A real-time mobile GIS based on the HBR-tree for location based services
Authors: Jae-Kwan Yun, Dong-Oh Kim, Dong-Suk Hong, Moon Hae Kim, Ki-Joon Han
Venue: Computers and Industrial Engineering (2006)

Recently, as the growth of the wireless Internet, PDA, and HPC, the focus of research and development has been changed to LBS (location based service). To offer LBS efficiently, there must be a real-time GIS platform that can deal with dynamic status of moving objects and a location index which can deal with the characteristics of location data. Therefore, in this paper, we studied the real-time mobile GIS based on the HBR-tree to manage mass of location data efficiently. The real-time mobile GIS mainly consists of the HBR (Hash Based R)-tree and the real-time GIS platform. The HBR-tree is a combined index type of the R-tree and the spatial hash index. Although location data are updated frequently, update operations are done within the same hash table in the HBR-tree, so it costs less than other tree-based indexes. The real-time GIS platform consists of a real-time GIS engine, a middleware, and a mobile client.

Cisco IP Telephony: Planning, Design, Implementation, Operation, and Optimization (Networking Technology)
Authors: Ramesh Kaza, Salman Asadullah
Venue:  (2005)

The comprehensive guide to planning and implementing your Cisco IP Telephony system, as shown by the experts. Understand how to work through the different implementation phases of a Cisco IP telephony solution Plan your implementation with tools and guides from the most seasoned experts in the industry Avoid pitfalls in the process with best-practice suggestions and other tips derived from years of actual implementation experienceCisco IP Telephony: Planning, Design, Implementation, and Operation of the IP Telephony Network, is a guide for network engineers as they go through the deployment of a Cisco IP telephony (IPT) solution. Although an IPT system brings several benefits to an organization, understanding all the components of that system is necessary for a successful implementation. Engineers tasked with implementation must also keep in mind that the architecture they are installing must be scalable in the future. The authors of this book, Ramesh Kaza and Salman Asadullah, have taken an approach to address the questions that come to these engineers while planning, designing, implementing, and operating the Cisco IPT solutions. The deployment process has been divided into four phases: Planning, Design, Implementation, and Operation (PDIO). Each phase provides specific details about the tasks involved and best practices for successful implementation of the IPT solution.This book also contains pre-designed questionnaires and assistance tools that will help engineers determine the requirements of each phase of the PDIO cycle. This book is written by experts from Cisco with extensive experience in implementing these solutions. Readers are provided step-by-step explanations, specific details, and best practices acquired by the authors while working with the top Cisco IPT customers.
Swarm-based Active Tunable Routing for Overhead Reduction in Multiservice Networks
Authors: Constandinos X. Mavromoustakis, Helen D. Karatza
Venue: Proceedings of the 39th annual Symposium on Simulation (2006)

The explosive growth of multimedia and other bandwidth intensive applications has resulted a rapid increase in the size of the traffic loads that needs to be supported by modern networks. This paper describes the combination of the active network concept with swarm based control method for optimized multiclass QoS priority routing. This hybrid scenario uses the bandwidth clustering approach (triggered clusters). The packets follow a predetermined path initialized and allocated by swarm based packets, blindly and without any global knowledge of network conditions. In this work this mechanism is associated with the triggered pheromone explored at different simulation sessions and does not require message brokers to fulfill multiclass QoS demands. The pheromone enforcement model that is indicated increases the overall response of the system. Simulation results depict the performance and robustness of the scheme in terms of the end-to-end delay, available bandwidth and packet loss under different traffic measures.
Improving nearest neighbor classification with cam weighted distance
Authors: Chang Yin Zhou, Yan Qiu Chen
Venue: Pattern Recognition (2006)

Nearest neighbor (NN) classification assumes locally constant class conditional probabilities, and suffers from bias in high dimensions with a small sample set. In this paper, we propose a novel cam weighted distance to ameliorate the curse of dimensionality. Different from the existing neighborhood-based methods which only analyze a small space emanating from the query sample, the proposed nearest neighbor classification using the cam weighted distance (CamNN) optimizes the distance measure based on the analysis of inter-prototype relationship. Our motivation comes from the observation that the prototypes are not isolated. Prototypes with different surroundings should have different effects in the classification. The proposed cam weighted distance is orientation and scale adaptive to take advantage of the relevant information of inter-prototype relationship, so that a better classification performance can be achieved. Experiments show that CamNN significantly outperforms one nearest neighbor classification (1-NN) and k-nearest neighbor classification (k-NN) in most benchmarks, while its computational complexity is comparable with that of 1-NN classification.
Exact Inferences in a Neural Implementation of a Hidden Markov Model
Authors: Jeffrey M. Beck, Alexandre Pouget
Venue: Neural Computation (2007)

