Design and optimization of optical grids and clouds

Grids use a form of distributed computing to tackle complex computational and data processing problems scientists are presented with today. When designing an (optical) network supporting grids, it is essential that it can overcome single network failures, for which several protection schemes have been devised in the past. In this work, we extend the existing shared path protection scheme by incorporating the anycast principle typical of grids: a user typically does not care on what specific server this job gets executed and is merely interested in its timely delivery of results. Therefore, in contrast with classical shared path protection (CSP), we will not necessarily provide a backup path between the source and the original destination. Instead, we allow to relocate the job to another server location if we can thus provide a backup path which comprises less wavelengths than the one CSP would suggest. We assess the bandwidth savings enabled by relocation in
Measuring and Analysing the Variations of Program Execution Times on Multicore Platforms: Case Study

The recent growth in the number of precessing units in today's multicore processor architectures enables multiple threads to execute simultanesiouly achieving better performances by exploiting thread level parallelism. With the architectural complexity of these new state of the art designs, comes a need to better understand the interactions between the operating system layers, the applications and the underlying hardware platforms. The ability to characterise and to quantify those interactions can be useful in the processes of performance evaluation and analysis, compiler optimisations and operating system job scheduling allowing to achieve better performance stability, reproducibility and predictability. We consider in our study performances instability as variations in program execution times. While these variations are statistically insignificant for large sequential applications, we observe that parallel native OpenMP programs have less performance stability. Understanding the performance instability in current multicore architectures is even more complicated by the variety of factors and sources influencing the applications performances.
PENGEMBANGAN ROUTING PROTOCOL UNTUK GATEWAY AD HOC WIRELESS NETWORKS

Jaringan ad hoc adalah kumpulan dari beberapa mobile host yang membentuk suatu jaringan yang bersifat sementara tanpa ada infastruktur dan administrasi terpusat dengan karakteristik topologi yang dinamis. Hal ini menimbulkan masalah dalam hal routing dimana konvensional routing tidak didesain untuk topologi yang dinamis.Protokol rute harus dapat meminimalkan kontrol trafik misalnya periodik update message. Selain itu protokol rute harus reaktif, dimana hanya akan mencari atau menentukan suatu rute ketika menerima request khusus. Penelitian-penelitian sebelumnya lebih menekankan pada single user dan satu base station, sedangkan dalam penilitian ini dikembangkan hubungan antara gateway dengan beberapa terminal multi user. Karena masalah yang sering ditemui dalam komunikasi wireless adalah bagaimana menemukan rute yang cocok untuk mengirimkan paket data ke tujuan yang diinginkan, maka pembangunan protokol rute pada terminal yang difungsikan sebagai ad hoc untuk multi user mengacu pada suatu algoritma routing protocol, yang dipakai untuk memodelkan routing untuk gateway. Hasil yang diperoleh ini dipakai sebagai pengembangan platform untuk sistem komunikasi yang lebih luas.
Using a fully open source approach to working with OpenStreetMap

OpenStreetMap is a very exciting and vibrant project aiming to make accessing geographic data easier. Our research group at the Department of Computer Science NUI Maynooth Ireland is carrying out research into a broad range of topics including: map data generalisation, geographic shape complexity, web map services, map-based interface for pedestrian navigation. One of the common themes across this research is the use of OpenStreetMap as the principal source of geospatial data. In this paper we describe how our research productivity, research collaboration, and general data interoperability have been greatly enhanced from our early adoption of a fully open source GIS approach to working with OpenStreetMap. While one can work successfully with OpenStreetMap in non-Open Source environments the flexibility offered by an open source approach is a major advantage. This flexibility is delivered in many flavours including: a wide choice of software, inter-connectability of software packages and components, a wide network of support through documentation, message boards, and free and open exchange of ideas.
Evaluation of Performance for Optimized Routing in MPLS Network

Emerging demand for the sophisticated services such as videoconferencing, Voice over Internet Protocol (VOIP) has led to tremendous need for high link capacity, low packet drop and delay. Multi Protocol Label Switching (MPLS) is going to provide next generation Quality of Service (QoS) and traffic engineering (TE) architecture for the Internet. In this work a routing algorithm for different MPLS topologies which can reduce the congestion by avoiding the critical path and reserving path for future request is proposed and designed. The packets are explicitly routed and we compare the results with IPv4 configurator for the performance evaluation using OMNET++ simulator. Keywords—MPLS,Optimization,Routing,Omnet++,Traffic Engineering,QoS,Explicit, IPv4.
An Extended Content-based Procedure to Solve a New Item Problem

