Numerical implementation of a class of infinite-dimensional primal-dual algorithms and control applications
Authors: Thanasak Mouktonglang
Venue:  (2004)

This Thesis is devoted to primal-dual algorithms in the infinite-dimensional setting. We consider a class of infinite-dimensional optimization problems and its applications to optimal control problems. A primal-dual algorithm based on Nesterov Todd direction is implemented. We apply this algorithm to two important control problems: multi-criteria linear-quadratic control problems and linear-quadratic control problems with quadratic constraints. Numerical experiments confirm very fast convergence of the algorithm which is predicted by the theory based on the concept of infinite-dimensional Jordan algebras. Necessary theoretical results have been developed. To the best of our knowledge this is the first implementation of this class of algorithms.
Improving Scalability and Robustness of NQOSP Algorithm in Dynamic Traffic's Network
Authors: Said Hoceini, Abdelhamid Mellouk, Yacine Amirat
Venue: Proceedings of the Joint International Conference on Autonomic and Autonomous Systems and International Conference on Networking and Services (2005)

This paper improves scalability and robustness of our earlier developed approach based on adaptive algorithm for packet routing using reinforcement learning called N Q-routing Optimal Shortest Paths (NQOSP). In contrast with other algorithms that are also based on Reinforcement Learning (RL) methods, the N Q-Routing Optimal Shortest Paths is based on a multi-paths routing technique combined with the QRouting algorithm. In this case, the exploration space is limited to N-best non loop paths in term of hops number (number of routers in a path) leading to a substantial reduction of convergence time. Moreover, each router uses an on line learning module to optimize the path in terms of average packet delivery time. In this paper, we focus on improving the scalability and robustness of our earlier developed approach. The performance of NQOSP is evaluated experimentally with OPNET simulator for different levels of traffic's load and compared to standard shortest path, N-best algorithm and Q-routing algorithms on large interconnected network. Our Approach prove superior to a classical algorithms and are able to route efficiently even when critical aspects, such as the link broken network, are allowed to vary dynamically.

Authors: Paul Lapides, Ehud Sharlin, Mario Costa Sousa, Lisa Streit
Venue: Proceedings of the First IEEE International Workshop on Horizontal Interactive Human-Computer Systems (2006)

We present the 3D Tractus: a simple and inexpensive system for interaction and exploration of three-dimensional (3D) data. The device is based on a traditional drawing boardlike mechanical structure that can be easily moved up and down while its surface height is being tracked using a simple sensor. Users interact with a tablet or tablet PC that rests on the surface while simultaneously changing its height. The result is direct mapping of virtual and physical spaces allowing intuitive 3D interaction and data exploration. The 3D Tractus allows us to investigate novel 3D interaction techniques based on sketching and drawing as well as intuitive visual indicators and GUI layouts. The 3D Tractus' simple design concept can be easily adapted to other tabletop systems and the simple nature of the physical interaction allows the design of various exciting applications. We detail here the design and development of the 3D Tractus hardware and software as well as preliminary evaluation of a 3D drawing and sketching application realized using the new tabletop interface.

Authors: Xiaojun Bi, Yuanchun Shi, Xiaojie Chen, PeiFeng Xiang
Venue: Proceedings of the 13th annual ACM international conference on Multimedia (2005)

We present the uPen, a laser pointer combined with a contact-pushed switch, three press buttons and a wireless communication module. This novel interaction device allows users to interact on large displays at a distance or directly on the surface with full-function of mouse. Onboard software enable the uPen system to identify different users and provide personalized services to them, such as associating users with corresponding privileges, giving access to each participant's private content (e.g., home pages, personal calendars). Additionally, with our two-step association method, the uPen system has the ability to distinguish strokes of different uPens working simultaneously and support multi-user simultaneous interaction. A prototype system has been implemented in our Smart Classroom [1]. And user studies show the benefit of using it.
Merging Interface Schemas on the Deep Web via Clustering Aggregation
Authors: Wensheng Wu, AnHai Doan, Clement Yu
Venue: Proceedings of the Fifth IEEE International Conference on Data Mining (2005)

We consider the problem of integrating a large number of interface schemas over the Deep Web, The scale of the problem and the diversity of the sources present serious challenges to the conventional manual or rule-based approaches to schema integration. To address these challenges, we propose a novel formulation of schema integration as an optimization problem, with the objective of maximally satisfying the constraints given by individual schemas. Since the optimization problem can be shown to be NP-complete, we develop a novel approximation algorithm LMax, which builds the unified schema via recursive applications of clustering aggregation. We further extend LMax to handle the irregularities frequently occurring among the interface schemas. Extensive evaluation on real-world data sets shows the effectiveness of our approach.
A Production Analysis Simulation System (PASS)
Authors: Donald F. Blumberg
Venue: ACM SIGSIM Simulation Digest (1979)

