Cloud computing is becoming a popular solution for storing data and executing applications, where task dispatching in the scheduling policy is significant to the overall performance in the Cloud systems. To minimize the makespan of the application consisting of many independent tasks, a heuristic task dispatching algorithm is proposed in this paper. Therein, the task is dispatched to the virtual machine with the least relative workload. Then combined with the local schedule strategy of the virtual machine, the performance of the task dispatching algorithm is analyzed and simulated in CloudSim, which indicate that the proposed algorithm can improve the performance of the clouds.

In recent years, the near-infrared spectroscopy measurement technology in China has made considerable progress;it has been widely used in the fields of agriculture, chemistry, geology, and medicine measurement. The nearinfrared spectroscopy is very sensitive to the characteristics of CH(methyl, a methylene group, a methoxy group, a carboxyl group, an aryl group, etc.), hydroxy O-H, mercapto S-H, and amino N-H. So, it can distinguish the crystallinity of single mineral(clay minerals, chlorite, serpentine, etc.), containing hydroxy silicate minerals(epidote, amphibole, etc.), sulfate minerals(alunite, pyritepotassium alum, gypsum, etc.), and carbonate minerals(calcite, dolomite, etc.) in the layered silicate. The character of near-infrared spectroscopy is one of the important guarantees for the instrument development of the small portable near-infrared mineral analyzer, and for its fast, accurate identification of rock samples. In this paper, we focus on the near-infrared spectral characteristics, identification method, and quantitative analysis method for the low-temperature alteration minerals;at the same time, a portable near infrared spectrometer and its principle were presented. In the experiment, spectral parameters were acquired from the characteristic spectra of altered minerals, and the relationship between altered minerals and ore-forming were established. The measured spectral data from the drilling rock cores in Zijinshan Mine in Fujian province was used as an example to illustrate the credibility of the proposed method.

The full polarimetric information of the target from polarized Synthetic Aperture Radar (POLSAR) enables us to implement recognition and classification of remote sensing images more effectively. Based on the analysis of typical polarized target decomposition and classification, the issue proposes a new scheme for iterative classification of polarimetric SAR image, which blends the outcomes of Yamaguchi decomposition and H/α decomposition. This technique extracts four decomposition coefficients of four scattering mechanism components through Yamaguchi decomposition, the scattering entropy and angle through H/α decomposition first;then the initial classification of the POLSAR images is done by the combination of the 6 parameters mentioned above. The final result is obtained by iterative classification due to coherence scattering matrix following wishart distribution. The effectiveness of this method plus less computation required is demonstrated by the experimental results of polarimetric SAR data. ©2010 ieee.

Mobile Edge computing (MEC) provides mobile and cloud computing capabilities within the access network, and aims to unite the telco and IT at the mobile network edge. This paper presents an investigation on the progress of MEC, and proposes a platform, named WiCloud, to provide edge networking, proximate computing and data acquisition for innovative services. Furthermore, the open challenges that must be addressed before the commercial deployment of MEC are discussed.

SERVQUAL model has been used to measure service quality in different industries. In most cases, this model was validated by confirmatory factor analysis approach. The objective of this research is to validate SERVQUAL model with higher order factor analysis approach to find whether or not there is a second-order component of service quality in the context of information system use. For this objective, an empirical study is proceeded to validate one IS-adapted SERVQUAL model in the context of an e-learning system use. Results under higher order factor analysis approach reveal good fitness and effectiveness, which will provide support for the future research on relationships among affected factors with service quality. ©2010 ieee.

Protein is an important molecule that performs a wide range of functions in biological systems. The GOR algorithm is one of the most successful computational methods to predict secondary structure from protein sequence. FPGA chips have emerged as one promising application accelerator to accelerate bioinformatics algorithms by exploiting fine-grained custom design. In this paper, we propose a complete fine-grained parallel hardware implementation on FPGA XC5VLX330 chip to accelerate the GOR IV package for protein secondary structure prediction. The experimental results show a speedup factor of more than 430x over the GOR-IV software version running on a PC platform with AMD Phenom 9650 Quad CPU for 2-Dimensional protein structure prediction. However, the power consumption is only about 30% of that of current general-purpose CPUs. ©2010 ieee.

Most Web browsers are designed for visual interaction, which receive input and render webpage content via a graphical and visual mode. For people with visual disabilities, access to the Web is very difficult. In this paper, we propose a new scheme of non-visual browser, which is referred to as Multi-Channel Speech Pushing System (MCSPS). The system can support browsing from both PC client and telephone users, avoiding construction of two individual systems. Furthermore, by web page content and structure analysis and reorganization, the system can help user locate desired information efficiently. Compared with current non-visual browsers, the proposed system performs deeper and more thorough analysis and reorganization of web pages, thus resulting in higher efficiency in browsing. ©2010 ieee.

Energy minimization is often the key point of solving problems in computer *** decades,many methods have been proposed(deterministic,stochastic,…).Some can only reach local minimum and others strong local minimum close to the optimal solution(global minimum).Since beginning of 21th century,minimization based on Graph theory have been generalized to find global minimum of multi-labeling problems. In this work,we study deterministic local minimization methods (Iterative Conditional Modes and Direct Descent Energy),and a stochastic global minimization with an improved Simulated Annealing algorithm.A new approach formulation to help local minimization to converge to a minimum closed to the global one is *** method combines local and global energy constraints in an multiresolution *** focus on stereo matching *** improved Simulated Annealing proved to reach global minimum as good as Graph based minimization methods. Promising results of proposed local minimization methods are obtained on Middlebury Stereo database compare to global methods.

In 2008, Lotfi Zadeh concluded that to make significant progress toward achievement of human level machine intelligence a paradigm shift is needed. In previous papers we introduced the computational information conservation theory (CICT) approach to get more effective and reliable cognitive, biophysical, and biomedical engineering simulation solutions. CICT new computational information conservation awareness can open the way for a paradigm shift to recover lost coherence information in system description and to develop even advanced quantum cognitive systems. To achieve this result, in present paper, we show the fundamental pre-spatial geometro-arithmetic scheme defining optimized numeric word generators and relations to minimize the traditional multiscale statistic modeling veil opacity and information entropy generation. It is the first, fundamental step to an effective progression from computing with numbers to computing with numeric words with precisation of their meaning. This paper is a relevant contribution towards an effective and convenient "Science 2.0" universal computational framework to achieve deeper cognitive intelligence at your fingertips and beyond.
