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.

An automatic music transcriber is a device that detects, without human interference, the musical gestures required to play a particular piece. Many techniques have been proposed to solve the problem of automatic music transcription. This paper presents an overview on the theme, discussing digital signal processing techniques, pattern classification techniques and heuristic assumptions derived from music knowledge that were used to build some of the main systems found in the literature. The paper is focused on the motivations behind each technique, aiming to serve both as an introduction to the theme and as resource for the development of new solutions for automatic transcription. © 2013 The Brazilian computer Society.

作者： Abhirup Chakraborty Ajit Singh School of Informatics and Computer Science Indiana University Bloomington Indiana Department of Electrical and Computer Engineering University of Waterloo ON Canada

The availability of a large number of processing nodes in a parallel and distributed computing environment enables sophisticated real time processing over high speed data streams, as required by many emerging applications. Sliding window stream joins are among the most important operators in a stream processing system. In this paper, we consider the issue of parallelizing a sliding window stream join operator over a shared nothing cluster. We propose a Bulk Synchronous Processing (BSP) framework, based on a fixed or predefined sequence of communication, to distribute the join processing loads over a shared-nothing cluster. We consider various processing and communication overheads while scaling over a large number of nodes, and propose solution methodologies to cope with the *** implement the algorithm over a cluster using a message passing system, and present the experimental results showing the effectiveness of the join processing algorithm.

Objective of this paper is to define an innovative control scheme to reduce congestion in freeway traffic systems via ramp metering. Such a control scheme is event-based and is composed of two control levels. At the lower level, Model Predictive Control is applied: the cell transmission model, reformulated in the so-called mixed-logical dynamical form, is adopted as internal model for the prediction and the quadratic deviations of the system variables from specific set-points are used as objective function in the finite horizon optimal control problem. The higher level of the control scheme consists of a discrete-event supervisor capable of distinguishing between regular and specific traffic conditions, adjusting the control law accordingly. More precisely, on the occurrence of classified events, the discrete-event supervisor determines the most suitable control action by making the controller switch among the elements of a set of model predictive controllers based on different internal models and cost functions.

Quantitative analysis of the dynamics of tiny cellular and subcellular structures in time-lapse cell microscopy sequences requires the development of a reliable multi-target tracking method capable of tracking numerous similar targets in the presence of high levels of noise, high target density, maneuvering motion patterns and intricate interactions. The linear Gaussian jump Markov system probability hypothesis density (LGJMS-PHD) filter is a recent Bayesian tracking filter that is well-suited for this task. However, the existing recursion equations for this filter do not consider a state-dependent transition probability matrix. As required in many biological applications, we propose a new closed-form recursion that incorporates this assumption and introduce a general framework for particle tracking using the proposed filter. We apply our scheme to multi-target tracking in total internal reflection fluorescence microscopy (TIRFM) sequences and evaluate the performance of our filter against the existing LGJMS-PHD and IMM-JPDA filters. © 2013 Springer-Verlag.

Enterprise governance basically is a framework, principles and policies, structures, processes and practices, information, skills, culture, ethics, and behavior to determine direction and monitoring related to compliance and performance that align with enterprise goals. COBIT 5 provides guidance that enterprise governance is influenced by individual and collective factors. The existence of this factor will influence process ini scope of governance enterprise either for governance and management area. University governance is a behavior, manner or method used by the college to utilize full potential and optimization elements, in order to achieve the vision and mission that has been set. Model of Vocational University Governance are built based on governance university components and principles of good university governance with reference models that exist within ISO 38500 framework. Enablers that exist within COBIT 5 framework will be used as a determining factor in the preparation of the proposed model of governance and measurement model of vocational university governance.

In this work, a novel framework for automated, spatially-adaptive adjustment of active contour regularization and data fidelity parameters is proposed and applied for medical image segmentation. The proposed framework is tailored upon the isomorphism observed between these parameters and the eigenvalues of diffusion tensors. Since such eigenvalues reflect the diffusivity of edge regions, we embed this information in regularization and data fidelity parameters by means of entropy-based, spatially-adaptive 'heatmaps'. The latter are able to repel an active contour from randomly directed edge regions and guide it towards structured ones. Experiments are conducted on endoscopic as well as mammographic images. The segmentation results demonstrate that the proposed framework bypasses iterations dedicated to false local minima associated with noise, artifacts and inhomogeneities, speeding up contour convergence, whereas it maintains a high segmentation quality.

In a classification problem typically we face two challenging issues, the diverse characteristic of negative documents and sometimes a lot of negative documents that are closed to positive documents. Therefore, it is hard for a single classifier to clearly classify incoming documents into classes. This paper proposes a novel gradual problem solving to create a two-stage classifier. The first stage identifies reliable negatives (negative documents with weak positive characteristics). It concentrates on minimizing the number of false negative documents (recall-oriented). We use Rocchio, an existing recall based classifier, for this stage. The second stage is a precision-oriented "fine tuning", concentrates on minimizing the number of false positive documents by applying pattern (a statistical phrase) mining techniques. In this stage a pattern-based scoring is followed by threshold setting (thresholding). Experiment shows that our statistical phrase based two-stage classifier is promising. © 2013 Springer-Verlag.

Word recognition testing may be defined as a procedure to assess a listener’s ability to identify one-syllable words (such as phonetically-balanced/PB words) that are presented at a given suprathreshold level to arrive at a word recognition score. For Thai, Thammasat University and Ramathibodi Hospital Phonetically Balanced Word Lists 2015 (TU-RAMA PB’15) were created with five lists, each with 25 monosyllabic words. Besides its phoneme distributions being based on large-scale Thai spoken corpora, TU-RAMA PB’15 is in line with TU PB’14 with emphasis on phonetic balance, symmetrical phoneme occurrence, and word familiarity. To evaluate its homogeneity in terms of decibel intelligibility, the lists were recorded and presented to 10 normal hearing participants, ranging from 0 to 50 dB HL in 2 dB increments (ascending order) until they repeated correct verbal responses. Using logistic regression, regression slopes and intercepts were calculated to estimate percentage of correct performance at any given intensity and to construct psychometric functions for every list. Derived psychometric function slopes ranged from 0.2015 to 0.2262 while intensities required for 50% intelligibility ranged from 17.0876 to 20.8856. Two-way Chi-Square analysis performed on both parameters indicated that there was no significant difference among the five lists.