The Production Analysis Simulation System, PASS, is a computer-based simulation system designed to represent the key elements of electronics, electro-mechanical or mechanical assembly oriented manufacturing operations. PASS provides management with a precise mechanism:&bull; <u>To evaluate the efficiency and/or capacity</u> of these operations&bull; To generate <u>estimates of the impact of a wide variety of strategic and tactical changes</u> in the production systemThe PASS simulation produces a set of detailed measurements of each alternative manufacturing strategy and tactic. These measurements enable the manufacturing manager to assess the trade-offs between these alternatives. The following standard measurements are generated by PASS:&bull; <u>Finished goods and work-in-process inventory levels</u>&bull; <u>Manpower utilization and costs</u>&bull; <u>Stockout levels</u> including- a record of the percentage of late deliveries for each assembly, sub-assembly, accessory, etc.- for all late orders, a distribution describing the number of days late.&bull; A detailed record of the <u>manufacturing and manpower planning process</u> is also represented.In summary, PASS is a simulation system that provides answers to "WHAT IF .... ?" questions about alternative manufacturing operating strategies such as changes in product flow, cycle times, production to order versus production to inventory, etc. These answers are produced in the form of detailed, quantitative reports which provide top management with a precise dollars and cents, hours and minutes report of the impact of each alternative manufacturing strategy and tactic under evaluation.

ZKp Based Identification Protocol on Conic Curve in Distributed Environment
Authors: Zhe YANG, Min LIU
Venue: Proceedings of the The Fifth International Conference on Computer and Information Technology (2005)

This paper proposed a protocol for zero-knowledge proof of identity based on ElGamal on conic. It is more appropriate than the traditional identity protocol in distributed environment without trusted third parties. The security of this protocol relies on the discrete logarithm problem on conic over finite fields. Compared with those identification protocols implemented on elliptic curve, this protocol can be designed and implemented easier. And compared with that security lies on disassemble a large number, it runs faster. Corresponding to the simple version, a parallel version is presented subsequently. The characteristic of ZKp and security of the simple version is proved. The "soundness", "completeness", and amount of computation are also analyzed. A simple solution considering ttimeout is proposed to prevent a potential leak of our protocol.
PhotoRouter: destination-centric mobile media messaging
Authors: Shane Ahern, Simon King, Hong Qu, Marc Davis
Venue: Proceedings of the 13th annual ACM international conference on Multimedia (2005)

The number of people using cameraphones is growing by tens of millions every month. Yet the majority of cameraphone users have difficulty transferring photos off their phone and sharing them with others. PhotoRouter is a software application for cameraphones that makes the photo sharing process destination-centric by allowing users to focus on who the photo should go to, not how it needs to get there. Attempting to produce an application which meets user needs better than current, technology-centric cameraphone photo sharing applications, we designed PhotoRouter. In this paper we describe PhotoRouter's user interface innovations that we will show in our technical demonstration.
FPGA-Based Content Protection System for Embedded Consumer Electronics
Authors: Hiroyuki Yokoyama, Kenji Toda
Venue: Proceedings of the 11th IEEE International Conference on Embedded and Real-Time Computing Systems and Applications (2005)

We propose a new architecture for a content protection system that conceals confidential data and algorithms in an FPGA as electrical circuits. This architecture is designed for a client-server type on-line contents distribution services. The key component of this architecture is the digital content security circuit that is dynamically configured on the FPGA and performs the signal processing such as certification and decryption for replaying digital contents. The digital content security circuit is composed of two different circuits. One is the content-specific circuit that is built from the configuration data generated by the server. This circuit is specialized for each item of digital content. The other is the terminal built-in circuit that is uniquely programmed and implemented for each terminal, and is not open for the others. The content-specific circuit properly works only if it is combined with the terminal built-in circuit of the authorized client. We prototype and demonstrate a proof-of-concept model of the FPGA-based content protection system applicable to embedded consumer electronics such as set top boxes and cell phones.
Modelling and design considerations on CML gates under high-current effects: Research Articles
Authors: M. Alioto, G. Palumbo
Venue: International Journal of Circuit Theory and Applications (2005)

