Central Management and Tree Based Auto-configuration in MANET
Authors: Zhang Ning, Sanmin Lee, Kiho Nam, Jongwan Kim, Jaepil Yoo, Kee-Cheon Kim
Venue: Proceedings of the 2009 International Conference on Advanced Computer Control (2009)

Nowadays, IPv6 address system has been proposed since nearly ten years ago, the most attractive trait of this address system is the address auto-configuration. But all of these technologies are based on the wired network. In wireless network, especially in the ad hoc network, because of its dynamic and self-organized trait, auto-configuration is very difficult and complex. So in this paper, we try to propose a new mechanism for the auto-configuration in MANET. It is mainly based on the tree structure to generate the unique sequence number for each of nodes to guarantee the address conflict free. In order to avoid the DAD (Duplicate Address Detection), we import three root managing nodes. Each of them just handles one of three part of the whole of network and function some process, such as detecting the node which departs the network abruptly, initiating root managing node election, and managing the network merger

The Danish Eulerian Model (DEM) is a powerful air pollution model, designed to calculate the concentrations of various dangerous species over a large geographical region (e.g. Europe). It takes into account the main physical and chemical processes between these species, the actual meteorological conditions, emissions, etc. . This is a huge computational task and requires significant resources of storage and CPU time. Parallel computing is essential for the efficient practical use of the model. Some efficient parallel versions of the model were created over the past several years.A suitable parallel version of DEM by using the Message Passing Interface library (MPI) was implemented on two powerful supercomputers of the EPCC - Edinburgh, available via the HPC-Europa programme for transnational access to research infrastructures in EC: a Sun Fire E15K and an IBM HPCx cluster. Although the implementation is in principal, the same for both supercomputers, few modifications had to be done for successful porting of the code on the IBM HPCx cluster. Performance analysis and parallel optimization was done next. Results from benchmarking experiments will be presented in this paper.Another set of experiments was carried out in order to investigate the sensitivity of the model to variation of some chemical rate constants in the chemical submodel. Certain modifications of the code were necessary to be done in accordance with this task. The obtained results will be used for further sensitivity analysis studies by using Monte Carlo simulation.

An operator approach to multipoint Padé approximations
Authors: Maxim S. Derevyagin, Alexei S. Zhedanov
Venue: Journal of Approximation Theory (2009)

First, an abstract scheme of constructing biorthogonal rational systems related to some interpolation problems is proposed. We also present a modification of the famous step-by-step process of solving the Nevanlinna-Pick problems for Nevanlinna functions. The process in question gives rise to three-term recurrence relations with coefficients depending on the spectral parameter. These relations can be rewritten in the matrix form by means of two Jacobi matrices. As a result, a convergence theorem for multipoint Pade approximants to Nevanlinna functions is proved.
Forming Trust in Mobile Ad Hoc Network
Authors: Asmidar Abu Bakar, Jamalul-lail Abdul Manan
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 03 (2009)

Mobile ad-hoc network which is constructed via mobile nodes without the pre-registration of nodes have created problem in resource sharing. As nodes can join/leave the network randomly therefore nodes may not aware to which nodes is it connected with and this make resources been shared among anonymous nodes which can be trusted/not trusted. This has created unfavorable situation for private transaction. Hence a mechanism to formalize trustworthiness among these anonymous nodes is needed to make sure resources are shared among trusted nodes only. In this paper, we proposed a schema that can compute trust value among anonymous nodes. The schema is formed via direct and indirect approach. Parameters such as recommendation, reputation, knowledge, observation and context were used to evaluate the trust value. The result obtained from the calculation is then mapped with the access privileges to determine the action required.
A Context and Content-Based Routing Protocol for Mobile Sensor Networks
Authors: Gianpaolo Cugola, Matteo Migliavacca
Venue: Proceedings of the 6th European Conference on Wireless Sensor Networks (2009)

The need of monitoring people, animals, and things in general, brings to consider mobile WSNs besides traditional, fixed ones. Moreover, several advanced scenarios, like those including actuators, involve multiple sinks. Mobility and multiple sinks radically changes the way routing is performed, while the peculiarities of WSNs make it difficult to reuse protocols designed for other types of mobile networks.In this paper, we describe CCBR, a Context and Content-Based Routing protocol explicitly designed for multi-sink, mobile WSNs. CCBR adopts content-based addressing to effectively support the data-centric communication paradigm usually adopted by WSN applications. It also takes into account the characteristics (i.e., context) of the sensors to filter data.Simulations show that CCBR outperforms alternative approaches in the multi-sink, mobile scenarios it was designed for, while providing good performance in more traditional (fixed) scenarios.
The RavenClaw dialog management framework: Architecture and systems
Authors: Dan Bohus, Alexander I. Rudnicky
Venue: Computer Speech and Language (2009)