From first principles, we derive a quadratic nonlinear, first-order dynamical system capable of performing exact Bayes-Markov inferences for a wide class of biologically plausible stimulus-dependent patterns of activity while simultaneously providing an online estimate of model performance. This is accomplished by constructing a dynamical system that has solutions proportional to the probability distribution over the stimulus space, but with a constant of proportionality adjusted to provide a local estimate of the probability of the recent observations of stimulus-dependent activity-given model parameters. Next, we transform this exact equation to generate nonlinear equations for the exact evolution of log likelihood and log-likelihood ratios and show that when the input has low amplitude, linear rate models for both the likelihood and the log-likelihood functions follow naturally from these equations. We use these four explicit representations of the probability distribution to argue that, in contrast to the arguments of previous work, the dynamical system for the exact evolution of the likelihood (as opposed to the log likelihood or log-likelihood ratios) not only can be mapped onto a biologically plausible network but is also more consistent with physiological observations.
A reinforcement learning algorithm to minimize the mean tardiness of a single machine with controlled capacity
Authors: Hadeel D. Idrees, Mahdy O. Sinnokrot, Sameh Al-Shihabi
Venue: Proceedings of the 38th conference on Winter simulation (2006)

In this work, we consider the problem of scheduling arriving jobs to a single machine where the objective is to minimize the mean tardiness. The scheduler has the option of reducing the processing time by half through the employment of an extra worker for an extra cost per job (setup cost). The scheduler can also choose from a number of dispatching rules. To find a good policy to be followed by the scheduler, we implemented a &lambda;-SMART algorithm to do an on-line optimization for the studied system. The found policy is only optimal with respect to the state representation and set of actions available, however, we believe that the developed policies are easy to implement and would result in considerable savings as shown by the numerical experiments conducted.

Combating information overload in non-visual web access using context
Authors: Jalal Mahmud, Yevgen Borodin, Dipanjan Das, I. V. Ramakrishnan
Venue: Proceedings of the 12th international conference on Intelligent user interfaces (2007)

Web sites are designed for graphical mode of interaction. Sighted users can visually segment Web pages and quickly identify relevant information. In contrast, visually-disabled individuals have to use screen readers to browse the Web. Screen readers process pages sequentially and read through everything, making Web browsing time-consuming and strenuous. The use of shortcut keys and searching offers some improvements, but the problem still remains. In this paper, we address this problem using the notion of context. When a user follows a link, we capture the context of the link, and use it to identify relevant information on the next page. The content of this page is rearranged, so that the relevant information is read out first. We conducted a series experiments to compare the performance of our prototype system with the state-of-the-art JAWS screen reader. Our results show that the use of context can potentially save browsing time as well as improve browsing experience of visually disabled individuals.

Towards a test&dash;bed for trading agents in electronic auction markets
Authors: Juan A. Rodríguez&dash;Aguilar, Francisco J. Martín, Pablo Noriega, Pere Garcia, Carles Sierra
Venue: AI Communications (1998)

We present a framework for defining trading scenarios based on fish market auctions. In these scenarios, trading (buyer and seller) heterogeneous (human and software) agents of arbitrary complexity participate in auctions under a collection of standardized market conditions and are evaluated against their actual market performance. We argue that such competitive situations constitute convenient problem domains in which to study issues related with agent architectures in general and agent&dash;based trading strategies in particular.The proposed framework, conceived and implemented as an extension of FM96.5 (a Java&dash;based version of the Fishmarket auction house), constitutes a test&dash;bed for trading agents in auction tournament environments, FM97.6.Finally, we illustrate how to generate tournaments with the aid of our test&dash;bed by defining and running a very simple tournament involving a set of rudimentary buyer agents.
Registration of partially overlapping surfaces by rejection of false point correspondences
Authors: G. Xiao, S. H. Ong, K. W. C. Foong
Venue: Pattern Recognition (2006)

