Protein structures are essential to understand the function. The predicted models have a broad range of the accuracy. Reliable estimates of the model quality are critical in determining the usefulness of the model to address a specific problem. In this study, a novel method has been presented to rank the models by their relative qualities. The proposed method first extracts various features from the three dimensional structures of proteins and then the learning-to-rank algorithm is used to rank the models based on their similarities with the native structures. Furthermore, a quasi single-model method is presented, which uses the top five identified models as references and ranks the other models by the average similarity with the reference models. Benchmark test is performed on a newly developed, template-based decoy generators which covers all the main structure classes of proteins. The proposed learning-to-rank method achieves an average Pearson correlation coefficient of 0.94 and a AUC value of 0.97, which consistently outperform all other well-developed methods. The quasi single-model can further improves the performance and achieve nearly perfect results with both PCC and AUC value of 0.99. The results demonstrate that the proposed method is an effective methodology for model quality assessment and provides the state-of-the-art performance.

While TRIZ is increasingly developing both in research and education, users always encounter difficulties in their attempts to practice it, especially for one of the most complicated inventive problem solving tools, the Su-Field analysis, which is used to analyze and improve the efficiency of a technical system. Generally, the process of using a Su-Field model to solve a specific inventive problem includes: building a Problem Model, mapping it to a Generic Problem Model, finding a Generic Solution Model based on the corresponding inventive standard and finally establishing and interpreting a Solution Model in real life. As one of the most important phases of the Su-Field analysis, the last step is normally implemented manually with the help of the pointers to physical effects, which link generic technical functions to specific applications and systems. The adequate pointer, compatible with the context of the specific problem, should be chosen to assist the users to instantiate the Solution Model. However, the pointers to physical effects and the specific problems are built at different levels of abstraction, so it is difficult for the users to choose among many eligible pointers to physical effects given a certain function. This paper proposes a heuristic method to use the pointers to physical effects based on ontology reasoning. The use of formal models, called ontologies, allows to formally define the concepts about the models and the effects and to apply logical reasoning on them. An inventive standards ontology and a physical effects ontology are firstly built to describe the process of Su- Field analysis, and then the logical reasoning rules are established according to a lexical dictionary, the analysis of the inventive standards and the physical effects. The lexical dictionary, based on WordNet, is built to improve the selection of the appropriate effect to apply. Finally, ontology reasoning is implemented to provide heuristic physical effects for the users.

While TRIZ is increasingly developing both in research and education, new users always encounter difficulties in their first attempts to practice it. In such situation, Altshuller's original matrix often appears as an “easy-to-begin- with” tool. However, while not being representative of what TRIZ really is, it continues to seduce new users, teachers and trainers. Several approaches to automate the use of the contradiction matrix have been proposed in literature, and researches on the automatic match between specific parameters of the artefact being considered and Altshuller's generalized parameters remains a topic of interest. In this paper, we propose a way to automate the proposal of equivalencies between a specific parameter and a generic parameter from the matrix. This method calculates the semantic distance between short texts, and uses it to fill the semantic gap between the specific parameters of the artefact and the generalized ones. Case-based reasoning is also used to improve the whole accuracy of the method.

Su-Field analysis, as one of the inventive problem solving tools, can be used to analyse and improve the efficacy of the technical system. Generally, the process of using Su-Field model to solve a specific inventive problem includes: building a Problem Model, mapping to a Generic Problem Model, finding a Generic Solution Model based on the corresponding inventive standard, and finally establishing and instantiating a Solution Model. As one of the most important phases of Su-Field analysis, the last step is normally implemented manually with the help of physical effects, which link generic technical functions with specific applications and systems. The physical effects compatible with the context of the specific problem should be chosen to assist the users to instantiate the Solution Model. However, the physical effects and the specific problems are built at different levels of abstraction, and it is difficult for the users to choose, that is, given a certain function, too many physical effects are chosen while with the detailed context of the problem, no physical effect is returned. This paper firstly proposes a new way of representing physical effects using the change of two states, that is, the couple of two states before and after applying physical effects. Then, the knowledge about using physical effects is formalized in OWL (Ontology Web Language) - an ontology language for semantic web, and the constraint knowledge, such as the condition to use each kind of physical effect, is formalized in SWRL (Semantic Web Rule Language) - a rule language. Finally, the reasoning process of using physical effects is performed with the support of JESS (Java Expert System Shell) rule engine.

Considering that VANET may reflect the characters of opportunity network, a routing scenario with real-time information perceiving is proposed in this paper. First, a node executes limited and directed data flooding and then carries out feedback with modified greedy algorithm using hot area. In this strategy, nodes dynamically adjust parameters by self-learning properly. The experiment result under ONE simulator shows its promotion comparing to classic Epidemic, etc. © 2014 Springer-Verlag Berlin Heidelberg.

Content distribution schemes for Video on Demand (VoD) systems, based on the peer-to-peer (P2P) technology, have attracted more and more attention. Recently, people mainly focus on the latency performance, security, interaction, scalability, and so on. We propose a new network topology model - Similarity Crossed Cube(S-CQ for short), which combines with the feature of crossed cube and establishes multiple independent spanning trees for data distribution in the layer. This network model processes the properties such as good self-organization, delay, etc. The simulation results also show that it can effectively reduce the playback delay and maintain a low delay. The S-CQ network model can provide good quality of VoD service and effectively improve the user experience.

LBlock is a 64-bit lightweight block cipher which can be implemented in both hardware environments and software platforms. It was proposed by Wu Wenling and Zhang Lei at ACNS2011. We studied the security of LBlock found that the permutation layer can getting better on security in the internet of things. In order to assure it can achieve enough security, we gave an improvement on permutation layer of LBlock. By analyzing the property of the diffusion transformation, it has shown that a new kind of 11-round impossible differential was presented. To the best of our knowledge, this is the first paper that proposes this way analysis on improved LBlock. © Springer Science+Business Media Dordrecht 2014.

Image classification is a well-known classical problem in multimedia content analysis. In this paper a framework of semi-supervised image classification method is presented based on random feature subspace. Firstly, color spatial distribution entropy is introduced to represent the color spatial information, and texture feature are extracted by using Gabor filter. Then random subspaces of the feature vector are dynamically generated from mixed feature vector as different views. Finally, three classifiers are trained by the classified images and tri-training algorithm is applied to classify sample images. Experimental results strongly demonstrate the effectiveness and robustness of the proposed system. © Springer-Verlag Berlin Heidelberg 2014.

An efficient and inexpensive dependent task scheduling algorithm is proposed in this paper which is based on a Directed Acyclic Graph. Firstly, the task prioritizes estimates from bottom to top. Secondly, top-bottom task priority estimate is based on the results of the first estimate;while adding a priority to be more explicit of the estimates of the tasked priority, the key tasks can be performed as early as possible and can effectively shorten a scheduling length while optimizing the dependent tasks execution costs in the cloud. Experimental results show compared algorithms of HEFT. CPOP, and DPS with OADTS. It increased by 10 % in terms of time efficiency and the execution costs decreased by 7%, which is an efficient and inexpensive scheduling method for dependent tasks in the cloud environment. © 2014 American Society of Civil Engineers.