In this paper, we describe RavenClaw, a plan-based, task-independent dialog management framework. RavenClaw isolates the domain-specific aspects of the dialog control logic from domain-independent conversational skills, and in the process facilitates rapid development of mixed-initiative systems operating in complex, task-oriented domains. System developers can focus exclusively on describing the dialog task control logic, while a large number of domain-independent conversational skills such as error handling, timing and turn-taking are transparently supported and enforced by the RavenClaw dialog engine. To date, RavenClaw has been used to construct and deploy a large number of systems, spanning different domains and interaction styles, such as information access, guidance through procedures, command-and-control, medical diagnosis, etc. The framework has easily adapted to all of these domains, indicating a high degree of versatility and scalability.
Functional approach to turnkey system procurement
Authors: Wayne Churchman
Venue: Proceedings of the May 19-22, 1975, national computer conference and exposition (1975)

The advent of the low cost minicomputer has extended the computer into many new application areas. Minicomputer systems are used in manufacturing control, laboratory automation, and industrial data acquisition and control applications where the high cost of computers have traditionally prohibited their use. In many of these growing application areas, users want to purchase a fully developed hardware and software package which requires no further development and which provides guaranteed performance. This is the concept of the turnkey system. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

Towards experimental evaluation of explicit congestion control
Authors: Yueping Zhang, Saurabh Jain, Dmitri Loguinov
Venue: Computer Networks: The International Journal of Computer and Telecommunications Networking (2009)

Innovative efforts to provide a clean-slate design of congestion control for future high-speed heterogeneous networks have recently led to the development of explicit congestion control. These methods rely on multi-byte router feedback and aim to contribute to the design of a more scalable Internet of tomorrow. However, experimental evaluation and deployment experience with these approaches is still limited to either low bandwidth networks or simple topologies. In addition, all existing implementations are exclusively applicable to either rate- or window-based protocols and are unable to study performance of different protocols on a common platform. This paper aims to fill this void by designing a unified Linux implementation framework for both rate- and window-based methods that does not incur any interference with the system's network stack or applications. Using this implementation, we implement and reveal several key properties of four recent explicit congestion control protocols XCP, JetMax, RCP, and PIQI-RCP using Emulab's gigabit testbed with a ariety of simple yet representative network topologies. Our experiments not only confirm the known behavior of these methods, but also demonstrate their previously undocumented properties (e.g., RCP's transient overshoot under abrupt traffic load changes and JetMax's low utilization in the presence mice flows).
“Smart” TDDB algorithm for investigating degradation in high-κ gate dielectric stacks under constant voltage stress
Authors: Chadwin D. Young, Gennadi Bersuker, Joey Tun, Rino Choi, Dawei Heh, Byoung Hun Lee
Venue: Microelectronic Engineering (2009)

A new ''smart'' algorithm with adaptive testing is developed for automatically monitoring gate dielectric degradation during CVS using SILC. In this approach, stress current is monitored with a sampling rate as fast as ~2ms/point while SILC data are collected based on stress current changes and/or time intervals. This automated test was applied to study degradation of nMOS transistors with TiN/HfO"2 gate stacks where changes in the SILC data correlate directly with transitions in the stress current. From this SILC data, the differential resistance can be extracted and used to monitor conductivity throughout the degradation phase until breakdown.

The CineLingua Approach: Verbal and Non-verbal Features in Second Language Acquisition. Film Narrative to Anchor Comprehension and Production
Authors: Rosa Volpe
Venue: Verbal and Nonverbal Features of Human-Human and Human-Machine Interaction: COST Action 2102 International Conference, Patras, Greece, October 29-31, 2007. Revised Papers (2008)

This study has as a central focus a foreign language classroom environment that makes daily use of multimedia film lessons in the target language. More specifically this study explores whether first-semester, first-year college students of Italian will understand film narrative, and how, the comprehension of the film narrative will affect their written production. Eighty-one first year college students participated in this study. The results suggest that the Anchored Learning Group performed better than the Basic-Skills Learning Group in the comprehension tasks of the two film segments. The second experimental probe, consisting in a production task, shows that compared to the Basic-Skills Learning Group, the written productions of the Anchored Learning Group reflect far better the structure of the narrative discourse participants have been exposed to. On the occasion of this production task, students were required to write their essay using at least ten Italian verbs.
A Bionic Model for Human-like Machine Perception
Authors: Rosemarie Velik
Venue:  (2008)

Machine perception is a research field that is still in its infancy and is confronted with many unsolved problems. In contrast, humans generally perceive their environment without problems. These facts were the motivation to develop a bionic model for human-like machine perception, which is based on neuroscientific and neuro-psychological research findings about the perceptual system of the human brain. Having systems available that are capable of a human-like perception of their environment allow the automation of processes, which, today, require human observers and their cognitive abilities. As research results show, a technically functioning and implementable model of human-like perception does not only lead to more efficient machine perception systems but also to a better understanding of the perceptual system of the brain.
Association Classification Based on Compactness of Rules
Authors: Qiang Niu, Shi-Xiong Xia, Lei Zhang
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

