, the signal which contains several harmonic components with white noise is processed by EEMD. As the result shown, the random noise can be effectively removed; moreover, the harmonic components can be accurately separated. And these improve that the EEMD is an effective method for the de-noising.

Published: December 2014

Time series analysis has been extensively used in many fields, such as system identification, modeling and data predication, and played an important role in system design, planning and performance analysis. The focus of time series application study is how to improve the accuracy and computation speed of the parameter estimation. Many researchers have carried out system modeling study by applying time series analysis and have gained their research results.

Comparison of memory polynomial model and ADS simulation of MRF21085 amplifier demonstrate memory polynomial model can represent the electric characteristic of it exactly.

Authors: Huang Yao , Li Ji Ping
Published: December 2014

We develop a reduced-complexity approach to the detection of SOQPSK-TG, a highly bandwidth-efficient constant-envelope waveform. The optimal detector for SOQPSK-TG requires of a bank of 2784 matched filters and 512 states, which is impractical and highly complex. In this paper, a practical detector was developed based on Laurent decomposition and frequency pulse truncation (PT) technology, with the number of correlators reduced to only 2 and states reduced to 4 at the expanse of less than 0.2dB at BER of 10-4.

For dynamical changed network topology and unstable links, this paper proposes a mobility prediction-based weighted clustering algorithm for vehicular ad-hoc network with high mobility nodes. In the CH election stage, it computes vehicle’s priority through the similarity, intimacy and centrality, the vehicles with the highest priority in their neighborhoods are selected as the CHs, this scheme suitable for large scale network. NS2 simulation results show that the proposed clustering scheme improves the stability of cluster structure, prolongs the CH duration time, improves the delivery ratio.

Authors: Qi Ben Sheng , Shi Jun Juan
Published: December 2014

In this paper, a low-cost compact monopole UWB antenna with variable band notch characteristics is presented. The antenna is complemented on FR4 substrate with the whole size of . And the proposed antenna consists of a radiating patch with two symmetric semiellipse parasitic patches. A U-shaped slot is added to achieve a desired band notch frequency. It is excited by a 50 microstrip-line feed. A partial trapezoid ground plane with two symmetric L-shaped slots and two parasitic patches both can help to obtain higher frequency bandwidth more than 139% (2.8 GHz~15.6 GHz). The substrate with two circular holes can slightly improve the lower frequency characteristic. The simulation of the proposed antenna is achieved by CST Microwave Studio Software.

Dynamic RWA algorithm which supports differentiating business service quality levels becomes a hot research in optical networks. This paper proposes a better ant colony algorithm for routing and wavelength assignment in ASON with supporting differentiating SLA of services and 10P bps network capacity. Firstly, the algorithm adds the concept of business interval period M to dynamically adjust the wavelength grouped in different periods So as to better meet the sercice requests of different levels; Secondly the algorithm adds a link selection control factor in the transition probability function ACA in order to achieve a better link load balancing. Simulation results show that after joining the cyclical and link selection control factor, blocking rate becomes lower and the load of network becomes more evenly.
