Complex Event Processing (CEP) is a set of tools and techniques that can be used to obtain insights from high-volume, high-velocity continuous streams of events. CEP-based systems have been adopted in many situations that require prompt establishment of system diagnostics and execution of reaction plans, such as in monitoring of complex systems. This article describes the Query Analyzer and Manager (QAM) module, a first effort toward the development of a CEP as a Service (CEPaaS) system. This module is responsible for analyzing user-defined CEP queries and for managing their execution in distributed cloud-based environments. Using a language-agnostic internal query representation, QAM has a modular design that enables its adoption by virtually any CEP system.

Although still considered experimental by some, computerized posturography is becoming more and more the standard assessment of balance and neuromuscular control mechanisms while standing. However, there is no consensus as to the data acquisition parameters to be used. Depending on which posturography school one belongs to, acquisition frequencies vary from a few Hz all the way to 1 kHz, and little attention is usually given to the post-sampling filter cut-off frequency (implemented either in the hardware or in the software used to acquire the data), often without realizing the consequences such choices will have on the results. But the sampling and the filter cut-off frequencies are particularly important when dealing with spectral analysis or when secondary measurements such as the center of pressure coordinates, sway path length, velocity or acceleration are calculated from the measured forces and moments. In this paper, frequency content of vertical ground reaction force and center of pressure path coordinates excursion were determined for 946 subjects of both genders, with various age, height, body type, health status and nationality. The results of this spectral analysis made it possible to draw some general conclusions as to what should be a proper acquisition frequency for posturographic data. © 2013.

The present paper focuses on maintaining one’s data secrecy in cloud storage area and it may depend on their privacy policy and standards. The effectiveness and efficiency of preserved data from different cloud providers should maintain the integrity of original data stored in it. In the era of could computing, stored information’s value, proficiency and optimization of data retrieving spotlights the importance of maintaining cloud users data, privacy, identity, reliability and maintainability it may vary for different Cloud providers (CP). Giant CP ensures their user proprietary information’s are sustained more secretly using cloud technologies. During third party cloud services and exodus between inter cloud providers may lead to data portability privacy issue. More remarkable event in this case, even the cloud providers don’t have implication about the information and records where it’s stored and maintained in their own cloud. This is one of the obligatory research issue in cloud computing. We came frontward by proposing (EMPPC) an Evolutionary model based privacy Preserving technique and try to hold user’s, to have trust in providers for maintaining their confidentiality in cloud. This proposal helps the CR (Cloud Requester and Users) to mark trust on their proprietary information and data’s stored in cloud. © inst.tute for computer Sciences, Social informatics and Telecommunications engineering 2013.

Due to the sudden eruption of activity in the social networking domain, analysts, social media as well as general public are drawn to Sentiment Analysis domain to gain invaluable information. In this paper, we go beyond basic sentiment classification (positive, negative and neutral) and target deeper emotion classification of Twitter data. We have focused on emotion identification into Ekman's six basic emotions i.e. JOY, SURPRISE, ANGER, DISGUST, FEAR and SADNESS. We have employed two diverse machine learning algorithms with three varied datasets and analyzed their outcomes. We show how equal distribution of emotions in training tweets results in better learning accuracies and hence better performance in the classification task.

We propose the direct production of 3D CSG models from sketches as a way of relieving the user from having to input detailed 3D CAD models. This shortens the CAD/CAM process and simplifies it, allowing non-expert end-users to produce their own designs. Early detection of features in the 2D sketch is a critical step. This paper discusses a general strategy for solving this problem, and then describes our approach for detecting steps and pockets in a 2D line-drawing obtained after vectorising the sketch captured by an input device.

Broadband is an important tool for increasing productivity and competitiveness. This paper attempts to measure the accumulative impact and effectiveness of broadband public infrastructures and services on the economy of South East Europe (SEE) areas. To this direction, we focus on evaluating the correlation between broadband and each country's growth and employment. Moreover, we estimate the cost savings achieved by the extended usage of e-services, and we evaluate the potential cost savings that will follow the increase of e-services utilization the next years. The results of our analysis show that broadband may have positive impact on growth and employment and that the possible savings are substantial.

This paper concerns multimodal transport systems (MTS) represented by a supernetworks in which several unimodal networks are connected by transfer links and focuses on the scheduling problems encountered in these systems. Assuming unimodal networks are modeled as cyclic lines, i.e. the routes determining stream-like moving transportation means, a problem of an alternative itinerary selection for an origin-destination (O-D) trip in the context of emergency relief is considered. Emergency relief dealing with the contingency events and deciding on MTS robustness can be evaluated in terms of feasible itineraries for assumed (O-D) trip. Since itinerary planning problem, constitutes a common routing and scheduling decision faced by travelers, hence the main question regards of itinerary replanning and particularly a method aimed at prototyping of mode sequences and paths selections. The declarative model of multimodal processes driven itinerary planning problem is our main contribution. Illustrative examples providing alternative itineraries in some cases of MTS malfunction are presented. © IFAC.

2013 4th International Conference on Information technology for Manufacturing Systems(ITMS 2013)

作者： Bocewicz Grzegorz Muszyński Wojciech Banaszak Zbigniew Dept. of Electronics and Computer Science Koszalin University of Technology Institute of Computer Engineering Control and Robotics Wroclaw University of Technology Dept. of Business informatics Warsaw University of Technology

The paper presents constraint satisfaction problem driven approach to analytical solution of the cyclic scheduling problem in the Flexible Manufacturing System(FMS) producing multi-type parts where for material handling are used the Automated Guide Vehicles Systems(AGVS). Finding the conditions guaranteeing the AGVs deadlock-free and collision-free movement policy is the aim of our researches. The AGVs co-sharing the common parts of the transportation route while executing repetitive processes, i.e. being assigned to AGVs passing along machines in a cyclic way, can be modeled in terms of Cyclic Concurrent Process Systems(CCPS). Schedulability analysis for a given CCPS answers the question whether a cyclic schedule exists or not. The paper suggests approach for schedulability analysis of multimodal processes representing real manufacturing employing the declarative modeling.

Many countries, European and worldwide, have increasingly issued during the last decade electronically readable identity documents to their citizens, for different purposes and applications. However, a major characteristic of all these systems is that they are basically available in a national context. For example, European citizens that move freely through the Member-States face the problem that their eIDs from their home state do not allow access to services of another Member-State in which they are temporarily present. Public Administrations are also unable to provide services to European citizens from other Member-States with the same ease and efficiency as they do to their national citizens. In order to avoid such confusing situations, cross-border services should be fully integrated in the national/regional and local information systems. It is, therefore, an important task to improve the cross-border interoperability of electronic identification and authentication systems. ENISA, the European agency for the security of computer systems and networks, recently published a report dealing with an important aspect of this problem: the security issues in cross-border electronic authentication. The report assesses the risks of electronic authentication in cross-border solutions and provides a generic implementation model. This paper describes an implementation methodology for addressing the cross-border interoperability of electronic authentication problem, based on the ENISA generic model. The proposed implementation methodology has been based on the successful NETC@RDS project approach and experience, described herein. This methodology can provide a suitable secure cross-border, multi-purpose authentication implementation based on the aforementioned generic model that can be used in various sectors. © IFIP International Federation for Information Processing 2013.