In this paper, the effect of the transit time degradation of bipolar transistors on the power-delay trade-off in CML gates and their design is dealt with. A delay model which accounts for the transit time increase due to the high bias current values used in high-speed applications is derived by generalizing an approach previously proposed by the same authors (IEEE Trans. CAD 1999; 18(9):1369&ndash;1375; Model and Design of Bipolar and MOS Current&mdash;Mode Logic (CML, ECL and SCL Digital Circuits), Kluwer Academic Publisher: Dordrecht, 2005). The resulting closed-form delay expression is achieved by properly simplifying the SPICE model, and has an explicit dependence on the bias current which determines the power consumption of CML gates. Accordingly, the delay model is used to gain insight into the power-delay trade-off by considering the effect of the transit time degradation in high-speed designs. In particular, the cases where such effects can be neglected are identified, to better understand how the transit time degradation affects the performance of CML gates for current bipolar technologies.The proposed model has a simple and compact expression, thus it turns out to be suitable for pencil-and-paper evaluations, as well as fast timing analysis. Simulations of CML circuits with a 20-GHz bipolar process show that the model has a very good accuracy in a wide range of current and loading conditions. Copyright &copy; 2005 John Wiley & Sons, Ltd.
A User-centered Look at Glyph-based Security Visualization
Authors: Anita Komlodi, Penny Rheingans, Utkarsha Ayachit, John R. Goodall, Amit Joshi
Venue: Proceedings of the IEEE Workshops on Visualization for Computer Security (2005)

This paper presents the Intrusion Detection toolkit (IDtk), an information Visualization tool for intrusion detection (ID). IDtk was developed through a user-centered design process, in which we identi- fied design guidelines to support ID users. ID analysts protect their networks by searching for evidence of attacks in ID system output, firewall and system logs, and other complex, textual data sources. Monitoring and analyzing these sources incurs a heavy cognitive load for analysts. The use of information visualization techniques offers a valuable addition to the toolkit of the ID analyst. Several visualization techniques for ID have been developed, but few usability or field studies have been completed to assess the needs of ID analysts and the usability and usefulness of these tools. We intended to fill this gap by applying a user-centered design process in the development and evaluation of IDtk, a 3D, glyph-based visualization tool that gives the user maximum flexibility in setting up how the visualization display represents ID data. The user can also customize whether the display is a simple, high-level overview to support monitoring, or a more complex 3D view allowing for viewing the data from multiple angles and thus supporting analysis and diagnosis. This flexibility was found crucial in our usability evaluation. In addition to describing the tool, we report the findings of our user evaluation and propose new guidelines for the design of information visualization tools for ID.

Authors: Jaan Raik, Peeter Ellervee, Valentin Tihhomirov, Raimund Ubar
Venue: Proceedings of the 8th Euromicro Conference on Digital System Design (2005)

Current paper presents new alternatives for accelerating the task of fault simulation for sequential circuits by hardware emulation on FPGA. Fault simulation is an important subtask in test pattern generation and it is frequently used throughout the test generation process. The problems associated to fault emulation for sequential circuits are explained and alternative implementations are discussed. An environment for hardware emulation of fault simulation is presented. It incorporates hardware support for fault dropping. The proposed approach allows simulation speed-up of 40 to 500 times as compared to the state-of-the-art in fault simulation. Average speedup provided by the method is 250 that is about an order of magnitude higher than previously cited in the literature. Based on the experiments, we can conclude that it is beneficial to use emulation when large numbers of test vectors is required.
Interactive Web Service Choice-Making Based on Extended QoS Model
Authors: Mou Yu-jie, Cao Jian, Zhang Shen-sheng, Zhang Jian-hong
Venue: Proceedings of the The Fifth International Conference on Computer and Information Technology (2005)

Quality of Service is a key factor in web service advertising, choosing and runtime monitoringwhich is multi-faceted, fuzzy and dynamic. Current researches on web service QoS focus on implementation level performance assurance, ignoring domain specific metrics at application level which are also very important to service users. Industry web service standards lack of QoS expressions, and the support for QoS based service choice-making is very limited. An extended web service QoS model is proposed. Web service QoS metrics are evaluated dynamically according to the service context and the overall QoS is evaluated from multiple metrics according to a configurable fuzzy synthetic evaluation system. A QoS requirement description model is defined to express user's flexible demands on service's performance. An interactive web service choice-making process is also provided, which includes QoS as a key factor.

