Calcium ions(Ca) are crucial for protein *** participate in enzyme catalysis,play regulatory roles,and help maintain protein *** recognizing Ca-binding sites is of significant importance for protein function *** much progress has been made,challenges remain,especially in the post-genome era where large volume of proteins without being functional annotated are quickly *** this study,we design a new ab initio predictor,CaSite,to identify Ca-binding residues from protein *** first uses evolutionary information,predicted secondary structure,predicted solvent accessibility,and Jensen-Shannon divergence information to represent each residue sample feature.A mean ensemble classifier constructed based on support vector machines(SVM) from multiple random under-samplings is used as the final prediction model,which is effective for relieving the negative influence of the imbalance phenomenon between positive and negative training *** results demonstrate that the proposed CaSite achieves a better prediction performance and outperforms the existing sequence-based predictor,TargetS.

With the popularity of mobile smart devices, location-based services have been more widely used. Bichromatic Reverse k Nearest Neighbor(BRkNN) queries have become a hotspot in spatial-textual databases domain. In this paper, we extend the concept of traditional BRkNN method to process the object with multi-level tags in some specific scenes, and we propose a new type of query, called Maximized Bichromatic Reverse k Nearest Neighbor with Multi-Level Tags queries(MaxBRkNN-MLT), to find the optimal position of object with multi-level tags in the spatial-textual database. Unlike traditional methods, the number of the results of the MaxBRkNN-MLT query is maximized, which can cross the great divide between space and text. The query method proposed in this paper has a wide range of application scenes. For example, in the advertising industry, advertisers expect to find an optimal position, so that the ads with a given tag can attract the most users. Finally, experiments show that the MLT method has better query precision and execution efficiency than the baseline approach.

E-commerce has been one critical component of information society now;however credit is becoming a bottleneck for its further development. Therefore Shanghai is building a third-party e-commerce credit evaluation platform. The platform will be integrated with many external systems to collect massive credit-related data, do scientific evaluation and provide users with personalized credit services. In order to deal with mass data and provide personalized services to tenants of the platform, a cloud computing model of Shanghai e-commerce credit evaluation platform is designed in this paper. In PaaS layer, we propose a mass data processing technology based on the XML metadata specification;in SaaS layer, we propose a mixed model of data storage and a model of areas-layered tenant customization. Experiments show that these technologies and models can improve the data processing efficiency and resource utilization greatly.

This research-in-progress proposes an approach that accounts for social and institutional issues in the design and implementation of sensor networks for air-quality monitoring. The proposed approach is evaluated through action research, in an initiative that seeks to enhance the air-quality sensor network of a Megalopolis based on data analytics. Preliminary findings indicate that the proposed approach improves access to resources, enhances the validity of design, and increases buy-in for implementation.

The alternating group graph, denoted by AG(n) , is one of the popular interconnection networks. In this paper, we consider two network connectivities, H-structure-connectivity and H-substructure-connectivity, which are new measures for a network's reliability and fault-tolerability. We say that a set F of connected subgraphs of G is a subgraph-cut of G if G-V (F) is a disconnected or trivial graph. Let H be a connected subgraph of G. Then F is an H-structure-cut, if F is a subgraph-cut, and every element in F is isomorphic to H. And F is an H-substructure-cut if F is a subgraph-cut, such that every element in F is isomorphic to a connected subgraph of H. The H-structure-connectivity(resp. H-substructure-connectivity) of G, denoted by is an element of(G;H)(resp. is an element of s (G;H)), is the minimum cardinality of all H-structure-cuts(resp. H-substructure-cuts) of G. In this paper, we will establish both is an element of(AG(n);H) and is an element of(AG(n);H) for the alternating group graph AG(n) and H is an element of{K-1 ,K-1,K-1 ,K-1,K-2 }.

This paper presents about Combined Cycle Power Plant(CCPP) and decision tree. CCPP considered as the best effective power suppliers to the large temperature incline between its gas turbine passage and the environment or the cooling process, and to help of their engineers, who are able to optimally venture the present temperature level. Moreover, in this paper we did comparison of four types of decision tree algorithms like Decision Stump, Hoeffding Tree,logistic model trees(LMT) and J48. Based on these algorithms we analyzed the behavior of Combined Cycle Power Plant(CCPP), particularly its temperature. The temperature is target variable among other variables. This is why temperature was divided three classes. Theoretical analysis and experimental results have shown that the J48 algorithm is the best algorithm which predict attributes of given instances precisely among other three algorithms. Based on our findings, J48 algorithm can predict precisely the temperature of Combined Cycle Power Plant and predict 97.1676% cases correctly.

As the size of the transistor continues to shrink, a number of reliability issues have emerged in network-on-chip(NoC) design. Taking into account the performance degradation induced by Negative Bias Temperature Instability(NBTI) aging effect, this paper proposes an aging-aware task scheduling framework for No Cbased multi-core systems. This framework relies on a NBTI aging model to evaluate the degradation of core's operating frequency to establish the task scheduling model under aging effect. Then, we develop a particle swarm optimization(PSO)-based heuristic to solve the scheduling problem with an optimization objective of total task completion time, and finally obtain a scheduling result with higher efficiency compared with traditional scheduling algorithms without considering of NBTI aging effect. Experiments show that the proposed aging-aware task-scheduling algorithm achieves not only shorter makespan and higher throughput, but also better reliability over non-aging-aware ones.

This The system marginal price reflects the shortterm supply and demand of electricity goods in the electricity market, which is an important economic link to the participating members of the market. The traditional prediction model has a large error and low generalization ability to forecast the shortterm marginal price. Therefore, this paper proposes an ensemble learning algorithm for short-term marginal price forecasting based on Ada Boost. In this paper, the main factors influencing the short-term marginal electricity price are analyzed. Based on the Ada Boost algorithm, the short-term marginal electricity price forecasting problem is modeled. Four prediction models(C4.5, CART, Linear neural network, BP) are compared, and a short-term marginal price forecasting algorithm is proposed. By comparing the actual values with the predicted values, our proposed algorithm is superior to SVM and BP algorithm, which has high application values in power plant engineering.