We present a new algorithm for the registration of three-dimensional partially overlapping surfaces. It is based on an efficient scheme for the rejection of false point correspondences (correspondence outliers) and does not require initial pose estimation or feature extraction. An initial list of corresponding points is first derived using the regional properties of vertices on both surfaces. From these point correspondences, pairs of corresponding rigid triplets are formed. The normal vectors at the vertices of each corresponding triplet are used to compute the candidate rotations. By clustering the candidate rotation axes and candidate rotation angles separately, a large number of false correspondences are eliminated and an approximate rotation is decided, from which an approximate translation is also obtained. Finally, the optimal transformation parameters are determined by further refining the estimated parameters in an iterative manner. Mathematical analysis and experimental results show that the registration process is fast and accurate even when the objects are regularly shaped and contain many regionally similar surface patches.
What do people recall about their documents?: implications for desktop search tools
Authors: Tristan Blanc-Brude, Dominique L. Scapin
Venue: Proceedings of the 12th international conference on Intelligent user interfaces (2007)

This study aims at finding out which attributes people actually recall about their own documents (electronic and paper), and what are the characteristics of their recall, in order to provide recommendations on how to improve tools allowing users to retrieve their electronic files more effectively and more easily. An experiment was conducted with fourteen participants at their workplace. They were asked first to recall features about one (or several) of their own work documents, and secondly to retrieve these documents. The difficulties encountered by the participants in retrieving their electronic documents support the need for better retrieval tools. More specifically, results of the recall task indicate which attributes are candidates for facilitating file retrieval and how search tools should use these attributes.
Hybrid approach with an expert system and a genetic algorithm to production management in the supply net: Research Articles
Authors: Anna Ławrynowicz
Venue: International Journal of Intelligent Systems in Accounting and Finance Management (2006)

A new approach to solving production management problems in the supply net is proposed. An expert system designed to help companies in medium-term and short-term production planning is discussed. The proposed expert system considers alternative process plans for a job and outsourcing, when a bottleneck exists in the machine. The proposed hybrid system uses the output of the expert system as the input of the genetic algorithm. The output of the genetic algorithm is a near optimal schedule. The proposed method does not require any unrealistic assumptions. It can be used to solve highly complicated and non-linear functions of a realistic problem.

On the completion time distribution for tasks that must restart from the beginning if a failure occurs
Authors: Robert Sheahan, Lester Lipsky, Pierre M. Fiorini, Søren Asmussen
Venue: ACM SIGMETRICS Performance Evaluation Review (2006)

For many systems, failure is so common that the design choice of how to deal with it may have a significant impact on the performance of the system. There are many specific and distinct failure recovery schemes, but they can be grouped into three broad classes: RESUME, also referred to as preemptive resume (prs), or check-pointing; REPLACE, also referred to as preemptive repeat different (prd); and RESTART, also referred to as preemptive repeat identical (pri). The following describes the three recovery schemes: (1) RESUME: when a task is fails, it knows exactly where it stops, and can continue from that point when allowed to resume; (2)REPLACE: given a task fails, then when it begins processing again, it starts with a brand new task sampled from the same task time distribution; and, (3) RESTART: When a task fails, it loses all that it had acquired to up to that point and must start anew when upon continuing later. This is distinctly different from (2) since the task must run at least as long as it did before it failed, whereas a new sample, selected at random, might run for a shorter or longer time.
A service oriented architecture for wireless sensor and actor network applications
Authors: Jaco M. Prinsloo, Christian L. Schulz, Derrick G. Kourie, W. H. Morkel Theunissen, Tinus Strauss, Roelf Van Den Heever, Sybrand Grobbelaar
Venue: Proceedings of the 2006 annual research conference of the South African institute of computer scientists and information technologists on IT research in developing countries (2006)

The emergence of Wireless Sensor and Actor Networks (WSAN) has contributed significantly to the progress of ubiquitous and pervasive computing, but has also introduced new challenges. The authors researched this technology and its applicability to real-world scenarios through the Cerberus project. This paper offers a discussion of the processes the authors went through from initial contact with the technology to implementing a system based on it, as well as the problems faced while working with WSAN. These experiences indicate the need for a dynamic, mote and application-independent management system. A service oriented architecture (SOA) for the management of WSAN, which makes use of OSGi, is proposed and evaluated. This SOA allows for the updating and changing of the application largely independent of the mote configuration as well as for easy management of different types of motes and actors.