Associative classification has high classification accuracy and strong flexibility. However, it still suffers from overfitting since the classification rules satisfied both minimum support and minimum confidence are returned as strong association rules back to the classifier. In this paper, we propose a new association classification method based on compactness of rules, it extends Apriori Algorithm，which considers the interestingness, importance, overlapping relationships among rules. At last, experimental results shows that the algorithm has better classification accuracy in comparison with CBA and CMAR are highly comprehensible and scalable.
Effective uses of FPGAs for brute-force attack on RC4 ciphers
Authors: Sammy H. M. Kwok, Edmund Y. Lam
Venue: IEEE Transactions on Very Large Scale Integration (VLSI) Systems (2008)

This paper presents an effective field-programmable gate array (FPGA)-based hardware implementation of a parallel key searching system for the brute-force attack on RC4 encryption. The design employs several novel key scheduling techniques to minimize the total number of cycles for each key search and uses on-chip memories of the FPGA to maximize the number of key searching units per chip. Based on the design, a total of 176 RC4 key searching units can be implemented in a single Xilinx XC2VP20-5 FPGA chip, which currently costs only a few hundred U.S. dollars. Operating at a 47-MHz clock rate, the design can achieve a key searching speed of 1.07 × 107 keys per second. Breaking a 40-bit RC4 encryption only requires around 28.5 h.
Computing Teichmüller Shape Space
Authors: Miao Jin, Wei Zeng, Feng Luo, Xianfeng Gu
Venue: IEEE Transactions on Visualization and Computer Graphics (2009)

Shape indexing, classification, and retrieval are fundamental problems in computer graphics. This work introduces a novel method for surface indexing and classification based on Teichmuller theory. The Teichmuller space for surfaces with the same topology is a finite dimensional manifold, where each point represents a conformal equivalence class, a curve represents a deformation process from one class to the other. We apply Teichmuller space coordinates as shape descriptors, which are succinct, discriminating and intrinsic; invariant under the rigid motions and scalings, insensitive to resolutions. Furthermore, the method has solid theoretic foundation, and the computation of Teichmuller coordinates is practical, stable and efficient. This work focuses on the surfaces with negative Euler numbers, which have a unique conformal Riemannian metric with -1 Gaussian curvature. The coordinates which we will compute are the lengths of a special set of geodesics under this special metric. The metric can be obtained by the curvature flow algorithm, the geodesics can be calculated using algebraic topological method. We tested our method extensively for indexing and comparison of about one hundred of surfaces with various topologies, geometries and resolutions. The experimental results show the efficacy and efficiency of the length coordinate of the Teichmuller space.
The Embedded Internet: TCP/IP Basics, Implementation and Applications
Authors: Sergio Scaglia
Venue:  (2007)

In The Embedded Internet Sergio Scaglia examines the techniques that programmers will need to learn to obtain internet connectivity for their embedded systems. Sometimes this will be relatively straight-forward, using TCP/IP stack implementations which already exist. Sometimes, this will be much more difficult, requiring whole new implementations to be developed. Either way, The Embedded Internet will be the ideal starting place for programmers to learn and develop these skills. The book is structured in three parts. The first part comprehensively covers TCP/IP. This gives the reader the necessary background knowledge of the internet that they will need when considering embedded systems connectivity. The second part details how to implement embedded internet systems. The third and final part gives a conceptual overview of just a handful of the countless ways in which internet connectivity can benefit an embedded system.
Thermal-aware post compilation for VLIW architectures
Authors: Wen-Wen Hsieh, TingTing Hwang
Venue: Proceedings of the 2009 Asia and South Pacific Design Automation Conference (2009)

Development of a thermal management method to reduce hotspots and to balance the temperature distribution has become an important issue. In this paper, we propose a static thermal management technique at compiler level. The target machine is a VLIW architecture where the compiler is required to schedule instructions to achieve instruction level parallelism (ILP). Two technique are proposed. The first one is register binding to balance the temperature of the register file by taking both spatial and temporal thermal information into consideration. The second one is forwarding methods including forwarding-aware architecture and instruction scheduling to reduce the access count of register file. The experimental results show that by combining the two techniques, the peak temperature reduction can reach 7.89 (&deg;C) in the best case and 7.22 (&deg;C) in average with only 0.9% performance penalty in average.
Autonomic QoS control in enterprise Grid environments using online simulation
Authors: Ramon Nou, Samuel Kounev, Ferran Julií, Jordi Torres
Venue: Journal of Systems and Software (2009)

As Grid Computing increasingly enters the commercial domain, performance and quality of service (QoS) issues are becoming a major concern. The inherent complexity, heterogeneity and dynamics of Grid computing environments pose some challenges in managing their capacity to ensure that QoS requirements are continuously met. In this paper, a comprehensive framework for autonomic QoS control in enterprise Grid environments using online simulation is proposed. This paper presents a novel methodology for designing autonomic QoS-aware resource managers that have the capability to predict the performance of the Grid components they manage and allocate resources in such a way that service level agreements are honored. Support for advanced features such as autonomic workload characterization on-the-fly, dynamic deployment of Grid servers on demand, as well as dynamic system reconfiguration after a server failure is provided. The goal is to make the Grid middleware self-configurable and adaptable to changes in the system environment and workload. The approach is subjected to an extensive experimental evaluation in the context of a real-world Grid environment and its effectiveness, practicality and performance are demonstrated.
