Time synchronization is the basic to cooperation. Many protocols are developed. However, they are either rather complicated or relying on infrastructure such as GPS. In this paper, a physical layer approach is proposed. Without complex protocols and not reliable to other systems, this approach has a better efficiency. The synchronization method is proposed and the corresponding platform is demonstrated. The analysis on how the error of synchronization deteriorates the performance is given and the solutions are shown thereafter.","PeriodicalId":328695,"journal":{"name":"2015 IEEE 14th International Conference on Cognitive Informatics & Cognitive Computing (ICCI*CC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129223544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering that multiple users are available in cellular network, we present three multi-user scheduling schemes, namely the round-robin scheduling scheme, the suboptimal and optimal user scheduling schemes to improve the security of communication (from users to BS) against the eavesdropping attack. In the suboptimal scheduling, we only need to assume that the channel state information (CSI) of the main link spanning from users to BS are known. In contrast to the suboptimal scheduling, the optimal scheduling is designed by assuming the CSI of the main link and wiretap link (spanning from users to the eavesdropper) that are available. We obtain the calculus form of the secrecy outage probability to analyze the secrecy diversity performance. Secrecy diversity analysis is carried out, which shows that the round-robin always achieves only one diversity order, whereas the suboptimal and optimal user scheduling schemes achieve the full diversity order. In addition, the results of the secrecy outage show that the optimal scheduling has the best performance and the round-robin performs the worst in terms of defending against the eavesdropping attack. Lastly, as the number of users increases, both the secrecy outage probabilities of the suboptimal and optimal scheduling schemes have a significant secrecy performance improvement.","PeriodicalId":328695,"journal":{"name":"2015 IEEE 14th International Conference on Cognitive Informatics & Cognitive Computing (ICCI*CC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129367937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the limited spectrum, video coding has to be developed for efficient video delivery. The core of video coding is compressing video frames by exploiting their redundancy. Aiming at decreasing spatio-temporal redundancy, several video coding standards have been proposed with a hybrid framework during the past two decades. We therefore first survey in this paper the existing standards on video coding. Second, we review some other video coding approaches, which take advantage of state-of-the-art computer vision and machine learning technologies, for lessening both spatio-temporal and perceptual redundancy of images/videos. In retrospect of what has been achieved so far, we finally outlook what the future may hold for video coding.","PeriodicalId":328695,"journal":{"name":"2015 IEEE 14th International Conference on Cognitive Informatics & Cognitive Computing (ICCI*CC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125471695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our KIVC system, we choose Kinect as the camera for capturing the videos, benefiting from the state-of-the-art computer vision toolbox integrated in Kinect. In addition, in order to improve QoE with the constraint on the limited bandwidth, we develop a framework for KIVC system. Then, in our KIVC system, several advanced key technologies are adopted, e.g., fast object-based video coding for real-time data, human-computer interaction, and blurring processing for attracting human visual attention. Extensive experimental results show that our KIVC system has excellent performance and achieves a reliable real-time processing results.

In the classification of 11 POF species, POC achieved 97.64% of 10-fold cross validation accuracy. Besides, we also propose a new POF dataset consisting of 100 samples for each species and illustrated the prediction performance of several renowned classifiers such as Naïve Bayes, K-nearest and Decision Tree.

Conflict avoidance is one way to manage conflicts. Intuitively, we may try the best to avoid conflicts when initiating a collaborative activity, because we may save the effort of conflict resolution. However, conflict avoidance is a complex task that requires many efforts. We need to know if we could get a reward from our payment in conflict avoidance. This paper sets up a model to evaluate the collaboration performance before and after conflict avoidance; conducts experiments with simulations; finally conclude the benefits for conflict avoidance. The contribution of this paper is to assert that conflict avoidance is beneficial in most cases unless the conflicts are not severe, there are not many conflicts, and the number of roles is too small.","PeriodicalId":328695,"journal":{"name":"2015 IEEE 14th International Conference on Cognitive Informatics & Cognitive Computing (ICCI*CC)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124589611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Probabilistic programming allows artificial systems to better operate with uncertainty, and stochastic arithmetic provides a way to carry out approximate computations with few resources. As such, both are plausible models for natural cognition. Our work on the automatic design of probabilistic machines computing soft inferences with an arithmetic based on stochastic bitstreams allowed us to develop the following compilation toolchain: given a high level description of some general problem (typically to infer some knowledge from a model given some observations), formalized as a Bayesian Program, our toolchain automatically builds a low level description of an electronic circuit computing the corresponding probabilistic inference. This circuit can then be implemented and tested on reconfigurable logic.We designed as a validating example a circuit description of a Bayesian filter solving the problem of Pseudo Noise sequence acquisition in telecommunications.","PeriodicalId":328695,"journal":{"name":"2015 IEEE 14th International Conference on Cognitive Informatics & Cognitive Computing (ICCI*CC)","volume":"7 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124909244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using traditional keyword search metrics may acquire a wrong result that these two web services are similar. But semantics of the web services is hardly to exploit. In this work we use association rule to find terms that are often appear together and find the most similar terms.
