During gene expression, transcription factors are unable to bind to a transcription binding site (TFBS) involved in regulation if DNA methylation has occurred at the TFBS. Methyl-CpG-binding proteins may also occupy the TFBS and prevent the functioning of a transcription factor. Thus, the methylation status of CpG sites is an important issue when trying to understand gene regulation and shows strong correlation with the TFBS involved. In addition, CpG islands would seem to undergo cell-specific and tissue-specific methylation. Such differential methylation is presented at numerous genetic loci that are essential for development. Current DNA methylation site prediction tools need to be improved so that they include TFBS features and have greater accuracy in terms of the DNA region that is involved in methylation. We developed models that compare the differences across these regions and tissues. The TFBSs, DNA properties and DNA distribution were used as features for this classification. From the results, we found some TFBSs that were able to discriminate whether a sequence was methylated or not. The sensitivity, specificity and accuracy estimated using 10-fold cross validation were 90.8%, 80.54%, and 86.07%, respectively. Thus, for these four regions and twelve tissues, the performance levels (ACC) were all greater than 80%. We propose that the differential features or methylations vary between the different regions because the features common to each DNA region made up only 50% of the top 70 features. An online predictor based on EpiMeP is available at http://140.115.51.41/EpiMeP/. Supplementary file is available at http://140.115.51.41/EpiMeP/***.

ACM/IEEE International Conference on Distributed Smart Cameras, ICDSC

作者： Michael Wittke Martin Hoffmann Jorg Hahner Christian Muller-Schloer Institute of Systems Engineering System and Computer Architecture Leibniz Universität Hannover Hanover Germany

Each mobile phone with a built-in CMOS sensor can inherently be seen as smart camera itself. Previous work in the research field of smart camera networks intensively focused on custom hardware solutions to optimise the execution of computationally intensive computer vision algorithms. In contrast, we propose an architecture for smart camera networks consisting of low-cost mobile Internet devices (e.g. mobile phones or PDAs). Due to mass production their price decreases steadily, although their processing capacity as well as their networking abilities increases. New standards like LTE promise bandwidth increases as high as 100 Mbps on the downlink, and up to 50 Mbps on the uplink. In this paper, we present MIDSCA, an architecture for self-organising smart camera networks consisting of mobile Internet devices. One component of our architecture uses visual events themselves to implement an algorithm which is able to synchronise mobile devices with the same field of view with the accuracy of one frame. This synchronisation makes way for future mobile surveillance scenarios as multiple cameras are able to establish a common notion of concurrent events. An initial prototype of MIDSCA has been developed and bases upon a Linux operating system. Evaluations show that our algorithm is highly suitable for mobile devices as it is mostly invariant with respect to distinct perspectives and illuminations.

DMCtrac: Distributed multi camera tracking

DMCtrac: Distributed multi camera tracking

ACM/IEEE International Conference on Distributed Smart Cameras, ICDSC

作者： Martin Hoffmann Michael Wittke Yvonne Bernard Ramin Soleymani Jorg Hahner Institute of Systems Engineering System and Computer Architecture Leibniz Universität Hannover Hanover Germany

Advances in the field of computer vision enable smart cameras to cooperatively analyse scenes without human intervention. Large networks of autonomous, self-organising PTZ (pan, tilt, zoom) cameras require algorithms and protocols that make way for cooperation between multiple smart cameras (SCs). This paper introduces a distributed algorithm for object tracking with multiple SCs (DMCtrac). The focus lies on PTZ management issues arising in large SC systems rather than on computer vision algorithms. DMCtrac enables SCs to observe objects throughout an area under surveillance by using their PTZ abilities to follow these objects. The algorithm has been evaluated by simulation of SC systems with up to 50 SCs as used for example for people tracking and traffic analysis. Results show, that DMCtrac is able to cope with large numbers of SCs and objects and is robust towards real world disturbances like communication failure.

This paper presents a new methodology for assessing both reliability and well-being indices for composite generation and transmission systems. Firstly, a transmission network reduction is applied to find an equivalent for assessing composite reliability for practical large power systems. After that, in order to classify the operating states, Artificial Neural Networks (ANNs) based on Group Method Data Handling (GMDH) techniques are used to capture the patterns of the operating states, during the beginning of the non-sequential Monte Carlo simulation (MCS). The idea is to provide the simulation process with an intelligent memory, based only on polynomial parameters, to speed up the evaluation of the operating states. For the conventional reliability assessment, the ANNs are used to classify the operating states into success and failure. However, for the well-being analysis, only success states are classified into healthy and marginal by the ANNs. The proposed methodology is applied to the IEEE Reliability Test system 1996 and to a configuration of the Brazilian South-Southeastern system.

In this paper, a class of hybrid impulsive systems with time delays and stochastic effects are considered. We obtain some criteria on the global exponential stability in mean square for the impulsive stochastic delayed systems. To do this, differential inequalities and ℒ-operator inequalities are developed. An example is given to illustrate the effectiveness of our results.

Workshop on Workflows in Support of Large-Scale Science, WORKS

作者： Ivona Brandic Dejan Music Schahram Dustdar Srikumar Venugopal Rajkumar Buyya Institute of Information Systems University of Technology Vienna Austria Grid Computing and Distributed System (GRIDS) Laboratory Department of Computer Science and Software Engineering University of Melbourne Australia

In novel market-oriented resource sharing models, resource consumers pay for the resource usage and expect that non-functional requirements for the application execution, termed as quality of service (QoS), are satisfied. QoS is negotiated between two parties following the specific negotiation protocols and is recorded using service level agreements (SLAs). However, most of the existing work assumes that the communication partners know about the SLA negotiation protocols and about the SLA templates before entering the negotiation. However, this is a contradictory assumption, if we consider computational grids and novel, commercially oriented computing clouds where consumers and providers meet each other dynamically. In this paper, we present novel meta-negotiation and SLA-mapping solutions for grid workflows bridging the gap between current QoS models and grid workflows, one of the most successful grid programming paradigms. We illustrate the open research issues with a real world case study. Thereafter, we present document models for the specification of meta-negotiations and SLA-mappings. We discuss the architecture for the management of meta-negotiations and SLA-mappings as well as integration of the architecture into a grid workflow management framework.

Fractional Order Linear Quadratic Regulator

Fractional Order Linear Quadratic Regulator

In this paper, we formulate the fractional linear quadratic regulator (LQR) problem. The analytical solution of fractional optimal control near the origin and infinity are derived. It is shown that the optimal control to the linear fractional system can be computed through the corresponding fractional Euler-Lagrange equations. Moreover, the analytical analysis of right-sided fractional equation is discussed, which relates to the construction and solution of fractional LQR problems. The matrix Mittag-Leffler function is used here to serve as the fundamental solution of high-dimension linear fractional equations. More detailed discussions about fractional systems and right-sided fractional operators are provided and summarized. Finally, two illustrated simulation results are provided as a proof of concept.
