A Novel Shared Path Protection Scheme for Reliability Guaranteed Connection
Authors: Jijun Zhao, Weiwei Bian, Lirong Wang, Sujian Wang
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

In this paper, we study the shared path protection (SPP) problem in wavelength division multiplexing (WDM) optical networks, and propose a novel SPP algorithm with differentiated reliability (DiR) called SPP-DiR. Differing from previous work, SPP-DiR algorithm effectively adapts to the diversity demands of customer requests and has higher resource utilization than SPP algorithm. Therefore, SPP-DiR algorithm outperforms the previous work. Simulation results have shown to be promising.
Scalar multiplier rules in set-valued optimization
Authors: Elvira Hernández, Luis Rodríguez-Marín, Miguel Sama
Venue: Computers Mathematics with Applications (2009)

In this work we establish necessary and sufficient conditions for weak minimizers of a constrained set-valued optimization problem. These conditions are given by means of multiplier rules formulated in terms of contingent epiderivatives of scalar set-valued maps. We consider that the image spaces are finite dimensional and the set-valued maps are convex and stable. For these conditions, our results provide a scalar version of analogous existing results in the literature under weaker existence conditions. Moreover we prove that the multiplier rules can be computed in terms of the directional derivative of associated maps of infima.

Authors: R. D. Patidar, S. P. Singh
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 02 (2009)

This paper presents a control algorithm for improving the performance of a three-phase, four-wired (3P4W) active power filter (APF) under unbalanced and distorted supply voltages. A low pass filter (LPF) is designed to filter the nonsinusoidal supply voltages. The minimal optimal values of active power filter source reference currents are estimated in natural a-b-c reference frame. The proposed method is capable for harmonics suppression, reactive and neutral current compensation and load balancing in three-phase four-wire (3P4W) distribution systems. Extensive simulation is carried out under MATLAB Simulink environment. Various simulation results are presented with ideal and distorted mains condition to shows the effectiveness of the algorithm.
Adaptive Objects Tracking by Using Statistical Features Shape Modeling and Histogram Analysis
Authors: Concetto Spampinato
Venue: Proceedings of the 2009 Seventh International Conference on Advances in Pattern Recognition (2009)

We propose a novel method for object tracking using an adaptive algorithm based on statistical analysis of objects shape. To track objects in video sequence, we use a sys-tem that combines two algorithms: a histogram analysis algorithm and a statistical shape features modeling algorithm. The main improvement of the proposed system with respect to the others present in literature is that we do nonuse any a priori knowledge about how objects look like.This no apriori model has been carried out by computinga model that takes into account the statistical behavior of the most important objects features over the whole video frames. Moreover, an adaptive mechanism allows us tore set the statistical model creation when such a model is too much dissimilar from the real blobs features. Experiments on some real world difﬁcult scenarios of low resolu-tion videos and in unconstrained environments demonstrate the very promising results achieved.
Using MDE to Build a Schizophrenic Middleware for Home/Building Automation
Authors: Grégory Nain, Erwan Daubert, Olivier Barais, Jean-Marc Jézéquel
Venue: Proceedings of the 1st European Conference on Towards a Service-Based Internet (2008)

In the personal or corporate spheres, the home/office of tomorrow is soon to be the home/office of today, with a plethora of networked devices embedded in appliances, such as mobile phones, televisions, thermostats, and lamps, making it possible to automate and remotely control many basic household functions with a high degree of accuracy. In this domain, technological standardization is still in its infancy, or remains fragmented. The different functionalities of the various appliances, as well as market factors, imply that the devices that control them communicate via a multitude of different protocols (KNX, LonWorks, InOne). Building a high level middleware to support all the appliances seems to be a reasonable approach. However, market factors has shown that the emergence of a unique and universal middleware is a dream. To solve this issue, we have built a new generation of schizophrenic middleware in which service access can be generated from an abstract services description. EnTiMid, our implementation of schizophrenic middleware, supports various services access models (several personalities): SOAP (Simple Object Access Protocol), UPnP and DPWS (Device Profile for WebServices). In this paper, we describe how these personalities are generated using a Model Driven Engineering approach and discuss the benefits of our approach in the context of a deployment of new services at the city level.
Functionally Layered Video Coding for Water Level Monitoring
Authors: Sakol Udomsiri, Masahiro Iwahashi, Shogo Muramatsu
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

This paper proposes a new type of layered video coding especially for the use of monitoring water level of a river. A sensor node of the system decomposes an input video signal into some kinds of component signals and produces a bit stream functionally separated into three layers. The first layer contains the minimum components effective for detecting the water level. It is transmitted at very low bit rate for regular monitoring. The second layer contains signals for thumb-nail video browsing. The third layer contains additional data for decoding the original video signal. These are transmitted in case of necessity. A video signal is decomposed into several bands with the three dimensional Haar transform. In this paper, optimum bands to be contained into the 1st layer are experimentally investigated considering both of water level detection and data size to be transmitted. As a result, bit rate for transmitting the first layer is reduced by 32.5% at the cost of negligible 3.7% decrease of recognition performance for one of video examples.