Nowadays various new items are available, but limitation of searching effort makes it difficult for customers to search new items which they want to purchase. Therefore new item providers and customers need recommendation systems which recommend right items for right customers. In this research, we focus on the new item recommendation issue, and suggest preference boundary- based procedures which extend traditional content-based algorithm. We introduce the concept of preference boundary in a feature space to recommend new items. To find the preference boundary of a target customer, we suggest heuristic algorithms to find the centroid and the radius of preference boundary. To evaluate the performance of suggested procedures, we have conducted several experiments using real mobile transaction data and analyzed their results. Some discussions about our experimental results are also given with a further research area.
Efficient methods for high quality low bit rate wideband speech coding

This paper describes efficient encoding and decoding methods for achieving high quality wideband speech at low rates. CELP-based technologies have been successful in achieving high quality speech at low bit rates, however, new efficient techniques are needed to maintain high speech quality when the model is applied to wideband signals. This article discusses some techniques that improve the performance of the CELP model including efficient perceptual weighting and pitch codebook, and decoding techniques such as gain smoothing, periodicity enhancement, and high frequency generation. These techniques have been incorporated in the AMR-WB (adaptive multi-rate wideband) codec selected by 3GPP and ITU-T, where high quality wideband speech can be maintained at bit rates around 13 kbit/s.
Distributing video content using a router-assisted multicast mechanism

At this time, high quality on-demand video streaming services are expected to be one of the most promising applications of content distribution networks because of the wide-area deployment of broadband network and the advanced improvement of the video compression technologies. This paper proposes a simple mechanism called active video delivery (AVD) that provides an efficient group communication service for on-demand video systems. We describe how to construct an AVD tree where a multicast-like delivery service is effectively achieved. In our simulation results, we demonstrated our proposed AVD mechanism allows for significant reductions both in the average and maximum link load (link stress). In addition, we have evaluated the AVD performance according to varied percentages of routers that are ARs deployed in the simulation network.
Sobregeneración durante el análisis gramatical (overparsing), derivabilidad parcial, adyacencia y propagación de restricciones: el algoritmo SCP

La sobregeneracion durante el analisis gramatical (overparsing) es un problema que afecta a la mayoria de los algoritmos de parsing para gramaticas libres de contexto. Este trabajo introduce esta nocion y estudia su influencia en los algoritmos de Earley, Kay (chart) y Tomita (GLR). El segundo objetivo consiste en analizar el comportamiento del algoritmo SCP ante este problema. Basicamente, el algoritmo SCP elimina la sobregeneracion gramatical mediante la aplicacion de la tecnica de propagacion de restricciones sobre un modelo formal basado en las relaciones de derivabilidad parcial y adyacencia.
Designing a structured lexicon for document image analysis

This paper presents a structured, multi-level architecture of a lexicon which is a central component of our knowledge-based document analysis system. Our system has the task to transform incoming business letters into an equivalent electronic representation automatically. Moreover, partial text analysis and understanding of a letter's body and relevant parts are initiated to enrich the conceptual knowledge about the actual document (e.g., by a classification). In such an application domain, a well-designed lexicon has to consider requirements of both, text recognition and text analysis. For that purpose, we propose an appropriate lexicon architecture and the internal structure of corresponding lexical entries being a prerequisite for successful higher-level interpretations of documents.
A software architecture for behavioral control strategies of autonomous systems

The authors deal with the execution of several tasks for mobile robots while exhibiting various primitive behaviors in a simultaneous or concurrent fashion. The architecture allows for learning to take place, and at the execution level it incorporates the experience gained in executing primitive behaviors as well as the overall task. Some empirical rules are provided for the appropriate mixture of primitive behaviors to produce tasks. The architecture has been implemented in OPMOR, a simulation environment for mobile robots, and several results are presented. The performance of the architecture is excellent. <<ETX>>
Continuous classification of myoelectric signals for powered prostheses using gaussian mixture models