Authors: R. Shantha Selva Kumari, V. Sadasivam
Venue: Proceedings of the Sixth International Conference on Computational Intelligence and Multimedia Applications (2005)

Wavelets have emerged as powerful tools for signal coding. In this paper embedded lossless Wavelet based coder with hybrid bit scan ning is used for ECG signal coding. Experimental results show that this algorithm outperforms than other coders such as Djohn, EZW, SPIHT, LJPEG etc exits in the literature in terms of coding efficiency by successive partitioned the wavelet coefficients in the space frequency domain and sent them using hybrid bit scanning. Since no Zero tree exists th is coder is significantly more efficient in compression, simple in implementation and in computation than the previously proposed coders. This algorithm is tes ted for thirty seven different records from MIT -BIH arrhythmia database and obtained an average percent root mean square difference as around 0.0502% to 3.5399% for an average compression ratio of 1.5:1 to 25.1429:1 and for an average bit rate of 2552.7bps to 254.5bps. A compression ratio of 8.0688:1 is achieved for MIT -BIH arrhythmia database record 117 with a percent mean square difference as 0.5183% and bit rate as 909.8bps using Bior6.8 wavelet. All clinical information is preserved after compression an d this makes the algorithm an attractive choice for use in portable heart monitoring systems.

A Reputation Management System in Structured Peer-to-Peer Networks
Authors: So Young Lee, O-Hoon Kwon, Jong Kim, Sung Je Hong
Venue: Proceedings of the 14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise (2005)

Since there is no method to verify the trustworthiness of shared files in P2P systems, malicious peers can spread untrustworthy files to the system. In order to prevent these untrustworthy files from spreading, we propose an effective reputation management system using peer reputation and file reputation together in DHT-based structured P2P networks. Simulation results show that the proposed system works better in preventing untrustworthy files from spreading than existing systems even in cases of allowing malicious peers to change their identities.
Security, Wiretapping, and the Internet
Authors: Susan Landau
Venue: IEEE Security and Privacy (2005)

Wiretaps have been used since the invention of the telegraph and have been a legal element of the U.S. law-enforcement arsenal for over a quarter century.In 1994, in keeping with law enforcement's efforts to have laws stay current with changing technologies, Congress passed the Communications Assistance for Law Enforcement Act (CALEA).This controversial law, which mandated that digitally-switched telephone networks must be built wiretap compatible, was not easily implemented.Now, in a move that may prove dangerous to national security, the FBI is seeking to extend CALEA to Voice over IP (VoIP).In this paper, I discuss national-security risks such an extension poses.
Proposal of two-stage patent retrieval method considering the claim structure
Authors: Hisao Mase, Tadataka Matsubayashi, Yuichi Ogawa, Makoto Iwayama, Tadaaki Oshio
Venue: ACM Transactions on Asian Language Information Processing (TALIP) (2005)

The importance of patents is increasing in global society. In preparing a patent application, it is essential to search for related patents that may invalidate the invention. However, it is time-consuming to identify them among the millions of patents. This article proposes a patent-retrieval method that considers a claim structure for a more accurate search for invalidity. This method uses a claim text as input; it consists of two retrieval stages. In stage 1, general text analysis and retrieval methods are applied to improve recall. In stage 2, the top N documents retrieved in stage 1 are rearranged to improve precision by applying text analysis and retrieval methods using the claim structure. Our two-stage retrieval introduces five precision-oriented analysis and retrieval methods: query-term extraction from a portion of a claim text that describes the characteristics of a claim; query term-weighting without term frequency; query term-weighting with &ldquo;measurement terms&rdquo;; text retrieval using only claims as a target; and calculating the relevant score by &ldquo;partially&rdquo; adding scores in stage 2 to those in stage 1. Evaluation results using test sets of the NTCIR4 Patent Retrieval Task show that our methods are effective, though the degree of the effectiveness varies depending on the test sets.

S-RaP: A Concurrent Prototyping Process for Refining Workflow-Oriented Requirements
Authors: Xiping Song, Gilberto Matos, Beatrice Hwong, Arnold Rudorfer, Christopher Nelson
Venue: Proceedings of the 13th IEEE International Conference on Requirements Engineering (2005)

This paper defines a highly concurrent, yet integrated software prototyping process for defining requirements. The process is particularly aimed at developing userinterface intensive, workflow-centered software. The Software Engineering Department and User Interface Design Center at Siemens Corporate Research (SCR) have successfully practiced this process in prototyping a healthcare information system over the last year to identify a set of preliminary functional requirements for the corresponding product. The prototype developed is intended to be of high quality, customizable and thus it can aid the communication between a company¿s marketing team and Siemens customers to further refine the product requirements. Our experience with this process demonstrates that it is feasible and effective to carry out the requirements definition and prototyping in a highly concurrent fashion given stable prototype software architecture and the readily available domain knowledge.