Authors: Don M. Minami
Venue: Proceedings of the June 7-10, 1982, national computer conference (1982)

The fixed/removable 5.25-inch Winchester drive provides combined computer peripheral support functions, such as mass storage, input/output, and backup. The 13.5-MByte total capacity (6.75 MBytes fixed/6.75 MBytes removable) is packaged in a unit about the size of a shoebox. Reliability has been the major factor in determining the design parameters of the fixed/removable drive. Not only has Winchester reliability been enhanced, but preventive maintenance has been eliminated. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

Investigating in scalability of opposition-based differential evolution
Authors: Shahryar Rahnamayan, G. Gary Wang
Venue: Proceedings of the 8th conference on Simulation, modelling and optimization (2008)

Differential Evolution (DE) is an effective, robust, and simple global optimization algorithm. Opposition-based differential evolution (ODE) has been proposed based on DE; it employs opposition-based population initialization and generation jumping to accelerate convergence speed. ODE shows promising results in terms of convergence rate, robustness, and solution accuracy. This paper investigates its performance on large scale problems. A recently proposed seven-function benchmark test suite for the CEC-2008 special session and competition on large scale global optimization has been utilized for the current investigation. Results interestingly confirm that ODE outperforms its parent algorithm (DE) on all high dimensional (500D) benchmark functions (F1-F7). By these supporting results, ODE is recommended by authors as an appropriate candidate for cooperative coevolutionary algorithms (CCA) to tackle with large scale problems. All required details about the testing platform, comparison methodology, and also achieved results are provided.
Combination of Global and Local Search for Real Function Optimization
Authors: Xinsheng Lai
Venue: Proceedings of the 3rd International Symposium on Advances in Computation and Intelligence (2008)

This article introduces a global optimizer based on combination of global and local search (OBCGL). OBCGL contains two populations, one for global search and the other for local search. OBCGL utilizes hill climbing method to select new individuals to form new generation instead of selection methods used in Genetic Algorithms (GAs). The algorithm's performance was studied using a test bed of real-valued functions with different degree of multi-modality. In all cases studied, we found that with two populations OBCGL works well.

Authors: Yongdong Wu, Mei Song, Lin Qiu, Junde Song
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 01 (2009)

This paper presents a new method to use correlator in modern communications after analysing the application and performance of the traditional correlator in detail. According to the results of simulation, the new method have more precise frequency and timing synchronization in wireless communications, which improves its ability against interference of multipath and frequency selective fading. Even in the circumstances of low signal to noise ratio (SNR: 0dB), it also has a very high accuracy of synchronization.

Venue: Microelectronics Journal (2009)

We have prepared, characterized and discussed the performance of AlGaAs/GaAs heterojunction bipolar phototransistor (HPT) including Zn delta-doped base. Due to the existence of Δ-doped sheets located in the middle of undoped GaAs base the Δ-doped HPT devices exhibit low dark current, nearly zero offset voltage, saturation voltage ~0.4V, and rise and fall times in ns range at wavelength of 850nm up to 6V of applied voltage. Due to avalanche multiplication behavior at the collector junction, an increased optical gain G>10 can be reached for applied voltages in the range of 6-12V. For voltages higher than the device breakdown voltage (~12V) switching and negative differential resistance (NDR) effect is measurable in the inverted mode of operation.

Improving Air Traffic Management with a Learning Multiagent System
Authors: Kagan Tumer, Adrian Agogino
Venue: IEEE Intelligent Systems (2009)

Air traffic management is a fundamental challenge facing the US Federal Aviation Administration (FAA) and, owing to the difficulties in improving the infrastructure, a problem in need of an algorithmic solution. A proposed multiagent approach assigns an agent to a navigational fix (a specific location in 2D space) and derives specific agent rewards that shape the agent actions. These agents aim to maximize their own local rewards, but their doing so leads to coordinated behavior that reduces global congestion.
Particle methods for modelling in mineral processing
Authors: Paul W. Cleary, Rob D. Morrison
Venue: International Journal of Computational Fluid Dynamics (2009)

The Discrete Element Method (DEM) is a computational method that is well suited for modelling flows of particulate materials in mineral processing. Smoothed Particle Hydrodynamics is a particle-based method for modelling fluid flows and is highly compatible with DEM allowing relatively easy coupling of particulate and liquid phases. In this article, we will explore recent modelling of some important unit processes used in mineral applications using these particle-based methods. Specifically, models of a particle and slurry motion are presented for a full three-dimensional semi-autogenous mill at several different scales. These are used to explore particulate motion in the charge, slurry motion within the charge, discharge through the grate and pulp lifter system and the varied breakage processes occurring within these machines. The importance of rock shape and its evolution on the balance of breakage mechanisms within the mills are discussed. Finally, an example of application of DEM to predict particle behaviour in a twin deck vibrating banana screen is presented.
Analyzing Agent-Oriented Service Models based on SRMO
Authors: Tong Li, Lin Liu
Venue: Proceedings of the 2008 International Workshop on Service-Oriented Computing Consequences for Engineering Requirements (2008)

