IBM information network performance and availability measurement
Authors: Richard C. Soucy, Richard M. Bailey
Venue: Proceedings of the May 16-19, 1983, national computer conference (1983)

A key requirement in the network service business is that specified service levels be managed to the end user's satisfaction. The capability to measure and report end user response time and availability is essential. This paper will describe measurement techniques that were developed to track these important service level attributes in the IBM Information Network (IBM/IN). These techniques apply to most complex SNA networks.

Authors: Fadila Khadar, David Simplot-Ryl
Venue: Proceedings of the tenth ACM international symposium on Mobile ad hoc networking and computing (2009)

We describe how to build a relative neighborhood graph on a real network without any positioning system. We base the computation of the RNG on a RSSI weight function and show how to adapt transmission power to the resulting graph.
(In)Security of an Efficient Fingerprinting Scheme with Symmetric and Commutative Encryption of IWDW 2005
Authors: Raphael C. Phan, Bok-Min Goi
Venue: Proceedings of the 6th International Workshop on Digital Watermarking (2008)

We analyze the security of a fingerprinting scheme proposed at IWDW 2005. We show two results, namely that this scheme (1) does not provide seller security: a dishonest buyer can repudiate the fact that he redistributed a content, and (2) does not provide buyer security: a buyer can be framed by a malicious seller.
An efficient method of estimating the true value of a population characteristic from its discrepant estimates
Authors: P. A. V. B. Swamy, Jatinder S. Mehta, I-Lok Chang, T. S. Zimmerman
Venue: Computational Statistics Data Analysis (2009)

A fruitful method of pooling data from disparate sources, such as a set of sample surveys, is developed. This method proceeds by finding the first two moments of two conditional distributions derived from a joint distribution of two sample estimators of employment for each of several geographical areas. The nature of the two estimators is such that one of them can yield a better estimate of national employment than the other. The regression of the former estimator on the latter estimator with stochastic intercept and slope is used to generate an improved estimator that is equal to bias- and error-corrected estimator for each area with probability 1. This analysis is extended to cases where more than two estimates of employment are available for each area.

Feature Extraction Using Wavelet Transform for Radar Emitter Signals
Authors: Taowei Chen, Weidong Jin, Zhenxing Chen
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 01 (2009)

In this paper, an approach for intra-pulse feature extraction of radar emitter signals is proposed based on wavelet transform. On the basis of the multi-resolution characteristics of wavelet transform, two energy entropies, as a two-dimensional feature vector to reveal the difference of radar modulation signals, are respectively extracted from approximation coefficient and multi-scale detail coefficients preserved through inter-scale correlations denoise in wavelet transform domain. In order to demonstrate the effectiveness and feasibility of the proposed approach, computer simulations indicates that the entropy features of ten typical radar emitter signals extracted by wavelet transform have good performance of clustering and suppressing noise when SNR is 0dB. In addition, proposed approach can separate the same modulation signals with different parameters.
Brief paper: Enlarging the domain of attraction of stable MPC controllers, maintaining the output performance
Authors: Alejandro H. González, Darci Odloak
Venue: Automatica (Journal of IFAC) (2009)

This work presents an alternative way to formulate the stable Model Predictive Control (MPC) optimization problem that allows the enlargement of the domain of attraction, while preserving the controller performance. Based on the dual MPC that uses the null local controller, it proposed the inclusion of an appropriate set of slacked terminal constraints into the control problem. As a result, the domain of attraction is unlimited for the stable modes of the system, and the largest possible for the non-stable modes. Although this controller does not achieve local optimality, simulations show that the input and output performances may be comparable to the ones obtained with the dual MPC that uses the LQR as a local controller.
An efficient clustering framework for relevant web information
Authors: Ok-Ran Jeong, Sang-Won Lee
Venue: Proceedings of the 3rd International Conference on Ubiquitous Information Management and Communication (2009)

As the amount of available information on the Internet grows, it is becoming increasingly difficult for users to find information that is relevant to their needs. Against this backdrop, a need for an automated tool that can find information quickly and easily has surfaced. In this paper, we propose a Clustering Framework for crawling and clustering the necessary information from Web pages. The proposed clustering framework consists of three modules: a preprocessing module, clustering module and community module. Using this framework, we are able to automatically cluster Web pages according to topic and rank them in terms of relevance. We describe this framework, and show the results of our preliminary validation work.