Pattern recognition is a key element of myoelectrically controlled prostheses. Improvements in classification accuracy have been achieved using various feature extraction and classification methodologies. In this paper, it is demonstrated that using a simple and direct approach can achieve high classification accuracy, while maintaining a low computational load; important characteristics for a real-time embedded system. An average classification accuracy of 94.06% was achieved for a six class problem, using a single mixture Gaussian mixture model, along with majority vote post-processing.
Learning and Network Collaboration in Product Development: How Things Work for Human Use

This article studies the learning and capability formation of a biotechnology firm by analysing its development path, which is composed of successive product development and innovation processes. In collaborative product development work, network collaboration, as well as the acquisition of new competences and learning, evolves simultaneously and interactively. Searching for and encountering partners with complementary knowledge and resources is important in the emergence of new product-development processes. To improve understanding of this path formation, the article draws on cultural—historical activity theory, science and technology studies and the epistemology of things and effects. These all underline the significance of material artefacts for learning and activity. The epistemology of things and effects addresses the knowledge of how things work in experimental systems and products. Enzymes, proteins and instruments are put to work in a stabilized way as parts of new products. The effects so mastered entail the functional qualities that make products competitive in the marketplace.
Projector-based three dimensional graphics

Ramesh Raskar Projector-based Three Dimensional Graphics (Under the direction of Henry Fuchs and Gregory Welch) Light projectors can be arranged into electronic displays that offer large, bright, and high resolution images. However, despite their unique characteristics, projectors have been treated like any other two-dimensional display devices, e.g. CRT monitors or LCD panels, to create flat and usually rectangular images. Even the growth of three dimensional computer graphics has followed this limitation. To improve and widen the range of applications of projectors, in this dissertation I present a single unified geometric framework for projector-based graphics. It is based on the notion of the projector as the dual of a camera. The geometric framework is based on (i) the analytical projection model, (ii) the geometric representation of the display surface and (iii) the viewer location. The framework can be used for practically all the projector-based applications. For classic projectorbased systems, such as tiled displays or immersive panoramic displays, the framework provides a fundamentally different approach that allows greater freedom and flexibility. In addition, it enables a new class of projector-based visualization methods.
2. Online learning and the evaluation of group processes

The current rapid increase in online classes using learning community approaches and the emergence of learning communities in knowledge economy businesses has created an awareness that little is known about the group dynamics that allow learning communities to succeed or fail. In recent years, an innovative network science approach to the understanding of group processes has evolved. This approach allows the discovery of patterns among group interactions. The Knowledge Forum knowledge building environment has a suite of online tools for tracking students’ interactions with the environment, and these interactions are analyzed using network analysis techniques. In a study of a Gr. 5/6 hybrid class, it was found that a network analysis of note reading showed a very high note reading density of 92%, that building-on was much lower at 15%, and that note contribution rates showed a linear trend. Sociograms are used as a network visualization tool, including both 2-D and 3-D network visualizations. Interpreting these data in light of the instructor’s knowledge of the class can yield useful data about student performance within the group.
Big systems and sensibility of space perception

We made a psychological review on the communication between a man and an artificial big system, and emphasized the necessity of farther interdisciplinary approach to the sensibility processing of both human and artificial system. As the old two factors theory of intelligence pointed out, the sensibility is originally an elemental function for biological adaptation to the environment. It has different aspects for every sensory modality, and the large variance of the individual difference is essential characteristic. Perception of objects and psychological space was discussed as a most early and primitive sensibility. Under the notion that the perception is a problem solving process, we reviewed models of visual perception and proposed a canvas model, which assume information integration by unconscious attention. 3-dimensional space perception was discussed as a result of information reduction by visual system. Biological motion perception proved a hierarchical structure just as knowledge system. Inner dialog mechanism between two arrays of composing units would be essential for the adaptive information processing of the big system. <<ETX>>

Development and implementation of adaptive echo cancellation techniques

In telecommunications, the echo canceler using an adaptive filter is the most effective technique for controlling echoes. This paper presents the structure of an echo canceler based on two different echo path models. The speech detectors use a three-variable-length window technique as the far-end speech detector. Double-talk detectors based on the echo return loss enhancement (ERLE) are also developed and evaluated. The overall systems have been implemented on the TMS320C54x.
