S3Computing requires distributed computing performed by social network platform has high scalability and security. Protocol models meeting the requirements of S3Computing not only ensure the correctness and robustness of distributed computing, but also reduce risks introduced by involvement of nodes with low reputation in computing. These models safeguard the data collections and computations performed on platform of teacher’s learning community for social researches. This paper constructs a protocol model entitled LC which adapts platform of teacher’s learning community and meets the requirements of S3 Computing. This protocol model is the key step of implementing distributed computations on learning community platform. © 2016 SERSC.

Automated visual inspection of fabric defects is a challenge due to the diversity of the fabric patterns and defects. Although there are many automated inspection methods of identifying fabric defects, most methods process images containing the fabric patterns classified as the crystallographic group p1 and implicitly assume the fabric patterns are arranged in fixed directions. This paper proposes an automated defect inspection method which calibrates the fabric image and then segments the image into none-overlapped sub-images which are called lattices. Thus, the image is represented by hundreds of lattices sharing some common features instead of millions of unrelated pixels. The defect inspection problem is transformed to comparing the lattice similarity based on the shared features and identifying the defective lattices as the outliers in the feature space. The performance of the proposed method ILS (Isotropic Lattice Segmentation) is evaluated on the databases of images containing fabric patterns arranged orthogonally and arbitrarily. By comparing the resultant images with ground-truth images, an overall detection rate of 0.955 is achieved, which is comparable with the state-of-the-art methods. © 2017 The Franklin Institute.

In this study, based on the consideration of energy consumption, we take to improve the strategy of the MapReduce job scheduling algorithm, in order to reduce the average response time for task scheduling of interactive jobs in the network. In accordance with the job priority grouping to adjust the scheduling task response time which can reduce the impact of network congestion, with good results that increase the throughput of the system transferring data and computing power. © Maxwell Scientific Organization, 2013.

This paper discusses how anodic pulses and periodic current reversion influence electrodeposition. Depending on the involved metal and electrolyte, very different effects can be observed and taken advantage of. The Wagner number, Wa, describing the current distribution is shown to be useful for predicting the throwing power at low frequencies of current reversion, even in complex electrochemical systems, but is less useful at higher frequencies. Passivation can occur due to oxide formation, super-saturation of metal salts or depletion of complexing agents at the electrode surface. Furthermore, dissolution and desorption processes in the anodic period can have strong influence on the succeeding cathodic electrocrystallisation affecting preferred crystal orientation, intrinsic stress and current efficiency. A literature survey is combined with experiments from silver plating from a cyanide bath. © 2014 Institute of Materials Finishing Published by Maney on behalf of the Institute.

This paper focuses on finding minimal complexities of decision trees representing rules defined for features and functionalities of online learning community. Because simultaneously minimizing all complexities is not always possible and this matches pattern of multiobjective optimization, Pareto optimal point is introduced for describing complexity distributions for selecting decision tree most suitable for system requirements. Unlike typical multiobjective optimization whose feasible space can be explicitly represented, feasible space for complexities of decision trees can only be implicitly reflected by relationships of subtables and associated objective functions due to the great number of possible trees. This paper provides a means of finding Pareto optimal points in implicit feasible space determined by objective functions defined for describing decision tree complexities by using graph and associated algorithm. The experimental results show that proposed algorithm yields valid results for finding Pareto optimal points. Copyright © 2015, AIDIC Servizi S.r.l.

The biggest characteristic of LogGP model based on LogP mode is sending long messages, if all the elements to be sent are seem as a long message and sent in a single processor, a sorting algorithm should be introduced to merge those elements, but the algorithm designed in the LogP mode is heavily dependent on the accuracy of parameters such as l, o, g, p. However, parameters are often inaccurate in reality. This may lead to message traffic congestion in the transfer process and the degradation of Communication performance of system. Therefore, this study proposes a new algorithm, that is, synchronization barrier is introduced into PSRS algorithm, which can improve LogGP Model further. Network congestion will be avoided when sending a long message and system performance will be improved.The barrier synchronization method can be applied to other algorithms of LogGP model, so it has a certain practicality. © Maxwell Scientific Organization, 2013.