In the area of health care and sports in recent years a variety of mobile applications have been established. Mobile devices are of emerging interest due to their high availability and increasing computing power in many different health scenarios. In this paper we present a scalable secure sensor monitoring platform (SSMP) which collects vital data of users. Vital parameters can be collected by just one single sensor or in a multi-sensor configuration. Nowadays a wide spectrum of sensors is available which provide wireless connectivity (e.g. Bluetooth). Vital data can then easily be transmitted to a mobile device which subsequently transmits these data to an eHealth portal. There are already solutions implementing these capabilities, however privacy aspects of users are very often neglected. Since health data may enable people to draw potentially compromising conclusions (e.g. insurance companies), it is absolutely necessary to design an enhanced security concept in this context. To complicate matters further, the trustworthiness of providers which are operating with user's health data can not be determined by users a priori. This means that the security concept implemented by the provider may bear security flaws. Additionally there is no guarantee that the provider preserves the users privacy claims. In this work we propose a security concept incorporating privacy aspects using mobile devices for transferring and storing health data at a portal. In addition, the concept guarantees anonymity in the transfer process as well as for stored data at a service provider. Hence, insider attacks based on stored data can be prevented.
Landing Page 101: Learn the Top 100 Tips to Landing Pages - Improve your ROI with Quality Landing Pages, Now Create Landing Pages that Truly Convert
Authors: James Moore
Venue:  (2008)

In online marketing a landing page, sometimes known as a lead capture page, is the page that appears when a potential customer clicks on an advertisement or a search-engine result link. The page will usually display content that is a logical extension of the advertisement or link, and that is optimized to feature specific keywords or phrases for indexing by search engines.In pay per click (PPC) campaigns, the landing page will also be customized to measure the effectiveness of different advertisements. By adding a parameter to the linking URL, marketers can measure advertisement effectiveness based on relative click-through rates.When you build a landing page, and you are going to invest time and money to get people to visit it, it makes sense to optimize that page to accomplish optimal ROI.This book answers 100 most asked questions like: How long does a landing page last before you change it to a better one? And do you have a different landing page for every single ad, every single offer? Why not?This book covers all the basics on building specific measurable offers, not generalities. This book covers measuring if they're working or not, improving the metrics and make them work better. Landing pages is direct marketing, read this book if you have a website: everyone with a website is a direct marketer.
Transition systems specified as a communication tool for e-learning
Authors: Bogdan A. Brumar, Emil M. Popa, Iulian Pah, Dan Chiribuca
Venue: Proceedings of the 12th WSEAS international conference on Computers (2008)

Due to the dynamic nature of the computing objects represented, the semantics of the specification languages used to formalize systems will be a transition system performing computation actions, while the syntax will be the linguistic expression of the actions performed by the transition system. Computing objects manipulated in computer science bear a lot of similarities with the mathematical objects produced by the systems discussed so far they also are very different. The concept of language is regarded as a communication tool that allows language users to develop knowledge, while interacting with their universe of discourse, and to communicate with each other, while exchanging knowledge, in that case for e-learning systems. The results presented here have as initial point [1], [7].
Mathematical study of h-index sequences
Authors: L. Egghe
Venue: Information Processing and Management: an International Journal (2009)

This paper studies mathematical properties of h-index sequences as developed by Liang [Liang, L. (2006). h-Index sequence and h-index matrix: Constructions and applications. Scientometrics,69(1), 153-159]. For practical reasons, Liming studies such sequences where the time goes backwards while it is more logical to use the time going forward (real career periods). Both type of h-index sequences are studied here and their interrelations are revealed. We show cases where these sequences are convex, linear and concave. We also show that, when one of the sequences is convex then the other one is concave, showing that the reverse-time sequence, in general, cannot be used to derive similar properties of the (difficult to obtain) forward time sequence. We show that both sequences are the same if and only if the author produces the same number of papers per year. If the author produces an increasing number of papers per year, then Liang's h-sequences are above the ''normal'' ones. All these results are also valid for g- and R-sequences. The results are confirmed by the h-, g- and R-sequences (forward and reverse time) of the author.
Data clouds: summarizing keyword search results over structured data
Authors: Georgia Koutrika, Zahra Mohammadi Zadeh, Hector Garcia-Molina
Venue: Proceedings of the 12th International Conference on Extending Database Technology: Advances in Database Technology (2009)