This paper reports our experiences in analyzing service models based on the Service Requirements Modelling Ontology (SRMO) with an agent-oriented reasoning procedure. The service model in this paper adopts concepts from the strategic actor based early requirements modelling framework i* and extended with service manipulation rules. By mapping a static conceptual service model into a runtime situation, the set of service manipulation rules can be simulated and validated against expected service requirements. The Service-Oriented Model Reasoner (SOMR) has been designed and implemented as a plug-in of the Organization Modelling Environment (OME). Our testing results have shown that the agent-oriented service model reasoner can be used as an effective rule debugger and service model simulation tool.

Image Quality Assessment for Color Halftone Images Based on Color Structural Similarity
Authors: JunHak Lee, Takahiko Horiuchi
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

This paper proposes a new color halftone image quality assessment method based upon the color structural similarity measure with considering the human visual characteristics. To include the color visual characteristics, we carry out the color filtering for each luminance, red-green, and blue-yellow channels. Then, we apply the color structural similarity measure to the color filtered images, which are the reference image and the halftoned image, to evaluate the localized structural difference. By considering those characteristics, in this paper, the assessment of the color halftone images can be realized. We apply the proposed measure to the various kinds of color halftone images and confirm that the proposed measure can give reasonable results compared with the results by subjective evaluation.

Personalized Image Recommendation
Authors: Yuli Gao, Hangzai Luo, Jianping Fan
Venue: Proceedings of the 15th International Multimedia Modeling Conference on Advances in Multimedia Modeling (2009)

We have developed a novel system to support personalized image recommendation via exploratory search from large-scale collections of weakly-tagged Flickr images. First, topic network is automatically generated to index and summarize large-scale collections of Flickr images at a semantic level. Hyperbolic visualization is used to allow users to navigate and explore the topic network interactively, so that they can gain insights of large-scale Flickr image collections at the first glance, build up their mental query models quickly and specify their queries more precisely by selecting the visible image topics directly. Second, the most representative images are automatically recommended according to their representativeness for a given topic and they are visualized according to their inherent visual similarity contexts, so that users can assess the diverse visual similarity contexts between the images interactively and evaluate the relevance between the recommended images and their real query intentions effectively. Our experiments on large-scale weakly-tagged Flickr image collections have obtained very positive results.
The case for intentional networking
Authors: Jason Flinn, T. J. Giuli, Brett Higgins, Brian Noble, Azarias Reda, David Watson
Venue: Proceedings of the 10th workshop on Mobile Computing Systems and Applications (2009)

Wireless infrastructures are increasingly diverse, complex, and difficult to manage. Those who restrict themselves to homogeneous, managed campus or corporate networks are a vanishing breed. In the wild, users are confronted with many overlapping infrastructures with a broad variety of strengths and weaknesses. Such diversity of infrastructure is both a challenge and an opportunity. The challenge lies in presenting the alternatives to applications and users in a way that provides the best possible utility to both. However, by managing these many alternatives, we can provide significant benefits, exploiting multiple networks concurrently and planning future transmissions intelligently.
On the diameter of geometric path graphs of points in convex position
Authors: Jou-Ming Chang, Ro-Yu Wu
Venue: Information Processing Letters (2009)

For a set S of n points in convex position in the plane, let P(S) denote the set of all plane spanning paths of S. The geometric path graph of S, denoted by G"n, is the graph with P(S) as its vertex set and two vertices P,Q@?P(S) are adjacent if and only if P and Q can be transformed to each other by means of a single edge replacement. Recently, Akl et al. [S.G. Akl, K. Islam, H. Meijer, On planar path transformation, Inform. Process. Lett. 104 (2007) 59-64] showed that the diameter of G"n is at most 2n-5. In this note, we derive the exact diameter of G"n for n>=3.
Dispute resolution and e-government
Authors: Ethan Katsh
Venue: Proceedings of the 2nd International Conference on Theory and Practice of Electronic Governance (2008)

Dispute resolution is a core governmental activity and one that occurs not only in courts but in almost all administrative and regulatory agencies. At times, a government agency will be a party to a dispute and at other times the agency will attempt to resolve conflicts between citizens, businesses or groups. As more governmental processes go online, there is a clear need for dispute resolution processes and procedures that are also online and that are transparent, efficient and effective. This panel will explore current progress in government-based online dispute resolution.
