While heart disease is one of the three major diseases, only well-qualified doctors can evaluate phonocardiographic signals. This calls for an easily available system that can automatically diagnose phonocardiographic signals. When recording in a room, suppression is required as these signals are heavily contaminated by noise from various sources such as air conditioners and fans. Wavelet transform is one method for denoising phonocardiographic signals, but appropriate parameters are required. In this study, we investigated both normal and abnormal phonocardiographic signals to determine the appropriate use of single and multilevel thresholds and the best types of wavelet functions. The experiment results show that the most appropriate wavelet function is Symlet14 and multilevel thresholding is best for low SNRs.

There is a strong relationship between scientific research and technology advancement. The former generally focuses on studying phenomena happening in the real world, the latter improves tools that are at the basis of this research. From this perspective, information and communication technologies allow the implementation of ever faster tools for analyzing data generated by experiments. The aim of DemoGRAPE project is to study the interaction of the upper earth atmosphere and the GNSS (Global Navigation Satellite Systems) signals received at ground, in critical environments such as the polar regions. This paper describes the ICT infrastructure used to manage the software applications used to analyzed data collected during project experimental campaigns, taking into account the following constraints: (i) the intellectual property of the applications must be protected, (ii) the underlying infrastructure resembles a cloud-federation, (iii) data are over-sized, (iv) provide a unified vision of the available resources to the user (i.e., what are the available applications, and where experimental data reside). Leveraging on a lightweight virtualization system, we proposed a management system that copes with all these four constraints. A case study is used to show the process of deploying an application through the proposed system on a specific node where data of interest reside.

A large number of isomorphic polygons are included in design data of large scale integrated circuit. Fast search and classification for isomorphic polygons in these design data are expected to apply to compactification of design data and fast pattern search. A pattern matching method was proposed to reduce a large amounts of design data efficiently. In this method, feature of polygon shape is expressed by an angle-segment sequence called contour signature. So, this method realizes fast processing by efficient comparison using the contour signature. Furthermore, this method realizes compactification of the design data by hashing of classification results. However, there is a problem that feature amounts increase with increase of the number of vertices of polygons. As a result, computation amounts and memory usage amounts are increased. To solve this problem, in this paper, we propose a high speed and high accuracy classification method of isomorphic polygons. The proposed method can reduce a shape comparison process significantly by using a geometric invariant feature value for a polygon. The feature value is calculated by summation of distance from each vertex to center of gravity, and a polygon contour length. This value does not be affected by parallel shift, rotation and reduced scale. The feature value is same for isomorphic polygons and it is possible to fast access an isomorphic polygon group. From evaluation results of the proposed method, we verified that the proposed method can realize fast classification for isomorphic polygons, and compactification of design data.

In previous work it has been shown that volume registration can be used to generate dense 3D maps from RGBD video data with various advantages over feature matching approaches. This paper presents preliminary work in applying this technique to general monocular video data. This approach does not require additional RGB-D hardware and generates dense 3D models with similar complexity.

A distributed system is considered in an event-driven model composed of processes which are sequences of events. In this paper, we discuss a peer-to-peer (P2P) model of a topic-based publish/subscribe system (P2PPS model) where each peer process (peer) can both subscribe interesting topics and publish event messages. Since each peer can both publish and receive event messages, a peer may publish an event message e1 after receiving an event message e2. In the P2PPS system, event messages have to be notified to every common target peer in the causal order. In the TBC (topicbased causally delivery) protocol, event messages are causally delivered by taking advantage of physical time in addition to linear time and topic vector. Physical time is used to reduce pairs of event messages unnecessarily ordered. In this paper, we discuss the relation among the clock offset and delay time in the evaluation.

Molecular biomarkers are important and commonly used as classification features for detecting function performances of target genes and distinguishing characteristics of different species or strains. As expeditious development in Next Generation Sequencing technologies, whole genome sequencing delivers a comprehensive view and new insights for novel species. However, utilization of whole genome sequences to discover genetic biomarkers for specific functional gene groups still possess many challenges. To solve this problem, we utilized Gene Ontology definitions and Ensembl orthologous information to decide a set of associated functional genes according to user's query keywords. Then, previously assembled NGS contigs were matched against the selected gene set from model species, and an SSR searching algorithm and a cross-species comparison mechanism were performed to reveal potential polymorphic SSR biomarkers. Each identified SSR would be annotated and classified by important attributes, such as lengths, genetic locations, fundamental repeat patterns, tolerant rates of retrieved SSRs. The developed system could identify novel SSR biomarkers for a specified functional gene group regarding conserved and unique features between the query and the target model species, and which could facilitate biologists in finding potential markers for elucidating biological functions and distinguishable features of a novel species.

Several schemes have been proposed for handover in wireless cellular networks. However, during the complexity of handover in wireless environment, many simplified models and assumptions are made. Also, the handover algorithms operating in real time have to make decisions without the luxury of repeated uncorrelated measurements or the future signal strength information. It should be noted that some of handover criteria information can be inherently imprecise, or the precise information is difficult to obtain. For this reason, we propose a Fuzzy Logic (FL) based approach for handover for wireless cellular networks (Secure-aware Fuzzy-based Handover System: S-FBHS) considering the security parameter for the FBHS. The simulation results show that the S-FBHS has a good behavior.

Based on core point evolution using water ripplemodel, the thought of software development methodology is thatthe development of a complex system is translated into the waterripple sustainable evolution of core point. However, the corepoint is defined from three levels, which are domain, feature andfunction. And it does not give a general definition of the corepoint. In addition, the evolution of the core point only gives asimple evolutionary model, and there is no evolutionary algorithmbetween the core points. To address these problems, this paperfurther improves the feature and function core points, and putforward the framework and level core points. Then, this paperalso give the corresponding evolutionary algorithm. Based onthese two points, this paper developed a prototype system inorder to demonstrate the water ripple evolution of the varioustypes of core points.