Keyword searches are attractive because they facilitate users searching structured databases. On the other hand, tag clouds are popular for navigation and visualization purposes over unstructured data because they can highlight the most significant concepts and hidden relationships in the underlying content dynamically. In this paper, we propose coupling the flexibility of keyword searches over structured data with the summarization and navigation capabilities of tag clouds to help users access a database. We propose using clouds over structured data (data clouds) to summarize the results of keyword searches over structured data and to guide users to refine their searches. The cloud presents the most significant words associated with the search results. Our keyword search model allows searching for entities than can span multiple tables in the database rather than just tuples, as existing keyword searches over databases do. We present several methods to compute the scores both for the entities and for the terms in the search results. We describe algorithms for keyword searches with data clouds and we present our system, CourseCloud, that offers a unified search and browse interface to a course database. We present experimental results showing (a) the appropriateness of the methods used for scoring terms, (b) the performance of the proposed algorithms, and (c) the effectiveness of CourseCloud compared to typical search and browse interfaces to a course database.
Model-Based Software Engineering and Process-Aware Information Systems
Authors: Ekkart Kindler
Venue: Transactions on Petri Nets and Other Models of Concurrency II: Special Issue on Concurrency in Process-Aware Information Systems (2009)

Today, there are many graphical formalisms for modelling software--among others the Unified Modeling Language (UML). And there are different technologies that automatically generate code from such models. We call these as well as any approach that takes models more seriously than just a sketch or an illustration Model-based Software Engineering (MBSE). Most of today's code generation approaches, however, focus on standard behaviour; application specific behaviour often still needs to be programmed manually. The ultimate goal of MBSE, however, is to generate all code automatically.In the field of Process-aware Information System (PAIS) and workflow management, models have been in the focus right from the beginning. What is more, the models were used to define and enact application specific behaviour or business logic by providing process models. This way, they are one of the successful precursors of Model-based Software Engineering.In this paper, we will give an overview of the concepts and technologies in MBSE, and its main ideas, principles, and concepts. We will point out some differences to PAIS, but also some common ground, and we show how both fields could benefit from each other. This way, we want to start bridging the gap between MBSE and PAIS .
e-revenue administration in Nepal
Authors: Ganesh Prasad Adhikari
Venue: Proceedings of the 2nd International Conference on Theory and Practice of Electronic Governance (2008)

Government of Nepal has prepared an e-Government Master Plan (e-GMP) to increase the efficiency of government services with the effective use of Information, Communication and Technology (ICT). The Government is making efforts for successful implementation of this plan. E-revenue administration is one of the systems dedicated to provide quality services to the public; specifically the tax payers using IT as a major tool. Inland Revenue Department (IRD) of Government of Nepal is the agency responsible for the implementation of the e-Revenue Administration. IRD is primarily responsible for enforcement of Tax Laws, administration and monitoring the non-tax revenues of the Government of Nepal. The e-Revenue Administration initiative of the IRD commenced in 2006 has produced successful ICT projects with resulting applications enjoying significant citizen uptake. These applications include: e-PAN (Electronic Permanent Account Number) System; Value Added Tax (VAT) Assessment/Collection; Income Tax Assessment/Collection Services; Revenue Accounting System (RAS); e-Estimated Income Tax Return System; Check point Entry System; Third Party data including import data from customs and SMS System. This paper presents an overview of these initiatives, briefly highlights success factors and comments on improvement.
Sound Field Reproduction System Using Simultaneous Perturbation Method
Authors: Kazuya Tsukamoto, Yoshinobu Kajikawa, Yasuo Nomura
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

In this paper, we propose a novel sound field reproduction system that uses the simultaneous perturbation (SP) method as well as two fast convergence techniques. Sound field reproduction systems that reproduce any desired signal at listener's ear generally use fixed preprocessing filters that are determined by the transfer functions from loudspeakers to control points in advance. However, control point movement results in severe localization errors. Our solution is a sound field reproduction system, based on the SP method, which uses only an error signal to update the filter coefficients. The SP method can track all control point movements but suffers from slow convergence. Hence, we also propose two methods that offer improved convergence speeds. One is a delay control method that compensates the delay caused by back-and-forth control point movements. The other is a compensation method that offsets the localization error caused by head rotation. Simulations demonstrate that the proposed methods can well track control point movements while offering reasonable convergence speeds.

Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

With the progress in science and technology, the modernization manufacturing process have become increasingly demanding in CNC. In this paper, it has chosen Permanent Magnet Synchronous Motor (PMSM) and Digital Signal Processor (DSP) to design the servo control system for Open-CNC. Based on the analysis of the Open-CNC structure, movement principle, fundamental theories of vector control, it has built the PMSM vector control module in MATLAB, and introduces the control principle in detail. In addition, a new and high-efficiency DSP developing flow is introduced. The flow realizes the auto -generation of DSP code with the use of MATLAB, Simulink, Real-Time Workshop, DSP and TIs development environment-CCS. It realizes the integration from design to implementing, and shortens the developing period greatly. The PMSM control system designed using this flow now has worked well on the TMS320F2812EVM. At last, it gives the communications circuits between PC and DSP.
Research on Tactical Communication Network Simulation Training Based on CGN
Authors: Zhi-chun Gan, Zhao-yong Fan, Jian-jun Shen
Venue: Proceedings of the 2009 International Conference on Computer Modeling and Simulation (2009)

Training for Tactical Communication Network (TCN) and its various communication equipments needs support of realistic dynamic networking environment. To meet the requirement, the concept of Computer Generated Network (CGN) was advanced, which borrowed the idea of Computer Generated Forces (CGF). According to this, the CGN principle frame was designed and a realization framework for network simulator based on CGN was brought out. Then three different modes for TCN simulation training based on the concept of CGN were put forward, namely, all-element virtual mode, part-element virtual mode and all-element actual mode. The research introduced new method and novel idea for TCN simulation training.
Concern-oriented analysis and refactoring of software architectures using dependency structure matrices
Authors: Bedir Tekinerdogan, Frank Scholten, Christian Hofmann, Mehmet Aksit
Venue: Proceedings of the 15th workshop on Early aspects (2009)

Current scenario-based architecture analysis methods analyze the architecture with respect to scenarios that relate to stakeholder concerns. Albeit the primary motivation is to analyze the impact of stakeholders' concerns, it appears that concerns are not explicitly represented as first class abstractions. The lack of an explicit notion of concern in scenario-based analysis approaches can result in an incomplete analysis because scenarios are too specific and can only partially represent the concerns. We propose the concern-oriented architecture analysis method (COSAAM) that builds on scenario-based approaches but includes an explicit notion of concern in the analysis. COSAAM applies Dependency Structure Matrices (DSMs) to represent and analyze the dependencies among scenarios, concerns and architectural elements. Further, COSAAM extends DSMs by introducing explicit DSM patterns and heuristic rules for analyzing the impact of concerns on the architecture and for supporting the refactoring of the architecture.
Towards Utilizing Open Data for Interactive Knowledge Transfer
Authors: Monika Steinberg, Jürgen Brehm
Venue: Proceedings of the 2009 International Conference on Mobile, Hybrid, and On-line Learning (2009)

Increasing heterogeneous Open Data is an ongoing trend in the current Social Semantic Web (s2w). Generic concepts and how-tos for higher-layered reuse of the arbitrary information overload for interactive knowledge transfer and learning - mentioning the Internet of Services (IoS) - are not covered very well yet. For further, directed use of distributed services and sources, inquiry, interlinking, analysis, machine- and human-interpretable representation are as essential as lightweight user-oriented interoperation and competency in handling. In the following we introduce the qKAI application framework (qualifying Knowledge Acquisition and Inquiry) - a service-oriented, generic and hybrid approach combining knowledge related offers for convenient reuse and tweaking them with interaction for improved access with rich user experience. qKAI aims at closing some residual gaps between the "sophisticated" Semantic Web and "hands-on" Web 2.0 enabling loose-coupled knowledge and information services focussed on knowledge life cycles, learning aspects and handy user interaction.
